	<longdesc lang="en">
	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)
