heartbeat
You can specify an optional heartbeat action for the application specified by
app-nam e. You can use this feature to send an indication to the host that a
session is still active. Some hosts log out sessions that remain idle for a period
of time. You can also use the heartbeat action to check connectivity, verifying
that the session remains on the appropriate screen. Typically, the
heartbeat
action contains a logout-action template which brings the session back to the
login screen if the connectivity with the mainframe fails. If you do not need
a heartbeat action, enter a hyphen for this action.
You specify the heartbeat in this format: actiontemplate@n , where n is the
number of seconds between each execution of the action template when the
session is idle.
The heartbeat action template uses the same syntax as the action templates
described earlier in this chapter, and usually only specifies a single screen
template. That screen template is usually the last screen specified in the
initial-action template. Typically, your screen template would only include a
key-descriptor line, usually the ENTER key and validation-tag .
protocol
The protocol entry indicates the communications protocol being used by
app-name. This field is required and should be set to vt100.
Example “trs.conf” File
Consider the following example. Initial-action template files login.act and
signin.act have been defined and reside in the /u/ivr/3270 directory. There are
four applications which you want to access on the host computer:
• accounting , accesses the accounting software
• market , tracks stock market activity
• banking , retrieves credit balances
• airline , for purchasing tickets on a local commuter carrier
The application names shown here are not necessarily the actual names
assigned on the host computer, but they are the names assigned on the
application processor for the trs.conf file and all action templates that use
these applications.
