Hi,

Is it possible to change the Hostname/IP's nodes on installed GI11.2.0.3?
Exist some notes for do this action on "GI standalone" but no for GI.


Regards,
David.

    Hi David,

    Check this document.
    How to Modify Public Network Information including VIP in Oracle Clusterware [ID 276434.1]

    In that Document..

    Changing public hostname
    Public hostname is recorded in OCR, it is entered during installation phase. It can not be modified after the installation. >The only way to modify public hostname is by deleting the node, then add the node back with a new hostname, or >reinstall the clusterwar
    Changing public IP only without changing interface, subnet or netmask
    If the change is only public IP address and the new ones are still in the same subnet, nothing needs to be done on >clusterware layer, all changes need to be done at OS layer to reflect the change.

    1. Shutdown Oracle Clusterware stack
    2. Modify the IP address at network layer, DNS and /etc/hosts file to reflect the change
    3. Restart Oracle Clusterware stack

    Above change can be done in rolling fashion, eg: one node at a time.

    Tks very much for the answers. Very interesting all of them!

    I will try the "Shivananda Rao" solution because is for a test environment.

    Hi,

    I found this note:

    How to Clone an 11.2.0.3 Grid Infrastructure Home and Clusterware [ID 1413846.1]

    Can I use this note for clone the GI in other environment with new hostname, doesn't it?

    Regards,
    David.
