I developed an application on Weblogic 11g and configured a data source to connect Oracle 11g.

When I start the application, I got an error, anyone have the ideas?

One possible cause: http://www.javamonamour.org/2012/12/xaerrmfail-resource-manager-is.html

"This might well be because your Oracle DB has hit the maximum number of processes. "

For me, restarting WebLogic (along with deleting cache, tmp files of the domain) solved the problem.
