(1) Is this what you are looking for..........(JES2 Initialization
Dataset Checker)
https://www.ibm.com/support/knowledgecenter/SSLTBW_2.3.0/com.ibm.zos.v2r3.hasa300/dscheck.htm
(2) It does depend on the error. In my experience with changing
JES2 init parms, a syntax error can cause JES2 to issue an error message along
with a WTOR asking for the correct values or to ignore the error. JES2
initialization waits in these cases for a response to the WTOR.

Subject: JES2 parm change - how make sure it's right?
[[ SEI WARNING *** This email was sent from an external source. Do not open

Humor me. I'm an experienced developer playing newbie sysprog in my spare time.
I've got a JES2 system where I want to change the order of job classes for some
of the initiators. I could get professional help but it is a service bureau so
that involves opening a ticket, dollars, etc., etc.
I have done it through SDSF and all is well. I now want to make the change
persistent. I have JES2PARM open in an editor. I can make the changes *very
carefully*.
Questions: (1) is there any way to test it, particularly that I have not fouled
it up terribly? The next IPL is probably months away, and a failure would be
very unpleasant. Is there any sort of non-disruptive "TYPRUN=SCAN"
sort of option to get JES2 to say the parm file is or is not okay?
(2) alternatively, what would happen if it were bad? Suppose I fat-fingered a
comma? Unusable system? I am not sure what I am looking at but it looks to me
like TCPIP and TCAS are running under JES2.
Thanks much,
Charles
