The builder modules:
- Make the autoinstall process possible (that is, build a terminal control
table terminal entry (TCTTE) dynamically).
- Allows new TCT entries to be added on a running CICS® system.
- Allow the TCT to be dynamically updated on a running CICS system.
- Allow TCT entries to be deleted on a running CICS system.
- Reduce emergency restart times for those systems that use the autoinstall
function. These systems have to take the time to restore and recover only
those terminals that were autoinstalled at the time of termination.
- Reduce warm start times for those systems that use auto-install. No auto-installed
terminals (except LU6.2 parallel systems are recovered at warm start).
- Reduce shutdown times for those systems using auto-install. Auto-install
catalog entries are deleted but the entry in storage is not destroyed during
shutdown.
In this topic, the term TCTTE is used in a general way to refer to the
terminal control table entries for connections (TCT system entries, TCTSEs),
mode groups (TCT modegroup entries, TCTMEs), sessions (session TCT terminal
entries, TCTTEs), skeletons (TCTSKs), and models.
To build or delete a control block for a particular device, a set of builders
is called. The set of builders is specified by a tree structure of patterns,
each pattern specifying one builder.
The builder modules (DFHBS*) are link-edited together into the DFHZCQ load
module.
On microfiche, the individual DFHBS* modules are listed separately.
