1. Getting Started This manual applies to members of the Visara Communications Servers family which includes models of the 1174 and SCON, running the LINCS communication server operating system. For simpler reading, the terms LINCS and LINCS platform will be used throughout this document to describe the LINCS OS and the 1174/SCON hardware. Although LINCS has been pre-installed on the hard drive of your LINCS platform it must be configured for your environment before you can operate it for the first time.
LINCS Configuration is contained in the file in the form of parameter equates. An example of the contents of such a file is shown below. Lineid=fet1 Ip=198.14.23.192 Tcp=1083 Router=198.14.23.100 Subnet=255.255.255.0 Mac=0200268bce19 Not all parameters are required. You must however, include the LINEID, IP, and TCP parameters as a minimum.

2. General Options Proceeding forward through the configuration panels from the Product Description panels, you next encounter the General Options panels. General Options Panel General Options LINCS C8.
LINCS Configuration When the LINCS has been IMLed with a default configuration (such as the first time the LINCS is IMLed, or if the Config key is pressed at state 500), there will not be a supervisor password defined. You may also choose not to define a password. If no password is in effect, ANY user may enter the password-protected utilities. Using a password is recommended. If the Configuration utility is entered for display purposes only (i.e.
Chapter 2. General Options Central Site Customization is always enabled when you IML with the Default Configuration (at state 500 on the LCD panel). Language Options Language Options Language: Translate Tables: Numeric Delimiter: Country Extended Code Page: LINCS C8.2 Central Control PRIMARY SECONDARY (01) U.S.
LINCS Configuration • User-Defined 1 • User-Defined 2 If your choice for Secondary Language was Disabled, the Translate Table option for Secondary Language must be Default. Use of the Translate Table Utility to create user-defined tables may have an effect on the functioning of the ASCII Definition Utility and on ASCII character translation. If you plan to create User-Defined Translate Tables, and your network includes ASCII, refer to Effects on ASCII for additional information.
Chapter 2. General Options Software Requirements The following languages have their own character generators. To correctly display all the characters in a particular language, that language’s character generator must be installed in the display station. Languages followed by an asterisk (*) are supported by both 3270 hosts and ASCII hosts. Languages that are not followed by an asterisk are supported only by 3270 hosts. All other languages use the Base character generator.
LINCS Configuration the secondary language. Each of these secondary languages, Latin/Greek, Latin/Cyrillic, and Latin/Thai, is a special version of Latin that is specific to the primary language, Greek, Cyrillic, and Thai. You do not have to select Latin as the secondary language for Greek, Cyrillic, or Thai. You can select any of the supported languages as a secondary language, or you can select no secondary language.
Chapter 2. General Options Example 1: Switching Sessions, Keyboard Layouts, and Code Pages 1. German is the current keyboard layout. 2. You switch to Session 2. The host for Session 2 has Spanish as the default language. 3. The new code page and keyboard layout are Spanish. Example 2: Switching Sessions and Code Pages, but not Keyboard Layouts 1. Session 1 is active and its host is configured for German as the default language. Spanish is the current keyboard layout. 2. You switch to Session 2.
3. Line Options A Line Options panel is displayed for each communication board assigned on the Product Description panel. Each board supports different protocols. During configuration, you select the protocol for each line on a particular board.
LINCS Configuration (2) Note that when determining the total connections on a board, the Network Device connections are multiplied by a factor of 6. For example, if you have 20 gateway circuits and 32 incoming connections, this would be treated as a total of 20+(32*6)=148 total connections. The factor is used because Network Device connections take more processing power than the other types of connections.

Chapter 3. Line Options CNC with Channel Path Filter Line Options/ESC1 LINCS C8.
LINCS Configuration Device High (Channel Address) For SNA: This is the last channel address LINCS will occupy on the channel for this CU. The Device High must be a value such that (Device Low + Number of Host Circuits + Number of Gateway Circuits - 1) is less than or equal to hexadecimal x’FF’, which is the highest channel address available on the channel. You should make a record of the channel addresses allocated on the Channel/SNA panel.
Chapter 3. Line Options Attention Delay The Attention Delay is an SNA option that allows the control unit to queue inbound data for a specified period of time before presenting an attention status to request a read channel program. The option gives the control unit the capability of queuing several read requests during the delay period and then request one read channel program to transfer all the data, thereby reducing the number of unsolicited attention status’s presented to the host.
LINCS Configuration Blocking Delay(msec) The Blocking Delay is the maximum period of time that LINCS will wait, once it has received inbound traffic, before it will send all data inbound. During this time interval, LINCS will collect inbound traffic and buffer it until one of two things occurs: 1) the Blocking Delay timer expires, 2) 32 KB of data has been accumulated (the maximum amount of data that can be sent inbound at one time). The default value that LINCS uses is 40 msec.
Chapter 3. Line Options Non-SNA Line Options/CHP2 LINCS C8.2 Central Control Line Protocol: Channel/Non-SNA Lower Limit Channel Address: Upper Limit Channel Address: Command Retry Support: Data Transfer Mode: Channel Burst Size: 20 3F Disable High-Speed Transfer 32 PF: 1-Menu 7-Back 8-Forw 9-Default 10-Done Lower Limit Channel Address For SNA: Starting Channel address LINCS will occupy on the channel. The address can be any hexadecimal number from x'00' to x'FF'.
LINCS Configuration For CTC: This is the last channel address LINCS will occupy on the channel through this channel interface. Since each LAN adapter associated with the IP Channel Bridge feature requires a single consecutive pair of addresses, the Upper Limit Channel Address should be an oddvalued number (01, 03, 05, etc.). For Non-SNA: The Upper Limit Channel Address corresponds to the last device session channel address.
Chapter 3. Line Options Attention Delay The Attention Delay is a Channel/SNA option that allows the control unit to queue inbound data for a specified period of time before presenting an attention status to request a read channel program. The option gives the control unit the capability of queuing several read requests during the delay period and then request one read channel program to transfer all the data, thereby reducing the number of unsolicited attention status’s presented to the host.
LINCS Configuration Steps in defining UCW/IOCP Definitions When you set up the UCP/IOCP definition for a Local connection, you should specify only one UCW/IOCP definition for each channel interface For example, if you are installing LINCS with multiple channel addresses configured, do not define a separate UCW/IOCP definition for each channel address; specify only one definition per channel interface. Two UCW/IOCP definitions would be required for a dual channel LINCS node; one per channel interface.
Chapter 3. Line Options attaches to the HSC board. The other end splits into four connectors. Each connector is capable of operating at full-duplex speeds of up to 8 Mbps. Each connector supports any of the following four physical layer interfaces: • RS232 • V.35 • X.21 The physical layer interface type is selected via a combination of one of two available PLIMs (physical layer interface modules) and one of eight available HSC communication cables.
LINCS Configuration There are three different options for Role field of LMI Options, which result in slightly different LMI Options sections in the panel: • User - shown above in the example panel • Network (Switch) • Disabled The Line Options panel for Frame Relay is followed by a panel for LLC Options on this Frame Relay line. LMI Options for Network (Switch) Role Line Options/HSC1.0 . . . LINCS C8.
Chapter 3. Line Options Dynamic PVCs The Dynamic PVCs field toggles to ENABLE or DISABLE the use of dynamic PVCs. If dynamic PVCs are DISABLED, LINCS will utilize only those DLCIs specified on the PVC definition panels and on the LLC circuit panels. This setting may be desirable for security reasons. Dynamic PVCs must be disabled for lines that do not have the LMI role set to User. If dynamic PVCs are ENABLED, LINCS will communicate over all new PVCs reported by LMI up to the 256 PVC board maximum.
LINCS Configuration If this field is set to the maximum value (4119), no fragmentation will occur at the Frame Relay layer and frame size will be determined by the value entered in the link profile. SNA over frame relay also has special considerations for frame size. Frame Relay Frame Size and Fragmentation The maximum reassembled received SNA frame size is 4105 (including TH, RH, and RU).
Chapter 3. Line Options Type of LMI The Type field toggles to define the type of LMI used to manage the Frame Relay link. Toggle choices are: • ANSI T1.617 Annex D (default) • LMI Rev 1 • CCITT Q.933 Annex A • Stratacom LMI LLC Options for Frame Relay This panel comes up any time that you select 802.2 LLC protocol on the Line Options panel for Frame Relay on the HSC card. Line Options/HSC1.0 LINCS C8.
LINCS Configuration Link Subsystem Name on Frame Relay LLC Options The field allows you to assign a name to identify the subsystem in alerts that are sent to the host (for example, SNA alerts). You can use the default value VISARALAN or assign a 6digit alphanumeric non-blank name. LU to PU Mapped Circuits LU to PU Mapping is not supported over Frame Relay, so this field must be set to 0 for HSC LLC links.
Chapter 3. Line Options The PVC definition panels are used when: • You need to configure the CIR for any PVC that cannot use the default CIR (which was configured on the line panel). DLCI addresses specified elsewhere in configuration (such as on the host circuit, gateway circuit, or APPN circuit panels) do not have to be defined on a PVC definition panel, if these PVCs can use the default CIR.

SDLC/DAP The SDLC Distribution Access Point (SDLC Concentration) feature enables LINCS to emulate a front end processor’s ability to poll remote PU 2.0 devices over SDLC links.
Chapter 3. Line Options SDLC/DAP Hardware Requirements SDLC/DAP is supported on the SCC and HSC card for downstream connections. With the SCC card, group polling is only supported when LINCS is attached to an FEP (LINCS is a secondary station). With the HSC, LINCS supports group polling as a primary or secondary station. Primary stations require configuring each downstream (secondary) connection on the Gateway Circuit panels.
LINCS Configuration not time out on the upstream link. LINCS will perform SNA segmentation as needed, both downstream and upstream. The SDLC DAP feature is responsible for maintaining the SDLC link, including error recovery. Note: If the upstream connection is Channel, and the downstream (DAP) uses an SCC, LINCS will perform outbound segmentation, but not inbound segmentation. LINCS supports both inbound and outbound segmentation if an HSC board is used for downstream (DAP) connections.
Chapter 3. Line Options REPLYTO This indicates the length of time that LINCS will wait for a reply before it logs a timeout for the device. IT should be at least the time required to read the maximum frame size at the operational baud rate. One second (default) is sufficient for 4800 baud or faster for 521 byte frames, or 9600 baud or faster for 265 byte frames. Enter a value from 1 to 99 in tenths of a second (10 is default.
LINCS Configuration XID Polling Interval for Inactive PUs The value of this parameter represents how often an XID is sent to downstream inactive PUs on the SDLC link by the DAP feature. A response to the XID by the downstream PU informs LINCS that the device is available for communication. Note that no activity is initiated by LINCS on the upstream side for the downstream PU until the downstream device responds to the XID.
Chapter 3. Line Options BSC Line Code This field lets you determine the character set for the BSC line. Two toggle options are available: • EBCDIC (Default) • ASCII - The ASCII line code uses 7 bits with odd parity checking. BSC DFT Response The option selected for this item is important only if DFTs are to be attached to the LINCS node. You should obtain the appropriate value from the system programmer at your host site.
LINCS Configuration SCC X.25 Line Options Line Options/SCC1.0 LINCS C8.2 Central Control Line Protocol: X.25 Local DTE Address: X.25 Network Type: Transmit Clock: Link Layer Cmd/Rsp Role: Link Layer Window Size: Response Timer - T1 (.1 sec): Retry Count - N2: Receive Timer - T2 (.
Chapter 3. Line Options Link Layer Cmd/Rsp Role: This field determines whether this LINCS platform is to provide the link layer clocking. When set to DCE, LINCS will provide the transmit and receive clocks allowing direct attachment to another X.25 platform without use of modems. When set to DTE, a modem is required to provide clocks. Link Layer Window Size Select the link level window size that is consistent with the network subscription value. Values are 1 - 7, the default is 2.
LINCS Configuration Line Options/FET The Line Options/FET panel is used to define which protocols are to be supported by the 10/ 100 Mbps Ethernet card supported by LINCS, and what hardware or MAC address is to be used. An example of the panel is shown below. Line Options/FET1 LINCS C8.2 Central Control LAN Address: 0000 0000 0000 Media Type: Duplex Mode: Auto Negotiate Auto 802.
Chapter 3. Line Options This field contains the Ethernet node address of the LINCS node. It is a 12-character hexadecimal address, and can be any hex value you wish. Within the most significant byte, the lowest bit specifies a group address and the next bit specifies a locally administered address. Ethernet addresses configured by LINCS must be arranged in IEEE format where the most significant bit is on the right of each byte. 802.

LINCS Configuration MAC Layer Frame Format (IPX) This field indicates which MAC layer Frame Formats which are supported via the Ethernet LAN adapter for IPX on Ethernet. Note: Any or all of these frame formats can operate at the same time, and enabling more than one implies that LINCS will do routing. The network numbers must match those of the other servers on the LAN per frame type.
Chapter 3. Line Options Node Name Use this 16-character field to specify LINCS’ LAT node name. Valid characters are alphanumeric, dollar sign, period, hyphen, and underscore. The name must be unique on the LAT network. If the field is left blank, LINCS constructs a Node Name using the letters VISARA followed by the LAN address. Node Identification Use this optional 16-character field to provide additional node identification information.
LINCS Configuration Line Options/TRC Line Options/TRC1 LINCS C8.2 Central Control LAN Address: Token Ring Speed: Source Routing: 802.2 LLC: TCP/IP: IPX: 4000 1174 0000 16 Mbps without Early Token Release Enable With All Routes Broadcast Enable Disable Disable PF: 1-Menu 7-Back 8-Forw 9-Default 10-Done When paging forward, additional TRC line options panels may be displayed based on the selections made on this panel.
Chapter 3. Line Options LAN Address-TRC This field contains the Token Ring node address of the adapter. It is a 12-character hexadecimal address that can be locally or universally administered. Local administration permits you to assign the Token Ring address. Universal administration permits the assignment of unique addresses by a standards organization. The universally assigned address for each unit is contained in hardware on the Token Ring adapter (TRC) board.

The default is 30 seconds. Retry Count- LLC This field indicates the maximum number of times the LAN adapter transmits a checkpointing poll following the T1 response time expiration. Valid counts range from 01-99. The default is 7.
LINCS Configuration TN3270 Client Connections A valid number of host connections is 0 to 250. TN3270 Client Connections allows Network Devices running TELNET client software to receive 3270 data. LINCS acts as a TN3270 server for the TN3270 clients (Network Devices). Additional configuration options are on the TN3270 Client Definition panel, accessible from the Configuration full menu. TN3270 Client Connections requires the TN3270 Server Feature to be installed.
Chapter 3. Line Options TCP Quiet Time TCP requires 4.5 minutes of recovery time after a device crashes or for a reboot, but LINCS’ IML time varies according to configuration and hardware installed. This field allows you to define extra time beyond the normal boot time before TCP connections can be attempted. Default value is 0. (As soon as LINCS has IMLed, TCP can attempt connections.) Default Router Address Enter the address of the router on the network. Obtain this value from the system administrator.
LINCS Configuration SNMP Write Authentication String This 16-character string is required by the Network Management Station (the SNMP client) to modify MIB variables in LINCS. If left blank, LINCS will default the string to PUBLIC. MAC Layer Frame Format This is a Display Only field which indicates the MAC layer Frame Formats (protocols) which are supported via the Token Ring LAN adapter. Current Token Ring MAC layer Frame Formats (protocols) supported are 802.2 and SNAP. Token Ring 802.
Chapter 3.

LINCS Configuration This panel will be displayed if LAT connections are configured for any Ethernet board. The Identifier Control List refers to outgoing connections. The Access Control List refers to incoming LAT connections. The purpose of the Control List is to indicate access authorization. For example, if a server indicates access authorization of 12 is required, only LAT clients configured with an authorization level of 12 will have access to that server resource.
11. TN3270 Client Definitions The TN3270 Client Definition panel is used to map LINCS 3270 host resources to TN3270 clients. Through configuration of this panel, it is possible to assign specific LUs to a client, or give LUs from a pool (3270 Host Class). It is also possible to determine whether a password is required by a client to gain access. Not all TN3270 emulators are capable of handling the command chaining used by console devices. Most should work however as VTAM devices.
LINCS Configuration on the TCP/IP Options panel for one or more network interfaces. Note that you can have more TN3270 Client Definitions than the number of TN3270 Sessions specified on the TCP/IP Line Options panel for a specific network interface. The number configured for a specific line however, will limit the number of concurrent connections.
Chapter 11. TN3270 Client Definitions • Client: A TN3270, TN3270E, or TN3287 client may attempt to connect. If an address has been configured, only a client using that address will be allowed the connection. LINCS handles any command chaining data streams for the client. • Client PW: This is handled the same as a client request, except that the client will be challenged for a password. Do not use this definition for a TN3287 client.
LINCS Configuration This entry provides a session (address 06 for host “OS390_prod4” to a 1683/1783/1883 device or LINCS platform (SCON-25L or 1174) with an address of 207.15.182.113 only. The client must connect to the 2XL on incoming port 983. The client will be challenged for the password.

If a valid User ID and password is given, then a session from the 3270 Host Class called ‘ZOS_PROGRAMMERS’ will be given.
LINCS Configuration File entries may be of the following types: Name=resource Where the name can be any alphanumeric name, 12 characters or less, and the resource is a LINCS resource. LINCS resources that are valid include the name of a 3270 Host Class, or a host designator followed by a comma and the two hex character address of the desired session.
Chapter 11. TN3270 Client Definitions 7. The nickname file is not associated with any particular network adapter. This can simplify the configuration when using the SMS feature to balance user connections across multiple network interfaces. 8. By including the line ‘sensitive=yes’ as the first line of the nickname file, the remaining entries are treated as case sensitive.
12. Network Device Definitions The Network Device Definitions panels are displayed if a line which supports a Network Device has been configured. Network Device Definitions define the Network Devices that will connect to this LINCS node. Up to 128 concurrent connections are allowed per FET board. Up to 32 concurrent connections are allowed on the TRC and ETH boards. The Network Devices will have access to any of the features available to CUT mode devices.
LINCS Configuration Ports Each column position corresponds to a Network Device port for the indicated line. To enable a particular port for this Network Device definition, put a 1 in the column for that port. For example, a 1 in the first column (00) corresponds to ETH1.000. Ports in other LDDs Each column position corresponds to a Network Device port for the indicated line. These fields are protected, they show you which ports on this line are already assigned to another Network Device Definition.
Chapter 12. Network Device Definitions This panel is an example of what you will see if you toggle to LAT Display in the Device Type field. LAT Service Name This is a 16 byte alphanumeric field which defines the name of the LAT Display Service which will be offered to the ports enabled in this Network Device Definition.

LINCS Configuration Null/Space Conversion Toggle to ENABLE or DISABLE. This feature substitutes spaces for leading and embedded nulls when updates are sent to the host, if enabled. Delayed Power On Notify Toggle to ENABLE or DISABLE. This feature limits the number of sessions notifying the host at power-on, in order to alleviate excessive line traffic. LINCS does this by delaying the Power On Notify sent to the host for background sessions until the end user toggles sessions.
Chapter 13. Device Options Password Expires On This field is updated by LINCS when a PF4 has been entered twice on this panel with a nonzero value in the ‘Number of Days Password is Valid’ field. LINCS calculates the expiration date based on the ‘Number of Days Password is Valid’ field value. Length of Each Global Sequences This field indicates the maximum length that a single global sequence can be. Feature Memory is used to contain these global sequences.

LINCS Configuration (up to eight devices per mux). Assigning fewer than 8 devices to a mux, allows you to distribute your physical devices across more than the standard of 4, 8-port muxes providing more flexibility than a standard configuration. Device Profiles The Device Profiles panel will be displayed if any cut devices are configured (LAN, coax or ASCII). A given Device Profile contains customization parameters for all displays or printers using it.
Chapter 13. Device Options Power Off Action This is a toggle field that defines what will happen to sessions connected to a host when the device powers off. The following are the options. • None - The session state will remain intact when the device powers off. • Unbind SNA Sessions - All sessions connected to an SNA host will be unbound when the display powers off. Selecting this option will provide some security if a device is to be shared by multiple users.
LINCS Configuration ASCII Host You should choose this if you will be assigning a specific ASCII host (i.e., A0 - D7) on the Device Profile Assignments panel. If any ASCII hosts have been defined, this selection is displayed. ASCII Class All ASCII classes that have been defined are displayed as toggle choices. In this example, ENGR_VAX identifies an ASCII Host Class.

LINCS Configuration Windowing The Windowing feature enables you to create up to five windows on a CUT mode display station. These windows can simultaneously display five of the concurrent logical sessions that are possible with the Multiple Logical Sessions (MLS) feature. You can size, move, add, delete, and zoom the windows, and you can copy data from one window to another. In addition, you can set up windowing screen profiles that contain different arrangements of windows.
Chapter 13. Device Options • For example, if a DNS name was entered at the “Connect To” prompt to connect to a TCP/IP host, then the DNS name (truncated to 16 characters) will be displayed as the Host Identifier. • LAT Host : The Host Identifier is the LAT Service name to which the session is connected.
LINCS Configuration Note: Due to the extra coax processing required, performance degradation occurs if you’ve enabled PC File Transfer on ports that will not be performing file transfers, for example, CUT devices, printers, and DFTs. Note: When defining a profile to be used with Storage Tek LMUs, the PC File Transfer option should be enabled. SNA Data Display This is a toggle field which applies only to SNA sessions on the display. It determines when SNA data will be presented to a display.
Chapter 13. Device Options Auto Coax Recovery Auto Coax Recovery is a feature that will allow you to move a powered on display from one coax connection to another without having to power cycle the display to bring it active again. Enabling this option will cause LINCS to send a Reset poll to a device that has stopped responding to the normal poll in such a way that the device appears to have been powered down.
LINCS Configuration IP Host Class Access The matrix columns represent the sixteen IP Host Classes. Setting the value to 1 under column X allows devices in the profile to have access to IP Class X. Setting the value to 1 under the Dynamic Access column allows devices in the profile to dynamically connect to IP Host Classes by entering an IP address or DNS name on the TCP/ IP connect panel.

LINCS Configuration Inactivity Timeout Allows you to specify the amount of inactive time allowed before the display is logically disconnected from LINCS. Enter the number of minutes; allowable values are 0000 through 1440. 0000 indicates no timeout. LINCS warns the user by displaying a message on the status line one minute prior to disconnect. Synchronous Presentation For devices that are slow to update, LINCS will discard earlier screens, and draw the latest one.
Chapter 13. Device Options Printer Mode This is a toggle field with the following choices: • System - Printers using the profile are available only to hosts. Local prints from displays may not be directed to the printer(s). • Local (default) - Printers using the profile are available for local prints from displays. Hosts may not print to the printer(s). • Shared - Printers using the profile may be shared by hosts and displays doing local prints.
LINCS Configuration Printer Buffer Size This field lets you select an ASCII printer buffer size for local prints, that corresponds with the mod size of the transmitting coax terminal. Toggle to select one of the following: Mod 2, Mod 3, Mod 4, or Mod 5. LU3 Null Suppression This option suppresses any line that contains only null characters, eliminating an extra line return.

LINCS Configuration Device Profile Assignments panel Device Profile Assignments LINCS C8.
Chapter 13. Device Options Pressing PF9-Default will default the fields to the Host Assignments defined in each device’s Device Profile, but not the value in the Device Profile column. Note that a specific 3270 LU or Asynchronous ASCII Host may be assigned to multiple devices. This may be useful if a given user has two terminals (for example one at his/her desk and one in some other location) and needs the same Host Assignments at each location.
LINCS Configuration The second field of the Host Assignment for each session is one of two options: • a blank: the device will POR with the 3270 Connect menu displayed. • a number: you may input: • 02-255 (decimal) or 02-FF (hex) for SNA • 00-31 (decimal) or 00-1F (hex) for BSC or ESCON Non-SNA • 00-127 (decimal) or 00-7F (hex) for Bus and Tag Channel Non-SNA ASCII Host or Class The second field should contain a specific ASCII Host port number or an ASCII Class number.
Chapter 13. Device Options Note that a specific 3270 LU or Asynchronous ASCII Host port may be assigned to multiple device ports. This may be useful if someone has two terminals (one at his/her desk and one somewhere else) and needs the same Host Assignments at each location. By powering off one terminal, the host resources will be made available for the other terminal, if the Power Off Action field in the Device Profile/Host Assignments panel is set to Disconnect All Sessions.
LINCS Configuration Default Printer Assignments The default printer for a given display is: • The first printer class that the display is authorized to print to, if the device is authorized to print to any printer class. • The display’s printer port, if the display is not authorized to print to any class, HAP is enabled in the display’s device profile, and the HAP profile indicates that the printer is local or shared.
Chapter 13. Device Options All features which require feature memory are shown on the panel. If a particular feature is not configured, then the amount of feature memory shown will be zero (0). Presentation Space Storage refers to a collection of features that need memory, and are grouped together under that heading. These features all have to do with displays or printers (presentation), for which you must calculate storage needs.
LINCS Configuration IPX This field is set to 256K if more than one IPX protocol has been selected. Multiple MAC Frame Formats can be selected on one line, or more than one line can have IPX enabled. Central Site Customization Memory Requirements This is a protected field. 512KB of memory is required if Central Site Customization is enabled on the General Options panel.
Chapter 13. Device Options Extended (over 512) 3270 LUs Feature LINCS requires 1K of Feature Memory for each LU after the first 512 LUs. SCC Support This field applies to all hardware models except the 1174-15X. 128K of feature memory is required for each SCC configured on these Hardware Platforms (SCCs are configured on the Product Description panel). AIC 256K of feature memory is required if any ASCII ports are defined on the 1174-65X or SCON-22L models. 5550 Printer Sharing This is a protected field.
LINCS Configuration Presentation Space Storage for more information on the above features. • MLS (Multiple Logical Sessions) • Print Buffering • Screen Preservation during ASCII Setup Mode • ASCII Cut and Send • Calculator Session • LPD Server sessions Calculating Presentation Space Storage The following table documents the Presentation Space storage required for a single display session while using functions which require that a screen image be saved.
Chapter 13. Device Options For each device attached to LINCS, 8K of screen image memory and 1K of session information memory is allocated from base system memory. This allows devices to have a single session (and in some cases limited MLS) without requiring feature memory. When a device PORs, the amount of PS Storage memory to allocate is determined based upon the Device Profile. The Device Profile indicates the number of sessions and whether or not windowing and calculator memory will be required.
LINCS Configuration Determine the maximum number of print jobs which may be buffered from displays at any point in time. Enter this number in the worksheet titled Presentation Space Storage Memory Worksheet. ASCII Setup Presentation Space Storage memory is used to save a session’s screen image when the session enters ASCII Host Setup Mode. If no Presentation Space memory is available when an ASCII Host session enters Setup Mode, the session data will be lost.
Chapter 13. Device Options Presentation Space Storage Memory Worksheet Use the following worksheet to determine the total amount of memory for Presentation Space Storage.
14. RPQs Many RPQs are proprietary features that have been developed based upon particular customer needs. Other RPQs are options that are not included on the standard configuration panels due to their sensitive nature. The RPQ Panel lists all RPQs available to all LINCS node users. For additional information see RPQs in the LINCS Features document. RPQ Panel There are three RPQ panels: RPQs LINCS C8.
LINCS Configuration RPQs LINCS C8.
Chapter 14. RPQs RPQs LINCS C8.2 Central Control DESCRIPTION STATUS Suppress the automatic CLEAR key when connecting to a Shared Session During TN3270E negotiation, always tell client what LU was assigned Disable Disable PF: 1-Menu 7-Back 8-Forw 10-Done The RPQs panel is manually entered from the configuration menu. It will not automatically appear as you are paging through the configuration panels. Description of the individual RPQs follows.
LINCS Configuration Device Based Shift Status - The shift key status affects all sessions vs. only the foreground session. Presentation Space Update in File Transfer mode - This RPQ, when enabled, will force the 1174 to rewrite the entire screen when an Erase/Write is received and the device is in File Transfer mode.
Chapter 14. RPQs LANSYS Delay in Milliseconds - This RPQ allows the customer to insert a delay for LANSYS to wait before sending a response to the client workstation. This delay is neccessary for some Ethernet attached device platforms when configured with certain protocol stacks to allow the client workstations to work with these slower stacks. Otherwise the client workstation may not be ready for the response sent by the 1174.
LINCS Configuration Map “Any” LUs to “Public” LUs - A request for “Any” LU from an IPX client is treated as a request for a “Public” LU. LUs will be pulled from a Host Class called “Public” if such a class is configured. If no class by that name is configured, then any unused available LU may be given to the client. MAP “PUBLIC” LUs to “ANY” LUs - will treat an IPX 3270 request for a “PUBLIC” LU as if it were a request to receive any LU configured for the requested service name.
Chapter 14. RPQs Send BELL char (07) when ASCII display Input Inhibited – This RPQ causes a BELL character (hex 07) to be sent whenever the ASCII display experiences an Input Inhibited to alert the operator that the Input Inhibit has occurred. Many ASCII emulations do not support the necessary 25th line to allow viewing of all of the session data and the status line at the same time. ESCON Loopback Mode - The use of this option is for diagnostic purposes only and requires the use of an ESCON loopback plug.
LINCS Configuration Ignore all LU requests from TN3270 clients - The normal value for this option (‘Disabled’), results in LINCS attempt to honor any request for a specific host, address combination from the TN3270 client at connection time, as long as the format of the request is valid. This attempt overrides what has been configured for that device. Enabling this option will cause LINCS to ignore all such requests from the clients and only permit what has been configured to be assigned.
Chapter 14. RPQs Allow a user to commandeer a 3270 session already in use - When a user connects into the SCON, and is given a connect panel to request a session from, they have an additional option that allows them to take a session that is already assigned and in use by another user, by specifically requesting the session and performing the commandeer function. The person from which the session has been taken will be given a connect panel from which they can take their session back if needed.
15. Configuration Complete While in the Configuration Utility, pressing PF10-Save on an any panel, takes you to the Configuration Complete panel and causes all Configuration data to be examined for inconsistencies. If any inconsistencies are present, a message will be displayed to direct you to the panel containing the error. Upon paging to the panel in error, the specific warning message will be displayed.
LINCS Configuration powerful card, the VHP. One VHP will normally supply all the processing requirement for any number of HPP cards that are indicated. The only exception is when the APPN feature has been enabled and the HPP requirement indicates a value of 2 or more. In this case only, a second VHP would be required. Note that several models of LINCS platforms come with a VHP included as part of the base hardware, thus providing all the processing support required unless APPN is enabled.
Chapter 15. Configuration Complete Supervisor Password This field specifies when the new supervisor password will take. Options are After IML (default) and Immediate. Resource Authorization Matrix on Apply Configuration Changes If Immediate is chosen, the Resource Authorization Matrix from each Device Profile in the “working copy” will be copied to the corresponding Device Profile in the current configuration. Any resources which devices are currently using will not be taken away.
LINCS Configuration ASCII/Telnet Password Making a change to the Password that is used for access by ASCII or Telnet clients can be made to take affect Immediately, and when doing so, users that already connected will not be disconnected, but on subsequent attempts to connect will be required to provide the new password. Passwords used by Telnet and/or TN3270 clients that are defined in the nickname.sys file are not affected by this configuration. Nickname.sys files can be refreshed with utility 3/5.
16. Configuration Backups Once you have created a working configuration, you will probably want to back the configuration up for disaster recovery purposes. There are 4 ways that you can back up your configuration. 1. Create the backup from the configuration utility. 2. Copy the configuration data object using Media Management. 3. Copy the configuration files using FTP. 4. Retrieve a copy of the configuration with the Visara eManager product.
LINCS Configuration Creating a Configuration Backup Using FTP Using an FTP client of your choice, connect into the SCON through the FET interface (interface must be configured for network access of course) using the User ID of ‘system’, and give the configured Supervisor Password, for your password. Next copy off the following two files: FIG$DATA.LOA and DOD$CFG.LOA. Make sure that you transfer the files in binary mode (not text mode).
