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-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.

  • 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

  • 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

    What I shuld do ?You need to live migrate all your guests off the current Master server, then issue service ovs-agent stop on the command-line. This will cause the pool mastery to switch to another server. Once that's done, you can start the agent agent.

    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.

  • 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

  • OVM-4602 HVM is not supported in the server pool

    Hi,
    I'm trying to create a Windows 2008 R2 HVM guest and have come across this error:
    "OVM-4602 HVM is not supported in the server pool"
    Hardware is a HP BL25p G2 with AMD-V enabled in the BIOS. This is 1 of 5 similar servers in the server pool - all 5 servers have AMD-V anbled in BIOS. I checked the following:
    xm info | grep xen_caps:
    xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64
    xm dmesg | grep -i hvm:
    (XEN) HVM: SVM enabled
    cat /proc/cpuinfo | grep svm:
    svm is not listed in the flags
    I'm creating the guest from VM Manager using an iso file. I haven't tried using virt install yet as I would like to get some opinions here first.
    Thanks in advance.

    I know 3 of them were enabled after installation of OVM due to an oversight but can't vouch for the other 2 servers (these 2 were the first servers installed with OVM, including the master server).Remove and re-add them back to the pool. Oracle VM only stores the hvm-capable flag when it adds the server initially. It doesn't re-evaluate this later.

  • How to change the connection pool configuration on OC4J?

    Hi everybody,
    I am developing an application with JDeveloper which is running on an OC4J standalone server, we have 2 enviroments, the develop server and the server of the client, and the data base connection configurations are differents.
    The problem is that if we try to deploy the application (we have deploy on the develop server) on the client server and try to change the connection pool configuration the application cannot connect to the data base, we need to re-build the project with the client connection pool configuration.
    We tried to change the configuration on the enterprise manager of the OC4J, on "JDBC Resources" panel, and the test the connection is ok, but when try to access to the application we get an Exception. After that we try to do that changing the parameters from the datasources.xml file on the application, but the result is the same.
    How can we change the DataBase configuration without re-build the project?
    Thanks very much
    Tony

    Meaning you have created just the empty data-sources.xml and not configured any Connection Pool and DataSource in JDev?
    In Oracle AS 10.1.3 you have two ways to do this:
    1. Use JDev and configure the data-sources.xml (Context Menu -> Properties)
    2. In Oracle AS: Select application -> Administration -> Services -> JDBC Resources -> Create Pool and Create DataSource

  • 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 - 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.

  • 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

  • I changed ISPs and had to change the server settings. Now one of my two email addresses crashes every time I try to read the emails.

    At first Thunderbird downloaded every email from the problem account going back to 2011. I changed the server settings to only download emails from the last 15 days and to delete any messages older than 15 days.
    I can send emails from this account and my other email account works fine for sending and reading mail. However, this problem account crashes Thunderbird every time I try to read the messages. There are now only 300 messages in the inbox and I've been able to have them marked as read. But I still can't read any of them.
    What's the fix on this?

    Try to start *Windows* in safe mode with networking enabled.
    - Win8 http://windows.microsoft.com/en-US/windows-8/windows-startup-settings-including-safe-mode
    - Win7 http://windows.microsoft.com/en-US/windows7/Start-your-computer-in-safe-mode
    - XP http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/boot_failsafe.mspx
    Still in Windows safe mode, start Thunderbird in safe mode.

    Does the problem go away?

  • Not getting the server pool in the list of server pool

    We are facing following issue. Can you please help on this. Or how can we get help on this. I would be thankful for this.
    We have created a server pool which consists of two vm servers. Two vm servers we created manually.
    We are using following steps to create third virtual server.
    1. Click "next" on "create virtual machine" screen.
    2. Click "next" on "installation media" screen
    3. It asks to select a server pool from the list but we are not getting the server pool in the list of server pool which we created earlier.
    We did this exercise before and we got the server pool name in the list which allowed us to create virtual machine. Now when we reinstalled the vm servers machine and also vm manager, we are not able to do this once again.

    Hi,
    please check the status in Server Pools ( it need to be in Active). then check in the Servers the status need to be in active in VM Manager.
