It's quite annoying that the number of uncommitted messages is not viewable on z/OS queues (it is on all other platforms).

or the other direction
var2 = TRANSLATE(STRING,LOWER,UPPER)

DISCINT can be set to zero so once it starts it won't disconnect voluntarily.

However this wastes memory in the QM.

It should start automatically if correctly set up.

Use as much memory caching (fast write) as possible.
