OCCI: Problem with CreateConnection() method

October 11Hits:0
Advertisement
I am using OCCI sdk for Oracle 10g database with VS2005. I am continuously getting an exception
"An unhandled exception of type 'System.Runtime.InteropServices.SEHException' occurred in OCCITest.exe
Additional information: External component has thrown an exception."
I get this exception at line:
user = "SYSTEM";
pass = "abc123";
db = "//127.0.0.1:1521/orcl";
     ->     con = env->createConnection(user, pass, db);
I have seen lots of posts with people asking this question... i tried almost all the alternatives specified in those posts. Even my Sqlplus works with this connection string. In sql plus, i can connect using these credentials, can create a table, insert data... etc. But I just can't connect from VC++...
For reference, I am pasting the entry in my tnsnames.ora file below:
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
I am using Vista machine. I have installed oracle 10g for vista. Can my OS be a problem? I will really appreciate the help...
Regards,
Jwalant

Answers

This may be obvious, but please verify that you have first created the environment before calling CreateConnection...
Environment *env = Environment::createEnvironment (Environment::DEFAULT);
Connection *con = env->createConnection (<user>, <password>, <connStr>);
