Rman cloning when both directory and db name are same.

WHEN BOTH DIRECTORY AND DB NAME ARE SAME.

PRE - STEPS

I. DATABASE IN ARCHIVE LOG MODE.

II. CONTROL FILE AUTO BACKUP ON.

STEPS TO BE PERFORMED ON TARGET ( SOURCE ) DATABASE :

DB NAME : TARG

1. TAKE BACKUP OF DATABASE

RMAN > backup database plus archivelog;

2. ONCE BACKUP DONE COPY BACKUP-PIECES TO AUXILIARY (DESTINATION ) DATABASE USING LINUX

COMMAND scp.

RMAN > list backup; (Shows list of back pieces )

RMAN > list backup of controlfile; ( shows control file backup piece loction )

3. COPY PARAMETER FILE (init file) TO AUXILIARY ( DESTINATION ) DATABASE.

$ scp initTARG [email protected].***:$ORACLE_HOME/dbs

4. ISSUE BELOW COMMANDS ON TARGET ( SOURCE ) DATABASE FOR FOR DATAFILES, REDOLOG FILES, CONTROL

FILES LOCATIONS.

SQL> select file_name from dba_data_files;

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

$ export ORACLE_SID=TARG

$ sqlplus '/as sysdba'

[oracle@Dup dbs]$ sqlplus '/as sysdba'
