PEER RECOVERY field (PEER_RECOVERY subsystem parameter)
The PEER_RECOVERY subsystem parameter specifies whether the data sharing member participates in data sharing peer recovery.
Db2 12 introduces this subsystem parameter. It takes effect in function level 100. However, in coexistence Db2 11 members do not participate in peer recovery.
| Acceptable values: | NONE, RECOVER, ASSIST, BOTH |
|---|---|
| Default: | NONE |
| DSNZPxxx: | DSN6GRP.PEER_RECOVERY |
The PEER_RECOVERY subsystem parameter accepts the following values:
- NONE
- This member does not participate in peer recovery. Use this option if you have configured the z/OS Automatic Recovery Manager (ARM) to restart failed Db2 members. NONE is the default value.
- RECOVER
- This member is recovered by a peer member if it fails.
- ASSIST
- This member attempts to initiate peer recovery for other failed members. When this member detects a failure, it attempts to initiate a LIGHT(YES) restart for the failed member if it has not already been initiated, to recover the retained locks.
- BOTH
- Both RECOVER and ASSIST options are activated for this member.
