AIQMAX

The AIQMAX parameter specifies the maximum number of z/OS® Communications Server terminals and APPC connections that can be queued concurrently for autoinstall, the limit is the sum of installs and deletes.

AIQMAX={100|number}: The value for this parameter must be a number in the range 0 through 999. The default is 100. A zero value disables the autoinstall function.
Specify a number that is large enough to allow for installs and deletes of both APPC connections and terminals.

Note: This value does not limit the total number of terminals that can be autoinstalled. If you have a large number of terminals autoinstalled, shutdown can fail due to the MXT system initialization parameter being reached or CICS® becoming short on storage. For information about preventing this possible cause of shutdown failure, see MVS™ and DASD: improving performance.
