Can a Pdse be multivolume? I had a PDSE defined in my system , it had taken 5 extents and still growing. There is no space for the PDSE to grow in the volume.

What did you find when you looked in manuals, googled, brought it to the attention of your storage people?

All I know is a Library cannot be multivolume. But when i tried the Idcams Alter / addvolumes . It didnot show me any error and its not taking another extent too.

So i advised the Library user to delete obsolete members.

How large is the PDSE? How many members does it have?

Well, looking back at his posts, you could be right :-) Should be good at manuals then. Maybe the other volume could come into play if you dumped it to tape and restored, but still only use one for the space. I'm guessing. I will stop now, not my territory :-)

The library has currently taken 3,260 cyls and the secondary is defined as 100 cyls. The library is sitting on a Mod-3 volume. I just have another 70 cyls left in that volume..
There are around 1500 members

Its a listing library of a Debug tool, whenever a programmer/user opens a module for debugging a member gets created. This is what i learnt from the users
The issue is resolved now after deleting obsolete members.

My primary concern is, can PDSE be multivol? As far as i know it cannot, But why the idcams alter command ended with no errors.

Why not create a very small PDSE giving a multivolume allocation, keep adding members and find out for yourself what happens.

Tried,
Code:

//STEP10  EXEC PGM=IEFBR14                               
//DD01      DD DSN=WELLS.PDSE,                         
//             DISP=(NEW,CATLG,DELETE),                   
//             UNIT=(DASD,3),SPACE=(CYL,(2,1)),           
//             DCB=(LRECL=80,BLKSIZE=0,DSORG=PO,RECFM=FB),
//             DSNTYPE=LIBRARY                           


Error:
IGD17293I DATA SET WELLS.PDSE HAS             
PARTITIONED ORGANIZATION AND IS NOT ELIGIBLE   
TO BE A MULTI-VOLUME DATA SET, ALLOCATION FAILED

3.2 also resticts creation to single volume.
So I assume it cannot be multi volume.

that' s something that people asking here do not have ( curiosity and ingenuity )
but on the other side the amount of laziness is amazing icon_cool.gif

many, I dare to say, almost all people providing answers and above all code snippets
do it because they are CURIOUS
if those asking had the same curiosity and ingenuity
most probably the forum traffic would be almost non existent

Thanks Guys for the enlightment !!!! , I tried it .
This is what i did -
I created a PDSE library , added a few members in it.
Did Idcams alter to add volumes ( ALTER / ADDVOLUMES(*) )
The Library was shown as multivolume in 3.4
Put in more members , it was taking extents all in the same volume.
Finally reached 123 extents and thrown me E37-04 which says :
Quote:

04 A data set opened for output used all space available to or on
the current volume, and no more volumes were available. Change
the JCL to specify more volumes.


2. For a partitioned data set on a direct access volume or for
a VIO data set, all space was filled when the program
attempted to write another record. (A partitioned data set
or a VIO data set can reside on only one volume with a
maximum of 65535 tracks.)

PDSE's can't be multi-volume, but can have up to 123 extents on a volume. The max size I seem to recall is ~3.7GB which is probably the old 65k tracks per volume limit.

Laziness, when accompanied by curiosity and ingenuity, can be a good thing. It drives to you find better ways to do your work instead of always doing it the hard way. icon_cool.gif

Yes. I'm not sure laziness is the right word in this case, but I also can't come up with a better one. The purely lazy will type one character data-names, because that is "easier" and needs no thought (at that point). The trouble comes later, when the resultant program written by the lazy costs five times the amount of maintenance time.

Instead, the truly-lazy-not-sure-of-the-right-word will find out how the editor works. Will end up probably actually typing few characters, whilst producing a program that is not obviously written by someone who was lazy.

Will also copy code that works, rather than one-letter-at-a-time from scratch. Etc.
