DESCRIPTION OF PROBLEMS FIXED AND ENHANCEMENTS
----------------------------------------------
 (1)
   THE TUNER REQUIRES A TABLE OF VALID COMBINATIONS OF PROCESSOR
   POWER AND INTERACTIVE PERFORMANCE IN A PARTITION.  THIS TABLE
   IS BUILT INITIALLY WHEN THE TUNER IS FIRST STARTED.  AT EACH
   SUBSEQUENT TUNER START (AND OCCASIONALLY DURING OPERATION)
   SEVERAL POINTS IN THE TABLE ARE CHECKED FOR CURRENT ACCURACY.
   THE ALLOWANCE OF ZERO INTERACTIVE PERCENTAGE IN OS/400 V5R2
   WAS NOT COMPLETELY HANDLED AND RESULTED IN THE TABLE BEING
   REBUILT EVERY TIME THE TUNER WAS STARTED FOR SOME MACHINE
   CONFIGURATIONS.  THIS CAN BE A LENGTHY PROCESS BEFORE THE
   TUNER CAN MAKE RESOURCE ADJUSTMENTS.

 (2)
   IF THE "CONNECTION ENTRY" WAS NEVER ENTERED IN A SECONDARY
   PARTITION BUT THE PARTITION AGENT WAS STARTED NONETHELESS,
   THE AGENT RETRIED THE CONNECTION TO THE PRIMARY PARTITION
   REPEATEDLY.  THIS SITUATION WILL NOW RESULT IN AN AGENT
   ABORT WITH A DESCRIPTIVE *ESCAPE MESSAGE.  ALSO, RETRIES
   OF THE CONNECTION AFTER A DISCONNECT NOW OCCUR AFTER A SHORT
   DELAY TO ALLOW THE COMMUNICATIONS CHANNEL TO "CLEAR" AND
   TO AVOID EXCESSIVE JOB LOG MESSAGES.

 (ENHANCEMENT)
   THE "WRKAPRM" DISPLAY HAS BEEN ENHANCED SLIGHTLY TO BETTER
   USE THE LIMITED SCREEN WIDTH AND TO CORRECTLY DISPLAY THE
   PARTITION NAME FOR A LINUX PARTITION.  THE JAVA-BASED
   OPNAV PLUGIN IS UNCHANGED AS IT ALREADY SUPPORTED THOSE
   CHARACTERISTICS.


CORRECTION FOR PROBLEMS
-----------------------
   THIS FIX CHANGES THE ALGORITHM USED TO GENERATE THE VALIDITY
   TABLE AND CORRECTLY DETECT WHEN IT MUST BE CHANGED.  ALSO,
   AN OMITTED CONNECTION ENTRY IS DIAGNOSED BY THE PARTITION
   AGENT.


CIRCUMVENTION FOR PROBLEMS
--------------------------
   (1) NONE.
   (2) ENTER A CONNECTION ENTRY IN A SECONDARY PARTITION BEFORE
         STARTING THE PARTITION AGENT.


ACTIVATION INSTRUCTIONS
-----------------------

   APPLY THIS PTF IN THE PRIMARY PARTITION ONLY - IT WILL BE
   PROPAGATED TO EACH SECONDARY WHEN THAT PARTITION NEXT
   CONNECTS TO THE PRIMARY.  IT IS ALLOWED TO APPLY THIS
   PTF TO SOME/ALL SECONDARIES TO AVOID THE NEED FOR SENDING
   IT OVER THE SOCKET CONNECTIONS, BUT THE SECONDARY MUST NOT
   COMMUNICATE WITH THE PRIMARY AFTER THE PTF IS APPLIED UNTIL
   THE PRIMARY ALSO HAS THE PTF APPLIED (OTHERWISE THE PRIMARY
   WILL UNINSTALL THE PTF IN THE SECONDARY).

   APRM MUST NOT BE IN USE WHILE THIS PTF IS APPLIED.  IT MAY
   BE STOPPED BY CMD(ENDAPRM).  IF THE INSTALL IS DONE IN THE
   PRIMARY PARTITION, APRM ACTIVITY NEED ONLY BE STOPPED IN
   THE PRIMARY PARTITION (THE SECONDARY PARTITIONS WILL WAIT
   UNTIL APRM IS RESTARTED IN THE PRIMARY PARTITION AUTOMATICALLY).
   IT IS ALSO NECESSARY TO DISCONTINUE USE OF APRM THROUGH
   COMMANDS "WRKAPRM" (ETC.) AND THE JAVA-BASED OPNAV PLUGIN
   BECAUSE THEY ALL USE OBJECTS IN THE QBARSA LIBRARY WHILE
   THEY ARE ACTIVE.

   AFTER THE PTF HAS BEEN INSTALLED INTO THE PRIMARY PARTITION,
   APRM MAY BE RESTARTED WITH CMD(STRAPRM).
