CF Licensing on two front end web servers

I'm currently running CF 9 Standard on a since server that runs as my web and db server. I use Rackspace Cloud btw.
I've been thinking about changing my infrustructure around so it would look like this:
- 1 Load Balancer
- 2 Web Servers
- 1 Database Server
My question is about licensing on the 2 web servers.
- Is it possible to use a single CF Standard license to cover both web servers (since they are just syncing each other, they are basically the same server but split into two separate virtual machines), or would I need to purchase 2 individual licenses to make this work?
Any help or advice is appreciated. Thanks!

Thanks vishu,
I can read the license agreement, but it's the interpretation of legal wording that I'm having troubles with. Basically, I'm looking for a real world YES or NO to my question. I'm sure others have had this question, that's why I came to this forum.

Front-end web servers with different OS

Hi everybody,
is it possible to build a SharePoint farm with front-ends with different OS (W2k8R2 & W2012)?
Thanks in advance,
Sergio Calleja

There should be no issues in having two WFEs running with different operating systems. If MOSS 2007 version can successfully support a mix environment of having two different OS on WFE then why not SharePoint 2013.
But I recommend to set a test environment first and test your mixed setup environment. This will gain you more confidence and sure possibility to implement it on production. Else I see no compatibility issues even if you directly implement the mixed WFE
environment on SharePoint 2013 production.

Can Sharepoint Front end web server running on VMware protected by DPM 2012

Hi,
We use Vmware environment, have SharePoint on Vmware server.
Is it possible to be protected by DPM 2012?
Because came across " http://technet.microsoft.com/en-us/library/hh757870.aspx " where it says ---
Front-End Web Server Running on Hyper-V Virtual Machine
With DPM, you can perform backup and recovery of virtual machines that are running on Hyper-V. For more information about how to protect Hyper-V virtual machines, see Protecting
virtual machines with SMB storage andRecovering virtual machines. If the front-end Web server of a SharePoint farm is on a computer
that is running on any other virtualization technology, you can protect it just as you would a physical computer
Baskar.S

Thanks Mike, Are you sure because it says - You can perform backup and recovery of virtual machines that are running on Hyper-V,
If the front-end Web server of a SharePoint farm is on a computer that is running on any other virtualization technology, you can protect
it just as you would a "physical computer" - Does physicals mean sharepoint on physical machine or JUST a physical machine
This were I doubt :)

Using Weblogic as a front end web server

Hi all, recently there has been a push for us to investigate moving our Iplanet
web servers to Weblogic. So our architecture would be WLS web instances on the
front and passing back to WLS app servers on the back end. We would need to run
SSL and none SSL and handle certificates and multiple applications on each web
server as well as serve up static content. Has anybody had any experience with
going to this set up, and if so would you recomend it ? It looks way harder then
setting up a Apache or Iplanet web server.

You should check out 8.1, SSL configuration is simpler there.
I would say in general that the main weakness of WLS as a web server
is on
the administration side of things.

Named Pipes provider, error:40 could not open a connection to sql server. Only happens on one of the front end SRS servers

when testing a datasource connection I get the following error.
Named Pipes provider, error:40 could not open a connection to sql server.
I've read all the posts on this and nothing works. This is a scale out deployment and the connection
works from the other server I have setup with SRS that is connected to the same backend SRS databases. It just doesn't work from one of the SRS front ends. I'm at a loss.. please help

Enable both named pipe and TCP communications.
Make sure client is using the same (named) pipe name as server for connection.

NLB Web Front End (WFEs)servers & Clustering IIS Application Pool between the two WFEs

Hi All,
I have just encountered a very bad experience in my Production environment.My topology is as follows: NLB WFEs, MOSS APP server, Cluster DBs, DCs.
NLB on the WFEs is working fine. However, for some unknown reason, one of my site under the Application Pool in IIS Manager was stopped on one of the WFE and the site was down. NLB did not redirect request to the second WFE server.
My question is: How can I make sites under the Application Pool highly available? If any site is in a stopped state, there should be a mechanism in place to redirect request to the Application Pool on the second NLB WFE.
Kindly help and advise.
Thanks all.

Hi Noah,
The best way of knowing whether the Application pool is down is to monitor it.
Using appcmd, i can check the state of an application under the application pool.
I want to create a schedule task which will check the status of the application pool and in case the application pool is stopped, to send me an email as alerts.
Using Powershell and appcmd, can you guide me on how to do the above i.e I want to use Powershell with appcmd to check for availability of an application pool. If the status is stopped, send me an email as alert.
Thanks.

Ports between two front end pools

Hi all,
We plan to build 2 pools in two geographical locations. They are active-active sites, in case of one site failure we would move all the uses from the failed site to the surviving sites.
What are the ports that need to be open between these pools?

2 edge servers and 2 front end servers?

Good morning/afternoon/evening Technet,
We're about to go to production with Lync 2013 standard with the following.
1. 2 front end servers w/ standard edition
2. 2 edge servers
We want to set it up so that 1 front end and 1 edge server will be at a location of ours a couple miles away. We want to setup the other front end and edge server at our main office. For disaster recovery purposes I know that I can keep the two front ends
pooled but as far as the Edge servers go, would it be best to have 1 active and the other edge turned passive? Is there a way that I can put the two edge servers in the same pool?
Thanks for all the help guys and gals!
-Liqsh0t

Hi,
Each Site can use a separate Edge Server to support external login process.
However, it is possible to use single Edge server for both pools. The user from the other site has to connect to the only edge and then route though the WAN link to go to its own pool. Access Edge is responsible for proxying SIP traffic for remote clients
to the next hop, which can be a Director or a Lync pool.

Problems with one of the front-end servers (service wont start)

Hi,
Having a pool with two front-end servers (Lync Server 2013 on Windows Server 2012) and I cannot get one of servers to work properly.
The Front-End service is not starting.
Have removed both servers from the topology and installed one at the time. When adding the second server to the pool the service never starts, its in starting state and a bunch of error messages appears:
- Server startup is being delayed because fabric pool manager is initializing.
Cause: This is normal when Pool is bootstrapped and indicates that the Front-End is waiting for a quorum of other Front-Ends to be started.
- Pool Manager failed to connect to Fabric Pool Manager.
Cause: This could happen because insufficient number of Front-Ends are currently active in the Pool.
I have tried restarted one at the time, both at the same time...
Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery
Reset-CsPoolRegistrarState -ResetType FullReset
I have also had a look at the kb saying that there could be a certificate issue. So I have ran that script but no certificate is misplaced in any store.
I have removed the front-end certificates and requested new ones from the internal CA, I have also done the same to the OAuth certificates.
How to proceed?

Hi there,
if you are still receiving, the same error, please try to shutdown the first Front-End Server, and give time for the services to start, however I would like also to add that with Lync server 2013 the Enterprise pool requirements is to have 3 Front-End Servers
in a pool instead of 2, because of introducing the brick model architecture.

2 Front-end vs 3 Front-end server

Hi everyone,
Our front-end pool will consist of 2 front-end servers for high availability. One front-end server should support 10,000 users, but since the recommendation for a front-end pool is 3 servers, i want to know if deploying only 2 could be a real issue. What
I understand from the Technet documentation is that the way user data is stored (1 primary copy and 2 backup copies) is one reason (but I would thing not enough reason for us as a company of 1200 users) and that you need to shutdown and bring them up again
in a specific order. Am I missing something what would definitely make me deploy 3 front-end servers?

I'd say just never do two front end servers, it's not recommended at all.
Check out these links to learn more and see some experiences:

Per TechNet "If you do not want to deploy three Enterprise Edition Front End Servers and want high availability and disaster recovery, we recommend you use Lync Server Standard Edition and create two pools with a paired backup relationship. This
will provide the best high availability and disaster recovery solution with only two servers."

Front End Service is not starting

Hi ,
Any one can help me to resolve this issue.
I have one enterprise edition front end server .if i try to start the front end service it give the following error
Server startup is being delayed because fabric pool manager is initializing.
Cause: This is normal when Pool is bootstrapped and indicates that the Front-End is waiting for a quorum of other Front-Ends to be started.
Resolution:
If this event recurs persistently, ensure that 85% of the Front-Ends configured for this Pool are up and running. For 2 or 3 machine Pools, initial cold-start of the Pool requires all machines to be started. If multiple Front-Ends have been recently decommissioned,
run Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery to enable the Pool to recover from Quorum Loss and make progress.

If understand the problem Correctly You one Lync enterprise edition installed is that right?
If yes Please note For a recommended Lync Server 2013 EE pool deployment, there should be at least three Lync Server 2013 front-end servers in the EE pool.
http://technet.microsoft.com/en-us/library/gg412996.aspx
We recommend that all your Enterprise Edition Front End pools include at least three Front End Servers
Also refer Why 3 server pool?

If you just want one Lync server please install Lync Standard Edition
Front End Pools with Two Front End Servers
We do not recommend deploying a Front End pool that contains only two Front End Servers. If you do ever need to deploy such a pool, follow these guidelines:
If one of the two Front End Servers goes down, you should try to bring the failed server back up as soon as you can. Similarly, if you need to upgrade one of the two servers, bring it back online as soon as the upgrade is finished.
If for some reason you need to bring both servers down at the same time, do the following when the downtime for the pool is finished:
The best practice is to restart both Front End Servers at the same time.
If the two servers cannot be restarted at the same time, you should bring them back up in the reverse order of the order they went down.
If you cannot bring them back up in that order, then use the following cmdlet before bringing the pool back up:.
Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery -PoolFQDN <FQDN>

Lync 2013 On Prem - Front End Pool - Second server in pool becomes unavailable when first server is offline

We have one front end pool, that contains 2 front end servers running Lync Server 2013.
When the first server, LFE01 goes offline (to be restarted for instance), the second front end server LFE02 in the same pool's Lync services will suddenly stop and will refuse to start until LFE01's Lync services have started again.
During this time, the Lync client will go from full functioning mode whilst LFE01 is up and running, to reduced functionality (when LFE01 is restarting), to the user being signed out of Lync and not able to log back in. As soon as LFE01 comes back up, users
can log back in to Lync.
We'd ideally like LFE02 to take over the front end server role whilst LFE01 is restarting, and vice-versa.
Checking the event logs on LFE02, I can see the following errors when LFE01 is offline:
This process was not able to update its health status
The Audio-Video Conferencing Server failed to send health notifications to the MCU factory at https://frontendpool.contoso.com:444/liveserver/mcufactory/.
Failure occurrences: 30, since 7/11/2013 3:40:38 PM.
Cause: Either the Front End service is not running, or poor network connectivity.
Resolution:
Verify that the Front End Service is available, and its machine is visible over the network.

Does the first server in the pool need to be up at all times for the second server to be running? If so, I may need to re-plan my redundancy.

I can't believe how inaccurate these statements are.
Yes as per Microsoft it is best practice to have 3 FE in a pool but that absolutely does not mean that if you have 2 FE server in a pool that your pool will stop working!!
In case when you do have 2 FE servers in a pool your Back End primary database server will act as a vote to keep the quorum for single server still left in a pool and all your clients will keep operating in a pool with one FE still running.
The problem with having 2 FE in a pool as per Microsoft documentation is as follows:
If one of the two Front End Servers goes down, you should try to bring the failed server back up as soon as you can. Similarly, if you need to upgrade one of the two servers, bring it back
online as soon as the upgrade is finished.
If for some reason you need to bring both servers down at the same time, do the following when the downtime for the pool is finished:
The best practice is to restart both Front End Servers at the same time.
If the two servers cannot be restarted at the same time, you should bring them back up in the reverse order of the order they went down.
If you cannot bring them back up in that order, then use the following cmdlet before bringing the pool back up:.
http://technet.microsoft.com/en-us/library/gg412996.aspx
I tested this in my environment which I currently am running with 2 FE servers and I can categorically confirm that pool will continue operating.
However, with all this said I did notice that clients with connection to FE server that is shut down take anywhere from 2-9 min to reconnect. I was trying to figure out why such a long delay until clients reconnect. Possibly it might be because there are
2 FE servers in a pool and Back End server is taking a while to vote in turn delaying auto reconnect process for clients. Second possibility that I'm looking into is that we deployed HLB for sip traffic internally as well and I'm curious if using DNS LB would
fix this delay.
I'm just so disappointed how inaccurate some of these accepted answers above are.

Front end and back end questions

Hi,
If I want to develop a web base SOA application by using Jcaps, I have several question want to ask.
1.) In the front end, if i create the page by using eVision to create the page
flow and the page layout, how can I match the fields of the page (such
as the username, email, tel no... with the back end web services?
2.) Does the flow of the front end web pages are control by the page flow in
eVision? When will the eVision supported AJAX or JSF?
3.) What is the use of the eInsight Business process manager, does it
control all the back end flow, such as the flow of each web services?
Does Jcaps has the Bpel engine to control the flow of web services?
4.) I know that in JBoss, there is a jBPM server to control the flow of the front
end pages, does JCAPS has this kind of server?
5.) If i want to connect to the Database? I know that there is a eTL to extract
the data from the database, it is true? Or do u recommend to connect the
database directly through the web services by using JDBC or other
framework as well?
6.) If I have an existing application that is developed by .Net (With no web
services). How can i integrate with other systems? What can I do in order
to reuse the system? Or what Jcaps can do in this manner?
Thanks for you reply! ^ ^

Generally, back-end would consist of the taks associated with configuration of data targets (ODS, Cubes), working with extractors, mapping data to the data targets, writing transfer/start rtn/update rules, and creating Infopkgs/ Process Chains.
Front-end deals with the use of the BW - writing queries, workbooks, web (although I think some of the infrastructure aspects of web reporting. e.g. javascript/templates might really could be considered backend). Think of Front-end as all of the client/customer/user facing components.

Front End for Upgrade 3.5

We are upgrading from 3.1 to 3.5. I'm assuming we will need a different front-end for the 3.5 vs. 3.1. Can someone please verify and also is there a easy way to switch between the two front ends in order to connect to both 3.1 and 3.5
Will reward points as always.
Richard

We're in the middle of upgrading from 3.1 SP 22 BW w/6.20 SAPGUI. We've only upgraded a sandbox BW server at this point, but we have upgraded all BW team members with SAPGUI 6.40 FEP 5 and can successfully connect to our 3.5 and 3.1 BWs.
