Change of IP in RAC

Hi,
Thanx a lot for this discussion forms as i am getting the response very quickly.
What happens in RAC environment if i change my instances public IP /virtual IP.
Does it affects ????
If it doesn't what and where are the changes have to be made??
Thank you.

The following will have to be considered:
>
- You must ensure to your SAN storage vendor that the IP change will not affect the RAC servers. On my client's case, they moved from 192.xxx.xxx to 172.xxx.xxx segment. We consulted to the EMC engineer if there will be problems with the Navisphere detecting the new IP (172.xxx.xxx) of the RAC servers, luckily after the restart, the LUNs were still detected and the new IP was recognized
- Changing the Public and VIP will entail updating the Net Services for the new IPs
- Database links going to the RAC servers have to be modified to reflect the new IPs
- NFS mount points on RAC servers should be noted, edit the /etc/exports on the source servers to reflect the new IPs
- DNS entries on the 172.xxx.xxx have to be created
- DNS entries on the 192.xxx.xxx have to be deleted
- If you are using OCFS2, you to edit the /etc/ocfs2/cluster.conf to reflect the new IPs
- Also, you must be with your network engineer during the activity. If ever you encounter some route problems, he could easily solve it.

Changing GLOBAL_NAME in 11g RAC

Hi, All -
I am running a two node RAC 11g (11.1.0.7) database on RHEL5. I need to change the GLOBAL_NAME.
SQL> select * from global_name;
GLOBAL_NAME
dbname
SQL> ALTER DATABASE RENAME GLOBAL_NAME TO dbname.companyname.com
I just want to confirm that I only have to run this on one node and fix the db links.
Are there any other steps involved since it is a RAC environment?
Thanks in advance!

Infotype 77 changes to reflect new race and ethnicity categories

To incorporate the new race and ethnicity categories SAP note 435204 needs us to implement support pack SAPKE47063 (Release 470). However we are currently on SAP KE47060 Human Resources and NOT ready to apply SAPKE47063, is there any way we could implement the new race and ethnicity categories by applying some other oss notes.
Thanking you in advance.

Thank you for your feedback.
The new Federal Changes have come up with a new field called Ethnicity in addition to field call Ethnic Origin. The config allows us only to update the Ethnic Origin. In the OSS note 435204 they talk about updating this Federal requirement using the support pack SAPKE47063 but we are currently on SAP KE47060.
Thanks

PRIF-33 and CRS-02307 while changing public network interface, RAC

Hi,
I'm working on an Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production With the Partitioning, Real Application Clusters, Automatic Storage Management. It's a 3 nodes RAC: mgvdb01/02/03
After the installation I had to change IP (different IP and Subnet) to the RAC:
From 172.17.1.0/24 to 10.19.201.0/24.
Node from 172.17.1.31/32/33 to 10.19.201.31/32/33.
The same for VIP(s): from 172.17.1.131/132/133 to 10.19.201.131/132/133.
The oifcfg iflist shows correct ips configuration:
[oracle@mgvdb01 bin]$ ./oifcfg iflist -p -n
eth0 10.19.201.0 PRIVATE 255.255.255.0

I'm following doc 276434.1 from Metalink: How to Modify Public Network Information including VIP in Oracle Clusterware, starting from Case III "Changing public network interface, subnet or netmask".
But at the first operation I've a problem:

Change system time in RAC cluster

Hi,
We need to change the system time of two nodes involded in a RAC cluster, both the nodes are almost 15 minutes ahead of real time but are in sync with each other.
Does Oracle database require to bounce to get the latest changed time?
or does the whole cluster services needed to be stopped for 15 minutes after changing the time and then started? just in case not to confused with the transactions happened when the system was 15 minutes ahead.
The metalink note ID 368539.1 explains that PMON process does the service registration when the database was started. The PMON will not take the changed time dynamically?
We have oracle 10.2.0.2 database on HP UX 11.31
Please clear this confusion.
Thanks.

Your RAC Cluster would be using either of
a. NTP --- external to Oracle
b. Oracle Cluster Time Synchronization Service -- part of the Oracle Grid Infrastructure
It seems that you are not using NTP -- else the two nodes would have the same time as "the rest of the world".
You should see "Cluster Time Synchronization Service" in your clusterware logs.
Since you plan to reset the time backwards, I suggest that you shutdown and reset the time manually.
Remember that timestamps written to various log files and "last update" time of various files themselves, will duplicate or overlap with existing files.
Note : PMON service registration doesn't come into play here.

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.

Changing Sys password in RAC

We are into the process of changing sys password of our RAC database.
If i change password on one node, will that password be get reflected on another node ??
(Since sys password is also stored in password file, i doubt, if change password on one node, the password file on another node will also get updated).
we have separate password files for each instance e.g inst1, inst2
so do i have to give command
alter user sys identified by new password .....on inst1
and
use orapwd ustility on inst2 to change sys password.
or else
alter user sys identified by new password......on inst1
alter user sys identified by new password(same as that of inst1) .....on inst2

Change DB port in RAC

Hi,
This is the present configuration of Oracle EBS R12.
Applications: R12.1.1
DB : 11.2.0.3
DB Tier: 4 node RAC
Apps Tier: Windows
DB port : 1523
At the moment DB port is 1523. Local listeners are on 1523 and Remote listeners are on Scan port 1881.
Client wants us to change port from 15xx series to 1885. Client also wants us to change service name in tnsnames.ora and there should not be any "INSTANCE_NAME" in connection string of tnsnames.ora.
Please guide us how we can achive it. We are in doubt that if we manually do changes and run Autoconfig then it rollsback changes and put original settings.
Thanks.

Hi,
Please guide us how we can achive it. We are in doubt that if we manually do changes and run Autoconfig then it rollsback changes and put original settings.
Please try changing the listener configuration using NETCA and run autoconfig.

Change Data Capture on RAC

Hi ,
I have to install CDC on a Solaris RAC environment having 2 nodes.
I have installed on a single node database , can someone tell me if the procedure is same.
Regards
Kumar

Your first paragraph states that you have a 2 node RAC cluster.
Your second paragraph says you have a single node database.
This does not compute.
Please respond with your actual configuration and your exact version number to 4 decimal places if you need more help.
Synchronous or asynchronous? autolog or hotlog? Affects how CDC mines the data. Assuming you have chosen to mine the redo logs you have separate redo threads for each node.

Changing oracle_home(standalone to ORACLE RAC).

Customer has two oracle environments on the same envioronments.
1) Standalone database running on Standalone oracle_home.
2) RAC databases running on RAC ORACLE_HOME.
Now customer would like to change standalone database to RAC ORACLE_HOME. What is the procedure for this.
Oracle version is 11.2.0.3.4 on both environments. Just i need to change the oracle_home only. If any additional clarifications...happy to reply with more details....
Thanks in-advance.

Please use the below link, its helpful
http://docs.oracle.com/database/121/RACAD/cvt2rac.htm
Single-Instance Database on a Cluster Running from an Oracle RAC-Disabled Home
You can create a single-instance database on a cluster running from an Oracle home with the Oracle RAC option disabled. To create an Oracle home on a cluster with Oracle RAC disabled, you can select local and non-cluster on the Node Selection Page of Oracle Universal Installer when installing the Oracle Database software. You can also performed a one-node cluster (with Oracle RAC) installation, but later disable the Oracle RAC option.
Perform the following procedures to convert this type of single-instance database to an Oracle RAC or Oracle RAC One Node database:
1.    Use DBCA to create a preconfigured image of your single-instance database as described in "Use DBCA to Create an Image of the Single-Instance Database" To perform the conversion manually, shut down the single-instance database.
2.    Change the directory to the lib subdirectory in the rdbms directory under the Oracle home.
3.    Relink the oracle binary by running the following commands:
4. make -f ins_rdbms.mk rac_on
5. make -f ins_rdbms.mk ioracle

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)
