Jake:
I'm guessing that your user set an expiration date with the JCL EXPDT
keyword. If that is correct, then the following applies to his data set.
The JCL keyword EXPDT, doesn't have the same significance as a
management class expiration date. EXPDT causes the system to protect the
data set against change or deletion without operator authorization. If
an attempt is made to write to or delete an "EXPDT protected" data set,
the operator gets a WTOR message asking for permission to continue
writing to or deleting the data set.
SMS gave a different meaning to "expiration", identifying when a data
set would/should be deleted, not how long it remains un-altered. The
data set CAN be deleted (without confirmation) AFTER its EXPDT date, but
it is NOT expired (deleted automatically) in the SMS sense.

Hola Greg,
"That's a bit confusing to me (and perhaps others, based on the lack of
response) - could you clarify a little what you are asking about?"
Without the management class is it possible to specify expiration date for a
dataset ?, But What i understood from the IBM manual is that it needs
management class for setting expiration period for any dataset. In our shop
one of a user has specified expiration date for his dataset though we have
not set any management class. Could you please clarify

Jake,
I'm not sure the quoted answer you got was worded quite right - the ACS
routines are called when data sets are allocated, so I don't think they
can't be said to "track" anything.
Your original question was: "Does it mean the dataset has taken the
expiration date into account ?"
That's a bit confusing to me (and perhaps others, based on the lack of
response) - could you clarify a little what you are asking about?

Subject: Re: Management Class - expiration of dataset
"the ones without the Management class, would still be tracked via the ACS
routines and there would be routines run via DFS*"
Could you please point me to the fine Manual which speaks more about the
above. This would help me in understanding the best practises and narrow
down the unneccessary Selection of Expiration of dataset by application
programmer.
