Removing an inaccessible or destroyed node from Oracle RAC 11gR2

What do you do if you lose a node in a RAC as a result of destruction, theft, or other unrecoverable error? How do we clean up the existing cluster so the inaccessible node is removed permanently from Oracle Clusterware and Oracle RAC Databases?

I demonstrate the current process with 11gR2, which now has many new crsctl commands that can help with this administrative task.

Obviously when this type of thing does happen in production, I’m sure it’ll be impossible to remain calm and collected, but I hope this video helps to demonstrate just how easy it is to deal with this type of disaster.

Please enjoy!

    Hi Eric,

    First, very nice work on your new BLOG website.

    Second, I couldn’t ask more once I viewed your RAC installation viedos.
    They are exactly what is required to me at this point in work (I am a server solutions architect and team manager, less experience with RAC installations).

    Once request thought, you have mentioned in your video that you intend to publish a document which summarizes all the steps you demostrated. This would be very helpful as a reference for installing 11gR2 RAC. What are your intensions here?

    Keep up the good job and thanks again for your efforts.

    Shai.

    Yes, I will be documenting everything once I have a set of videos produced. I find documentation tends to inflate hits, but videos can really help to illustrate concepts and reduce the apprehension associated with just following a “how to” some other guy wrote.

    Plus there are a lot of how-tos on the net.

    That being said, I will be documenting after. Famous last words of every IT professional I think. =)
