When we run the dispatcher service from clusterDispatchergo.bat, it gives the message: "SAP J2EE Engine version 6.20 patch level 87975.20(PL28) is starting". When we run the J2EE instance dispatcher service from usrsapj2eej2ee_00 clusterdispatchergo.bat, it gives the message: "SAP J2EE Engine version 6.20 patch level 42064.20(PL10) is starting".
Are the above J2EE engine patch levels ok? If not, how do we install or upgrade dispatcher service patch level of SAP J2EE engine instance (usrsapj2eej2ee_00clusterdispatchergo.bat)?
That is a common question, and SAP has mentioned mitigate measures for that issue. You can find a solution in OSS note 724452.
