无法用python的cx_Oracle连接oracle远程数据库

Question

I issue this statement: db = cx_Oracle.connect("user/pass@IP/BKTDW")

and I get this error: Traceback (most recent call last): File "", line 1, in cx_Oracle.DatabaseError: Error while trying to retrieve text for error ORA-01804

It seems that connect method doen't work at all. I have installed the Oracle Client and I am connecting normally via Toad or Sql Developer.

Please Help!

Answer 1

I had to set the ORACLE_HOME variable in the system variables and also add the bin directory in the PATH system variable. THNX

Answer 2

Ensure that sqlplus is working from cmd line. It could be if on 64bit windows in has in PATH there is a target to non-64 bin version of oracle bin folder. In our case we ensured that 64bit location is placed in PATH . For instance place c:\\Oracle\\Ora11g_r2_x64\\bin\\ and remove c:\\Oracle\\ora11g_2\\bin\\ , it was not related with ORACLE_HOME .
