[Oracle EBS] Purge Concurrent Request and/or Manager Data

One of the important area of Concurrent Manager tuning is monitoring the space usage for the subsets within each concurrent manager. When the space in FND_CONCURRENT_PROCESSES and FND_CONCURRENT_REQUESTS exceed 50K, you can start to experience serious performance problems within your Oracle Applications. When you experience these space problems, a specific request called “Purge Concurrent Requests And/Or Manager Data” should be scheduled to run on a regular basis. This request to purge can be configured  the request data from the FND tables as well as the log files and output files on accumulate on disk.

When the tables FND_CONCURRENT_REQUESTS and FND_CONCURRENT_PROCESSES reaches above 3000-4000 rows, the performance diminishes. You have to run Purge Concurrent Request and/or Manager Data program on a regular basis depending on the amount of request being run.

Query Find Size in KB for FND_CONCURRENT_REQUESTS 
SELECT (BYTES/1024)/1024 "Size in KB" from dba_segments where SEGMENT_NAME='FND_CONCURRENT_REQUESTS';

SELECT (BYTES/1024)/1024 "Size in KB" from dba_segments WHERE SEGMENT_NAME='FND_CONCURRENT_PROCESSES';
