Currently, we update production programs by simply compiling from
source into the production library. I'd like to move the object from
the test library instead. The trouble is, I need an exclusive lock
on the production object to accomplish this. We run a 24/6 shop, and
I can't wait until Sunday to promote an update. Our current compile
method doesn't suffer from this problem (the current object is moved
to QRPLOBJ and users are pointed there). Is there some way to
replace the production object without the exclusive lock?

The REPLACE(*YES) processing needs the same /exclusive lock/ as any other methods. Thus no matter whether the CRTxxxPGM REPLACE(*YES) is used, the RNMOBJ and optionally MOVOBJ is used, or the Rename and/or Move Object (QLIRNMO) API is used, the program object typically can be locked exclusively during that processing. The reason these operations typically function without a lock conflict, is because a called program is not allocated in order to have been activated; only an explicit lock [e.g. by the application] will prevent others from obtaining the lock required for the rename and move operations.
