Guidelines
MEMORY PAGES
displays the number of physical pages (two kilobytes) installed on this processor.
PCBS SGEN
displays the process control blocks (PCBs) generated in the measured system.
LCBS SGEN
displays the link control blocks (LCBs) generated in the measured system.
TLES SGEN
displays the number of timer list elements (TLEs) generated in the measured
system.
BPTS SGEN
displays the number of breakpoints generated in the measured system.
SPOOL WDS
displays the number of spooler words generated in the measured system.
MPOOL KWDS
displays the number of map pool words (in thousands) generated in the measured
system.
Guidelines
These critical items are global variables:
1. PCBs - The number of process control blocks (PCB) restricts the number of
processes that can be run concurrently on a processor. The maximum number of
processes that can execute on a system is limited by the total number of PCBs
across all processors.
2. LCBs - The number of link control blocks (LCB) determines the maximum number
of interprocess messages outstanding between pairs of processes. Typically HP
system processes and subsystem processes reserve two LCBs to guarantee their
operation. These reserved LCBs are removed from the general pool and are not
available for user processes to use. Failure to allocate LCBs is typically sufficient
reason for a process to terminate abnormally.
3. TLEs - The number of timer list elements (TLE) determines how many concurrent
timers can be in effect on a processor.
4. BPTs - The number of break points (BPT) determines the maximum number of
concurrent breakpoints that can be in effect on a processor at a given time. This
limit is typically not a problem on production systems where few if any breakpoints
