Modifying Logging Configurations
Entering the LOG Configurator
ULOG (UL) [NLOGPROCS = numberprocesses allowed ]
[USERSPERPROC =
usersperloggingprocess ]
NLOGPROCS controls the user logging ID (LID) table size. Lowering NLOGPROCS loses all
current logging ID information from the tape created by SYSGEN. If NLOGPROCS remains
unchanged or increases, the current logging ID information is copied to tape. The
minimum and maximum number of processes allowed are 2 and 128, respectively.
USERSPERPROC specifies the maximum number of users assigned to each configured logging
process. The minimum and maximum number of users per logging process are 1 and 1140,
respectively.
NOTE Changing NLOGPROCS takes effect when a tape is created and an UPDATE
CONFIG or INSTALL is conducted. Refer to Chapter 3 , “System Startup
Functions,” for information on installing or updating the operating system.
To set the number of processes or users per process, enter ULOG followed by the number of
processes or users:
log>ULOG 40 ** Number of Processes **
or
log>ULOG USERSPERPROC=40 ** Number of Users per Process **
Clearing Log Configuration Changes
If you desire to clear all LOG configuration changes made, enter the CLEAR command at
the LOG configurator prompt.
log>CLEAR
Once a SYSGEN> KEEP is done, the changes kept become permanent and CLEAR does not
remove them.
Holding and Saving Configuration Changes
Using the system logging and user logging commands described in the following sections
changes the LOG configuration specified in the SYSGEN command line or global
BASEGROUP command. These changes are temporary and are easily lost if not properly
saved.
Saving configuration changes is a two-step procedure. After you alter a configuration, you
must, first, hold the changes before exiting the configurator. Second, use the global module
KEEP command to save the changes.
To hold changes, enter the HOLD command at the LOG configurator prompt:
log>HOLD
You can work in a SYSGEN configurator, hold the changes, and continue working in other
SYSGEN configurators before saving the changes.
To save the changes, hold all desired changes, exit to SYSGEN’s global module, and issue
