Filtering Traces
Disabling Component Tracing (ZPHIHMI or ZPHITMI)
1. On the main menu, enter 99 (Trace) in Selection Number field; then press F1.
DSM/SCM displays the Trace screen.
2. Enter 2 in the Selection Number field; then press F1. Trace is disabled.
Disabling Component Tracing (ZPHITI)
1. On the main menu, enter 9 (Enable trace) in the Selection number field; then press
F1. DSM/SCM displays the Enable Trace screen.
2. Select the DSM/SCM component to disable tracing for, and enter the
corresponding number in the Selection Number field.
3. Press F6.
Disabling Host Database Manager Tracing
Delete the TRACEHDB file in the ZDSMSCM subvolume:
> PURGE [[$volume.]ZDSMSCM.]TRACEHDB
Because host database managers interact with the TRACEHDB file only when one
receives a request, the trace file does not close until a host database manager
receives a request.
Disabling Object Manager Tracing
To disable the Object Manager Tracing:
1. Run STOPSCM.
2. Delete files TRACECHK and TRACEOM from the location $DSMSCM.ZDSMSCM.
3. Run STARTSCM.
Filtering Traces
You can filter what is traced to reduce the disk space consumed by a trace and to
improve a trace record’s readability. Without filtering, trace files can quickly take up
exceedingly large amounts of disk space when tracing DSM/SCM activities.
To filter traces, create a TRACEINI file in the ZDSMSCM subvolume. DSM/SCM
executes tracing as follows:
1. When a DSM/SCM component starts up, it checks if tracing is enabled.
2. If tracing is enabled, the component next searches for a TRACEINI file.
3. If the file exists, the component searches the file for filtering instructions for that
component. If no file exists, tracing is not filtered for any components.
