Recovery Manager (RMAN) :: Restore From Full Backup While Incremental Lvl 0 Available

Sep 10, 2012

7 of days ago Full backup has been taken to disk due to issues with tape devices.3 days ago tape devices have been fixed and we switched to CommVault managed tape backups. CommVault calls RMAN with following command:

run {
     allocate channel ch1 type 'sbt_tape'
     PARMS="SBT_LIBRARY=/usr/local/bin/simpana/Base/libobk.so,BLKSIZE=1048576,ENV=(CV_mmsApiVsn=2,CV_channelPar=ch1,ThreadCommandLine=BACKUP -jm 45 -a 2:71 -cl 9 -ins 9 -at 22 -j 294321 -jt 294321:4:1 -bal 1 -rcp 0 -ms 1 -data -ma 89 -cn oraclehost -vm Instance001)"
     TRACE 0;
     setlimit channel ch1 maxopenfiles 8;
     backup
     incremental level = 0
     filesperset = 32
     database
     include current controlfile spfile ;
     }
     exit;

These backups done successfully.Then archivelog backup taken similar way.But when I issue RESTORE DATABASE PREVIEW SUMMARY; RMAN starts with Full backup set, though newer Incremental Level 0 ones are available.Why it does not use these newer ones?

Recovery Manager (RMAN) :: Information For List And Restore Command

May 15, 2013

Version 11.2.0.1

Control file record time = 7 days

I am not using recovery catalog

RMAN> list archivelog all;

It shows archivelogs from logsequence 179 - 206

But on my o.s I have archivelogs from log sequence 104 - 206 (I have not deleted them for long 1 month). It is not showing form 104 - 178. Since control file record time is 7 days it doesnt keep old archivelogs history.(i.e from 104-206) Hence it is showing only from 179 - 206

My question is

1)If we use rman recovery catalog will these info is maintained forever until deleted. And can i see them in list command. (i.e from 104-206)
2)If i use rman catalog then from where did rman get the information of archives and backup (for list and restore command) from catalog or from control file.

Backup & Recovery :: RMAN Restore / Recovery To Previous Cold Backups

Aug 13, 2013

My scenario is: database is in archivelog mode.

I run DLY cold backups including controlfile & archivelogs and keep 3 gens of backups and archivelogs to 3 days also. What is the correct procedure to restore back to an old cold backup. Database is backed up Mon,Tue,Wed on Thur we require to bring database back to Tuesday DLY security.

I have tried:
startup mount
restore database from tag 'DLYTUE'
recover database

( this just rolls forward on all archive logs once it restores datafiles, not getting to point to alter database open resetlogs.)

Next tried to :

recover database archivelog tag 'DLYTUE'
( same outcome )

What is the correct rman procedure including should I remove old archive logs from working OS directory ? Also need to know once I restore back and open database to TUE security how do you tidy up the archive logs and dumps which are no longer require i.e. : weds..

I have read about using the set until time option but how to I get absolute time from when cold backup completed if this is the correct procedure.

Backup & Recovery :: Finding Rman Restore And Recovery Process?

Feb 7, 2011

I have a doubt regarding the process the RMAN follows for restore and recovery of the database.

My Level 0 full backup completes on Saturdays at around 11 am after taking 8 hours (It starts at 3am).On Sunday, I ask RMAN to restore (on a different box) till Saturday 11:30 am.Then, after the restore is successful, I recover it till 11:45 am.

The recovery also goes fine and Iam able to clone to test box.

Till what time is the database restored? I assume its till 11 am since the L0 backup finishes at 11 am though I have asked it to restore till 11:30 am

During the recovery, ONLY the archives generated between Saturday 3 am and till the time i asked for recovery (Saturday 11:45 am ) are required. But, checking the recovery log file, i was surprised to see that RMAN has restored archive files starting from Friday 9:30 pm (Much before the time the Level 0 backup even started).

why does RMAN require the old archive log files.

Backup & Recovery :: RAC - RMAN Restore And Recovery To New Hosts?

Mar 13, 2012

1. My RAC (old RAC) had got a failures from one node, then there was only one existing node now.

2. I configured a RAC (new RAC) on 2 other servers, both of them (old-RAC and new-RAC) has got same OS version, platform and Oracle version release.

3. I took a full backup yesterday plus archivelog in the node of old-Rac, configure NFS in new-Rac to make the backup within remote-share NFS.

The only problem still now that I've restore/recovery/duplicated single instance, not Rac. So, may you guide me to do it?

Information:

Old-Rac & New-Rac:
+ Cluster 11g: CFS
+ Database: 2 nodes with same instance name (cbs1-cbs2)
+ Location for CRS_HOME and ORACLE_HOME: Same to be.
+ Location of archivelog: Same to be (+ARCHIVE)

Backup & Recovery :: RMAN For Channel And Parallelism?

Aug 2, 2012

whats the difference between channel and parallelism in RMAN ?

What is the Oracle recommendation for RMAN channel allocation ? I have read some were that RMAN channel allocation must be 4 times of the Server CPU -1. Say for example if there are 2 cpu in the server, then the channel allocation would be 4 * 2 -1 = 7 ?

Backup & Recovery :: RMAN-12010 / Automatic Channel Allocation Initialization Failed

Nov 15, 2011

while executing a clone script i got the below error : -

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

RMAN-06758: DB_UNIQUE_NAME is not unique in the recovery catalog

Here i understand that RMAN couldn't find which SPFILE to use to restore the target DB.

How do i check for the DB_UNIQUE_NAME in recovery catalog?

The proposed solution that i found was Use the FOR DB_UNIQUE_NAME option to specify the name of the instance whose parameter file you want to restore. how to implement this in my clone script?

Backup & Recovery :: Restore With RMAN

Feb 14, 2011

I have to test a hot rman backup on testing environment and I have some doubts.

STAGE
Server 1
production database (linux)
backup folder on cifs share windows server
Server 2
testing database (linux)

First I installed linux on same network, I gave it access to cifs backup resource, then I installed the same database version than production environment, then I create a typical database with only same database production name. Also the Linux partitions between linux servers are different.

What oracle procedure must I apply?

Backup & Recovery :: RMAN Restore Off Autobackup

Nov 1, 2013

I want to restore my database from server x to server y.

The control files on server x are named [$ORACLE_SID]_control01.ctl and [$ORACLE_SID]_control02.ctl.

We have an auto backup of the control files.

When I restore the control files on host y, (from autobackup) the restored controle files have other names: control01.ctl and control02.ctl. After the restore and recover (which goes well) the database does not start correctly.

RMAN :: Restore / Recovery From Snapshot Faster?

Aug 8, 2012

Version : 11.2 on Solaris, AIX

All our production DBs are backed up by some Hitachi tool (apparently it is called ShadowImage) . Apparently they put all the tablespaces in Backup mode and 'take a snap' . Our BAU team says this is faster.

On an event of DB Crash Is it easier to restore, recover from these 'snapshots' ? Are these snapshots much faster than RMAN ?

RMAN :: Point In Time Recovery Using Restore?

Aug 30, 2012

Oracle RDBMS 11.2.0.2.RAC and Host RHEL 5.6

My dev application team iwant to test their application, and once that is done they want to recover to point in time. In my case they would do that after 9.0Am and once that is done they want the state of the database back to 9.0Am

What i am planning to do is:create a restore point at 9.0Am and once application testing is done recover until restore point. ..But i was suggested not to do that way instead my Lead want me to use just recover until timestampI asked what is the difference in doing in my way,the answer i got is by using recover until restore point, the recover process cannot apply incremental level 1 backups and it just restores to a point of incremental level 0, it looked strange to me.
