SYSPGT Command—Set Initial Priority for NCL Performance Group

The SYSPGT command is used to set the initial priority for an NCL performance group. You use the command as part of performance control. The command sets the priority that is assigned initially to procedures running in a performance group.

This command has the following format:

SYSPGT GROUP=n
       IPRTY=p

GROUP=n

Specifies the number of the performance group that is to have its initial priority set.

Limits: 1 through 4

IPRTY=p

Specifies the initial priority for the specified performance group. Zero is the lowest priority.

Limits: 0 through 3

You can use the SHOW SYSPGT command to determine the default initial priority for all performance groups.

The four performance groups are BACKGROUND, OCS, FULLSCREEN and SYSTEM, numbered 1 to 4, respectively.

A procedure can have its priority altered during execution depending on control values set in the Resource Control Table.

SYSPGT G=1 IP=1

SYSPGT GR=2 I=2
