RAC server IP change

Dear All,
OS : Suse Linux and SunOS
Database : 10.2.0.3.0
As per our company policy we need to change the IPs of all the servers , we are having 2 RAC servers ( 2 nodes each). My question is if the physical and logical ip of the RAC servers changed then what will be the impact on the RAC configuration.
Thanks,
Vipin

Hi,
You may use below two Oracle Metalink notes to change public or interconnect IP and VIP.
How to Change Interconnect/Public Interface IP or Subnet in Oracle Clusterware [ID 283684.1]
Modifying the VIP or VIP Hostname of a 10g or 11g Oracle Clusterware Node [ID 276434.1]
You also need to update tnsnames.ora files on your client side with new IP addresses.

Database startup after reboot of RAC server

Hello,
My config : 2 nodes w2k3 with 15 dbs . Oracle 10.2.0.3
I started to scheduled my rac server reboot so i follow the oracle doc to shutdown properly all db,asm,service,listener,etc...
Today one the server reboot, but some instance doesn't start (only five , and the last five in alphabetic order)
In the log :
db log : nothing just the shutdown
crs_log : the start of the 10 db but nothing for the last five !!
just a trace on one listener service :
StartResource error for ora.sqyora01.LISTENER_1522_SQYORA01.lsnr error code = 1

IMO : (i am not a great oracle dba, because i have not enough time to spend with, and my collegue need really simple think to do, like startup/shutdown a database, no more investigation)Why startup/shutdown a database? I have databases that work 24x7 and uptimes of over a year. The record so far, has been over 24 months uptime (1st downtime were caused by a powerfailure to the rack cabinet). And for a database instance that runs a number of processes and deals with 100's to 1000's of inserts per second.
it's easier to view that an oracle process take more cpu and so investigate in that database what's appens. Rather than search in my v$sql table to find witch schema doing wrong thinksNot sure what you are trying to say here. Single or multiple database instances do not change how a session looks like, or how SQLs are executed.. and thus not how you troubleshoot problems. Nor does it change resource requirements, or how you address these. But multiple instances do impact resource availability and requires one to split resources amongst instances - the end result of this is less flexibility.
It's easier to affect cpu ressource to a process, rather than configuring it in oraclePlease explain.
It's easier to stop a database rather than "put offline a schema"This is a "silly" statement to make IMO. Why do you want to offline a schema? Availability of applications and data are a critical feature in today's information system landscape. So why argue the complete opposite and say it is now more complex to make something less available?
By the same token, why do you want to offline a database? A down database is even less useful than a downed server - at least you can use the downed server as a doorstop.. ;-)
And if a database crash it only affect one application.Yeah.. and these happens when? Every few minutes? Every hour? Once a day?
This is not a valid argument. Oracle instances very seldom crashes just for the heck of it. Most often it is due to incorrect o/s configuration, problematic hardware, uncertified components, old drivers, etc. Or plain old application abuse of Oracle.
There is the theorical approach and practical one : I'm not alone is that case :
http://oracledoug.com/serendipity/index.php?/archives/1339-The-Reality-Gap-3-A-Single-Instance-per-Server.html
http://www.dba-oracle.com/art_dbazine_server_consolidation.htm
I have never done RDBMS as a theoretical thing. The most dynamic table (ito SQLs against it) I have, grows by more than 450 million rows per day. This is as real world as real world gets. And that is what shapes my experience and opinion. And Burleson and I have never seen eye to eye on a number of subjects - so quoting his views on consolidation does little to persuade me to change my opinion.
have you any ideas where can i found an error message that explain why my database doesn't start ? (like not enough ressource ;-) )Troubleshooting a problem starts with a very basic principle - isolation. Isolate the layer or moving part where the problem occurs. As the other instances are running, it means that the CRS software layer is up and running, that the storage layer is up and running and so on. So the problem should be with the instance that for some reason refuses to start? Confirm this by using sqlplus to start a down instance and looking at what its alert log file says. It should have some kind of pointer to what dependency that has not been met.

Restore from cold backup (rac server)

Hi All,
Oracle version : 10g
OS : SunOS dixie1 5.10 Generic_118855-36 i86pc i386 i86pc
I am having cold backup of RAC server (2 nodes), I want to restore from cold backup.
The problem is that : when i performed the cold backup using rman at that time Oracle was having 3 ASM diskgroups.But unforunately that disk is no more in use due to some fault.
Now my question is how can i restore from the cold backup as when i'll restore from the cold backup this will ask for the same ASM diskgroups.Even more if i creates the same diskgroup with the same name and same configuration then my doubt is that rman will allow me to restore the same from the cold backup as ASM disk header changed now ?
Thanks,
Vipin

Yes.You can do these and restore/recover your database.First you need startup your ASM instance then create your ASM disk groups and do following:
1.Edit pfile and change controlfile location to diskgroup(Consder that +dgr1)
2.Restore controlfile to this disk group using backup of controlfiles(you say that is cold backup)
rman target /
/*Instance need starting up from pfile*/
startup nomount ;
/*then restore controlfile,give full path of controlfile from coldbackup*/
restore controlfile from 'coldbackup_location\coltrolfile';
alter database mount;
catalog start with 'coldbackup_location';
backup as copy database format '+dgr1';
switch database to copy;
alter database open;

Server name changed

Exchange 2013, Outlook 2013
we're now moving from 2010 to 2013 Exchange. first thing i noticed, in the server settings of Outlook, the server name changed to some hex
[email protected] where before i used to have "mail.acme.com" there.
is this normal? instead of "mail.acme.com" we now get
[email protected]?

Hello Reno,
I have the same feeling but this change will decrease the hot issue “Your administrator has made a change to your mailbox” in Outlook.

New app version detected after server ip changes (server using DNS / dynamic ip)

I have a JWS app deployed. The codebase URL is using a name for the server (dynamic IP address), and when you start the app it detects a new version every time there's a server IP change (I have no way to get a static IP for it). As long as it's the same app, how can i prevent this to happen?
I need changes to be checked every time the app is launched at the client side, but this behaviour is a problem for me because I have a limited upload bandwitch available at the server side.

Ok, it seems to have been a problem for some time. I found this thread:

Essbase cannot start up after the DB server IP changed.

Hi,
My essbase is installed in server A and the DB server is in server B. For some reasons, the IP of DB Server (B) changed.
Then the essbase cannot startup. When run the StartUpEssbase.sh, no error shows up.
+[oracle@eucbi03 ~]$ ./StartUpEssbase.sh+
Starting all
Apache Ant version 1.7.0 compiled on December 13 2006
Buildfile: /home/oracle/app/epm/EPMSystem11R1/common/config/11.1.2.0/resources/instance/start.xml
Finish all
Environment:
Cent OS 6
Essbase 11
Any advise will be appreciated. Thanks.
Regards,
Alex

Hi John,
We didn't use the name for DB configuration. We used the IP. So I changed the 2 files.
And very thanks for your information, I resolved the problem by the document you provided. Just as you said, it's no need to update the files.
Here briefs the case and the solution:
Problem:
I used IP to config the DB server when setup the Essbase. But later, the IP of the DB server changed, the Essbase won't startup, either the administration services.
Solution:
1. Run the config tool (EPM_ORACLE_HOME/common/config/version_numberconfigtool.sh) and change the DB server setting (fill the new IP for the db server, and choose 'reuse the database' when prompted)
After this step, the essbase could startup. But administration services couldn't
2. Go to weblogic admin console (http://ip:7001/console). Edit the JDBC data source setting from old DB server to new one
After this step, the administration services could startup now.

SBS2011 Exchange Migration (Server configuration change is temporarily preventing access)

Greetings,
I 've begun an exchange migration from SBS2011 (Exch 2010) to 2013 Exchange. I am on this step of the deployment assistant, for reference, http://technet.microsoft.com/en-us/exdeploy2013/Checklist?state=2419-W-EQBEAgAAQAAAAQEAAQAAAAg~
I can login and access any users mailbox with the respective credentials if their mailbox is on the SBS exchange server.
Ive migrated a couple test users, and while I can access their owa box if I browse to the localhost of the 2013 server, I cannot access their mailbox internally nor externally if I go to the external FQDN of the owa site. All other users with mailboxes
still on the 2010 exchange work.
I get this message for those with mailboxes on the new server: A server configuration change is temporarily preventing access to your account. Please close all Web browser windows and try again in a few minutes. If the problem continues, contact your helpdesk.
Any ideas?
Thanks!

Hi,
On current situation, please check if you move mailboxes to the new Database properly. Please refer to Olaf’s

Portal server has changed DNS zone, CM URLs not

Hello,
we have a standalone server which changed from the DMZ to internal LAN. With this change the portal got a new DNS suffix and a new IP address. Now the portal is accessable but the acess URLs for CM repository objects having still the old DNS suffix in the URLs.
Has someone experience with changing DNS suffix of a portal server? What must be changed for CM? (using EP 6.0 with KMC, SPS12)
Thanks and regards
Alex

Hello,
found the solution: Systemadministration -> Systemkonfiguration -> KM -> CM -> Global Services (advanced mode!)-> URL Generator Service
Here I could change the Host entry to the new domain for all access paths of KM.

Ramifications of Server name change

What are the ramifications of changing the name of a Windows 2000 server on the operation of an Oracle database. I did this and the TNS listener failed to start. After changing the name back it works fine. Are there any suggested procedures for what files, etc. need to reflect the server name change for Oracle to work or do I need to uninstall Oracle, change the server name and then reinstall Oracle.
Thanks!

Hi,
some things to check are:
tnsnames.ora and listener.ora files (hostname...)
also, make sure that you change your DNS so that people can find the server under the new name.
Good Luck

Clone a RAC database to a new RAC server

Hi,
How can clone a RAC database to a new RAC environment ?
I installed Cluster and RDBMS 10g R1 in a new RAC server and I need to copy my database "dbrest" to the new server, my new database must have the same name ("dbrest"). My actual dbrest database is in ASM and I need to use ASM for the new database too.
I don't have any database in the new RAC environment.
At the end I need to have this configuration:
Source configuration:
SERVER:
Node 1: srvprod1
Node 2: srvprod2
CLUSTER DB: dbrest using ASM
Node 1: dbrest1
Node 2: dbrest2
Clone configuration:
SERVER:
Node 1: dupenv1
Node 2: dupenv2
CLUSTER DB: dbrest using ASM
Node 1: dbrest1
Node 2: dbrest2
How can I do this?
How can I copy my dbrest database to

use rman Duplicate Database on srvprod* to dupenv*
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14191/rcmdupdb.htm#BRADV165
When duplicate database can run on both dupenv1 and dupenv2.
use "srvctl" to add database, instance and services (if you have)
Usage: srvctl add database -d <name> -o <oracle_home> [-m <domain_name>] [-p <spfile>] [-A <name|ip>/netmask] [-r {PRIMARY | PHYSICAL_STANDBY | LOGICAL_STANDBY}] [-s <start_options>] [-n <db_name>] [-y {AUTOMATIC | MANUAL}]

Oracle RAC server's IP and Subnetmask change

Oracle DB Version:10.2.0.3.0
OS version : RedHat linux 4
Number of Nodes: 2
We need to move our RAC db servers from Atlanta to NJ. This move requires IP and subnet mask change. How we can do this chanse in for nodeapps / CRS components?

I am doing a clean installation of RAC 10g rev.2, and during the installation I set the netmask for the VIP to 255.255.252.0, which is different from the pub netmask of 255.255.255.0.
I ran the following:
srvctl modify nodeapps -n rachost1 -A 192.168.180.88/255.255.255.0/pub
srvctl modify nodeapps -n rachost2 -A 192.168.180.89/255.255.255.0/pub
I then stopped the services.

Different instructions for disable arch log mode on 11Gr2 RAC server?

Hello all,
I've run into a problem where I've lost my tape drive...and have no sysadmins to help.
I don't want my RAC instances to run our of space and halt, so I'm planning to take them out of archive log mode, and just do exports daily till I can move them or get tape going again.
This is easy enough with a non-clustered instance, but I'm reading around and finding conflicting information for doing it on a RAC system.
In the Oracle® Real Application Clusters Administration and Deployment Guide
11g Release 2 (11.2)...it states in simple terms:
(http://download.oracle.com/docs/cd/E11882_01/rac.112/e16795/rman.htm#i474611)
"In order for redo log files to be archived, the Oracle RAC database must be in ARCHIVELOG mode. You can run the ALTER DATABASE SQL statement to change the archiving mode in Oracle RAC, because the database is mounted by the local instance but not open in any instances. You do not need to modify parameter settings to run this statement."
and thats about it.
I've been researching and found a couple of other non-oracle official guides to this, where they describe a much more involved process, that seems to follow this path:
1. sqlplus into one instance and change the cluster_database=false scope=spfile sid='specific_node_name';
2. Shut down all instances, srvctl stop database -d <instance_name>
3. Startup the instance you changed cluster_database on with sqlplus and startup mount;
4 On this instance you do ALTER DATABASE NOARCHIVELOG;
5. On same instance change the cluster parameter back: alter system set cluster_database=true scope=spfile sid='specific_node_name';
6. Shut down this single instance
7. Start all instances with srvctl start database -d <instance>
I've found references to this at:
http://oracle-dba-yi.blogspot.com/2010/12/enabledisable-archive-log-mode-in-11gr2.html
and
http://www.dba-oracle.com/bk_disable_archive_log_mode.htm
Among other sites. I'm curious why the Oracle documentation on this doesn't mention all these steps?
I'm guessing the longer version is the path I should take, but I wanted to ask here first if this is correct?
I'm on Oracle 11Gr2....hasn't been patched with latest patchset, running on RHEL5, and is a 5 node cluster.
Thank you in advance,
cayenne

There are couple things you need to consider

your company have 5 RAC nodes I assume this is mid-to-large company, question you might ask to yourself Is your company really desperately don't have any available disk space for you to backup to temporary location / server?
However if you still insist and persistent with your strategy then follow the links you have, that is how to disable archivelog in RAC
CheersThank you everyone for the comments.
This is a DEV environment...and they are planning to move this all to a new facility where we won't have the powerouttages and old defunct equipment.
Right now...I do not have drive space to put all of this. I've informed them of the risks of not having point in time recovery. I really don't see any other choice on this....I don't want to run noarchive either...but I've been without tape to move the logs off for days now..and even with low traffic, I'm afraid they will fill and I'll have databases halting.
I think at this point, and again, this is not production data....I'm going to have to go with daily exports and that will have to do me till I can get these servers 'moved' to a new facility soon.
Again, thank you for the comments!!!
