Reg: SID change

Hi all,

I am going for a system refresh using BACKUP RESTORE method.

But i have some doubt, after throughing the restore command system will prompts below warning that source and target SIDs are different. After this should system automatically restores the entire source datafiles into target database or do we need to set some parameters to restore into different SID?

BR0454W Values of oracle_sid are different: current 'QAS', backup bdxrjktu.ant 'PRO'

BR0455W Value 'QAS' of oracle_sid will be used for restore

BR0454W Values of oracle_home are different: current '/oracle/QAS/920_64', backup bdxrjktu.ant '/ora

cle/PRO/920_64'

BR0455W Value '/oracle/QAS/920_64' of oracle_home will be used for restore

Regards

Nick Loy

    Hi Sergo,

    This is a system refresh method for ORACLE database.

    Ex: We can restore online/offlline backup of source system to target system. This is a normal scenario when we are going for a quality refresh.

    And in my environment i am going to restore online backup, because i cant have much time to take offline backup and restore.

    Regards

    Hi Nitin,

    Thanks for your quick resp.

    For all: Please do not understand this as SID change for existing system

    This is a quality refresh. But i want to do the same using BACKUP RESTORE method.

    Steps to do this:

    1)I will take full online backup of souce system

    2)Restore backup into target system.

    3)Perform post installation/db copy steps.

    But when performing 2nd step i have bit doubt. There SIDs should be different.

    System automatically restores source database to target or do i need to change any parameters to restore?

    This doubt after giving the command brrestore -b filename -m full

    Regards
