Minimum required statements
To begin using JES2, it is not required to configure any of the more sophisticated processing environments, such as a multi-access spool complex, nodes or remote workstations. You can begin by simply building a base upon which your system can grow. To assist with JES2 initialization, a sample initialization data set is shipped with the product. This sample data set, shipped in SYS1.PARMLIB, requires only the addition of installation-defined devices and installation-specific values. It contains all of the JES2 initialization statements and the defaults for all parameters.
A customized initialization data set is provided by IBM® for each Custom Built Product Delivery Offering (CBPDO). 1
1 CBPDO is an IBM offering that builds, customizes, and delivers
a full MVS™ operating system;
only the installation is required. CBPDO is useful for all new MVS installations to ease the migration
effort from the previous operating system, and is particularly useful
for brand new MVS installations.
