Active Users Concurrent Program Never Completes After Clone

Active Users Concurrent Program Never Completes After Clone

Recently i have faced an Issue in clone (R12). Everything worked as expected, except for Active Users Concurrent program which never completed when submitted. The status remains Running – Normal for hours together. But “Prints environment variable values” concurrent program completed within no time.

This is how the issue was approached and resolved.

1. This is not a concurrent manager (FNDLIBR) issue, since the concurrent managers came up without any problem. – This eliminates concurrent manager to be part of the problem.
2. How about running some other concurrent program viz., Users of a responsibility or Active Users of a Responsibility. Same behaviour as Active Users – request never completes.

3. Now it is clear that the problem is with concurrent programs which has (Oracle Reports) .rdf defined as an executable, since “Prints environment variable values” completed sucessfully.

Thinking it could be a clone issue, i recompiled all the reports using adadmin, still the same issue.

To get more information, i enabled trace for Active users concurrent program (How to enable trace)and resubmitted it. Strange, it didnt even generate a trace file, but a session had been established on the database. Checking for the sql being run by the session, returns nothing.

4. Decided to run the report manually from the command prompt.

Atlast got an idea ?

Error: [cache directory location] does not exist.

Where is this defined ?

Checking $INST_TOP/ora/10.1.2/reports/conf/rwbuilder.conf revealed that the cacheDir value defined (same as the missing directory) in this file did not physically exists on the server. Created the cache directory and

Re-ran the report manually from command prompt, the active users concurrent request completed successfully and even generated a trace file.
