Pool Master server failover issue in Oracle VM 2.2.1

Hello All , We are new to oracle VM world. Sorry about detailed explanation.
Our current configuration is, server1-poolmaster/utility/VM server & Server2-utility/VM server
We have guest-VM running on both servers, and serverpool-VIP is configured properly. Below is our OVS-version.
#rpm -qa | grep -i ovs
oracle-logos-4.9.17-7ovs
enterprise-linux-ovs-5-1.0
ovs-release-2.2-1.0
ovs-utils-1.0-34
kernel-ovs-2.6.18-128.2.1.4.25.el5
ovs-agent-2.3-42
When we tested HA failover(shutting down server1), it work fine as expected. Pool master moved from server1 to server2, and guest VM restarted on server-2(which was running on server1 earlier).
Now-- Pool master is server2.
When we shutdown server2 now, pool master is not migrated to server1 & the guest-VMs(running on server 2) all went to power-off mode & serverpool is "inactive status'.
Found below error in server1's /var/log/messages.. It seems like some 'dead-lock situation, and the serverpool-VIP is not moved from server2 to server1, until server2 came up online". Why is it so? The expected result should be "pool-master" & serverpool-VIP should moved to server1, but it didnt.
Anyone experienced this? Any help/ input is appreciated.

You might be running into a OCFS2 bug. Check the bug list for bug 1099
http://oss.oracle.com/bugzilla/show_bug.cgi?id=1099
also related to this subject might be bug 1095 and 1080. You might want to check with the OCFS2 guys at Oracle and participate in resolving this bug. Not sure this is the case however I think this is a good starting point.
Please keep us posted.

OVM-2020 Server pool master can not be set to maintenance mode

Hi Guys.
I have 2 server in ha mode
server 1 (10.99.99.161) with oracle Manager installed (server pool master, utility server, vm server)
Server 2 (10.99.99.161) without Oracle Manager installed (utility server, vmserver)
HA enable with server1 and server 2
10.99.99.165 is the virtual server pool master
1 San connected with server 1 and server 2.
Without problem I can connect on https://10.99.99.165:4443/OVS without problem.
All seems work, but :
1 - I I try to set in maintenance mode the server 1, the VM Manager say me:
OVM-2020 Server pool master (10.99.99.162) can not be set to maintenance mode, please use server pool master failover policy to change its role, then try again.
What I shuld do ?
2 - If I turn off the server 1 the server pool master is attribuite to server 2, but I'm unable to connect on https://10.99.99.165:4443/OVS webpage. It is correct, it is a bug, or I'm doing something wrong ? Must I upgrate something ?
Many Thanks

You need to ensure the VM that's running the Oracle VM Manager software is still running. Live Migrate it first (preferred option) and flag it HA-enabled so that it is automatically restarted in the case of a server failure.

Oracle VM Server unable to communicate with pool master

Hello Forum
I have the following situation and I hope that someone has an idea/solution
Background :
Oracle VM version : 3.1
2 - Server pool
Repository : NFS
Problem :
This is the what I found out so far :
I try to start a guest which is hosted on the same on the same server , which serves as the pool master.
I don't see any progress in the OVM manager, i.e. the guest is in "Starting" status
On the ovs-agent.log file of the OVM server I see the following message keep repeating itself :
"[<Time stamp> 24944] ERROR (notification :64): Unable to send notification(111,'Connection refused')
So far I used one or both of the following work-around:
1.Rediscover the OVM server
2.Restart the ovs agent
Both work-around are feasible and successful, but I'm looking for a permanent solution.
I checked fire-wall on the OVM server and OVM master and they seem to be either down or wide-open
Any other ideas?
Thanks,
Rudi

The error messages and the server staying in starting mode in the manager are both things I've seen when a server got a new UUID.
When the agent starts, the uuid get's determined. It is possible that on-boot and on manual restart the agent gives your server a different uuid.
Try to set the uuid fixed and see if it still occurs.

Server Pool Master - 2 node HA setup - Need suggestion

I run OVM 2.2.1 in HA since 1 year.
Have 2 node. Guests failover when Utility Server,Virtual Machine Server crash.
But have problem with Server Pool Master.... ( My Server Pool Master it installed on my Node 1)
When my Server Pool Master crash, All HA guest move and restart on my second server. But because i can have only one Server Pool Master i can't graphically manage my cluster and my guest anymore.
When my primary server come back it doesn't resume it master role.
The only way to take back my console, is to restart my second server.
Note: I have a cluster URL to access to my console, however, But Oracle Express have no replication option then the BD of my second server is always empty.
What is you solution ?
How have you fix this situation ?
What the trick ?
Thanks
David

I have no answer on why your serverpool master does not resume its role when it restarts but I suggest you learn and use the XM commands on your oracle VM server to manage your guests.
To get a quick list of xm commands you can type "xm help" on your console. For more details and info run "man xm"
When your serverpool master comes back up, run the xm migrate command to move your guests from node2 to node1. When this completes, you can now reboot node2 with no issues and as I understand it, the serverpool master resumes its role after node2 is rebooted.

Set Server Pool Master to Maintenance Mode

Hi all,
when trying to set a server pool master to maintenance, I got this: "OVM-2020 Server pool master (vm-13) can not be set to maintenance mode, please use server pool master failover policy to change its role, then try again."
I have dug through the help and docs, but can not find a method for dynamically reassigning the server pool master role.
This document: http://download.oracle.com/docs/cd/E15458_01/doc.22/e15441/server.htm#CCHIEBCE , just says "You must first reassign the Server Pool Master role to another server in the server pool.", without describing how.
This document: http://download.oracle.com/docs/cd/E15458_01/doc.22/e15441/site.htm#insertedID4 , states "You can also dynamically change the Oracle VM Server which acts as the Server Pool Master without causing any outages. See Section 3.4.1, "Editing Server Pool".", which just links back to the same section I am already in.
Now, I can just migrate all my machines and then stop ovs-agent, but I am not always the one managing this, and having a nice way through the web interface would be great.
Please just tell me I am blind and point me to the section in the manuals which tells me how to do it, or is this a feature which got dropped before release?
Thanks.

I have got the same problem, I want to switch the role of the server pool master to another server in the same pool. But after reading these answers, I have absolutly no clue how to do it!
We have a productiv environment, so any ideas like shutting down or stopping VMs are not acceptable.
So here is the situation:
"ovs#1" is hosting all VMs at the moment - Server type: Utility Server,Virtual Machine Server
"ovs#2" is free of any VMs - Server type: Server Pool Master,Utility Server,Virtual Machine Server
I want to switch the Server Pool Master from "ovs#2" to "ovs#1" without any downtime. How does this work? Thanks!
Specifications:
- Oracle VM Manager 2.2.0
- Oracle VM server release 2.2.1

Non-server pool master in VM Manager

So I have two vm hosts that are not HA. The first is the Server Pool Master and everything is working well there. On the second host machine (the non-master) I put my template in the seed_pool folder and I can use xm to start the template and everything is fine, but I can not seem to get Oracle VM Manager to import the Virtual Machine Templates from the second host. Any ideas on what I did wrong?
Thanks,
Wesley

Hi Wesley,
all servers in a server pool (even if not enabled for HA) have shared repositories (this was changed with OVM 2.2, before that there was the concept of local repositories, but it does not seem to be existing anymore with OVS 2.2). These can be listed with
/opt/ovs-agent-latest/utils/repos.py -l
These are the folders the agents looks into the seed_pool to import the machines.
(note repos.py does not have an option for local repository).
If the repository is not listed here, where you put you seed_pool, then it is clear why you cannot import the template.
Regards
Sebastian

Changing the Server Pool Master

I need to remove one of the servers of a three node cluster, but before I remove that node I need to remove it as the Server Pool Master and make another node the server pool master. When I go to edit a server, the check box is there, but it’s disable. How do I enable this or accomplish this switch?

It's actually pretty simple, if both the old and new Server Pool Master servers are online. First, make sure that you're not running any VMs on either the old (existing) or new (planned) Pool Master servers. You also need to be sure that all your VMs are either Powered Off or Running, i.e. none being migrated or suspended.
Then, here are the steps:
1. Go to the Servers tab and delete the NEW Pool Master from the pool.
2. Edit the EXISTING Pool Master and replace it's details with those of the NEW Pool Master, i.e. IP Address/Hostname. If the new pool master is also a utility server, you must ensure that you select that option in the Edit screen.
3. Click OK
4. Click the Server Pool tab and select your server pool. Then click the Restore button to update the status of all your servers/VMs in the pool.
5. Manually restart the agent on the NEW Pool Master. Login to the Dom0 of the new pool master and run:
# service ovs-agent stop
# service ovs-agent start
You now have the new Server Pool Master running and the old one has actually been removed from the pool. You can add it back as a normal server using the default process in the GUI.
I know there are guys inside Oracle working on an official whitepaper on Reassigning the Server Pool Master role in situations where the old/new servers are not online, so you should keep a look out on the Virtualization OTN site.

OVM 3.0.1 : Server Pool Master Error

am starting to see sudden errors on the console. All the vm's went offline including the server icon showing RED and in status Running (Error)
The event shows : Server Pool Master Missing Event / Server Pool Master Error.
Can anyone help me how to fix this issue? This just happened all of a sudden.

Ok I found the problem...although the locking from the rescan job seemed to disappear or timeout overnight.
It was actually the virtual machine that I had under that host that was in error. All I had to do was acknowledge the event that the virtual machine was powered off (selecting the vm, going to events, then acknowledge all). It's really annoying that VM 3 has this function because you are forced to acknowledge the event before you can continue with other activities.
It would be nice if there was maybe a way to only have that enabled for specific events. Another reason that this might have happened, was that I did not have HA enabled on the VM, so it wasn't migrated to my other server when I did the reboot.

Server Pool Master fails and cannot fail over to another VM Server

Dear All,
Oracle VM 2.2.2
I have 2 VM Servers connect to Storage 6140 Array and on VM Manager I enable HA on the server pool, then on all virtual machines.
- VM Server 1 has role as Server Pool Master, Utility Server, Virtual Machine Server and has virtual machines running
- VM Server 2 has role as Utility Server, Virtual Machine Server and has virtual machines running.
I try to shutdown the VM Server 1 act as Server Pool Master but I don't see Server Pool Master fail over to another VM Server 2 and also status become to Unreachable both of 2 Servers.
Especially, All virtual machines cannot be accessible.
Please kindly give advice for this.
Thanks and regards,
Heng

Thanks Avi, I'll find and read that document. And thanks also for elaborating about the Utility Server.
After reading the followups to my original question, I tried to think of possible server "layouts" in a HA environment.
1) "N" servers in the pool, one of them is Pool Master, Utility Server AND VM Guests Server at the same time. Maybe this will be the preferred server for smaller, quicker VMs.
2) "N" servers in the pool, one is Pool Master AND Utility Server, but has no VM guests running on it
3) "N" servers in the pool, one is the Pool Master, another one is the Utility Server (none of them has VMs running on them), and finally a number of VM Guest servers
Let's take case 1. If the Pool Master & Utility server fails, given that it has VM guests running on it as well, I understand from your explanation that I'll be ANYWAY able to manually "live migrate" the guests somewhere else, using VM Manager. Is this correct?
If it's correct, then it's just a question of how much money I want to spend to have dedicated servers for different tasks, JUST FOR BETTER PERFORMANCES REASONS. Do you agree? And especially: do YOU have dedicated Pool Masters (just to figure out your "real" approach to the problem :-) )
I feel that I still miss something, the picture is not completely clear to me. The fact is, that I'm now testing on my new bladesystem, but for now I put up one single blade. Testing HA will be the next step. I was just trying to get a few things sorted out in advance, but there is still something that I'm missing, as I was saying...
Looking forward to your next reply, thanx again

Issue with Oracle MTS installation in windows server 2008

Hi Team,
Yesterday, I have installaed oracle client version 11.1.0.7, selected microsoft transaction server option and installed it in my middle tier server.
Start->program->Oracle home11g-> (Searched for oracle mts, its not available) It seems oracle client version needs ODAC to be installed (Is it correct? )
I have downloaded from oracle site. But, its throwing an error like the file is not in proper format.
1 Any special settings needs to be done for installing the MTS in windows server 2008?
2. I need to create a service in MTS to point to my database server?
3. Please share me some relative links on the same.
4. I can see MTS recovery services is running in my machine.
5. Previously, I have installed Oracle 10G client and removed it and am trying with oracle 11g. Just I have uninstalled the application and I didnt do anything. Do we need to remove anything in the registry.
This issue is very critical for me. Please share your thoughts.
Thanks and Regards,

I have the same situation. Could you please share your experience if you resolve it? Thanks.

Server Issue with Oracle and ASP Connection

We got a new server and are trying to set it up with Oracle Client to allow our web application to connect to the database server. We are getting connection errors, but on the old server, it works fine. We have Windows 2003 and IIS 6.0 on the new server and Win2K and IIS 5.0 on the old server and it's Oracle 8i. Here is the error...
Err.description=Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed.
Err.number=-2147467259
... We have the client installed, so not sure what to do from this point on. Can it be some type of a sharing issue, or network firewall issue?

Have you granted the IIS user read & execute access to the %ORACLE_HOME% directory and subdirectories?

I am not shutting down both the managed server. Only the first managed server is shut down. As the portal ear is deployed both on admin server and all the managed servers in the cluster, I should be able to access the application through the second managed server.

OVM-2008 The Server Pool Master has been registered with some other pool

I am getting this error, while creating my first ever server-pool.
Check prerequisites to create server pool (First-Pool) failed: (OVM-2008 The Server Pool Master (172.16.0.37) has been registered with some other pool, and can not register it again.)
Any idea what can be going wrong?
regards, Yora

The only time I've seen this is when the server really has been registered with another pool. You need to clean out the local ovs-agent database at */etc/ovs-agent/db* and restart the agent.

Oracle Weblogic Server 12c, issue with deploying the war created from Wavemaker tool

Hi
Recently, I am facing an issue with Oracle Web logic Server 12c, on deploying the war file (created from Wavemaker tool) to running Web logic server, it shows deployment health status is OK and web application is Active. But when I visit the home page of the application, it is unable to load the javascript files in the context and I am getting below error. Please you can check these errors in the Inspect window of the browser :
Here are the errors on hitting index page after deploying the war file to Web Logic.
http://localhost:7001/TestWarProject
http://localhost:7001/TestWarProject/lib/runtimeLoader.js 404 (Not Found) index.html:39
http://localhost:7001/TestWarProject/config.js 404 (Not Found) index.html
Uncaught ReferenceError: wm is not defined project.a.js:1
(anonymous function) project.a.js:1
Uncaught ReferenceError: wm is not defined index.html:89
(anonymous function) index.html:89
But when I exploded the war file and copy the whole application in the auto deploy folder and restart the server, it is working fine.
Can you please what is the issue not setting context path properly on deploying the war on the fly?
Has anyone found any appropriate solution or workaround? Can you please share?
Thanks in advance for helping me out.

Go to the Tomcat site and read the "First Web App" docs. I'm sure you didn't deploy your servlet properly.
