File techniques in CICS programs
Defining CICS® programs
is much the same as defining programs for other environments. There
are some file technique considerations you should note that are specific
to CICS.
- Using temporary storage
- Using transient data queues
You can use transient data queues for many of the same
purposes as an auxiliary temporary storage queue.
- Using spool files in z/OS CICS
EGL programs generated for CICS for z/OS can access JES SPOOL files
if the serial or print file is associated with the spool file
type at generation.
- Using spool files in VSE CICS
EGL programs generated for VSE batch or CICS for VSE can create and write to a VSE/POWER
queue member by setting the fileType property
to spool in the resource association for
the serial or print file at generation.
- Using VSAM files
An EGL program generated for CICS can
access VSAM files if the serial, indexed or relative file is associated
with the vsam file type at generation.
- Using recordName.resourceAssociation
You can dynamically change the physical file associated
with a record at run time.
