Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V7.0 * * * **************************************************************** * PROBLEM DESCRIPTION: The Session Initiation Protocol (SIP) * * router was incorrectly comparing the * * server types upon start up. * * * **************************************************************** * RECOMMENDATION: * **************************************************************** The SIP router was not looking for the correct server type name and thought it should have started the inbound channel chains.
Problem conclusion
The SIP router now correctly looks for the correct server type name for the Deployment Manager and Node Agent and does not try to start any inbound channel chain groups. APAR PM08127 is currently targeted for inclusion in Service Level (Fix Pack) 7.0.0.9 of WebSphere Application Server V7.0. Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
