Oracle Single Node RAC - Oralce Clusterware Install

Hi
I want to install Oracle Clusterware to perform Active / Passive failiver for a 2 node cluster
I plan to use Oracle Single Node RAC for this and have Oracle Clusterware control the active passive failover.
However - I do not want to use ASM in any of my set-up.
We have a NetApp filer and are using NFS / NetApp technologies to control backups (Oracle snap manager).
Is this possible?
All the documents I have include reference to ASM
If I try and install Grid - I am also asked for ASM information.
I find ASM an un-necessary overhead given the storage we have and do want to use it,
Can anyone help?

Hi,
no you don't need ASM to have RAC One Node. OCR and Voting disk can be on NFS, simply use Shared Disk location during installation, and you won't get asked about ASM.
http://docs.oracle.com/cd/E11882_01/install.112/e22489/storage.htm#CDECEBGH
Especially http://docs.oracle.com/cd/E11882_01/install.112/e22489/storage.htm#CDEDAHGB
What you should use in conjunction with NFS however is dNFS.

Oracle single instance rac installation

hi,
do I need minimum of 2 servers in order to carry out 11.2 oracle single instance RAC installation ? or that its possible with one node? and then can add more nodes in future?
is there any article/documents on this?
thanks

http://download.oracle.com/docs/cd/E11882_01/rac.112/e10718/clonerac.htm#CHDGFHCA
"The cloning process assumes that you successfully installed an Oracle Clusterware home and an Oracle home with Oracle RAC on at least one node. In addition, all root scripts must have run successfully on the node from which you are extending your cluster database."
also
http://download.oracle.com/docs/cd/E11882_01/rac.112/e10717/intro.htm#BEIHEJGD
"Overview of Cloning and Extending Oracle Clusterware in Grid Environments
Cloning nodes is the preferred method of creating new clusters. The cloning process copies Oracle Clusterware software images to other nodes that have similar hardware and software. Use cloning to quickly create several clusters of the same configuration. Before using cloning, you must install an Oracle Clusterware home successfully on at least one node using the instructions in your platform-specific Oracle Clusterware installation guide.
For new installations, or if you must install on only one cluster, Oracle recommends that you use the automated and interactive installation methods, such as Oracle Universal Installer or the Provisioning Pack feature of Oracle Enterprise Manager. These methods perform installation checks to ensure a successful installation. To add or delete Oracle Clusterware from nodes in the cluster, use the addNode.sh and rootcrs.pl scripts."
it doesnt directly say its possible and I cant find full documentation on how to go about it ... but seem like its possible ?

9ir2 Single Node RAC + RH80

Hi all.
I'm triying to install a single node RAC based in the single node rac for linux document in the metalink.
The document was made based in a oracle 9iR1 database an RH71, I have followed the steps and i have a working kernel made by my own, the raw devices, and softdog hacked for being testing only. But the service does not go up.
I don't know if someone have made a single node rac instalation and can help me to choose the right pieces.
I don't have a RHAS2.1 but I do have a UnitedLinux 1.0 Server Patched.
I want to try the RAC tech but here (ecuador-sudamerica) is dificult to find firewire cards and disks so I´m working around a single node instalation.
Any help will be apreciate.
Fernando

Hi
Database version and GI versions are 11.2.0.2.2. And these are not multinode RAC configuration at any given time only single instance will be there for any given database. Some thing like ACTIVE and PASSIVE in hardware clusters such are VCS (Veritas Clusters).
I agree with you failover sinario in multi node (2 or more) RAC environments. In single node clustering only one instance will be there, like services in multinode, here whole instance will be re created on available nodes.

1) I have created single node standard database called mydb in /u01/app/oracle/product/10.2.0/db_1 home (hostname linux1)
2) installed crs and asm on linux1 and linux2 and shared storag on ASM(which external HD running ieee1294 cards and ports) . no database is created on linux1 or linux2
3) I want to convert mydb to RAC DATABASE called mydb1 instance on linux1 and mydb2 on linux2 machine respectively.
4) copied and modifed xml as you see above called ConvertTomydb.xml to $ORACLE_HOME/bin directory
5) when I run
$rconfig ConvertTomydb.xml from $ORACLE_HOME/bin directory , i get the following error

SOA with Oracle 2 node RAC cluster

Hi All,
Just a simple doubt, I have successfully installed and configured SOA suite 11.1.1.3 & BAM in one wls Domain 10.3.3 in a linux box and could access all the application like BAM console, BPEL console etc .... also could see all my data-sources deployed in the Data Sources with a single node database.
1. Now I have to RE-configure this whole SOA suite with RAC (2 node database cluster) what changes or configuration needed to implement SOA suite with RAC database?
2. Do I need to create a "Multi Data Source" to configure RAC with SOA suite..?
Thanks

Read docs and understood that there must be shared storage for oracle clusterware and oracle ASM for oracle RAC to work.
Please let me know the steps to create shared storage for oracle clusterware and oracle ASM (considering virtualbox OEL) and to configure public,private and virtual IPs.
I already have document to create 2node oracle RAC using virtualbox with two nodes on the same laptop.so please dont suggest that doc.

How migrate Oracle 2 node RAC to EBS R12

Hi
How to migrate normal oracle 2node rac to ebs r12.
Regards,
Subba.

Happy to help you ... well I would be if I had any idea what you are asking.
A two node RAC cluster is two physical servers, and a storage array, running a single Oracle database of unknown version number: No application and no application server.
EBS R12, I presume, is a totally different product named E-Business Suite version 12.x
They have different architectures, different licensing, different, resource requirements, and totally different management requirements.
So I see two possible answers to your inquiry.
1. You far more clearly explain what you are asking.
2. You burn the two-node RAC cluster to the ground and install the product you want. That said would recommend not putting the application components of EBS on the two node cluster so you will need at least one additional server.

How to clone a 11.1.0.7 oracle single node db with asm instance

We need to clone a 11.1.0.7 environment with single node db plus asm storage used.
I googled everywhere , and a lot notes on ASM with RAC cluster clone provided but no document for ASM with single node.
Please help.

Single Node RAC on 11.2.0.3

Hi All,
i have implemented Rac One node with two machine(dbtest01,dbtest02) in 11.2.0.3 Redhat 5.3 one for online another one for offline. i have created TAF also.
dbtest01 is online and created one query
DECLARE
i number(36):=1;
begin
while(i<10000000)
loop
dbms_output.put_line(i);
i:=i+1;
end loop;
end;
i executed above query for test and i made relocate database using srvctl utility to dbtest02 machine.
session is relocated successfully with new session id...
above query getting stop in 25000 itself.
i want to make it continue that process...
also i tried to find Omotion utility in all the path.. couldn't find it... where will it be..
i want to relocate all the session without losing work.
from application i am getting disconnect after relocation.. application server need to restart to get work again...

Hi Friend
Point 1 : Omtion utility will not come with Oracle Binaries. We have to download the separate patch for that.
Patch is : p9004119_112010_<OS>
example : p9004119_112010_LINUX
To use Oracle RAC One Node Utilities, you must apply patch 9004119 to your 11.2.0.1 database home.
NOTE: You must have Oracle RAC software home on any node in the cluster where you could relocate (using Omotion) the Oracle RAC One Node instance or where it could failover to if the original node fails. You will be asked for this candidate list of nodes during the initialization of Oracle RAC One Node.
Solution is :
*1. Download the above patch*
*2. Download the this document - "ug_raconenode-2009.pdf" (Step By St*ep Document)

How many control file should be created in ASM for ORACLE 4 nodes RAC

We have a oracle 10G(10.2.0.4) database with 4 nodes locates ASM in redhat linux5.
The vendor created this RAC system with database.
I saw below infornation as
SQL> select name from GV_$CONTROLFILE;
NAME
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
It seems that each node with one control file.
I got a feedback that vender claimed SAN is very reliable.
I am new person for database at ASM for RAC.
Could you make a explain for this condition? Do I need to add ( mirror) another 2 control file into ASM?
The Oracle recommands that at least 2 contril files( best 3 files) in different place. This is true for signle instance.
How about RAC that database locates in ASM?
Please help me!!
Jim

You are fine using the standard three controlfiles in ASM, four is fine too, but it does not need to be tied to the number of instances as all the instances in a RAC database use the same controlfile (and its copies). ASM knows the controlfile type and will stripe each one in 128k pieces across as many volumes as it can. I much prefer to have my controlfiles in ASM, it prevents accidental deletion and generally makes DBA life easier.

NareshSet the log_archive_dest parameter as follows;
alter system set log_archive_dest_1='location=your_arch-loc' scope=spfile sid=* {In case the archived location is shared between both the nodes}
alter system set log_archive_dest_1='location=your_arch-loc' scope=spfile sid=SID1(& the for SID2) {In case the archive location is not shared and is on individual nodes.
Then shutdown the database on both the nodes
start the database in mount mode on node1
alter database archive log;
Now on Node2, start the database in mount mode
alter database archivelog
And finally open the database by firing alter database open command on both nodes

Install a grid infrastructure for a cluster for single node Windows Server

Hello,
Can you suggest me how to install a Oracle Single Node RAC 11g on a Windows Server 2008 x64 bits? It's for testing purposes and I don't need two nodes. I know that Linux is better, but my company only uses Windows servers. Our former consultant was able to do it, but didn't tell us how to and that server was lost.
I know that we have to install first Grid Infrastructure. Running the "Oracle Grid Infrastructure" installer, I could successfully install a "Grid Infrastructure for a Standalone Server". But that grid is not for a RAC database. When trying to install the Database software, it allowed to me to only install "Single instance database", not "Real Application Cluster database installation".
Running the "Oracle Grid Infrastructure" installer, I tried to select option:
"Install and Configure Grid Infrastructure for a Cluster" -> Typical Installation:
SCAN Name: SRVORAC-cluster
Validating SCAN information
INS-40922 Invalid SCAN Name - unresolvable to IP address.
Is it possible to install a grid infrastructure for a cluster for a single-node or one-node Windows Server ?

HI,
You probably have misconception about Single node RAC. This feature does not need that you have only one physical machine in a RAC, it actually means that in a RAC environment (2 or more nodes), you can run your database on only one node(single instance) and then later you can move this single instance to any other node of the RAC (so that you can do some patching on this node making your database available all the time). This also has some other benefits, see bellow.

Install 10gr2 ASM on single node, need clusterware installe first?

Install 10gr2 ASM on single node, Do I need install clusterware first?
When I install clusterware on single node, it shows " the specified nodes are not clusterable"
Thanks.

ASM and clusterware are two separate things. Clusterware is required only if you are setting up a RAC environment, is this your case? If you are just planning to use ASM then proceed with the RDBMS (database disk) install and use the DBCA to perform ASM configuration. It is assumed you have the raw devices ready to setup the ASM instance. Once the ASM instance is ready you can create the database to use the ASM disks.

10g single node install

How best to slice disk drives? Single Node install on a Sun V480 (2 cpu's @ 900mhz, 2 disk drives @ 36gb each), solaris operating system. For my test server I will install all 10g components. How best to distribute the 10g load (oraInventory, appserver, infrastructure, Metadata Repository) between the two disk drives?

Part of the installation involves the installer installing CRS software on the other nodes, creating the ASM and RAC instances and so on.
All this is done in an automated fashion - requiring each node to be prepped accordingly, ssh keys generated, public keys distributed and added to authorised keys and so on.
None of these installation steps (all critical) will be part of a "single node" RAC install.
In fact, the prepping part is even more critical and complex than the actual installation - if done properly the installation will be smooth and painless. If not... you will run into all kinds of problems. And this is often the case as one has to deal with getting the shared devices to be seen by all nodes, ensure consistent device mappings across all nodes, ensure that multipath (load balancing) I/O works, etc.
For this at least 2 nodes are required. For actual proper RAC testing itself, even 2 nodes do not suffice and at least 3 are needed.
IMO you are pretty much wasting your time as no real practical RAC installation lessons will be learned mucking about with RAC and a single VM.

Enable Archivelog Mode On 2 Node RAC DATABASE

hi,
We are having 2 Node Rac 10g Database Installed on Windows.
Currently the Database is in Non Archivelog Mode.
I want to convert it to Archivelog Mode.
I come to know the steps to convert cluster database to Archivelog mode.
i.e.
set archive parameters like Disk Location and Archivelog File format.
then Convert the database in Exclusive Mode
ALTER SYSTEM SET cluster_database=FALSE SCOPE=spfile;
then
C:\> srvctl stop database -d <Global_DB_SID>
then enable Archivelog Mode.
SQL> STARTUP MOUNT;
SQL> ARCHIVE LOG START;
SQL> ALTER DATABASE ARCHIVELOG;
SQL> ALTER DATABASE SET cluster_database=TRUE SCOPE=spfile;
SQL> SHUTDOWN IMMEDIATE
C:\> srvctl start database -d <Global_DB_SID>
But I am confuse with Do i need to RUN this commands in both the nodes seperatly or only on any one node.
Please Reply,

Node 1: OSERP1
Log on to OSERP1 Server
C:\> sqlplus sys/oracle@racdb2 as sysdba
SQL> ALTER SYSTEM SET log_archive_format='arch_%t_%s.arc' SCOPE=spfile ; -- this needs to be database wide
SQL > ALTER SYSTEM SET log_archive_dest_1='location=\\OSERP1\archive$\ERP1 ' SCOPE=spfile sid ='ERP1'; -- required quotes added
-- not required
SQL> ALTER SYSTEM SET cluster_database=FALSE SCOPE=spfile;

-- not required, and database wide setting
SQL> ALTER SYSTEM SET cluster_database=FALSE SCOPE=spfile;
Then following commands will be run connecting any of the instance
-- database has to be stopped first, if you stick to switching it to a non-cluster database
C:\> set ORACLE_SID=<local_instance_id>
C:\> sqlplus / as sysdba
SQL> STARTUP MOUNT;
-- wrong sequence of commands
SQL> ARCHIVE LOG START;
SQL> ALTER DATABASE ARCHIVELOG;
-- not required (see previous steps)
SQL> ALTER DATABASE SET cluster_database=TRUE SCOPE=spfile;
SQL> SHUTDOWN IMMEDIATE;
6. Start the cluster database.
C:\> srvctl start database -d <Global_DB_SID>
-- There is no such thing as a <Global_DB_SID>. There is a database name.
Please note your tnsnames.ora, in a standard install, needs to have the following service names.
ERP
ERP1
ERP2
I'm not sure why you have the non-standard service_name racdb2.
Somehow it looks like you both don't understand the RAC concept, and didn't understand my answer. I had to correct several things I already corrected in my previous response. I'm not sure why I'm not getting through.
