Hi,
I have a cluster define listed below:
DEFINE CLUSTER-
(NAME(dataset) -
REUSE -
SPEED -
SHAREOPTIONS(2) -
NOERASE -
INDEXED -
KEYS(32 0) -
NOREPLICATE -
RECORDSIZE(500 1000) -
FREESPACE(20 30) -
OWNER(ME)) -
DATA -
(NAME(dataset.DATA) -
CYL(600 200) -
CISZ(16384)) -
INDEX -
(NAME(dataset.INDEX) -
CYL(25 5) -
CISZ(2048))
As you can see the initial allocation is for a primary of 600 CYL. When I actually load the data (IDCAMS REPRO) the primary jumps to 3000 cylinders with 21 extents. We are under an operating system of zOS 1.11.
I've never seen the primary allocation get altered like this before. Any answers?
Thanks. |

| Post the LISTCAT output using the Code button to preserve spacing. |

I lost the listcat for the 3000 allocation, but I tried again this morning and got a 1200 CYL allocation on the primary. That LISTCAT is below,,,,only down to the 3rd extent.

| What you show does NOT indicate the primary space allocation was changed. If you think it was changed, then either (1) the DELETE / DEFINE was run from a library other than what you think, or (2) possibly an SMS parameter changed the value (although I haven't looked to see if this is even possible to change this for a VSAM file). |

The primary allocation shows 600 CYL. On this storage device there are 15 TRKS per CYL. You can see the primary tracks are 18000.
18000 / 15 = 1200 CYL's
Here is another view from ISPF[/code] Data Set Information

| Is it possible that the 18000 number you are seeing is not just for the primary, but rather for the entire VSAM, including extents? In this case, you have 3 extents. Counting your primary of 600 cyl, that's 9000 tracks. Adding your 3 extents at 200 cyl (3000 tracks) each, that's 9000 more tracks, for a grand total of 18000 tracks allocated. |

| I don't think so. If you look at the ISPF Dataset Infor mation page, you see that the total allocation for the file is 5800 CYL and it consists of 41 extents. I did not list the entire LISTCAT output showing the 41 extents. Only the first three showed on the first LISTCAT page. |
