Yes, you need to apply those steps. ATGLite is a J2EE component which is used by BIACM. During the install BIApps RCU you might have defined the user BIAPPS_BIACOMP these will be used in ODI and for updating the BIACOMP schema
After I did following steps
3.3.5 Updating ATG Lite
3.3.6 Updating FSM
I went to next step which is: use configuration utility to extend the Oracle BI Domain, I get below error message
INST-08068: ATG Repository Might be corrupted Error.
after I enter 'BIACOMP' schema details. Anybody faced this problem?
