working on setting up connection between a Windows 2008 server and a pair of Oracle 11g DBs in a RAC Cluster. One Database (let's say DatabaseA) is in one data center, and the other (DatabaseB) is an a secondary, backup database. The RAC Cluster is all set up, working fine, etc. However, I Need to set up the machine.config file on my Windows Server, to go only connect to DatabaseA, unless it fails, in which case, we want it to connect to DatabaseB. Think we could do this if the host app server was Linux/Unix, but it is windows, and I just don't have the background as to the parameters to set up in the machine.config file. They are similar, but different, and we want a very specific behavior (use DatabaseA, unless fails, then DatabaseB). Application is .NET 4.0 app.
View 6 Replies View Related if it is possible to create a failover setup without RAC and DG...For example:
I have 11.2.0.2 database (with EBS 12.1.3) on dbnode1...I would like to create another node to failover my primary datbas in case of any failure.
Steps i will follow:
1: creat dbnode2
2: install same os as dbnode1
3: install same oracle as dbnode1
4: share dbnode2
database between dbnode1
and dbnode2
Now, if hardware fails on dbnode1, can i manually failover and start my database on dbnode2?
I know we can do with RAC and DG,BUT without RAC and DG If not possible..
In my production -- we have 3 nodes Primary RAC with 2 Nodes Physical secondary Standby RAC. Due to some reason we will have to failover means 3 nodes Primary Standby RAC to 2 Nodes secondary physical Standby RAC. share Steps for Failover ( not switchover) from 3 Nodes Primary RAC to 2 Nodes Physical Standby RAC. I know this is generic and can be find from google but issue is how can failover from 3 nodes primary standby rac to 2 nodes secondary physical standby rac.

What is expected behavior for VIP on Linux servers? ( 2-node RAC)
1.When entire RAC stack is running, and one node is rebooted or crashed? Will VIP fail over to second node?
2.When one node RAC stack is contained (crsctl stop crs), shutting down RAC stack on remaining node? What happens to the VIP and Scan IP?
3.When RAC stacks are down on both nodes, one node has VIP on (eth0:1), reboot this node. What happens to the VIP?
We see some behavior in scenario 3, but don't know why the VIP was moved to second node as all Oracle processes are down.
Are Oracle cluster and Oracle clusterware are same and has same in meaning in RAC ?

My trouble is that with this configuration, access it randomly BASE1 or DGBASE1 but DGBASE1 is not available for users then I have failure

I can see that some failover events etc aren't supported (Differences between the ODP.NET Managed Driver and Unmanaged Driver), but is failover supported at all? I don't need to get notified, just to get the failover (clustered node switching) working. Is it supported in the managed driver?

Yesterday I was installing 11.2.0.2 patch to our Oracle 11gR2(11.2.0.1.0) Two node RAC cluster on OEL 5.4 x86 Linux.Before installing I have read [URL] support note which says "Note: All Oracle Grid Infrastructure patch set upgrades must be out-of-place upgrades, in which you install the patch set into a new Grid home. In-place patch set upgrades are not supported. "
During Installation I found following Installation Option :
1) Install and configure Oracle grid Infrastructure for a cluster
2) Configure Oracle Grid Infrastructure for a Standalone Server
3) Upgrade Oracle Grid Infrastructure or Oracle Automatic Storage Management
4) Install Oracle Grid Infrastructure Software Only
Which option should I have to choose here ?
we had our Oracle RAC database at primary and Standby database as DR. It was running in 10g (10.2.0.1.0) in HP UX 11i platform.
We need to upgrade both the setups from 10.2.0.1.0 to 10.2.0.4.0 . I will go through the upgrade guide, i like to know is there any special case for upgrading when we do for both primary and standby database.
And whether i need to create a new Oracle home with 10.2.0.4.0 software or i can upgrade in the same oracle home which already exists.

CentOS 6.4 64bits Oracle......: 11.2.0.4 64bits
I am running some small tests here in my test env, using dataguard. I have configured the Primary and Standby with Maximum Availability... they're running just fine. Now i want to execute a failover test (i have already ran a Switchover test with the Broker successfully).
My question is very simple, at my point of view: What are the required steps to execute a successful manual failover? For example, i have my env as follows:
- Primary: prim1
- Standby: stdb1
Suppose that the primary database crashes in an unrecoverable way... is this case a manual failover would be necessary.
To do so, i would have to execute the following command, in my Standby database:
-- stdb1 is the standby database... DGMGRL> failover to stdb1
The above command is correct? Are there any required configurations after the failover? I read the Oracle Docs, and it says

After that during the installation process of the Grid it failed at step "Configure Oracle Grid Infrastructure for a cluster". After it failed at this step, subsequent steps too failed which I asked OUI to ignore and then I ran both the post installation scripts. And then ran post crsinst which failed.
