jboss connectionpooling by subject, connection closed/no rec
Hi,
I'm using jboss 4.2.2.GA and I have a particular connection pooling setup:
<local-tx-datasource>
<!-- This datasource should only be used by the UI component
due to its peculiar connection pooling settings preventing use of more than 1 connection per subject.
-->
<jndi-name>ReferenceDataManagerDS</jndi-name>
<connection-url>${rdmds.connection.url}</connection-url>
<driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
<security-domain>OracleDbRealm</security-domain>
<max-pool-size>1</max-pool-size>
<idle-timeout-minutes>999999999999</idle-timeout-minutes>
<new-connection-sql>alter session set current_schema = ${rdmds.owner.username}</new-connection-sql>
<exception-sorter-class-name>
org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter
</exception-sorter-class-name>
<metadata>
<type-mapping>Oracle9i</type-mapping>
</metadata>
</local-tx-datasource>I use the connection pooling per subject config. The maximum pool size is set to 1 for reasons I won't explain here. The web application works fine as long as I don't hold up more than 1 connection per subject in a request cycle (but thats fine for the needs of my project).
However, if the connection is reset by peer, the connection is not automatically renewed and my application start throwing SQLException, Connection closed. Before I start investigating further, is there anything obvious that I missed that would help me avoid that ?
I'm considering adding a check-valid-connection-sql config something like:
SELECT * FROM DUAL
Even if that worked wouldn't that add unnecessary overhead? I mean shouldn't jboss find such unrecoverable exceptions by itself and let go the physical connection handle and recreate a new one ?
Here's the stack i'm getting:
