Abstract

The Generic Alerter service for LAN Server* 2.0 constructed SNA formatted alerts for server conditions as reported by the NetAlertRaise API. The problem for LAN Server 3.0 was to extend service to accommodate requester alerts as reported by the NetErrorLogWrite API as well.

Method for Providing Generic Alert Support for both Servers and Requesters

      The Generic Alerter service for LAN Server*  2.0 constructed
SNA formatted alerts for server conditions as reported by the
NetAlertRaise API.  The problem for LAN Server 3.0 was to extend
service to accommodate requester alerts as reported by the
NetErrorLogWrite API as well.

      To accommodate generic alert reporting from requesters the
module that builds the FFST/2 (First Failure Support Technology)
generic alert control block was removed from the Generic Alerter
service and made into a library routine that can be called from any
other server or requester module.  The detection of ADMIN event
alerts remained in the Generic Alerter service, while errorlog event
alerts would now be detected by the NetErrorLogWrite code.  New code
would be added to the NetErrorLogWrite module to send the alert
information on to the control block generation module.  This posed
the problem now of how to best package the needed information.  A
simple interface accommodates the differences in the data as returned
from ADMIN mailslot messages from the server and from the ERRORLOG
event data from the server/requester.  The FFST/2 message control
block is used since it contained fields for all the data needed for
an alert (mainly the ERRORLOG or ADMIN message number and an array of
all the message insertion text strings).
