ACP_MULTIPLE

   ACP_MULTIPLE enables (1)  or disables (0) the default creation of
   a separate disk XQP cache for each volume mounted on a different
   device type. Prior to Version 4.0, a separate ACP process was
   created for each device type if this parameter was enabled.
   Because ACP operations are now handled by the per process XQP,
   such separate processes are no longer created. In general, having
   multiple caches is unnecessary. One large cache is more efficient
   than several small ones. ACP_MULTIPLE can be overridden on an
   individual-volume basis with the DCL command MOUNT.

   ACP_MULTIPLE is an AUTOGEN and DYNAMIC parameter.
