WLC 4404 - Clearing the Load Balancing Statistics?
Does anyone know of a way to clear the load balancing statistics from a WLC 4404? I've looked through the gui and CLI and can't seem to find a way to do it.
Thanks,
Rob
You can do a 'show summary' to see the number of connections that have been sent to each servers.
You can't see the number of bytes so.
I would suggest to collect this info on the server.

Site not accessible from the Load balanced web front end server - sharepoint 2010
I have a production environment with 2 WFE's(sp-wfe1 & sp-wfe2), 2 APP's and 2 SQL clustered VM's.
2 WFE's are load balanced using hardware load balancer.
An A-Record(PORTAL) is created in DNS for the virtual IP of the load balancer which points to the 2 WFE's.
A web application is created on the WFE's on port 80.
alternative access mapping is configured and the load balanced record "http://PORTAL" is used under the default zone.
Under IIS I have edited the bindings for the sharepoint site at port 80 and added the HOSTNAME as PORTAL.
Result: The site is accessible from outside the server and works fine.
ISSUE: The site is not accessible within the WFE's(sp-wfe1 & sp-wfe2).
When I browse the site from the WFE's server it ask for the credentials and when I enter the credentials and click OK it ask the credentials again and again and in the end displays a blank page.
Kindly help me in this issue because I am clueless and couldn't find anything helpful on the internet.

How to use the Load Balancer Plug-in to serve multiple domains
In SJSAS8.1 SE/EE the asadmin commands that create and maintain a load balancer configuration operate within a domain. When the load balancer configuration is exported an xml file is created that contains all the information for that domain. To make the load balancer plug-in balance the load for multiple domains, the loadbalancer.xml files can be manually merged to conatin the data that is exported from each domain's load balancer configuration.
For example, 2 domains are created, both having a load balancing configuration. After exporting both configurations using the asadmin export-http-lb-config command, the user would then cut and past the cluster information into the single loadbalancer.xml file that resides under the web server's config directory.
An example of the manually merged loadbalancer.xml file follows:
<?xml version="1.0" encoding="UTF-8"?>
<loadbalancer>
<cluster name="domain1">
<instance disable-timeout-in-minutes="30" enabled="true" listeners="http://localhost:1026 https://localhost:38181" name="i1"/>
<instance disable-timeout-in-minutes="30" enabled="true" listeners="http://localhost:1027 https://localhost:38182" name="i2"/>

How to get a server name through the load balancer
Hi.
I'd like to get the server name where is my application installed. There are some servers and clients access there throuth the load balancer. When I try to get it with request.getServerName(), I get the virtual address of the load balancer.
Any suggestions?
Thanks.Dear Sikindar;
THanks for your cooperation, but I believe that these Tcodes will eb helpful if I know the table name, actually we don't know its name and that's what I'm asking about, how can I get the table name for the ABAPer?
Appreciating your cooperation.

Web Dispatcher not doing the load balancing on the portal
Hi Experts
I am having a production issue where the SAP web dispatcher is not doing the load balancing on the portal.
We have ESS/MSS portal with 1 Message server and 2 Application servers. The Web dispatcher is installed on the message server itself. Here is my Web disp profile file

wdisp/enable_j2ee_groups = TRUE
wdisp/HTTPS/sticky_mask = 255.255.255.255
In my Web dispatcher Admin page, I see all the three application servers, however the requests are going to only 1 App server. We are using ENd to End SSL configuration for the web dispatcher.
We also have a reverse proxy in the landscape and reverse proxy is forwarding all the requests to the Web dispatcher. In Web disp Admin page>Dispatching Module>SSL End to END dispatching, I see only ONE table entry in the dispatching table and it is our Reverse Proxy.
As all the requests are coming from only one source (Reverse proxy), it seems to me that the sap web dispatcher is forwarding those to the same Application server every time.
Can anyone please advise ?
I also tried to configure logon group in NWA, the web dispatcher is detecting the logon group and all the app servers in the logon group. It still not doing the load balancing.
I would greatly appreciate any help.
Thanks
VinyVincent, can you please elaborate more ? Is the web dispatcher not able to recognize stateful and stateless application requests ?
I saw that the procedure for configuring SSL Termination on Web dispatcher is long and complicated and looks like SAP web dispatcher needs to have SSL certificate of its own. As we have no ABAP servers and only Java servers, I can not even create the PSEs using STRUST (as described in SAP help -http://help.sap.com/saphelp_nw70ehp1/helpdata/en/48/99c388d7c46bb9e10000000a42189d/frameset.htm
We already have SSL certificates for Java App servers.
I suppose there should be a way for web dispatcher to identify the incoming requests and forward to appropriate application servers.
Any help is much appreciated.
Thanks

The load balancer is not provisioned error when attempting to deploy a SP 2013 App
Hello:
I am in VS 2013 with SP 2013 colocated on same Win 2008 R2 server. I opened a SP 2013 App and directly hit F5 and got this error:
Error occurred in deployment step 'Install app for SharePoint': The load balancer is not provisioned. Verify the load balancer was provisioned successfully before retrieving endpoint addresses. When creating the project, the first screen asks for a
site to deploy to, and I just took the default, which was http://<servername> for the colocated server.
I googled this and could not find a solution. Would anyone have any direction?
thank you
Harvey
Regards, HarveyHi Harvey Flaisher,
Based on the error message, this seems to be a service application not working issue.
Please check the ULS log or Event log to check in which service application the error occurs, like BCS, secure store service, app management service, then re-provision the service application using PowerShell command, or re-create the service application
from UI to check the result.
Thanks,

ConnectionFactory - who does the load balancing
Consider creating a connectionfactory (with server affinity unticked, load balancing
ticked and using the message delivery policy of round robin) we then go on to
create a distributed domain targetted at the cluster of two managed server's (managed1
and managed2)
If I create a simple java app that put's messages to that distributed destination,
using the connectionfactory above, who's responsible for doing the load balancing.
Does the client create the session knowing that the connectionfactory requires
load balancing and thus takes the responsibility for it, or does the client just
put a constant stream of JMS messages to the WLS and the connectionfactory class
takes responsibility for the load balancing
Who maintain's the delivery state, the client application or WLS (i.e who's job
is it to look up the last messages queue destination?)
Hi Barry,
A JMS client's produced messages are first delivered to the WL server
that hosts the client's JMS connection. The JMS connection
host remains unchanged for the life of the connection.
Once produced messages arrive on the connection host,
they are load balanced to their JMS destination.
For more information I suggest reading the clustering
sections of the JMS Performance Guide white-paper. You can find
the white-paper here:
http://dev2dev.bea.com/technologies/jms/index.jsp

Call to the load-balanced SO not through router
Hi all
This in fact not correct - if you make a call to the load-balanced SO,
from within that SO it will not go through the router. You can work around
it quite easily
with a simple Forwarding Dispatcher (design pattern).
Whenever you make a call to your load-balanced SO,
it
would go through the router. That is what I
understand. No matter you make the call from inside
or outside the SO.

Hi, I just started using the SJWS7.0. When a client sends a request, is the request to the load balancer server name or the admin server name? Any information on how to use the load balancer will also be appreciated
The server where the load balancer is running. The admin server has not play in the load balancing beyond allowing you to configure and manage it using the administration console.

How the Load balancing happens in CPO
Hi All,
On what bases the process engine selects the process or request and how the load balancing happens.Hi!
I am a little confused by the question (as it refers to "request"), but I am going to assume that you are asking how a High Availability Process Orchestrator environment with several servers chooses which processes running on which server.
The answer to that question is...
In general, processes to be executed are split equally between all servers. The only piece of data being taken into account during process instance assignment is the current load on the servers (as counted by the number of top-level processes, not counting child processes). For example, suppose that there are 3 servers in the environment, and server A is running 5 top-level processes, servers B & C are running 3 top-level processes. When new process is started (e.g. on a schedule or manually or triggered via an external event), it will be assigned to either server B or server C for execution, because servers B & C have less load. If under the same circumstances (A:5, B:3, C:3), there are 4 processes started at the same time. When the work is distributed, the total expected work 5+3+3=11 (existing work) and 4 (new work) will be distributed equally with, with servers B&C each getting 2 new processes.
This is a general load balancing algorithms used by the servers in HA environment to decide which server runs which process instance.
There are other factors that come into play, as some processes/activities can only run on server A or server B for technical limitations (e.g. SAP work against a particular SAP System can only be executed from one server in the environment). When those come into play, the work may end up distributed unevenly.
Note that available memory, CPU load, or disk space on servers are not directly taken into account during load distribution. -
FDM keeps give me DCOM Security Error when I configure the Load Balance
Hello, everyone.
I installed FDM on the Windows 2008 Server.
When I configure the Load Balance Server for FDM.
It keeps give me error:
Unable to create Load Balance Manager Object!
Please verify that the user name, password, and domain name are correct.
However, I am pretty sure the user name and password input are correct.
I have tried the solution provides on Oracle Support. And changes the DCOM component's security settings.
However, the issue is still existed.If after clearning out the security on the DCOM object and attempting to reset the Load Balance Config the same issue occurs, you will need to un-install FDM using the EPM System Un-installer and reboot. Following the reboot you will then choose to install FDM again, configure FDM using the EPM System Configuration utility, and then reset the FDM configuration items.

SSL credentials forwarding by the load balancer
Hi,
Is it possible to send the client authentication to a real server ? The idea is to leave the ssl termination to the load balancer but do autentication on the (real) server. Thanks in advancenot possible.

We have a CSS 11050. We mostly use it for load balancing accross multiple web servers. What is the command to see some statistics on how much traffic is sent to each one of the web servers? (Number of bytes, connections...)
You can do a 'show summary' to see the number of connections that have been sent to each servers.
You can't see the number of bytes so.
I would suggest to collect this info on the server.
