FAST REPLICATION field (CHECK_FASTREPLICATION subsystem parameter)
The CHECK_FASTREPLICATION parameter specifies the type of replication that DSS COPY uses to copy objects to shadow data sets when it is invoked by the DB2® CHECK utilities. The CHECK utilities can stipulate fast replication as PREFERRED or REQUIRED.
| Acceptable values: | PREFERRED, REQUIRED |
| Default: | REQUIRED |
| Update: | option 22 on panel DSNTIPB |
| DSNZPxxx: | DSN6SPRM.CHECK_FASTREPLICATION |
This parameter applies to the CHECK utilities in all DB2 modes (conversion mode through new-function mode)
- PREFERRED
- The CHECK utilities direct DSS COPY to use fast replication only if FlashCopy® support is available.
- REQUIRED
- The CHECK utilities force DSS COPY to use fast replication, ensuring that object copies occur as quickly as possible. This reduces the opportunity for resource contention and unavailability. This option causes CHECK utilities to fail if FlashCopy cannot be used.
