Datafiles in FRA... :)
Hi All,
I would like to share my doubts about ASM and FRA(Is this section the right one to put this doubt?)...
*I know about the retention policy in FRA and that files will be deleted automatically and that production datafiles should NEVER be moved to the FRA area.
But,
Using ASM I have two diskgroups, for data and FRA. FRA area is oversized (5G normally used of 300G total,backups are not placed here...) can this area(FRA) be used temporarily to guard some datafiles(data diskgroup running low...)?Which is the risk?Or Is it better to just put the datafiles outside the diskgroups?
Can you share histories (crash?,data deletion?duh..)
Using a test environment(no-ASM,no-RAC) I put a datafile in the FRA area but the view V$FLASH_RECOVERY_AREA_USAGE did not update...Is it normal?No?How refresh it?I already use crosscheck's rman..
Which is the best way to resize the FRA diskgroup and remanage the space to the data diskgroup?(external redundacy, FRA diskgroup is listed to have 1T by Enterprise Manager, db_recovery_file_dest_size=300G...)
Oracle DB version 11.2.0.3.0(RAC)
Linux version: 2.6.32.el6
Using Oracle ASM
Using ASM I have two diskgroups, for data and FRA. FRA area is oversized (5G normally used of 300G total,backups are not placed here...) can this area(FRA) be used temporarily to guard some datafiles(data diskgroup running low...)?Which is the risk?Or Is it better to just put the datafiles outside the diskgroups?

Regular datafiles are not taken into account in V$RECOVERY_AREA_USAGE. Even if you use rman "catalog recovery area", rman will skip them. Therefore database will not remove them.
Which is the best way to resize the FRA diskgroup and remanage the space to the data diskgroup?(external redundacy, FRA diskgroup is listed to have 1T by Enterprise Manager, db_recovery_file_dest_size=300G...)
You can move disks between diskgroups. Or you can temporary disable db_recovery_file_dest (putting logs and other files to new destination), remove diskgroup, resize LUN and create new diskgroup.

ASM Disk preparation for Datafiles and FRA in Oracle 10g RAC Inst
Dear Friends,
Please clarify wheteher the below method is correct to confiure ASM disks for Datafiles and FRA
Partitions provided by IT team for OCR and Voting Disk
/dev/sda1 - 150 GB (For +DATA)
/dev/sda2 - 100 GB (For +FRA)
OS : RHEL 5.6 (64 Bit)
kernel version = 2.6.18-238.el5
Steps:(Node1)
1) Install the RPM's for ASM
rpm -Uvh oracleasm-support-2.1.7-1.el5.x86_64.rpm
rpm -Uvh oracleasm-2.6.18-238.el5-2.0.5-1.el5.x86_64.rpm
rpm -Uvh oracleasmlib-2.0.4-1.el5.x86_64.rpm
2) Configure ASM
/etc/init.d/oracleasm configure
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]:
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLib disks: [ OK ]
3) Cretae ASM Disk
/etc/init.d/oracleasm createdisk DISK1 /dev/sda1
/etc/init.d/oracleasm createdisk DISK2 /dev/sda2
4)/etc/init.d/oracleasm status
5)/etc/init.d/oracleasm scandisks
6)/etc/init.d/oracleasm listdisks
7) Nothing to perform on Node2
8) In dbca choose ASM and map the DISK1 for datafiles and DISK2 for FRA
Please confirm the above steps are right?if not please clarify

After renaming data file it failes during database open
Hi,
I took RMAN full back.
Then i renamed datafile then restored and recovered. It goes fine.
But during the daabase open it fails with
ORA-01113: file 6 needs media recovery
ORA-01110: data file 6: '+OBTDG1/qa112asm/datafile/users02.dbf'
Any specific reason for that?

Shared file system recomended for OCR and voting Disk in 10g R2
Dear Friends,
For Oracle 10g R2 (10.2.0.5) 64 bit which shared file system is recomended for OCR and voting Disk (NFS / raw devices / OCFS2)
For Datafiles and FRA i planned to use ASM
Regards,
DBHi,
If your using standard edition then you got no choice but raw devices
http://docs.oracle.com/cd/B19306_01/license.102/b14199/options.htm#CJAHAGJE
for ocfs2 you need to take extra care

I'm not sure exactly what caused this, but anyways, I changed MTU from 1500 to 900 online. After some time, 3 out of 4 nodes in the cluster went down and CRS refuses to start on these nodes after trying the switch back from MTU 9000 to 1500, reboots, and making sure disk permissions and ownership are correct. The logs are not too helpful (and cryptic) so I'm at a loss and appreciate any ideas or help.
The installation was successful, the RAC was up for a few days while running some tests (including restart of a node). Currently only a single node has everything up and functional, the others are not working. Below are some output that might help:
[root@ucstst11 bin]# ./crsctl check cluster -n ucstst11

Please help!For the most part this issue has been resolved. The SA partially changed to jumbo frames (OS, but not the switch), we reverted all the jumbo frame changes and the system is back online, except for one node (the one which was working ironically) not being reported via "crsctl check cluster -all", and one instance not starting due to it not seeing an interconnect (weird).
We did attempt to fully implement jumbo frames but that did not work hence the reversion. -
FRA´s datafile directory and tape backups
Hi again,
I have tried to find relevant information for my question, but instead of finding answers (again) which may or may not be helpful I hope someone can explain me.
We are running 10Gr2 databases with FRA´s enabled, currently backupping all using Oracle´s suggested backup to Disk devices.
Since we have copies of the datafiles in the FRA which takes up quite some (productional) storage space we are asked to stop the Disk backups, and backup things up to the tape device, which underwater is a TSM library.
How would this affect the occupance of the FRA? Will the datafile directory in the FRA be moved to the "tape" device if we implement (solely) tape backups; or is it only the backupsets and autobackups which would then be moved to tape?
I have tried several setups for which I wanted to set the datafile, backupset and autobackup directory out of the FRA, but I have not found a (working) way yet to set the datafile directory apart from it.
Advice or help are greatly appreciated.
RobinChanging the backup location from FRA to an external device will only effect backups (backupsets or image copies of datafiles,controlfiles,spfile,archivelogs). Possible (but not mandatory) components of FRA are archivelogs,backup pieces,controlfiles,online logs,image copies and flashback logs.
For performance reasons it's better to continue using the FRA as first backup device. Extend your backup strategy by backing the FRA itself to tape in regular intervals.
'BACKUP RECOVERY AREA' backs up recovery files created in the current and all previous flash recovery area destinations. Recovery files are full and incremental backup sets, control file autobackups, archived logs, and datafile copies. Flashback logs, the current control file, and online redo logs are not backed up.
The backup must go to a tape device, so RMAN issues an error if no sbt channels are allocated or configured.
Or use
'BACKUP RECOVERY FILES'. It backs up all recovery files on disk, whether they are stored in the flash recovery area or another locations on disk. Recovery files include full and incremental backup sets, control file autobackups, archived logs, and datafile copies.

released channel: channel1 -
I have got a 2 node RAC cluster.
I am running RMAN backup connecting to one of the nodes and then running RMAN backups to FRA.
Since I cannot backup ASM to tapes just like a normal file system, I have configured the MML to backup the FRA to tapes using "backup recovery area" command.
The FRA backup to tapes is successful.
Now if ever I need to restore / recover the database, how do I restore my backups from tape.
ie: I dont see a command to say -> restore recovery area , which will restore the backups to FRA.Or is there a way ?
If it cannot restore , then what is the point of backing up the FRA to tapes using the above command.
Any thoughts ?
AUJust try to restore database/tablespace/datafile using usual RMAN commands: RMAN will check if FRA is used and check if related backup is on disk or on tape. If backup is on tape, RMAN will read it using Media Manager Layer (MML) in a transparent way.

ORA-19612: datafile 0 not restored due to missing data
Hello,
I'm testing a restore of the controlfile. The database is in archivelog mode and autobackup is set to ON. I successfully did a full backup and backup as copy database.
To test I did the following:
- note the DBID
- shutdown the database
- renamed both controlfiles:
$ mv /u02/rcat/control01.ctl /u02/rcat/control01.ctl_old
$ mv /u02/fra/rcat/control02.ctl /u02/fra/rcat/control02.ctl_old
When I try to restore the controlfile form autobackup I receive the following error. What could be reason please?

Best practice: managing FRA
I was not sure this was the most appropriate forum for this question; if not, please feel free to make an alternative suggestion.
For those of us who run multiple databases on a box with shared disk for FRA, I am finding the extra layer of ASM and db_recovery_file_dest_size to be a minor inconvenience. The Best Practice white papers I have found so far say that you should use db_recovery_file_dest_size, but they do not specify how you should set it. Currently, we have been setting db_recovery_file_dest_size rather small, as the databases so far are small and even at 3x the database size, the parameter is still significantly smaller than the total disk available in that diskgroup.
So, my question; is there any downside to setting db_recovery_file_dest_size equal to the total size of the FRA diskgroup for all databases? Obviously, this means that the amount of free space in the diskgroup may be consumed even if db_recovery_file_dest_size is not yet full (as reflected in the instance V$RECOVERY_FILE_DEST). But is that really a big deal at all? Can we not simply monitor the FRA diskgroup, which we have to do anyway? This eliminates the need to worry about an additional level of disk management. I like to keep things simple.
The question is relevant to folks using other forms of volume management (yes, I know, ASM is "not a volume manager"), but seems germane to the ASM forum because most articles and DBAs that I have talked to are using ASM for FRA.
Most importantly, what ramifications does "over-sizing" db_recovery_file_dest_size have? Aside from the scenario above.
TIAAs a general rule, the larger the flash recovery area(db_recovery_file_dest_size ), the more useful it becomes. Ideally, the flash recovery area should be large enough to hold a copy of all of your datafiles and control files, the online redo logs, and the archived redo log files needed to recover your database using the datafile backups kept under your retention policy.
Setting the size of DB_FILE_RECOVERY_DEST_SIZE must be based on following factors.
1) your falshback retention target,
2) what all files you are storing in flashback and
3) if that inclueds backup then the retention policy for them or how often you move them to tape
The bigger the flash recovery area, the more useful it becomes. Setting it much larger or equal to you FRA disk group does not cause any [b]overhead that is not known to Oracle.
But there are reasons why Oracle lets you define a disk limit, which is the amount of space that Oracle can use in the flash recovery area out of your FRA disk group.
1) A disk limit lets you use the remaining disk space for other purposes and not to dedicate a complete disk for the flash recovery area.
2)Oracle does not delete eligible files from the Flash Recovery Area until the
space must be reclaimed for some other purpose. So even though your database size is 5GB your restention target is very small but if your recovery_dest_size is much larger it will just keep filling.
3)Say in my case I have one FRA disk group of 150GB shared by 3 different databases. Based on the nature and criticaly of the database I have different size requirement of flashback recovery area for these databases. So I use varrying db_file_recovery dest_size (30GB, 50GB,70GB) respectively for meeting my retention target or the kind of files and backup I want to store them in FRA for these databases.
Oracle Internal Space management mehcanism for Falshback recovery area itself is designed in such way that if you define your db_recovery_file_dest_size and DB_FLASHBACK_RETENTION_TARGET at a optimal value, you wont need any further administration or management. If a Flash Recovery Area is configured, then the database uses an internal algorithm to delete files from the Flash Recovery Area that are no longer needed because they are redundant, orphaned, and so forth. The backups with status OBSOLETE form a subset of the files deemed eligible for deletion by the disk quota rules. When space is required in the Flash Recovery Area, then the following files are deleted:
a) Any backups which have become obsolete as per the retention policy.
b) Any files in the Flash Recovery Area which has been already backed up
to a tertiary device such as tape.
c) Flashback logs may be deleted from the Flash Recovery Area to make space available for other required files.
NOTE: If your FRA is 100GB and 3 databases have thier DB_RECOVERY_FILE_DEST set FRA then logically the total of db_recovery_file_dest_size for these 3 databases should not exceed 100GB. Even though practically it allows you to cross this limit.
Hope this helps. -
RAC instance, trying to recover UNDO datafile, RMAN gives RMAN-06054
Hello all,
This has been a troublesome instance..a quick bit of background. This was created awhile back by someone else, I inherited this 3 mode RAC clusterof instance1.
I'm exporting out of one database (10G) into this instance1 (11G). When I was about to start the import..I found this instance wouldn't start. Turned out no backup had been going on of this empty instance. I backed up the archive logs to tape to free up the FRA..and things fired up.
I began the import, and found a bunch of errors...basically tellling me that I couldn't access one of the undo tablespaces...datafile problems.
I went to look and saw:

This is all on ASM, and am a bit of a newb with that. I bascially have no data I'm worried about losing, I just need to get everything 'on the air' so I can import successfully, and let users on this instance. I've set up the backups in GRID now....so, it will be backed up on the future, but what is the quickest, most efficient way to get this UNDO tablespace datafile recovered?
Thank you,

Hemant K ChitaleOops...meant to have start and set until both to "1"
However, I see what you mean. It seems I cannot find the file on tape.
Since the RAC instance hasn't yet had any data put into it, I'm thinking it might be best to just blow it away, and recreate everything.
Trouble is, I'm a bit new at RAC and ASM. I was thinking the best route might be to use DBCA to remove the database...? Would this not take care of removing all the datafiles from all the ASM instances on the RAC..as well as all the other directories, etc on all 3x nodes?
I've already used the dbca to create templates of this instance, so recreation shouldn't be too difficult (although it will be my first RAC creation)...
Thank you in advance for the advice so far,

Duplicating a database using FRA
Hello,
I'm trying to duplicate a database using a backupset stored in FRA.
However, I thought rman would go take the most recently backupset that I'd backed up but isn't what's happening.

How can I do to rman read backupset stored in FRA ?

Marcelo SinniIt's trying read backup piece from tape and this is what I don't want to.That's because you allocate manually a tape channel inside the RUN block:
allocate auxiliary channel c1 type sbt;For Duplicate use the same settings you used for the backup to the FRA.

Hi oracle's guru!
I need some advices and directions to learn.
I'm going to use FRA.
1. can i specific file formats for database backup files and control files? I run backup database plus archivelogs and there are 5 files with random names (rman generates itself). Can i add any tag for them?
2. Why i have 4 files instead 2? my database is not big enough. XE with default schemas.
regards,
rustamHi Jörg,
that depends on several settings. Thanks, i got it now.
For example: If you use filesperset 1 than only 1 file will be included in a backupset.If you have 4 tablespaces it will > create 4 backupsets. XE per default has system, sysaux, undo, users - 4 tablespaces. In addition if you open > channels then 4 backupsets are generated.I didnt change this value so i think default value is 3, coz created new tablespace and even add new datafiles and always got 3 backupsets. I read in oracle document that:
Specifies the maximum number of input files in each backup set. If you set FILESPERSET = n, then RMAN never includes more than n files in a backup set. The default for FILESPERSET is the lesser of these two values: 64, number of input files divided by the number of channels. For example, if you back up 100 datafiles by using two channels, RMAN sets FILESPERSET to 50.
RMAN always attempts to create enough backup sets so that all allocated channels have work to do. An exception to the rule occurs when there are more channels than files to back up. For example, if RMAN backs up two datafiles+ when three channels are allocated and FILESPERSET = 1, then one channel is necessarily idle.+
So i can manage the number of backupsets, right? How much should i have? many files with min sizes or some files with big size?
Hi Hemant K Chitale,
Ok, thanks a lot. I didnt know that i can create controlfile in FRA. What is the benefit of this strategy?
controlfile backups / autobackups would be in BACKUPPIECE.but in another folder and not with backupsets folder, right? coz my database backupsets are in ...\FRA\XE\BACKUPSET\ and backupset of controlfiles are in ...\FRA\XE\AUTOBACKUP\
regards and thanks,

Add datafile dataguard from physical RAC to standby RAC
Hello we have a 3 node cluster RAC 10g on the primary and RAC 10g on the standby.We use as db storage ASM wich is configured over raw devices and file management omf.The same groups DATA and FRA on both servers.STANDBY_FILE_MANAGEMENT is manual.
We need to add a datafile on the primary safely.Can you offer me some ideeas?
Thank you!Hello;
Change STANDBY_FILE_MANAGEMENT to "auto" before you add the file and then leave it set to "auto". ( set this to AUTO on both Primary and Standby )
STANDBY_FILE_MANAGEMENT enables or disables automatic standby file management.
If you leave it set to MANUAL you may create unwanted file in $ORACLE_HOME/dbs and cause issues with the MRP process.
Best Regards
