Elements of the POOL Display



The maximum size of the SYSPOOL system storage pool for TNS/R (HP Tandem

NonStop Series/ RISC) processors and itanium processor can exceed the size

configured during system generation. Under the heading MAX.SIZE, the current

value reported for this pool can appear quite large.



The PTLE table has no entries when the processor first comes up after a system

load or reload. Entries are added dynamically on a demand basis.



TLE allocation failures are rare but can occur under certain conditions. Up to 100

TLEs are required for system processes. When TLEs are allocated, system

processes are favored over nonsystem processes. If the number of free TLEs

drops to 100 or less, nonsystem processes are not allowed to allocate TLEs. TLE

allocation failures are indicated in the # OF FAILURES column for TLEs.

To help identify the source of TLE allocation failures, subtract the MAXIMUM

USED total from the # CONFIGURED total:



If the difference is between 1 and 100, nonsystem processes might have had

TLE allocation failures.



If the difference is zero, even system processes might have had TLE allocation

failures.



If the difference is more than 100, but close to that number, you might want to

take preventive action to avoid TLE allocation failures.

To prevent TLE allocation failures, try to reduce the use of TLEs in the processor.

For example, look for processes that call SIGNALTIMEOUT for many different

timers in use simultaneously. On systems running G-series and H-series RVUs, the

number of TLEs is automatically set to the maximum possible and cannot be

changed.
