Customizing the Operating System
5.2 Modifying Site-Specific Startup Command Procedures
5.2.7.13 Starting a DECnet or TCP/IP Network
Before starting the network, you must register your DECnet license and configure
your network. See Chapter 23 for information about setting up DECnet network.
If your system participates in a DECnet network, you might need to start the
DECnet software each time your system boots:
• If you are running DECnet for OpenVMS on your system, edit SYSTARTUP_
VMS.COM to delete the exclamation point (!) at the beginning of the
following command line:
$ @SYS$MANAGER:STARTNET.COM
• If you are running DECnet-Plus on your system, DECnet is started
automatically each time you boot your system.
If you are running a different network, you must run the appropriate startup
files for the particular network protocol. For example, three common net stack
startups are:
@SYS$STARTUP:TCPIP$STARTUP ! TCP/IP SERVICES
@SYS$STARTUP:NET$STARTUP ! DECnet-Plus
@SYS$STARTUP:STARTNET ! DECnet Phase IV
5.2.7.14 Starting the DIBOL Message Manager
Each node that will execute DIBOL programs must contain a line in
SYS$STARTUP:SYSTARTUP_VMS.COM that executes the command procedure
SYS$STARTUP:DBLSTRTUP.COM. This command procedure starts the DIBOL
Message Manager, used by DIBOL programs as an intermediary in passing
messages.
Example
SYSTARTUP_VMS.COM should contain a line as follows:
$ @SYS$STARTUP:DBLSTRTUP.COM
5.2.7.15 Defining the Number of Interactive Users
By default, when the system starts up, it limits to 64 the number of interactive
users allowed to log in.
To change the default value for the number of interactive users that you permit to
log in to your system at one time, define the symbol STARTUP$INTERACTIVE_
LOGINS to be the maximum number of users in SYSTARTUP_VMS.COM as
follows:
STARTUP$INTERACTIVE_LOGINS = = n
where n specifies the maximum number of interactive users that can log in at one
time.
Note
The number of interactive users is determined by the value authorized
by your VAX or Alpha computer license. Therefore, setting the number
higher than the license limit has no effect.
