RMAN Restore result in defragmentation or not??
Hi All,
I have read on various Oracle support sites that Oracle 10g RMAN backup uses unused block compression technique for database backup.
What I understand from unused block compression is : It will backup only currently used data blocks and leave free blocks i.e used_MB marked in the query:
select file_name,t.file_id,t.tablespace_name, total-free used_MB from
(select file_name,file_id,tablespace_name,bytes/1024/1024 total from dba_data_files) t ,
(select file_id,tablespace_name,sum(bytes/1024/1024) free from dba_free_space
group by file_id,tablespace_name) f where t.file_id=f.file_id;
If so,whether restoring database from such a backupset will result in a database with reduced datafile frgmentation like exp/imp.
Please help DBA Gurus.

other than exp/imp and rebuilding its objects..Hi Saket,
you will need to create another tablespace and move all objects from the tablespace with the fragmented datafile/s into the newly created tablespace.

Edited by: martin.morono on Nov 8, 2012 11:49 AMThanks Levi,
I slightly modified your script to recatalog the backup pieces since they are note stored at the same location in PR and QA.
No luck. The error message is different but the result is the same... it keeps failing.

If I need a full rman restore which backups will it use?
Hello,
I have a database 11.1.0.7 with 8TB. Block change tracking is enabled.
At the weekend I take level 0 backup and during the week level 1 cumulative.
For some weeks the level 0 backup is failing, so I only have level 1 cumulative backups taken every week day with a 4 weeks old level 0 backup.
If I need a full rman restore which backups will it use? Will it be the last level 0 backup with the last level 1 cumulative?
I ask this because grid crontrol tells me that the recent level 1 backups input size is smaller than last week level 1 backups and in between I dont have any level 0 sucessfull backups. Shouldn't the input size of level 1 cumulative increase until the next level 0 backup ?
The grid reports:

Validating Backups Before Restoring Them
You can run RESTORE ... VALIDATE to test whether RMAN can restore a specific file or set of files from a backup. RMAN chooses which backups to use.
The database must be mounted or open for this command. You do not have to take datafiles offline when validating the restore of datafiles, because validation of backups of the datafiles only reads the backups and does not affect the production datafiles.
When validating files on disk or tape, RMAN reads all blocks in the backup piece or image copy. RMAN also validates offsite backups. The validation is identical to a real restore operation except that RMAN does not write output files.
You can monitor what RESTORE VALIDATE does.
Make precautions, so you do not damage the production DB!!!

RMAN restore from active database, ASM
I'm attempting to refresh a stage database from a prod database using RMAN restore from active database. Both are on ASM. After working through various hurdles, I've got one issue I'm a bit stuck on. I've got a handful of data files that do NOT have OMF names (ie MSTRDATA/mstrmdpd/datafile/gsa_indx instead of MSTRDATA/mstrmdpd/datafile/gsa_indx.351.714779777) and these are failing when I do the restore. The syntax I'm using in RMAN is as follows:
duplicate target database to dwstage
from active database
spfile parameter_value_convert 'dwprod','dwstage'
SET DB_FILE_NAME_CONVERT '+DWPROD','+DWSTAGE'
SET LOG_FILE_NAME_CONVERT '+DWPROD','+DWSTAGE';
The error message I'm getting is this:
RMAN-03009: failure of backup command on ORA_DISK_1 channel at 04/21/2011 13:26:24
ORA-17628: Oracle error 19505 returned by remote Oracle server
continuing other job steps, job failed will not be re-run
Normally from what I've seen/read this error can be traced back to needing to pre-create the directories for the controlfiles etc, but since 90% of the datafiles copied correctly...
Any suggestions as to a way around this, or am I going to be forced to restore from a backupset?This fails saying that "ORA-12528: TNS:listener: all appropriate instances are blocking new connections" which is quite normal given that the listener is havig a handle in BLOCKED state for this AUXDB as it is in NOMOUNT state.
Could you please help me on how to proceed?
One option can be to create the controlfile manually and mount the instance before doing the duplicate. I hope Rman can continue from there.
Another option is to go for backup based duplicate.
Is there any other way to go?
Provide static registration on AUXILIARY side for your auxiliary instance and try again.For example change listener.ora file as
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = AUXDB)
(ORACLE_HOME = <your oracle home>)
(SID_NAME = AUXDB)
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = <auxiliary host/ip>)(PORT = 1521))
)And restart listener on auxiliary host then try again -

Rman restoration hangs with no errors
Hi,
Platform:solaris 10
oracle version:oracle 10g
I am restoring the backup from tape using RMAN.
iWe have production instances in /data1 to /data11; it is connected to TAPE through fibre cable with the speed of 256MBS/sec.
Our restoration is /aux_data01 to /aux_data11 in the same server.( fairport80)
But our restoration takes very long time. To restore 900 GB is has taken 42 hrs.
a) During the validation it has not give any error.
b) During restoration also it has not give any error (till to time)
Last update in the restoration log was today morning at 2:00 am. There after the restoration was in stale. It seems that it does not processing. Please assist me.
We are restoring the database as of 16-oct-2007.
As of 16-oct-2007 the database size was 1,763GB. It has restored 1742GB, There after no progress at all. (From 2am today)
Validate.
During validate it has not given any error
Restoration.
During the restoration has not thrown any error at all. But no progress after 24-oct-2007 2:00 am onwards.

Conclusion
Last time in 30Hrs we hit an error. but now after 84 hrs it is stale.
Can anyone help in this please

Does RMAN restore from 11.2.0.3 to 11.1.0.7?
Hi Team,
Interesting point is here, source is on 11.2.0.3 and somehow we missed 11.2.0 home on target (my team mate forgot to built new 11.2.0.3 home - we have 11.1.0 home), not sure how this rman restored/recovered with no issues on target even it has compatibility change (controlfile restore itself should fail).
Source is 11.2.0.3 and target is 11.1.0.7, presently the instance up and running with no issues, but we decided to re build with 11.2.0.3 home
Any hints? Please advice, I am curious about this functionality how did this happen! J
Thanks,
VenkatSee Oracle Support Note "Frequently Asked Questions about Restoring Or Duplicating Between Different Versions And Platforms (Doc ID 369644.1)" . Particularly Question 5.
You need to run the Downgrade procedures to downgrade a database from 11.2 to 11.1

Can rman restore tablespace to a different tablespace name?
Hi all,
I was wondering that can RMAN restore a tablespace to a different name tablespace in the same instance? I have the full backup by RMAN, I wonder I can do that or not? Any helps would be greatly appreciated. Thank you.
Rich,Hi,
a tablespace is not necessarily a logical space to separate schema objects from one another (could be, but not necessarily, depends on your object distribution).
So what you need is: export your original user schema with the exp utility
then import this dump into another user schema with the imp tool (fromuser=old touser=new)
BEFORE you create the new user and you give it a different default tablespace. If you like to really separate the objects in tablespaces (like for transportable tablespaces) you may deny access to any of the tablespaces of old user to the new user. That makes sure data is not erroneously loaded in the old tablespaces.
Read the docs to understand this clearly if you like. -

Impact of Rman restore on test server.
Hi,
I am working on oracle 10g on linux 64 bit
I have rman backup from production database. Name and SID of production database is Prod1 and i want to to check this RMAN backup after restoring it on the other test server (VMDB) for Disaster recovery.
Now problem is that, i want to test it for DR, where i only need to run a script to restore and recover a database at the time of disaster in production site.
My disaster recovery site will be in different network, so i can keep the name of database and sid same as of Production but is it possible that i could install the database in test database with same db name and same sid as of Production when Test and Production database are in same network.
What will be the steps if i want to have a single script to restore database to new server. Do i need to create database with installation of Oracle on test machine or RMAN script will create database by itself.
Do i need to set same dbid as of production in test database before restore. What can be the problems when i have production database running and i am restoring backup of same database on test machine with different IP address but same database name and SID and setting same DBID. I am not using catalog
I have a full backup of database +Auto backup of controlfile and spfile
Production database is being accessed by client via TOMCAT server.>
is it possible that i could install the database in test database with same db name and same sid as of Production when Test and Production database are in same network.
>Yes it is possible.
>Do i need to create database with installation of Oracle on test machine or RMAN script will create database by itself.
>
There is no need to run CREATE DATABASE. Running the right RMAN RESTORE statements will recreate database control files, datafiles and redo log files.
>What will be the steps if i want to have a single script to restore database to new server.
>
Note that in case of disaster recovery, you must make sure that RMAN backups are available from test server.
You can try to apply following example to your environment:

>
What can be the problems when i have production database running and i am restoring backup of same database on test machine with different IP address but same database name and SID and setting same DBID. I am not using catalog If you are not using RMAN catalog, risks are limited: you should take care at least:
1. that Oracle Net configuration files (tnsnames.ora) used in production are not updated
2. that any tool/script you are using to manage (monitor, backup, etc.) the test database does not interfere with the production database. -

Block corruptioin after rman restore/recovery
Thanks for taking my question!
Oracle Enterprise Edition 11.1.0.7 on Windows 2008. Using Rman on-line backups COMPRESSED.
Can anyone give me any ideas on why SYSAUX data block corruption should occur after a rman recovery?
Below is my script. Am I missing something? Should I be physically removing the redo? Any ideas welcome?
Thanks!
Kathie
rman> restore until seq = 123
recover until seq = 123
alter database open resetlogs;
Background:
I had to do a rman recovery the other day to restore our database back to the previous day. After the recovery the sysaux table became logically corrupted. I tried to fix data corruption with rman but it said it couldn't after reading thru 6 days of backups. I ended up deleting the database, recreating the database and restoring from an export takien a few hours prior.
I now have a database to test rman recovery. Database has been up and rman backups (compressed) running for several days. I tried to recover back to previouse day and again SYSAUX has logical corruption. I tried to use Rman to recover data corruption but it failed.
I deleted database and recreated it. Took several rman on-line backups (this time not compressed). Did 3rd recovery this time only a few hours back. This time everything worked - no sysaux block corruption but why? The only difference is the recovery used non compressed backups and recovery was a shorter time frame. why ???I agree the errors are not identical but I am going to stop performing compressed backups until I am sure that is not the issue.
My first two recoveries had logical block corruption and this last one without compression set had no block corruption. I performed the same recovery process for all recoveries and the big difference was the successfull recovery did not have compressed backups. I checked v$database_block_corruption and it shows no errors. I also, performed a backup and verify to double check.
The only issue I can see is below. I am hoping someone can confirm this is normal after "alter database open resetlogs". Can anyone verify that?
Thanks!

Setting recovery target incarnation to 3 -
Hello all,
I'm able to successfully restore a database's datafiles from tape to the host where the database actually runs but when I try to restore the datafiles to a completely differnt host RMAN errors out saying that it could not locate the datafile on the tape.
This is what I did....
Database Name : DEV (live database)
Host : dev_host
From the dev_host, I initiated the rman restore script (which connects to the catalog) to restore just one of DEV's datafiles and it worked. The datafile got restored to dev_host.
Let's now assume a disaster recovery scenario where dev_host becomes unusable and I have to restore the database from tape to a totally diffrent host and bring up the database. To simulate this I did the following.
Database: DEV( shell database in mount state)
Host : new_host
I just created a pfile and mounted the DEV database on the "new_host". At this time we do not have any of the DEV's datafiles on the "new_host". We need to retore them from tape. While the database was in mount state, I initiated the restore script( which connects to the catalog) from "new_host" but rman failed with the following message.
run {

Question: Can I not restore data from tape to a host other than where the database actually runs. I'm not sure why rman fails to restore data to a different host.
Do I need to set something at the database level or Media Manager level? We are using Netbackup.
Appreciate if you can give me some pointers.
Thanks for your time.Can I not restore data from tape to a host other than where the database actually runs. I'm not sure why rman fails to restore data to a different host.

You can. For that you have to use Duplicate command. You have to duplicate the database, by replicating it from the backup.
For that you have to have the same versions OS of both the prod (from which you took backup) and test (to which you are going to replicate). The auxiliary database (test) should be in nomount for this. There are tons of websites to give you step by step processes for this

Hi Guys,
Scenario:
I have a production database 10.2.0.4 running in host A. I did a full backup of the database using rman and of cause, all the archive logs.
Now in host B, i wanted to perform a restore of the database. I'm aware there's a duplicate function in RMAN and has tried it and working. However for this exercise, I wanted to test out the "restore" command. I do not want the database to be restored to the production as the database is running. Can i do this? I just have to ensure that tnsnames in host b is not pointed to the production server HOST Adbaing wrote:

RMAN restore after using catalog command
Hi:
I am on 10.2.0.3; hp-ux B.11.23 ia64.
I need to restore 2 weeks-old RMAN backup into a different database. RMAN runs at 11:00 pm each night.
Here are the steps I've taken:
1. Copied all backuppieces from tape into RMAN backup location where my RMAN process puts them (do I have to copy something else beside pieces?
I do full backup - BACKUP as compressed backupset DATABASE plus archivelog;)
2. Ran "catalog backuppiece" on every backuppiece.
3. Ran list backup to see that this backup from tape has been registered in the catalog and has "AVAILABLE" status.
4. Startup nomount on NEWDB.
5.rman sys/passwd@ORIGINALDB.
6. Ran my duplicate script (below is an extarct):
run {
connect catalog rman/passwd@RECCAT;
connect auxiliary /
set newname for datafile 1 to '/db/data2/NEWDB/system01.dbf';
set newname for datafile 2 to '/db/data2/NEWDB/undotbs01.dbf';
allocate auxiliary channel c1 type disk;
set until time "to_date('28-08-2008 22:30:00','dd-mm-yyyy hh24:mi:ss')";
duplicate target database to NEWDB
logfile
group 1 ('/db/data1/NEWDB/redo01.log','/db/data6/NEWDB/redo01_2.log') size 100M reuse,
Here is the error I am getting:
executing command: SET NEWNAME
executing command: SET NEWNAME
allocated channel: c1
channel c1: sid=333 devtype=DISK
executing command: SET until clause
Starting Duplicate Db at 10-SEP-08
datafile 1 not processed because file is offline
datafile 2 not processed because file is offline
Am I missing something?
Maybe that - my RMAN runs at 11pm so I am trying to set time at 10:30pm?
TIA.Hi Hemant:
Are you sure that you are connecting to the right instance as your >AUXILIARY ?
normally it would be
connect target /
connect catalog rman/passd@RECCAT
connect auxiliary sys/sys@NEWDBYes I am, RMAN sends a confirmation message: "connected to auxiliary NEWDB (not mounted).
I did this many times with my RMAN backup still online. The question is that now, when I brought 2-weeks old rman backup from tape, duplication does not work although RMAN lists this old backup as available after I cataloged every backup piece...Is this all I need to catalog? I don't think controlfile snapshot matters.
Anyone actually tried that? Bring old backup from tape (I do backupset), catalog it, then duplicate it into a new database? All comments greatly appreciated!
