DSRA0302E: XAException. Error code: XAER_RMERR (-3). Exception:

It's been published in several places, I guess but for the sake of simplicity:

Websphere 8.5, Oracle 11.2, datasource and transactions. You start your WAS server and see this in the logs:

the key is:

at oracle.jdbc.xa.OracleXAResource.recover(OracleXAResource.java:709)

as there are some pending, unrecoverable transaction in the transaction log. there are two ways to deal with it:
- start your server, nevermind your business applications not working, go to console, Application servers > server1 > Transaction service, then to Runtime tab and there you can see some options to manually manage pending troublesome transactions:

- or alternate: stop server, go to <profileroot>/tranlog/(respective path)/tranlog & partnerlog, delete tranlog and partnerlog files. start server.

Now, the way no. 2 is advisable for development systems, where any data loss is irrelevant. For production, proceed with care and try way no.1 first. Should it fail, go hardcore and delete tranlog.
Good luck.
