Today when one of the team(batch) pointed me out that vendor has come
with saying that they don't have complete dump and Batch requested to
make the changes in the automatic dump capturing process I had to go
back again for process and could not figure out where and how the
space is getting allocated for these datasets...
Here's my observation while doing investigation :-
1. Status of our dump dataset
IEE852I 02.13.47 SYS1.DUMP STATUS
026
SYS1.DUMP DATA SETS AVAILABLE=002 AND
FULL=000
CAPTURED DUMPS=0000, SPACE USED=00000000M, SPACE
FREE=00005000M
AUTOMATIC ALLOCATION IS:
ACTIVE
AVAILABLE SMS CLASSES:

EXAMPLE=SYS7A.DUMP.S1X01.D100714.T021347.N00000
SYS1.DUMP AVAILABLE DASD DATA SETS :
10-11
Shows the dataclass=DCEXTSP which I thought responsible for allocating
Primary and secondary space ..However that's not true since these are
not defined in our environment.

2. Now I tried with the test console dump for one test job and below
is output and screen shot..

No where I could find any answer how the space is defined for the
SYS7A.DUMP.** datasets.. I presumed since dataclass=dcextdmp point to
storage group SGDUMP which is having 4 volume defined ..my SVCDUMP
dataset would try to extend to all these 4 volumes and acquire all
space ..However these all are 3390-3 model and I see our process of
clearing the dump dataset is also pretty fast to avoid situation where
volumes are filled as soon as other svcdump request kicked on..
Can someone point me out to the manual/redbook which talk about
process of space allocation here...
Also fyi ..i have seen for the message which says PARTIAL complete
could not see that either..
