Interpreting Management Policy Data

This section explains the controls SRM uses to manage work, and where these controls can be found in SMF type 99. SRM algorithms set all the control values internally. All changes to the control values have trace entries in the subtype 1 record.

The SRM controls are:

• Dispatching priority
• MPL targets
• Swap protect time
• Storage targets
• Cap slices
• I/O priority
• Number of server address spaces
• Buffer pool management data

They are shown in the subtype 1, subtype 2, and subtype 5 records.
