Turning off L2 Cache
Note: This facility should only be used where background processes specifically require it. Turning off the cache in other circumstances will adversely affect performance.
By default, the threadpools use a batch cache to load common configuration data to avoid excessive calls to the database. In some cases, it is desirable to disable the caching for a threadpool. To disable the cache on startup of the threadpool use the following command:
threadpoolworker.sh –l2 OFF –p <threadpoolname>
where <threadpoolname> is the name of the threadpool to start with the caching disabled.
Once the threadpool is started then all jobs that require caching off can be executed in this threadpool using the DIST-THD-POOL parameter (for online submission), com.splwg.batch.submitter.distThreadPool - Threadpool parameter in the job specific properties file or –p option on the submitjob command (see submitjob.sh - Submit Batch Threads (Legacy method of batch submission)).
