10Recovering Failed
Servers
A variety of events can lead to the failure of a server instance. Often one failure
condition leads to another. Loss of power, hardware malfunction, operating system
crashes, network partitions, and unexpected application behavior can all contribute to
the failure of a server instance.
Depending on availability requirements, you may implement a clustered architecture
to minimize the impact of failure events. (For information about failover in a
WebLogic Server cluster, see “Failover and Replication in a Cluster” in Using
WebLogic Server Clusters.) However, even in a clustered environment, server
instances may fail periodically, and it is important to be prepared for the recovery
process.
These topics describe WebLogic Server features for recovering failed servers
instances, guidelines for backing up the data required for restart, and instructions for
restarting failed server instances:
