    Hi Praveen,

    I'm not sure exactly but did you make any changes to you tnsnames.ora file? The error seems to be point to it not being able to resolve the service_name. do you possibly have two entries with the same service name or maybe one misspelled?

      Hi Praveen,

      We have faced the same problem when we migrate EP5 to EP6. After your inst. of patch sp6 the server will not start up or it will go off after 5 min. and the IIS server will be in the start position. To over come this problem we need to repair the IIS software, because when we do the SP6 the IIS related dll's are getting corrupted. For this we need to repair by running the IIS inst.

      When you start IIS inst. it will ask for wheather to do a new inst or repair. select the repair option that will make the EP5 SP6 working.
