RE: How do I restore an old RMAN backup

Hi

I think it will definately test the state of the backup files. If you can restore to a different machine I guess you can restore to original location.
To be honest I have 3 tiny test databases (TEST1/2/3) that I've used to try all sorts of different backup and restore options and ended up with a nice set of test scripts (Examples that I missed in almost all the documentation). As far as implementing it in production, I've written the implementation plan but do not get the resources to testand implement at the moment.

Jack - Thanks for including your script. Very helpful for RMAN novices like myself. Would you consider this a valid disaster recovery test? Thanks.

Hi

Try

Set until time clause in the restore (there is an issue with this I believe)

This ,I guess, will force Rman to look for the appropriate backup.

>From my test scripts:

rman <<EOF
connect target rman/rman_oracledba_at_test2 connect catalog rman/rman_oracledba_at_test1 connect auxiliary sys/oracledba_at_test3
run {
resync catalog;
allocate auxiliary channel d1 type disk; allocate auxiliary channel d2 type disk;

# set until time "to_date('2002-01-29:15:16:53','yyyy-mm-dd:hh24:mi:ss')"
# set until time "to_date('30-JAN-2002 10:50:00','dd-mon-YYYY HH24:MI:SS')"
# set until time '31-JAN-2002 10:51:00'

set until time 'sysdate-1/96';
# set until scn = 155534
set newname for datafile '/data/oracle8/TEST2/systemTEST2.dbf' TO
'/data/oracle8/TEST3/systemTEST3.dbf';

set newname for datafile '/data/oracle8/TEST2/rbsTEST2.dbf' TO
'/data/oracle8/TEST3/rbsTEST3.dbf';

set newname for datafile '/data/oracle8/TEST2/tempTEST2.dbf' TO
'/data/oracle8/TEST3/tempTEST3.dbf';

set newname for datafile '/data/oracle8/TEST2/dataTEST2.dbf' TO
'/data/oracle8/TEST3/dataTEST3.dbf';

set newname for datafile '/data/oracle8//TEST2/tempTEST202.dbf' TO
'/data/oracle8//TEST3/tempTEST302.dbf';

sql 'alter system switch logfile';
duplicate target database to test3
LOGFILE
'/data/oracle8/TEST3/redoTEST301.log' size 1M,
'/data/oracle8/TEST3/redoTEST302.log' size 1M,
'/data/oracle8/TEST3/redoTEST303.log' size 1M;
}

Hi!

I want to put a copy of the production database onto a test box. The deal is that I need to use the full backup taken on August 1st. How do I tell RMAN not to restore from the last backup, but use the one that was created almost two weeks ago?

This is 8.1.7 on Solaris.

Thanks,
Helmut
