The AIRDELAY parameter
specifies the delay period that elapses after an emergency restart
before autoinstalled terminal and APPC connection entries that are
not in session are deleted.
- AIRDELAY={700|hhmmss}
- The AIRDELAY parameter also applies when
you issue a z/OS Communications ServerCEMT SET VTAM OPEN command
after a z/OS Communications Server abend and PSTYPE=MNPS is coded.
This causes autoinstalled resources to be deleted, if the session
was not restored and has not been used since the ACB was opened.
The AIRDELAY parameter
does not apply to the following types of autoinstalled APPC connection,
which are always written to the CICS global catalog and recovered
during a warm or emergency start:
- Sync level 2-capable connections (for example, CICS-to-CICS connections)
- Sync level 1-capable, limited resource connections installed on
a CICS that is a member of a generic resource group
- hhmmss
- A 1-to 6-digit number. If you leave out the leading zeros, they
are supplied. The default is 700, meaning a delay of 7 minutes. A
value of 0 means that autoinstalled definitions are not written to
the global catalog and therefore are not restored at an emergency
restart.
For guidance about the performance implications of setting
different AIRDELAY values, see MVS and DASD: improving performance.
