:>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.
