EMS Event Messages Generated by VHS
VHS-PROMPT-RESEND-DELAY
The VHS-PROMPT-RESEND-DELAY is the time interval (in minutes) at which VHS will
resend the VHS prompt event message when a prompt is unanswered. By default, this
parameter has a value of 15 minutes. The possible value is from 1 to 60 minutes. This
parameter will be ignored if the VHS-GUI-MODE parameter is set to OFF.
VHS handles these two attributes in this manner:
As soon as a prompt is received by VHS, it is available to the VHS GUI.
If you do not answer the prompt, VHS generates the ZVHS-PROMPT-RESEND-
EVENT at each interval specified by the PROMPT-RESEND-DELAY parameter.
The ZVHS-PROMPT-RESEND-EVENT parameter is generated by VHS with the
SUPPRESS-DISPLAY attribute set to ON.
This purpose of this new event message is to prevent the loss of a prompt in case of a
partial network, software, or system failure.
EMS Event Messages Generated by VHS
The behavior of VHS changes when you set the VHS-GUI-MODE parameter to ON.
This parameter overrides the setting of the GENERATE-INSPECT-EVENT,
GENERATE-DISPLAY-EVENT, and GENERATE-PROMPT-EVENT parameters. All
these parameters are set to ON and they cannot be changed via the VHSCI.
As a consequence, every application message received by VHS will be written to the
VHS EMS Collector (by default $0). This new setting generates more EMS traffic to
your operator console, and additional filtering may be necessary.
These five EMS events are generated by VHS when the VHS-GUI-MODE parameter is
set to ON:
•
ZVHS-EVT-INSPECT-EXTENDED
•
ZVHS-EVT-INSPECT-APPL-EXT
•
ZVHS-EVT-INSPECT-SCOBOL-EXT
•
ZVHS-EVT-DEBUG-EXTEND
•
ZVHS-EVT-PROMPT-RESEND
