Comparing MPE/iX Systems to MPE V Systems
Configuration
Configuration
Three areas of configuration have changed from MPE V to MPE/iX:
• General system configuration.
• Terminal and serial printer subsystem configuration.
• Terminal configuration settings.
These changes are discussed below.
General System Configuration
With MPE V computers, the INITIAL/SYSDUMP utility is used to
configure the system. MPE/iX computers require you to use a utility
called SYSGEN. SYSDUMP is an interactive program in which you
answer questions to enter configuration information. SYSGEN is a
command based interactive program. In SYSGEN, because you enter
commands instead of answering questions, you have more control over
the process of entering configuration data. SYSGEN also has other
advantages over SYSDUMP.
For more information on SYSGEN, see Introduction to MPE/iX for
MPE V System Administrators. Note that SYSDUMP is used to
configure the terminal and serial printer subsystem but SYSGEN is
not.
Terminal and Serial Printer Subsystem
Configuration
For MPE V computers, you must configure the asynchronous subsystem
by assigning device characteristics one-by-one through the use of
INITIAL/SYSDUMP dialogue questions. For MPE/iX computers, you
must use the< Node Management Configuration Manager (NMMGR) to
configure the Datacommunications and Terminal Subsystem (DTS).
With NMMGR, device profiles are created. A profile allows you to
specify values for a set of characteristics, such as a terminal type and
line speed, and apply those values to as many devices as you wish by
assigning the same device profile. This shortens the time needed to
configure devices into the subsystem.
Alternatively, some MPE/iX networks can include a network
management workstation running the OpenView DTC Manager. When
the OpenView DTC Manager is used, some aspects of serial device
configuration are offloaded from each MPE/iX system. These
characteristics are configured on the OpenView Windows Workstation
