When the builders are called

Builders are called during the following operations.
Cold start
  • Read information from the CSD and call builders to build RDO-defined terminals.
  • Load in DFHTCT for non-z/OS® Communications Server terminals. Builders are not called.
Warm start
Note: A warm start is identical to an emergency restart from the builders perspective. The only difference is that Recovery Manager has no forward-recovery records to pass to DFHAPRDR.
  • Read information from the global catalog and call builders to restore RDO-defined terminals.
  • Load in DFHTCT for non-z/OS Communications Server terminals. Builders are not called.
Emergency restart
  • Read information from the global catalog and call builders to restore RDO-defined terminals.
    Note: Auto-installed terminals will not have a catalog entry if AIRDELAY=0
  • Recovery Manager calls DFHAPRDR which calls the builders to restore in-flight terminals installs from the system log.
  • Load in DFHTCT for non-z/OS Communications Server resources. Builders are not called.
After emergency restart

Delete autoinstalled terminals after the time period has expired as specified in the AIRDELAY parameter (if the user has not logged back on before then).

APPC autoinstall
  • Inquire on the model supplied by the autoinstall user program
  • Install an APPC connection created from this inquiry.
Autoinstall logon and logoff
  • Logon: Install terminal entry using model entry in the AMT.
  • Logoff: Delete terminal entry.
CEDA INSTALL

Install z/OS Communications Server terminal resources. (There is no builder process for CEDA DEFINE or ALTER.)

EXEC CICS CREATE

Install z/OS Communications Server terminal resources.

EXEC CICS DISCARD

Delete z/OS Communications Server terminal resources.

Transaction routing

If a TCTTE is defined as shippable, its definition is shipped to the remote system and installed there. The definition is obtained by an INQUIRE call to the builders in the terminal owning region and built with an INSTALL call in the Application Owning Region.

Non-immediate shutdown

Delete autoinstalled terminals from the catalog (if they had entries, and are not LU6.2 parallel connections). On a warm start, therefore, autoinstalled terminals are not recovered.
