Running Traces
Running Traces
You can start a trace for any DSM/SCM component on the host system or on any
target system that is network connected to the host. The Planner and Maintenance
Interfaces provide trace functions to trace the execution of their requests. Traces can
help diagnose problems in DSM/SCM. These DSM/SCM components can be traced
from the specified DSM/SCM interfaces:
When you enable tracing for:

The Schedule Manager or Object Manager, tracing begins immediately and lasts
until you disable trace or end the DSM/SCM session.

The Host Database Managers, tracing begins when any Host Database Manager
receives a request.

Any other DSM/SCM component, tracing begins when a request that uses the
component starts processing. If you disable trace while an enabled component is
running, tracing for that component is not disabled until the request finishes. If you
do not disable trace, tracing continues until you end the session.
Note. The trace function slows DSM/SCM processing and uses significant disk space. It
should be enabled only under the direction of HP support personnel.
