Hibernate configuration files

hibernate.properties and hibernate.cfg.xml perform the same configuration functions, if hibernate.cfg.xml exists it takes precedence over hibernate.properties.

The configurations can include Datastore, SessionFactory, Connection Pool, Transactions, and Cache Provider.

Much if not all of this can also be specified in the persistence.xml and the *-ds.xml.

Generally the persistence.xml specifies only the persistence unit name, jndi-name, mode (create, drop, etc.) for an EE application and everything in a standalone application.
Generally the *-ds.xml specifies the data source connection parameters, jdbc url, driver class, credentials, connection test parameter, provider type (Oracle, MySQL, etc.).
Generally the hibernate.cfg.xml specifies the others.

hibernate.cfg.xml is placed in WEB-INF/classes
persistence.xml is placed in META-INF in jar with entity beans

Oracle JDBC ReadTimeout QueryTimeout

If a query exceeds the oracle.jdbc.ReadTimeout without receiving any data, an exception is thrown and the connection is terminated by the Oracle driver on the client. Unfortunately the session will still be queued on the database and continue to wait for locks, hold any current locks, and complete any DML/PL*SQL procedures that are pending on the server-side of the orphaned connection. If an application, on a another connection, due to ReadTimeout exception, retries DML/PL*SQL  which requires locks, those queries will queue behind the initial DML/PL*SQL. This will increase the workload exacerbating the situation. On applications with retries, this can be observed by querying the v$session table  or gv$session on RAC and noting new sessions started periodically based on the ReadTimeout interval. The sessions may often have the same SQL_ID and/or SQL_HASH_VALUE. If stmt.setQueryTimeout(Seconds) is issued and the statement exceeds the timeout, it will atte...

Locks held on Oracle for hours after sessions abnormally terminated by node failure

If a session holds db locks and is abnormally terminated (no fin/ack), the locks will persist until the db session is closed, typically around 2 hours and 12 minutes with default network tcp_keepalive settings. Abnormally terminated does not include CTRL C or kill -9. The ojdbc6 driver apparently has a shutdown hook thread that closes the connections in graceful shutdowns. The OS apparently closes the connections when processes are killed. Abnormally terminated might include power failure, firewall failures, Out Of Memory, OS/kernel crash, network connection failure, JBoss or other server node failure, etc. This was easily reproduced by creating a  process that connected to the db and updated a record but did not commit. While the first process was waiting, a second process with a contending update was started which blocked on the first update. The first clients network cable was then disconnected. The second clients transaction waited for approximately 2 hours until the databa...
