PCS report

This report provides an overview of the activities of the Performance Control Subsystem.

Report output

The REPORT PCS statement is used to request the output of the PCS report.The report can only be output if PCS was active during the last monitoring cycle.

Monitoring information

This report contains the totals (SUM column) for all categories (except for the SQPLN value) in the first line below the table header. The data for the individual categories (up to 16) is output in the following lines.

CATEGORY NAME	Name of a category
SRACT (SU/S)	Service unit per second of this category, specified as TOTAL, IO and CPU
TOTAL	Total number of service units per second of this category (sum of IO, CPU and memory service rates)
IO	IO service units per second of this category
CPU	CPU service units per second of this category
SQPLN (%)	System performance percentage planned for this category This variable is irrelevant for the SUM category and is therefore replaced by blanks.
SQACT(%)	Current percentage of system performance for this category
RDACT	Current delay of all jobs in this category If no dilation was sensed, ** is output (see “dilation factor” in the glossary). A system-global value is given in the SUM line.
DUR-RO (1/S)	Number of DURATION time slice runouts for tasks in this category The given service rate has been used up, the task is placed in the defined continuation category.
DUR-RO-P (1/S)	Number of DURATION time slice runouts with preemption for tasks or jobs in this category Meaning as above; since the defined continuation category is not permitted because of overloading, the task is entered in task queue 6.
