    Oracle data connection error - 12154

    Alan Kwan

      Hi all,


      I just upgraded from XP to win7, so I had to configure my oracle connections again.


      Here are the things I have done:


      1) I have set up the system variable as defined by this doc:



      2) I have set up the TNSNames.ora with the oracle server I am trying to connected to, in fact I even copied the full text from another machine that is successfully connected to the data source.


      3) Restarted my computer


      4) Even installed the oracle 8.0 driver


      but I am still getting the ORA-12154 error!!! Anyone has any thoughts on this?
