I tried reinstalling again and it worked on Vmware Server.Some oracle products are certified on Oracle VM , but not RAC at the moment.
You can download Oracle VM from otn.oracle.com

Hi Naveen,
We would like to migrate our Siebel database from Sql Server 2005 to Oracle 11g RAC. Can you suggest the best way to do that ?You will need much more which suggestions.
You will need a Siebel professional which has done this type of migration. Migrating the Database is not a task so hard, after migrating your environment should be functional and healthy it is usually the task problematic.
The hardware can be changed if needed. Can you please suggest the best approach ?We can recommend the minimum recommended, but this documentation already does, you need to do a analysis on your environment and ask a vendor Siebel tell the which is recommended for you and how to find the best "number" for you, in your case is very hard because everything changes.

Install Oracle 11G, RAC with VMWare, APPS R12, and OBIEE on one server?

Dear Experts,
I'm looking to upgrade my skills, and want to learn more of:
Oracle 11G, RAC, VMWare, APPS R12, and OBIEE
My server has two quad cores (8 CPU altogether) and 16 gigs of RAM.
Years ago, I took a shots at installing RAC on multiple servers and firewire.
One thing I remember was that after I installed RAC, I was not able to use the database unless I enabled all the RAC processes on the server. So, I was not able to just boot the database and use it in the traditional single server manner.
Which I will also want to do.
1) Does this symptom/aspect/characteristic of RAC install still exist?
2) Is it realistic to install all this software on one server?
If so, what is the order of operations for the install?
3) If I have to prioritize, I'd like to install
Oracle 11G, OBIEE, and APPS R12,
Would installing R12 and OBIEE on the same server present any conflicts or issues?
If not, what is the order of operations for the install?
11G, R12, then OBIEE?
Thanks a lot!

Hi,
1) Does this symptom/aspect/characteristic of RAC install still exist?No.
2) Is it realistic to install all this software on one server?
If so, what is the order of operations for the install?For learning/traning/demonstration purpose you can Install all these software on same machine.
3) If I have to prioritize, I'd like to install
Oracle 11G, OBIEE, and APPS R12,
Would installing R12 and OBIEE on the same server present any conflicts or issues?
If not, what is the order of operations for the install?
11G, R12, then OBIEE?There will not be any conflicts. I would suggest you to select vmware or virtual box in order to configure all these sw's.
I have done such a configuration on my laptop with i7 Quad processor, 16GB RAM and 640 GB HDD.
I have Installed 2 node RAC, 2 Node ERP and all are running smoothly without any issues.

I would like to migrate an entire database from MySQL to my new Oracle 11g RAC. How do I do it?

Hi Turloch,

I am having a hard time migrating data from mysql maybe due to table size. I got mysql tables with more than 20M and the PC am running the sqldeveloper is running out of memory every time I try to migrate the tables.
Can you share some experience migrating from MySQL to Oracle?
Thank You.

Q) Can the links of Oracle RAC installation over Unix and Linux be taken as base?? As i haven't seen any doc for installing 11g RAC on Solaris, where as it was provided in Oracle 10g.yes, you need to consider Oracle RAC installation over Unix and Linux be taken as base as base document.

Can Oracle 11g RAC support 2 separate databases?

1. Can Oracle 11g RAC support 2 separate databases given that it asks for SCAN ip for cluster with a single Listener port number?
2. Will the Oracle 11.2 database connections work successfully if I setup a mandatory DNS server within the Oracle RAC servers?
I'm leading a team for a 11g project and appreciate responses.
Thanks
Satish.

No Real Application Cluster technology has ever supported more than one database.Quite untrue.
I know that both you and Tom Kyte take the stand that a cluster should have only 1 instance per node.
That doesn't mean that it is not possible to have more than one database in a cluster -- i.e more than one instance in a node.
That doesn't mean that it must always be so. Installing a separate cluster and additional EE + RAC licences for a separate database can be quite expensive. Of course, your reply is "consolidate". That is another debate that has been going on for years.
A discussion on multiple databases on RAC is also at

Oracle 11g RAC on CentOS 5.2 - Node isnt working after hardware failure

Hi,
We have a 2-node Oracle RAC 11g running on identical nodes with Centos 5.2 as operating system.
Due to a drive failure and a reboot yesterday, the ASM disk, which is onnected via iSCSI, changed from sdd to sdc in name - (the faulty raid drive was removed, thus the change).
The oracle services didnt start, which appeard perfectly logical at the time, given that the ASM disk suddenly wasnt where it was supposed to be, but even today after a replacement disk was inserted, the RAID rebuilt + with the ASM disk back to its original naming in /dev/; the node doesnt seem to work properly. Some of the oracle services are running, but there seems to be a problem with the listener, which might also explain why the node does not set it's virtual ip after starting up.
Luckily, the other one is unaffected and is working perfectly fine..
I'm far from having a clue about oracle, it was sheer luck (that, and the very usable documentation by oracle) that i managed to get that cluster running in the first place... I know my way around linux, so if it's a operating system related problem i'll be able to fix it, but i cant figure out what the problem with oracle is.
The listener doesnt seem to be running

Hi,
As usual, as soon as i post a problem in some board, i find the solution myself.
Although this way isnt really "linuxy", deleting the listener with the netCA tool and adding a new one solved it.
