Examples of org.jpox.store.rdbms.RDBMSManager$MgmtTransaction

org.jpox.store.rdbms.RDBMSManager
An abstract base class for RDBMSManager transactions that perform some management function on the database.
Management transactions may be retried in the face of SQL exceptions to work around failures caused by transient conditions, such as DB deadlocks.
