Glossary
Application Cluster Services (ACS) subsystem. An infrastructure used by transaction-
processing middleware products to manage and access server classes.
ACS domain. A defined set of objects (resources) within a single physical NonStop system
that are controlled and managed as a unit by the ACS subsystem.
ACSCTL. The ACS control file is the persistent store of environment configuration data.
client. A process running on in a NonStop kernel environment that uses the Pathsend API
to communicate with a server class. See also requester.
configuration subscriber (CS)process. A process in the ACS subsystem that receives
configuration information and makes it available to the other ACS subsystem
processes.
domain coordinator process. The ACS subsystem manager process that coordinates and
manages the resources configured for the subsystem.
EMS. The Event Management Service is part of the Distributed Systems Management
(DSM) used to provide event collection, logging, and distribution facilities.
environment. A set of objects configured under and managed by a PATHMON process that
monitors and manages a TS/MP application.
free pool. The set of processes associated with server classes, which are managed by the
process broker process.
LINKMON. A TS/MP 2.0 privileged process executing in each processor of a NonStop
system to provide link management to multiple TS/MP PATHMON-defined server
classes. In other versions of TS/MP this process is called ROUT.
nonsensitive command. A command that can be issued by any user or program allowed to
access the subsystem. In other words, a command for which the subsystem does not
impose security restrictions. Nonsensitive commands cannot change the state or
configuration of the objects; they are usually informational commands. See also
sensitive command.
Pathsend API. A set of procedures for performing context-free and context-sensitive
communication with server classes.
PATHMON process. The manager process for TS/MP 2.0 environments.
Pathway Domain. A logical domain having multiple replicated Pathway environments
grouped together.
