You should be able to dig up much more information on the Toolbox at http://www.as400.ibm.com/toolbox/. Basically, you have to set a couple connection properties that tell it all about the package to use. Regards, Richard D.

The main reason is that ODBC uses package support (aka extended dynamic by default and the Java toolbox driver requires extra configuration to make use of that function. When I was testing ODBC I would normally see a 50% to 2X improvement in throughput with package support. Regards, Richard D.
