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

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

ORACLE 10G 2 Node RAC on servers AB to 3 node 11GR2 RAC on new servers XYZ

Hi Gurus ,
We have a business requirement to upgrade existing oracle 10.2.0.4 2 Node RAC on servers A,B (HP UX 11.31 ) to 3 Node ORACLE 11GR2 on new Servers X,Y and Z(Linux and servers are from different vendor)
We don't have ASM.We have RAW file system
Now this has to be done with near zero down time.This is a very busy OLTP System.Golden Gate is not an option as Management is not going for it this time.
Storage is same for everything.I am thinking of the following ways.Please let me know if you have any better plan or if you want to correct my existing plan
Initially i thought of this way and i immediately answered myself
Plan A
1 ) Storage copy (BC etc..) exising 10g RAC Database files on A,B to new volumes allocated to Servers X,Y and Z ( I don't think it's possible as OS is different.I am not sure whether copying this way is possible or not , even if possible i am not sure whether new OS can identify these files or not)
2 ) upgrade 2 Node 10.2.0.4 on X,Y to 11GR2 .
3 ) Add a Database Node on Z
Plan B is
1) Build 3 Node brand new 11GR2 on X,Y and Z
2 ) Plan for how can you replicate the data ( This has to be a logical way)
a ) RMAN - Very time consuming as this is >50 TB Database
b) Golden Gate - Not an option.Even if we can use it , i see there are so many logical issues with golden gate
c) Expdp/impdp - forget about it :)
d) physical standby (Versions are different.If it is same version and Same OS then would have been best bet)
What would be the ideal way to do this with minium down time and with out golden gate
I think something can be done on the lines of PLAN A itself.
Requesting your help Gurus
Thanks

Hi,
Have you considered possibility to setup a logical standby and do rolling upgrade ?
Please have a look at the following:
1) http://www.oracle.com/technetwork/database/features/availability/maa-wp-11g-transientlogicalrollingu-1-131927.pdf
2) http://www.oracle.com/technetwork/database/features/availability/maa-wp-11g-upgrades-made-easy-131972.pdf
If you can practice on test setup, it looks a faster option than the others.

Oracle insert sessions not failover to node1 in 11gr2 suse linux 2 node rac

Hi all,
I already setup a 2 node oracle 11gr2 rac and setup is installaed fine. in baseline testing insert sessions are not failovering to the node1. scenario i do as follows.
Scenario 1 - We ran an insert query in both Nodes and unplugged the Node2 interconnect wires from the server. In which case the Node2 insert session should failover to Node1 without any interruption to the users and the Node2 CRS( Cluster Ready Services) should reboot.
Scenario 2 - We ran the insert queries and unplugged Node 1 interconnections from the server. In this scenario also Node2 CRS should reboot and the insert session should failover to Node2.
please let me know any one have face this issue.
Regards,
Kanchana.

Hi,
I already created the TAF service and try to failover it. Node going down and nothing will happen. But the insert query of the client machine will hand and not getting any error. We using VIP for local and remote listner as well. because still not configure the DNS.

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 11G RAC 2 node

Hi,

I don't understand why i see a problem only with SYSDBA and not any other account. Does this mean i can go ahead with account creation etc. I need to use this DB to install my zenworks application. I've been struggling with all of this for a month now.
Please help!
Thanks so much

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.

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

Oracle 11gR2 RAC setup with ASM option running on two nodes . Seeking help

Hi ,
Recently we have migrated to 11gR2 extended RAC for one of our application using ASM . Its a two node RAC setup . We are using ASM Normal redundancy feature maintaining two failure group .
I need few clarification regarding our new DR set up .
We are planning to have EMC SRDF replication from any of node storage ( Either 1 or 2) to the DR disks .
Its stright to use when we use the normal file systems . In case of ASM , I am not sure how this replication will work ? and on which level the replication should happen ?
Do i need an ASM instance up and running on DR server , Which will recognize the disks as it is once DR disks are separated from prod replication and assigned to the server ?
What should be prerequisite on DR server before we can start the srdf replication (EMC) and make it work .
Thanks for All your Valuble suggestion .

Before you decide to use EMC replication give considerable thought to the fact that you are introducing a single point of failure.
Hardware snapshot replication is very fast. That is all it is. If you database crashes because of corruption on disk ... your replica will be equally corrupt.
What is fast can not do what DataGuard does ... verify quality. If the point is DR. Go with DataGuard unless EMC is willing to, in writing (not verbally) give you a guarantee (in hard cash) to cover all costs if they replicate bad blocks and it causes an outage.
And just so no one thinks I'm picking o EMC ... the same weakness exists with all of the other storage vendor's products.

Install oracle 9i rac access from both node problem

Hai,
Recently we have planned to move oracle 9i rac databases to new servers. Our current configuration is oracle 9i rac (9.2.0.4) and aix 5.3 with hacmp 5.4
mksysb backup has been taken from old machine and restored in the new machine. For oracle binarys, tar have been done and restored in the new machine.
Now after restoring the database, i am able to mount and open from the one server at a time. If i try to mount the database from second machine it is hanging. Kindly help us to solve the problem.

lmon registered with NM - instance id 1 (internal mem no 0)
After the above mentioned line, no other errors.

Oracle 10g RAC

Hi All,
I am a research student currently struggling to install Oracle 10g RAC on Windows OS.What i understand about a Oracle RAC database system is that it involves a configuration of multiple hosts or servers joined together with a clustering software and accessing the shared disk structures.What i also understand is that i need a CRS provided by Oracle for a Windows or Linux based RAC installation.
What i don't understand is for a Two node RAC system do i need a Third machine which has the shared storage device.If yes do i have to install a copy of Oracle 10g Enterprise Edition and CRS on the shared storage device moreover do i need to install a copy of Oracle 10g Enterprise edition on each of the nodes or just the clusterware is enough.

Hi Salil
No, you do not need a third machine. You can even setup RAC as a single node on one machine! What you do need is to have some sort of cluster aware file system. Try looking at OCFS on Windows in your case.
If you are interested in a Linux example please have a look at the examples at http://ocpdba.net/oracle9i_rac/cheaprac.html and http://ocpdba.net/oracle10g_rac for an OCFS implementation I am working on.

Hi all,
I have a question about Oracle RAC and network interface.
We're using Oracle 10gR2 RAC with two nodes on Linux Red Hat.
Let's assume that the public network interface goes down.
I would like to know what happens with existing connections
on node with network interface with problems.
Are connections frozen, actives?
Can the users continue to use theses existing connections using the another node of RAC?If the interface is down? what do you think? All connections to this node will die. How does your application handle fail-over, does it attempt to reconnect or just have a complete application failure?
You should spend some time in a test lab where you can test this stuff for yourself. Read the documentation and there are tons of sites out there that purport to have all of your RAC/TAF/FAN/FAF questions. - I would read and trust the documentation first.

I know that the listener goes down and any other connections is allowed.
Thank you very much!!!!

Oracle 10g RAC using ASM - Storage Issue

I’ve an issue related to Oracle 10g RAC.
I’ve 2 node cluster each being Dell 2850 Server with RHEL 4.0
I’ve EMC CX300 SAN storage with following partitions
/orasoft     10 Gb          OCFS2 File system
/oracrs          2 Gb          OCFS2 File system
/orabackup      100 Gb          OCFS2 File system
The datafiles are on ASM which is not directly visible in OS.
I’ve common Oracle Home installed in /orasoft/db_1 which is shared by both nodes in cluster.
I’ve faced an issue recently related to EMC storage.
The /orasoft partition displays 1.4 Gb space available using df command.
With both nodes sharing the common Oracle Home (/orasoft/db_1), when ever I try to touch a file I get an error as No Space left on device. I’m unable to start any service with the same reason.
Is this setup correct ??
Can anyone help me with this storage issue ??

Need a clarification here...what do you mean by "Storage System"...do you mean a server/node or the SAN storage system. If you are referring to a server/node's local storage, then it would NOT be possible for use by RAC, since the disk space has to be shared among the nodes.
Here is what you can do:
- Create two partitions/devices (for example Disk_1 and Disk_2) in the SAN storage
- Create a ASM disk group which would mirror Disk_1 to Disk_2.
Again, please note that the partitions have to be visible and be accessible read/write from both the nodes/servers.

Thanks

Hi,
If you create a new diskgroup you may be to add the same diskgroup to parameter file or spfile and which will be needing down time.
sugestion: Instead of creating new diskgroup you should to add disk to existing group.if you add asm disk to existing group your all problem will be solved and Oracle itself will be managing all.And than i am sure no need to add entry in the parameter or spfile like +db_create_file_dest=.....
