Migrate Oracle RAC to Vmware
Hi;
Am wondering if anyone has ever tried migrating a present RAC environment (2 node cluster using ASM accessing a SAN for the data and flash). I know I can convert the physicals but all documentation I have found on disk sharing points to creating the disks and doing the multi-writer option. This is not possible when the added disk is using a Raw Device Mapping which is my only option when presenting the LUNS to the host server. This is an ora10g and ESXi 5.1.
Thanks
I think install a new RAC in vmware and migrate data from old db use export/import or sqlload is a better and safer choice .

SAP - Oracle RAC - Linux - VMware
Hi,
we would like to install SAP on a virtual environment (VMware) on Linux RedHat platform.
For the database, Oracle RAC is certified with OCFS2 (1.6) only with Oracle Linux and not RedHat Linux 5.
Can we intstall Oracle RAC database on 2 nodes with Oracle Linux and OCFS2 and other SAP components on Redhat Linux 5 ?
Are there any issues with SAP matrix compatibility ?
Thank you!
DanHi Audun,
Thank you for the links.
I can see the ASM support is new (2.2.2011)
On Note 527843 from 25.01.2011 - Oracle RAC support in the SAP environment
Using raw devices and ASM (Automatic Storage Management) is not supported in the SAP environment. In the case of ASM, there is an exception regarding the Oracle Cluster Registry (OCR) and the voting disks
and
on Note 1550133 - Oracle Automatic Storage Management (ASM) from 2 Feb 2011 they support ASM but with restrictions:
ACFS is required for RAC installations with ASM
To use ASM now, you have to migrate your database to ASM manually
Some important functions of SAP BR*Tools like backup, restore, recovery, tablespace and datafile management are not supported at the moment
Support for tablespace and datafile management is planned for Q2/2011
Also ASM instance will introduce another layer in the system with its problems, failures and resources consumption. I see on the Oracle Metalink alot of problems related to ASM. From the marketin point of view is ok, let's oracle do everything but I think if you will keep it simple it will be better.
I didn't figure out if you can directly install Oracle 11.2.0.2, they say "Allows direct SAP system installations with Oracle 11.2"
We have a vBlock hardware with flash disks as FAST Cache so I believe with 1TB of cache IO will not be a problem.
Thank you!

Oracle RAC on VMWare vs. Virtualbox
hello,
has anyone tested Oracle RAC DB 11g performance on VMWare server and on Virtualbox?
I wonder which virtual solution is faster.I have created several Virtual Machines on my laptop using both VMWare Server 2 and Virtual Box (various versions utilized over time). I have found that the memory overhead of Virtual Box is lower then that of VMWare Server can not answer why I can jsut say that I have more free memory with Virtual Box then with VMWare Server 2 when using Virtual Machines with same configuration. On my Laptop I have not noticed a large performance difference between virtual box and VM Ware Server for Virtual Machines of like resource allocation and activity types, the performance appears to vary more by the resource consumption and activity executing within the VM. If I had to give a gut feel for an overall local VM tool, I like virtual box better then VMWare Server. I also see Virtual Box Updates coming, however not seen an update to VM Ware Server in a while. Hope this helps

I have successfully installed Oracle Rac clusterware and database on Vmware using Oracle Red-Hat enterprise Linux -5.
I have a doubt here, that when I restart my setup the disks in Asm are not mounted automatically during service start, so I have to first manually mount my disks in ASM instance.
The thing goes smooth after re-issuing the command
./crsctl start -all
My Database instance goes up
So I have a question on How to configure the ASM instance so that the Disk mounts automatically when the service is starting up.
Thanks,
Varunplease check value of ASM_DISKGROUPS parameter in ASM pfile.
ASM_DISKGROUPS specifies a list of names of disk groups to be mounted by an Automatic Storage Management instance at instance startup or when an ALTER DISKGROUP ALL MOUNT statement is issued.

Migrate Oracle Rac 11.1.0.6 SE to Oracle Rac 11.2 EE
Hi,
is there some guideline to migrate e 11.1.0.6 RAC Standard Edition with ASM to a 11.2.0 RAC Enterprise Editon?
Database is almost 800gb, index included.
Some best practice? Some suggestion? Some links?
Thanks in advance,
Samuel RabiniOr from 11.1.0.6 Standard to 11.1.0.6 Enterprise.
I can find anything on internet to do such a migration.
Thanks in advance.

Putting Oracle Apps 11i on 10g RAC using VMware
Hello All,
I am building a Oracle Applications 11i on 10g RAC, using VMware..Since there aren't any docs I could find on internet explaining how to do this, I have come up with my own. I have combined the MEtalink doc:362135.1 and the docs describing building a 10gRAC "database" using VMware..I want to know if the below process is good enough to get the required results:
Steps:
-Install VMware on HOST m/c
-Configure 1st virtual m/c, say RAC1
-Install RHEL on RAC1
-Install 11i with 9i database on the local SCSI bus- SCSI 0:0
-Install VMware client tools
-Create a new ethernet adapter(for private interconnect) on RAC1
-Create shared disks on RAC1
-Partition the disks
-Add the disks as RAW devices in /etc/rawdevices
-Clone RAC1 to a new virtual m/c,say RAC2
-Delete the 11i apps directories from its local SCSI bus..since these would be redundant on RAC2
-Install Clusterware s/w on RAC1 using the same oraInventory that is used by the Applications 11i installation-
-Install the 10g DB software and create ASM instances using dbca
-Install Database componenets from 10g companion CD
-Upgrade CRS abd DB s/w to 10.2.0.4
-Upgrade the 9i database to 10g using dbua from the 10g ORACLE_HOME
-Convert the newly upgraded 10g databse to RAC using the rconfig tool
-Post migration steps for RAC
-Enable AutoConfig on the Applications Database tier
- Follow the "Establish Applications Environment for RAC" section from Doc:362135.1
-Configure PArallel Concurrent Processing(PCP)
Thanks,
Sandeep(Considering that there are only 2 nodes the scenario the steps would be as follows:
1. Install RAC using the steps provided at the link:
http://oracle-base.com/articles/10g/OracleDB10gR2RACInstallationOnCentos4UsingVMware.php
2.On RAC1 create a single instance of Oracle 11i (Both DB and Apps are on the same node)
3. Follow the steps outlined in the Note:362135.1
One thing to note is that the steps are the same whether the nodes are real or virtual. -
Domain migration of Oracle RAC nodes on windows 2008
Hello masters,
We are planning to migrate servers from old domain to a new domain due to company name change. That is, our DB servers named like db-node-x.old-domain.com will be migrated to db-node-x.new-domain.com. The servers are all on Windows 2008 R2 and Oracle RAC 11g2. As dba, i have no idea about what will happen to DBs. Please let me know any possible solutions?

Bt the machine got crashed ,when executed a select query with 100 sessions( For performance evaluation using TG). A blue screen is appeared on two nodes. So i am not able to evaluate the performance.
Can you please tell any suggesstions to solve this issue? Is our hardware is not sufficient? Or any software settings has to be done?. I tried most of hte technique ,bt the problem still exists.
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
Oracle RAC , Clusterware 11g R2 64 Bit.i guess you have installed/configured RAC using VMware. i guess, the problem is with your RAM size. how much disk space and RAM size you have allocated for each machine?
which documentation you have followed? -

Oracle-10g RAC on VMware installed on Windows-7(Host)
Hi,
My host OS is Windows-7. Docs. posted on this forum for RAC on VMware says: your Host OS should be Centos OS and in which you will install VMware and Client tools also. In this way u can clone another RAC2 machine.
But I have Oracle VM Virtual Box installed on Windows-7. Another is VMware Player installed on Windows-7.
I want to install Oracle-10g RAC on my Laptop. Please any suggestions or Docs. related to this.
ShakeelHi,
while this is a documentation of 11gR2 it gives enough information on how to setup a RAC in a VBox environment:

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.
Aman....
