I am facing DB connection problem on QV side.
At SQL Developer I can connect nicely with same credential. TNSnames.ora has this entry.
Microsoft OLE DB provide for Oracle -->
The listener of the oracle database is not available. That's what the error message means. Contact your local friendly database administrator. The error is not related at all to Qlikview.
I appreciate your suggestion. I contacted our DBA team
I am sorry for late reply.
