Load balancing and HA for office web apps server Lync 2013

Hi,
I have 12000 users, 3 FE servers in a pool, 2 edge server in a pool, HA required, IM/presence, A/V, WEb conferencing required. plan to have 2 office web apps server a farm with HA, below are my queries
1. which type of load balancing i need....DNS or HLB for office web app servers? if its HLB then is it mandatory?
2. i have already 2 HLB for FE pool .. one for externa url , one for internal URL...can i use the same HLB for office web app servers ?
3. one more question regarding EDGE pool load balancing, can i use the same HLB in EDge pool also that i am using for FE pool?

Hi,
1. which type of load balancing i need....DNS or HLB for office web app servers? if its HLB then is it mandatory?
WebApps runs on https and you cannot load balance http traffic using DNS load balancing. you need to have a HLB.
2. i have already 2 HLB for FE pool .. one for externa url , one for internal URL...can i use the same HLB for office web app servers ?
you can use the same HLB for that
3. one more question regarding EDGE pool load balancing, can i use the same HLB in EDge pool also that i am using for FE pool?
for that one, you probably need a separate HLB.

Office web Apps server Lync 2013

Hi All,
I have logged onto my Volume licensing site and could not search Office Web Apps servers for download?? I wonder how do i download it?

Hi channavera,
Office Web Apps Server was removed from the Microsoft Download Center. Now it only was available for
download under Volume Licensing agreements. For more information please read the FAQ below or visit the site Volume Licensing
Service Center.
FAQ
Why is Web Apps Server being removed from the Microsoft Download Center?
VLSC is best suited as the location from which to serve all customers according to their agreements with Microsoft.
What about existing installations? Do I need to re-license them?
No. Web Apps Server installations and/or downloads that occur before 11/24/14 will continue to be licensed for free viewing.
Will there be an evaluation version for Developers and IT Pros?
Evaluation availability will continue on MSDN for subscribers. Additionally, Volume License agreements allow for product evaluation.

Office web Apps server Lync 2013 Certificate

Hi,
I'll be installing Office web app (OWA) server with Lync 2013 std edition. External users access is disabled but federation is enabled, mean OWA will be exposed to internet as wabweb.contoso.com, the interal host name of OWA server is owa.contoso.local
Does the certificate on the on OWA server need to have owa.contoso.local and certificate principle name and wabweb.contoso.com as SAN? or only owa.contoso.local is enough?

It really depends on how you publish the server to the internet. You have some options. If you are publishing this via a reverse proxy, internally you would have a private cert with .local on it and the public name on the reverse proxy. If you are
punching a firewall hole/NAT directly to the server your best option is to use a public cert on that server directly.
That all said, personally I like to make both the internal and external farm URL the same, and use a public cert on the server (if no reverse proxy is in play). So I would actually enter the OWAS Farm as wabweb.contoso.com in topology builder, than
when creating the farm via PowerShell make that both the internal and external URL and get a certificate with a single name on it of wabweb.contoso.com.

Hi,
Sorry to inform you that these new features are specific to cloud Excel Web App in both SkyDrive and Office365. There is no update available for on-premise Excel Web Apps installed locally
yet. Thank you for your understanding.

High Availibity solution for office web app server 2013 for Sharepoint 2013

I have a scenario with the three nodes SP1 , SP2 and DR-SP with server 2012 standard, each running SharePoint 2013 enterprise, All of three nodes are members of single SharePoint farm that spans two data centers.Primary Data Center have two nodes SP1 , SP2
and DR data center have one node DR-SP of share point 2013.
For Office webapp server i have two nodes OWA1, and DR-OWA with server 2012 standard, that spans between two data centers.Primary Data Center have OWA1 and DR data center have one node DR-OWA of office web app server.
Currently i have configured office web app on primary data center node OWA .How i can enable high availability of office web app server in case of primary data center outage.Please guide.

WAC servers on a single farm must be in the same data center. The WAC configuration you've proposed is unsupported. Build a separate WAC farm in the secondary data center and attach it to the SharePoint farm only in the event of a disaster.

Office Web Apps server / Lync server 2013

Hi I have installed a Lync 2013 Server and Office Web Apps Server. Configured Lync topology, Office Web Apps farm and certificates.
However when i start the services i get this error message in the log saying Office Web Apps discovery failed.
Event ID: 41033
Description:
Office Web Apps Server (WAC) discovery failed, PowerPoint content is disabled.
Attempted Office Web Apps Server discovery Url:
Received error message: Invalid Uri syntax for WAC configuration
The number of retries: 1,
Cause: Office Web Apps Server may be unavailable or network connectivity may have been compromised.
Resolution:
Check HTTPS connectivity from this box to the Office Web Apps Server deployment using the discovery Url.
I can access the OWAS server Url from Lync Server
Connecting to the HTTPS discovery URL is working fine, and brings up the XML-page (after i click "show all content").
The two servers are located on the same internal network, DNS resolves fine both ways, and no firewall rules blocks any connections between the two. Can anyone please help me figure this out?
Only identical problem found online is here (Invalid Uri syntax for WAC configuration):
http://blogs.technet.com/b/dodeitte/archive/2012/09/10/office-web-apps-server-amp-lync-server-2013.aspx
He resolved the problem by assigning a new OAuthTokenIssuer certificate. This however did not fix the problem in my case.

Sverre A. Veel

Hi,
In addition, please make sure you have restarted front end and office web apps server after reissuing the certificate.

Using Office Web Apps Server with SharePoint Foundation 2013

I want to know whether I can configure Office Web Apps server to edit Excel documents on a SharePoint Foundation 2013 site.
I came across a TechNet article that states that "When used together with SharePoint Server 2013, Office Web Apps Server provides updated versions of Word Web App, Excel Web App, PowerPoint Web App, and OneNote Web App".
However, later in the same article, it states "If your organization licenses Office 2013 through a Volume Licensing program, you can enable Office Web Apps editing for SharePoint 2013 on-premises" (without mentioning Foundation or Server).

Hi Lemesnil,
The Office Web App server should support the Edit licenses for SharePoin Foundation 2013, Office Web App is free to
download, you can also try installing and configuring in a test environment, see more from the below article applied to SharePoint Foundation 2013.

Office Web Apps Server Certificate For External

Hi guys,
I am requesting a DigiCert certificate for my environment Exchange 2013.
Can I include the SAN name for Office Web Apps server, such as externalowa.domain.com in to the Exchange generated certificate?
From theory wise it seems logic, but kind of uncertain.
Thanks and Regards,
Low.

Hi Nithyanandham,
Thanks for the prompt reply
I will just list down what I did to be more clear.
I generated a CSR from Exchange 2013 with the following
Webmail.domain.com - for Outlook Web Access, Outlook Anywhere, ActiveSync
Autodiscover.domain.com - for AutoDiscover purposes
Can I include the externalowa.domain.com, which is for Office Web Apps server
Reason is because the Exchange server and Office Web Apps server is located differently. Am I doing the correct way?
Thanks and Regards,
Low

Office Web Apps Server - Access is denied

Hello,
I was able to create an Office Web Apps server and was able to create a new farm for that server all without any issues, everything works great.
Unfortunately right after creating the farm, when attempting to run any other related powershell commands such as:
Get-OfficeWebAppsFarm
Remove-OfficeWebAppsFarm
I get this error in powershell:
Get-OfficeWebAppsFarm : Access is denied.
At line:1 char:1
+ Get-OfficeWebAppsFarm
+ ~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Get-OfficeWebAppsFarm], SecurityAccessDeniedException
    + FullyQualifiedErrorId : System.ServiceModel.Security.SecurityAccessDeniedException,Microsoft.Office.Web.Apps.Adm
   inistration.GetFarmCommand
Although everything is actually working on the server, I'd like to be able to use those other commands in the future so I can check configurations, use "Remove" for running updates, etc... Unfortunately it appears as though this Access is
denied error may interfere with those activities.
Has anyone seen this before?
Thank you

Hi,
According to your post, my understanding is that you failed to run any other related powershell commands after creating the farm for Office Web Apps server.
If the account trying to get OfficeWebAppsFarm does not have local admin access on the machine you will simply get an “Access is denied”.
Please make sure you have the permission to run the commands.

Office web apps server 2013 install issue

Dear All,
when i install office web apps server in a new server(OS:Windows Server 2008 SP1) with PowerShell Scripts it keep the installing status for more than four hours .
what should i do now ,i think it should not take such long time as i do the same installing in the other server before which takes less than 1 hours.
beg your suggestions!

Hey
please take these points into your considerations:
- OWA server can be installed on Windows server 2008 R2 or Windows server 2012
- Log in as administrator and preferred to use domain administrator account specially to create new office web apps farm
- run the script

High availability for Lync 2013 persistent chat server and office web app server

I have 1500 users, need HA in primary data center and DR also. looking for HA and DR solution for persistent chat server and office web app server.
is below correct?
1. 2 persistent chat server in a pool of primary data center and 1 in DR. can this be reduced or any changes?
2. 2 Office web app server in a pool of primary data center and 1 in DR. can this be reduced or any changes?
also do i need HLB for both roles?

1) In Lync Server 2013, there are improvements in both high availability and disaster recovery:
High availability improvements: SQL Server mirroring is used to provide high availability for the Persistent Chat Server content database and Persistent Chat compliance database within a data center (in-site).
Disaster recovery improvements: Persistent Chat Server supports a stretched pool architecture that enables a single Persistent Chat Server pool to be stretched across two sites (that is, a single logical pool in the topology, with servers in the pool physically
located across two sites). SQL Server Log Shipping is used for cross-site disaster recovery.
For more information about high availability and disaster recovery, see
Configuring Persistent Chat Server for High Availability and Disaster Recovery in the Deployment documentation.
2) for HA & DR, you can 2 Office web app server in a pool of primary data center and 1 in DR. and You will need HLB for office web app servers

Office web apps server 2013 - launching search on loading page

Hello!
I use Office Web Apps Server 2013 for viewing documents on internal portal (it is not SharePoint, and documents is read only) with automatic generating links. Links are generated according instruction
on http://<OWA host>/op/generate.aspx (for example, http://<OWA host>/op/view.aspx?src=<path to file>).
I have some questions:
1) In some cases, when a document is openedI want
immediately start the search with some terms.
Can I give terms
to search in url params in generated url? For example, http://<OWA host>/op/view.aspx?src=<path to file>#search=<terms>?
Is there any other
way to run a search on page load?
2) I want to use multi-term search (when my search query is 'tame tamed taming', and
all individual words ('tame', 'tamed', 'taming')
are highlighted in document).
Is there a way to do it?
3)I want to use whole-word search (when my search query is'act', and words 'practice' or 'action' are not
highlighted in document).
Is there a way to do it?

Office web apps Server for Sharepoint 2013

Hello,
I used the following article to install office web apps server and hook it up to a test sharepoint server:
http://technet.microsoft.com/en-us/library/jj219455(v=office.15).aspx. The OWAS service was verified as working by loading:
https://owas.companyname.com/hosting/discovery
For the sharepoint configuration phase, the following commands were run on the sharepoint machine:
1) New-SPWOPIBinding -ServerName "owas.companyname.com" -- (owas.companyname.com) is the host name of the owas server)
2) Get-SPWOPIZone
3) Set-SPWOPIZone -zone "external-https"
However, office documents are still launching in the desktop office applications, not in the browser. Any ideas of what else I may need to do?
thanks,
Sherazad

Hi ,
According to your description, my understanding is that you fail to configure Office Web Apps for your SharePoint 2013.
How about run Get-SPWOPIZone? If you can get a result, it says that your SharePoint have connected with Office Web Apps.
Then you can run below command to change the zone to internal-https.
Set-SPWOPIZone -zone "internal-https"

Load-balancing and fail-over between web containers and EJB containers

When web components and EJB components are run in different OC4J instances, can we achieve load-balancing and fail-over between web containers and EJB containers?
null

It looks like there is clustering, but not loadbalancing available for rmi
from the rmi.xml configuration. The application will treat any ejbs on the
cluster as one-to-one look-ups. Orion will go out and get the first ejb
available on the cluster. See the docs on configuring rmi.xml (and also the
note below).
That is a kind-of failover, because if machine A goes down, and the
myotherAejbs.jar are on machine B too, orion will go out and get the bean
from machine B when it can't find machine A. But it doesn't go machine A
then machine B for each remote instance of the bean. You could also specify
the maximum number of instances of a bean, and as one machine gets "loaded",
orion would go to the next available machine...but that's not really
loadbalancing.
That is, you can set up your web-apps with ejbs, but let all of the ejbs be
remote="true" in the orion-application.xml file:
<?xml version="1.0"?>
<!DOCTYPE orion-application PUBLIC "-//Evermind//DTD J2EE Application
runtime 1.2//EN" "http://www.orionserver.com/dtds/orion-application.dtd">
<orion-application deployment-version="1.5.2">
<ejb-module remote="true" path="myotherAejbs.jar" />
<ejb-module remote="true" path="myotherBejbs.jar" />
<ejb-module remote="true" path="myotherCejbs.jar" />
&ltweb-module id="mysite" path="mysite.war" />
... other stuff ...
</orion-application>In the rmi.xml you would define your clustering:
<cluster host="230.0.0.1" id="123" password="123abc" port="9127"
username="cluster-user" />
Tag that is defined if the application is to be clustered. Used to set up
a local multicast cluster. A username and password used for the servers to
intercommunicate also needs to be specified.
host - The multicast host/ip to transmit and receive cluster data on. The
default is 230.0.0.1.
id - The id (number) of this cluster node to identify itself with in the
cluster. The default is based on local machine IP.
password - The password configured for cluster access. Needs to match that
of the other nodes in the cluster.
port - The port to transmit and receive cluster data on. The default is
9127.
username - The username configured for cluster access. Needs to match that
of the other nodes in the cluster.

Office Web Apps server for Lync DNS question

We are going to deploy an Office Web Apps server for our Lync 2013 clients, available internally and externally. We do not have a split-horizon DNS so it is not possible for wac.foo.com to have a different IP for internal vs. external clients. What is the
best setup for our scenario? It looks like we can only add one address in the Lync topology builder, so would it make sense to send everybody to the external wac.foo.com regardless of whether they are internal vs. external? Or is there a better option?
Thanks,
Matt

It might be easiest to use pin-point DNS. Create an internal zone called wac.foo.com with a blank A record that points to the internal IP address of the OWAS/WAC server. This way, wac.foo.com will resolve to the correct
internal address, but you're not setting up a split zone for the rest of foo.com.
This trick can come in handy for publishing other items without recreating the entire zone, it's a nice one to keep in your back pocket.
