View 1 RepliesI am trying to backup a database and am having a couple problems:
1. When I log into RMAN for the database in question and run a simple backup database I get:
Quote: ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode message
2. I then logged into sqplus and shutdown / restart the database
3. when I try to restart it - it fails to starup claiming:
Quote: sqlplus Error: ORA-12560: TNSrotocol adapter error
4. I have tried to login in locally (not using Quote: @<dbasename> but I get the same error message as above. I have set ORACLE_SID and LOCAL to the database name and still the same TNS name error

We want to keep the Guaranteed restore point for week but unfortunately we don't have enough flash space in the server. Is it possible to backup the flashback log(restore point logs) through rman and send bkp file to tape? how to restore the database in new server until Guaranteed restore point.

View 6 Replies View RelatedWe are doing RMAN Duplicate set until time to refresh daily our test database for our developers and it taking long time to finish. We noticed on the restore log that RMAN was using a day old old backup pieces to refresh the test database and don't immediately use the latest backup pieces instead.
For additional details here's the rman duplicate command we are using which we run daily(mon-sat) at 4am once daily full backup on production completed.
RMAN Duplicate commands:
run
{
set until time "to_date(to_char(sysdate,'Mon DD YYYY') || ' 04:00:00', 'Mon DD YYYY HH24:MI:SS')";
allocate auxiliary channel ch1 type disk;
duplicate target database to testdb;
}
exit
Is there a way on how to let RMAN use the latest backup pieces instead?
Is it possible to restore dropped table OR wrongly updated table using RMAN backup.

Our external consultant configured RMAN scripts for full and incremental backups but never tested them . Since he just doesn't show up, I'm forced to tested them, restoring the whole database in a new server.
My instance is named MTDPROD, and I will create all from scratch.
At current server, RMAN files are generated in:
//192.168.1.149/g$/XXXSRV4-ArcLogs/MTDPROD/RMAN
At new server, I run all these commands:
C:>oradim -new -sid MTDPROD -intpwd mtdprod
Instance created
-- I created the relevant folder hierarchy under <ORACLE_BASE>
directory
-- Then, I created the relevant directories for Oracle Database, as
follows:
--a. Create BDUMP, CDUMP, and UDUMP directories under '<ORACLE_ BASE>
[code]....
By instance, I see a lot of this kind of files:
- FULL_MTDPROD_20110529_386_1.BAK
- INCR_MTDPROD_20110621_480_7.BAK
And only see these two files:
- C-2169285856-20110527-03
- C-2169285856-20110527-04
It seems that this C-2169285856-.... files only were on 27/05/2011 and then no more. However, the FULL_... and INCR_.. files are generated every day. The FULL is generated at the end of each month and INCR is generated every day.
This is the backfull.sql:
run {
allocate channel c1 type disk maxpiecesize=4G;
CROSSCHECK archivelog all;
backup
incremental level 0
format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANFULL_

We have the requirement of performance testing of our proposed production platform, for this i am asked to take RMAN backup of clean position (Say Day0 or baseline backup) and restore it multiple times for few rounds of testing. My question is after 1st restore (with set until time of day0 position) if i open the database with resetlogs, would i be able to restore same clean backup again? I am using control file in the environment instead of RMAN catalog database. What i can do to make this scenario work? I am already in preperation of setting rman catalog database.
View 3 Replies View RelatedI am attempting to use an rman backup form our live server to restore live data over an existing dev database with a different name. I cant use the duplicate command as the versions of oracle are different (10.2.0.4 EE on live, 10.2.0.5 SE on dev) So I copied the backup sets including an autobackup control file onto the dev server. I set the ORACLE_SID to the DEV version (SUN43DEV) and startup nomount and restore controlfile from the backup location. This works and restored the live controlfile. However, I then wanted to mount the database and catalog the backupsets before making a note of the last archivelog etc and restoring the backup with set newname options. But when I try to mount the database I am told that the database has a different name (SUN43 is not SUN43DEV). I read somewhere that I need to set the ORACLE_SID to the live value (SUN43) and restore as that, then use nid TO RESET THE DBID and DATABASE NAME. However, my tnsnames on DEV has no entry for the live database, and we do not have any service defined through ORADIM for the live instance on the dev server. Should I be creating an entry in DEV tnsnames that actually looks at the LIVE server? or do I need to create a service and tns entry etc for SUN43 on my DEV server pointing at the DEV server I have not seen any mention in instructions of creating a service or adding the entry to tnsnames, or indeed adding an entry to the listener for the original live sid. I am worried that if I actually point to the live server then the restore would be attempted on the live server not dev even though I am running it from Dev.
Also, do I need to drop the existing database on DEV before I restore or will RMAN just restore over the top of it?
Finally, if I try to add an entry to the LISTENER.ORA for the new sid, when I stop and start the listener, or reload, the entry is not recognised. I also noticed that the existing SUN43DEV entry is not in there either, yet I can still use that SID - I am assuming that is because the listener is not being used and the sid is recognised from the existence of the service in windows services instead?
I am having a issue, we are trying to restore our db from control files using Symantec Backup exec, but job fails giving me error go to table spaces select all table spaces and unchecked roll forward.
i am unable to find way to uncheck the table spaces. Here is the complete description.
Cause
The system catalog tablespace "syscatspace" contains all of the system catalog information for the tables. Syscatspace needs to be rolled forward first, and then the other tablespaces must be rolled forward.
Solution
Workaround:
When the restore operation is run from a tablespace level backup, perform the rollforward for the syscatspace tablespace first and then for other tablespaces.
Execute the rollforward operation as a DBA operation. The sequence of the recovery process should be as follows:
1. Select all tablespaces, uncheck the rollforward option and run the restore job.
2. Run the rollforward operation as a DBA initiated operation:
rollforward syscatspace to point in time / end of logs. e.g. db2 => rollforward database UEXIT to end of logs and complete Tablespace (SYSCATSPACE) online
3. Perform rollforward of all other tablespaces.
e.g. db2 => rollforward database UEXIT to end of logs and complete tablespace (SYSTOO LSPACE,USERSPACE1) online
Refer to IBM DB2 documentation for more information on DBA-initiated operations.
can we restore database from obsolete backup using rman
View 2 Replies View RelatedI am trying to create my database on a new server using rman incremental hot backups.
I have already restored and recovered my level 0 database on new server, but i am not able to restore/recover the level 1 backup on the new server. I have transported level 1 backup irom the old server to the new one. Do i need to recover lvl 1 bkp only or restore it also.
I need to restore entire database(sp+control+datafile) to new host.I have started the instance with nomount( and it has created a dummy parameter file).Now, I need to fire the command to restore spfile.
RUN
{
ALLOCATE CHANNEL c1 DEVICE TYPE sbt PARMS='...';
RESTORE SPFILE TO PFILE '?/oradata/test/inittrgta.ora' FROM AUTOBACKUP;
SHUTDOWN ABORT;
}
My questions:-
1.How will RMAN find the location of backupset(Since there is controlfile for neither target or catalog database)?
2.How does RMAN reache the backupset in case of a)tape b)disk?
I have been updating data in my database by adding numerous rows and assume the insertion of rows started from 1st date of january month.
I have been entering somehow or the other part of data every day.And now the date is 25th of january.
How can i take a partial backup of my database of the transactions done between 15th of January to 20th of January Month
How to take Backup of a particular date say it be 12th of january month.
How to take backup of first 10 days i.e., 1st-10th of january.
n my last post I asked abt the issues that I was facing while restoring the full backup of RMAN on a new server. I mentioned the steps as well, Now my Question is what If I want to restore the incremental backup on the new server?
What all steps do I have to follow after restoring the zero level backup on a new server.
my restore scenario bellow.
I have hot full backup that processed by NetBackup Policy. the backup policy are;
1.Full backup database in Monday. Daily_Monday_RMAN <- 1 volume pool=1 media
2.Full backup database in Tuesday .Daily_Tuesday_RMAN <- 1 volume pool=1 media
3.Full backup database in Wednesday. Daily_Wednesday_RMAN <- 1 volume pool=1 media
4.Full backup database in Thursday. Daily_Thursday_RMAN <- 1 volume pool=1 media
5.Full backup database in Friday. Daily_Friday_RMAN <- 1 volume pool=1 media
6.Full backup database in Saturday. Daily_Saturday_RMAN <- 1 volume pool=1 media
How to restore database from one of medias?
I take hot backup of database at 10:00 am.After taking the hot backup 50 archived logs are created.Out of 50 i have backed up first 25 of them and at 5:00pm i lose complete database including control,data and the last 25 archived log files that were not backed up.So I am using latest hot backup to recover
I restore the control file backup and datafile backup taken during ho tbackup(10 am) and i issue the command
.......startup mount
>>>>>>>Recover database until cancel
!!!!!!! Apply the available 25 archive logs
then i give "cancel" since I dont have the next redo log .Now in which mode will the database open(Reset logs or no reset logs)
I ran the Full database backup as,
RUN {ALLOCATE CHANNEL CH0 TYPE 'sbt_tape';
BACKUP DATABASE FORCE PLUS ARCHIVELOG FORCE NOT BACKED UP DELETE INPUT;
RELEASE CHANNEL CH0;
}
Then I ran the restore, it failed with Quote:RMAN-06054: media recovery requesting unknown archived log....
When I backup archivelogs and choose to delete the input, it does not delete the multiplexed copy, but the specific file being backed up.So, ideally it should find it in Flah Area or at least in the backed up pieces which are there with it.Still why is it failing?
Also, in recovery, it is deleting the archived log after applying, RMAN does this if we use recover... delete archivelog command.I am using only RECOVER, still in output I can see RMAN deleting the log after it has applied it. WHY?
I want to restore control file from backup set,just as the flowing command,where location does the control file be restored to? how can i specify the location when restore control file?
restore controlfile from '/u01/rman_backup/mybak/df_768589733_7_1.bak';
i want to clone the test db to dev db but i dont want default users and tablespaces(SYS,SYSAUX,...) in the test db datapump and exp are not working, then contacted ORACLE support and they concluded that test db sysaux was corrupted.i took RMAN all tablespace bkup except default tablespaces. then created new database using DBCA and now i want to restore and recover all those test db tablesapces but while i'm doing restore its saying
RMAN> restore tablespace MAIN_DATA;
Starting restore at 07-SEP-12
using target database control file instead of recovery catalog

i created all tablespaces in dev same as test db,
I would like get a copy of an oracle 10g database off the production server(windows 2003) and set it up on Windows 2003 virtual server to use for dev/testing.
What would be the safest and most efficient way.??
We need to migrate database from old machine to new machine. This is because our SAN storage need to be change due to file system.
Old machine setup with RAC and using 10g. Is it possible i restore at single machine only? The backup on the NAS. SAN act as ASM only.
I need to restore a backup of database A from into Database B. Both have the same names. Database B is already up and running.
I have a full rman backup of Database A ( it was taken with a recovery catalog which I don't have access to now as it was deleted ). I just have the full backup pieces including the control files. Is it possible to recover this database into Database B from this stand point.
I was thinking
2. Shutdown database B
3. Mount database B. It has same name as Database A.
4. With RMAN restore controlfile. Will a new controlfile be created from the backup directory I have the rman pieces for the full backup in ?
I have Oracle loaded on a server. I have three database instances - /db1, /db2, /db3. I want to put the database in backup mode before I take a backup copy of the three database instances.
Is the database put in backup mode just once and then the three instances can be backed up? Or does each instance need its own script to put the database in backup mode?
changing archive mode during DB running.Before in 9.2, 'ALTER SYSTEM ARCHIVE LOG START/STOP' is available for this job. But, after 10g/11g, it cause 'archive log stop has been deprecated'.
However, for my practice, I need to estimate archived logs size before backup them, so I need to stop archive log for a while and enable it later during DB running.
I check Oracle documents, it only mentions changing archive log mode at DB mounted but not open.
I wanted to backup my entire database using tar and then recover it from the compressed tar, what directories I should backup using tar? As well as how would I restore it?
View 2 Replies View Relatedon our 10.2.0.5 database, when we run full backup, my system performance comes to an halt. we run full backup and then do a validate backup to validate the structure of the database etc. Database performance takes a hit and all of the application connections goes in wait mode: On ASH or AWR - this is the top wait i see:

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