REMOTE COPY SW ACCEL field (REMOTE_COPY_SW_ACCEL subsystem parameter)
The REMOTE COPY SW ACCEL field specifies whether Db2 uses software to control the remote copy process for active log output in peer-to-peer remote copy (PPRC) environments.
|Acceptable values:||DISABLE, ENABLE|
|Data sharing scope:||It is recommended but not required that all members use the same setting. DISABLE is recommended if the active log data sets are not on PPRC-enabled devices.|
- The hardware PPRC function is used if available; this setting is appropriate for non-PPRC environments.
- Host software is used. This option can improve overall Db2 performance in PPRC environments at the expense of some additional SRB CPU time in the xxxxMSTR address space. z/OS® 2.1 or later is required to support this function.
