Re: Midtier Loadbalancer is not working - Any suggestion ? - URGENT
Hi John, Thanks for your help.. I tried with changing the default web path (in ar.cfg file ) for all the ARS servers. I am able to login to 2 Individual MT servers but still i can login to MT Load Balancer. When I am opening the URL through browser, the Login Page appears for MT Load Balancer, but there not able to login and can't view any pages. It will be very nice, if you or anybody put some thoughts on it.

Re: Midtier Loadbalancer is not working - Any suggestion ? - URGENT
Just to be clear You can login if you go direct to the MidTier web server http://MTweb1/ars/... You put into your web browser http://LBweb/ars/... The load balancer forwards the request over to the MidTier web server 1 http://MTweb1/ars/... What does the URL in your browser show? Also, What OS are your web servers (and MidTier on)?

This doesn't seem to be clear. Are you saying the URL in the browser changes? Have you got the AR System 'default web path' pointing at the load balancer hostname; you can find this in the ar.cfg file. Have you got the LB sticky bit set? Mid Tier does not cluster and replicate sessions, so there is no active/active configuration hence sticky is required.

Re: Midtier Loadbalancer is not working - Any suggestion ? - URGENT
Ziyan, So, for testing purposes, shut down one of your Mid-tiersthis will allow you to properly know which of your mid-tiers your LB is pointing you atthen go into your remaining online server and turn on logging in the mid-tier and see what sort of logs come on regarding logins when you try to authenticate This will at least be a start. -Original Message- From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of syed Ziyan Sent: Tuesday, January 29, 2013 11:18 AM To: arslist@ARSLIST.ORG Subject: Re: Midtier Loadbalancer is not working - Any suggestion ? - URGENT ** Hi John, Thanks for your help..

Re: Midtier Loadbalancer is not working - Any suggestion ? - URGENT
Seems like your session affinity or sticky bit not working correctly so it is doing a round robin for each web call. I am guessing your are getting routed to one midtier, you login there redirected to a new url , the next reroute is going to another midtier since that midtier did not have authentication it is asking for login again. As LJ mentioned turn off one off extra midtier and ARS and run with only one ARS and MT and see if you can login now. Also you could add in your /etc/hosts file on you midtier to map LB alias to local IP that way once LB routes to a server it stays there for that entire transaction. ___ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org "Where the Answers Are, and have been for 20 years"

Hi Pat, Thanks for you help... I have done the changes in hosts file and also tested with turning off one WS. still the issue remains. Please suggest any other possible solution.

Re: Midtier Loadbalancer is not working - Any suggestion ? - URGENT
Can you try with just one ARS and one MT using MT LB. MT LB --> MT1 --> ARS LB --> ARS1 What is you LB vendor F5 or Cisco ? Also after you make changes to /etc/hosts file you either need to reboot the linux server or restart the network services to have the change take effect.

Re: Midtier Loadbalancer is not working - Any suggestion ? - URGENT - Resolved.
Thanks Fred John and others who provided their help and suggestions. Finally the issue was resolved. We have added the entry in all hosts file as well as Infra team has changed it to sticky session at LB end.
