PowerHA® SystemMirror® Smart Assist for DB2® extends an existing PowerHA SystemMirror configuration to include monitoring and recovery support for DB2 Universal Database™ (UDB) Enterprise Server Edition.

PowerHA SystemMirror Smart Assist for DB2 allows you to automatically configure PowerHA SystemMirror in an environment where DB2 is already configured to make non-partitioned DB2 instances highly available.

PowerHA SystemMirror Smart Assist cannot be used to configure a cluster in a partitioned (DB2 UDB DPF) environment.

To make use of PowerHA SystemMirror Smart Assist for DB2, the DB2 UDB software must be installed on all nodes that are going to be part of the cluster, and DB2 instances must be configured on some of the nodes. The shared physical disks that contain the DB2 instances must be configured on all cluster nodes that will serve as takeover nodes for the DB2 instances.

PowerHA SystemMirror Smart Assist automatically discovers your DB2 configuration and lets you create either one of the following cluster configurations:

  • A hot standby two-node cluster
  • A mutual takeover two-node cluster
  • A cluster with more than two nodes and more than two instances where some of the nodes serve as takeover nodes for the configured DB2 instances.
