We have 2 servers running Oracle 11gR2 Window server 2008 64 bit RAC. Today I add new shared disk visible from both servers. All our data placed on ASM partitions, but we need Windows volume for exchanging some data between servers & users;Actions:then i have prepare disk on shared storage from 1st node, run diskmfmt.msc & rescan disks when windows recognizes new hdd, initialize it.create an Extended partition & Logical drive & Assign drive letter. from another nodes, make sure no drive letter is assigned.
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.
I am using newstart cluster software. currently I have two blade servers in my system and I have configured cluster as well. right now I have one issue. I am using the ip address of 10.34.14.0/28 network for cluster but this can not be accessed from all network so I want to use different range of IP of 10.68.1.0/28 network in the same blade servers. Can I configure two different floating (cluster) IP? the first IP range is for signalling and second IP range 10.68.1.0/28 network is for OMM. I need to use both IP in two blade servers.
View 1 Replies View RelatedI'm a long time Oracle DBA but have only recently started with RAC and have never done any patching or upgrades in a RAC environment.
My environment consists of a 2 node RAC cluster, and 2 physical standbys at separate remote locations.
The database, GI, ASM, and clusterware are all at version 11.2.0.1.
I want to upgrade all components to the latest patchset which is 11.2.0.3. Eventually I also want to apply the latest PSU.
Can I do this without down time? It is a mission critical database where downtime could conceivably endanger lives. If it can't be done with zero downtime, then downtime must be kept to an absolute minimum (minutes, not hours).
I suspect the clusterware needs to be patched first and I do not know whether I can do it on one node at a time.
I am running oracle linux 5.7 on VMware Workstation 9 and trying to install Grid 11gr2, during installation my system freezes and I see out of memory errors.

I have been asked to look at making an existing Oracle server resilant. The technology I need to use are:
- Windows 2008 R2 Enterprise SP2
- Microsoft Cluster Services
- Oracle Enterprise 11g release 2
- Oracle Fail-Safe (latest version available)
Unfortunately ApEX 4.1 and Mod_plsql are install on the existing stand-alone server. I'm afraid i know very little about Oracle and ApEX but i need to make a design decision and check fiesablilty.
I believe the HTTP service and Mod_plsql can be moved to a independant server which should work but ApEX itself must remian on the database server (i'm told).Will ApEX work in a MSCS setup? I can only find references to RAC support, RAC is out of scope.
current environment
Oracle VM 2 Node RAC cluster
Oracle 11G 11.2.0.3.0
Oracle 11g rel 2 GI
on current 2 node cluster we have GI and RAC db configured Nodes: vmorarac1,vmorarac2
we shutdown vmorarac1 to clone it to vmorarac5
on new node I have changed the hostname to vmorarac5 In /etc/sysconfig/network-scripts/ifcfg-eth0 change ip to new ip and same for /etc/sysconfig/network-scripts/ifcfg-eth1 152.144.199.210,152.144.199.211
mad echanges to /etc/hosts on vmorarac1/2 for 2 new IP address assigned to vmorarac5

hostname change in /etc/sysconfig/network
On new node vmorarac5, there is alreay software for RAC DB and GUI cloned from vmorarac1
addnode.sh is used to add existing node, but as part of pre-requisite configuratoin is there any config step missing
I have a RAC working with SAN raw devices presented to ASM and working fine. My situation has changed since the installation of the RAC. Now I need a shared storage (with a filesystem) to upload some files (so DB can read these as external tables) for this I have used OCFS2.
As you can see I have Oracle RAC on raw ASM + shared storage on OCFS2 and for the time been all seems to be well and working perfectly. Can these coexist with out effecting the other?
I would like to build a 2-node cluster without RAC. I desire to operate 2 Oracle database instances for use by 2 separate applications. I plan to run Linux. I would like node1 to act as the primary server for the databases in application1 and node2 to act as the failover server for the databases in application1. Conversely, I want node2 to act as the primary server for databases in application2 and node1 to act as the failover server for databases in application2. Can Oracle SE and Oracle Clusterware be configured in this this way?

My application consists of Oracle RAC and Oracle Enterprise Manage (OEM) on same two nodes. I am exploring the idea of utilizing Oracle Clusterware (which is already installed with Oracle RAC) to support OEM in active passive mode.
Here is the scenario.
Node A running Solaris 10.9 on SPARC and Node B running Solaris 10.9 on SPARC.
Node A and Node B are both Oracle RAC Nodes ( Active Active ) which use Shared Storage for Oracle using ASM.
Node A and Node B will run Oracle Enterprise Manager (OEM) Application in active passive scenario which will be using Oracle RAC for its database. So, both Oracle RAC and OEM are sharing same server A and B for its clusters.
Now, OEM application need a third party clusterware to fail it over. It needs clusterware to provide floating VIP and shared folder of the size of 20GB which will keep software libraries. If node A goes down, node B have access to same libraries and will come up as active.
Do you know if oracle clusterware which comes with Oracle RAC can support OEM for failing over i.e. it can provide floating VIP and shared file system?

I need some professional article about how to configure DNS for using Oracle GNS with explanation.
I want to understand the role of DNS server for GNS.
I tried to search but what I found is not enough or they are not written with accuracy.
Here we are going to configure a new set up on new hardware :
clients requirements :
oracle 11g with ASM :
Number of instance = Single database
Platform = IBM AIX 6.1
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?
