Hi,

Are you able to connect to Oracle normally through SQL plus?

Did you create a system DSN for the database to be used in the ODBC?

hi,
yaa i was able to connect to oracle normally, but there too i just gave user name and pass word, didn't give the service name ie CONNECTION STRING NAME.I creates DSN but there is no option to check the connection there itself, there is no option to test the connection while creating DSN.

plz gurus help me out.

itself, there is no option to test the connection while creating DSN.

I'm very sure that when you create a DSN for an Oracle DB in Windows, you can test the connection.

I'd say you double check.

hi GURUS;
when creating odbc connection i have given the following parameters.
i have choosen SYSTEM DSN and selected MICROSOFT ODBC DRIVERS FOR ORACLE.

There are options to specify the datasource name, server name, user name and additional options to increase the performance but no options to test the connection.

We are using Oracle 9i, still couldnot resolve the problem.
plz help me out.

There isn't a directory (folder) called DSHOME; that's a short cut (and may, if you set it up, be an environment variable). Location of the directory in question is "whereever you installed the server directory", by default C:\Ascential\DataStage\Engine.

However, on Windows there is no .odbc.ini file - this is for UNIX servers only. In Windows everything is done in the Registry.

Try creating a System DSN using the Data Direct ODBC drivers that ship with DataStage, rather than the Microsoft ODBC drivers.

And make sure that the executing user has the Oracle environment variables, such as ORACLE_HOME, correctly set.

hi,
tried hard but couldn't find the $DSHOME DIRECTORY so that i can configure the orahome path.
went to c\ascential\engine.
could find text folders like UVCONFIG,UV.LOGINS,VOC,UV.ACCOUNT,.UVCONFIG.
could find directories like UVTEMP,INCLUDE,DS_LICENSE.
getting error - DSR.METADATA[GET.DSNINFO]
BCI ERROR:SQL STATE=NA600[DATASTAGE][SQL CLINET][ODBC][MICROSOFT]ODBC DRIVER FOR ORACLE][ORACLE]ORA-12541.
TNS:NO LISTENER.

You will have to set the ORAHOME path in the dsenv file.

[chulett]

There is no dsenv file on a Windows server. That's a UNIX only concept, Windows controls all that via the registry.

You can set environment variables on Windows through Control Panel. Choose the System applet, there's a command button for environment variables. You may need to re-boot (go Microsoft!) for them to take effect.
