You can set up your database system so that if a machine fails, the database server on it can run on another machine. On the Solaris Operating Environment, you implement failover support with Sun Cluster 2.1.
Sun Cluster 2.1 performs both failure detection and the restarting of resources in a clustered environment, as well as failover support for physical disks and IP addresses.
You can implement failover support for both single-partition and partitioned database systems. For details on setting up failover support for a single-partition database system, see "Setting up Failover Support for a Database System". For details about setting up failover support for a partitioned database system, see Chapter 25. "High Availability in the Solaris Operating Environment, Partitioned Database". For information about clients and clustered environments, see "Client Application Considerations".
| Note: | Do not use a kill -9 against the db2start process in a high availability environment. This action is not recommended in any environment, but in particular such an action may invalidate failover recovery in your high availability environment. |
