ABSTRACT OF PROBLEM
___________________
Enhancements  to  TPF  MQSeries  Local  Queue Manager Support to
include Slow Queue Sweeper and Move Messages.


COMMENTS ON PROBLEM
___________________
Move Messages

With Turbo MQSeries support, when  a  processor  is  deactivated
from  a loosely coupled complex and messages are still in memory
queues on that deactivated  processor,  TPF  customers  have  no
mechanism  to  recover these messages to make them available for
MQSeries applications to process within the complex.

Slow Queue Sweeper

With Turbo  MQSeries  support,  the  original  Sweeper  releases
system  work  blocks  from local memory queues that had not been
serviced in a user-defined period of time. This  mechanism  does
not  address  the condition of a queue being serviced regularly,
but inadequately.  As a result, the queue has the  potential  to
use  a  large  amount of system resources unnecessarily, thereby
degrading performance.


SOLUTION
________
The following changes have been made to Turbo MQSeries support:

Move Messages

Messages residing in local memory queues can now be moved from a
queue  in  one deactivated processor to another processor in the
loosely  coupled  complex.  A  new  functional  message,   ZMQSC
MOVEMSGS,  is  provided  to allow customers to use this support.
This function is supported for normal local queues and does  not
include transmission queues.

Slow Queue Sweeper

Queues  will now be swept once the amount of messages put on the
queue exceeds the service rate. With the slow queue  sweeper,  a
queue  that  grows slowly in size will be moved to file, thereby
freeing up system memory resources.
