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:
