I've never done this before and no one on my team seems to have idea if possible. In our environment, backups are performed using netbackup to bands using RMAN. I have a request to recover a good full backup of an oracle database (where we can restore the database, if required in the future) of January 13 and place in a way they provided for example: / dbbkup/dbName/files.
The backup team tied the tapes required for this backup, which in this case is January 13, 2016, see below. We can only use RMAN to restore this backup, but I don't want to restore this backup on a database, instead would like to capture the full backup and zip and place it in the provided path. Is there is a possibility with RMAN?
If yes I would appreciate the full commands necessary to capture all of the basic + archivelogs (how can I determine what archivelogs are needed?)
I came with thisbut do not know if this will do.

Yes, we cannot copy the backupsets of a band on the disc with RMAN.
The only option is to restore the database to a separate host computer (or we can restore the database to a filesystem separte or diskgroup within the same host of source database), and backup the database on a disk in compressed format.
Hi guys. How can I remove database with file init lost? I just want to recreate the database (with recovery or restoration of the process)
1. I can't start because I do not have init. 2. I can't delete the database because I can't start. 3. I can't recreate database using dbca as the same name somewhere is:)
Published by: America on January 18, 2009 12:03
When you run "dbca" you can select "delete the database" and find the old name of the database? If find... You can select and delete... dbca will ask... But you and click on remove in any case.
We check if our backups are valid or not. So it gave me a new server and backups/archives to a 2 TB database I need to restore/recovery. I followed steps below.
(1) copied the prod parameter file to test.
(2) make the necessary changes in the init file.
db_file_name_convert, etc..
(3) start db in nomount mode.
(4) restore the backup control file
Restore controlfile to ' / oraback/ARCH/prod/backup_controlfiles/c-250795000-20141030-01';
(5) mount the database.
(6) created under the rman script and executed.
Run {}
Catalogue start with ' / oraback/RMAN/test "noprompt.
Catalogue start with ' / oraback/ARCH/test "noprompt.

Questions-
-Restore completed successfully, but I found that few archives are missing.
-I pulled from database to recover until cancel using backup controlfile; There is a below error
ORA-01152: 1 no file has been restored from a sufficiently old backup
ORA-01110: data file 1: ' / u02/oradata/testsystem01.dbf'
-Then tried to restore the archive of available backup archive and few of archives have been restored.
i.e. of sequence between 759529 and 759552.
And then I pulled the database until cancel using backup controlfile recovery and I got errors below.

After you create the database, it is automatically saved with the listener. I am not registered the database with listener then how it registers itself automatically with the listener. How a registry database that is automatically saved.

Can someone tell me please how to enter Oracle Database Vault with a database from command line without using DBCA.
The doc oracle E23090-10 provides only through the DBCA Wizard. I'm having some trouble with my software x - manager, so I cannot use the DBCA Wizard and seeks to enter the vault of the database with the database by command line.
Oracle database Vault is already enabled through 'chopt enable lbac' and 'chopt enable dv. Now all I do is register with the databases on the server.
Thank you
Hi DK2010, actually I found my answer in the metalink Doc ID 803948.1

I need to create a database with the character US8PC437 (platform Linux Redhat 5.4 64-bit, database version 11.2.0.3), but this character set do not appear when I create the database with the database assistant (DBCA).
Any help will be apreciated.

While AL32UTF8 is certainly recommended for the Oracle database character set, use only, if your application provider has confirmed that their application will work with a set of characters to multibyte database.
To create a database US8PC437 (it is rarely a choice, in fact) with DBCA 11.2, select the "character sets" tab, once shown, then select the option 'Choose from the list of character sets' and uncheck 'Show recommended only character sets '. This will add US8PC437 to the "Database character set" drop-down list. Select "US8PC437" from the list and continue the process of creation.
But first, contact your provider and ask a compatible Unicode version of your application.
Hello. I use the server of Oracle 11 GR 1 material with operating system Oracle Linux 5.10 database.
I understand how to back up the database instance in SQL Server with Windows. But do not really understand how to back up the database instance in Oracle on Linux. I did it cold and hot backup for the database HRCS90 instance, but both receive the same error message.
Cold backup is below:

While the instance of database HRCS90 is starting, I do hot backup by using the same commands and get the same error message with above cold backup.
My question is:
Can any folk tell me specific steps (order by order) to back up a single instance of the database in Oracle with RMAN?
Thank you.
Yes, you can restore and recover the backup, but not at the moment. You will only be able to restore and recover at the time of your backup.
For example.
If you take backup (mount point with no mode of journal archive) at 06:00 and your grave database crashes at 21:00, you will be able to restore and recover until 06:00. You will find all the changes made to the database between 06:00 and 21:00.
If you want your database to recover until 9 PM or until a point in time, then you must put your database in log mode archive, and then save the archives.
I am facing a problem with the Oracle database, which is linked to archivelogs. Our development database is running in archivelog mode, but we don't have safeguards and have no recovery catalog. When the database was in running, disk got full, so some archivelogs were deleted manually. After that they have restarted the DB, and DB now not come. The errors are as follows:

It is actually quite easy. We knew that Oracle was looking for logsequence 1107. There is no archived log, it was deleted, or it has never generated. As you delete files, the 1st solution would be possible, BUT as there was only an instance crash so more old archived logs is not required for crash recovery. There is a need during the restoration of the old backup files, which is not our case.
Thus, the missing log sequence has not been archived = > it is a redo log. To identify the required online redo log, we just to log query v$ as I suggest.
Once the log identified file, we can recover it by specifying the redo log when you ask logsequence 1107.
I have a problem with a database of oracle 11g XE on windows server 2003, the database is in production, it is open, is operating normally.
The database has no backup configured before, so I put the database archiving mode and tried to backup using rman utility, but it show me some errors.
First of all, it showed me:
ORA-19501: error in reading file... SYSAUX. DBF
ORA-27070: async read/write failed
OSD-04016: error queuing an asynchronous i/o request.
And when I passed the dbv on the SYSAUX file utility. DBF showed the fatal error.
So, I switched CHKDSK utility on windows to repair the disc of the error. After that, run utility dbv and he passed and showed me the corrupt on SYSAUX blocks. DBF
Then, came to rman and ran:
RMAN > validate the logical database checking;
State of the file marked corrupt blocks examined empty blocks high YVERT
Finally I try to rerun rman and he shows me the error:
ORA-19566: exceeded the limit of 0 blocks corrupt file C:\ORACLEXE\APP\ORACLE\ORADATA\XE\SYSAUX. DBF
How can I do backup with rman? Maybe I can by pass the corrupt block?
I'll be grateful for any help you can provide.
=)
It would be better if you try to find the reason of corruption and try to recover the corrupt blocks. A block corrupted in the backup would really not must use. But if you're ready to take backup, you can ask RMAN to ignore corrupt blocks and move forward.
Every time you pass a cold backup database. We create a new controlfile with new locations of data/redologs etc.
And then we execute "create controlfile reuse...". noresetlogs...; "to create the controlfile.
After that, we will open the database as > > alter database open;
Now the question is:
We are able to open the database without clause "resetlogs.
Here, we create a new controlfile so SNA to controlfile will not be synchronized with the SCN of the datafile and redo the file.
Please let me know how the new controlfiles' SNA is synchronized with the data file and redofile and wea are able to open the database without resetlogs clause.
Oracle: 11.2.0.4
OS: Linux
If your cold backup also includes online redo logs, a RESETLOGS is not necessary.
The controlfile is created if it does not have a SNA, it reads the data file headers the YVERT database. For a cold backup, all the headers of data file are consistent. (This is also the reason why a RECOVERY is not required).
I have this request which I am not able to solve. There is a location of the log archiving mentioned as /oraarch/app/oracle/oradata/snlprod/archive_logs/in the parameter log_archive_dest_1. But the archive logs appear in another location/orabackup/rman/snlprod/archive_logs. I wonder how the archive logs show at this location, / orabackup/rman/snlprod/archive_logs.
I assume that there is only one way in what place can be given which is seen availability-> restore settings-> Media Recovery.
Hopefully, my question is clear.
Please get back with the answer to my query.
Concerning
Check the location of the archive log backup in the script. What is /orabackup/rman/snlprod/archive_logs.
I'll try to be as clear as possible with my goals and limits of the system, I'm working with:
1. we have a test instance of our Oracle database I want to be able to update with data from the instance of production at any time, without having to close the production database or tablespaces in backup mode to warm.
2. the two systems are HP Itanium boxes with different numbers of processors and RAM. These differences have been taken into account in the file init.ora for instances of the DB.
3. test and production instances use a SAN to maintain the following file systems: ora_redo1, ora_redo2, ora_archlog, oradata10g. The test instance uses snapshots SAN (HP EVA SAN series) the production file systems into the data when necessary. The problem is that the single window to do it is when the production system is down for maintenance every night, which is about a 20 minute period. I want to escape this limitation.
I do use the aforementioned SAN HP to take snapshots of filesystems on the production system. I'm doing this, while the production DB is running. I then import these snapshots in the test system, run a fsck to the integrity of system files, and then start the Oracle instance as follows:
Startup mount
Then I run the following query, I found online to determine the current redo log: Select Member from v$ logfile lf, v$ log l where l.status = 'CURRENT' and lf.group #= l.group #;
Then I try to run a recovery as follows: recover database using backup controlfile until cancel;
When you are prompted, enter the path to the first of the current redo logs and press ENTER. After waiting, sometimes it is said that the recovery is completed, other times it stops saying there was an error and that several files are required to standardize the DB.
I took the road above because to do a recovery until the time (which is what I really want to do) kept invited me for the next archiving log in the sequence that did not exist when I took the picture of SAN. This is my back up to the order of time:
recover database until time ' yyyy-mm - dd:hh:mm:ss using backup controlfile;
What I want to do is to take the SAN snapshot and then retrieve the database about a minute before the snapshot by using the archive logs. I don't want to use RMAN, since it seems like overkill for this purpose. A simple recovery to a specific point in time seems to be all that is needed and I archive logs which, I suppose, SHOULD help me get there. Even if I lose the value of the last hour of trading, I could live with that. But my tests affect the recovery time even 12 hours sooner more resulted in a command prompt to the next, no archivelog.
I note also that I even tried to copy the next log archiving on once there is and the recovery would then invite me to the next archive log! I recognize now that I know really much about Oracle or DBs, but it's my duty to try and make it possible to "Refresh" the DB test with the latest data with no impact on production DB.
The reason why I want to use the hot backup mode, it is that I don't know the other DB schema that there probably 58 or more storage spaces. The goal is to use SAN snapshots for their speed instead of having to take RMAN files and copy them to the test instance. I don't know that I'm not the only person who has already tried that. But most of what I found online made reference on RMAN, hot backup mode, or downtime. The first two take advantage of SAN snapshots for a quick exchange of all Oracle file systems, and I can't afford downtime other than this window during the night. Is there a reason that did not retrieve it in time even if I archive logs?
One last point. Recover until cancel actually worked a few times, but it seems to be sporadic. Probably has something to do with what was going on on the production DB when I created the SAN snapshots. In fact, I thought I had a solution with recover until cancel last week until he failed three times in a row.
As I've mentioned before, I highly recommend setting the database in BACKUP mode.
You can see a collection of papers to the http://www.Oracle.com/technology/deploy/availability/htdocs/oscp_papers.html Unfortunately, Oracle stopped the Oracle storage compliance program and now he leaves vendors to certify their memory and their file system. The documents on the site of the OSCP are now "old."
Each storage provider has also published articles. I worked with snapshot / SnapClone / SnapView / technologies ShadowImage EMC CLARiiON, Hitachi Lightning, IBM ESS, etc. of NetApp. Only the EMC engineer did not recommend the BACKUP mode. However, when you test the EMC under high concurrency, we found corrupt index when we used the image of the snapshot. I returned to the EMC site and downloaded a specified document that we had to use the BACKUP mode and SUSPEND / SUMMARY - and why said. The main lines were "However, the operation of fracturing the clones or from sessions of snapshot with multiple devices is not atomic. Particular periods may exist as well and all of the Oracle files being backed up can seem to have lost the required I/O order sequencing. ». So it really depends on the technology. The engineer later confirmed that it was a requirement on the particular type of storage we were using, but not on the DMX class (or something like that - I don't remember all the details of a previous task a few years ago).
(White papers of all other providers also included BACKUP mode).
Contact the vendor for their own white papers.
