How to change the sleep time parameter setting for Internal Concurrent Manager (ICM)
Solution

The sleep time parameter setting can be set during startup of the ICM.
For example: % startmgr PMON=6 sleep=45

Oracle Applications does not allow users to change the sleep time setting for the Internal Concurrent Manager (ICM) from within the application. The default setting is 60 seconds.

Sleep Time: This is the number of seconds that the ICM waits between times it looks for new concurrent requests. Optimum value for this parameter is system dependent and is based on the number of worker queues and the system's cpu power. It is necessary to achieve a balance between leaving requests pending and too frequent pooling (with the associated high rate of table scans of FND_CONCURRENT_REQUESTS and wastage of resources). A thirty to forty second wait is recommended. Anything less than ten seconds will degrade performance. The default value of 60 seconds should be decreased.
