WebAs Homogeneous System copy over existing directories

[Former Member]

Hello,

I am attempting to perform a homogeneous system copy of a NW2004s WebAS Java EP portal system using database-specific system copy with Oracle. OS is Suze 9 Linux.

On the target server, /usr/sap/<SID> and /sapmnt/<SID> exist from a previous install of NW2004 EP.

I am on the step "Preparing the Target system" and am attempting to run sapinst on the target system. It stops with a message:

"You entered the instance number 01 on host hhhhhhhh for the SCS instance. DIAGNOSIS: In the SAP system SID, an SCS instance already exists with the instance number 01 on host hhhhhhhh.

SOLUTION: Enter a different instance number. "

Questions:

Do I need to delete the old directories before I start sapinst on the target?

Or do you recommend installing the target with different instace numbers?

Thanks in advance for your advice.

Hello Judith,

since you obviously dont need the other Instance anymore (you want overwrite it anyway) you might as well delete it first.

TIP: The instruction for how to delete a SAP System are always at the very end of the installation manual.

Hello Judith,

I assume that even though you backed up your database you also used sapinst to take an export of your java stack? This is required as a lot of your java stack exists in the file system outside of the database.

For a system copy involving Java we always recommend that yu removed any existing target system. This is because technically a refresh of the java system is not possible, only a complete homogeneous system copy to a new target system.
