Answer 1

Hi Kranthi,
Here are my responses:
1) I am working on only one database but different RPD's according to my requirement im building it.When i write it into answers as different sheets and saving >them into my folders catalog.
To see the saved work also is it neccessary to have multiple presentation layer,multiple RPD on single servers??Explain me on this??Response: Each presentation server can only communicate with 1 RPD. They use an ODBC connection (AnalyticsWeb is that system DSN ODBCconnection) to communicate to that RPD via the BI Server. By default, the Presentation server communicates with the default repository. You have to override this default behavior if you want a different user experience.
So right now, you only have 1 active RPD at a time, which is the one that is the "Default". Unless you setup multiple system DSN's and multiple presentation services, you'll be stuck in the position you are where if you want to run Report A from repository 1, then Repository 1 has to be the active repository.
2)If we want to see saved sheet in answers,is it must we should set the concerned RPD to default??Response: I kind of covered this a little bit in my last response, but yes. By default, OBIEE on install only sets up a single System DSN connection called AnalyticsWeb. This connection, by default, connects to the default RPD. It is the only way for a Presentation Server to communicate to the RPD. So if you only have 1 System DSN defined at a time, then you have to always have that RPD be the default so the Presentation Server can communicate with it. Otherwise, you'll need to setup additional System DSN's (1 for each RPD). See the link I posted in my last message on how to set that up.
3) if i have more than 10 RPD's in same database,should i change this these many times??Response: There is no limit to how many RPD's or presentation servers you can have on a single install of OBIEE. That being said, as a best practice I would recommend not going past the 5 you already have. Instead of having multiple RPDs against the same sources, you should make different BMM layers in OBIEE using the same RPD. This will reduce redundant physical connections across the RPDs. You can also setup a projects and a multi-user development (MUD) environment on a single RPD that has multiple BMM folders.
4)Im the administrator user and im developing reports.For me only this issue is coming up.What about when i give access to other members??Response: If you continue your development as is, users will only be able to access reports against the live or "Default" RPD. All other reports you are creating will give errors similar to the title of this post. This is why I would further recommend that you consolidate your RPDs into a single file.
Why did you originally create 5 RPDs? What was the business requirement behind that?
Thanks!
