FUNCTIONS:
1) Periodically write a file of accounting
information about currently-running jobs. The
Monitor appends this file to the main accounting
file <ACCOUNTS>FACT.BIN at system startup time.
2) Compile accounting statistics on disk space
utilization.
COMMANDS
CHECKPOINT (EVERY) N (MINUTES)
APPEND (DISK STATISTICS TO) FILE-SPEC
LIST (DISK STATISTICS ON) FILE-SPEC
RENAME (FACT FILE TO) FACT.DD-MMM-YY-TIME
SET (CHECKPOINT INTERVAL TO) N (MINUTES)
ENTER (SINGLE CHECKPOINT)
HELP
EXIT (TO MONITOR)
OPERATION
Normally, CHKPNT is run under Job 0 to periodically
write the Checkpoint file. CHKPNT is usually run
manually to gather disk statistics once every week,
month, or once per billing period.
CHARACTERISTICS
The default interval between checkpoints of active
jobs is fifteen (15) minutes.
EXAMPLE
To set the default interval between checkpoints to a
new value, use the CHKPNT SET command and save the program
on SYS: as follows:
@R CHKPNT
TOPS20 CHECKPOINT VERSION 1
CHKPNT>SET (CHECKPOINT INTERVAL TO) 10 (MINUTES)
CHKPNT>EXIT (TO MONITOR)
@SAVE SYS:CHKPNT
CHKPNT.EXE.2 Saved
@
RESTRICTIONS
WHEEL or OPERATOR capability is required to write
checkpoint data and to compile disk statistics.
