CEMT SET SYSTEM
CEMT SET SYSTEM
Function: Change the system attributes.
Syntax: Press the Clear key to clear the screen. There are two ways of commencing this transaction:
Type CEMT SET . The SYSTEM keyword does not have to be typed. If you type just CEMT SET , SYSTEM is assumed as the
default. You get a display that lists the current status, similar to that obtained by CEMT INQUIRE SYSTEM. You can then
tab to the highlighted or blank fields and overtype them with the required values.
Type CEMT SET followed by one or more attribute settings that you wish to change. For example, cemt s ag(value)
ma(value) resets the values for priority aging and the maximum number of tasks allowed at any one time in the CICS
system.
Typing ? at the beginning of either the first or second line gives a syntax prompt. Resetting the values takes effect immediately.

Options
AGing( value)
specifies the time factor for CICS to use in the priority
aging algorithm for incrementing the priority of a task.
The value is expressed as “milliseconds per unit of
priority”, and must be in the range 00000–65535. The
priority aging factor is defined initially by the PRTYAGE
system initialization parameter, in which the value
represents the number of milliseconds that must elapse
before the priority of a waiting task can be adjusted
upward by 1. See the
CICS System Definition Guide for
information about the PRTYAGE parameter.
AKp( value)
specifies the activity keypoint trigger value, which is the
number of write requests to the CICS system log stream
output buffer between the taking of keypoints. It must
have a value in the range 00200–65535. You cannot
change this value if AKPFREQ=0 was specified at
system initialization.
AUTOActive
Autoinstall for programs is active. On first use, if a
program, mapset, or partitionset is not defined, the
definition is created dynamically.
AUTOInactive
Autoinstall is not active. If a program is not defined, a
PGMIDERR or transaction abend occurs when it is
referenced.
CTLGAll
All autoinstalled program definitions are to be cataloged
and restored on a warm or emergency restart.
CTLGModify
Autoinstalled program definitions are to be cataloged
only if they are modified (for example, by a CEMT SET
PROGRAM command), so that the modified definitions
are restored on a warm or emergency restart.
CTLGNone
No autoinstalled program definitions are to be cataloged.
They are autoinstalled again after a warm or emergency
restart.
