    Upgrade Oracle Apps 11i ( 11.5.10.2 ) to 12.1.1 on AIX Questions

    584609
      hi all,

      i have few questions regarding the above subject

      Q1 : during the upgrade the installer asks to input Oracle Database owner and BASE directory , and port pool and ...etc

      is it a new location with new user or it should be the same of 11i BASE directory and the same ports

      Q2 : once i'm done with the code tree ( first step ) how we can link the R12 instance with the exisiting database 11g ( 11.2.0.2 )?

      brief explanation would be great

      Regards,
      Samer

          It should be done with the same Application owner, and the base can be changed if you want. But the port pool must be same.

          Q2 : once i'm done with the code tree ( first step ) how we can link the R12 instance with the exisiting database 11g ( 11.2.0.2 )?

          At the time of upgrade, it asks you the database details. Here you have to put your existing database details like hostname, port etc.


          Thanks

            thanks mate ,

            do i need to bring down dbTier and appsTier while installing the code tree?

            when the system needs to be down and in which step?

            1- plan for the upgrade ( code tree )....> the system should be down or not? which part?

            2- the real upgrade ? ( confgiure the upgraded code tree ) -->the system should be down or not? which part?

            thanks

              No.
              when the system needs to be down and in which step?

              Step "Run Rapid Install (required)" -- http://docs.oracle.com/cd/E18727_01/doc.121/e16342/T527285T527359.htm

              You do not need to bring the 11i application or database down.
              2- the real upgrade ? ( confgiure the upgraded code tree ) -->the system should be down or not? which part?
              The application should be down but NOT the database. The database remains open all the time when you upgrade from 11i to R12.

              Perform the Upgrade -- http://docs.oracle.com/cd/E18727_01/doc.121/e16342/T527285T527419.htm#5236325

              Configure and start server processes (required) -- http://docs.oracle.com/cd/E18727_01/doc.121/e16342/T527285T527419.htm#5236559

                    The Base directory field defaults to a sample directory name, using the operating system syntax for the machine where you started the Rapid Install wizard. This directory is the top-level directory that Rapid Install uses to derive the mount points associated with the RDBMS.

                      Please refer to the upgrade doc (link referenced above), it shows all the steps you need to follow.
