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 ?
Thor Hjalmar.

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

  • 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.

  • Configure Oracle DB Adapter in Oracle RAC configuration

    Oracle RAC uses Service name rather than SID and Oracle adpater only accepts a URL string in sid format.  How can a connection be defined for a RAC environment?

    Thank you.  The solution for configuring a Tidal adapter that uses Oracle RAC is to expand the URL connection string where the Service name can be defined.
    Standard defined connection string:
    jdbc:oracle:thin:@hostname:1521:sid
    Connection string for Oracle RAC:
    jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=hostname)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=servicename)))

  • 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).

  • Unable to make SSH to another node in AIX for Oracle RAC Configuration

    Hi,
    After creating RSA Keys on both node when I try to scp authorized_keys file from one node to another, it give me the error of Connection lost and then connection closed by 'Machine Address'. SSH services are running on both node and I'm able to do ssh from root user but this happened with Oracle OS user account. This seems that sencond machine refuse to make connection. Kindly help me why is this happening.
    I'm doing this on AIX 5.3. Your help will highly be appreciated.
    Regards,
    Abbasi

    Schavali, you are right this question is acutally has nothing to do with Oracle but the thing is that this issue arises during the configuration of RAC and we are unable to find the reason yet. I think there is problem with key genration however, I'll try to do this. by configuring sshd_config file and then will share the result.

  • How to disable Oracle table NUMBER column type auto round-up

    Below is an example,
    SQL> create table a
    a_col1 NUMBER(8, 2)
    SQL> update a set a_col1=1.999 where ...
    I found column 'a_col1' of table 'a' value will be 2.00, but the application is for some financial calculation and doesn't allow any difference of the amount value (like, 1.999 <> 2.00), what I want to achieve is to disable the Oracle NUMBER type auto round-up and make above 'update' SQL fail with error, so I can trap the error and handle it in the program.
    Could anyone advise me how to achieve above or any good suggestion ? Thanks.

  • How to disable log4j via configuration file

    Howdy,
    I am using the quartz library which uses log4j, how can I disable log4j in my release version? where can I find a sample configuration file to disable log4j?
    TBH i am not sure if its actually running as i am not pointing it to config, i get these warnings:
    log4j:WARN No appenders could be found for logger (org.quartz.simpl.SimpleThreadPool).
    log4j:WARN Please initialize the log4j system properly.
    But I would prefer to just disable it all together (or initialize it correctly and make it do nothing)...so I am looking for how I can accomplish this. I've read over the docs here:
    http://logging.apache.org/log4j/1.2/manual.html
    They are a bit long winded for what I need to do so I might have missed it, but i am just looking for how to structure a minimal con fig file to properly initialize log4j and prevent it from logging anything

    tiburblium wrote:
    Now quick question, how can I modify this to prevent logging from occuring? It seems as if I set log4j.debug=FALSE nothing is logged, is that all thats required? set rootLogger to OFF if you intend to turn off logging, something like this.
    log4j.rootLogger=OFF, R
    Also how can i specify a null appender? I dont want log4j to attempt to log to a file on an end users systemlog file is not created on the end users system. It is created in the app server where the application is running. Setting rootLogger to OFF should take care of your problem as nothing will be logged.

    I suppose that you have Windows Vista installed. If thats right then go to Control Panel -> Hardware and Sound -> Recording -> choose either "FrontlineIn" or "Frontmic" (which is available in this moment) and dont forget to connect your headset before.

    Hello all,
