APAR Error Description / Circumvention

-------------------------------------------------
WRKSYSSTS and WRKDSKSTS commands hang.

CORRECTION FOR APAR 'MA47445' :
-------------------------------
A trace table was deleted while the size of the table was being
changed. This caused the LIC logging code to take a system
exception which left the Trace control block gate locked.
The locked gate prevented WRKSYSSTS and WRKDSKSTS and other
Trace commands from working.
The system needed to be IPLed to remove the gate lock.

The LIC logging code was changed to try and close a window which
allowed the trace table to be deleted while being updated. Also,
an exception handler was installed during the update such that
if an exception occurred the gate lock would be released.

The PTF can be applied without an IPL, but if the system is
already in the hang state it will not release the gate lock, an
IPL will still be required.

CIRCUMVENTION FOR APAR 'MA47445' :
