How to backup oracle RAC filesystem

Hello,
May anyone in this community might help to answer on my inquiry on how to backup oracle RAC filesystem. There are many backup features available out there i.e: RMAN, hotbackup etc but the way the backup is working is RMAN will backup and stored the db file in the filesystem. I presume the filesystem also need to be backed up in order to avoid the filesystem corrupted etc
Regards

Hi,
Always welcome ..
when you want to take backup of all the database components of RAC, that's why i advised you to include the all commands in your backup strategy, so that in any case your any components doesn't work , you can restore the particular one .
One thing you can do , you are running your RAC environment on Vsphere , in that case , create a backup plan with the client and your IT team to take backup of whole environment by creating snapshot of Vsphere along with backup plan mentioned by me in above reply  , so in worst scenario your whole environment can be restored .
I have seen that if RAC environment is running on VMware , then its best to take snapshot of whole machine which should be defined in backup policy apart from normal backup of database.

    Hi there,

    /u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@vvsms  log /home/oracle/log_rman/vvsms.log appendThis line can be your problem.
    As this database is a RAC and your are using a service with load balance "vvsms" and "/home/oracle/backup/vvsms" is not a shared location. RMAN is starting a session on Other node where "/home/oracle/backup/vvsms" does not exists.
    Try change it :
    /u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@vvsms  log /home/oracle/log_rman/vvsms.log appendTo this (using Easy Connect Method):
    /u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@localhost:1521/VVSMS  log /home/oracle/log_rman/vvsms.log appendWhere:
    localhost: your local node
    VVSMS : is the service of database
    Also check if "/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/sqlnet.ora" have configured the line "NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)"
    P.S : When RMAN start a session it show where is logged, check on logs what instance RMAN was logged.

  • How to backup Oracle Database Single Instance using RMAN

    Folks,
    Hello. I am using Oracle Database Server 11gR1 with Operating System Oracle Linux 5.10.
    I understand how to backup database instance in SQL Server with Windows. But don't really understand how to backup database instance in Oracle with Linux.
    I have done Cold backup and Hot backup for the database instance HRCS90 but both get the same error message.
    Cold backup is below:

    While the database instance HRCS90 is startup, I do hot backup using the same commands and get the same error message with above cold backup.
    My question is:
    Can any folk tell me the specific steps (command by command) to backup a single database instance in Oracle using RMAN ?
    Thanks.

    Folks,
    Hello. Thanks a lot for replying. My database instance named HRCS90 is going to be backed up. My backup directory is /backup_Database_Instance_HRCS90.
    If database in open state, we must back up in archive log. If database in mount state but not open, we can back up in noarchive log.
    I have tried to back up HRCS90 in archive and noarchive log when database in mount state but not open as below:
    SQL>startup mount;
    SQL>exit
    [user@linux bin]$./rman
    RMAN>connect target;

  • How to install Oracle RAC using 11gR2 on Win 7 32 bit from scratch?

    Hiii,
    I am a fresher and I have a win 7 system 32 bit with oracle 11gR2.
    I want to install RAC using two or more servers but I dont know too much about it.
    I tried to search on google but all they are giving information in pieces(for win 7) or about Linux(Please tell me why its all Linux everywhere not windows).
    Please let me know if there any site where I can find step by step installation from scratch.
    What are basic requirements(/software if needed).
    Thank you.

    Hi,
    First of all forget about Windows!! Oracle is mainly designed for Linux systems. Oracle runs as real multi-process on Linux machines whereas on Windows it runs as a single process with multi-thread.
    Memory usage - huge pages,single CPU run queue, dnfs, storage systems... etc. lots of concepts exists.
    Besides Windows is one of the most poorly designed operating systems, you should use it only to watch cute kitten movies on youtube... Believe me, you wouldn't want to learn Oracle on Windows...
    So, install virtualbox and then setup Oracle Enterprise Linux on it as a first step... By the way you have to deal with DNS server for release 11.X, RAC, you may start with 10g for now.
    ORACLE-BASE has all the installation steps explained detailly, search for "oracle base rac install" on google.
    I also explained on my blog, but it is a little bit advanced installation using ZFS storage simulator. DNS server installation is also explained:  http://ilkertaysi.com/2013/11/11/oracle-rac-installation-with-zfs-storage/

  • How connect to oracle RAC via the RSG using port forwarding

    Hi all,
    I got a problem trying to connect to oracle RAC via the RSG using port forwarding .
    on command line i sue to connect :
    sqlplus 'username/password@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=firstRACnode)(PORT=1521))(ADDRESS=(PROTOCOL=tcp)(HOST=secondRACnode)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=MSDP)))'
    but when using port forwarding i forward the port 1521 to a local port and make ssh to the DB node ( as normal with other nodes but not RAC) but it never work with me for this situation
    can any one give me a help ifthere is any changes should be done on the server side , or if any one faced such a problem and found a solution
    Thanks,
    Prathap.

    Step 1
    Create a ssh tunnel from local machine to remote db server. Forward any local port (should not be a well known port or a port in the private/dynamic port range) to connect to the database server's listener port. If the ssh tunnel is into the db server itself, the connection (port forwarding) can be on localhost (as the Listener should be listening on it). Alternatively use a public IP of that db server.
    Example (using OpenSSH on Ubuntu 9.4):
    Local server port 1527 tunneled to port 1521 on database server 192.168.0.100 using o/s account johnd (we connect to port 1521 on db server via 127.0.0.1):
    ssh -X -f -N -o ServerAliveInterval=3 -L 1527:127.0.0.1:1521 [email protected]
    Step 2
    Run sqlplus and connect to the local fowarded port on localhost, using the applicable connection settings (e.g SID/Service Name, etc).
    sqlplus scott/tiger@"(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1527)) (CONNECT_DATA=(SID=orcl) (SERVER=dedicated)))"Note that the Listener must not hand our connection off - as the case would be when using RAC for example and connecting via a Service Name and not a SID. We need the Listener that accepts our connection to immediately hand us over to the database instance (via either a dedicated server or a shared server dispatcher process).

    Hi,
    Could anyone please tell me about a full script that will backup my Oracle XE "Express" database. I have user schema and it has tables with data and I want to backup them. I hope someone tell me how. I want to do it inside a button so it can be easy for me to just press on button and it will continue its job. Thank you very much for your help.
    Any method is appreciated from you. So I just need the way that I can do it. In Oracle forms I used to use exp but in C# I don't how.

    ok
    Even this is ODBC forum, you could check for $ORACLE_HOME/bin/Backup.bat ... analize that script. You could call it from c# with Process Class, and process.startinfo.

  • How to disable Oracle RAC configuration.

    Hi,
    I have a system running on a RAC configuration (two machines and a shared SAN) I have been looking extensively for any documentation on how to dismantle (safely, i.e. best practise) the rac configuration.
    I don't want to loose the database and want to keep one of the instance running and servicing the database, but I want to remove all RAC/Cluster references and remove the other machine.
    Is there any note/ documentation anywhere on how to do that so that the database/instance will be running afterwards with no knowledge on having been in a RAC config before or has someone done that ?

    Want to know how can I convert a rac database to a non-rac.

  • How to backup Oracle Applications

    Hi
    I am new at Applications and I am wondering what are the best practices in backing up Applications.
    Are there any documents available about this?
    Please advise
    regards
    Snjolaug

    hi Snjolaug and jill
    the backup strategy depends on the situation , you can backup all the three directories. In the event of crash you can install without database.
    import your backed up database and then overwrite on the three $TOP directories with the backed up directories.
    you have everything back normal.
    Else
    optionally you can backup database as normal , and backup just $APPL_TOP , $COMN_TOP . since patches when applied alters some files in $COMN_TOP.
    Bottom Line is database and $APPL_TOP backup is very important as database contains AOL and $APPL_TOP contains product directories.
    for clone tooo, the above procedure can be followed
    pls get back with your comments.
    NOTE: I appeal to all APPS DBA's to post their experience here as it helps other DBA's

    Regards,
    Hi,
    HACMP is vendor clusterware (IBM technology) for cluster it is High Availability Cluster Multi Processing. When installing Oracle RAC it must installed on top of vendor clusterware.
    HACMP comes in play when you use raw logical volume and it needs to be managed by HACMP.
    Since 10g it is not mandatory to use HACMP so you can choose not to use it and let Oracle manage all the cluster services
    Hope this helps
    Cheers
