Add support for datasource failover ----------------------------------- Key: JBAS-1391 URL: http://jira.jboss.com/jira/browse/JBAS-1391 Project: JBoss Application Server Type: Feature Request Components: JCA service Versions: JBossAS-4.0.1 Final, JBossAS-3.2.7 Final Reporter: Scott M Stark Assigned to: Scott M Stark
The change to org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory is easier than org.jboss.resource.adapter.jdbc.xa.XAManagedConnectionFactory In LocalManagedConnectionFactory add a property "delimiter" which when present will parse the connectionURL into multiple urls. In XAManagedConnectionFactory you will also need a property to identify which of the xaProps needs to be parsed for mulitple urls. i.e. you need to identify which property contains the server to contact. In both cases, if createManagedConnection fails for the first url, replace it with the second url, and try again until all urls are exhausted. Of course, you can get clever and remember which urls are currently failing and try the non failing urls first, And also if the db is replicating, you might want it to "load balance" connections across the urls? Also, this design does not allow for using different properties with different db servers, e.g. user and password might change across the servers. It also doesn't enforce that only connections from one connectionURL (db server) are in the pool at the same time in the event the db is not replicating. If you are going to do this, I would suggest you subclass/replicate the managed connection factories and create separate rars so we can mark them as experimental. xxxxxxxxxxxxxxxxxxxxxxxx Adrian Brock Director of Support Back Office JBoss Inc. xxxxxxxxxxxxxxxxxxxxxxxx -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - If you want more information on JIRA, or have a bug to report see: http://www.atlassian.com/software/jira ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
