N.B:- Be aware of the joker type error message thrown here during my first installation as “INST-08029 Unable to connect to Database with given credentials.” It seems to be an Oracle BUG .See the issue in screenshot .
The reason of this error is the BIPLATFORM schema password .In RCU utility if you provide the password same as Schema name it would be creating trouble. Not sure whether it doesn’t accept the same password or it doesn’t accept the underscore(‘_’) character .I have not investigate further on it
Anyway I get rid of it after dropping the RCU schema for BI and recreate the same with password as‘rcu’ .This password has been provided here .
