ZCMK Maps
ZVIRTUAL
records the amount of virtual memory (in bytes) originally reserved for the memory
pool. This value is specified by the DATAPAGES startup parameter, multiplied by
2048. For nonextensible pools, this value is equivalent to the value in the
ZCONFIG field.
ZDATAPAGES
records the number of data pages specified when the segment was created. This
can differ from the value specified by the DATAPAGES startup parameter because
the process can internally adjust the number of pages originally specified by
DATAPAGES. This value applies to the general extended segment of the process.
ZEXTENSIBLE
indicates whether the segment is extensible (TRUE) or not (FALSE).
ZCMK-MAP-STATS-MEM
This map is returned in STATISTICS and RESETSTATS responses to provide
statistical information describing the use of general extended memory by the process.
A RESETSTATS command resets only the ZFAIL, ZMAX, and ZRESET-TIME fields.
ZCMK-MAP-STATS-MEM is based on ZCMK-DDL-POOL-STATS:
For a description of this structure, see ZCMK-MAP-STATS-BUF on page B-30.
ZCMK-MAP-STATS-OPNR
This map is returned in STATISTICS and RESETSTATS responses to provide
statistical information about the openers maintained by the process. All openers are
counted, whether they are using the management interface or an application interface.
The current count must always be at least 1 because the command that retrieves this
information must be conveyed on an open file.
