I want to install an active / passive Oracle Configuration for our new 11gR2 system. We do not want to go full blown RAC as yet. We already have an 11gR2 instance that I plan to CLONE to the production server(s).
So. detail the steps that I need to follow .
i.e.
configure the 2 servers (VIFs/Interconnects)
Install GRID/CRS
Clone over the database (do I do this as a SINGLE NODE RAC?)
I have to manage an active passive cluster on SLES10 SP4. Oracle 10.2.0.4. All oracle binaries are on a DRBD Device on mountpoint /oradata. This mountpoint includes the binaries and all datafiles.
I havent installed these systems. At one stage on node died and got reinstalled by a system administrator. After a switch from the running node to the standby node, the cluster is not starting.
Jan 3 14:36:01 a logger: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.6114.
Jan 3 14:36:14 a logger: Waiting for Oracle CSS service to be available before starting
Jan 3 14:36:14 a logger: ASM instance +ASM. Wait 2.
After issuing $ORACLE_HOME/bin/localconfig add the cluster is starting, the asm instance is coming up, and also the database instance is starting.
Shortly after that the db instance dies. Alert log is showing something like recursive sql error. Looks like writing to the datafiles is not working. In asmcmd the diskgroups are showing DISMOUNTED (show MOUNTED before)
so what to do ?
a) Why is it necessary to issue "localconfig add" to make the cluster starting ?
b) What could be a reason for not being able to write to the database ?
c) How to install an active/passive cluster ?
c1) Install OS on both nodes
c2) Install oracle binaries
c2.1) on both nodes in the local files system and do the mapping to the drbd afterwards?
c2.2) only on one node and just switch the mountpoint ?
I am installing RAC 11GR2 in VMWARE on OEL 6.3. Everything went smooth but when i tried to configure ASM , I get below messages.

I am having 2 data centers within 1/2 km distance. And we kept each vote disk in once site. In case of site failure, the cluster needs a 3rd set. We don't have 3rd site.
Last open world, Oracle announced that oracle storage on cloud as announced. If I get the small space on the cloud, can i put my 3rd vote disk on the cloud?

I have been reading a lot of documentation regarding oracle services and I have an ok understanding of how they work. However, I have a general question regarding configuring services using Oracle RAC. For instance, if I have a 2 node oracle 11GR2 RAC on a Linux Redhat server. I have an application that connects to a service I have created. I create the service as follows.
srvctl add service -d ORCL_RAC -s APP_SERVICE -r ORCL_RAC1,ORCL_RAC2
The tnsnames contains:
APP_OLTP =
(DESCRIPTION =
(LOAD_BALANCE = ON)
(FAILOVER = ON)
[code]...
My questions are as follows:
1) When I do a 'srvctl status service -d ORCL_RAC', should I see the service running on both nodes of the RAC? Or does it run only one node, then it will fail over to the other when needed?
2) If I have a RAC environment where I see two services created (RAC_SRV1 and RAC_SRV2). I see that RAC_SRV1 is only running on node1 and RAC_SRV2 is only running on node2. There are two applications sharing the same database, one application is using RAC_SRV1 and the other application is using RAC_SRV2. Am I correct in thinking that there is no failover available here? If node1 goes down, the application connecting to RAC_SRV1 will not be able to connect to node2 right?
3) In the case of the scenario in question 2 above, would it be best practise to simply create one service and have both applications connecting to the one service? Could I configure the one service to point connections from one application to node1 and connections from the other application to node2?
We are in process of upgrading 10g (RAC) database to 11g(RAC), does the oracle client software must also be upgraded to 11g or the 10g client can be used for 11g database connectivity, since there are thousands of end users it is very difficult to upgrade all the clients.What is the best approach for client software?

In our current setup we have RAC on standard edition and client is now planning to go for Enterprise Edition but not yet decide because of cost. Is there any difference between Grid Infrastructure 11gR3 Enterprise edition and Standard Edition ?
They told me to first install Enterprise Edition and then will move to Standard Edition if they can't get the EE license so in that case do i have to re-install Grid infrastructure for standard edition?

Just want to know if there will be a difference at all in these 2 methods.2)What is the best way to migrate the data in the database, datapump or rman (rman takes full backup in the present "live" so this can be moved to "new live" and can be recovered)? What would be the method with least downtime?(Once the data is transferred, the database in the "old server"will be deleted)3)The structure of the data files (folder path) are going to be different in the old and new servers, so I have to precreate the tablespaces, so will the impdp fail in this case?

We have 2 servers running Oracle 11gR2 Window server 2008 64 bit RAC. Today I add new shared disk visible from both servers.

Sometimes Windows automatically assign drive letter. If drive letter is assigned, right click & Change drive letter & Remove. from 1st node, format this logical drive using ocfsFormat.exe after execute below scripts i have face some issues

This indicates that the Cluster Name has not been configured on this node for OCFSThe volume formatted in this condition will be seen by all nodes running OCFS.
