Oracle 11g R2 RAC on vmware

Hi All,
I have read many blogs and article about installing Oracle 11g R2 RAC on vmware. For self learning process what should be minimum configuration of hardware.
Minimum physical memory will be 8 GB what is minumum processor required ( 2 Cores / 4 Threads) or ( 4 Cores / 8 Threads)?
Native operating system will be Windows 7 64 bit.
Thx.

You wouldn't be doing much with the processors so it won' t matter hugely having a dual or quad core. As long as there is sufficient RAM(like 8gig) , you should be fine. Try to get SSD if you want more faster performance from the machine in terms of IO.

Snapshot standby database in oracle 11g r2 RAC

Folks,
i am just wondering if the process is same for standalone and RAC snapshot standby database.
We have a DR test
1 / I just converted the standalone DR on 11g to snapshot standby database for users to do some testing and reverted back to physical standby after test was done. i folllowed metalink note ID 443720.1
2/ now there is anotherDR test where we have 2 node prod and 2 node DR on oracle 11g rel2 RAC, so not sure we can follow the same process that i used for 11g standalone database. If somebody have done this on RAC, would you please provide the steps ?
Thanks in advance

I haven't done a Snapshot Standby (RAC or non-RAC). But I see no reason why it shouldn't work with a RAC Standby either.
The command is a Database level command, not an Instance level command.

ASM Installation on Oracle 11g Clusterware (RAC) environment

Hi All,
I am trying to setup Oracle 11g Standared Edition RAC+ASM on RedHat Linux 5.0 VM ware box. As part of this RAC setup successfully completed. For this i have used raw devices and mounted using NFS.
In many of forumns i have read that ASM installtion on a cluster envioronmnet is different than non cluster environment.
I dont know how to start ASM installtion on RAC environment. Please share any documents if you have?
Thanks,
Rakesh

will the steps need to be done on two nodes of cluster or it is sufficient on first node.
"raw device" for OCR, VOTE, SPFILE_FOR ASM and ASM DISKGROUPs
before do "raw devices" you have to fdisk(make partitions) on share storages
node1:
# fdisk /dev/sdf
# ls /dev/sdf*
node2:
# ls /dev/sdf*
don't find...,so just fdisk -> l and -> w
fdisk how? http://linux.about.com/od/commands/l/blcmdl8_fdisk.htm
Example: /etc/sysconfig/rawdevices do it every nodes
#Oracle OCR File +~280M+
/dev/raw/raw1 /dev/sdf1
#Oracle Voting File +~280M+
/dev/raw/raw2 /dev/sdf2
#Oracle ASM spfile ~50M+
/dev/raw/raw3 /dev/sdf3
#Oracle ASM DISK Group1
/dev/raw/raw4 /dev/sdg1
#Oracle ASM DISK Group2
/dev/raw/raw5 /dev/sdh1
And oracle user.. can read /dev/raw/raw* You should find on every nodes
http://oraclepitstop.wordpress.com/2008/02/15/raw-devices-on-rhel-5-or-oel-5/
ls -la /dev/raw/raw*
crw-rw---- 1 root oinstall 162, 1 Jan 13 12:53 /dev/raw/raw1
crw-rw---- 1 oracle oinstall 162, 2 Jan 13 12:53 /dev/raw/raw2
crw-rw---- 1 oracle oinstall 162, 3 Jan 13 12:53 /dev/raw/raw3
crw-rw---- 1 oracle oinstall 163, 1 Jan 13 12:53 /dev/raw/raw4
crw-rw---- 1 oracle oinstall 164, 1 Jan 13 12:53 /dev/raw/raw5
do it on node1 but you have to pass phrase on every nodes Before
http://www.puddingonline.com/~dave/publications/SSH-with-Keys-HOWTO/document/html/SSH-with-Keys-HOWTO-5.html
example:
node01:
$ ssh node01 hostname
node01
$ ssh node02 hostname
node02
- Install + Setup Clusterware:
OCR = /dev/raw/raw1
VOTE = /dev/raw/raw2
- Install Oracle Database for ASM Home
spfile for ASM = /dev/raw/raw3
- after ASM started... create disk groups from /dev/raw/raw4 and /dev/raw/raw5
- Install Oracle Database for RDBMS Home
- Create Database to use ASM diskgroups
http://www.oracle-base.com/articles/11g/OracleDB11gR1RACInstallationOnRHEL5UsingVMwareESXAndNFS.php
Did you followed the same procedure to set up Oracle 11g RAC+ASM on RHEL 5.0.I'd done(test 11gRAC) it on RHEL 4 + 11g + ASM(on raw device)
on production, I use ASMlib... + ASM + 10g

Problems connecting to Oracle 11g R1 RAC

Hi everybody
In my factory we hava a web aplication called Matrix one that is connected to an oracle database 11g. This aplication uses Weblogic 9.2.3 to load the web pages. Until now we had an oracle running in one server, but now we have put an oracle rac system. The application works fine with this new situatin, but there ar parts of the system that don´t work. We have made our own applicatons that use thin jdbc driver to connect to database, but now when we connected to the rac sometimes the connection is established well but most of times the conecction failed. The error that weblogic returns is "connection refused".
I´ve modified the startweblogic.cmd to use the las jdbc driver but the result is the same. My connection is the folloowing:
Connection conn = null;
String cadenaConexion = "";
try{
OracleDataSource ods = new OracleDataSource();
ods.setUser(user);
ods.setPassword(Pass);
cadenaConexion = "jdbc:oracle:thin:@(DESCRIPTION=";
cadenaConexion = cadenaConexion + "(ADDRESS=(PROTOCOL=TCP)(HOST=" + Server1 +")(PORT=1521))";
cadenaConexion = cadenaConexion + "(ADDRESS=(PROTOCOL=TCP)(HOST=" + Server2 +")(PORT=1521))";
cadenaConexion = cadenaConexion + "(LOAD_BALANCE=on)";
cadenaConexion = cadenaConexion + "(CONNECT_DATA=(SERVER=dedicated)(SERVICE_NAME="+Service_Name+")";
cadenaConexion = cadenaConexion + "(FAILOVER_MODE=(TYPE=Select)(METHOD=basic)(RETRIES=180)(DELAY=5))))";
ods.setURL(cadenaConexion);
return con;
}catch (Exception e){
e.printStackTrace();
return (null);
This is my startWeblogic.cmd:

I´ve tried to use the Oci driver but then the error is diferent "java.lang.UnsatisfiedLinkError: no ocijdbc9 in java.library.path".
I´ve red a lot of messages in forums but >I haven´t found the solution.
Anybody could help me please?
Thanks in advance
Sorry for my English.

I´ve tried to use the Oci driver but then the error is diferent "java.lang.UnsatisfiedLinkError: no ocijdbc9 in java.library.path".OCI requires a Oracle shared library (nothing to do with java.)
returns is "connection refused".Which suggests a network problem. Given that you have added at least one new box to your network, how it was added would be the problem. Such as if a network infrastructure box is having an intermittent failure.

SCAN in Oracle 11g R2 RAC

Hi All,
Actually i am not having much idea on either Linux administration nor DB administration, Actually i am Test engg and my requirement is to setup Oracle 11gR2 RAC on Linux machine.
I have followed steps in http://www.oracle-base.com/articles/11g/OracleDB11gR2RACInstallationOnLinuxUsingNFS.php
Actually i am not clear with SCAN. Given some IP address of the main box names of the nodes.
Please can any one explain what should be the IP address that needs to enter as SCAN in /etc/hosts file.

I have used the IP address of the VM host which is having 2 nodes, It could be able to see in nslookup but not pingable.
Placed the same in /etc/hosts of both nodes. After installation of Grid infrastructure which i have issued ifconfig i could able to see the SACN IP address
Node 1:
eth0 : Public IP Address
eth0:2 Virtual IP address
eh0:3 SCAN IP address
eth1: Private IP
Node 2:
eth0 : Public IP Address
eth0:1 Virtual IP address
eth1: Private IP
Please let me know if the shown thing is correct or i did some mistake.

Identical database & instance names in Oracle 11g R2 RAC

Hi ,
     We are migrating our EBS 11i (11.5.10 CU 2) and oracle 11gr2 (11.2.0.3) database (database only) which is currently on Solaris to Linux. Currently the database is NON-RAC and as a part of the migration we are converting it in to a 5 Node RAC. A lot of third party interfaces connected to this environment are using hard coded database name. Unfortunately due to the project time lines it's impossible to change those applications within the migration timeline. In order to ensure that they don't break we are thinking of keeping one instance name same as database name so those applications can continue to function without any change to their code. We are aware that this would compromise on fail over capabilities for those applications but we are ok with that.
This what we have in mind: Create 5 PROD instance named as PROD, PROD1,PROD2, PROD3 & PROD4. PROD being the name of the database also. I would like to know:
1) Is this configuration allowed i.e., is it ok to have one instance with the same name as database?
2) We will be creating a 5 node Data gaurd environment for this so what will be the impact of such a naming on it?
3) Since it's an EBS environment will there be any issues with application configuration?   Our application architecture will be as below:
6 application nodes - Two for concurrent managers, two for forms & web & two external nodes
The two CM app nodes will be tied to two database instances using Services
Remaining app nodes will connect to the remaining 3 instances once again using services.
We will be configuring services using "vip" instead of scan names.
4) What will be the impact if the node having the instance name same as database name goes down?
5) Any other areas to worry about with such a configuration say like cluster services, 3rd partyinterfaces/applications?
Please let me know if you have any idea of such a configuration.
regards
pramod

Brian, rchem & Martin thanks for your responses. Appreciate it much. I was thinking about the service alternative but unfortunately I understand from my customer that their applications have hard coded database (used as a instance name) name. All they are saying is that their applications are using instance name instead of database name without providing much details on how it's being used. I just know that there 180 applications... Oracle & non Oracle based in which the instance name is hard coded, but haven't got answers to my questions on how it's hard coded i.e., is it being pulled from the database using a hard coded query like "select instance_name from v$instance" or is it a part of some variable in the script/application etc., and what it's being used for (later) within the application. Answers to those question will help in deciding what should be the right strategy but since I am short of time I thought of this and wanted to know if anybody has implemented or come across a similar architecture.
I am creating services and using them in my EBS application ifile thereby avoiding SID but agree with you on the node failure part as I haven't tested this new set up yet.
Martin,
          You are right, they are using the database name as a SID in their application hence the above need. My cluster version is 11.2.0.4.0 (both Active & Software versions). The source database on solaris is 11.2.0.3 Non RAC, it's going to be upgraded to 11.2.0.4 before conversion/migration hence I have installed & created a 11.2.04 RAC environment as a part of POC/Load testing.

Error while installing Oracle 11g R2 RAC

Hi,
I am getting following error while trying to provide Oracle software locatio.
[INS-20702] Unexpected Internal driver error
Cause - A call to cluster verification utility failed.
Following are the steps i have followed:
1. Using NFS mount created a share mount point between two nodes.
2. Used OCFS2 for OCR
3. Pointed local location at the time of installing Grid infrastructure.
4. After executing rootInventory.sh and root.sh using root user on both nodes i could not able to create any folder in NFS mount and OCR location.
5. Used NFS mount point /u01/app/...etc location for Oracle software location at the time of software installation.
Observed the above error.
Note: Got the same error when tried to give "grid" location at the time of "Grid software" location, so re-directed it to local home. But able to see the same content in the another node aswell.
Please Help me

Cause
Common cause is OS user who is performing the installation doesn't have write access to file in /tmp/CVU_11.2.0.1.0_user folder.
For example, if oracle is the user that's performing installation but couldn't write to file in /tmp/CVU_11.2.0.1.0_oracle, the error will be reported.
Solution
To fix the issue, remove folder /tmp/CVU_11.2.0.1.0_user and try runInstaller again.
For more information, see the Oracle Metalink document: 970166.1

Oracle 11g RAC on Windows 2008 R2 VMware EXS 3.5 virtual machines

Hi,
We are planning to Install Oracle 11g R2 RAC on two VMware EXS 3.5 Windows 2008 R2 servers.
Having trouble while assigning the storage to the servers, the Raw Device Mapping feature in the VMware is greyed out and we cannot assign the disks to the Virtual servers, the disks are allocated to the Vmware Host machine from the SAN (HP EVA).
Please guide me the best approach for the RAC configuration on VMware EXS 3.5 Win 2008 R2 Guest servers.
any help will be highly appreceiated.
Thanks.

Hi,
Is this implementation to production environment?
Be aware:
Is Oracle RAC on VMware supported? No, we do not support Oracle Software including Oracle RAC on VMWare.
Aside from the support restrictions for the database on VMWare outlined in Metalink Note 249212.1, there are technical restrictions that prevent the certification of Oracle RAC in a VMWare environment.

Is this possible to do - so I can learn about Oracle 11g R2 RAC operation, tuning, setup and maintenance?Yes, possible to setup.
No, you are unlikely to learn anything of value ito tuning and maintenance as the environment does not run on actual cluster h/w that are used in real world RAC clusters. For example, huge pages, jumbo frames - pretty meaningless in a VM for tuning Oracle RAC. Bonding of Interconnect Interfaces and pulling the plug - pretty much useless. What about running multiple I/O paths to the cluster's storage server? Using RDS for Interconnect instead of UDP? Etc. Etc.
RAC is only as performant, scalable and robust as the h/w components it is build on. I cannot see any value in virtualising this and expecting to gain real insight to RAC performance management and tuning. Best one can expect is familiarisation with installation prerequisites, the installation steps and setting up the database. I question if any more value than that can be obtained from a single PC virtualised RAC environment.

Oracle 11g in Virtual Machine

Hi Gurus,
I would like to gather input from you, what is the pro and con, advantages and disadvantages for putting Oracle 11g in Virtual Machine (VMWare, Oracle VM, Virtual Box, etc.)
and will there be any licensing issue with this.
Currently we have CPU Based license for our Production and Named User license for the Dev.
thanks in advance for your time.
Lie

If you put Oracle db in VMWare then you have a non-certified configuration, and you could be alone (I mean without Oracle support) if you have a problem than Oracle support cannot reproduce in a certified configuration. I would avoid a non-certified configuration for a production environment.
So, two choices :
* go for Oracle VM
* go without VM at all
