By default, the server does not timeout a transaction. That is, the server waits indefinitely for a transaction to complete. If you set a timeout value for transactions, if a transaction isn’t completed within the configured time, the Application Server rolls back the transaction.
In the tree component, select the Configurations node.
Select the instance to configure:
Select the Transaction Service node.
Enter the number of seconds before the transaction times out, in the Transaction Timeout field.
The default value of Transaction Timeout is 0 seconds. This disables transaction timeouts.
Restart the Application Server.
