### To set a transaction timeout value

By default, the server does not time out 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.

1. In the tree component, select the Configurations node.

2. Select the instance to configure:

   - To configure a particular instance, select the instance's config node. For example, the default instance, `server`, select the `server-config` node.

   - To configure the default settings for all instances, select the `default-config` node.

3. Select the Transaction Service node.

4. 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.

5. Click Save.

6. Restart the Application Server.
