As you can see, there are many product choices. I'd just chime in here and recommend that, whatever option you choose, make sure you implement so that the z/OS scheduling is self-contained -- assuming z/OS is the most highly available operating system you've got running, which is generally a safe assumption.
For example, you do NOT want your monthly billing to fail to start because a remote server (or network connection to it) did not initiate the job(s). Make the mainframe the "mother hen," basically. There's also the not-so-minor issue of the perils of scheduled FTP (or similar) as an application integration strategy, but I've editorialized about that in the recent past. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
