This parameter has been deprecated since Version 9.5, but is still being used by pre-Version 9.5 data servers and clients. Any value specified for this configuration parameter will be ignored by the database manager in DB2® Version 9.5 or later releases. In Version 9.5, it has been replaced by the appl_memory configuration parameter.
This parameter does not have any effect on a non-partitioned database with concentrator OFF and intrapartition parallelism disabled.
