:>Just an inquiry, to see if others have had issues with this products 
use/abuse of XCF. BMC product is sending large bursts of XCF traffic between 
systems, and the messages are the maximum size (62464). Over the past few 
months, it has sent bursts like these (over 8K large messages in 1 minute 
interval), and filled up XCF buffers on the sending system (transport class we 
use for large message traffic). We are going to isolate the product's XCF group 
(DCPLEX$) into its own transport class, so it cant block other users of the our 
general-purpose large message transport class.

:>Product does reporting, and sends its results back to a focal point (sessions 
used by DBAs etc) for analysis. Spoke with the vendor, they stated the options 
are - a) turn off the XCF mechanism in the product or b) enable it for XCF 
communication, but there is no control over what it may send (unlimited). These 
seem like poor choice of options for tuning it. If XCF is disabled, DBAs would 
not be able to assemble reports for DB2 using data sharing for multi-system 
operation.

I would ask if the XCF bursts are connected with the end-user/DBA requests for
data. Perhaps a screen that is refreshed frequently?

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
