InfoView Business Objects 11.5

[BobMarley]

Hello

I installed BO WCA on two webservers. The web servers have a load balanced web address. WHen accessing this and logging onto infoview I am able to get in. As soon as I click the Public Folders button I get and error in the left pane where the folder structure is.

"en"); styleSheet();

An error has occurred: An unknown error has occurred.

The wca is installed on WIndows 2003 Server Edition Standard. Business Objects site is set to use 2.0 net framework.

This does not occur when I access each indivual web server.

Please help.

Sometimes it throws this error as well

Are you using the .NET or Java version of Infoview? Are you accessing the load-balanced Infoview through an IP address or a name? I suspect you're using an IP address. If you can set up a dns entry where the name of the site directs to the IP of the load balancer and then set up the name of the site in IIS on the server with the server-specific IP, that may help.

Also, AFAIK, the .NET version of Infoview uses session information that is stored on the server. This causes problems when the load balancer then moves the user to the other server.

FYI, quoted from the manual for the SA410 - Design and Deploy an Application class:

"Web farms are not currently supportd by BusinessObjects Enterprise. However, that is not to say that they won't work together. Some customers have successfully deployed using web farms, but it is not a scenario that is tested during the QA cycle, as a web server is not required as part of a BusinessObjects Enterprise deployment. For Java environments specifically, there are no known issues with the use of any web server proxy components that are supports by the application server vendor or provider.

"Note: For proxy load balancing, just as with hardware-based load balancing, the use of sticky sessions is required."

I am using hardware load balance web servers.
THis is also using .net infoview.


They configured port 80 to have sticky sessions and I am still having an issue.
