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 the following 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.

The following 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

For more information on event messages, see Appendix C, VHS Event Messages of

this manual.

Use of Alternate EMS Collectors

To reduce the number of event messages written to the primary collector $0, and

accordingly the load on this collector, you can use an alternate collector for VHS.
