Retry on closed Connection [message #1058185] Mon, 13 May 2013 07:03 Go to next message

I am using EclipseLink 2.4.1 with Postgres 9.1.

The calls to 
EntityManager.createNamedQuery(String, Class).getResultList()
and 
entityManager.createQuery(CriteriaQuery).getResultList()
behave differently with respect to network problems:

When a database connection is closed because the network is down any subsequent call to entityManager.createQuery(CriteriaQuery).getResultList() will fail with a "Connection is closed" exception. However, when calling EntityManager.createNamedQuery(String, Class).getResultList() the same exception occurs but EclipseLink retries the query. In DatabaseAccessor.basicBeginTransaction(AbstractSession) it detects a communication error and in AbstractSession.basicBeginTransaction(Accessor) it retries the query.

My question: Is this by design or is it a bug? Are there any configuration properties which control this behaviour?

Thank you.
Michael

It should retry the query in both cases, provided you are not in a database transaction.
Does the named query use JPQL, or native SQL?

Please include the exception stack trace.

Both cases are the first statement within a database transaction. Is this relevant? Do I have to query without an transaction if I want retry to work?

Native SQL.

Quote:

Here it goes. It is the stack trace which is produced after


  1. Establishing an connection with a successful criteria query
  2. Disabling the network on the server
  3. Runing into a query timeout (javax.persistence.query.timeout)
  4. Getting a Postgres exception "This connection has been closed" after reruning
    the criteria query
  5. Enabling the network on the server
  6. Getting a Postgres exception "This connection has been closed" after reruning
    the criteria query again (see stacktrace below)
  7. After that I run the native SQL query (with result set mapping) and it works, and after that I rerun the criteria query and it worked too (see below of the stacktrace is the logging included)



Thank you!

My guess is this is because it is in a transaction, and using native SQL.

When using JPQL, EclipseLink knows the query is just a read, so does not need to begin a database transaction, so can retry the query.
With native SQL, the SQL may require a database transaction, so one is started, so the query cannot be retried, without retrying the entire transaction, which EclipseLink cannot do. You need to handle this in your own code, with a try/catch around your entire transaction and retry.

You could try executing the query outside of a transaction, or set the query to be read-only ("eclipselink.read-only") or set the query hint "eclipselink.exclusive-connection"="false".

Thanks for the answer. However, it is the opposite way. The named query with native SQL works (retries the connection as expected) while the criteria query doesn't work (fails on closed connection).
