A: Much of the configuration of OBI that used to be done in the NQSConfig.ini files can now be done using this front end console, which in turns updates the NQSConfig.ini file. Things in the NQSConfig.ini file that are set by EM are noted in the file with '# This Configuration setting is managed by Oracle Business Intelligence Enterprise Manager'. Some things that needs to be setup manually in the NQSConfig.ini file are:
1. Usage Tracking
2. Dynamic Libraries
3. Query Optimization Flags
4. MDX Member Name Cache Section (SAP BW)
5. More specific General Settings where EM doesn't contain the level of detail required D: Cache Management Techniques include
