Download as docx, pdf0 likes64 views
1. The document describes steps to duplicate a database where the source and destination database have the same name. It involves taking a backup of the source database, copying files to the destination, and using RMAN to restore and recover the database. 2. Key steps include making the directory structures the same on source and destination, starting the destination database in nomount mode, restoring the control file and datafiles, recovering changes, and opening the database. 3. The destination database is verified by checking the locations of datafiles, control files and redo logs.
![SQL> select name from v$controlfile;
SQL> select member from v$logfile;
STEPS TO BE PERFORMED ON AUXILIARY (DESTINATION ) DATABASE.:
DB NAME : TARG
5. MAKE DIRECTORY STRUCTURE SAME AS TARGET ( SOURCE ) ON AUXILIARY ( DESTINATION ) SERVER FOR
DATAFILES, REDOLOG FILES, CONTROL FILES.
FOR DIRECTORY STRUCTURE REFER STEP 4.
6. START AUXILIARY ( DESTINATION ) DATABASE IN NOMOUNT MODE
