SAP BI4.2 upgrade

Hi,

I have a one node deployment with the bobj servers running on a machine. However, the web tier(tom cat) was installed on a different server.We have to upgrade the environment from 4.1 sp3 to 4.2 sp3. I have couple of questions-

1. Is it a best practice to run the Tomcat using a service account as well or should I leave it to run under local account?

2. For the upgrade , should I first do a custom install on the main node( with cms and other bobj servers) and then run a web tier install on the other machine( which has tom cat running)? Is this the best way to do it?

Thanks

As to answer your question, ideally its a good idea to run your SIA and services using a service account.

it's mandatory when you have to do some extra configuration like setting up windows or sap authentication. Or when you have to move input/output folders on network location.in all such activities you need a service account.

First you need to do upgrade on main node(Cms node) and then on web tier.

Make sure you take a backup of any custom configurationfiles if performed on server.like any change in image folder or web.xml files or any in custom folder. Upgrade will overwrite these changes and you need to do again.

Question 1: if you need to configure BI4.2 SSO (Single Sign On), then you must start Tomcat using service account.

Question 2: For Bi4.2 upgrade, you can run custom installation on CMS server node. (CS and other application nodes.). But i strong suggest you also install web component. You can choose not start TOmcat on CMS nodes. But it always good to keep web component binary files on CMS node. Regarding Tomcat upgrade, I assume you run directly upgrade from BI4.1 to BI4.2. In such situation, Please do un-deploy all BI4.1 web components from Bi4.1 Tomcat server nodes before you run Bi4.2 upgrade. BI4.2 will comes with tomcat 8 and BI4.1 comes with Tomcat 7. Be careful with tomcat upgrade as well. after you upgrae BI4.1 tomcat node to BI4.2, deploy Bi4.2 web component to tomcat again.

If you're doing an upgrade and not a full install, you don't need to do a custom install. The upgrade install will upgrade all of the things that you have installed on each server.
