What is the default location of a repository file?2. How many repository files can be loaded to a BI Server simultaneously? Assume its a singleserver with single instance of BI Server running just to keep things easy3. If you have more than 3 repository files mentioned in your NQSConfig.ini file as default,which one gets loaded to the memory when the BI Server is started?Ex:Star = SamplerRepository1.rpd, DEFAULT;Star = SamplerRepository2.rpd, DEFAULT;Star = SamplerRepository3.rpd, DEFAULT;4. How do you import Essbase Cubes into your repository?5. Whats XMLA and where is it used for in OBIEE context?6. Can you change the location of your rpd file in your OBIEE Configuration? If Yes, Wherewould you mention the new location of this rpd file for Bi Server? Instance conifg.xml7. What kind of joins would you perform in the physical layer of the repository file whenopened with Administration tool? Physical join8. What are the minimum services needed to load a repository file onto memory and view adashboard which has reports that have been refreshed on a scheduled basis? Bi scheduler, bipresentation services, bi server9. Can you use an OLTP backend database for creating a dashboard?
10. How many tables are needed in minimum to pass through the Consistency Checking inLogical Layer (Business Mapping and Modeling Layer) of the repository? 1 fact 1 dimension11. Can you create new views in the database using OBIEE Administration tool? Can you explainthe procedure for doing this? yes12. What is a complex join in OBIEE and why, where is it used? 1to n or 0,1 to n13. Is it mandatory to have hierarchies defined in your repository? If Yes, where does it help? IfNo, what happens in the reports? Drill down14. How do you create outer joins in physical layer? BMM Complex join15. What does Consistency Checking perform; What are the minimum criteria to passconsistency checking for a given repository?16. Does OBIEE store physical sql ? How is physical sql generated in OBIEE environments?Administrator or C:OracleBIserverLog17.

Where does the BI Server logs its start, stop and restart times in the file system? BIserverlog22. You have two tables Table 1 and Table 2 joined by a foreign key in the database? They areimported together from the database into your physical layer. Is this relationship still preservedin the OBIEE physical layer?
23. Same as question 22 but what happens if you import each table seperately?24. If Table 1 and Table 2 are dragged from physical layer to BMM layer, which table becomes aFact Table and which table becomes a Dimension Table? 2 tables act as fact25. What if the tables (Table 1 and Table 2) are not joined, then what happens in BMM layer?26. What is the difference between logical table and logical table source?27.
