Ann,
 Thanks for the info. I could not do a LISTC on the cluster because it never 
got created due to the catalog error. No matter, I went into the ACS routines 
and did modifications needed for the DATACLASS that I wanted to use. I was 
under the mistaked impression that I could get by without making those mods. 
Bottom line here is that once I updated the ACS routines, validated them, and 
put them online, I was indeed able to create the cluster.
a BIG thank you to the isters that have responded to my question.
Regards,Bill J.

 Bill, 

The DATACLAS and STORCLAS routines are always driven in allocation (well, 
almost always).  The STORCLAS routine must make a null STORCLAS assignment in 
order for the data set to be non-SMS managed.  

If it were me, I'd scale back the space allocation as an experiment and see 
what happens on the allocation.  That can provide a clue as to what issue 
really needs to be resolved.    

HTH,

Subject: Re: RES: VSAM question

OK there has been an email trail on this but I believe I was not clear in my 
explanations. It is my understanding that I can define VSAM clusters using a 
DATACLASS parameter that specifies extended format as the dataset type and 
extended addressability in order to get past the 4 gig limitation without 
having the cluster under SMS management. 

Now, I updated the DATACLASS interactively in ISMF and after running a SMS 
update. it now shows that it has EXTENDED in the datasettype and extended 
addressability set to YES. I then attempt to define the cluster but I am 
getting that reason code of 110 in the define job.  If SMS updated the 
dataclass, as I have indicated, why would ACS routines even be involved here?
