Function of the TXTIMEOUT parameter

The TXTIMEOUT configuration parameter is specific to the two-phase commit protocol. It is used only if communication between a transaction coordinator and participant has been interrupted and must be reestablished.

The TXTIMEOUT parameter specifies a period of time that a participant database server waits to receive a commit instruction from a coordinator database server during a distributed transaction. If the period of time specified by TXTIMEOUT elapses, the participant database server checks the status of the transaction to determine if the participant must initiate automatic participant recovery.

TXTIMEOUT is specified in seconds. The default value is 300 (five minutes). The optimal value for this parameter varies, depending on your specific environment and application. Before you modify this parameter, read the explanation How the two-phase commit protocol handles failures.
