Pathway Domain Configuration Management
3. The ACS subsystem recognizes that the send request from requesters (Client1,
Client2) is being sent to a Pathway domain and hence grabs a link (server
process) from any one of the available PATHMON processes,
$PM1 or $PM2.
4. When one of the participating PATHMON processes (for example,
$PM1 for domain
%env1) is brought down for a Pathway configuration change, the ACS subsystem
automatically redirects the new and queued requests to the other PATHMON
process (
%PM2) within the same domain (%env1) to maintain application
availability.
Pathway Domain Configuration Management
TS/MP 2.3 and later versions provide a new management interface called the Pathway
Domain Management Interface (PDMI), with the set of commands to help configure
and operate multiple PATHMON processes under a single Pathway domain or manage
Pathway domains. The PDMI interface is a superset of the existing PATHCOM
interface where all the existing PATHCOM commands are supported. However, unlike
the existing PATHCOM interface, PDMI has the capability to communicate to multiple
PATHMON processes simultaneously so that the same set of PATHCOM commands
can be run for multiple PATHMON processes.
