Enabling Data Maps Caching

Enabling Data Maps Caching

To enable data maps caching, set the DMXCACHE_MAX_MEMORY_MB statement to a value greater than 0 in the DBMOVER configuration file.
This value configures the maximum size for the data maps cache in megabytes.
For information about the DMXCACHE_MAX_MEMORY_MB statement, see the
PowerExchange Reference Manual
.
Verify that the REGION size specified in the DTLLST step in the JCL is large enough to run the PowerExchange Listener job. For example, if you define DMXCACHE_MAX_MEMORY_MB=20, you might have to increase the REGION size by 20 MBs.
