Hi, Sal.
I was the tech who helped mitigate the problem you were having with CA Automation Point today, and I'd to clarify what the problem was, what we learned, and how we resolved the issue.
PROBLEM IDENTIFICATION: you wanted to configure automation point to invoke an AP REXX program at startup. you already had AXCREXX and AXCREXX logging enabled in the global REXX settings which affect all of your session definition sets. You added an override for the one session definition set that you have defined for your site such that your AP REXX program is launched at startup. You were running Automation Point as a service and not using the Automation Point Desktop application. After defining the REXX program to launch at startup, you connected to your running AP with Remote Viewer client and then shutdown AP. You then started up AP using Remote Viewer, but we could not see any of SAY statements from your REXX output in your REXXLOG.LOG. You wanted to know why the messages were not appearing in your REXXLOG.LOG and how to configure the product so that they would output there.
SOLUTION IDENTIFICATION: we found that the global REXX logging settings affect the overriden rexx settings for your single session definition set, and that after this is setup and AP is shutdown, if we STOP the AP TRACE service and then START it again, and then startup AP, we are able to log the messages from your REXX program invoked at startup.
So the reason why the AP TRACE service continues running after the AP Desktop application and the AP Autostart Manager service is shutdown or stopped, respectively, is because it manages the tracing facility for the notification services, which runs independently from AP Desktop application and AP running as a service (axc2p.exe).
FUN AP FACT: the command to stop ALL AP services accessible through the Configuration Manager -> Infrastructure -> Services panel is 'STOPAP' (without quotes) issued at the Windows command prompt. You can also stop and start these services individually through the Services panel in the Configuration Manager GUI.
HTH,
Stephen
