You must setup the ODBC or OLEDB correctly in Windows first (Control panel). Test connection there first. Then select the Connection in VisualCron.
Okay I'm on the client machine and I have all the necessary drivers installed and even tested the connections through them via Control Panel -> Administrative Tools. I created a User DSN, System DSN, File DSN, and I have many drivers including the Oracle ones:
Driver: Microsoft ODBC for Oracle version 2.576.3959.00
Filename: MSORCL32.DLL
Date: 2/17/2007
Driver: Oracle in OraClient10g-home1 version 10.02.00.01
Filename: SQORA32.DLL
Date: 8/29/2005
I'm able to create a SQL Connection and test but when I use one of the many examples I created (i.e. using Connection Guide, using existing Data Source) I get this error:
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
