NAME¶
ocf_heartbeat_db2 - Resource Agent that manages an IBM DB2 LUW databases in Standard role as primitive or in HADR roles as master/slave configuration. Multiple partitions are supported.
SYNOPSIS¶
db2 [start | stop | monitor | promote | demote | meta-data | validate-all]
DESCRIPTION¶
Resource Agent that manages an IBM DB2 LUW databases in Standard role as primitive or in HADR roles in master/slave configuration. Multiple partitions are supported.
Standard mode:
An instance including all or selected databases is made highly available. Configure each partition as a separate primitive resource.
HADR mode:
A single database in HADR configuration is made highly available by automating takeover operations. Configure a master / slave resource with notifications enabled and an additional monitoring operation with role "Master".
In case of HADR be very deliberate in specifying intervals/timeouts. The detection of a failure including promote must complete within HADR_PEER_WINDOW.
In addition to honoring requirements for crash recovery etc. for your specific database use the following relations as guidance:
"monitor interval" < HADR_PEER_WINDOW - (appr 30 sec)
"promote timeout" < HADR_PEER_WINDOW + (appr 20 sec)
