Configuring manual peer recovery for the transaction service
Manual peer recovery processing is not the default setting; you must enable it through configuration. Administrator intervention is then required to trigger any peer recovery processing.
About this task
Complete this task if you want to use manual peer recovery for the transaction service. A scenario where you might want to use manual peer recovery is when your file system does not provide the required level of file locking support, and no constraints are in place to ensure that overloading or network partitioning does not occur. For more information, see the topic about how to choose between automated and manual transaction peer recovery.
After you configure manual peer recovery, your intervention is required only when a server fails and cannot be restarted; in this case, use the administrative console to specify which peer server performs recovery processing for the failed server.
Manual peer recovery configuration is provided by a group of policies known as static policies, where one policy definition is provided for each application server. Individual definitions are required to define server-specific configuration within the policy, which in this case is the identity of the server that initiates a peer recovery process.
