Starting with the release of IBM MQ v8.0, IBM included a new header file called: cmqstrc.h. The file description says: This file provides mappings between MQI constant values and string versions of their definitions. In the cmqstrc.h file, from IBM MQ v9.2, there are 342 subroutines for looking up the various integer values and returning […]

On StackOverflow, someone asked a question about determining when a queue’s current depth is the same as maximum depth. They were trying to do it from a script. While this is probably possible (I’m not a sed and/or awk guy), it seemed to me that they are trying to squeeze a fully blown up balloon […]

Java’s Missing Byte Array Class
