Okay, long time no see! I am back. First of all, let me wish you all a Happy and Prosperous New year. Lets hope for the best.

I had some project , as well as, some personal commitments that I needed to complete during last year. One of my project commitment was, obviously due to the reason that I moved to a new project. Also, coincidently I moved to a new location in another country which added some more complications with my new project assignment…

I had a goal last year (2007) to become a certified PMP. PMP is an acronym for Project Management Professional offered by PMI (Project Management Institute). I took the training from Hexavarsity starting of the year. And eventually I have become PMP after spending quite a considerable time. That was my personal commitment that delayed me from writing in this blog.. So, long story short, I am going to write again in this blog. All that I know about Peoplesoft and Unix (Dont laugh, I will try!).

Lets start! We had a situation recently with our UAT environment. The “download to Excel” button is not working. You should be aware of what this “Download to Excel” button I am talking about. For those who are unable to guess, here it is. It is a small image, just like an excel sheet, that will be shown on the right corner of the any tabular output from Peoplesoft application ( Example Process monitor, Reports etc). If you click on this image, you will receive the excel sheet of whatever data you were looking at…

We started doing some research on this issue(still doing!). You know where to start first. You guessed, right, Peoplesoft Customer Connection. They recommended to try disabling JoltPooling in Web Server. This directive is available in web.xml file for the weblogic web server, and called Jolt Session Pooling.

Starting with Tools 8.48, Jolt Session Pooling is enabled by default. What does this mean? Let me explain this from the scratch. As you are aware, web server makes a connection to app server using Jolt. If you enable Jolt Session Pooling , the user connections between web server and app server are simply shared. This setting is expected to minimise system resources by sharing the user connection by pooled sessions…

Web.xml file is an xml file that has directives for all the peoplesoft servlets that the web server uses ( for example, psp, psc etc). Every servlet is set to JoltPooling set as true by default starting with Peopletools Version 8.48. All we did was, disabled JoltPooling on all of these servlets. And this issue is resolved.

Is the issue really resolved? Not exactly, I will say. We still need to find why Jolt Session Pooling needs to be disabled to make “Download to Excel” button to work. Mystery continues…. Until next time. – Vijay Chinnasamy PMP
