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.
