Changing ip addresses of rac hosts.

I have a 2 node oracle cluster running 10.2.0.3 on linux itanium and we need to move the 2 servers to a new network.
Can anyone point me to a good doc the detail the steps involved with changing the ip addresses for the rac private interconnect?
Not sure in which order do I change the ipaddress configurations I assume the clusterware needs to be disabled while this is reconfigured?
Any help is greatly appreciated.
Thx.

How to change IP address of a host ?

I know that we could know the IP address of a host by using the getLocalHost class but can we change the IP address to out desired IP address. Is there any API for this.......

There's no API for that. And usually your IP address is assigned by your network administrator or by some server in your network that knows what it's doing.

How to Change IP Address?

Hi,
I've a two node RAC working fine. I want to do an experiment and want to chang the VIP and private IP adresses. I canged the IP addresses in /etc/hosts files on bothe nodes and re-configured the eth1 with new IP addresses. I rebooted the nodes. When I try to start crs, I get error:
CRS-0184: Cannot communicate with the CRS daemon.
My question is that is it possible to change IP address of RAC nodes? If yes then what are the steps?
Thanks.

If you change your VIP to a different subnet, then you have to change your Public IP to the same subnet as well (vice versa)..
You may not have to change your Private IPs (let's say 10.10.10.x) because these are your interconnect addresses and are "private" to the RAC nodes...

Need to change IP address and host name on a ORACLE 10g RAC setup.

Hi Forum,
I have a task to change the IP address, host name and host related details for the ORACLE 10g RAC 2 node setup. So Can anyone tell me the procedure to do the same on both the nodes.

change IP Address Public + VIP + Interconnect

change VIP name

If you'd like to change HOSTNAME... Metalink (NOTE:220970.1)
Can I change the public hostname in my Oracle Database 10g Cluster using Oracle Clusterware?
Hostname changes are not supported in Oracle Clusterware (CRS), unless you want to perform a deletenode followed by a new addnode operation.
The hostname is used to store among other things the flag files and Oracle Clusterware stack will not start if hostname is changed.
Changing the Private Interconnect
o Change of the IP Address: change the IP address in the hosts file and/or DNS and make sure that ASM and the database also use the same interconnect
o Change of the private node name used by Oracle Clusterware: requires a reinstall of Oracle Clusterware
So, Public or Private hostnames can only be changed by removing/adding nodes, or reinstalling Oracle Clusterware. VIP Hostnames can be changed
But you can read this idea (reinstall CRS)

Message Server Unreachable (after changing IP address at host)

Hi guys,
I changed the IP address in my server. According to note 403708, I updated the new IP address in /etc/hosts. The note also suggests me to change in /etc/services but I see no IP address for me to update.
Later when I restart my sapinstance, I see the disp+work.exe is "Running, but Message Server Unreachable". I've also updated the IP address in SM59 but I see no change.
This is what I got from dev_rfc.trc:
ERROR file opened at 20071206 221839, SAP-REL 620,0,674 RFC-VER 3 549374 MT-SL
T:5048 Error RFCIO_ERROR_MESSAGE in abrfcio.c : 1400
T:5048 <* RfcDispatch [1] : returns 1:RFC_FAILURE
This is what I got from dev_disp:
WARNING => DpNetCheck: NiAddrToHost(1.0.0.0) took 5 seconds
***LOG GZZ=> 1 possible network problems detected - check tracefile and adjust the DNS settings [dpxxtool2.c 3212]
Anyone has any idea?

Yes I'm on Windows, the path that i'm refering is:
winnt/system32/drivers/etc/services
winnt/system32/drivers/etc/hosts
Anyway my prob is fixed now. Probably the problem is due to I did not restart the server after changing the IP. Anyway everything looks pretty fine now
Thanks guys

Want to change Public, private and vip address on RAC 10g R2 windows 2003

The network section told us the configuration of the network who support our cluster will have to change all ip address.
We are looking for a complet document who give all the step by step instructions how to make this change.
We have to change the Public, private and VIP at the same time of our 3 nodes cluster.
We know the OCRCFG will be impact. So we will take backup of it first.
Can someone are able to indicate us how to procede to execute this task.
Thanks

Hi,
i check the Note:283684.1 you give me, but it didn't give all the answers to my problem.
I finally found a recipe to make the job. I would like to tell you it's not supported be Oracle, but it work very well
Don't forget to take a good backup of the ocrcfg and vote disk before you start.
Here we go:
Stop all Oracle service on all nodes before the change of the address, the low format of the ocrcfg and vote disk
change the address in the file host in C:\WINDOWS\system32\drivers\etc with the new address
change the ip address in the window network definition connection with the new address
ocopy \\.\ocrcfg d:\backup\ocrcfg.dmp
ocopy \\.\votedsk1 d:\backup\votedsk1.dmp
rem go to directory of the cluster binary crs\bin
cd /D D:\Oracle\Ora10g\crs/bin
rem Format raw ocrcfg and vote disk
LogPartFormat.exe \\.\ocrcfg /q
LogPartFormat.exe \\.\votedsk1 /q
rem Run in prompt mode the cluster setup
rem crssetup.exe config -nn %s_nodenumberlist% -pn %s_privatenamelist% -ch %ORA_CRS_HOME% -oh %s_OracleHome% -c %s_clustername% -l "%s_languageid%" -q %s_votedisklist% -g %s_usergroup%
rem example for 2 node
crssetup.exe config -nn host_name_node_1 ,1,host_name_node_2,2 -pn host_name_node_1-priv,1,host_name_node_2-priv,2 -ch D:\Oracle\Ora10g\crs -oh D:\Oracle\Ora10g\crs -c crs_lab -l "CANADIAN FRENCH_CANADA.WE8MSWIN1252"; -q "\\.\votedsk1"
rem ensures that all nodes are configured with the same port for the ONS
racgons.exe add_config host_name_node_1:6200 host_name_node_2:6200
rem oifcfg to direct components to use specific network interfaces
oifcfg.exe setif -global "Public"/10.200.5.0:public "Prive"/192.169.255.0:cluster_interconnect
rem to rebuild the vip address vipca in wondow componant and make the incription in the cluster (in prompt mode or online)
rem at the same time it will create the gsd and ons service
vipca.bat -silent -nodelist "host_name_node_1,host_name_node_2" -nodevips "host_name_node_1/host_name_node_1-vip/255.255.255.0/Public,host_name_node_2/host_name_node_2-vip/255.255.255.0/Public";
rem vipca
rem check the state of the crs services (inscription)
crs_stat -t
rem now make the registration of the listener in the cluster.
rem important don't use the prompt command below, it will give you a crs-0223 error at the startup service
Rem to solve this problem use netca on line
rem crs_register ora.host_name_node_1.LISTENER_host_name_node_1.lsnr -dir D:\Oracle\Ora10g\crs\crs\profile
rem crs_register ora.host_name_node_2.LISTENER_host_name_node_2.lsnr -dir D:\Oracle\Ora10g\crs\crs\profile
rem srvctl start nodeapps -n host_name_node_1
ren srvctl start nodeapps -n host_name_node_2
netca
rem check the state of the crs services (inscription)
crs_stat -t
rem start oracle object service and cluster volume before registering and accessing to asm services
sc \\host_name_node_1 start ”Oracle Object Service”
sc \\host_name_node_1 start OracleClusterVolumeService
sc \\host_name_node_2 start ”Oracle Object Service”
sc \\host_name_node_2 start OracleClusterVolumeService
rem go the the rdbms directory to make the registration of asm and the database
set ORACLE_HOME=D:\Oracle\Ora10g\rdbms
rem add the service asm in the cluster in my case asm1 and asm2 for my 2 nodes
srvctl add asm -n host_name_node_1 -i +ASM1 -o %ORACLE_HOME%
srvctl add asm -n host_name_node_2 -i +ASM2 -o %ORACLE_HOME%
rem start the asm service on each node
srvctl start asm -n host_name_node_1
srvctl start asm -n host_name_node_2
rem check the state of the crs services (inscription)
crs_stat -t
rem go to the bin directory of rdbms directory to make the registration of the database
cd /D D:\Logiciels\Oracle\Ora10g\rdbms/bin
rem register the database (in my case labotary lab) and the to database service (lab1 and lab2) of each node
srvctl add database -d lab -o %ORACLE_HOME%
srvctl add instance -d lab -i lab1 -n host_name_node_1
srvctl add instance -d lab -i lab2 -n host_name_node_2
rem finally start the database
srvctl start database -d lab
rem go to directory of the cluster binary crs\bin
rem all the services
cd /D D:\Logiciels\Oracle\Ora10g\crs/bin
rem you can go in the database with sqlplus and check all your components
crs_stat -t
I hope this will help someone who are in the same situation

Changed IP address, how do I update the clients

I've poked around but all I can find is info about how to change the IP address of a TC without additional information about what to do with existing clients.
I'm not using a TC in this case (NAS frontended by a Mini providing AFP accesss), but I figured this would be the best place to ask.
I set up TimeMachine on most of our Macs (all 10.7 and 10.8) a few weeks ago, but just had to reconfigure my network which neccesitated changing the IP address of the host that provides the TM remote disks.
How do I tell the clients to start using the new address of the server? Will just adding a new disk do the right thing (I haven't tried as I don't want it to clobber what already exists).
Thanks.

Yes, you have to change the setup in each computer to redirect it to the new location of the backup disk..
You can do a TM reset.. but that should not actually be necessary.
See A4 here. http://pondini.org/TM/Troubleshooting.html
But TM is smart enough that when it finds the disk.. it will then find its previous backups and continue the backup .. after suitable verification. You can change the computer name. Change the disk name. Change the backup sparsebundle name.. TM will still find it and continue to use it. And even if there are multiple sparsebundles or disks with the same name or even computers with the same name.. which would break network rules,, but TM still won't get confused.
Again read up a bit of how TM works its magic.
http://pondini.org/TM/Works.html
The UUID is picked up from source hard disk I guess.. and that is what is used. This ensures everything is kept separate from names or even IP address.

Please send my password belong to [email address removed by host]

I change my password but wat is the new password belongs to [email address removed by host]

That's not how it works. This is a public forum, not Adobe customer service or a lost password facility. Nobody can tell you passwords not even Adobe staff.

Do i need to reconfigure OEM Database Control when change ip address?

Hi all.
Do i need to reconfigure OEM Database Control after a change of ip address?
I mean, i have an OEL5 box with 10g Rel2. I have configure the server with a static ip address.
This server will be sent to another location and it's possible the ip address will be changed. It will remain a static ip, but may change. Since i plan to deliver this server with rman jobs within OEM Database Control. I'd like to know if this will continue working after an eventual ip address change ....
Regards....!

Regards....!It depends.
When you created the dbcontrol, the configuration was put in a directory in ORACLE_HOME named something like 'hostname_sid' and there are also files under that where the hostname is baked into either the file name or a property of a configration defined within a file. If it is truly hostname, you might be ok, but if it is actually IP address instead of host name (I have seen that) then you obviously have a problem.
Over the years (and across several versions) I've found the OEM repository to be rather "brittle", and Oracle to have a rather cavalier attitude about rebuilding it. As a result, I specifically DO NOT have anything important - and very specifically my backup jobs - in the repository. I still schedule my backups through rman, though I know many people use dbms_scheduler. But even that appears to not be the same as an oem controlled schedule.

How to change IP address and hostname in solaris 9

Hi experts,
I want to change IP address and hostname of the server , Plese give steps, or any precise document .

did you already change your ip and host?
if not, do the following instructions:
* verify your hostname
- uname -a
- cat /etc/nodename
both should show your hostname
* alter your hostname
- uname -S newname
* verify the hostname
- uname -a
- cat /etc/nodename
both should show your newname
* edit /etc/hostname.ce0 (type ce0 depends on your net device)
- echo 'newname' > /etc/hostname.ce0
* verify /etc/hostname.ce0
- cat /etc/hostname.ce0
should show your newname
* edit the following files
- /etc/net/ticlts/hosts
- /etc/net/ticots/hosts
- /etc/net/ticotsord/hosts
replace old with new hostname
* edit /etc/inet/hosts
replace ip and hostname
* you have to look for
- /etc/inet/networks
- /etc/inet/netmask
fit yout data
After doing all changes you have to reboot your system.
Use ipconfig to verify network data

Failed to get IP address for Local Host (2) , OPMNCTL: opmn start failed

HI,
Hi, I have installed on Oracle 10g on Redhat Enterprise Linux V.2.1 . I was able to start OEM without any issues. Recently I had changed the static IP address and I couldn't able to start OPMNCTL and getting the following error while starting opmnctl start. error message is as follows.
Failed to get IP address for local host(2).....
Failed to get IP address for local host(2).....
Failed to get IP address for local host(2).....
my current configuration in /etc/hosts file is as follows.
127.0.0.1 localhost.localdomain servername
After going through some of threads available in Oracle, I have added the static IP address in the /etc/hosts but still I am getting the same error.
my new hosts file is as follows.
127.0.0.1 localhost.localdomain servername
10.21.253.102 localhost.localdomain servername
I don't know why this is looking for localhost (2). I did not set up any local host (2) and I could not see anything in my network confiuration also.
could you please help me in this issue? I appreciate your help in this regard.
Thanks
venkat

Hi, i think that the application server part is looking for a /etc/hosts entry
in this format:
127.0.0.1 localhost
As i noticed, this is used for internal communication.
Try this entry as is, without a domain...

JMS transport - weblogic changes soap:address location="jms:.. to http

Hi,
Please help me to configure web service to use only jms transport.
I try to create web service that uses JMS transport.
I started from WSDL where I placed two elements:
<soap:binding style="document"
transport="http://www.openuri.org/2002/04/soap/jms" />
and
<soap:address location="jms://host:7041/contextPathName/serviceUriName?URI=queueName" />
Then in web service implementation I placed following annotation:
@WLJmsTransport(contextPath = "contextPathName", serviceUri = "serviceUriName", portName = "portName", queue = "queueName", connectionFactory = "connectionFactoryName")
Deployment is successful but when I look at generated WSDL (Admin console) I see that weblogic has changed <soap:address location="jms:.. to <soap:address location="http....
And when I look at monitoring I see that port is using JMS transport.
When I try to test my service using Admin console Test client I see that the queue is not used (Admin console/monitoring/Messages total is still 0) and service uses (I suppose) http transport.

Hi,
Please change "http://www.openuri.org/2002/04/soap/jms" to http://www.openuri.org/2002/04/soap/jms/ for soap1.1 or http://www.openuri.org/2002/04/soap12/jms/ for soap1.2.
There must be some mismatch between edoc and implementation.

Impact of changing IP addresses

Hi Experts, our company plans to assign new IP addresses to our Orchestrator servers. Are there any changes required to ensure this goes smoothly, or will there be no impact following the re-IP? Servers in scope include SCO Management
server, SCO Runbook server, SCO web service server, SCO SQL Server (hosting Orchestrator db).
Thanks!

Hi,
the IP Addresses can be changed. Orchestrator uses the Host names and FQDN you specified during setup. So if you didn't specified and configured anything with IP addresses durin Orchestrator setup or later it will work.
You can check in Deployment Manager how the Database is specified if not sure ...
If you use Firewalls remember to chnange the settings there ...
