When you configure the OLE/DB Provider for DB2, if the user name and password are left blank in the Data Link Properties sheet, or if only the password field is blank, SNA Server 4.0 Service Pack (SP) 2 prompts you for the information with a dialog box; however, in this same scenario, SNA Server 4.0 SP3 fails with the following error message:
Test connection failed because of an error in initializing provider. Command syntax error. SQLSTATE: HY000, SQLCODE: -379
This is due to a change in the MDAC DataLink default behavior. With the new MDAC, the default for the DBPROP_INIT_PROMPT is DBPROMPT_NOPROMPT, and not DBPROMPT_COMPLETE.
In order to be prompted for the missing user ID and password, edit the UDL by adding another parameter, "Prompt=2," into the connection string.
To edit the UDL, start Windows Notepad, and open the problem *.udl file. At the end of the connection string, add the following parameter with no spaces between it and the last entry:
;Prompt=2Save the *.udl file, and then attempt the test connection again.
