How to do
To achieve it, you have to unmark the check box “Shared Logon” of the connection pool property in the physical layer. You can remark that the user and password box become gray.
Now, the Obiee users don't share no the same credential and you have to define for each Obiee user, one credential (one username, one password).
To define the new credentials :
- open the Oracle BI Administration tool
- open the security manager (Manage> Security)
- click on the user map
- double click on a user
- define in the tab logon the user credential for your database
