Improved Application Availability

1. The ACSCTL file, provided in the ADD Command during startup of the ACS

subsystem, contains information about two Pathway domains. Pathway domain

%env1 comprises of PATHMONs $PM1 and $PM2 on NonStop system \A and

Pathway domain

%env2 comprises of PATHMONs $PM3 and $PM4 on the same

NonStop system

\A.

2. It is assumed that you have configured the Pathway domains with similar Pathway

configuration for the participating PATHMON processes. For example, the server

class attributes for SC1 is same for Pathway domain %env1 for PATHMON

processes

$PM1 and $PM2.
