Hyper-V Replication Implementation question

I have two Hyper-V 2012 servers. I want to setup replication between them but I wanted to clarify a few things. My plan is to put 3 VM's on each Hyper-v Server and then replicate them to the other servers. So Server A has 3 VM's and Server B has
3 VM's. In case of a server failure the servers on Server A will failover to Server B and vice versa. This also applies to the VHD's. I want everything to replicate between the two. And I need to make sure that the process is automatic so if storage fails
the vm's will fail over. I just want to make sure the Hyper-V Replication will work in this way.
Vincent Sprague

I need the storage replication aspect, I currently have the two servers in a cluster and the vm's failover but storage is my problem, our shared storage solution is junk and I need to find a way to get around that.
Vincent Sprague
1) For Hyper-V Replica you don't need to have shared storage as Windows will replicate source VHDX with some minor delay to a destination VHDX.
2) You may also take a look @ Storage Replica (part of the upcoming Windows Server 10) as it may do a better job for you because of the synchronous nature. See:
Storage Replica and Hyper-V

Good luck :)

Hyper-V Replication Certificate Question

Hi,
Possibly a common question so apologies if it's simple.
My main server is HV1.company.local
My second server will be cloud based and standalone in a workgroup, let's call it hv2 and for arguments sake I'll add the DNS entries of hv2.mydomain.co.uk
and a certificate for this address.
Certificates will obviously need to be internet facing so will go for HV1.companydomain.com for the first server.
Do I just use internal DNS to sort out the fact that the server name is .local?
Anyone with experience in this set up with best practice and any gotcha's would be much appreciated,
Cheers,
JJ

Hi Sir,
>>My second server will be cloud based
Based on my understanding of your case , first you may ensure two hosts can access the IP of each other directly (whatever dns or hosts file ).
If the network prerequisite is met , then we can think of it as a workgroup environment and build certificate-based replication for two hyper-v host :

Will Hyper-V Replication Manager move a VM without shutting it down?

Scenario
Let say I have two sites (Primary And DR). I have my production VM's running on my Primary Site. If I protect them with Hyper-V Replica the VM is replicated and I can bring the VM up manually in the DR site. So I know that process work. I am trying
to minimize the outage of an app and the time it takes to bring the VM up and running. I have a database server in the primary site. I want to be able to move the VM hosting the database server to the secondary site without shutdown or with minimal downtime.
Question
Can I use Hyper-V Replication Manager to migrate the VM with the database from the Primary Site to the DR site without downtime for the SQL server? When I mean downtime for the SQL server is that clients can continue to connect to the database and access
the data in the database while I am migrating the VM.
This is needed to maintain availability during DR testing of the Production environment.
Thanks,
Carlos

Hi Carlos,
For DR drills you can use the test failover. A
test failover can spin up a test virtual machine for the production virtual machine. This VM can run in an isolated environment and does not affect the production environment. Your SQL server will have no outage while DR testing.
A test failover can be executed on an individual virtual machine or a recovery plan. This can orchestrate the drill as close to a real failover which recovers the application in a planned manner.
Hope this pointer helps.

Hyper-V Replication over Dedicated LAN and "is alive" checks over Corporate LAN

I am testing Hyper-V replication to see if it will be a suitable replacement for the ArcServer RHA product. One thing I am struggling with is configuring the replication to use the dedicated LAN, but still have the host servers verify over the corporate
LAN.
I have seen the blogs on how to use a dedicated route and editing the hosts file to get replication to use the dedicated LAN, but that also changes the LAN in which the host servers communicate. It seems to me that if the corporate LAN were to go down
on the master server, I wouldn't be able to fail over the virtual machines to the replica server without first having to connect into the master server through the dedicated LAN of the replica server to shut down the virtual machines.
I need to be able to fail over to the replica server if the corporate network connection on the master server drops without having to go through the extra steps of connecting into the master server first.
Is it possible for the two items to be separated? Can I tell Hyper-V to replicate using one specific IP destination on the dedicated LAN and have the replica server check to see if the master is live over the corporate LAN?

Hi Telrick,
>> It seems to me that if the corporate LAN were to go down on the master server, I wouldn't
be able to fail over the virtual machines to the replica server without first having to connect into the master server through the dedicated LAN of the replica server to shut down the virtual machines.
I want to say that there are "planned fail over" and "unplanned fail over " , the latter applies the primary server crashing (you can select "failover" on "replica server " then the VM will start up ,after the primary
server online again you can do "reverse" )
The point is that you can not use hyper-v replica as a backup (it will lost little data which have not yet been replicated to replica server when "unplanned fail over" happens )

Hi!
I have a window inheritance and implementation question. I'm using
Forte 3.0.J.1.
I have a super (base) window with a PushButton on it. I want to
handle the Click event of the button in this super window therefore
I create an event handler.
<MyBtn> : PushButton
I create a sub window inheriting from the previous super window.
I put some data widgets on it and group all of them (the inherited
button as well) into a GridField. When I set the mapped type of the grid
the name of the inherited PushButton widget changes:
<MainGrid.MyBtn> : PushButton
When I run the application I get a SystemException with the
message:
Attempt to register an event on a NIL object (qqds_C_FieldWidget, 10).
Traceback:
SuperWindow.EH at line 0
SubWindow.Display at line 5
C++ Method(s)
UserApp.Run at offset 105
It is quite understandable that in runtime there is no widget called
<MyBtn>
and the event handler of the super class fails.
But what I don't know : after specifing a mapped type of a GridField why
changes
the name of those widgets that haven't got mapped type e.g.: PushButton,
PictureButton etc.
How to solve this situation?
I made a sall example which i send in attachment.
Thanks for any help and advice in advance...

DPM 2012 R2 and Hyper-V Replication, huge conflict and failure to backup

I have recently created new 2012 R2 servers with DPM 2012 R2 in attempts to upgrade an environment.
When attempting to create Protection Groups for Hyper-V VM, DPM will consistently omit any VM that happens to have Hyper-V Replication enabled, whether that server is the primary VM instance or a replica VM instance. ALL other Hyper-V VMs are listed,
only those with Replication enabled are omitted. This happens on both DPM 2012 R2 servers, exactly the same results - all VMs without Hyper-V Replication enabled are listed, none of the VMs with replication enabled are visible in the list.
Obviously we need to be able to backup VMs with Hyper-V replication since replication is only a tiny portion of a DR strategy, it doesn't cover ANY recovery scenario other than the loss of the primary VM - it doesn't allow for restoring any missing or damaged
files or undoing any other changes to the VM.
The DPM 2012 R2 server have the latest update rollup (#4) applied and the protection agents have also been updated.
Looking for some hints since DPM 2012 R2 is supposed to support backing up both the primary and replica VMs, especially when the Hyper-V host if Server 2012 R2.
Might have to use Windows Server Backup or Veeam's free Hyper-V backup since aside from enabling Hyper-V replication to keep a couple snapshots, DPM isn't a viable backup options in combination with Hyper-V replication.

As per the following blog:
http://blogs.technet.com/b/dpm/archive/2014/04/25/backing-up-of-replica-vms-using-dpm.aspx
you should be able to backup Hyper-V VMs even if they are replica VM.
When you configure DPM to protect both primary and recovery hosts, VM will appear on any of the Servers as it will have the same GUID.
So, protect primarya nd recovery hosts using different DPM or if you want to protect both primary and recovery using same DPM, make sure that you check both servers so as to discover VM.

Limit Hyper-V Replication Data Transfer Rate

Hello,
i need to limit data transfer rate for Hyper-v replication because between two Datacenter have bandwidth limitation.
Please suggest

You can use the New-NetQoSPolicy cmdlet to set the throttling limits -
http://technet.microsoft.com/en-us/library/hh967468.aspx. Based on the destination port (the port on which the replica server has been configured to receive replication traffic - maybe it's port 80 in your case) or the destination subnet, you can specify
a throttling value (-ThrottleRateActionBitsPerSecond) or assign a weight (MinBandwidthWeightAction).
Eg: New-NetQosPolicy "Replica traffic to 8080" –DestinationPort 8080 –ThrottleRateActionBitsPerSecond 100000
or check the link to Thomas blog

Hyper-V Replication Question

Hello,
I just completed watching some YouTube videos and reading some helpful websites but still had a quick question. I have a .110 network in LocationA and a .60 network in LocationB.
Both locations use static IP addresses. I can ping both locations from each other. If I want to replicate a VM from the .110 network or LocationA to the .60 network which is LocationB would this be possible since both locations have different networks? If
I want to replicate from the .110 network, would my .110 network settings on the VM still be configured on the VM in the .60 network? If this is the case then when I turned on the replicated VM it would not be able to join the network without modifying the
NIC settings. I was hoping someone could explain this process a little better or more in-depth so I have an idea of what I'm doing.
On a different note as long as your two host servers are Server 2012 R2, can you replicate Server 2003 and Server 2008 systems or is it only for 2012 R2 VMs? Any and
all information is helpful. Thank you!
Pat

Hello Pgrantland,
I was checking some documents about this wonderful feature and I found this:
2.3 To enable replication for a virtual machine
9. A dialog box appears indicating that replication was successfully enabled. In this dialog, click the Settings button
and provide settings to configure the network that the virtual machine will connect to on the Replica server. The Replica virtual machine does not automatically connect to any network on the Replica server (after a failover) by default,
so these settings are important. You can configure the network settings so that the virtual machine will connect to a different network after a failover to the Replica server than it used when it was on the primary server.
Step 2: Enable Replication
https://technet.microsoft.com/en-us/library/d5d9e9f2-0f21-4d82-aa90-45e194de5ac9#BKMK_2_3
These steps are configured before you finish the wizard to enable Hyper-V replica on a VM.
Regarding the other question as far as I know a VM is just a VM from the Hyper-V side, the replica does not look what OS you are running.
The only thing is that if you a re planing a VM to be replicated check that the hardware elements configured on the settings of you VM are able to be replicated.
There are scenarios on which hardware configured on a VM makes that the VM is not supported for replica and you cannot replicated as long as those elements are configured on the VM.
For example "Fibber Channel adapter" (Virtual SAN) and "Virtual hard disk sharing" are not supported to replicate.
Hope this information help you to reach your goal. :D

Hyper-V Replication - Subnet Configuration Between Datacenters?

I'm designing a DR solution in a geographically separate datacenter which will use Hyper-V 2012 R2 Replication to replicate several of our VMs to another Hyper-V cluster. The VMs will run a mix of Linux and Windows, with the Windows servers being Exchange,
SharePoint, WSUS, etc.
I currently have a static IP assigned to all servers and VMs, i.e. I'm not using static DHCP reservations.
I have the ability to extend the private LAN subnet (let's call it 192.168.1.1) between the two datacenters over the public Internet using my firewall's VPN capability, but I'm wondering if there is a recommended best/better practice for this?
Is it okay to extend the subnet so in a fail-over scenario I can just power the VMs on in the DR datacenter without much manual intervention? Or would it be a better idea to configure my servers with a static DHCP reservation, so when they come up in the
DR datacenter they can pull an IP on a unique subnet?

Hello Matt,
The answer is yes for Hyper-V 2012 R2, however this feature was available only for Windows Guest OS'es in Hyper-V 2012.
This works only on synthetic network adapters, not legacy network adapters, and it requires Windows XP SP2/Windows Server 2003 SP2 and newer OS'es to be running on the virtual machine to work. This
also works with Linux virtual machines that are running the latest Linux distributions.
As a good practice is to complete the failover TCP/IP configuration on the primary virtual machine with its normal IP configuration. In that way, if the replica is ever activated, replication is
reversed, and the virtual machine is then failed back to what was the primary, and the correct IP address for the primary location can automatically be put back.
Hope this help.

Hyper-V replication across versions (2012 to 2012 R2 and vice versa)

Does Hyper-V support cross-version replication? In other words, can Windows Server 2012 Hyper-V replicate to Windows Server 2012 R2 Hyper-V server? Vice versa? I tried looking for documentation or blog posts about this but couldn't find any.

Hi,
Base on my test, the Hyper-V 2012r2 can't replicate to Hyper-v 2012.
Additional, the following similar thread may will helpful of your question.

PL/SQL Ad-hoc Reporting Implementation Questions

Recently, I have been put on a development team that is developing a small reporting module for one of our applications.
I'm trying to mask the underlying structure from the application by having the application run PL/SQL procedures which return REF CURSORS to the client with the requested data. Right now I'm struggling with how to implement the PL/SQL in the best fashion.
Since this is a reporting tool the user has many combinations of selections. For example at a high level this application has a combination of multiple dropdowns (4-6), radio buttons, and check boxes. As you can see this results in a high amount of possible combinations that have to be sent to the database.
Basically, the user chooses the following:
1. Columns to receive (ie different SELECT lists in the PL/SQL)
2. Specific conditions (ie different WHERE clauses in the PL/SQL)
3. Aggregate functions (SUMS, TOTALS, AVERAGES based on #1 and #2)
4. Trends based on #3.
So... with that said I see two possibilities:
1. Create a static query for each combination of parameters (in this case that would most likely result in at least 300 queries that would have to be written, possibly 600+).
The problem I see with this is that I will have to write a significant amount of queries. This is a lot of front end work that, while is tedious, could result in a better performing system because it would be a parse once, execute many scenario which is scalable.
The downside though is that if any of the underlying structure changes I have to go through and change tens of queries.
2. Use DBMS_SQL and dynamically generate the queries based on input conditions.
This approach (possibly) sacrifices performance (parse once, execute once situation), but has increased maintainability because it is more likely that I'll have to make one change vice a number of changes in scenario 1.
A downside to this is that, it may be harder to debug (and hence maintain) because the SQL is generated on the fly.
My questions to all is:
1. Which is the approach that would best manage maintainability / performance?
2. Is there any other approaches to using PL/SQL as a reporting tool that I am not thinking of?
The database is 10.2.0.3, and the 'application' is PHP 5.1 running on IIS 6.
If you need me to provide any additional information please let me know.
Thanks!

Ref cursors are an ugly solution (different though in 11g).
You build a dynamic SQL. It must/should have bind variables. But a ref cursor does not allow you to dynamically bind values to bind variables. You need to code the actual bind variables into the code as part of the open cursor command. And at coding time you have no idea how many bind variables there will be in that dynamic SQL for the ref cursor.
The proper solution is DBMS_SQL as it allows exactly this. Also one of the reasons why APEX uses this for its report queries.
The only sensible way to implement this type of thing in PL/SQL is by not trying to make it generic (as one could with DBMS_SQL). Instead use polymorphisms and have each procedure construct the appropriate ref cursor with bind variables.
E.g.
SQL> create or replace package query as
2 procedure Emp( c in out sys_refcursor );
3 procedure Emp( c in out sys_refcursor, nameLike varchar2 );
4 procedure EMp( c in out sys_refcursor, deptID number );
5 end;
6 /
Package created.
SQL>
SQL> create or replace package body query as
2
3 procedure Emp( c in out sys_refcursor ) is
4 begin
5 open c for select * from emp order by 1;
6 end;
7
8 procedure Emp( c in out sys_refcursor, nameLike varchar2 ) is
9 begin
10 open c for select * from emp where ename like nameLike order by 1;
11 end;
12
13 procedure EMp( c in out sys_refcursor, deptID number ) is
14 begin
15 open c for select * from emp where deptno = deptID order by sal;
16 end;
17 end;
18 /
Package body created.

New Portal Implementation Questions?

Hi,
We've just started a Portal Implementation in our company. Our environment is as follow:
- EP 6.0 SP9 (NW04 SR1 version)
- SAP 4.6C System (WPPI installed)
- Lotus Notes/Domino (we are using Domino LDAP)
My Questions are as follow:
1. Can we integrate Domino LDAP with portal? If not how can we access domino user database in this environment?Because all company users exist in domino database but small subset of company users have SAP user.
2. Currently I've created a system for 46C r3 system in system landscape and set it to use UIDPW for user management. I've mapped one of portal user with a SAP user and created iviews to run with wingui and webgui. All worked successfully. My question is that if there is any wey to enable SAP users to logon Portal without mapping? Online Docs. says that it is not possible to use R3 systems other than based on 620 WAS as a datasource for UME.
Regards

Hi Huseyin,
You need to create system in EP.
System administration>System Configuration>system landscape-->
1) create one folder like "system"
2) create system in the above folder
3) Enter all the details of R/3 System
4) create Iview and link to the R/3 system
you could allways look at the manual:

hope it helps,

Metro Ethernet implementation questions

I am planning a Metro Ethernet upgrade for a network I manage. This is the first time I’ve implemented Metro on any network. I’m looking for some suggestions and answers to a couple questions regarding this upgrade.
The current network is Hub and spoke connected by copper lines to 17 different locations from a DS3 @ our HQ. HQ also has a DS3 to the internet which the branch locations go out for internet. At our branches we have a private and public network on different subnets. Each branch location has either a T1 or bonded T1 connected to a Cisco 2801 router then to Netgear PoE managed switch(s).
The upgrade of the DS3 for internet is going to 100 meg. The data side will also be 100meg at HQ, 10meg to our small locations and 100meg to the large.
My question is what do I need to be aware of on our existing network that must change to get this working?
1)      Will I simply go from the layer2 Metro Switch to our router?
2)      Should I remove the router and go directly to the Netgear switch?
3)      Do I need to VLAN the private and public networks?
4)      Do I need to change routing tables?
Thoughts and/or suggestions welcome.
Let me know if more information is required to assist in answers.
Thanks

Hi,
I think it would be better to include Cisco Account Manager/SE for this upgrade, they can guide you better and can come up with LLD for this upgrade, otherwise upgrading your 17 sites without proper planning can cause you serious issues.
