connect Netezza database to CASLIB using odbc data connector

[marathon2]

I used the following codes to create a caslib that connects to Netezza databases. However, I can't make the connections successfully.

proc cas;
caslib odbctables desc="odbc_conn" sessref=mySession datasource= (srctype="odbc", authenticationDomain="NZAuth", odbc_dsn="INSERT_DSN_NAME", schema="INSERT_SCHEMA_NAME", catalog="*");

quit;

ERROR: The connection to the data source driver failed.

ERROR: Invalid value for connection string attribute CATALOG: ODBCCASLIB

ERROR: Function failed.

ERROR: The action stopped due to errors.

I set up an odbc connection using "ODBC Data Sources" on Windows, where the dsn name equals "INSERT_DSN_NAME"; I also tested the connection, to make sure the connection worked.
