To Configure How the GlassFish Server Recovers Transactions
Transactions might be incomplete either because the server crashed or because a resource
manager crashed. It is essential to complete these stranded transactions and recover from
the failures. GlassFish Server is designed to recover from these failures and complete
the transactions upon server startup.

While performing the recovery, if some of the resources are unreachable, the server
restart may be delayed as it tries to recover the transactions.

When the transaction spans across servers, the server that started the transaction can
contact the other servers to get the outcome of the transactions. If the
other servers are unreachable, the transaction uses the Heuristic Decision field to determine
the outcome.


In the navigation tree, expand the Configuration node.
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.
Select the Transaction Service node.
The Transaction Service page opens.
On the Transaction Service page, select the On Restart Enabled checkbox to enable
the recovery of incomplete transactions.
By default, the Enabled checkbox is not selected.
In the Retry Timeout field, type the number of seconds the GlassFish Server
tries to connect to an unreachable server.
The default value is 600 (10 minutes).
From the Heuristic Decision drop-down list, select the policy for unreachable servers in
a transaction.
Unless there is a good reason to select Commit, leave Heuristic Decision set to
Rollback (the default). Committing indeterminate transactions can compromise the data integrity of your
application.
Click Save.
Restart the GlassFish Server.
