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 |
|---|---|
| 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.
