Oracle RAC IP Configuration

Hi all
How Oracle RAC IP configuration uses gateway.
Thanks in advance,
Sarathi

Hi Friend,
Thumb Rules :
1. All public NICs must have the same name on all nodes in the cluster
2. Similarly, all private NICs must also have the same names on all nodes
Use component verifications commands like 'nodereach' or 'nodecon' for this purpose. Type cluvfy comp -help on the command prompt. If the 'cluvfy comp nodecon' command is invoked without -i, cluvfy will attempt to discover all the available interfaces and the corresponding IP address & subnet. Then cluvfy will try to verify the node connectivity per subnet.
You can run this command in verbose mode to find out the mappings between the interfaces, IP addresses and subnets. You can check the connectivity among the nodes by specifying the interface name(s) through -i argument
Note : If you metalink support, there is a step by step document *RAC and Oracle Clusterware Best Practices and Starter Kit (Linux) [ID 811306.1]*

10G RAC Database Configuration Querry??

Hi All,
I have installed the 10GR3 Grid and deployed the Agent to a system which has 10GR2 RAC Database with CRS installed.
1) When i try to configure the cluster database, should we use the VIP TNS entries as the Connect string or the Physical Node TNS Address.
2) After i have configured it i do not see Listener shown for either monitoring nor i am able to add manually.
3) Will any CRS components be monitored through Grid? For Me i dont find any though the CRS HOME oratab entry is enabled.
Please share your ideas and experience.. on this..

Is RAC node configuration when disk array fails on one node .

Hi ,
We recently had all the filesystem of node 1 of RAC cluster , turned into read only mode. Upon further investigation it was revealed that it was due to disks array failure on node 1 . The database instance on node 2 is up and running fine . The OS team are rebuilding the node 1 from scratch and will restore oracle installable from the backup .
My question is once all files are restored :
Do we need to add the node to the RAC configuration ?
Do we need to do relink of oracle binary files ?
Can the node be brought up directly once all the oracle installables are restored properly or will the oRacle team require to perform addition steps to bring the node into RAC configuration .Thanks,
Sachin K

Hi ,
If the restore fails in some way . We will require to first remove and then add the nodes to the node 1 cluster right ? Kindly confirm on the below steps.
In case of such situation below are the steps we plan to follow:
version ; 10.2.0.5
Affected node :prd_node1
Affected instance :PRDB1
Surviving Node :prd_node2
Surviving instance: PRDB2
DB Listener on prd_node1:LISTENER_PRD01
ASM listener on prd_node1:LISTENER_PRDASM01
DB Listener on prd_node2:LISTENER_PRD02
ASM listener on prd_node2:LISTENER_PRDASM02
Login to the surviving node .In our case its prd_node2
Step 1 - Remove ONS information :
Execute as root the following command to find out the remote port number to be used
$cat $CRS_HOME/opmn/conf/ons.config
and remove the information pertaining the node to be deleted using
#$CRS_HOME/bin/racgons remove_config prd_node1:6200
Step 2 - Remove resources :
In this step, the resources that were defined on this node has to be removed. These resources include (a) Database (b) Instance (c) ASM. A list of this can
be acquired by running crs_stat -t command from any node
The srvctl remove listener command used below is only applicable in 10204 and higher releases including 11.1.0.6. The command will report an error if the
clusterware version is less than 10204. If clusterware version is less than 10204, use netca to remove the listener
srvctl remove listener -n prd_node1 -l LISTENER_PRD01
srvctl remove listener -n prd_node1 -l LISTENER_PRDASM01
srvctl remove instance -d PRDB -i PRDB1
srvctl remove asm -n prd_node1 -i +ASM1
Step 3 Execute rootdeletenode.sh :
From the node that you are not deleting execute as root the following command which will help find out the node number of the node that you want to delete
#$CRS_HOME/bin/olsnodes -n
this number can be passed to the rootdeletenode.sh command which is to be executed as root from any node which is going to remain in the cluster.
#$CRS_HOME/install/rootdeletenode.sh prd_node1,1
Step 5 Update the Inventory :
From the node which is going to remain in the cluster run the following command as owner of the CRS_HOME. The argument to be passed to the CLUSTER_NODES is a
comma seperated list of node names of the cluster which are going to remain in the cluster. This step needs to be performed from once per home (Clusterware,
ASM and RDBMS homes).
## Example of running runInstaller to update inventory in Clusterware home
$CRS_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ORA_CRS_HOME "CLUSTER_NODES=prd_node2" CRS=TRUE
## Optionally enclose the host names with {}
## Example of running runInstaller to update inventory in ASM home
$CRS_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ASM_HOME "CLUSTER_NODES=prd_node2"
## Optionally enclose the host names with {}
## Example of running runInstaller to update inventory in RDBMS home
$CRS_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=prd_node2"
## Optionally enclose the host names with {}
We need steps to add the node back into the cluster . Can anyone please help us on this ?
Thanks,
Sachin K

RAC setup- Configure hostname in ODI agent

I have my Master & Work repositories hosted on a Oracle RAC environment. I have a standalone ODI agent which might installed in the same physical server or in a different server.
In a RAC setup, there are multiple hostnames for the same database. How do I make the ODI agent aware that it should look into a 2nd server (when the 1st host is down) when trying to connect to the repository ? I want to know where this should be configured in the agent setup.
Does this get automatically taken care of once I include both the hostnames in the JDBC URL of the repositories ?

All depends on the JDBC you're using...
JDBC Thin work with the Oracle listener,
and JDBC OCI (which need an Oracle Client on the machine) works with a TNS description (here you can define several HOST).
I had have several issues with the Thin on our RAC so we've changed for an OCI one...

Brice

Doubt on RAC IP configurations

Dear Legends,
As I'm trying to install RAC in VMWARE with OEL 5.7 64 bit and 11gR2 by following the article "ORACLE-BASE - Oracle Database 11g Release 2 RAC On Linux Using VMware Server 2"
Our Public host name "verac1.host.net" and "verac2.host.net"
VM Settings is "BRIDGED"
#PUBLIC

192.168.0.11 verac2.host.net verac2-priv
#Virtual
192.168.1.182 verac1-vip.host.net verac1-vip
192.168.1.183 verac2-vip.host.net verac2-vip
May I know these are the right one am using or not?
While trying to nslookup public hostname it is working from both nodes, but
nslookup verac1-priv
nslookup verac2-priv
nslookup verac1-vip
nslookup verac2-vip
error as : ** server can't find verac1-priv: NXDOMAIN
Do I need to proceed ? Or I need to rectify it here.

Question on 11.2 RAC Networking Configuration

I have a random question regarding the network interface configuration for (specifically 11.2) an Oracle RAC requirement. Is there a requirement anywhere that states that all nodes in the cluster must have the same named interface on each distinct node serving the same purpose in order for all nodes of the cluster to communicate properly?
Here is an example of my question - My curiosity is, is this a requirement?
Node 1
eth1 - 10.0.0.1 (public)
eth1:1 10.0.0.25 (vip)
eth2: 192.168.1.25 (priv/interconnect)
Node 2
eth1 10.0.0.2 (public)
eth1:2 10.0.0.26 (vip)
eth5: 192.168.1.35 (priv/interconnect)
Note: eth2 is private on node 1, where eth5 is private on node 2.
Does node 2 have to follow the same pattern where eth1 is public, and eth2 is private, or for node 2, can eth5 be assigned to the private subnet and eth1 be assigned to the public subnet?
Odd question I know. Any means to clarify for me would be most helpful and appreciated.
Thanks,
CJ

Doc 11.2.0.2 says:
About Network Hardware Requirements
* Public interface names must be the same for all nodes. If the public interface on one node uses the network adapter eth0, then you must configure eth0 as the public interface on all nodes. Network interface names are case-sensitive.
* You should configure the same private interface names for all nodes as well. If eth1 is the private interface name for the first node, then eth1 should be the private interface name for your second node. Network interface names are case-sensitive.
http://download.oracle.com/docs/cd/E11882_01/rac.112/e17264/preparing.htm#TDPRC123
Network Hardware Requirements (Linux Installation)
If you install Oracle Clusterware using OUI, then the public interface names associated with the network adapters for each network must be the same on all nodes, and the private interface names associated with the network adaptors should be the same on all nodes. This restriction does not apply if you use cloning, either to create a new cluster, or to add nodes to an existing cluster.
For example: With a two-node cluster, you cannot configure network adapters on node1 with eth0 as the public interface, but on node2 have eth1 as the public interface. Public interface names must be the same, so you must configure eth0 as public on both nodes. You should configure the private interfaces on the same network adapters as well. If eth1 is the private interface for node1, then eth1 should be the private interface for node2.
http://download.oracle.com/docs/cd/E11882_01/install.112/e17212/prelinux.htm#CWLIN209
As the documentation says this restriction is valid when Install using the OUI, but have different interface name is supported if configured manually.
Anyway if you are installing using the OUI you have the option to rename the interface thus like Bjoern said.

Suggestions to add a 10gr2 RAC to a 9iR2 RAC configuration.

Hello,
I want to add a new 10gR2 instance (with clusterware and ASM) to a working production RAC 92 installation (2 nodes on RedHat 3).
The old RAC is configured with raw devices.
For the ASM we plan to use a new configured LUN.
Can you point me to a document with the required steps?
Obviously we would not want to stop the running instances or to reduce the downtime at a minimum.
Thanks.
K

Please be aware that the document posted http://www.oracle.com/technology/pub/notes/technote_singh_crs.html
has some extra steps
Basically you need to stop the gsd from 9i environment before starting the 10g installer. This should detect the existing 9i installation. The installer will use the srvm of 9i and upgrade it to 10g OCR as part of the install. It is to be noted that only the 9i srvm is upgraded to the 10g OCR. The Oracm voting disk will continue to use its voting disk while 10g will use different voting disk.
This way we do not have to add the information again
Thanks,

Database upgrade in a Dataguard Configuration - Help !

Hello Everyone,
I am upgrading our test Oracle 11G RAC/Dataguard Configuration from 11.1.0.6 to patchset 11.1.0.7 and have run into an issue when trying to apply the patchset to one of our standby databases.
I have upgraded our primary database to 11.1.0.7 with no problems, however when this was done the Dataguard Broker configuration was disabled and redo log apply to our standby databases (all physical) was stopped. I next attempted to upgrade one of our standby databases to 11.1.0.7, whilst DG Broker was disabled. The clusterware (all our databases are part of RAC clusters) and DB Software upgrades were OK, but I was unable to run DBUA successfully (or at all) as it wont run against the standby DB.
Looking at the process for applying upgrades with Physical Standby databases in place in the Dataguard Concepts manual, it seems as though the recommended process is that I should have upgraded the standby database(s) first rather than the primary database. The two Oracle Consultants that were on site when I upgraded the primary DB, did not seem to be aware of this !
What now is the easiest (and quickest) way of upgrading the standby db to 11.1.0.7 (preferably without reenabling the DG Broker Configuration). Is it possible to re-instanitate the standby DB from the primary DB?
Any advice would be much appreciated.
Thanks,
Shaun.

Hi!
Updating a standby DB must be so easy, but I suppose now you are in troubble because your primary DB is ...0.7 and standby are ...0.6, but in this situaction there isn't any problem. You only need to have same version at Oracle DBs (...0.7) and initiate the recovery process or start DataGuard Broker process (if you have all redo logs since the beggining of update process).
Chiao!

11gR2- webutil upload file to AS on two nodes RAC?

Hellow experts plz help with the following issue,
we are using 11gR2 forms on two node rac,webutil configured on both nodes. upload/download files to AS folder(UP_FILES) using our forms. node 2 is actually replica of node 1(forms,reports,UP_FILES). we are now facing a problem that the form which upload file to AS, only upload that to the node from where it is running say if it is running from node1 then it upload files to folder UP_FILES on that node( as the entry in webutil.cfg file) but we want that UP_FILES folder should be synced with each other on both nodes and a form running whether from node1 or node2 upload the file to both nodes at time.
How this will be accomplished?
--------webutil.cfg entry
transfer.appsrv.read.3=D:\UP_FILES
transfer.appsrv.write.3=D:\UP_FILES
-----FORM UPLOAD CODE
      IF :CONTROL.FILE_LOC IS NOT NULL THEN
        acyr3 := :CONTROL.TXTVOUCHERNO||'-'||acyr2 ;
       FILE_RESULT := WEBUTIL_FILE_TRANSFER.CLIENT_TO_AS_WITH_PROGRESS(CLIENTFILE=>:CONTROL.FILE_LOC,
       SERVERFILE =>'D:\UP_FILES\'||acyr3||'.PDF',
      PROGRESSTITLE=>'UPLOAD TO DATABASE IN PROGRESS',
      PROGRESSSUBTITLE=>'PLEASE WAIT' );
      END IF;
--FORM DOWNLOAD CODE
        FILE_RESULT := WEBUTIL_FILE_TRANSFER.AS_TO_CLIENT_WITH_PROGRESS
             CLIENTFILE=>'D:\UP_FILES\'||acyr3||'.PDF',
        SERVERFILE =>'D:\UP_FILES\'||acyr3||'.PDF',
      PROGRESSTITLE=>'DOWNLOAD FROM DATABASE IN PROGRESS',
      PROGRESSSUBTITLE=>'PLEASE WAIT'
             CLIENT_HOST('rundll32.exe url.dll,FileProtocolHandler D:\UP_FILES\'||acyr3||'.PDF');
             IF FILE_RESULT THEN
message('File downloaded successfully from the Application Server');
END IF;

Well, you're uploading the file to one node, so this is no surprise. What you can do is to store your file on a shared folder (which might be a bit tricky on windows) or synchronize a folder between your nodes. Unfortunately Forms can't access ASM directly (assuming you are using ASM), so you can't store your files directly in ASM where it would be accessible from both nodes.

Oracle 10g RAC/Grid rename hostname and re-ip server?

Here is the situation. We are installing Oracle 10g in a RAC/Grid configuration. Servers were installed and configured with static IP's and unique hostname's according to instructions. The problem is the servers are being shipped to another location and the on-site administrators will have to rename the hostname's and give all the servers new IP addresses.
The question:
Is it possible to rename the hostname's and re-ip all the servers without having to reinstall all the Oracle servers in the RAC/Grid? Does anybody have any information on what will need to successfully accomplish this?
Regards,
Ed Bragg

Hi Ed!
I never tried this but I believe that after changing the IP addresses and reconfiguring the virtual IP's it should work. What you have to do is to reconfigure the ssh stuff with the keys, etc.
