Now i have deleted my all controlfile and spfile/Pfile from the database. So how can i recover my SP file and control file? i do not have autobackup on of SPfile / Controlfile.
My oracle backup via Netbackup failing with error 6 (Netbackup) and i have checked the logs please find the RMAN log file as well.

I'm going to backup this un-maintained Oracle 11g server in my office. I'm being told it's never been backed up and extremely critical to our success so tomorrow I'll be performing my 1st backup of the database using RMAN. My question is if I connect to the Oracle 11g database and run the:
[oracle@db1 ~]$ rman target=/

RMAN> shutdown immediate
using target database control file instead of recovery catalog
database closed
database dismounted
Oracle instance shut down
BACKUP DATABASET FORMAT �/oracle/u01/app/oracle/backup/%d-%T-%s-%P�;
My question is the above sufficient for a safe full backup? We only have the one single target database called 'cqdb' which houses several schemas. Can you tell me if this is correct? I've shut the database down so it's in a cold state so I don't think I need to configure the FRA (Flash / Fast Recovery Area) but I honestly don't know. This is my 2nd time on a Oracle DBMS.
What about the 'archivelog' files? Do I back those up? Do I need them in case a recovery? Also what about the 'controlfile'? Do I need to back those up as well as the mentioned above?
I installed 11g on linux rhel 5.2 by manually. now databse is ok . But some Schema HR , Scott , Oe are not come. but database fully work. ok.
Now i am trying to connect Rman.
export ORACLE_SID=ORCL
rman target /
then I have a error that SYS.DBMS_BACKUP_RESTORE is not found.
but sql> desc sys.dbms_backup_restore package is available.
which script are run to solve it , because only catalog.sql and cataproc.sql script are run in installing of oracle 11g manually instalation.
My production database is about 900 GB in size but the actual data in our database is only approx 600Gb it means 300GB is a deleted data and not fragmented, as per my understanding the best way to resolve fragmentation is Import/Export but we can go for this option because its a very time taking process.
We are taking full database backup using RMAN every week and also going to upgrade our production database from Oracle SE to Oracle EE edition using the same full database RMAN backup, as i know Rman is also not backup of those blocks which not containing any data , it means if we will use Rman full backup to setup our new EE database it will only 600GB of data not 900GB or there is only Export/Import to remove fragmentation.
is there a way to find-out how many GB completed in x time-frame by RMAN on oracle 11.2.0.2.

On database A we have full backups (not incrementals) every morning at 3:00 AM including archive logs. When I query rman (list backup) I see the full at 3 AM (in two backup pieces, each in its own backup set) as well as the backup piece containing archive logs through 9:00 AM.
Due to a data issue at around 10AM, I attempted to do an incomplete recovery to 8:00 AM (data loss is not a concern) - once this was complete I opened the database with resetlogs.
I subsequently discovered that the data issue had occurred closer to 6:00 AM and I am now trying to restore to 5:00 AM. This is failing with the 'UNTIL TIME IS BEFORE RESETLOGS' error. I read up on incarnations, but my previous incarnation is from November, and when I reset the database to this incarnation and attempt a restore I get datafile 1 (2,3) is not available for restore.
how do I basically just restore the full 3:00 AM backup and apply the archive logs through 5:00 AM? Do I need to do a recover until cancel or something? And should I reset the incarnation?
able to utilize "RMAN Restore of Backups as Part of a Database Upgrade [ID 790559.1]" and duplicate an 11.1 PRD DB to another server that only has the 11.2 software. When I attempted this, I got an error since the target DB is a earlier version than the rman client - "RMAN-06429: TARGET database is not compatible with this version of RMAN".
I tried to avoid connecting to the target database & just use the following syntax (duplicate 'prd' DBID 123456789 to 'dev') to let rman know about the backups it would need from NetBackup.
That also got an error - RMAN-01009: syntax error: found "single-quoted-string": expecting one of: "database, for, target, to". I tried other variations, but also got errors.
I may try this from a disk based backup, but have to wait to get a large enough NFS mount to be able to complete this. The following syntax was in the 11.2 rman docs:
DUPLICATE DATABASE 'PROD' dbid 8675309 to 'TEST'
UNTIL TIME "to_date('11/01/2007', 'MM/DD/YYYY')"
BACKUP LOCATION '/backups' NOFILENAMECHECK
PFILE='?/dbs/inittest.ora' db_file_name_convert='prod','test';
Our goal is to not have to install the 11.1 software on our new servers. Also, trying to avoid restoring with the same name & then renaming the DB so that ASM would have multiple directories for the DB.

I am not using RMAN. How to recover payrol.slip table ?
Given facts:
rman is used to backup database A to disk
rman is used to put those disk backups to tape
rman is used to duplicate database A to database B on another host
the duplicate process worked fine before we started testing encryption
the duplicate process worked fine with database A having an encrypted column in one table in a non-encrypted tablespace
Now, database A has an encrypted tablespace with nothing currently in it. The duplicate process now ultimately fails with ORA-19913, unable to decrypt backup.
I am not using encrypted backups, not specifying encrypt or decrypt anywhere in the duplication process. The only thing that is encrypted is the one tablespace in database A. I have the same wallet files on Host A (database A) and Host B (database B). Wallets are open. So why does the duplication process fail because the backup cannot be decrypted?
We are upgrading from oracle 9.2.0.8 to 11g r2, and both are Standard Edition database. The database is part of a product that runs on a customer site, and won't get bigger than 50 GB. It runs in archive mode, and our backup script does a hot backup every night, plus copying the archive logs, redos, controlfiles, etc. We save 2 entire backups - from the last night plus the night before last. Then there's a tape backup that saves the backed-up files to an off-server location.
This architecture has allowed us to recover our customer's data from many odd occurrences at customer sites (power loss during a hot backup, corrupt controlfiles/datafiles/archivelogs). My question is, given that we are running the Standard Edition database, which doesn't have most of the useful RMAN features, is it worth it to switch to RMAN?
I took an Oracle Backup and Recovery class and posed this question to the instructor, and the response was, it would be better to use RMAN over a manual user backup script. Our backup script is pretty battle-hardened - is that the best reason?
I started restoring and testing all the backups. So far I did good and I wanted to restore and test in different host. I couldn't find any online documentation regarding restore full back up in a new different server (With same OS and same version of Oracle) without RMAN catalog database.

View 6 Replies View RelatedThe customer wants the RMAN recovery catalog database to be highly available so that none of the RMAN database backup jobs are impacted at the time of taking the database backups. There are are 200+ databases running on OEL, RHEL and Windows. So we planned to host the recovery catalog database on Oracle Active DataGuard 11.2.0.1 Enterprise Edition on RedHat EL 5.8 version on two physical servers.
The Primary Instance will be in one server in the Primary DC and the Standby Instance will be on another server in another DC. Also all the database datafiles are hosted in ASM Diskgroups on SAN (DATA, FRA, REDO, ARCH diskgroups). Are there any specific RPM/patch/OS user custom/specific settings or configurations needed..?

I have some problem while restore the database in separate environment.
This My backup policy and retention
I have monthly full database backup on march the backup started 2nd march 15:31 and completed at 03 march 11:12 AM retention period 3 years
We have ADHOC ARCHIVE backup which will run for certain conditions if the file system threshold reach 80%
In between the monthly backup the ADHOC ARCHIVE jobs has executed from 03Mar2011 00:00 to 03Mar2011 05:14 this retention period is 30 days
So while restore the database with monthly backup i can't able to recover the the datafiles due to adhoc archive files are missing.
We are cloning a database, but using the restore method ( version 11.1.0.7). The source and destination path are different. As we are using the source controlfile, before restoration SET new name inside the run block is the way to change the path.
I was just wondering, if there is any other way to do it. Because, we have around 1000 datafiles, and dont want write everything in the run block. Also, this goes from Non-ASM to ASM. I tried DB_FILE_NAME_CONVERT, but it seems to be not working.
run
{
Set newname for datafile 1 to '+DATA_DG1';
Set newname for datafile 2 to '+DATA_DG1';
Set newname for datafile 3 to '+DATA_DG1';
Set newname for datafile 4 to '+DATA_DG1';
restore database;
switch datafile all;
}
I would like to know how to migrate the database from linux to windows using RMAN.

View 1 Replies View Relatedcreate a backupset, tag it, and restore it. You could say that what I'm trying to achieve is analogous to a flashback, but rather than specifying a timestamp, I'd like to simply restore the entire db to exactly what was there when the tagged backup was taken.Here is the RMAN script I am using for the backup procedure:
run {
#allocate channels
#ALLOCATE CHANNEL FOR DEVICE TYPE DISK;
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
#backup database
BACKUP FULL DATABASE TAG='latest' PLUS ARCHIVELOG TAG='latest' DELETE INPUT;
[code]....
I'd like to take these backups in online mode, and I've tried taking both a consistent and inconsistent backup modifying the above script.Additionally, I'm using the following restore script to try to revert the database to the state when the backup set was taken (and am testing the data being restored by deleting some data entries after taking the backup):
run {
#shutdown db (should be done already)
SHUTDOWN IMMEDIATE;
#mount db
STARTUP NOMOUNT;
#show RMAN settings
SHOW ALL;
[code]...
When performing the restore, I dont see the data backed up, rather I see the latest data still in the database. why the state of the db is not getting reverted to the backupset with tag='latest'.Finally, here below I've listed the rman settings for reference:
RMAN> show all;
RMAN configuration parameters for database with db_unique_name ### are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default

I have Oracle database.I take rman backup everyday.Also I set a scheduled backup script.But scheduled backup size is 166MB,but if I take manual rman backup(rman>backup database) this backup size will 2.8GB.This backup isn't incremental backup.
I wrote 3 batch script.Finally this backup script call
backup script:
run
{
backup database plus archivelog delete input format 'C:\db_11g_backup\backup\oracle_scheduled_backup\backups\%d_%t_%s.rman';
[Code]...
"If no level 0 backup is available, then the behavior depends upon the compatibility mode setting. If compatibility is >=10.0.0, RMAN copies all blocks changed since the file was created, and stores the results as a level 1 backup. In other words, the SCN at the time the incremental backup is taken is the file creation SCN. If compatibility <10.0.0, RMAN generates a level 0 backup of the file contents at the time of the backup, to be consistent with the behavior in previous releases."
So yes, that's it. Even in the Oracle 11g OCP course and exam, the information given is for Oracle 9 (pre 10g). Seems like a major functional regression.
------------------------------------------------------------------------------------------------------------------------------------------------
Original problem.
Am I not understanding something about rman????
Using oracle 10g standard edition and rman.
No existing backups.
When I run repeated level 1 cumulative incrementals, the appear to back up everything (like a level 0 would).
My understanding is that if a level 1 is run w/o an existing level 0 backup, it will generate a level 0 backup.
All subsequent level 1 backups should be level 1's as expected.
If I explicitly generate an level 0, followed by level 1's it all works as expected.
I am determining what got backed up by the size of the resulting save sets.
Do I have to do an explicit level 0 and then explicit level 1's? I thought not.
How after a re-catalog of an archivelog, RMAN knows that the archivelog will be needed and in the right order?
If the re-catalog and subsequent crosscheck has changed the path of the archivelog will RMAN ignore the path and just recognize the archivelog name and format?
