RegardsBaraa From: bem85@hotmail.com To: users-list@monetdb.org Subject: Accessing MonetDB form Oracle DB Date: Fri, 25 Oct 2013 11:13:37 +0000 Dear MonetDB users, I have a question about accessing MonetDB via Oracle using ODBC. I have oracle on machine1 (ubuntu 64bit) and MonetDB on machine2(ubuntu 64bit)I installed Monetdb odbc driver using apt-get install libmonetdb-client-odbc I have done all the needed configurations for the listner, tnsnames, sqlnet, initservice.ora and I used UnixODBC. After creating the database link, I get this error when I try to connect MonetDB: ORA-28500: connection from ORACLE to a non-Oracle system returned this message:[unixODBC][MonetDB][ODBC Driver 11.11.11]Client unable to establish connection{08001}ORA-02063: preceding 2 lines from MONETDB I don't know if the use of (64bit) needs some special configurations?? or its du to something else. So I need your help to figure out what is the problem....
