Oracle Database Discussions

Hello.

I have enterprise linux 6, oracle SE 11.2, postgresql 8.4.

I try to set ODBC by this scenario: http://docs.oracle.com/cd/B28359_01/gateways.111/b31042/configodbc.htm

In result I have error:
$ tnsping postgresql
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = xxx)(PORT = 5432)) (CONNECT_DATA = (SID = postgresql)) (HS = OK))
TNS-12537: TNS:connection closed

When I try to connect by unixODBC, it connects:
$ isql -v postgresql
---------------------------------------
| Connected! |

| sql-statement |
| help [tablename] |
| quit |

---------------------------------------

Please help where I'm wrong? :(
