Problem summary
**************************************************************** USERS AFFECTED: Users querying channel status using runmqsc or PCF to check the BYTSSENT and BYTSRCVD attributes Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: MQ uses a 4 byte unsigned integer to store the BYTSSENT and BYTSRCVD attributes and the maximum value that can be stored is 4294967295(0xffffffff). A defect in the MQ code in handling the overflow in the BYTSSENT and BYTSRCVD values caused MQ to display incorrect values (value lower than the previous recorded value).
Problem conclusion
MQ code has been modified to display 4294967295 for BYTSSENT and BYTSRCVD when the value exceeds 4294967295. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 LTS 9.1.0.9 v9.2 LTS 9.2.0.2 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
