Oracle RAC simulation

Hi,
Does anyone know if you can still download that Oracle RAC simulation bundle from Oracle which includes a VM with ASM and some RAC nodes?
thanks

I think 3CPO is referring to VM image that Oracle use to have available externally (outside company). It is not available even internally now because it is obsolete, I believe. It was a VMWARE server image with 2 10g RAC nodes running on the same host, without external storage for ASM and OCR/VD. So, it was not a true RAC setup.
With 11gR2 RAC there are a few requirements that make such an image impossible to run. First off, if you want a full 11gR2 RAC system VM image you have to meet the external SCAN DNS requirement, plus it will need at least 8GB of RAM, three images (node1, node 2 plus an image for shared storage), 30GB of space.
So, if you want to use VM to build an 11gR2 RAC you have to either build it yourself on somewhat powerful machine - just like the other person suggested, or you can use these RAC simulators (for free, of course):

How to install Oracle RAC using 11gR2 on Win 7 32 bit from scratch?

Hiii,
I am a fresher and I have a win 7 system 32 bit with oracle 11gR2.
I want to install RAC using two or more servers but I dont know too much about it.
I tried to search on google but all they are giving information in pieces(for win 7) or about Linux(Please tell me why its all Linux everywhere not windows).
Please let me know if there any site where I can find step by step installation from scratch.
What are basic requirements(/software if needed).
Thank you.

Hi,
First of all forget about Windows!! Oracle is mainly designed for Linux systems. Oracle runs as real multi-process on Linux machines whereas on Windows it runs as a single process with multi-thread.
Memory usage - huge pages,single CPU run queue, dnfs, storage systems... etc. lots of concepts exists.
Besides Windows is one of the most poorly designed operating systems, you should use it only to watch cute kitten movies on youtube... Believe me, you wouldn't want to learn Oracle on Windows...
So, install virtualbox and then setup Oracle Enterprise Linux on it as a first step... By the way you have to deal with DNS server for release 11.X, RAC, you may start with 10g for now.
ORACLE-BASE has all the installation steps explained detailly, search for "oracle base rac install" on google.
I also explained on my blog, but it is a little bit advanced installation using ZFS storage simulator. DNS server installation is also explained: http://ilkertaysi.com/2013/11/11/oracle-rac-installation-with-zfs-storage/

Oracle RAC - Not getting performance(TPS) as we expect on insert/update

Hi All,
We got a problem while executing insert/update and delete queries with Oracle RAC system, we are not getting the TPS as we expected in Oracle RAC. The TPS of Oracle RAC (for insert/update and delete ) is less than as that of
single oracle system.
But while executing select queries, we are getting almost double TPS as that of Single Oracle System.
We have done server side and client side load balancing.
Can anyone knows to solve this strange behaviour? Shall we need to perform any other settings in ASM/ Oracle Nodes
for better performance on insert/update and delete queries.
The following is the Oracle RAC configuration
OS & Hardware :Windows 2008 R2 , Core 2 Du0 2.66GHz , 4 GB
Software : Oracle 11g 64 Bit R2 , Oracle Clusterware & ASM , Microsoft iSCSI initiator.
Storage Simulation : Xeon 4GB , 240 GB ,Win 2008 R2, Microsoft iSCSI Traget
Please help me to solve this. We are almost stuck with this situation.
Thanks
Roy

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

The query is re-issued as a flashback query and the client process can continue to fetch from the cursor. This is described in the Net Services Administrators Guide, the section on Transparent Application Failover.

I had this problem and resolved it by transporting the file to the installation server with the correct ftp datatype (binary).
On page 54 of the install guide (..Server\Oracle_Business_Intelligence\doc\doc\bi.1013\b31765.pdf) that comes with the installation files, there is an instruction to make sure that any ftp activity is done in binary.
This may not have occured with the license.xml file if you use a tool which offers the "feature" of automatic datatype recognition.
Hope this helps.

Oracle Upgrade from Oracle RAC 9.2.0.6 to Oracle 10.2.0.4

Hi All,
Currently, we are running 4 node Oracle RAC environment with below mentioned configuration.
OS: Sun Solaris 5.9
Hardware: Sun E2900
Oracle Version: 9.2.0.6
Veritas Cluster Server: 4.1
We want to upgrade Oracle version to 10g, and currently analyzing the options to perform this. The current database size is 1TB appx and we want to spend minimum application shutdown time running on this database.
As part of upgrade, we also need to upgrade Veritas Cluster Server from 4.1 to 5.1 to support Oracle 10g. It would be great help,, if someone can pass some guideline to perform this task.
We are currently thinking about piecemeal approach, where we can upgrade each node individually and then put them back to cluster. There are some complexities involved, and its really high risk approach.
Thanks a lot in advance for help
Regards,
Manoj

Orcale 10g RAC requires you to install Oracle Clusterware. Oracle Supports running it along side a 3rd party clustering software. Not sure why you're so anxious to upgrade Veritas Clusterware when it will be trivial on the 10g db hosts.

Try this. It worked for me.
Please keep in mind that you will need wait till each step finishes successfully before move to next one
For Step1 and 2, you can skip node(s) on which you didn't execute root.sh yet.
Step 1: As root, run "$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force" on all nodes, except the last one.
Step 2: As root, run "$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force -lastnode" on last node. This command will zero out OCR and VD disk also.
Step 3: As root, run $GRID_HOME/root.sh on all node one by one

Oracle RAC with ASM install failure

Hi Guy's
I've just rebuilt an Oracle RAC system, i've built this system many times and have the build documented. I usually follow the build doc to the tee and everything works fine. I have now been asked to rebuild the system to go into the production evironment. This is a two server standard RAC setup using ASM. We have a HP MSA500 shared storage setup. I've run the cluster verification tool and all the checks have come out fine. Whilst installing the clusterware i get a failed error message whilst it try's to confiure the Oracle Clusterware Configuration Assistant.
The error message i get is:
Command = C:\Windows\system 32\cmd\C Call E:\Oracle\Product\10.2.0\crs\install\crssetup.config.bat
PROT-1:Failed to intialize OCR Config
STEP 1 Checking status of CRS cluster
STEP 2 Creating directories (E:\Oracle\Product\10.2.0\Crs
STEP 3 Configuring OCR repository
ocr upgrade failed with (-1)
I've done this build many times and never seen this error. From what i've read on the internet it looks like it could be something up with my shared storage but i dont know what.
Any help would be greatly appreciated
Thanks

ASM instances on 2 node Oracle RAC 10g r2 on Red Hat 4 u1

Hi all
I'm experiencing a problem in configuring diskgroups under +ASM instances on a two node Oracle RAC.
I followed the official guide and also official documents from metalink site, but i'm stuck with the visibility of asm disks.
I created fake disks on nfs with Netapp certified storage binding them to block device with the usual trick "losetup /dev/loopX /nfs/disk1 " ,
run "oracleasm createdisk DISKX /dev/loopX" on one node and
"oracleasm scandisks" on the other one.
With "oracleasm listdisks" i can see the disks at OS level in both nodes , but , when i try to create and mount diskgroup in the ASM instances , on the instance on which i create the diskgroup all is well, but the other one doesn't see the disks at all, and diskgroup mount fails with :
ERROR: no PST quorum in group 1: required 2, found 0
Tue Sep 20 16:22:32 2005
NOTE: cache dismounting group 1/0x6F88595E (DG1)

any help would be appreciated
thanks a lot.

OIM 9.1.0.2 - Weblogic JDBC Multi Data Sources for Oracle RAC

Does OIM OIM 9.1.0.2 BP07 support Weblogic JDBC Multi Data Sources (Services>JDBC>Multi Data Sources) for Oracle RAC instead of inserting the "Oracle RAC JDBC URL" on JDBC Data Sources for xlDS and xlXADS (Services>JDBC>Data Sources> xlDS|xlXADS > Connection Poll> URL) ?
If yes, is there are any other modifications that need to be made on OIM, or just changing the data sources?

Yes, it's supported. You install against one instance directly of the Rac Server. Then you update the config.xml file and the jdbc resource in your weblogic server with the full rac address. It is documented for installation against RAC. http://docs.oracle.com/cd/E14049_01/doc.9101/e14047/database.htm#insertedID2

Encountered ora-29701 during Sun Cluster for Oracle RAC 9.2.0.7 startup (UR

Hi all,
Need some help from all out there
In our Sun Cluster 3.1 Data Service for Oracle RAC 9.2.0.7 (Solaris 9) configuration, my team had encountered
ora-29701 *Unable to connect to Cluster Manager*
during the startup of the Oracle RAC database instances on the Oracle RAC Server resources.
We tried the attached workaround by Oracle. This workaround works well for the 1^st time but it doesnt work anymore when the server is rebooted.
Kindly help me to check whether anyone encounter the same problem as the above and able to resolve. Thanks.

Problem statement:
ORA-29701 DURING DATABASE CREATION AFTER APPLYING 9.2.0.6 PATCHSET
*** 03/25/05 07:32 am ***
TAR:
PROBLEM:
Customer applied 9.2.0.6 patchset over 9.2.0.4 patchset.
While creating the database, customer receives following error:
ORA-29701: unable to connect to Cluster Manager
However, if customer goes from 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the problem does not occur.
DIAGNOSTIC ANALYSIS:
It seems that the problem is with libskgxn9.so shared library.
For 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the install log shows the following:
installActions2005-03-22_03-44-42PM.log:,

For 9.2.0.4 -> 9.2.0.6, install log shows:
installActions2005-03-22_04-13-03PM.log:, [libcmdll.so ->%ORACLE_HOME%/lib/libskgxn9.so 64274 plats=1=>[46] langs=-554696704=>[en]] does not exist.
This means that while patching from 9.2.0.4 -> 9.2.0.5, Installer copies the libcmdll.so library into libskgxn9.so, while patching from 9.2.0.4 -> 9.2.0.6 does not.
ORACM is located in /app/oracle/ORACM which is different than ORACLE_HOME in customer's environment.
WORKAROUND:
Customer is using the following workaround:
cd $ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk rac_on ioracle ipc_udp

Oracle RAC 11g on Windows 2008 64 bit - blue screen error on both nodes

Hi Everyone,
I installed Oracle RAC 11g on Windows 2008 64 bit, The installation was successfull and crs_state -t shows all services in two nodes are online.
When executed a select query with 100 sessions( For performance evaluation using Transaction generator ) ,the machine got crashed and blue screen is appeared on two nodes. I restrated the machines and and starts the same evaluation ,bt the same bug is repeating.
Can anyone suggest a solution to solve this issue? Is our hardware is not sufficient ? Shall we need to perform any
specific settings in Oracle RAC setup for performance evaluations?
Is our settings for load balancing is not enough? ( We added "Load Balancing= On" on tnsnames.ora on client for load
balancing)
The following machine configuration is used for Oracle RAC setup
Intel Core 2 Duo 2.66 GHz,
Ram :4GB.
OS : windows 2008 Server 64 Bit

which documentation you have followed?
