Change Hostname/IP's on installed GI11.2.0.3

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.

Change Hostname, IP after IDM install

What are the changes in settings etc that need to be made after hostname/IP address of Host has been changed, which already had a OAM/OID/OIM existing install?
The managed servers are failing to start - hostname of the Host has been changed at OS level.

You must change
1. StartManagedWebLogic.sh
2. Recreate certificates (If you wish to start/stop services using Console)
3. tnsnames.ora in OID ORACLE_INSTANCE
If you share at what stage managed server are failing then I can share what to change and where

Cluster changing hostname & Logical host

hello I have sunCluster 3.1 update 4.
the cluster is 2(v440) + 1(v240) installed on solaris8.
Did anyone actualy succeeded to change the hostnames of all the nodes & Logical host on SunCluster system like above?
I saw a procedure that is not realy supported :
1. Reboot cluster nodes into non-cluster node (reboot -- -x)
2. Change the hostname of the system (nodenames, hosts etc)
3. Change hostname on all nodes within the files under /erc/cluster/ccr
4. Regenerate the checksums for each file changed using ccradm -I /etc/cluster/ccr/FILENAME -0Reboot every cluster node into the cluster
is it works?
Thanks & Regards

So if I understand you correctly, you have two metasets already created and mounted. If so, this is a fairly tricky process (outlined from memory):
1. Backup your data
2. Shut down the RGs using scswitch -F -g <RGnames>, make the RGs unmanaged
3. Unmount the file systems
4. Deconstruct the metasets and mediators
5. Shutdown the cluster and boot -x
6. Change the hostnames in /etc/inet/hosts, etc
7. Change the CCR and re-checksum it
8. Reboot the cluster into cluster mode
9. Re-construct metasets and mediators with new host names
10. scswitch -Z -g <RGs>
If you recreate your metasets in the same way as they were originally created and the state replicas haven't changed in size, then the data should be intact.
Note - I have not tried this process in a long time. Remember also that changing the CCR as described previously is officially unsupported (partly because of the risks involved).

What needs to be changed if we change hostname in linux

Dear all,
I have a question and will appreciate for appropriate answer(s).
My machine name was lxcms120.cern.ch and Oracle 10g DB was running fine on it (listener, DB, Enterprise Manager). It is not a production system rather a test system.
Now, i changed its name to docms11.cern.ch
I change hostname in listener.ora & tnsnames.ora and listener started successfully.
I started db from sqlplus and it started without any complaints.
Now, when i tried to start Enterprise Manager (emctl start dbconsole), it didn't and return this error.
OC4J Configuration issue. /localscratch/orahome/oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_docms11.cern.ch_oralxcms120 not found.
Now, i know that when the machine name was initially lxcms120, it was /localscratch/orahome/oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_lxcms120.cern.ch_oralxcms120
and if i go to that directory, i could see OC4J_DBConsole_lxcms120.cern.ch_oralxcms120 but of course there is no OC4J_DBConsole_docms11.cern.ch_oralxcms120
My dbname instance is oralxcms120 and has nothing to do with hostname.
So, what is the solution to the problem. Moreover, are there any steps to do while changing hostname of the oracle database like in my case which i can follow to make all required changes.
Best regards,
Anjum

You will need to do a little more than just directory rename,
From Oracle document,When the database host name (including the domain name) or the IP address changes, deconfigure and then reconfigure the Database Console with the repository create command. Run the following command:
emca -deconfig dbcontrol db -repos drop
emca -config dbcontrol db -repos create
or
emca -deconfig dbcontrol db
emca -config dbcontrol db -repos recreate

How to repair Open Directory Master after Changing Hostname

Summary:
How to repair Open Directory after Changing your Server's Hostname (see separate post)
Problem:
I had to change our server's hostname from a private hostname (server.name.private) to a public hostname (name.dyndns.org).
Procedure:
1. Precautions:
Since I was anticipating major dramas I tested the change of hostname on a clone ( I used Super Duper, and I very strongly advise everybody to heed this warning because a change of hostname will corrupt your server services, in particular Open Directory)
Second, I exported the network users from Server Admin and copied the archive to the Drop Folder of the server's local account (because the network accounts will be unavailable after demoting the OD Master.)
2. Change hostname and demote OD Master
a) I re-booted the server from the clone
b) I changed the hostname in Server App and I noticed that the Open Directory Password and the Kerberos database were still stuck with the old hostname.
c) I then demoted to a standalone directory (Server Admin) and I tried to promote the server to an OD Master using the Server App (Manage Network Accounts). Server App always returned an error saying I should check my network settings.
3. List of 'fixes'
I tried the following fixes to no avail (which does not mean that you can skip them)
a) I checked the DNS entries, forward and reverse were working fine (sudo checkip -changehostname)
b) Checked with Lookup in Network Utility, all was fine
c) I deleted all system certificates (Keychain) which showed the name of the previous hostname
( N.B. you need not delete email certificate and private/public keys)
d) I tried to assign a new static IP in Networking Preferences (had no visible result)
e) I re-booted from the working drive and I re-paired permissions on the clone; I ran disk repairs.
Despite all this I could not re-create an OD Master.
I then looked for this dubious folder /var/root/Library/Application Support/Certificate Authority.
I could not find this folder when using the Finder's Go To Folder, nor did "Easy Find" see this folder.
I was about to give up when I read the posts on this page and I entered the Terminal commands
sudo rm -R /var/root/Library/Application\ Support/Certificate\ Authority/
I had not much hope when I set about to re-create the OD Master from the Server App.
But lo and behold !!! I did not trust my eyes when Server App claimed that the OD Master had been successfully created. And indeed, Server admin showed a running OD Master, LDAP, Kerberos and Password Server all running again !
Final touch: re-import the user accounts.
Epilogue:
I woud not have been able to fix this issue had not so many others shared their experience and the working solution.
(Refer : https://discussions.apple.com/thread/3219325?start=0&tstart=0 )
Thank you all !
Let's hope that Apple will fix this annoying issue in the next server update.

Twistan

Changing hostname on Callmanager 6.1 and generate new SSL

I'm looking to change the hostname of our Callmanager because of a change in the naming convention for all our servers.
Is it as easy as it seems or are there any precautions I need to be aware of?
My thoughts were to just Change hostname under Cisco Unified CM Configuration for both PUB and SUB
Since I use mostly IP address for most of my configuration, are there anything else I need to be concerned about?
Also, how do I generate a new SSL cert based on this change so admins and users won't get a certificate mismatch prompt?
Thanks!

Oracle 11.2 standalone grid infrastructure - change hostname

Hi
I have changed hostname of my server running RHEL 5.3 with Oracle 11.2 Grid Infrastructure (standalone). After I changed the hostname of the server, the crs daemon stopped working and I cannot connect to my +ASM instance any longer.
In Oracle 10g2it was enough to run localconfig delete, localconfig add
What should I do in 11.2 ?
Thanks for help
Groxy

Hi Groxy,
I recently found myself asking the same question and after a fair amount of digging around I found a way to do it. Your question is now a few months old, so maybe you have found the solution already, but if not the key is using roothas.pl rather than localconfig. I have written a brief blog post covering the approach I used, so please check that out if you want more information.

There is no way to change the language in Palm Desktop that I am aware of once it is installed.
You may need to remove the current Palm desktop and then download an english version of PD.

Why would you need to do this?
Generally, it is not possible (not supported). However, you can do that for certain modules (like HR/Payroll). Refer to the following note for more details:

How to disable auto-changing hostname?

I set my computer a hostname (let's say "MyComputer"), but when I connect to wired network, it changes hostname to whatever reverse DNS IP lookup turns out (let's say "Workstation312").
I know I can change the hostname using "hostname" in terminal- but is there a way to disable auto-changing hostname?
