    I also have some questions regarding RAC concepts:

    1) As per my understanding, ocrconfig commands only updates the ocr.loc file on all the available nodes. Does it updates anywhere else also ?

    2) As per my understanding, while clusterware is running, if we lost all OCR, then crsd.bin would be stopped and it won’t be restart automatically again due to unavailability of OCR. In this case we won’t be able to use commands like srvctl, crsctl, and ocrconfig which interact with OCR using crsd.bin process.

    But how will it affect other resources like database instance, listeners, scan, vips ? These all are still keep on running after losing all OCR and stopping the crsd.bin.

    Does all the nodes are still a part of the cluster or they behave as individually ?

    Thanks in advance.

    Pankaj,

    1. I don’t think it is writing anywhere else..

    2. The listeners scans vips are part of nodeapps and managed separately. Cannot comment about the nodes status , you have to check the alert log file to know this.
