Hmmm.... I have MEMLIMIT(00006G) coded in SMFPRMxx. Here's a few entries
from SDSF:
NP JOBNAME it StorCrit RptClass MemLimit
*MASTER* NO STCDEF 16383PB
PCAUTH NO PCAUTH
XCFAS NO XCFSTC 16383PB
GRS NO GRSSTC 64PB
SMSPDSE NO STCDEF
LLA NO LLA 6GB
The address spaces which SDSF displays as 16383PB correspond to NOLIMIT in
Mark Zeldon's REXX exec, and address spaces which SDSF displays as (blank)
under MemLimit correspond to 0M in the REXX exec.
The maximum theoretical 64-bit address space is 16 exabytes (EB).
Mathematically, that *should* be 16,384 petabytes (PB) or 16,777,216
terabytes (TB). (For those of you that prefer SI notation, please
mentally substitute EiB, PiB, TiB, etc.)
In (E)JES I see the following values, depending on how wide I make the
MemLimit column:
|Cmd JobName ACPU% MemLimit ExCP-Cnt
|<-- --------/------ -------- ---------
| *MASTER* .08 16,384PB 11,135
| PCAUTH .00 16
| RASP .01 2
| TRACE .00 60
| DUMPSRV .00 16,384PB 5,345
| XCFAS .19 16,384PB 502,728
| GRS .07 65,536TB 24
|Cmd JobName ACPU% MemL ExCP-Cnt
|<-- --------/------ ---- ---------
| *MASTER* 1.06 16EB 11,136
| PCAUTH .00 16
| RASP .01 2
| TRACE .00 60
| DUMPSRV .00 16EB 5,345
| XCFAS .24 16EB 502,784
| GRS .07 64PB 24
|Cmd JobName ACPU% MemLimit ExCP-Cnt
|<-- --------/------ ------------ ---------
| *MASTER* .06 16,777,216TB 11,136
| PCAUTH .00 16
| RASP .01 2
| TRACE .00 60
| DUMPSRV .00 16,777,216TB 5,345
| XCFAS .35 16,777,216TB 502,784
| GRS .03 67,108,864GB 24
It's strange how SDSF agrees that the GRS limit is 64PB but disagrees
about 16EB being 16EB. (Could they be using floating point for this?)
Though it may seem like a small error, 16,383PB is actually a *lot* less
than 16EB. A one PB difference is 1,024TB or 1,048,576GB!
Maybe the answer is for everyone to just to report NOLIMIT like Mark Z
does. Then we'll all be in agreement. ;-)
