The agent for DB2 monitors DB2 database instances and databases while they are up and running on a given system. If the system fails, the agent detects the failure and takes the DB2 instances offline. VCS conducts failover to another system in the cluster, where the agent brings DB2 instances online.
For ESE single partition instances, the agent brings the DB2 UDB database instances online, monitors database processes, and shuts them down. For ESE multi-partition instances, the agent brings the DB2 UDB database partitions online, monitors the database processes at the partition level, and shuts down the database partitions.
