Scheduled Concurrent program breaks without any reason or log hint

Question

We have one concurrent program which calls a Custom PLSQL package scheduled to run every 5 minutes. Schedule runs fine for 15-20 days fine, after that, suddenly one instance of submission completes, and will not re-submit. We have always had problems with 2-3 concurrent programs like this.
The last instance of submission will show NO hint of error or reason why not submitting the next one, rather, it completes succesfully. It just doesn't put an extra line of "Successfully submitted with request ID #####" that we normally see in scheduled requests log file.
Applications Version is 11.5.9, Database at 10g.
Any help pls.
Thanks,
Rajkiran.

Answer 1

you can use this Doc :134035.1(ANALYZEREQ.SQL - Detailed Analysis of One Concurrent Request ) for the request that completed last time.
In addition could u let us know [1]what the custom req will be doing and [2]which CM is assigned to pickup the request.[3]does the request had picked up by CM after any time..[4]Does the CM which will pick up the request is busy with scheduling any other request at that time..
Hope any of above questions will give some Info..
BestRegards
