Change SID and Servername from a TEST System without Systemcopy

Hello,

i have here a Problem. I have a cloned TEST System. So i have to Change now the Servername and also the SID of the SAP System WITHOUT doing a Systemcopy.

I know this is NOT supportet by SAP: But this is an Testsystem. So it is no Problem for us to do it without the Support from SAP.

But i have no clue how to do this.. 😔

I always used Systemcopy to Change the SID and Servername.. But this time i have to do it without a systemcopy.

So please can you help me with this?

Oh and yes. We are running on Linux with Oracle 11.2

Kind Regards

    Hi,

    Please confirm what is your OS you are going to clone?

    If it is windows environment, you can just change the server names in the instance and default profiles.. Then that should be fine.

    If it is a Unix & Linux, then in addition to change in the instance parameter and default parameter, you also need to either change the .*.sh & .*.csh files to map the new server name.

    Rest will be fine.

    We just did a DB restore with a different name and cloned the system with a different servername .. Now the system is up and running. We changed as said before.

    Thanks and Regards,

    Vimal

    Hi Bjoern,

    It is recommended to follow SAP system copy procedure, by the test system refresh/installation operations.

    Of course, the SAP system copy procedure make it easy the copy process, but it will not make a problem, if you are not planning to upgrade on newly copied J2EE based system.

    In short, you can follow the procedure in my previous thread http://scn.sap.com/message/10320147#10320147

    Best regards,

    Hi,

    we are running on Linux and Oracle 11.2

    Thanks for your Posts. So i cannot do a Systemcopy. Because the System is already cloned. So ist here and ready to use. But first i have to Change the SID and the Servername.

    Yes i know it would be better to do a Systemcopy. But as i mentioned. The System is already cloned.

    So please can you guide me through the procedure with a up and running test System? 😊

    This would be great.

    Kind Regards

    Good Day

    As you are changing the SID of the system you will need to do a lot of modifications at the OS level.

    You will need to rename the file systems.

    Modify the environment variables for the OS users.

    Rename the OS users and create new home directories.

    Recreate all symbolic links for Oracle and SAP.

    Rename SAP profiles.

    Modify the services files (eg message server service)

    Modify Oracle Listener.

    Cheers

    RB
