Unlocks           (VSAM)

DESCRIPTION
"Unlocks" shows the total number of times a "Dataset" was unlocked from a 
previous lock.


VALUES
The number of "Unlocks" is an integer that Sun MTP initializes to zero at system
initiation. "Unlocks" increases as data activity transpires.

INTERPRETATION
If "Unlocks" does not match "Locks", then the "Dataset" may either be locked for
normal processing or possibly involved in a program logic error. An error or 
deadlock is evident when the two datapoints differ in value and do not change 
for an extended period of time.


CONCLUSIONS
When system performance seems to be degrading, examine the "Unlocks" and "Locks"
datapoints for a system's datasets. If these values remain constant when they
should both be increasing with file activity, the system is probably in 
deadlock. Note that these values should become identical and not change when
the system is idle. If the values do not change and they are different, there 
may be an internal Sun MTP problem.
