Hi,
Recently we had a hardware issue leaving some systems irreparable.
Our Solution Manager system, SolMan 7.1, is one of them. We are on Windows and SQL Server platform and we have backups for Data Drive and USR.
I have read that we can build a Dual-stack system if we have DB and USR backups in place. But unable to find any information on how to bring back Java with USR backup alone.
We will perform DB refresh via SQL Server 'Attach DB' method for the ABAP part, can anyone advise on how to build back Java part of our solman system.
Thanks,
Naga
Hi All,
This is what i did to resolve the issue. (Cannot guarantee that i have resolved the issue completely though, as Java is from a new installation. Hope we do not encounter many issues while users start working)
1. Installed a new solution manager system with same SID/Hostname/IP
2.DB refresh performed using Detach/Attach method on SQL server and post SAP scripts run (Note 1294762)
3. Few issues occurred which were corrected (regular Basis like issue)
And we are back!
Note that this method is workable only when your current Solution Manager system is used where Java system usage is minimal to nil
Thanks,
Naga

Hi
you can use standard System copy (export / import ) for the same dual stack
and more over if you have backup of
/usr - Directory and backup of DB
yes you can get back the java system with simple restore.
Restore the db . copy Files from /usr/ directory backup with exact directory structure . and yes Java system can be started

Hi Dishant,
Thanks for your response.
Can you be a little more specific. Export/Import is not an option for me now, the system is broke, and all that we have is Data files intact and USR folder structure backup.
So, are you telling me:
1. Build a new Solman 7.1 system
2. Detach new DB and Attach DB from backup of datafiles
3. Remove new USR, and restore old USR from backup
Will that be it? And will i have a consistent system as earlier?
Let me tell once again, i do not have an option to export using standard system copy method, because old system has already gone for a toss.
I will have to take steps based on possibilities of building system with available backups. So, will just above 3 steps work?
Thanks again!

Naga
Thanks again!
And sorry for asking the same question again . . .
But is it just the 3 steps i mentioned, when you say restore.
My problem here is, we also do not have a OS backup in place!! So am asking for clarity.
With available backups, i can only perform mentioned 3 steps. If that can solve the problem, nothing like it. But if there has to be any further steps then i don't think i have resources to have the system built.
So if you have already performed such a restore, then please be a little more specific, preferably with step-by-step instructions. (I think this kind of restore would work on a Unix environment, but want to be sure if it works on Windows too, considering registry and all)
Naga
As this is dual stack you will not be able to start the Java stack with just the database backup. You will need the file system backup as well especially the /usr/sap/SID which has the Java application data and the configuration files.
On Unix a simple file system restore of the SAP file systems will work without an installation of SAP and database software but on Windows I am not sure whether it helps as there are registry entries as well. In that case you are most likely going for a fresh installation.

Hi Naga,
I believe you should use standard system copy method for building new system, for both ABAP and JAVA.
