GRSRNL xx and No Entry for LSERVDSN and it is there

[Lizette Koehler]

Okay, I am confused by my GRS environment, and I actually thought I
understood about GRS in z/OS better than I apparently do.  So some education
is being requested.

I thought that a GRS resource would not be in the system unless it was
specified in GRSRNLxx.  However, last week by accident I did a display

D GRS,RES=(LSERVDSN,*) and even though this resource name is not in my
GRSRNLxx member, it is in my system with my TPX data sets and Endevor
datasets listed.

I asked CA they said it was normal for TPX to just in case LSERV is
installed, to set itself up this way.

Can someone help me understand how or why you would do this?

I presume that some sort of GRS request is made by the Software (TPX or
Endevor in this case) to establish the GRS resource.  But if I do not put it
in GRSRNLxx is it doing anything I need to worry about?   It is a SYSTEMS
type resource.  Is GRS really in play here?

Thanks

Lizette

The GRSRNLxx member does not put resources into the system, its purpose
is to allow the installation to alter the SCOPE (from ENQ/DEQ/ISGENQ) of a 
request, or if RESERVE requests are to be treated as hardware reserves or
converted into SCOPE=SYSTEMS enqueue requests.

The SCOPE of the request is established by the program issuing the macro.  GRS
RNL processing is available to you to those requests.  See:

Probably not.

Yes.
