cleanupConnection

protected void cleanupConnection(java.sql.Connection conn)

Cleanup the given database connection. This means restoring any modified auto commit or transaction isolation connection attributes, and then closing the underlying connection.

This is separate from closeConnection() because the Spring integration relies on being able to overload closeConnection() and expects the same connection back that it originally returned from the datasource.

See Also:: closeConnection(Connection)

closeConnection

protected void closeConnection(java.sql.Connection conn)

Closes the supplied Connection.

Ignores a null Connection. Any exception thrown trying to close the Connection is logged and ignored.

Parameters:: conn - The Connection to close (Optional).

rollbackConnection

protected void rollbackConnection(java.sql.Connection conn)

Rollback the supplied connection.

Logs any SQLException it gets trying to rollback, but will not propogate the exception lest it mask the exception that caused the caller to need to rollback in the first place.

Parameters:: conn - (Optional)

commitConnection

protected void commitConnection(java.sql.Connection conn)
                         throws JobPersistenceException

Commit the supplied connection

Parameters:: conn - (Optional)
Throws:: JobPersistenceException - thrown if a SQLException occurs when the connection is committed

Execute the given callback in a transaction. Depending on the JobStore, the surrounding transaction may be assumed to be already present (managed).

This method just forwards to executeInLock() with a null lockName.

Throws:: JobPersistenceException

                      throws JobPersistenceException

Execute the given callback having aquired the given lock. Depending on the JobStore, the surrounding transaction may be assumed to be already present (managed). This version is just a handy wrapper around executeInLock that doesn't require a return value.

Parameters:: lockName - The name of the lock to aquire, for example "TRIGGER_ACCESS". If null, then no lock is aquired, but the lockCallback is still executed in a transaction.
Throws:: JobPersistenceException
See Also:: executeInLock(String, TransactionCallback)

executeInLock

                                           throws JobPersistenceException

Execute the given callback having aquired the given lock. Depending on the JobStore, the surrounding transaction may be assumed to be already present (managed).

Parameters:: lockName - The name of the lock to aquire, for example "TRIGGER_ACCESS". If null, then no lock is aquired, but the lockCallback is still executed in a transaction.
Throws:: JobPersistenceException

                                  throws JobPersistenceException

Execute the given callback having optionally aquired the given lock. This uses the non-managed transaction connection. This version is just a handy wrapper around executeInNonManagedTXLock that doesn't require a return value.

Parameters:: lockName - The name of the lock to aquire, for example "TRIGGER_ACCESS". If null, then no lock is aquired, but the lockCallback is still executed in a non-managed transaction.
Throws:: JobPersistenceException
See Also:: executeInNonManagedTXLock(String, TransactionCallback)

executeInNonManagedTXLock

                                              throws JobPersistenceException

Execute the given callback having optionally aquired the given lock. This uses the non-managed transaction connection.

Parameters:: lockName - The name of the lock to aquire, for example "TRIGGER_ACCESS". If null, then no lock is aquired, but the lockCallback is still executed in a non-managed transaction.
