SNAX/XF and SNAX/APN Event Management Programming Manual—426859-001
4-41
26: ZSX1-EVT-MEMORY-ALERT
This token is described in the EMS Manual.
ZEMS-TKN-CONSOLE-PRINT
contains the value ZSPI-VAL-FALSE. This token is described in the EMS Manual.
ZSPI-TKN-MANAGER
is the name of the service-manager process (the SUBSYS object name), as described
in the SNAX/APN Management Programming Manual.
ZEMS-TKN-LDEVNUMBER
identifies the logical device number. This is the 32-bit equivalent of
ZEMS-TKN-LDEV.
ZEMS-TKN-XLDEVNAME
is the string equivalent of the logical device number.
ZEMS-TKN-LDEV
is a standard EMS token described in the EMS Manual.
ZSX1-TKN-MEM-STATE
indicates the level of memory congestion. The possible values are:
ZSX1-VAL-MEM-CONGEST-CRITICAL
indicates that there is severe memory congestion, sufficient to prevent the start
of any new sessions.
ZSX1-VAL-MEM-CONGEST-MODERATE
indicates that there is less severe memory congestion. The congestion is not
enough to prevent new sessions from being started. It can, however, reduce
system performance by restricting new buffer requests.
ZSX1-VAL-MEM-CONGEST-NONE
indicates that there is no memory congestion. This value is returned when the
system exits a previous memory-congestion condition.
Cause. During SNAX/APN operation, the memory manager in the line-handler process
either detected a memory congestion condition or exited a previously existing memory
congestion condition.
Effect. The effect depends on the value of ZSX1-TKN-MEM-STATE:
Note. Although ZEMS-TKN-LDEV is included in the event message, you should use the
ZEMS-TKN-LDEVNUMBER and ZEMS-TKN-XLDEVNAME tokens when writing new programs
to run on D-series systems.
