If you cannot log into the WebSphere Web Console with XELSYSADM and you see the above error in the Dmgr01 SystemOut.log file, here is the solution.

In the OIM transaction database you need to modify the password expire and warn dates to something in the future. Here are the SQL commands used:

update usr set usr_pwd_expire_date=’12-FEB-15′ WHERE USR_LOGIN=’XELSYSADM’;
update usr set usr_pwd_warn_date=’12-FEB-15′ WHERE USR_LOGIN=’XELSYSADM’;

commit the changes and then reset WebSphere (all nodes, and manager). You may have to kill the processes.

Another byproduct of the issue seemed to be hash dumps from the JMS queue causing the hard drive space to fill up. Scan the server for large files (especially log files) and remove them all before starting up WebSphere.
