The Subsystem Management workspace provides an overview of workload
related information about the DB2 subsystem that you are monitoring.
This workspace is comprised of the following views:
- Background Utilization (needle gauge), which shows
the percentage of available threads being used for background connections.
- Foreground Utilization (needle gauge), which shows
the percentage of available threads being used for foreground connections.
- Subsystem Management Statistics (table view), which
lists total counts, counts during the last sample period, and the "per second"
count for a variety of subsystem requests, abends, and thread statuses associated
with the System Resource Manager (SRM) system.
- Subsystem Management Summary (table view), which
lists thread availability and usage statistics for foreground and background
connections.
Based on the information that this workspace
provides, you can recommend changes, set up situations, and verify that your
recommended changes improve system performance.
