I have modified our IEFUSI in our shop to increase the number of dataspaces
allowed - sub word 1:
Word 7 The address of a four-word area containing IBM-supplied default
values for data spaces, hiperspaces, and data sharing (through
the
IARVSERV macro). These defaults apply only for programs running
in problem state with user keys. The number of sharing pages,
address spaces, data spaces and hiperspaces can be limited only
for jobs running in user keys and in problem state. Jobs
running in
system key (0-7) or in supervisor state may use unlimited
sharing
pages, data spaces and hiperspaces. The words are defined as
follows:
Sub-word Contents
1 Default data space and hiperspace size. It is
specified in blocks of 4K bytes and must be in the
range of 1-X'00080000'. The IBM-supplied default is
956K (X'000000EF' x 4K).
<<<<< Ive increased this max
2 Maximum combined size for all user key data
spaces and hiperspaces that are created by
application programs owned within an address
space (in megabytes). The IBM-supplied default
and the maximum that can be specified is (2**24)-1
megabytes.
3 Maximum number of user-key data spaces and
hiperspaces created by application programs that
can exist at any given time for an address space.
The IBM-supplied default and the maximum number
that can be specified is (2**32)-1.
4 Maximum number of source and target shared
pages that can be used at one time by problem
state callers using the IARVSERV SHARE services.
The IBM-supplied default is 32 (which allows at
most 16 pages to be shared with 16 other pages;
the number of pages include source plus target).
The maximum you can specify is (2**31)-1.
My question is there a control block I can look at to verify? I've verified
things like REGION, MEMLIMIT.. etc in LDA and RAX data areas. Ive used Marks
RXSTOR64 to verify things also, but not for dataspaces/hiperspaces. Is there
such a thing?
Thanks
