System Copy - Refresh

[Former Member]

Hi there,

I am just about to start a system refresh from our ECC PROD system to our ECC QA.

I have been looking at the options available ( we currently use a 3rd party tool for our backups).

I have never done one of these before so please bear with me.

From what I have seen on SDN there are basically two options available to me. I'll be brief:

1) Restore the production database to the QA database from the latest offline backup

    using the brrestore command.

2) Manually copy all datafiles from PROD to QA. Create new control file with new path to QA.

    Then run recover database using backup controlfile until cancel

I suppose there is no right or wrong way. Just wondering what the pro's and con's are of each

of the above options are?

Many thanks

Andy

Hi Andy,

Please share some details regarding 3rd party backup software which you are using at your end.As in some 3rd party backup software's we've option of Redirected restore (With this option we need to change SID at 3rd party software with the SID for which we want to make copy.)

We can perform System copy with the use of offline backup and also with online backup.

Just create a trace file on the system from which you are going to use or that system (Primary) whose backup we'll use to perform restore on other.Just you need to create trace file by following command.

SQL>alter database backup controlfile to trace;

This command will create a trc file under ../saptrace dir and we need to modify the same and rename with control.sql which we need to execute on the other system to create control files.

Cheers Gaurav,

We use Commvault which in turn basically runs the BRTOOLS via the BACKINT.

I'm looking into the option they (Commvault) also provide.

Thanks
