We have SIA installation on one server and tomcat installed on other sever.
We have upgraded SIA to new version by running setup.
Do we have to also run same installation on other server which is having Tomcat for upgradation.or is it not required
If you originally installed Tomcat on your web server from the Business Objects installation media, then you should certainly run the upgrade on your Tomcat server.
If you installed your own version of Tomcat, I would check to make sure it is the latest version that is supported by your version of Business Objects and upgrade it to that version.
If you installed your own version of Tomcat, don’t forget to redeploy your Business Objects Web Apps to update them on the Tomcat server.
