ExitPDArea (MQBYTE48)

 

Problem determination area.

This is a field that is available for the exit to use, to assist with problem determination. The field is initialized to MQXPDA_NONE (binary zero) before each invocation of the exit function. The exit function can set this field to any value it chooses. When the exit returns control to the queue manager, the contents of ExitPDArea are written to the trace file, if tracing is active.

The following value is defined:

MQXPDA_NONE

No problem-determination information.

The value is binary zero for the length of the field.

For the C programming language, the constant MQXPDA_NONE_ARRAY is also defined; this has the same value as MQXPDA_NONE, but is an array of characters instead of a string.

The length of this field is given by MQ_EXIT_PD_AREA_LENGTH. This is an input/output field to the exit.
