I have some problems in my environment of OBIEE 11.1.1.7. ( On Linux )
I have tried some random ways to figure out but I thought to get help from experts as I am not expert in such environment.
Problem 1: ODBC Error comes up with opening Analytics page.

What I have done for to resolve this.
1 - Find out the underlying user In repository and unlock it.
Then I get this error.
Invalid Username and password.
Problem 2: Bi admistrator gives error right away.

What I have done for this problem.
Copy my tnsNames.ora files under the directories.
\MWHOME\Oracle_BI1\network\admin
and
\MWHOME\oracle_common\network\ADMIN
Edit: User.cmd file to put path of tnsNames.ora file.
Problem 3: I really don't know what to check with ODBC Connection. I don’t' know the password either

From where should I start?
These problems are taking my days because I am not very expert in such environment.
