    change DBID

    user522961
      Hi,
      on 11g R2 I have some manually copied databases. I back up them in nocatalog mode. Then in controlfiles.
      I heard about DBID and then I looked at documentation that says :
       
      
      Because Recovery Manager (RMAN) distinguishes databases by DBID, you could not register a seed database and a manually copied database together in the same RMAN repository. 
      Then can we say DBID is not a concern/problem for me because I do not have a RMAN repository and it is not necessary to change DBID of copied databases ?

      Thank you.

          it depends.

          answer depends upon what you are going to restore where.

          DBID must be unique on single system.

            thank you. I want to restore on the same physical server.
