DUMPCLASS(FASTREPLICATIONDUMP): Specifying whether a dump class is required or optional
Explanation: FASTREPLICATIONDUMP is an optional keyword and is applicable only to dump classes associated with copy pools.
| Subparameter | Explanation |
|---|---|
| REQUIRED | DUMPCLASS(FASTREPLICATIONDUMP(REQUIRED)) indicates that every volume in a copy pool must have a successful dump copy to represent this dump class before the DASD backup version that is being dumped is replaced with a more recent DASD backup copy. After a DASD backup copy is replaced, you can no longer attempt to create dump copies from it. |
| OPTIONAL | DUMPCLASS(FASTREPLICATIONDUMP(OPTIONAL)) indicates that even though every volume in the copy pool might not have a successful dump copy to represent this dump class, if an FRBACKUP request is submitted to replace the DASD backup copy, the command is allowed to proceed. |
Example: In a particular environment, assume that two dump classes are defined to create two dump copies. One dump class is named ONSITE and the other OFFSITE. The dump copies created for ONSITE are the primary dump copies used for recovery and have the specification of FASTREPLICATIONDUMP(REQUIRED). The dump copies for dump class OFFSITE are secondary dump copies and have the specification of FASTREPLICATIONDUMP(OPTIONAL).
The FASTREPLICATIONDUMP keyword is mutually exclusive with the RESET keyword. Any attempts to define a dump class with both RESET and FASTREPLICATIONDUMP will fail.
