Administrative and Operational Enhancements › System Definition Enhancements

System Definition Enhancements

The SYSGEN SYSTEM statement was enhanced to give you control over more system attributes. You can now perform the following actions:

• Specify default values for queue and message retention periods
• Override the line length for all printers in your system
• Control the number of message buffers used by the debugger

These changes facilitate tailoring a DC/UCF system to meet your operational needs.

SYSGEN SYSTEM Statement for Runtime Options

The SYSGEN SYSTEM statement was enhanced to give you control over more runtime options.

SYSGEN SYSTEM Parameters for Runtime Options

This section describes the new parameters for the system definition for the SYSTEM statement:

DEBug MESsage BUFfers is buffer-count

Specifies the number of message buffers used by the CA IDMS online debugger.

Increasing the number of message buffers enables the debugger to display more symbols and list more information. However, the larger the value you specify, the more storage is needed to execute the debugger.

Limits: 5 - 30

Default: 5 (buffers)

MESsage RETention is

Specifies the time period that the system retains messages generated by the SEND command. Messages whose retention period has expired are automatically deleted the next time you start your system.

message-retention-period

Specifies the number of days that messages are retained.

Limits: 0 - 255 (255 is synonymous with FOREVER; 0 is synonymous with 1)

Default: 7 (days)

FORever|OFF

Directs your system to not delete messages based on a retention period. FOREVER and OFF are synonyms that you can use interchangeably.

OVErriding REPort LINe LENgth is report-line-length

Specifies the line length to be used for all reports generated within a DC/UCF system.

Limits: 0 -255.

If this parameter is 0 (zero) or not specified, the line length used is based on the terminal’s device type. Because specifying a non-zero value impacts all DC/UCF reports, exercise caution if you set this parameter.

QUEue RETention is

Specifies the default time period that the system retains queues that are created dynamically. This value is used only if no retention period is specified when a queue is created. Queues whose retention period has expired are deleted automatically when the system is next started.

queue-retention-period

Specifies the number of days that queues are to be retained.

Limits: 0 - 255 (255 is synonymous with FOREVER; 0 is synonymous with 1)

FORever|OFF

Directs the system not to delete queues based on a retention period. FOREVER and OFF are synonyms that you can use interchangeably.
