Migrating between server pools

Is it possible to move a vm between server pools? Im am trying move a clone vm from one server pool to another server pool...
Im getting the following error: Server Pool: ServerPool has no compatible servers for the clone of ....
Any resaon why i mite be getting that error?
Is it possible to present a repository to multiple server pools?

Exactly how are you trying to do this. Are you choosing to clone and then running the clone customizer to map your storage and vnics?

Moving shared storage repository between server pools

Is there a way to move a fiberchannel storage repository between server pools? The documentation says its possible only with NFS, but we are moving to new server pool and for this we need to be able to take a loaded SR and remove it from one server pool and discover and use it on another pool?

How to Migrate VM Server pool to Other Oracle VM Manager

Hi,
I want to move oracle server pool from One Oracle VM Manager to other VM manager.
Can any one help me on how to migrate vm server pool to other VM Manager.
Thanks & Regards
YJR

Hi,
unfortunately I don't know of an easy supported way.
The process itself is pretty similar to migrating serverpools to Enterprise Manager as described in this note:
Migrating from Oracle VM Manager to Enterprise Manager Grid Control (Doc ID 807091.1)
With the exception that you simply register the new pool in a new manager and then have to rediscover all VMs.
So overall it is a simple "delete serverpool" and "create serverpool" with additional import of virtual machines.
If during this steps a problem arise, you still can deconfigure everything and reregister with the new manager (with the help of cleanup.py).

Service Profiles Migration between Server M2 and M3

Hi Cisco Top Guns!!!
I have tried to migrate some service profiles between servers M2 (with M81KR) to M3 (with Vic 1240 and Vic 1280) and Windows 2008 R2 recognized the interfaces on M3 as new interfaces.
The ghost devices interfaces (old interfaces) still presents on Windows and to rename the new interfaces or apply the same IP configurations, I need to remove the ghosts interrfaces.
On my opinion, this change goes against the UCS philosophy.
I have a case opened with Cisco Developed Team and now Im sharing this issue with the community. Anyone have benn passed for this problem too?
Regards,
Fábio Henrique Teixeira - System ITS

This is a hardware change to the operating system. While UCSM can abstract the MAC/WWPN/WWNN information, the operating system recognizes a hardware adapter difference and will instatiate new devices. This is an OS issue. Some OS's (Linux) will allow you to set a flag to ignore the hardware change. I'm not aware of whether and what versions of Windows that will allow the same behavor. We cannot modfy the hardware identification change, as we use it within UCSM to manage allowable firmware bundles and adapter polices (vnics/vhbas/fabric failover)

OVM 3.0.3: Create new Server Pool but keep storage repositories?

Hi,
I think I have somewhat messed up my Server pool a bit, such as that there are some kind of network bridges in the server pool which I cannot get rid of, since OVMM insists that these have vnics associated to them, when none of my VMs had any nic configured.
So, I guess my only option is to re-create the server pool entirely and migrating VMs between server pools doesn't seem to be possible. I was wondering, I if could at least keep the storage repositories and get away with only creating a new server pool and adding the VM servers to the new pool, but keeping the VM files in the repositories. This will likely make this transition much more smooth, than having to copy all the VMs from the repositories onto a temporary storage and back into the new storage repositories.
Cheers,
budy

Check the network configuration of the templates installed into your repositories and change the bridges to real/proper ones. Once you've done that, you'll be able to delete the unusued bridges.

It's possible to change this, but you need to contact Oracle Support to do so. I'd recommend first trying to unmap the existing bridges as described above.

Server 2012 R2 Hyper-V Cluster, VM blue screens after migration between nodes.

I currently have a two node Server 2012 R2 Hyper-v Cluster (fully patched) with a Windows Server 2012 R2 Iscsi target.
The VMs run fine all day long, but when I try to do a live/quick migration the VM blue screens after about 20 minutes. The blue reports back about a “Critical_Structure_Corruption”.
I’m being to think it might be down to CPU, as one system has an E-2640v2 and the other one has an E5-2670v3. Should I be able to migrate between these two systems with these type of CPU?
Tim

Sorry Tim, is that all 50 blue screen if live migrated?
Are they all on the latest integration services? Does a cluster validation complete successfully? Are the hosts patched to the same level?
The fact that if you power them off then migrate them and they boot fine, does point to a processor incompatibility and the memory BIN file is not accepted on the new host.
Bit of a long shot but the only other thing I can think of off the top of my head if the compatibility option is checked, is checking the location of the BIN file when the VM is running to make sure its in the same place as the VHD\VHDX in the
CSV storage where the VM is located and not on the local host somewhere like C:\program data\.... that is stopping it being migrated to the new host when the VM is live migrated.

Mixing CPU models in same server pool in OVM 3

How contained is Live Migration when it comes to CPU model?
For example, if I have a 6 Core opteron system, (8439 SE) CPU that shows "Default_AMD_Family:16_Model:8_NoNx" in OVMM, what part of that needs to match to be compatible with another server with a different processor?
We want to mix 8439 SE (6 core) processor systems in a pool with 6176 SE (12 core) systems, how can I tell if those processors would support Live migration between the two?
Thanks,
Dave

By chance do you know how the behavior of a server pool with mis-matched pairs of servers acts? I know you can add them to the same pool, but is OVM 3 smart enough to make sure guests that were originally started on one server, only start on that kind of server in the future? For example, I dont want a server provisioned on an Intel CPU to reboot to an AMD cpu.Why not? Booting is easy and a guest that boots on Intel today will happily boot on AMD tomorrow. it's only live migration that's restricted. Everything else is fair game, assuming the storage and networking is identical across all the machines.

Difference between connection pooling and simple connection

Anybody please tell me what is the Difference between connection pooling and simple connection and also where we define connection pooling and how.
Thanks
Please reply soon
amitindia

Creating and closing connection to the database is a relatively slow process. Equally connections use database resources so you can't just open as many as you want.
A connection pool maintains a number of open connections throughout the lifetime of the application. Instead of opening and closing the connections your application just "borrows" them from the pool when they're needed.
If the pool runs out of connections it will usually create new ones as needed until you reach some predefined upper limit.
A good connection pool will also manage connections which have failed for any reason, and report code which fails to return connections to the pool (ie connection leaks).
The number of connections created at startup is referred to as the "low water mark" and the maximum number that the pool will allow to be opened at any given time is the "high water mark". If no connections are available client code will generally block until one is released.
If by "defined" you mean where can you get a working implementation then your database or application server vendor is likely to provide one. Also the Apache Jakarta Commons includes [url http://jakarta.apache.org/commons/dbcp/]an implementation which you can use with any JDBC driver.

Server 2012 - Problem with multiple instances of RDS looking to the same license server. Server Pools requiring the wrong servers.

Hi All,
I have two domains, prod.local and test.local. On prod.local, I have a license server living on the connection broker. I have created a two way trust between the domains so that the RDS instance on test.local can use the license server on prod.local.
When I first setup the RDS instance on test.local and point it to use the license server on prod.local everything appears to work, all servers recognize the license server.
However when I log off and back on, and click the RDS dashboard in test.local, the Remote Desktop Services overview states I need to add every server from prod.local to the server pool. This is bothersome because the Remote Desktop Services on test.local
is still functioning, but I am no longer able to manage it. When I add the servers from prod.local to the server pool I am displayed the setup for prod.local instead of test.local
Is there a way around this? Can I use the same RDS license server key multiple times?
tldr: Using a different domain's license server causes my RDS instance in Server Manager to display the wrong RDS farm.

Hi Nathan,
Thank you for posting in Windows Server forum.
Please check the required ports must be opened on firewall.
- To issue RDS Per User CALs to users in other domains, there must be a two-way trust between the domains, and the license server must be a member of the Terminal Server License Servers group in those domains.
- To restrict the issuance of RDS CALs, you can add RDS Host Servers into Terminal Server Computers group on RDS Licensing servers.
- Configure RDS licensing server on all RDS Host Servers in each domain/forest. You can do it through RDS host configuration snap-in or through a group policy.
- Add administrators group of each domain/forest in the local administrators of RDS licensing server. This way, you’ll not get a prompt to enter your credentials when you’ll open RDS host configuration snap-ins in trusted domains/forests.

How to start virtual OVM Manager and restore server pool which hosts it?

It had to happen... the day I migrate our OVM Manager from an ESX host into an Oracle VM, we have a massive NetApp outage, and everything fails to come back. As a result of having lock errors when trying to start any VMs I noted on the forum various solutions and ended up following the steps concerning stopping ovs-agent and removal of /etc/ovs-agent/db/* on all the servers. Next I re-added the repo to all the servers using repos.py, but of course now none of the servers are in a pool so the --list command shows them as [R] rather than [*], and the /OVS directory is not yet mapped. So the next stage, according to the instructions which I am following, describes using the 'Restore' option in the OVM Manager GUI. Given that /OVS is not mounted and all of the servers are now config-less, I can't see how I can start the OVM Manager VM to get to the aforementioned "restore" option...
Thank Jeebus I kept the ESX copy of OVM manager on (but powered down), as I was able to fire it up and do the restore, and now everything is hunky dory. However, this is our Dev platform and I was going to build the Prod platform and deploy OVM Manager straight into the OVM architecture via the template, rather than having it on ESX, but this issue on the Dev install has made me think twice about the mobius nature of managing the VM architecture from within the VM architecture...
I am assuming I am missing some sort of commandline knowledge, so... given:
- empty db directory
- root repos [R] on all servers
- as yet unmapped /OVS
...how to get the server pool up and get something back into /OVS, and then start my OVM Manager VM so I can 'restore'? Is it even possible? because if it isn't, I'll be blowed if the Prod OVM manager is going to get deployed like this...
And no, there's no money in the budget for extra tin just to sit there running the OVM Manager and nothing else.
TIA
Kev

Still nobody seems to know of how to create a server pool on the CLI (outside of OVM Manager) though...There is no way to create a server pool on the CLI without Oracle VM Manager. You either need to use the Web UI of the Manager, or use the ovmcli command-line tool. Both of those require Oracle VM Manager to be running.
However, once the Pool is created, you do not need the Manager to be running to perform simple tasks like starting/stopping guests. That can be done with the xm command-line tool.
I agree with you about running VM Manager as a guest of the Oracle VM Server: I actually don't recommend this in production, unless you have at least two Server Pools. Then you can have the Manager of Pool A hosted by Pool B and vice-versa. Most often however, I recommend a completely independent Manager machine, either physical or hosted on a separate virtualization stack.

How to migrate File server to NAS device?

All right so here's the scenario.
An external forest level trust is setup between two forests A & B as recently as we acquired the company B.
Users from forest B were already migrated to domain A.
Now I need to migrate file server from domain B to my domain A but the target where we need to move file shares is a NAS device, so basically we cannot do a simple server migration from domain B to domain A.
We need to copy over the data+ACL+Share permissions from fileserver in domain B to a NAS device in domain A whereas of course ACL permissions on file server present in domain B will obviously be as per source domain user accounts, example ACL permissions
currently will show as "B\user1".
So whats the best way to perform this in order to maintain the permissions & data.
Another question how do we copy share permissions from file server to NAS as I can robocopy the data with security permissions but how to copy over all the share permissions to destination NAS?

Hi,
You need to retain the SID History attribute when users across domains to ensure users in the target domain can access to files during migration.

Migrating Virtual Machine - Error "Failed to Complete planned Virtual Machine at migration destination" - Server 2012 R2

So to get started I'll give a bit of background on the Infrastructure we are currently working with.
We have:
2 x Hyper-V Hosts (Currently 2 for testing migrations, this will increase once we have a working platform)
2 x File Servers acting as storage nodes for VHD Storage
1 x Physical DC
The Hyper-V Hosts both have Server 2012 R2 Datacentre installed, the rest have Server 2012 R2 Standard installed and configured.
We currently have some VM's sitting on one host and I am in the process of simulations to make sure live migration is working between the two HV Hosts (This is a non-clustered setup), Everything is on the domain and i've been using a domain admin account
to administer these servers for these simulations.
We plan on having VHD's stored on FS01 and FS02, basically our primary host is going to have all primary servers on and then those vhd's will be stored on FS01 and then all secondary/redundant servers are going to be on the second host and vhd's stored on
FS02 - Simple enough?
I can perform Data migrations between both FS01 and FS02 using the Hyper-V Management tool on both hosts without any issues. The issue I am currently encountering is when I perform a migration of the "Virtual Machine Only". Now, this simulation
works when the data for the VM is stored on either of the hosts using UNC pathway, no hiccups at all, I receive the below error when ever the data is stored on either FS01 or FS02 using again, UNC pathway (These VM's power on and work perfectly otherwise while
hosted on FS01/02).
Error:
I've researched this quite a lot and have gone through countless solutions other people are having.
http://social.technet.microsoft.com/Forums/windowsserver/en-US/5780d041-4036-404e-9f33-8abe025bfe2b/hyperv-failed-to-create-external-configuration-store-general-access-denied-error-ox80070005?forum=winserverhyperv (Which
took me to the below link)
http://support2.microsoft.com/kb/2249906 (This solution didn't work, in fact i couldn't even get CMD to run the command)
Now, with
THIS SOLUTION that I attempted I worked with adding all the hosts and FS01 (because nothing is on FS02 at the moment) in an attempt to get the VM Migration only working between hosts and still receive the same error.
As a testing option, I Moved the Data for the VM back to one of the hosts using UNC pathway and then performed a live migration to the other host no problems, then performed a data migration back to FS01 and that also worked. I don't particularly want to
do this with production VM's as I have at least 6 x 780GB vhd's that need to be moved and this would move them more than once, obviously not ideal.
If someone is able to help me out, or at least point me in the right direction, that would be awesome!

I did try adding the 'Everyone' permission for the testing of migration to see if it was a permission issue which didn't help at all before I'd posted this article.
This ended up being a Computer Delegation issue, I'd neglected to add the 'cifs' (SMB Protocol) on ALL servers for ALL servers in the cluster, I didn't add that permission in my FS01 or FS02 servers for each other or the hyper-v servers that were in operation.
I've now started our production Hyper-V Servers and they haven't skipped a beat since adding in those delegations correctly to all servers as a "Full mesh" type setup.
Thanks for responding in any case :)
This is the permission I am referring to if anyone else has the issue:
AD>Computers>{Name of Computer}
I also performed an active directory replication forcefully with:
repadmin /replicate <Target> <Source> dc=Domain,dc=local
Run as a powershell command.

Difference between interface pool and class pool

Hi,
Can any body tell me the difference between Interface pool and Class pool.
thank you in advance.
regards

Hi,
Class and Interface Pools
This section discusses the structure and special features of class and interface pools for global classes.
Global Classes and Interfaces
Classes and interfaces are object types. You can define them either globally in the Repository or locally in an ABAP program. If you define classes and interfaces globally, special ABAP programs called class pools or interface pools of type K or J serve as containers for the respective classes and interfaces. Each class or interface pool contains the definition of a single class or interface. The programs are automatically generated by the Class Builder when you create a class or interface.
A class pool is comparable to a module pool or function group. It contains both declarative and executable ABAP statements, but cannot be started on its own. The runtime system can create runtime instances (objects) through a request using the CREATE OBJECT statement. These objects execute the statements of the class pool.
Interface pools do not contain any executable statements. Instead, they are used as containers for interface definitions. When you implement an interface in a class, the interface definition is implicitly included in the class definition.
Structure of a Class Pool
Class pools are structured as follows:
Class pools contain a definition part for type declarations, and the declaration and implementation parts of the class.
Differences From Other ABAP Programs
Class pools are different from other ABAP programs for the following reasons:
·        ABAP programs such as executable programs, module pools, or function modules, usually have a declaration part in which the global data for the program is defined. This data is visible in all of the processing blocks in the program. Class pools, on the other hand, have a definition part in which you can define data and object types, but no data objects or field symbols. The types that you define in a class pool are only visible in the implementation part of the global class.
·        The only processing blocks that you can use are the declaration part and implementation part of the global class. The implementation part may only implement the methods declared in the global class. You cannot use any of the other ABAP processing blocks (dialog modules, event blocks, subroutines, function modules).
·        The processing blocks of class pools are not controlled by the ABAP runtime environment. No events occur, and you cannot call any dialog modules or procedures. Class pools serve exclusively for class programming. You can only access the data and functions of a class using its interface.
·        Since events and dialog modules are not permitted in classes, you cannot process screens in classes. You cannot program lists and selection screens in classes, since they cannot react to the appropriate events. It is intended to make screens available in classes. Instead of dialog modules, it will be possible to call methods of the class from the screen flow logic.
Local Classes in Class Pools
The classes and interfaces that you define in the definition part of a class pool are not visible externally. Within the class pool, they have a similar function to local classes and interfaces in other ABAP programs. Local classes can only be instantiated in the methods of the global class. Since subroutines are not allowed in class pools, local classes are the only possible modularization unit in global classes. Local classes have roughly the same function for global classes as subroutines in function groups, but with the significant exception that they are not visible externally
Reward points if useful....

Not able to add a server into server pool

We are managing VM setup consisting 2 VM server with Network range 10.180.10.X Series.
To meet security guide We have to change DOM0 IP range from DOMU Which is 10.180.20.X.
So we have added a new VM Server (The move was done to make sure no downtime is needed by using live migrate option).
The new Server of Network range 10.180.20.X is added to server pool.
But i m unable to migrate the vm machine to newly created server.
It has also observed that no storage repositories are added even after initializing the repositories.
(I had to manually mount the repositories(NFS) and then add them using
/opt/ovs-agent-latest/utils/repos.py -n
/opt/ovs-agent-latest/utils/repos.py -r
/opt/ovs-agent-latest/utils/repos.py -i
We are using OVM 2.2.1.

Hi Roshan,
Change the properties like this and try:
cardinality : 0..n
collectionType : list
selection 0..n
singleton true
typedAccessRequired true.
Your problem is to add the elements to this node, I guess you are taking input from the table UI element. Then you must create elements to this node.
IPrivate<viewname>.I<nodename>node node = wdContext.node<nodename>();
for(int i=0; *i<10* ; i++)
IPrivate<viewname>.I<nodename>Element ele = node.create<nodename>Element();
//If you want you can set you attributes here
node.addElement(ele);
10 elements are created.
You can create & add elements like this.

Siva

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.
