REMOTE_COPY_SW_ACCEL in macro DSN6LOGP

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 or ENABLE
Default: DISABLE
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.
Online changeable: Yes
DSNZPxxx: DSN6LOGP.REMOTE_COPY_SW_ACCEL
DISABLE
The hardware PPRC function is used if available; this setting is appropriate for non-PPRC environments.
ENABLE
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 Version 2 Release 1 or later is required to support this function.
