Descrição:

The SET SYSTEM command allows you to change the values of some of the options that control the execution of your CICS system.

Opções:

AKP(data-value)
• Specifies, as a 32-bit binary value, the trigger value for the activity keypoint, which is the number of log operations that occur between the taking of keypoints.
• The number must be either zero, which turns off keypointing, or in the range 200 through 65535.

DFLTREMSYS(data-value)
• Specifies the four-character name of a new default remote system.
• TXSeries for Multiplatforms assumes the local system ID.
• TXSeries for Multiplatforms checks this value only for validity; otherwise, it ignores this value.

DSALIMIT(data-value)
• Specifies, as a 32-bit binary value, the maximum amount of storage, in bytes, within which CICS can allocate storage for the four individual dynamic storage areas (DSAs) that reside below the 16 MB boundary.
• The range for DSALIMIT is 2 MB through 16 MB.
• TXSeries for Multiplatforms checks this value for only validity; otherwise, it ignores this value.

DTRPROGRAM(data-value)
• Specifies the eight-character name of the program that is to control the dynamic routing of transactions.
• TXSeries for Multiplatforms ignores this value.

DUMPING(cvda)
• Specifies a CVDA value that indicates whether the taking of CICS system dumps is to be suppressed.
• The CVDA values are:
  • NOSYSDUMP
    • System dumps are to be suppressed.
  • SYSDUMP
    • System dumps are not to be suppressed.

EDSALIMIT(data-value)
• Specifies, as a 32-bit binary value, the maximum amount of storage, in bytes, within which CICS can allocate storage for the four individual dynamic storage areas that reside above the 16 MB boundary.
• The range for EDSALIMIT is 10 MB through 2 GB.
• TXSeries for Multiplatforms checks this value only for validity; otherwise, it ignores this value.

GMMLENGTH(data-value)
• Specifies, as a 16-bit binary value, the length of the "good morning" message text.
• The range for this value is 1 through 246.
• TXSeries for Multiplatforms checks this value only for validity; otherwise, it ignores this value.

GMMTEXT(data-value)
• Specifies the "good morning" message text, which can be up to 246 characters long.
• TXSeries for Multiplatforms ignores this value.

MAXSERVER(data-area)
• Dynamically changes the maximum number of application servers.

MAXTASKS(data-value)
• Specifies, as a 32-bit binary value, the maximum number of tasks that can be eligible for dispatch at any one time in this CICS system.
• Active and suspended tasks both count toward this limit, but tasks that have not reached the point of initial dispatch do not.
  
• The value can be in the range 1 through 999.
• TXSeries for Multiplatforms checks this value only for validity; otherwise, it ignores this value.

M0INSERVER(data-area)
• Dynamically changes the minimum number of application servers.

MROBATCH(data-value)
• Specifies, as a 32-bit binary value, the number of events that must occur, from a list of multiregion operations (MRO) and Direct Access Storage Device Input/Output (DASD I/O) events on which CICS is waiting, before CICS is posted explicitly to process them.
• The value must be in the range 1 through 255.
• TXSeries for Multiplatforms checks this value only for validity; otherwise, it ignores this value.

NEWMAXTASKS(data-area)
• Returns the new value of MAXTASKS, in 32-bit binary form.

PROGAUTOCTLG(cvda)
• Specifies whether and when autoinstalled program definitions are to be cataloged.
• The CVDA values are:
  • CTLGALL
    • Definitions are to be cataloged when installed and when modified.
  • CTLGMODIFY
    • Definitions are to be cataloged only when modified.
  • CTLGNONE
    • Definitions are not to be cataloged.
• TXSeries for Multiplatforms checks this value only for validity; otherwise, it ignores this value.

PROGAUTOEXIT(data-value)
• Specifies the eight-character name of the user-provided program that is to be called by the CICS program autoinstall code to provide a model definition.
• This action installs the program autoinstall user exit (user exit 13).

PROGAUTOINST(cvda)
• Specifies whether autoinstall for programs is to be active or inactive.
• When a task requests a program that is not defined, CICS attempts to create a definition for it automatically.
• The CVDA values are:
  • AUTOACTIVE
    • Autoinstall for programs is to be active.
  • AUTOINACTIVE
    • Autoinstall for programs is to be inactive.

PRTYAGING(data-value)
• Specifies, as a 32-bit binary value, the rate at which CICS is to increase the priority of a task that is waiting for dispatch.
• The value must be in the range 0 through 65535.
• TXSeries for Multiplatforms checks this value only for validity; otherwise, it ignores this value.

RUNAWAY(data-value)
• Specifies, as a 32-bit binary value, the default for runaway task time.
• The value must be either zero or in the range 500 through 2700000.
• TXSeries for Multiplatforms checks this value only for validity; otherwise, it ignores this value.

SCANDELAY(data-value)
• Specifies, as a 32-bit binary value, the maximum number of milliseconds between the time at which a user task makes a terminal I/O request and the time at which CICS dispatches the terminal control task to process it.
• The value must be in the range 0 through 5000.
• TXSeries for Multiplatforms checks this value only for validity; otherwise, it ignores this value.

TIME(data-value)
• Specifies, as a 32-bit binary value, the maximum interval in milliseconds for which CICS gives control to the operating system if no tasks are ready for dispatch.
• The TIME value must be in the range 100 through 3600000.
• TXSeries for Multiplatforms checks this value only for validity; otherwise, it ignores this value.

XPRECVTIMEOUT(data-value)
• Specifies the interval, in seconds, that CICS waits before timing out receive operations between CICS application servers and list processes.
• This value must be in the range of 0 (zero) through the value that is specified in the INT_MAX constant.
• The value of INT_MAX is system-dependent. For 32-bit systems, the value is 2147483647 seconds.
• The default value that is returned is the value of the Region Definitions (RD) XPRecvTimeout attribute.
• Setting this value to greater than 0 (zero) seconds can cause transactions that run for long periods of time (such as CEMT) to time out before completing.
