Many thanks to those who responded to my question about
how to integrate application monitoring into ASE.
SUMMARY: Yes it is true that ASE does not currently provide
for an extensible mechanism that will monitor applications
and detect application failure as opposed to hardware/network
failure. However, DEC is apparently planning to add this to
ASE. For now, using PolyCenter System Watchdog with scripts
that invoke asemgr commands or using home grown check scripts
that monitor and invoke asemgr commands appear to be the
appropriate solution.
