Dynamic debugging of user sessions or schedulers

The dynamic debugging feature enables administrators to enable or disable the debugging or tracing information for a user/scheduler session, without the need to restart the server. When enabled, relevant debugging information of that session/scheduler will be written to the server log (sm.log). Once you have finished troubleshooting, you can then disable some debugging information for that user session or scheduler, using dynamic debugging; however some debugging information cannot be disabled using dynamic debugging, and in this case the user needs to reconnect to the server or an administrator needs to manually stop and then restart the scheduler, to disable such debugging information.

Caution If multiple sessions exist for one user account or scheduler (for example, one user logs in simultaneously from different clients or multiple instances of one scheduler have been started), the dynamic debugging settings specified for one of these sessions will take effect for all of the sessions of this user account or scheduler.

Dynamic debugging supported parameters

The following table lists debugging parameters can be enabled and disabled or can only be enabled in dynamic debugging.

Parameters can be enabled and disabled in dynamic debugging Parameters can be enabled but cannot be disabled in dynamic debugging
dbmonitorfiles: [file1],[file2]… dbtriggertrace
debugca:n dbstats
debughttp debugattachments
debugdiagnostics debugjni
debugscauto debugjavascript
debugvmmap debugadhocsql
debuglk debugfileio
debugstartup debugshutdown
debugrs debugprocesses
ir_trace debugdbtypes
rtm debugdbquery

Note Once you have completed debugging of a user session or scheduler using any of those parameters that cannot be disabled in dynamic debugging, you are recommended to re-connect the session or restart the scheduler to disable the parameters.
