High availability and scalabilityA successful production environment requires database systems that are always available, with minimal if any planned outages, and that can be scaled quickly and easily as business requirements change.
Cluster administration
Transaction completion during cluster failoverYou can configure servers in a high-availability cluster environment to continue processing transactions after failover of the primary server.
Configuring the server so that transactions complete after failoverUse the FAILOVER_TX_TIMEOUT configuration parameter to configure the servers in a high-availability cluster so that transactions complete after failover.

Configuring the server so that transactions complete after failover

Use the FAILOVER_TX_TIMEOUT configuration parameter to configure the servers in a high-availability cluster so that transactions complete after failover.

The value of FAILOVER_TX_TIMEOUT indicates the maximum number of seconds the server waits before rolling back transactions after failure of the primary server. Set FAILOVER_TX_TIMEOUT to the same value on all servers in the cluster. For example, to specify 20 seconds for transaction completion, set the value of the FAILOVER_TX_TIMEOUT configuration parameter in the onconfig file to 20.

To disable transaction completion after failover, set the FAILOVER_TX_TIMEOUT configuration parameter to 0 on all servers in the cluster.
