Scheduling Anticipated Workload Changes
Often, system managers can predict the behavior of their system workload.
You know the performance requirements at 9 a.m. differ from those at 6
p.m. and that the weekday workload isn't the same as the weekend
workload. The Workload Manager allows you to plan for such changes in
the workload and adjust the workgroup configuration accordingly.
To make "proactive" changes to your workgroup configuration, you can
create individual configuration files for each type of workload and
introduce the new configuration at any time with the NEWWG command. The
following steps summarize this procedure. For more detailed information,
refer to "Creating a New Workgroup Configuration" in Chapter 3.
1. Create a workgroup configuration file in ASCII format.
It isn't necessary to create the file from scratch. For
convenience, use the WGFILE format of the SHOWWG command to write
the current configuration to a file, and then edit that file.
2. Use the VALIDATE option of the NEWWG command to check the file for
errors in syntax or semantics without replacing the configuration.
3. When you want to change the configuration, issue the NEWWG
command, specifying the name of the configuration file on the
command line.
4. To change the configuration at a specified time, include the NEWWG
command (that names the configuration file) in a job, and schedule
the job for streaming at the appropriate time.
