Greetings,
I have two nodes that I want to cluster using VCS in order for an application to have high availability, it is a JAVA application running on JBOSS (JBoss clustering was not helpful) and having an Oracle DB as backend.
I downloaded VRTS_SF_HA_Solutions_6.1_RHEL.tar.gz and installed the VCS product on both nodes though a 3rd host (let's call it balancer). Now what?
node1: 10.172.21.144
node2: 10.172.21.164
I understand that there is VOM on each node (I got that info after VCS installation was finished) and I think it's the tool to manage the cluster, but how should I use it? shouldn't it be on a 3rd host or something in order to manage both nodes? I tried accessing it from node1 such as https://10.172.21.144:5634/admin/htdocs/cs_config.htm - I tried to go on with the wizard here to configure it, but it failed with "VRTSsfmcs package is not installed" after keeping the defaults. I checked the VRTS on node1, and there was no VRTSsfmcs installed, I also didn't find it in the main installer (when running it on balance the first time). What can I do here? and what is VRTSsfmcs anyway?
Another thing, during the installation, I added a virtual ip. The virtual ip was configured on node1 on eth1 as an alias as I see it. Isn't the virtual ip, an IP used for reaching and load balancing the two nodes? why is it configured on eth1:0 on node1 only? I didn't see it on node2. Or does VCS magically reconfigure it on node2 if node1 is down?
I understand that the virtual ip is the ip to use when dealing with the application that should be installed on both nodes. Am I right here?
Note: I am testing VCS on two VMs (node1 and node2) with each having two bridged NICs (for testing fencing too), and balancer here is also a VM. All on RHEL 6.4 64bit.
Any help is appreciated
Regards
