backup and restore
Posted on 2012-12-31
I have a database named orcl
I backup the data using rman ...
the backup is in this locationn
[oracle@wtu flash_recovery_area]$ cd orcl/
[oracle@wtu orcl]$ ls
control02.ctl
[oracle@wtu orcl]$ cd ..
[oracle@wtu flash_recovery_area]$ cd ORCL/
[oracle@wtu ORCL]$ ls
archivelog autobackup backupset flashback onlinelog
[oracle@wtu ORCL]$ cd backupset/
[oracle@wtu backupset]$ ls
2012_10_17 2012_10_29 2012_12_31
[oracle@wtu backupset]$ cd 2012_12_31/
[oracle@wtu 2012_12_31]$ ls

o1_mf_annnn_TAG20121231T02
o1_mf_nnndf_TAG20121231T02
and then I deleted the
[oracle@wtu oradata]$ cd orcl/
[oracle@wtu orcl]$ ls
control01.ctl redo01.log redo03.log system01.dbf undotbs01.dbf
example01.dbf redo02.log sysaux01.dbf temp01.dbf users01.dbf
[oracle@wtu orcl]$ rm -rf *
Then I tried to connect rman to restore and recovery..
Meanwhile i shutdown the database....
SQL> shutdown immediate

ORA-00202: control file: '/u01/app/oracle/oradata/o
ORA-27041: unable to open file

Then I tried to connect rman for restore and recovery..
But is shows the error ....

I would suggest looking at the documentation. This should be a helpful link:
http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmadvre.htm#i1006453
This link takes you to disaster recovery, which is more or less the scenario that you are trying to test. The reason that you are getting an error is that you have deleted the control file and that needs to be restored first.

do a "shutdown abort"
then do a "startup nomount"
you then need to restore the controlfile from the backup;
then you can restore the database

there are three backup pieces in the above folder...

restore controlfile from ' ' which one I will give for controlfile
which one I will give for spfile.
which one for redo log

which script did you use to backup the database with - did you specify that you wanted to back up the controlfile - what is in the autobackup folder ?
try:
rman target=/
restore controlfile from autobackup
try:
rman target=/
restore controlfile from autobackup
I did until this

ok - thats restored your controlfie which is great;
all you need to do now is to restore the database;
in rman issue: "restore database"
after that issue "recover database"
thats should do it!

thats should do it!
rememeber if your controlfile was the last thing you backed up after the database your fine - however if its the first thing you backed up you will need to register your backup pieces in rman using:
CATALOG BACKUPPIECE '/2012_12_31//o1_mf_annnn_
do this for each piece
CATALOG BACKUPPIECE '/2012_12_31//o1_mf_annnn_
do this for each piece
After that this is the problem..
