Disaster recovery

[Former Member]

Hi Gurus,

I am trying to recover my SAP from an Oracle database backup onto a brand new server.

Previously in 4.7, I will restore and recover the Oracle DB. Thereafter, I will install CI from sapinst. This works fine.

Recently we had upgraded our SAP to NW7.0. I tried to install SCS, recover DB, and lastly, install CI. But this procedure failed. During CI installation, I encountered the error msg: "SecureStore files must be available on Unix". Upon checking, the global/security/data folder is empty.

Can someone advice on the correct procedure to recover SAP Netweaver to a fresh system?

Thanks,

Hi Surendra,

System copy is not quite what I am looking for. My requirement is to recover from tape. Moreover system copy cannot be scheduled and requires downtime; unlike incremental online backup that can be schedule to run online.

Hi,

I am exploring dataguard too. But currently, my priority is to restore the backup from tape.

My current recovery plan for NW7:

- Install a new SAP system. (including database content with new datafiles)

- Delete datafiles

- Restore backup files from tape

- Recover database

From the steps above, I spend many hours creating the new datafiles and eventually, these datafiles are deleted. This is such a waste. I will like to avoid generating these new datafiles, and hence archiving a shorter recovery time.

Addition info

In R3 4.7, my recovery plan is:

- Install Database application using the database CD (just the application, not the content/data)

- Restore and recover database

- Install CI using sapinst

I am able to recover my SAP system with fewer steps and within a shorter time in 4.7. These steps does not work on NW7 (error mentioned earlier in the thread).

I hope this is clear enough. Any opinions?

HI,

You don't need to recover etc ..

For DR just take a system copy and restore to new brand server then

configure DR server ..like standby controlfile,init file etc.

Read Dataguard document.

Hi,

I installed a brand new sap system. Thereafter, I restored my backup onto this new system. And it works!

But this method is not efficient. When installing the new system, a huge amount of time is spend waiting for the database to be populated. I do not need the database populated as it will be overwrite with the backup data. Is there a way to skip/reduce this lengthy process? Or is there a better method for recovery?

Hi, I think you will need Java export from time you backed up your source DB as well.

Hi Peter, my assumption is that the Java export you are referring is for system copy. But in my scenario, I am trying to simulate a disaster recovery, ie the entire server is lost; export is not possible and I am left with only the database backup on tapes. Any advice?
