The SHOW SYSRCT command displays summary or detail information about NCL performance groups. You can use the command to obtain either summary information about all four NCL performance groups or detailed statistics about a specific NCL performance group.
This command has the following format:
SHOW SYSRCT[ =SUMMARY | =n ]
(Default) Displays a single line for each performance group.
Displays detailed information about the nominated performance group with all priority levels.
The Resource Control Table contains controls for dynamically altering the performance of currently active NCL procedures based on their consumption of processing units and statistics recording their effects.
Each priority in a performance group has short term and long-term controls. Short-term controls apply to processing units consumed since the last voluntary loss of control, for example, an &PANEL statement. Long-term controls apply to processing units consumed since the procedure was initiated.
The four performance groups are BACKGROUND, OCS, FULLSCREEN, and SYSTEM, numbered 1 through 4 respectively.
Each performance group has an initial priority which can be displayed using the SHOW SYSPGT command. In the detailed display of the resource controls for a particular group (that is, SHOW SYSRCT=n), the initial priority is indicated by <=I=.

Displays the performance group number.
Displays the number of currently active procedures.
The statistics recording start time.
Displays the total number of procedures that have run in this performance group.
Displays the total number of forced waits that have occurred for all procedures that have run in this performance group.
The total number of times that a forced wait has been issued for the maximum or minimum duration.
Displays the total number of priority changes that have occurred for all procedures that have run in this performance group.
The detail information returned includes the previous statistics for long-term and short-term performance control measures, and the following performance control settings for priorities and forcing procedures to wait:
Displays the number of processing units that can be consumed by a procedure before a forced wait occurs.
Displays the number of processing units that can be consumed by a procedure before a priority change occurs.
Displays the length of time in hundredths of a second that a procedure is delayed for, after consuming the DELAY number of processing units for the first time.
Displays the length of time in hundredths of a second that the initial DELAY is adjusted by for subsequent times that the delay number of processing units is consumed.
Displays the maximum or minimum length of time a procedure is forced to wait.
Displays the new priority that is assigned to a procedure when it has consumed the CPRTY number of processing units.
