VHS Browser
VHS Browser
VHS Browser, the VHS screen facility, enables you to access two important files
created by VHS:
•
VHS primary log file set—contains all the messages received by VHS.
•
VHS prompt file—contains all outstanding (unanswered) prompts received from
applications.
The VHS primary log file set provides an audit trail of the messages received by VHS.
This log or audit trail is actually a set of up to five files. You can specify the primary and
secondary extent sizes and maximum number of extents of the primary log files when
you start VHS. For more information about the VHS primary log file set, see Section 3,
Using VHS.
To view the primary log file set or the VHS prompt file, you access the appropriate VHS
Browser screen. On the Log Browser screen, to view messages from a specific
process or after a specific time, you can specify criteria such as date, time, or process.
This table summarizes the functions of VHS Browser:
Debug prompts VHS sends to Debug the D;T;S (Display;Trace;Stop) commands and
stops the application. VHS logs Debug messages in its primary log
file. VHS can also send EMS events to the collector if configured to
do so (see the GENERATE-INSPECT-EVENT parameter).
Application prompts Saves the prompt to its prompt file. The prompt can be answered via
the Prompt Browser screen. Also sends the event to the collector, if
configured to do so (see the parameter GENERATE-PROMPT-
EVENT), and logs the message.
Reply messages Sends reply messages to the application, keeps a copy of the reply
in its primary log file, and, if configured to do so (see the
GENERATE-PROMPT-EVENT), generates an EMS event.
