Oracle DB Configuration - redhat-consulting/jbpm-ee GitHub Wiki

###Environment:###

  • RHEL 6.5
  • Oracle XE Release 11.2.0.2.0

###Caveats###

  • If the user you are trying to connect with to your Oracle DB instance contains hyphen, please embed the user name in double quotes. i.e. "jbpm-timers"

###Instructions###

To set up xa transactions for the users we have in Oracle XE:

  • Follow this for the rest of the tasks: Example Oracle XA Datasource

  • On the database server log in as the oracle user, make sure that ORACLE_HOME, and ORACLE_SID are set and correct.

Make sure that you create the proper driver module and call it oracle.

For instance:

<driver name="oracle" module="com.oracle.ojdbc6">
    <xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
</driver>

And that there is a directory structure similar to:

com
|____oracle
| |____ojdbc6
| | |____main
| | | |____module.xml
| | | |____ojdbc6.jar

and module.xml contains:

<module xmlns="urn:jboss:module:1.0" name="com.oracle.ojdbc6">
  <resources>
    <resource-root path="ojdbc6.jar"/>
  </resources>
  <dependencies>
    <module name="javax.api"/>
    <module name="javax.transaction.api"/>
  </dependencies>
</module>
