The report lists coupling facilities in use by the local
system that are "over committed" in their real storage space assignments
to allocated structures. The report is generated as part of CHECK(IBMXCF,XCF_CF_STR_MAXSPACE).
When
the check is run in verbose mode, all coupling facilities in use by
the local system will be included in the report.
The
following information is listed in the report:
For
each CF:
- The coupling facility name.
-
Total dump space defined to the coupling facility.
-
The sum of maximum structure sizes for allocated structures.
-
An indicator as to whether the coupling facility has over committed
on its assignment of real
storage to allocated
structures.
For each allocated structure:
- The structure name.
- The requested maximum
structure size defined for the structure.
-
The estimated maximum augmented space needed to support the maximum
SCM that the coupling
facility assigned
to the structure.

Total Space: (total space)

The report
lists coupling facilities in use by the local system that are "over
committed" in their real storage space assignments to allocated structures.
The report is generated as part of CHECK(IBMXCF,XCF_CF_STR_MAXSPACE).
When
the check is run in verbose mode, all coupling facilities in use by
the local system will be included in the report.
In the report:
- cfname
- The name of the coupling facility processed by the check.
- total space
- The total real storage space available to the coupling facility
for control space, dump space, and structure space. An asterisk (*)
will indicate whether the coupling facility has over committed on
its assignment of real storage to allocated structures.
- dump space
- The total dump space defined to the coupling facility.
- sum of mss
- The sum of maximum structure sizes for allocated structures.
- sum of augmented
- The sum of maximum augmented space for allocated structures.
- strname
- The name of an allocated structure using SCM, and the structure
status. If no status follows the structure name, then only one instance
of the structure is allocated. The status can be one of the following:
- OLD
- A structure rebuild process is in progress and two instances of
the structure are allocated. This is the old instance of the structure.
The structure rebuild process type is either rebuild or duplexing
rebuild.
- NEW
- A structure rebuild process is in progress and two instances of
the structure are allocated. This is the new instance of the structure.
The structure rebuild process type is either rebuild or duplexing
rebuild.
- maxsize
- The maximum structure size.
- augmented
- The estimated maximum augmented space needed to support the maximum
SCM that the coupling facility assigned to the structure.
