• Backups of the DSO and recovery in the ASM failure.

  If the ASM instance fails and RMAN backups are on ASM diskgroup, can I still recover my database? What happens if the diskgroup goes to zero out or something like:

  Are my backups?

  Yes. I don't see a big difference (regarding the consequences) to "rm - rf '." Binary zeros are not a valid backup.

• Clarification on Metalink 333257.1 - backup on an Instance of the ASM

  Hello!
  
  In the document, it is said that no backup copy of the DSO is necessary. However, s/n could follow on the amendment of certain information ("they can keep record of the init.ora asm_diskgroups, asm_diskstring and parameters settings").
  
  Could someone tell me exact SQLs that can retrieve such information? Any doc, link, "best practice"?

  It's really as simple as that. You back up all your DATA with rman via your 'normal' database instance If you lose your installation asm (ORACLE_HOME) but not the discs of data, all you need to "restore" your system would be to reinstall the oracle software, start the asm instance and point to the data disks. The only things really, you define in asm is the discovery-path/diskstring and starts to ride (which is stored with a bunch of default settings for most in your asm init or spfile) so that's all you need to backup.
  If you lose data disks, you must restore the data from your backup rman.

• Backup RMAN ASM filesystem

  Hi all
  
  I have an rman backup (datafile and controlfile) who got caught in an instance of the DSO (not a RAC) ORACLE 11.2.0.2 on a server Linux, now I want to restore the backup into a new database under windows/Linux OS with storage system (single instance RDBMS) General files instead of ASM.
  
  Is this possible?
  
  I can restrore an rman backup ASM in a mechanisim of storage of file in a new server system?
  
  Please clarify my question.

  Hi Levi,

  Thank you for your invaluable script and the blog.

  can you tell me about this query:

  I have an RMAN backup, drawn from the ASM and the backup is the database and controlf backup file that contains the data files and controlfiles.
  Now I need to restore this on my system and here I only use ASM or archive log, I use only one instance in any database log mode archive.

  I restored the backup controfile RMAN control file.
  Before you restore the control file, I checked the pfile orginal of the backup of database with parameters such as
  "db_create_file_dest."
  "db_create_online_log_dest,"
  "db_recovery_file_dest_size."
  "db_recovery_dest,"
  'log_archive_dest '.

  Since I'm not gng to create a database in any mode of newspaper archive, I do not use any of the above parameters and created a database.

  Now my question is:
  If I restore the database and the data file get restored and after rename all the log files, the database will be open.

  I want to know if this is good or bad, and the database will work as he previously worked. Or need to create the db_file_recovery and also other settings for this database.

  All parameter:
  All these settings should reflect your current environment, any reference to the old environment must be changed.

  All file system used:
  No matter what you use the file (datafile/redolog/controlfile/archivelog/backuppiece) file system are created on binary Format that depend only on platform. Thus, the file binary (for example datafile) have same format and content on the device gross, ASM, ext3, ext2 and so on. Thus, for the database, it is just a place where the files are stored, but the file are the same. ASM has a different architecture of the regular file system and must be managed differently (IE with RMAN).

  On the database:
  Given that your database files are the same even different file system using what you need is rename your files from data/redofiles on controlfile during the restoration, the redo files will be recreated.
  So, no matter if your database are noarchivelog or archivelog, in the same way you do a restore on ASM is the same way to restore the regular file system. (just rename the database during restore controlfile)

  On blog post 'How to migrate all files on ASM to no - ASM (Unix/Linux)' is suddenly of system files to another folder. But you can change the script used for restore purposes;

  ## set newname tell to RMAN where file will be restored and keep this files location on memory buffer
  RMAN> set newname for datafile 1 to ;
  
  ### swich get list of files from memory buffer (rman) and rename on controlfile the files already restored.
  RMAN>switch datafile/tempfile all ;
  

  With mounted database, use this script below:

  I just commented on three lines that are not necessary in your case.

  SET serveroutput ON;
  DECLARE
    vcount  NUMBER:=0;
    vfname VARCHAR2(1024);

  After the restoration, you must rename your redologs on controlfile to old location to the new location:

  for example

  ##  use this query to get current location of redolog
  SQL>  select group#,member from v$logfile order by 1;
  
  ## and change from  to 
  
  SQL > ALTER DATABASE
    RENAME FILE '+DG_TSM_DATA/tsm/onlinelog/group_3.263.720532229'
             TO  '/u01/app/oracle/oradata/logs/log3a.rdo'  
  

  When you change all the redolog on question below controlfile command:

  SQL> alter database open resetlogs;
  

  PS: Always follow the database in real time using the alert log database file.

• RMAN to the ASM and network file system

  Hi all
  
  I use Oracle RAC 11 g R2 + ASM.
  I am new to RMAN, but I am trying to build daily tasks to do below:
  
  1. backup of my database to the FRA located on ASM diskgroup + FRA.
  2. at the same time I want to save my database for Network File System (NFS) to be taken by system administrators to an archive location that I can't access. Since according to my knowledge can't copy files to ASM for outside... so for this I'm planing to use the command format of the NFS mount point.
  3. on daily basis in the NFS file will be taken by a work (that I am not responsible for) to the Archive, and then it will be purged from this location.
  4. I am planing to have my windows of 15 days retention strategy.
  5. on every day, I am planing to cross check my backup and then delete the expired so that taken from NFS in the journal of the archives is deleted.
  
  The RMAN I am planing to run it on a daily basis are:
  

  backup incremental level 0 cumulative device type disk tag 'FULL_DB_INCR_LV0' database; -- this will be to the default location (+FRA)
  backup incremental level 0 cumulative device type disk tag 'FULL_DB_INCR_LV0' database format 'NFS/oracle/backup%U';--another copy to be taken to the archive location
  crosscheck backupset;
  delete expired backupset; -- this will delete the backups taken to the Archive location

  Now my questions:
  
  1 what good solutions? take account of the fact that I need backup on the file system of the operating system so that the jobs of system administrators take the backup of their archives.
  2. If a backup is needed, I use CATALOGUE START WITH to recover and then recover.
  3. because my retention period is 15 days, and the backup in NFS files will be deleted on a daily basis, so this retention will apply for backups in ASM, is this a problem?

• Cold copy on the ASM database. Please notify

  Hello
  The configuration is:
  HP Itanium
  Grid/ASM 11.2.0.2
  RDBMS 10.2.0.4
  
  I have a 4 TB database. Application needs three test cases.
  Each test should use the same sets of data. So I asked me to copy the database from 4 TB to a different diskgroup on the same instance of the DSO.
  Start the database using the just copied the controlfiles/datafiles/redologs.
  Then application would run a few tests.
  Then I should delete the copy of the database and repeat the steps to create a new copy of the original database of 4 TB.
  
  I need to find an efficient way to copy the database from 4 TB to the new on the same asm diskgroup.
  
  I can't use the flashback database option.
  The database of 4 TB can be closed during the copy.
  The storage is fast
  
  My idea is to copy data/controlfiles/redolog files using the cp asmcmd command and then rename files from data/redologs.
  
  I don't know if the current copy of running in parallel is better then copy files one by one.
  I could also use backup rman as copy, but I guess that the result would be no different in terms of deadlines.
  
  Any suggestion?
  
  Thank you, man

  Hello

  The best option is to use RMAN to perform this work.

  Philippe Florent showed how to do this without using the backup image database on the file system... I upgraded to customers who use the ASM.

  I understand what you say, I have created a disk of asm with 500 MB of size using asmtool, so I can't resize using asm instance.

  1. What is the use of asmtool-added option, we can add an existing using this command drive space?

  This isn't for adding space, but it adds the label to the disk partition...
  asmtool - add \Device\Harddisk1\Partition1 ORCLDISKASM0
  >

  2 can you please explain this more, * it could be increased if you already held 300 total asm 500 disk space *?

  Think like OS, you have created a 10 GB partition for disk D:\ example. And now, you create files/folders with size of hugh (as some movies ;)) to drive D:\, so eventually your drive D:\ will fill. This is the case even with your asm disk, once you have used all your available space of the asm disk (that you created through asmtoll), you can not increase.
  By asmtool - create D:\Asm_disks\disk3 500, you assign the total size to 300 from the asm disk. Just as you add 10 GB partition for OS...

  You come to the backup from my point of view: it could be increased if you already worked 300 asm disk space total 500

  I have created the disk with the following text:
  asmtool - create 500 D:\Asm_disks\disk3 > size is 500

  I create diskgroup with
  SQL > create diskgroup DB 'D:\Asm_disks\disk3' size disc 300; > Here I wll use only max 300 size of 500 total. So once I get to the threshold of 300, I can increase the asm disk up to 500.
  As
  SQL > alter diskgroup DB resizing disk "D:\Asm_disks\disk3' size 500; > Increasing up to 500

  Default if the clause you SIZE omit while creating a diskgroup, asm then disc occupies all the available space of the device that you have created by asmtool

  >

  3. What is meant occupation here, not here where we can control the right of occupancy?

  We can control as I explained.

  oracleasm version came not in rpm-qa output may be because it is part of the Oracle Linux kernel. But the 2 components above are not

  = Environment details end =.

  We have a 2 node RAC cluster.

  We wanted to add 2 LUNS to our data Diskgroup and asked team storage available to both nodes of the cluster.

  After that they provided, the Linux Admin scanned the LUN and powerpath device names were generated. The powerpath device names like SCSI logic unit number names are incremented sequentially. Because, two additional powerpath LUN used to Node1 to a local file system, the names of powerpath were incrementing differently in the two nodes.

  Thus, for the same LUNS emcpowerpath names differed in Node2. Linux Admin did not notice this difference. And he told us the names of newly added from Node1 LUNS powerpath that have been

  / dev/emcpowerv

  / dev/emcpowerw

  But in Node2, the same LUN were appointed

  / dev/emcpowert

  / dev/emcpoweru

  The DBA guess powerpath name these 2 LUNS will be same on Node2, label the discs to help

  oracleasm createdisk DATA17/dev/emcpowerv1

  oracleasm createdisk DATA18/dev/emcpowerw1

  After marking in node 1, the DBA ran scandisks in Node2. But while the oracleasm scandisks in Node2 is running, it does not seem to/dev/emcpowerv and/dev/emcpowerw in Node2. Instead, ASMLib is smart enough to read the LUN ID in Node1 and search devices powerpath with the same LUN ID and labels as Node1. What's it like in Node2, / dev/emcpowert is labeled DATA17 and/dev/emcpoweru is labeled DATA18 correctly, as shown below.

  Node1

  Node2

  DATA17

  / dev/emcpowerw

  / dev/emcpoweru

  629:

  DATA18

  Confirmed using the oracleasm querydisk Pei/dev/emcpower < x > .

  During labelling using the oracleasm createdisk , since we use the LUN name I always thought that asmlib dealt only with the names of devices (Powerpath name in this case). I didn't know that ASMLib treats ID LUN. If ASMLIB faces in LUN ID internally, then you don't need to have the same name for a particular LUN for disks shared in different RAC nodes? Right?

  ASMLIB contains 3 packs. Oracleasmlib, which is distributed under a license of Oracle user space and is not part of the standard GPL software distribution. Oracleasm-support, which is in the standard repository and kernel driver of Oracleasm, which is included in the core Oracle UEK only or distributed by Red Hat to RHCK kernel. The subsequent RHCK driver requires a Red Hat subscription. You need all 3 installed packages.

  ASMLib doesn't care to the SCSI ID or device names. When you configure a device to ASMLIB, he writes a header special disk in the device, the command scandisk read and identify a device. ASMLIB devices are populated under the tree of device/dev/oracleasm and found by ASM using the default ORCL: device chain.

  Don't forget that ASMLIB does not work with multiple devices and if you use DB-Multipath or EMC Powerpath, you need to blacklist the physical devices so ASMLIB will use powerpath or multipath device instead. Otherwise there will be no failover devices like ASMLIB will simply use the first device found and ignore the other. Check the following:
