APAR Error Description / Circumvention

-------------------------------------------------
A Collection Services cycle can be delayed if the time required
to collect *JAVA category data is long. This has been observed
when the number of JVMs on a system exceeds 500 and JVMs are
slow to respond to data requests.

CORRECTION FOR APAR 'SE54513' :
-------------------------------
During a cycle, the collector waits for all category data to be
collected before ending the current collection and starting a
new one. When a long *JAVA collection interval occurs, a cycle
can be delayed.

This change allows the collector to notify the *JAVA collection
probe that a cycle has started.

CIRCUMVENTION FOR APAR 'SE54513' :
----------------------------------
None.


Activation Instructions


None.




Special Instructions

After applying or removing this PTF the Collection Services collector
job (QYPSPFRCOL) must be ended and restarted for the change to take
effect.

1. To end Collection Services enter the following on the command
line:
ENDPFRCOL FRCCOLEND(*YES)

2. To start Collection Services enter the following on the command
line:
STRPFRCOL

Before restarting Collection Services, you should consider other
functions that may be using data provided by Collection Services. Such
functions may be impacted when Collection Services is ended. Error
messages may be produced and the affected functions may need to be
restarted.

Examples of functions that are dependent on Collection Services include
Management Central monitors and applications that use the performance
collector APIs QPMWKCOL and QPMLPFRD. If applications are using the
performance collector APIs, you will find server jobs QPMASERV and
QPMACLCT active on your system.

********************************************************************
THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED
PTF HAS ALREADY BEEN APPLIED AND ITS SPECIAL INSTRUCTION FOLLOWED,
IT IS NOT NECESSARY TO FOLLOW THAT SPECIAL INSTRUCTION AGAIN.
********************************************************************

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI39923 :
=================================================

If the QPMACLCT job was active when this PTF was applied that job must
be ended and restarted for this fix to take effect. The QPMACLCT job
can be ended via the ENDJOB command with OPTION(*IMMED).  This action
may cause a failure in the client application which depends on the
QPMACLCT server. Restarting the client function will cause the QPMACLCT
job to be restarted.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
