Two RD SH collections – RD CB load balancing 2012 R2

I have created two RD SH collections, because some applications are only available through on SH collections.
How will that effect RD CB load balancing of RD SH servers regarding common applications, not specific one, based on RemotApp programs.
I did not deploy any DNS RR for RD SH. But I did deploy NLB for RD Web and RD CB.

Hi,
Thank you for posting in Windows Server Forum.
Can you specify some more description regarding your case as actually what you want to perform?
From your description seems you have installed one application as RemoteApp on both RDSH collections and you want that how they can be differentiated. If misunderstood then please correct. If that’s the case as described then you can assign the specific app
of particular collection to the user whom you want. There is facility to assign RemoteApp user assignment and by that way the user can access\see the RemoteApp on RD Web access page.
More information.

In addition you can go through this article for configuring and load balancing session collections.
Hope it helps!

Load Balancing 2012 R2 Session Host Collection with External Network Load Balancer

Hi,
We are moving from a 2008 R2 Remote Desktop session host deployment to 2012 R2. Previously, we used our Kemp hardware load balancer to distribute load between RDSH servers. We had a connection broker deployed so that if an existing disconnected session was
detected during the initial connection, the user was directed back to that session.
In 2012 R2, we planned to again used the Kemp load balancer to main high availability for our RDSH collection, but are experiencing strange issues. It seems that the RD Connection Broker is also performing load balancing--the result being that initial connections
to the RDSH collection may go to one RDSH server with the least connections through the Kemp, but then be redirected to a different RDSH server by the broker, even when there is no existing session for the user on that second server.
Our question is: Should we not be using the Kemp balancer at all (how would this work)? Or should we disable load balancing by the connection broker (if so...how)?
Further complicating our redirection issue with that the RDSH servers have multiple interfaces--one with public addresses and others with private. The connection broker seems to abritrarily pick among the destination RDSH server's available IP addresses
for the redirection and trying to redirect to a private address will fail. We think we have worked around this by connecting to each RDSH server from a 2008 R2 server's RDSH Configuration console and choosing just the public adapter under the Network Adapters
tab--is there no way to access this setting in 2012 R2?
Thanks in advance!
Matthew

Hi Matthew,
As you are most likely already aware, inn Remote Desktop Services 2012 / R2 the Connection broker uses round robin DNS to load balance.
To simplify things I would recommend that you let the connection broker load balance the sessions and use the KEMP to Load balance the RDweb and Gateway servers.
Have a look at the following articles:

Two 2911 routers and 3560 switches (load balancing and redundancy)

Good day, Sir !
I have a model with hierarchical model. Two routers 2911 and two core switches 3560, two providers.
I want to design redundancy scheme. Can you advice me how is better to do it ? here you can find image with topology, can you say is it good idea to connect with devices in this way ?
Hope on you help ! Thank you !!!

Hi,
If you want to configure redundancy in your network on LAN you can use HSRP and from the WAN side depending on the connection with the provider you can either use BGP or any IGP.
If you want to have load balancing as well with redundancy you can define differnt HSRP group for different vlan and on the wan with BGP you can use multipath option or with IGP you can manipulate the route matric.
Thanks & Regards

Reverse Proxy and Load Balancer for SMP 2.3 and Agentry Application

Hi Expert,
I'm putting in place a mobile solution composed by SMP 2.3 SPS 4 and SAP ECC 6.0. In the SMP 2.3 I created the agentry server and I have deployed my agentry application.
My SMP/Agentry infrastructure is composed by two servers therefore I need a load balancer for balance the load into the several servers. Furthermore I need to use a reverse proxy in my DMZ zone.
Based on what indicated in the SAP note "1904213 - SAP Mobile Platform Server Release Information" the Apache Reverse Proxy is not supported for Agentry clients. Agentry uses nginx for Reverse Proxy.
I also found the following document How-to-Guide for Reverse Proxy and Load Balancing in SAP Mobile Platform 3.x that explain how to set-up a reverse proxy and load balancer with nginx and apache.
Both the SAP note and the HOW to document are refereed to SMP 3.0 and not to SMP 2.3.
I would know if the NGINX must be used also for SMP 2.3.
Any suggestion/information is appreciated.
Thanks in advance

Does SLS support load balancing services?

Does SLS allow for load balancing of services? Such as iChat, Address Book, Calendar, Mail, Web, etc?
Right now I have four Mac Mini servers
Mac Mini 1 - Primary DNS, Open Directory Primary
Mac Mini 2 - Primary DNS, Open Directory Replicate
Mac Mini 3 - VPN, Mobile Access, File Sharing, Software Update Services, Address Book, iCal, and iChat.
Mac Mini 4 - Web / Mail
I want to get two more mac mini's to load balance #3 and #4. Meaning, if the server goes down or gets heavy load, it will start utilizing the other mac mini.
How can I set this up??

As for load balancing iAS has a component called Web-Cache which can be used for this.
For installation of iAS as per the OS you will find information at the folowing link:

Session based load balance + Prepared statements

Experts,
From the docs I understand that there are 3 load balancing techniques. One is client side and two are server side. Of the two, one is session count based load balancing, and as per docs, it is recommended for connection pool setting.
My question is if I have prepared statements originally created using connection to node1, and say if listener re-directs the conneciton to another node node2, will the prepared statement work on node2 ?.
Thanks
Vissu

Just to clarify, the question is:
Are the prepared statements usable when we use session count based load balancing.

CSS load balancing problem

Hi,
I have two CSS that I use to load balance RDP connections to two WTS servers. I dont have switch behind CSS so they are connected back-to-back via cable. All server facing ports (including back-to-back ports) are in the same VLAN.
CSS1 is primary for the VIP address and for redundant interface address, and CSS2 is standby.
So, when I connect WTS-1 to CSS-1 and WTS-2 to CSS-2, CSS1 sees both services as active and everything seems fine. If WTS-2 is disconnected, WTS2 service on CSS1 is down etc.
In sticky table, I can see that CSS1 is load balancing request to both servers, but the problem is that only RDP connections to WTS-1(server directly connected to CSS1) work fine , and connections that are load balanced to WTS-2 are dropped??? Direct RDP connection to WTS-2 IP works fine.
If I connect WTS-2 to CSS1, so both WTS servers are connected to CSS1 everything works fine.
Can anyone tell what can be wrong?
Configurations are in the attachment.
Thanks for help.
Regards,
Branimir

try the command 'ip uncond' on both CSS.
It will guarantees that the response from WTS-2 comes back to CSS1.

Load balancing problem with CSS11503

Hello all,
We have two web servers that are being load balanced with this configuration on two CSS11503 with IOS version 7.20 Build 206;
content Web
add service web1
add service web2
vip address 10.1.4.4
protocol tcp
port 80
url "/*"
advanced-balance sticky-srcip-dstport
active
When we try and access the web servers from client workstation using the URL on Internet explorer 6.0 and get authenticated through the login window; we get error 12031. Error 12031 means " ERROR_INTERNET_CONNECTION_RESET The connection with the server has been reset. "
On refresh the error goes away.
If we bypass the content switches by accessing any of the servers using server name; the error does not appear. The problem seems to be related to the load balancing.
Any suggestions?

the problem is probably due to CSS sending an HTTP redirect with the RESET flag when you send multiple request inside the same connection.
To avoid the proble, do a 'no url' under your content rule.
There is absolutely no need to specify the url since you do stickyness based on source ip address.
Regards,
Gilles.

An 881 should be able to load share across multiple ports. Many routing protocol support ECMP, including BGP, but you need "special" hidden/secret commands to enable. EIGRP also supports unequal cost load sharing.
If an 881 supports OER or PfR, those too will do unequal load sharing, dynamically.

Network Load Balancing - Multicast IPv6

I have a two servers with network load balancing. They are configured to use IGMP Multicast which works well with IPv4. The switch correctly detects the group and sends the traffic to only the ports connected to the servers.
However i can't get IPv6 working outside of the servers subnet. You can access the loadbalanced IPv6 address from within the servers subnet but machines outside the subnet cannot access it.
Does load balancing properly support IPv6? Should it not support Multicast Listerner Discovery (MLD) to work properly with IPv6?
Thanks

Thanks for your reply.
Yes - you are correct. We are using an IPv6 address as the cluster IP address for incoming connections but it can't be access outside of the subnet. The cluster has both a link-local and global address - both are only accessible from within the subnet.
The two servers that are part of load balancing cluster both have IPv6 address assigned to their network adapters - these are accesible outside the subnet. Infact 80% of all our network traffic is IPv6 - routing is working fine between all servers, workstations
and devices on our various subnets. The problem is purley affecting the load balancing IPv6 address.
The IP config and route tables are below. Thanks for your help.

ARFC: Single Server and Load Balancing

Hi All,
I am trying to create aRFC model. In SAP logon screen, I can see two tab pages - Single Server and Load Balancing.
Can you please let me know when we have to use which tab?
Thanks
TG

Single Server Connect or Load Balancing connect is completely independend from the location where SAP Gui Client is installed.
Single Server connect means that your are directly connecting to an ABAP Server using hostname and systemnumber you have to provide.
Load Balancing Connect means that you specify the message server of the central instance of an ABAP Server group. The SAPGUI first connects to the message server which will provide the SAPGUI with the information about the best performing ABAP server. SAPGUI will then connect to this ABAP server.
Single Server is suitable for small landscapes with lets say less than 4 application servers. In huger configurations (and those which I know will grow to more than 3 servers)I would prefer to use logon groups - aka Load Balancing.

Load Balance guest Internet access via two different DMZ zones at two sites

Hi Sir,
My customer has the following unified wireless guest access requirement:
- There are 2 internet links and dmz zones at two different locations, Site A and Site B
- Data centre is at Site A
- WiSM is proposed to be installed at the Cat 6500 in Site A
- Lightweight AP are distributed across Site A, Site B and other branches
- Only one anchor WLC is proposed at Site A, DMZ zone to provide guest internet access
My customer would like to load balance the guest via the two internet link at Site A and Site B but with the same SSID across all locations. Can it be done since only one anchor at Site A? How about puttting another anchor WLC at Site B, DMZ zone? But how can i establish two EoIP tunnel to two different anchor WLC from a single WiSM?
Thanks for your help
Delon

You can... but you can't control where the traffic will flow. The wlc will determine which DMZ wlc it will use. The wlc will load balance, but traffic in site A might go to site B. I currently have deployed that senerio in multiple client installations....

Load balancing host named site collection

I am jumping into the realm of host named site collection. While the learning experience has been good, still there are some questions unanswered. Please bare patience since my questions are long.
- I have a non host header site on port 80 that has https certificate added to IIS for supporting app store in https mode.
- I tried to created the host name site collection using https in this default port 80 non host header web application and was greeted with error. Then i extended the web app to different zone with port 443 . Then created the host header site collection
with https with web application name for extended 443 one. Creation went in fine.
- I tired to use IPs on now extended IIS site and bind certificates on that one. The site does not load. I do the same again in the default zone iss site, bind ips on that one and site loads. Now question is even though host header site collection was created
using extended web application url , why binding had to be done on default zone IIS site?
- Second test, i changed the authentication mode for extended, no effect on host named site collection but as soon as i changed it in default zone it reflected in host named site collection. I am confused why it needs extended zone url to create the https
site but every change done in default zone is getting reflected on this host named site collection.
Now for load balancing , it works fine with IP? But how to load balance these host named site collection using url. I talked with f5 team and they said i need to send some reply query string from each site. Where do i do that? Or is it even needed?
Accoring to this link : https://devcentral.f5.com/articles/name-based-virtual-hosting-with-ltm
. If the site hosts an application, though, the monitor should request a dynamic page on each webserver which forces a transaction with the application to verify its health and returns a specific phrase upon success.
For application monitoring, the recommended best practice is to create such a script specific to your application, configure the monitor Send string to call that script, and set the Receive string to match that phrase.
Has any one done this before? I tired to search for resource regarding this for iis or sharepoint but was not able to get anything.
Thank you for your patience for reading such a long question.
Adit

first part of question:
Default Web Appliction in port 80: Creating https host named site collection fails.
Extend default web application on port 443 : Https hostnamed site collection created when web application name is passed for extended web application on port 443. This means this site collection is associated with this extended web application correct? But
all the changes made in IIS only reflect if it is made to port 80 web application. Also changing authentication scheme from Central Admin, only changes on default zone reflects on site collection not the one in extended web application? Why if the site
was only created on extended web application paremeter, changes on default are reflecting on it but not from extended.
Second part of question:
Each Hostnamed site collection when load balanced thorough f5 using IP for 3 WFE uses 3 IPs for each. This way we will run out of IPs pretty soon. I want to know if there is way to load balance these sites using Hostname or anyother paramenter through f5
and if any body has done it?
https://devcentral.f5.com/articles/name-based-virtual-hosting-with-ltm link talks about sending reply string
from application but i do not know where to set it up or how to do it? No resources in the net. Just asking if any one else has done it.

Error while load balancing two servers

i have two Solaris servers running 9iAS R2 OC4j.
current patch level is 9.0.2.3
i'm trying to load balance the instances according
to the instructions in this document:
Oracle9i Application Server: mod_oc4j Technical Overview
all i should need to do is run the command:
dcmctl addOPMNLink <IP>:<PORT>
but when i do this i get this error:
ADMN-906026
i could not find any info on this error with searches of:
Google, Google Groups, Oracle MetaLink, Oracle OTN.
ideas? suggestions? anything?
thanks,
.rich

i just tried running a "dcmctl getError", and got this:
ADMN-906026
This Oracle9iAS instance is currently using a database repository to store configuration information. The OPMN link functionality is not supported when a database repository is being used. An Oracle9iAS cluster should be created to associate Oracle9iAS instances when using a repository.
the two OC4J instances in question are associated with an Infrastructure instance on their respective servers. do i need to de-couple the OC4J instances? or create a "cluster of one" instance?
