I have a 10G Express system running. I Have 2 tablespaces in production. WHen taking backup, it terminates unsuccessfully saying system01.dbf is damaged. The application works fine and no data loss is found through the application interface.
So can I shift the data to a new server using the dbf files of the tablespaces in use?
I have an oracle autoback of controlfile and spfile. I am trying to restore the production database using this backup, into a new server with a different directory structure.
I have completed the following steps in the restore process.
1. Creating a pfile from spfile
2. Changing the the location of cdump, udump, bdump and the control files ( there are three )
3. Then creating a spfile from this pfile
I am stuck on the next step where to rename all the datafiles and tempfile and restore the database. Following is what I did.
After mounting the database in RMAN, tried to run the following.
RMAN> run
2> {
3> allocate channel c1 device type disk
4> ;
5> @/home/oracle/rman_scripts/newloc.rman
6> SET NEWNAME FOR DATAFILE 1 TO '/u02/oradata/dorian/system01.dbf';

9> SET NEWNAME FOR DATAFILE 4 TO '/u02/oradata/dorian/users01.dbf';

I am getting the following error message.

db can only be opened if all the datafile and controlfiles are synchronize.I wonder if db crash and we dont have any kind of backup. is there some way to synchronize the control file with the datafile?....any way.db is not idle either when crashes we can manage data lose.just want our database open

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.
Is the tablespace actually off-line when doing a user-managed hot backup? I know the data blocks are copied into a redo stream but I am not sure if that means it(tablespace) is actually on-line or off-line.

The problem is at times there may not be any archive files that meet this criteria and RMAN throws an error

While testing on several systems, I found that the above-mentioned query picked up some redo-logs (*.rdo) I can only assume that these redo logs were used for a DB recovery.

So i need to restore archivelogs by using sequence
RMAN>RESTORE ARCHIVELOG FROM SEQUENCE 20 UNTIL SEQUENCE 28;
So the restore is completed successfully
So its very hard to monitor archivelog files
i feel i should have included all archivelog files while taking RMAN backup
RMAN >backup database plus archivelog all delete input;
but the problem is my RMAN backup is already 360GB in size and it takes 4-5 hrs to complete .so i need to schedule RMAN backup at one time (e.g sunday) ,delete the archivelog files older than sundayand now schedule the archivelog backup at another day (e.g wed &sat)
my question is where i have to change my script to backup all avaialbe archivelog files if old archivelog files are deleted at os level?

Now,i want to implement hot backup on my oracle database which install the linux operation system ,but i expect the hot backup files can storage on the servers of the Windows operation system directly.
I have one question to clarify regarding backup.
There is an incident that in production database 1000 archive log files generated.From 1000 files, 100 archive log files have been removed.When i take incremental backup next day , what will happen in database?
I have been experimenting with RMAN over the past few days and have a fairly strong grasp on it. I setup a test scenario using a three tier incremental approach as follows:
Every four weeks take level 0
Every 7 days take level 1
Every day take level 2
Obviously I'm only taking one per day, so on days I take a level 0, I'm not taking a level 1 or 2. My scripts look similar to the following, with change to incremental level number.
rman target / <<EOF
run {
configure device type disk parallelism 4 backup type to compressed backupset;
configure default device type to disk;
configure backup optimization off;
configure controlfile autobackup on;
configure retention policy to recovery window of 4 days;
[code]......
What I'm trying to understand is what files Oracle is creating in the flash recovery area. I have several sets of files:
In the root level of the FRA, I see several files per incremental backup with names such as aambg4sa_1_1, aqmbg5mj_1_1, b6mbg614_1_1, etc. I was under the impression that these were the incremental backup pieces, multiple files because I'm using parallelism of 4.
Under a /FRA/<SID> I see 3 directories: archivelog, autobackup, and backupset. I assume arhivelog is where Oracle is archiving the redo logs, autobackup is storing the SPFILE and CONTROLFILE as I have enabled controlfile autobackup. However, what is being stored in backupset?
When I do a crosscheck, it lists the files within backupset, but does not list the several files under the root of FRA (b6mbg614_1_1 and so on).
What's the difference between /FRA/<SID>/backupset and the files under root FRA? Do I need both for recovery - and if not, why is Oracle keeping both?
I have the following situation: a customer sent me a group of files, that he said to be a "backup" of an old database, that is no longer online (he doesn´t use our software anymore). However, he needs to recover the data in this database. The person at the company who generate these files doesn´t work there anymore, so we don´t have any of the following information:
- Database version, connection details, service names, user names neither tablespace names.
We were just told that these files were recorded in a DVD, and is que only source remaining.
The files he sent are the following:
ctrlcf_satp_01.ctl
ctrlcf_satp_02.ctl
ctrlcf_satp_03.ctl
daddf_satp_dad_01.dbf
[code]......
Is there a way to access this data? Or can I tell our costumer that your data is lost forever..
I had a database on an old P4 running but the motherboard got fried. I was able to recover all the data files (.ctl and *.dbf) plus the redo logs (.log). There is no export or backup taken - I have old ones, but I need to recover the latest which only existed in the data files.
I now have Oracle installed on a new P5 machine and was wondering if it is possible to use these data files in the new database? If so, how do I go by restoring the data files?
Both the P4 and P5 where running Red Hat Linux.
In the backup and recovery session i have miss my online redolog files. why the datafiles are recovered.it's possible to recovered to online redo logs?

I have oracle installed in c drive. I have placed 3 datafile related to one tablespace say test: two in D and one in E. I have place 3 datafile related to tablespace say orcl : two in D and one in E.
my undo is in E scenario is that my E drive crashed . db is in no archive mode . no backup is there. to be more worst db shuts down abnormally. I want my db open with data of c drive and D drive.
Is it possible to recover files from backup tapes which are gone obsolete (as per retention policy)?
View 4 Replies View RelatedI took backup of Datafiles , archivelog files and controlfile through RMAN. Now, i want 3 backup file will created as a output of RMAN operation. It would be :
1 backupfile for all the datafiles
1 backupfile for all the archivelog files
1 backupfile for controlfile.
It have to be regardlessly whatevr my DB size is. It it possible to do so. How i can can write rman script to accomplish the task.
We have a nightly rman backup that was complete and clean.The backup contains a Data File, Control File and a backup Archive Log file.The database server crashed with all the subsequent archive logs lost.
We are trying to recover from the three backup files.We are bumping into the backup piece missing as all the archive logs are done. how to restore with the exising backup files. the lost archive logs are probably salvageable.
I've got a legacy SAP system with oracle 8i on Tru64. No changes at all are made but for legal reasons we have to keep it up and running.
we currently do a full backup monthly by shutting down oracle and doing a backup of all the files to tape and that takes around 12 hours.
If I stop doing the full backup and I only backup the control file and the archived redo log files every month and I had to restore the full database years from now, would I be able to restore the database using the last full monthly backup and use the latest control file and archived redo log files?
I'm rying to import schema's from a dump file that came from a different environment.
What I have is:
1. dump file
2. log file of the export
I'm trying to import the file(containing three schemas) with remap_schemas, and it fails, gives a lot of ORA-00959: tablespace 'string' does not exist.
Now, I've read in OTN:
[URL]
that what you need to do in that case is to use the REMAP_TABLESPACE option,to redirect the objects to a different tablespace.
I don't see a name of the tablespace I'm getting the error for in the export log.I don't know if I have more tablespaces I have to redirect with REMAP_TABLESPACE.
I don't want to perform this 3 times, have an error, by that find out what's the next tablespace needing redirection and only then starting over...
How can I know from the dump file and the log file,what is the tablespace names i need for the redirection to my names? Or its just that the tablespace giving me the error is the only one in the dump file?
Backgroud info:
host server crashed.
Database was not cleanly shutdown.
Database is not in archivelog mode.

Install new database.
ALTER DATABASE BACKUP CONTROLFILE TO TRACE.
shutdown database.
Place available dbf files in the location for new database, replacing existing files.
edit trace file to create new controlfile. Script is:

I've read a lot about the different types of backup available with Oracle (hot and cold backup). However, I was thinking of a different way of performing this task. I'm currently using Windows Server 2008 R2 and Oracle 11g Standard Edition. I'd like to schedule an entire backup of my server via the utility "Windows Server Backup" (available for free).That way, I could recover my entire server with all the programs and files in case the latter crashes.I'm wondering if this solution could be used as a way of backing up (and recovering) the Oracle database. Should I still set up a regular hot backup with the Archivelog mode enabled in case some operations/transactions were being done at the time of the crash (for the data integrity)?

I 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 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.
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.
FIRST Question?
I have main database Server which is located on Server A, now I have to take the RMAN Backup of Server A and then shift the complete database on new Server B.
I am confused whether to use Backup command with AS COPY option or take the backup as backup sets. Which are the best option that I can use for the RMAN Backup.
We are using HP data Protector as oracle database backup tools.but we are facing below error. But we are able to login to the database through same user.
