Sure - but these are the settings:
SPACE PRIMARY(10)
SECONDARY(10)
DIRECTORY(0)
MEASURE(TRK)
PRIM_ORG(ALX)
NORLSE
UNIT NAME(SYSALLDA)
So I'm reading that as equivalent to SPACE=(TRK,(10,10)) by default, very
different to the 45K tracks we saw yesterday. We have no EXITxx members.

That means you are taking defaults. So the Init and Tuning Reference will
provide more info
ALLOCxx (allocation system defaults)
Use the ALLOCxx member of SYS1.PARMLIB to define installation defaults for:
Unit names (dynamic allocation, unit-affinity-ignored, and redirection from
TAPE)
Space attributes
TIOT size
Handling allocation requests
Catalog error policies.
These installation defaults for handling allocation requests can be overridden
by installation exit routines specified in the EXITxx parmlib member. For
information about the allocation exit routines, see z/OS MVS Installation
Exits. After IPL, use the SETALLOC command to change any of the defaults
(except for 2DGT_EXPDT).
