Home -> Community -> Mailing Lists -> Oracle-L -> Re: RMAN backup and restore Q?
Hi
My problem went away when I did a startup mount of the database.
I have Rman user in TEST2 just for testing purposes (same username password on target & catalog is easier with ctrl C & ctrl V)
One more question if I may.
Do you or anybody else have an example of a very complex rman command(most of the features used) and an example of cloning a database on the same host with renaming of the log& datafiles? Documentation explains a lot but is very limited in the examples and the syntax errors are easy to make.
TIA Jack

What version of the database are you using? My info here is based on 8.1.7.
I connect to my databases as internal to do the backups. I fire up RMAN with either one of these commands:
rman target / catalog rman/rman_at_test1 (SID must be set correctly) rman target internal/pwd_at_test2 catalog rman/rman_at_test1
I'm not sure why you have an rman user in test2, unless you set up a second catalog so that you can backup your first catalog.
To test your restore, shutdown test2 and delete all the .dbf, .log, .arc, and .ctl files. Then startup nomount the test2 database. Then try this:
rman target internal/pwd_at_test2 catalog rman/rman_at_test
run {
allocate channel ch1 type disk;
restore controlfile;
alter database mount;
restore database;
recover database;
alter database open resetlogs;
}
If you did a hot backup, you may need your archivelog backups. This command backs up the archivelogs:
run
{
allocate channel ch1 type disk format '/bkup1/oracle/%d/arc_s%s_p%p_%t';
set limit channel ch1 kbytes=1000000; # Limit sets to 1 Gb.
backup archivelog until time 'sysdate-1/24' delete input;
backup archivelog from time 'sysdate-1/24';
}

Hi All,
I'm in the process of figuring out the workings of RMAN and created 2 test
databases.
TEST1 = catalog database
TEST2 = target database
I have created the catalogs and registered the database with the catalog.
I than mad a full backup of the database TEST2 (is in Archivelog mode) with the following syntax
**************************BACKUP****************************************rman <<EOF
which created the database backup OK
When I try the restore however I get ORA 19753 cannot obtain exclusive enqueue for datafile 1.
****************************RESTORE*************************************rman <<EOF
Checking the database TEST2 showed a shared MR lock in the v$lock view on all tablespaces.
What am I doing wrong here?
TIA Jack
