Using the DBMS

Modifying dbname and dbid typically requires changes to dbname and dbid after restoring to a different machine using Rman. We can do this with the help of the NID tool under the command line. You can also invoke the API directly to implement it. This article is through Dbms_backup_restore way to modify dbname and dbid, for everyone's reference.

For dbname and dbid modifications using the Nid method, refer to: Modify DB name and dbid using the NID command

1, modify the dbid and dbname steps

2, the actual combat exercise
