Error description
When using a Java monitoring software that allows you to see the time spent in methods and exceptions thrown, org.omg.CORBA.BAD_PARAM exceptions are seen for ORB requests that are not for eXtreme Scale.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: WebSphere eXtreme Scale users who * * integrate WebSphere Application Server and * * make ORB requests that are not for * * eXtreme Scale; for example, EJB requests. * **************************************************************** * PROBLEM DESCRIPTION: When an ORB request or reply does not * * contain a requested service context, * * an org.omg.CORBA.PARAM exception is * * thrown. * **************************************************************** * RECOMMENDATION: * **************************************************************** WebSphere eXtreme Scale was designed for flexibility, which includes using non-IBM ORBs. As such, the ORB code in eXtreme Scale uses the standard CORBA APIs that throw an org.omg.CORBA.BAD_PARAM exception when a request or reply does not contain the requested eXtreme Scale service context for requests that are not for eXtreme Scale. These exceptions are benign because eXtreme Scale catches the exception and does not treat the request as an eXtreme Scale request. Java monitoring software can show that these exceptions cause up to a five to ten percent performance impact on these ORB requests that are not for eXtreme Scale. The eXtreme Scale software was updated to conditionally use the optimized IBM ORB function that does not throw an exception when we detect that the ORB is an IBM ORB. The optimized function of the IBM ORB is used by other WebSphere Application Server components that have service context that they attach to ORB requests.
Problem conclusion
An interim fix is available for this APAR for the V7.1.1.1, V8.5.0.3, and V8.6.0.4 releases.
