- Subject: Esoteric Device Message in ESA 4.2
- Lines: 42
-
- Our shop is in the process of upgrading from ESA 3.1.1 to ESA 4.2, and
- an annoying JES2 message has appeared in some of our ESA 4.2 test jobs.
-
- Here is the situation:
-
- A NONVSAM dataset is created on DASD (assume a 3390) and cataloged in an
- ICF catalog. One can then do an IDCAMS LISTCAT and see the DEVICETYPE
- for the entry. In our shop, DISK is defined as an esoteric, with a list
- of addresses containing both 3380 and 3390 volumes.
-
- If the dataset is cataloged via UNIT=DISK and DISP=(,CATLG) in jcl, the
- catalog shows a DEVICETYPE of X'3010200F'. The same thing happens if we
- catalog the dataset using IDCAMS DEFINE ... NONVSAM DEVTYPE(3390), and
- if we catalog the dataset with a WYLBUR command (apologies to Leonard).
-
- However, if we catalog the dataset using IDCAMS DEFINE ... NONVSAM
- DEVTYPE(DISK), the catalog shows a DEVICETYPE of X'0003200'.
-
- I guess the first question is why is IDCAMS using X'0003200'? However,
- this is also true in our ESA 3.1.1 system, and it does not generate any
- JES2 messages there.
-
- Now in our ESA 4.2 system, the JES2 job log shows the following message
- when a dataset with X'0003200' is encountered:
-
- IEF348I dsname WAS FOUND TO BE CATALOGED USING ESOTERIC DISK
- INSTEAD OF A GENERIC
-
- The ESA 4.2 messages manual says that this is to warn the user in case
- the system I/O configuration changes. The manual seems to be advising
- the systems programmer to recatalog the dataset using a generic. In
- our shop the systems programmer does not mess around with application
- files. Anyway, it would be a never-ending task, since we recommend to
- our application staff that they use esoterics rather than generics.
-
- Fortunately, only a few files are affected by this, because most of our
- files are cataloged in jcl rather than by IDCAMS. However, I wonder if
- anyone else has encountered this problem and found a way to suppress the
- JES2 message. Is there some reason why JES2 should be giving people
- this "reminder" every time they access a file cataloged with IDCAMS and
- an esoteric? It seems like nagging. Is this message a result of the IBM
- orientation toward SMS? We are not yet an SMS shop.
