Oracle 9i RAC datafile restore

Hi,
In our 9i RAC production database one of the mount point crashed and we lost few datafiles. But we have a DR site with the same DBID and the DR is in sync with production, Can we use the datafile from DR and put it in the production and do recovery?
Thanks in advance.

If by DR you mean a physical standby database for production, yes you can. Just make sure all the redo and archive logs are accessible on the production DB.

    Do you have backup of the Prod database. If yes then you can use the backup to restore the datafile and do the recovery.
    If using datafile from DR to restore the database is not tested, I will not use it in Production.

  • RAC RMAN Restore/Recover

    Hi folks,
    I have some doubts about the PATH to disaster recovey with RAC and RMAN.
    In this case I have just the RAC without data guard/streams, just only a single rac with two nodes.
    The hypothetical scenario is:
    One database using ASM (database name orcl) , two inatances in two separated servers (nodes serv1 and serv2) and two instances ( orcl1 and orcl1).
    In this scenary I lost everything, and just keep the backups of: spfile, controlfile, database and archives.
    So the steps to recovery is (using serv1):
    1- Create the cluster (install clusteware, create CRS/Vdisk, create ASM instance)
    2 - Just install the oracle files in all nodes serv1 and serv2, but don't create the instance orcl1 and orcl2.
    3 - restore/recover spfile - rman
    4 - restore/recover controlfile - rman
    5 - restore/recover database with until clause - rman
    After these steps the instance orcl1 will be restored by RMAN in the serv1 and the database orcl was created in the ASM.
    But, please correct if I'm wrong, the instance and database will not be registered in CRS (RMAN not register the instance).
    So I need to registry the instance and database with srvctl, doing:
    1 - create PFILE in serv1 for orcl1 (that point to SPFILE in ASM) and ORAPWD file.
    2 - add the database orcl to CRS
    3 - add the instance orcl1 to CRS
    4 - add the dependency about ASM and orcl1 from the node serv1 (using srvclt)
    But after this I have the instance orcl2 in serv2 to create.
    Just the instance, because the binaries already installed and the database was already created.
    To complete I need to do the steps:
    1 - Copy/Create PFILE for instance orcl2 in serv2
    2 - add the instance orcl2 to CRS (using srvctl add instance)
    3 - add the dependency about ASM instance (that exists in server2) and Instance orcl2 from the node serv2 (using srvctl)
    4 - create PFILE and ORAPWD file.
    The question is, RMAN will registry the instancie and database in CRS?
    Another question, the RMAN will create PFILE and registry all instances of the original cluster?
    I believe that not for two questions, correct?
    Exists another path to restore/recover the RAC in this scenary?
    The version in this case is 10Gr2 and 11Gr2.
    Thanks.

    The question is, RMAN will registry the instancie and database in CRS?NO.. You will need the SRVCTL for registry services.
    Another question, the RMAN will create PFILE and registry all instances of the original cluster?No... RMAN perform restore SPFILE only.
    I believe that not for two questions, correct?
    Correct.
    Exists another path to restore/recover the RAC in this scenary?
    The version in this case is 10Gr2 and 11Gr2.You can skip a few steps above by doing this:
    After installing Oracle Clusterware / RAC
    You will configure the network via NETCA.
    You will create and configure ASM with DBCA.
    To skip all the setup steps the Database (orcl) in Oracle Clusterware, you will create a database via DBCA with the same DB_NAME (orcl) of the database that will be restored.
    The DBCA will configure the database with all the dependent services of the Clusterware including TNSNAMES.
    Finished creating the database, all services should be configured, you will connect to ASM via asmcmd and drop (spfile, controlfile and datafiles), now just perform the restore (SPFILE,CONTROLFILE and DATAFILES) via rman.

  • Oracle 10g RAC using ASM - Storage Issue

    I’ve an issue related to Oracle 10g RAC.
    I’ve 2 node cluster each being Dell 2850 Server with RHEL 4.0
    I’ve EMC CX300 SAN storage with following partitions
    /orasoft     10 Gb          OCFS2 File system
    /oracrs          2 Gb          OCFS2 File system
    /orabackup      100 Gb          OCFS2 File system
    The datafiles are on ASM which is not directly visible in OS.
    I’ve common Oracle Home installed in /orasoft/db_1 which is shared by both nodes in cluster.
    I’ve faced an issue recently related to EMC storage.
    The /orasoft partition displays 1.4 Gb space available using df command.
    With both nodes sharing the common Oracle Home (/orasoft/db_1), when ever I try to touch a file I get an error as No Space left on device. I’m unable to start any service with the same reason.
    Is this setup correct ??
    Can anyone help me with this storage issue ??

    Need a clarification here...what do you mean by "Storage System"...do you mean a server/node or the SAN storage system. If you are referring to a server/node's local storage, then it would NOT be possible for use by RAC, since the disk space has to be shared among the nodes.
    Here is what you can do:
    - Create two partitions/devices (for example Disk_1 and Disk_2) in the SAN storage
    - Create a ASM disk group which would mirror Disk_1 to Disk_2.
    Again, please note that the partitions have to be visible and be accessible read/write from both the nodes/servers.
    HTH
    Thanks

    Hi,
    If you create a new diskgroup you may be to add the same diskgroup to parameter file or spfile and which will be needing down time.
    sugestion: Instead of creating new diskgroup you should to add disk to existing group.if you add asm disk to existing group your all problem will be solved and Oracle itself will be managing all.And than i am sure no need to add entry in the parameter or spfile like +db_create_file_dest=.....

  • Solaris 10 + Oracle 10gR2 RAC question

    Hello everyone
    Has anyone come across the case where the CRS services of Oracle cause
    the public interface to get turned off and then restored at random
    time intervals? To elaborate, we have a 2 node cluster database.
    Solaris 10, Oracle 10gR2 RAC with patch 10.2.0.3 applied. No SUN
    clustering is involved. When the cluster software is down (nodeapps,
    asm, database instances all down) /var/adm/messages show nothing. When
    we start nodeapps on the 2 nodes(thus initiating some form of
    communication between the nodes), at random time intervals we get
    "interface ce0 turned off and interface ce0 restored" in /var/adm/
    messages. When we check the status of the RAC, we see that one node's
    vip has been assigned to the other. This on/off behaviour of the NIC
    can be eliminated only if we continuously PING it from a another
    client in the network.
    As a matter of fact, the RAC and the RDBMS work perfectly when we keep
    pinging the 2 nodes from an other client on the network. We even
    managed to run a long batch job, distributed on cluster managed
    services on the 2 instances, and it completed after 9 hours without
    any problems.
    Does anyone have a hint on this behaviour? Is there some sort of
    timeout for the network cards? Some power saving features? Googling
    around I came across the new Containers feature available on Solaris
    10. Is there a way that I can verify that either RAC or the RDBMS is
    running in "container" mode ( since the solaris and Oracle
    installation was not performed by me)? Any other ideas?
    Thank you for reading

    Im an Oracle guy - not the SA type -
    But on ours - the SA configured this cluster incorrectly. We use veritas. instead of making ipmp groups for the interfaces - he built the cluster according to veritas docs. That is - he has two publics - on difference interfaces and different privates on different interfaces. oracle can only two interfaces - no matter if its a ipmp group or a device name. one is used for private- the other is used for public - So sure the veritas cluster filesystems will survive - but the Oracle Cluster will not - nodes will reboot -
    Is your system set up incorrectly as i described above? if it is - a quick test would be - turn down the other interfaces - and only leave the two interfaces you mention above up that you configured for Oracle CRS
    This other sharp sa was able to go through the arp table and see duplicate IPs - and the routing was attempted via an interface that oracle doesnt see. You can not define two different interfaces public - and two different interfaces for private -

  • Blockrecover but full datafile restore + ORA-01193

    Hi,
    We have a proplem, here is a short sescription:
    We have corrupt blocks, how can we solve this problem? Blockrecover uses full datafile restore and finally fails with ORA-01193.
    Here is a detailed description:
    We have a 330GB datafile (bigfile tablespace) with 46 corrupt block.
    DB version 10.2.0.4, Oracle linux, we use ASM.
    We would repair these blocks.
    V$DATABASE_BLOCK_CORRUPTION after "backup validate check logical datafile 7" :
    FILE#     BLOCK#     BLOCKS     CORRUPTION_CHANGE#     CORRUPTION_TYPE
    7     16872378     1     0     FRACTURED
    7     16872408     40     0     CORRUPT
    7     16872379     5     0     CORRUPT
    The result is similar by dbv.
    We have archivelog mode and backupset created by rman command:
    backup as compressed backupset incremental level 0 database;
    All of the corrupted blocks are in 1 LOB segment.
    We copied the LOB segment, only 5 record cannot be read.
    The corrupted LOB segment (and table) was exchanged by the copied (not corrupted) data, so users can work.
    We remained the corrupted LOB segment in the database, but it is not in use.
    I started blockrecovery by command:
    BLOCKRECOVER DATAFILE 7 BLOCK 16872378,...,16872447;
    The listed blocks are same as in the V$DATABASE_BLOCK_CORRUPTION, so the command could be:
    BLOCKRECOVER CORRUPTION LIST;
    The database was opened during blockrecocer and the datafile 7 was online.
    A line appeared in the V$SESSION_LONGOPS with:
    "RMAN: full datafile restore"
    The restore was more than 4 hours, and finally it is failed with error:
    Starting blockrecover at 29-AUG-12
    starting media recovery
    ORA-01193 file % is not the same file seen at start of recovery
    Based on V$SESSTAT there were lot of physical read but only some physical write.
    Maybe full datafile read, and only corrupted blocks was changed, but I didn't check it exactly.
    We retried blockrecover with only one block, but the result was same: it failed after 4 hours with ORA-01193.
    We retried the blockrecovery on a mounted but not opened database, and the datafile was offline:
    SHUTDOWN IMMEDIATE;
    STARTUP MOUNT;
    ALTER DATABASE DATAFILE 7 offline
    BLOCKRECOVER ...
    The result was same: it failed after 4 hours with ORA-01193.
    rman backup failed with error:
    RMAN : ORA-19566: exceeded limit of 0 corrupt blocks for file %
    After set maxcorrupt, rman backup ran successfuly
    SET MAXCORRUPT FOR DATAFILE 7 TO 46;
    Based on our current info, these workaround seems best for us:
    - rman "set maxcorrupt"
    - DB_BLOCK_CHECKING=FULL
    - drop corrupted (but copied and not used segment)
    - wait until corrupted blocks will be reallocated (checking it periodically by dbv)
    - set maxcorrupt to 0
    Our questions are:
    *1. Why oracle uses "RMAN: full datafile restore" during blockrecover?*
    Why needed to read the whole datafile?
    One of the advantage of blockrecover should be the relative small IO, and fast restore.
    I found only 2 results in google for "blockrecover" and "RMAN: full datafile restore".
    (One of the findings was in this forum, but it was no answer for our problem)
    *2. ORA-01193: file is not the same, but why?*
    It is strange on opened database and online datafile, because other advantage of blockrecover should be the online recovery.
    But it is more-more strange on closed(mounted) database and offline datafile. Only the rman blockrecover could change this file.
    I found only 3 results in google for "blockrecover" "ORA-01193"
    I found only the oerr output in google for "ORA-01193". But what does it mean? Only the rman blockrecover could change this file.
    Cause: A different copy of the file was accessed the last time media recovery looked at the file header. A backup of the file was restored or the meaning of the file name changed during recovery.
    Action: Ensure the correct file is available, then retry recovery.
    *3. What else can be do to repair these corrupt blocks? What can we do for success blockrecover, or is there any other idea?*
    Other infos:
    - DB_BLOCK_CHECKING was false, but we changed it to FULL to avoid the subsequent corruptions
    ALTER SYSTEM SET DB_BLOCK_CHECKING = FULL scope=both
    - DBMS_REPAIR cannot detect the (out-of-line) LOB segment errors.
    - rman SET MAXCORRUPT is not a "calming" solution
    - When I read on internet, when we drop the corrupted LOB segments, the blocks will remains corrupt.
    And the block will be repaired/formatted only when a new segment will allocate these blocks.
    Based on metalink 336133.1, we can ensure the new allocation by fill the datafile with dummy data until the corrupted blocks will be allocated.
    But this is a very IO intensive task.
    - full recovery
    very IO intensive, we try to avoid it.
    Thx: lados.

    Hi,
    other infos:
    We use ASM, and one of the disk is dropped and added after the last full (incremental level 0) backup. Can this premise causes the slow restore (something physical storage info is changed), or the ORA-01193 error (file % is not the same file seen at start of recovery) ? I don't think that a full db backup is needed after ASM disk drop/add/rebalance. But we tried a full backup (this was when the corrupt block first appeared with ORA-19566).
    I found only one finding in the metalink for ORA-01193. The oerr reference (cause,action). It would be strange, if nobady else had problem with this error.
    Thx: lados.

  • Oracle 10g RAC installation on HP-UX 11.31 for SAP ERP 6.04

    Dear experts,
    We are trying to install SAP ERP 6.0 EHP4 with Oracle 10g RAC on HP-UX 11.31. Please note that, We are using VERITAS cluster filesystem (CFS) for this purpose and not HP-UX ServiceGuard ClusterFileSystem.
    *As per SAP procedure, we have installaed plain plain SAP system with single instance Oracle (ref: Configuration of SAP NetWeaver for Oracle Database 10gRAC guide). Now we are first trying to install Oracle Clusterware (CRS) and then we will install Oracle RAC software. Is this procedure right?*
    Which file (and its path) we have to use for CRS installation and its patch? Is it runInstaller under /oracle/stage/102_64/clusterware? With this file we can install CRS 10.2.0.1. Similarly for Oracle RAC, which files we are supposed to use, i.e for installation and patch upgrade?
    Also can we use clusterware package available from Oracle directly in the SAP environment?
    We tried to install CRS with runInstaller while running Configuration Assistant after root.sh script.
    The following commands are failing in Configuration Assistant:
    /oracle/CRS/102_64/bin/racgons add_config erpprdd1:4948 erpprdd2:4948

    2nd commands o/p: PRIF-12: failed to initialize cluster support services
    3rd commands fails in every check
    Please suggest the solution and expecting answers to the above mentioned questions.

  • Oracle 10g RAC

    Hi All,
    I am a research student currently struggling to install Oracle 10g RAC on Windows OS.What i understand about a Oracle RAC database system is that it involves a configuration of multiple hosts or servers joined together with a clustering software and accessing the shared disk structures.What i also understand is that i need a CRS provided by Oracle for a Windows or Linux based RAC installation.
    What i don't understand is for a Two node RAC system do i need a Third machine which has the shared storage device.If yes do i have to install a copy of Oracle 10g Enterprise Edition and CRS on the shared storage device moreover do i need to install a copy of Oracle 10g Enterprise edition on each of the nodes or just the clusterware is enough.

    Hi Salil
    No, you do not need a third machine. You can even setup RAC as a single node on one machine! What you do need is to have some sort of cluster aware file system. Try looking at OCFS on Windows in your case.
    If you are interested in a Linux example please have a look at the examples at http://ocpdba.net/oracle9i_rac/cheaprac.html and http://ocpdba.net/oracle10g_rac for an OCFS implementation I am working on.

    1. Check the Details panel on the Configuration Assistant Screen to see the errors resulting in the failures.

    Hi all,
    I have a question about Oracle RAC and network interface.
    We're using Oracle 10gR2 RAC with two nodes on Linux Red Hat.
    Let's assume that the public network interface goes down.
    I would like to know what happens with existing connections
    on node with network interface with problems.
    Are connections frozen, actives?
    Can the users continue to use theses existing connections using the another node of RAC?If the interface is down? what do you think? All connections to this node will die. How does your application handle fail-over, does it attempt to reconnect or just have a complete application failure?
    You should spend some time in a test lab where you can test this stuff for yourself. Read the documentation and there are tons of sites out there that purport to have all of your RAC/TAF/FAN/FAF questions. - I would read and trust the documentation first.

    I know that the listener goes down and any other connections is allowed.
    Thank you very much!!!!

    You know its not certified?
    My first thought when I read the subject of this thread, and before reading what you posted, is that you've either done no research on RAC or didn't understand what you've read.
    You can create a RAC cluster using any operating system certified by Oracle.
    But the operating system is the least important part of creating a cluster. The questions you need to be able to address are:
    1. What is your solution to created shared storage?
    2. What is your solution to create the cache fusion interconnect and VIPs?
    If you don't have an answer to these questions you can not build a RAC cluster.
