Preface
This publication describes job management facilities that can be influenced
by the system programmer.
Part I, the allocation section, discusses volume attributes, considerations in
allocating direct access storage devices, and the function of dynamic
allocation. Dynamic allocation can be invoked through DYNALLOC macro
instruction or through dynamic allocation interface routine (DAIR). This
publication discusses the DYNALLOC macro instruction and its associated
parameter structure, and reference information for the parameter structure.
Part II, the JES2 section, describes those aspects of JES2 processing that can
be affected during system generation, during system initialization, or by user
programming. The discussion is intended to tell the system programmer how
he can affect JES2 processing but not to tell him how to code the system
generation macro instructions and other initialization parameters.
Part III, the miscellaneous job management section, discusses restarting
support, assigning special program properties, limiting user region size,
changing the system log processing, updating MSTRJCL data set, and the
external writer.
JES3 and Mass Storage Systems information contained in this publication is
I for planning purposes only until the availability of the products.
