CLONING RMAN FROM A BACKUP IN 10G

[oracle@boss ~]$ cd rmanbackup/ [oracle@boss rmanbackup]$ ls 01nsnp5o_1_1 02nsnp5r_1_1 03nsnp6k_1_1 control_filebkc-1965345038-20121213-01 [oracle@boss rmanbackup]$ vi control_filebkc-1965345038-20121213-01

Now go down and copy the pfile from the backup piece.

Copy the pfile from the backup piece and past it inthe clone db.

[oracle@boss ~]$ mkdir db6 [oracle@boss ~]$ cd db6 [oracle@boss db6]$ mkdir admin oradata [oracle@boss db6]$ cd admin/ [oracle@boss admin]$ mkdir pfile bdump cdump udump create [oracle@boss admin]$ cd pfile/ [oracle@boss pfile]$ vi initdb6.ora [oracle@boss pfile]$ cd ../../oradata/ [oracle@boss oradata]$ mkdir data log ctrl arch [oracle@boss oradata]$ [oracle@boss oradata]$ ls arch ctrl data log [oracle@boss oradata]$

Open the pfile add the db_unique_name=db6. Change the db_name as same as the source db background_dump_dest='/home/oracle/db6/admin/bdump/' compatible='10.2.0' control_files='/home/oracle/db6/oradata/ctrl/control1.ctrl' core_dump_dest='/home/oracle/db6/admin/cdump/' db_name='db2'-- snap db db_unique_name=db6-- clone db pga_aggregate_target=500m sga_target=800m undo_management='auto' undo_tablespace='undo' user_dump_dest='/home/oracle/db6/admin/udump/'
