Dear Friends

We are planning to Build a BW System for Test Purpose , the solution we want to follow is the SYstem Rename Concept.

Can we Do it using  the OS backup Restore using the TAR mechanisam , and then proceed with this Rename ?

and as per my understanding using the guide we need to create a file system such as /usr/sap/SID--old

and /usr/sap/SID--new.

Apart from this no other file systems need to be created extra .

Can some one guide me in this procedure.

Regards

Sandeep

Absolutely. On Unix/Linux platforms you can copy the file systems from the source and create the target system on the new host. You will need to create the file systems /sapmnt/SID and /usr/sap/SID on the target server and copy the contents of these filesystems from the source server. If there is a change in the SID then you will just recreate the symbolic links. You will also need to modify the SAP profiles located at /sapmnt/SID/profile with the correct hostname and SID and port/instance numbers, add the /etc/services with SAP services. You will also need to create the OS users <SID>adm and ora<SID> (if the DB is Oracle) and copy the .sh and .csh files from the source to the target and modify them.

Hi Sandeep,

As you've already marked your thread as answered,so it would be difficult for other members to check updates from you on this thread in regards issue.First i request you to kindly unmark the thread as not answered to get more support or responses from other SCN experts too.

Anyways for the issue could you share the sapinst log from the tmp directory as well as snap-shot for the show-stopper.

HI Sriram

I had already checked the Note

As per the Note they suggested to change as below

Solution:

  1. Search in control.xml for the following entry:
    NWDBora.prototype.setDBUserEnvironment = function(nwusers, cdroot)...
  2. Replace the following line:
    <Z2>if ( installer.onUnix() <(>&<)>& OraCom.isDbHost(nw)) {</>with the following line: <Z2>if ( installer.onUnix() <(>&<)>& OraCom.isDbHost(nw) && !nw.
    isAddinInstallation() ) {
  3. Restart Sapinst with the option "Continue old installation".

From My Control.xml

these lines had already been existing

if ( installer.onUnix() && OraCom.isDbHost(nw) && !nw.isAddinInstallation() )

  {

    var user = undefined;

    var ad = undefined;

and i restarted the sapinst , but the same issue occurs

Hi Sandeep,



UNIX only: SAP system created as copy of file system and database of source system





It mean that Tar Backup Restore Will work? just  need to confirm about this

Yes it'll work,you need to follow SAP Homogeneous system copy guides.

Hi,

As per my understandings System Rename concept,you could follow SCN docs at http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/700e1f3f-1221-3110-4dbe-ff56c6132...

&

With this you need to use SWPM for system renaming.

Hi Sandeep

1.  Is it dual stack or ABAP / JAVA only system?  If it is Dual better you can perform the Normal System copy of PRD to Test system,

2. If it is Single system your can follow the steps as mention by Rana. before starting the check the SP /patch level  and restrictions. Refer the SAP note  1619720 - System Rename for SAP Systems based on SAP NetWeaver
