CHECK_FASTREPLICATION in macro DSN6SPRM
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 NONE, PREFERRED, or REQUIRED.
Deprecated subsystem parameter: Non-default settings for CHECK_FASTREPLICATION are deprecated. Db2 12 supports these settings, but their use is discouraged, and support is likely to be removed eventually. For best results, use the default value REQUIRED.
| Acceptable values: | PREFERRED, REQUIRED, NONE |
|---|---|
| Default: | REQUIRED |
| DSNZPxxx: | DSN6SPRM.CHECK_FASTREPLICATION |
- 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.
- NONE
- The CHECK utilities direct DSS COPY not to use fast replication.
