This noble operating system has evolved from OS/360 through MVT, OS/VS2, and MVS to OS/390.  During this time, the hardware has transformed from a 'big iron' dinosaur to an Open Server (!) which can run NT alongside UNIX applications alongside more standard 'mainframe' applications.

These durable systems will be with us for many years yet.  Here we introduce the Oakwood courses for mainframe system software:

• OS/390 Overview


• Writing OS/390 JCL


• Operating a JES2 system


• Using TSO and ISPF


• DB2 for Operators


• DB2 and SQL for Programmers


• Using VSAM


• CICS for Operators


• CICS for Programmers


• Writing REXX execs


• Developing ISPF Panels and Dialogs
