Because CMA updates administrative data that is usually read from a cache, a thread pool with the L2 cache disabled is required during the execution stages of migration. Contact your system administrator and ask for the name of a thread pool with the L2 cache disabled. This thread pool name must be entered in the batch controls used for CMA processing in the Thread Pool Name parameter.
Refer to Running Batch Jobs for more information about running CMA batch jobs.
The batch section of the Server Administration Guide also contains information on preparing and implementing thread pools and turning off the L2 cache.
Also note that after a successful migration, the target region now has new administrative data which needs to be part of the L2 cache. The existing thread pool workers should be restarted by your system administrators. In addition, it is recommended to restart the application server.
