Enabling and disabling the debugging trace requires that the agent process, namely NSCHED$AGENT, be restarted at least twice, once to enable the debugging trace, and once again to disable the debugging trace. We recommend that the debugging trace be enabled only so long as necessary to reproduce the problem being analyzed, and that is due to the fact that the log files can grow quite large in a relatively short time.
1. Access the directory where the the file we need to modify resides. Execute the following command:
$ SET DEFAULT SYS$SYSTEM
2. Modify the file SYS$SYSTEM:NSCHED$AGENT_RUN.COM by executing the following command and
making the edits described below:
$ EDIT NSCHED$AGENT_RUN.COM
Find the following four lines of DCL and remove the "!" character comment delimiter:
$!AGENT_PORT = 5481
$!DEFAULT_DIRECTORY = 0
$!DEBUG_LEVEL = 0
$!RUN_DETACHED = 1
Next, change the DEBUG_LEVEL symbol from 0 to 6; the value 6 enables full tracing. The end
result is that you want the original four lines of DCL code to appear as follows:
$AGENT_PORT = 5481
$DEFAULT_DIRECTORY = 0
$DEBUG_LEVEL = 6
$RUN_DETACHED = 1
Next, scroll to or search for the following line of DCL code:
$ NSCHED$AGENT ! 'AGENT_PORT' 'DEFAULT_DIRECTORY' 'DEBUG_LEVEL' 'RUN_DETACHED'
and remove the "!" character comment delimiter so that the original line now appears as follows:
$ NSCHED$AGENT 'AGENT_PORT' 'DEFAULT_DIRECTORY' 'DEBUG_LEVEL' 'RUN_DETACHED'
Save the changes by exiting the editor.
3. When permissible, stop and restart the Job Management Agent be executing the following commands:
Once the agent has restarted, allow the agent to run as long as is deemed necessary
to capture sufficient information. At this time, you should tale any actions that are
necessary to reproduce the problem(s) that you are trouble-shooting.
4. Once sufficient data has been gathered, it will be necessary to stop and restart the agent once again
in order to disable the debugging trace. We recommend that you stop the agent, recover the log
files and then restart the agent.
To stop the agent, execute the following command:
Recover the following two files:
Rename the modified version of SYS$SYSTEM:NSCHED$AGENT_RUN.COM:
$ RENAME SYS$SYSTEM:NSCHED$AGENT_RUN.COM; SYS$SYSTEM:NSCHED$AGENT_DEBUG.COM
Note: If you edited NSCHED$AGENT_RUN.COM multiple times, then there will be more than one modified version of the file. If that is the case, manually inspect each version of the files and rename or delete as appropriate.
Make sure that the remaining version of NSCHED$AGENT_RUN.COM is the original version by verifying that all of the "!" character comment delimiters are still in place. See step 1 to review all of the changes that were made and ensure that none of the edits are present.
Restart the agent by executing the following command:
