WebAnalysis blank applet
At times after fresh install of BI+, you might hit this error in the java console and you will get a blank applet when you launch WebAnalysis. So to fix this restart BI+ services under services.msc and restart the oc4j components in sequence.
Stop FR, WS and WA oc4js
Start FR, WS and WA

Hi!!!! This is Stephen Rengan, did my schooling in St. Annes Matriculation HSC, then went ahead with my Bachelors degree with Computer Science in Crescent Engineering College, Anna University. This sums up 21 yeasrs of my life :D One open question is, still wondering whether all those years were spent useful or not? Very much debatable !!!
Had to move forward with IT Industry, spent 1.5 years in Bangalore HCL, then moved to Oracle Hyderabad. Worked for 1.5 years there in Hyd, such a good place. Got internal transfer to a new Team in Oracle Bangalore.
