Peter, The IBM JZOS Launcher, as you suspect, is used exclusively to run Java from a batch job step. In addition to creating and running a JVM, the JZOS batch launcher handles std stream redirection and character set transcoding. It also provides Java - MVS console integration. It is packaged as part of the IBM Java SDK along with the rest of the JZOS Batch Toolkit: http://www-03.ibm.com/systems/z/os/zos/tools/java/products/jzos/overview.html
COZBATCH is a "better" BPXBATCH - a program that runs a Unix command or shell from a batch job step. It is not specific to Java. It is designed to provide better integration between batch jobs and z/OS Unix System Services. Within the Co:Z Toolkit, COZBATCH is often used to script the operation of our z/OS sftp client (cozsftp) for secure file transfer, but it can be used for many other things as well. You *can* use COZBATCH to run a Java program, but you won't get the Java specific benefits that the JZOS Batch Launcher provides. Finally, (I know you mentioned just two, but there is another tool as well) Co:Z Launcher is used to launch a process on a remote system (e.g. a standalone Linux or Windows machine, an IFL running Linux for System Z, or a zBX running Linux, AIX or Windows) from a z/OS batch job. The launched process runs on the target system, but can "reach back" into z/OS to read/write datasets and z/OS Unix files. The Co:Z Launcher is used to implement what we refer to as z/OS Hybrid Batch Processing. This link provides an overview: http://dovetail.com/solutions.html Also at that link are a couple of Hybrid Batch case studies that might be worth looking at. The Co:Z Toolkit is free to use under our community license. --Steve Goetze Dovetailed Technologies www.dovetail.com On Wed, Jun 20, 2012 at 11:50 PM, Peter Bishop <[email protected]> wrote: > Hi List, > > I have read some of the fine manuals but have a basic question: > > what is the difference between the IBM JZOS Launcher and the Dovetail Co:Z > Launcher? > > I've downloaded the latter and am getting started with it.
