Greg, is it possible the parms are shifted? What I mean is that when I test this
//ARSPARM DD *
odinstance=ARCH950
oduser=ODV793
oduserpw=pw1
commitcnt=1
unloadmax=1
I get this:
ARS5024I ARSEXOAM 9.5.0.3 invoked on 09/14/15 16:12:16
ARS5003I odinstance=ARCH950
ARS5003I oduser=ODV793
ARS5003I oduserpw=********
ARS5003I commitcnt=1
ARS5003I unloadmax=1
ARS5013I Control statements processing completed - RC=0 (X'00000000')
But if I shift over the parms to column 1 like this:
//ARSPARM DD *
odinstance=ARCH950
oduser=ODV793
oduserpw=fubars2a
commitcnt=1
unloadmax=1
I get this:
ARS5003I odinstance=ARCH950

ARS5003I oduser=ODV793

Not exactly the same messages you are getting (and I tested on 9.5.0.3) but close
