Introduction to MPE XL for MPE V System Administrators

Controlling System Resources and Security 

The parameters that control system resources and security, such as CPU,
job and session, and logon timeouts, are controlled in the system
configuration, and set at system startup.  These parameters can be easily
changed using the Miscellaneous Configurator of the SYSGEN Utility.
Refer to Chapter 3 of this manual for an overview of the SYSGEN Utility
and the various configurators.

Using SYSGEN's MISC Configurator, you can control the total duration of a
session, the amount of CPU time a job may use, and the amount of time a
user has in which to log on to the system.  The commands are,
respectively, SESSION CITIMEOUT, JOB CPUTIMEOUT, and SESSION
LOGONTIMEOUT.

These and other MISC Configurator commands are described in Table 7-1
.  The limits of their parameters are described in Table 7-2 .
Several of these commands are also discussed in the section on
Session-Related Parameters, below.
