after going thru various documents here what i understood is that in the latest release of OBI i.e. 'Oracle Business Intelligence Applications 11g Release 1 (184.108.40.206)' Oracle is no more supporting Informatica and DAC configuration but it's replaced by ODI and ODI studio.
Oracle is supporting informatica in N-1 version which is 'Oracle Business Intelligence Applications Version 220.127.116.11'.
I understand if we go with latest version there may not be much help available for installation, configurations and may be known and unknown bugs.
Request experts if you could please confirm this? and what will be the best decision to go with 18.104.22.168 or 22.214.171.124 version??
