Can't get sticky load balancing to work

I'm really puzzled why sticky LB is not working for a simple case I'm trying. I have two simple JSP's, both registered (see web.xml and ias-web.xml below). I'm using lite session and set distributable to false. Just in case someone can tell by just looking at my session id if it's supposed to be sticky or not, it looks like following -
GXLiteSessionID-4818869464307751325
My two JSP's are also attached below, and they're pretty simple. A new session is supposed to be created in login page and clicking on the logout page invalidates the session.
What I see is that each request (whether login or logout) is randomly sent to any server. For example, if I go to login once, further request to login or logout (whether through refresh or by clicking on the link) is not necessarily sent to the same server.
Any idea what's missing in my setup? I've tried different types of load balancing (round robin, etc.) so I know that's not it.
Thanks a lot in advance.

Hi,
I think it's best to wait for sometime and check the behaviour of sticky load balancing for sometime, the reason being one or more of the following...
- Although sticky feature ensures that the component is run at a single server, when combined with load balancing and under heavy user loads, the load balancing takes place.
- If we rule out the previous case, then, the load balancing mechanism, especially, per component based or per server based, sends request by round robin technique initally(around 128 times or so) and then calculates the effeciency of the response time and then follows the per server based or per component based.
- Meanwhile please ensure that, you have enabled the Sticky LB option under Application using iASAT and please wait for sometime sending requests(probably 130 times) after which it's good to check the mechanism of the sticky bit technique. If it doesn't behaves as it has to then, please let me know and I can help you further on this.
Regards
RG

Sticky load balancing not working because of Address Translation

          This came up before - see below. I don't understand what the
          soltion is/was.
          WL Server puts it's ip address in the WebLogicSession cookie
          which is an internal address 192.168.201.41
          WL proxy knows WL Server only by an external address like 139.141.38.21. Since
          it does not know of any WLS with an IP
          address of 192.168.201.41, it round-robins the request instead
          of sending it to the primary WLS.
          Any help is much appreciated.

How to make IIS plug-in do STICKY load balancing

There are two classes of scalable services: pure and sticky. A pure service
is one where any instance of the application can respond to client requests.
A sticky service is one where a client sends its requests to the same
instance; those requests are not redirected to other instances.
It seems to me that weblogic IIS proxy plug-in does not support the sticky
load balancing.
Could someone give me some information on how to make the proxy sticky?
Is there configuration parameters for this?
Thanks,
-Lei

I set the cluster.
It seems to me that there is some problem with the Set-Cookie mechanism of
the plug-in.
Sometime it set the cookie in my browser, sometime it is not.
Even from the wlproxy.log, I could set something like
Fri Aug 03 17:56:12 2001 Hdrs to
client:[Set-Cookie]=[AribaNode=O2tII92qHlP2tpZjUV0m5ued1s6X028cUPu24QcGj1Q25
AE5VXOd!1782877802312707887!ltang.ariba.com!8001!7002; domain=ariba.com;
path=/]
But the cookie is not set in my browser, what might be wrong here?
Thanks,
-Lei

I do believe that this will not work since if clustering is not enabled, a
cookie will not be set on the browser that contains the primary and
secondary server.
You are specifying two different ports in your servers. You need to use
clustering in order to get this functionality with the plugin.Furthermore,
you will achieve fail-over.

I add the following in iisproxy.ini
# This file contains initialization name/value pairs
# for the IIS/WebLogic plug-in.
WebLogicCluster=ltang.ariba.com:8001,achu.ariba.com:7001
ConnectTimeoutSecs=20
ConnectRetrySecs=2
Debug=ALL
WLLogFile=c:\tmp\wlproxy.log
WlForwardPath=/test1
DynamicServerList=OFF
CookieName=AribaNode
I use SesssionServlet.java as an example
When I involk http://proxy/test1/SessionServlet, I always get 1
if I use
http://proxy/test1/SessionServlet:AribaNode=................................
I could see the session becomes sticky.
If I do not want to use URL rewriting, what should I do in order to makethe
session STICKY
for this example.

If you leave the CookieName untouched on the WebLogic side, then there
should be no reason to make the change in the plug-in.
But yes, you need to make sure the cookie names are the same.

Eric
"Mark Vaughn" <[email protected]> wrote in message

Actually, you also need to make sure you set the "CookieName" in theplugin.
That let's the plugin read the cookie set by WebLogic to determine
who
the
primary and secondary servers are for that session. Otherwise, theplugin
has no
way of knowing if you are establishing a new session or returning to
an
existing
one. The cookie will tell it if you have a current session and who
it
should
send you to for continuing that session, or failing that session
over.

You need to have clustering so that a cookie is sent back to the
client
that
contains information about where it's session is located.
Otherwise,
you
are just going to get round-robin each time.
You can refer to the following page for more information:

I run two standone (Admin server) weblogic servers on machine1
machine2.
Then I deploy application test.war on machine1 first, then onmachine2.
Should I make machine2 as a managed server and machine1 as an

Will this make the session sticky?

IPlanet sticky load balancing question

We have two iPlanet Application Servers v6.0 sp3 and two iPlanet
Enterprise Web servers v4.1. All machines are on the same domain name.
All machines point to the same LDAP server. The application has been
installed on both App servers. Clustering has been configured in the
App server Admin tool to be based upon system load. For non-sticky load
balancing, all works fine, and session information is carried over
properly. However, for sticky load balancing, hits going into either of
the Web servers do not always go back to the App server that first
started the session.
The online iPlanet documentation says it can be done, but we have found
differently. Has anybody else gotten this to work?
Thank you,
David Shade

Hi David,
With sticky load balancing enabled, when you execute the application first
time it will go to any kjs depending on your load banancing criteria which
you set (Round robin or server responce or whatever), this applies to only
for the first time when you send request, afterwords it will be executed in
that perticular KJS process only till that KJS is alive, whatever may be
your LoadB creteria.
You please kill that kjs and see, you will be able to see the failover.
Feel free to mail me for any further information.

Sticky load balancing without clustering?

I don't need any type of session replication. I just want to run two
          instances of Weblogic on one machine, one IP, two different ports.
          If I run a third instance of Weblogic for proxying on the same machine
          on yet another port, can I take advantage of the HttpClusterServlet's
          sticky load balancing capabilities if the two Weblogic instances I want
          to proxy between are not participating in a cluster?
          All we require is to have an IP & port that we can hit that will
          round-robin the HTTP requests between the two Weblogic instances, and
          send all subsequent HTTP requests with the same session to the same
          Weblogic instance it sent it to before. Can this work? Thanks in
          advance,

NAS 4.0sp6 - sticky load balancing

Hi,
Can anyone tell me if sticky load balancing is required/necessary in a
multi process (8 x kjs's) single threaded (each kjs has only one thread)
environment on one machine. We seem to be getting concurrent session
problems between kjs's.
Platform: Solaris 2.6, NAS 4.0sp6
Thanks in advance.

In general no, but it depends on how your application is written.
In your case, probably yes, but I am only guessing here.
Session is usually distributed through DSYNC and therefore is
serialisable. However, if certain programmers made their objects
non-seriable then they are forcing the sessions to be stored locally and
sticky will help with sending the requests back to the same engine to
get that session.
In your case, I wonder why you are only using 1 thread per kjs. I assume
your application code is not thread safe and therefore you made the
decision to run multiple kjs with single thread only. Following this, I
believe you might also have programmatically made your sessions
local/non ditributable (because of the thread safe issue), thus if this
is the case you probably will require sticky load balancing.

Sticky Load balancing

Does WLS 5.1 supports Sticky Load Balancing?
          Thank you.

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter the name of the crashed application or process in the Filter text field. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, look under User Diagnostic Reports (not "Diagnostic and Usage Messages") for crash reports related to the crashed process. The report name starts with the name of the process, and ends with ".crash". Select the most recent report and post the entire contents—the text, not a screenshot. I know the report is long. Please post all of it anyway.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

How can I get my web cam to work in Adobe Connect ?

This is actually an end user's question that I am having trouble answering to...
We use Adobe Connect to give online language classes, the end user is one of the students.
I cannot find the right Support answer to give him.
Problem:
My camera does not work when I connect to Adobe's rooms but camera works fine with other software.
Even though I suspected my old camera was working fine, yesterday I went ahead and bought a new camera.
I thought perhaps my webcam software may have been a problem, so I bought a different type camera with different software.
Even after removing all the old software, same result:
I surmised the problem might be caused by my firewall and security software, so once I tried changing the permissions for Adobe, and my Webcam, but that didn’t work.
Another time, I restarted my computer right before class and then turned off my firewall completely so there would be no interference but to no avail. I’m totally perplexed.
Isn’t there anyone else experiencing a similar problem?   Has anyone else found a solution?
I run Windows Vista with McAfee Internet Security Software. I always reboot the computer before class and open no other programs other than Google Chrome.
I now have a brand new Microsoft LifeCam Cinema Camera with LifeCam 3.5 Webcam Software.
I test my camera before going online. It always works fine.   Then I shut down the camera program and login into class.
When I “connect webcam” in the room, the light on my camera comes on (suggesting that it is ON), but only a black image is transmitted to the room.

Check to see if you have Google Voice installed. If so, remove it and see
if your problem vanishes. If not Google Voice, check to see if you have
any other communications software which interacts with your cam and
disable it. This was the problem I had with a similar problem on a Mac.

Thanks a lot Heyward for the swift reply !
I sent the advice out to the end user, but unfortunately this wasn't the
solution.
His reply is below :-
The default resolution of my new camera is already set at 640x360, but I
went ahead and tried several lower resolutions (e.g. 424x240; 320x240; and
160x120) but none worked in the room - camera still showed up as black
blank screen. Also, as far as I can tell, I don’t have the option of
adjusting the frame rate.
I started playing around with my Internet Security Settings to see if they
might be playing a role. So far, all to no avail.
Hmm...quite a tricky one - webcams always are - maybe if he can find a way
to adjust the frame rate (?).
He's going to fiddle about with the settings a bit more and see if
something does the trick.
If anyone has had a similar problem and found an ingenious solution,
please jot on a note on this thread.

How can I get iCloud to accept my working Apple ID and password

My Apple ID and password works for iTunes and App Store. I'm trying to set up iCloud on my iPhone and iPad but i keep getting an error message that reads unsupported ID. Apple ID must be in the form of email address (@me.com). I don't have a MobileMe account. How can I get iCloud to accept my working Apple ID and password?

I've also reset my password to my Apple ID. I still get the Unsupported ID and password.

Hello, so today I realized that my iPhone with iOS 6 is frozen on the music. I can get back to the home screen but I can't get the music player to work because its frozen on the w's and will not respond to touch. I would be grateful for any help on this.

Hi deamayfield,
Thanks for visiting Apple Support Communities.
If your Music app is unresponsive, try restarting/resetting your iPhone:

I just got a new itouch and i can't get imessage or facetime to work on my home network

I just got a new itouch 4 and i can't get imessage and facetime to work on my home wifi network (Airport Express). I can't explain it. The itouch works fine otherwise uncluding the internet. Facetime and imessage work at the apple store so there must be something wrong with my home network. Please help if you can!
iPod touch, iOS 5.0.1

I changed the DNS to 8.8.8.8 as you suggested with no success, I even tried 8.8.8.8, 8.8.4.4 as suggested by others with no success either. When I try and activate iMessage or Facetime, I still get the same message "could not sign in, please check your network connection". The internet and Mail work perfectly fine on the iPod touch so the WiFi signal IS going through. I am at a loss, any other suggestions would be more than welcome. Thanks!
