ACS Subsystem Components
Domain Coordinator Process ($ZACS)
The domain coordinator process is the ACS subsystem manager process. One instance of this process
occurs in a system; it coordinates and manages the ACS domain resources configured for the subsystem.
It also creates the initialization file (BCINI) which contains the ACS subsystem configuration.
Process Broker Process ($ZPnn)
The process broker manages links from TS/MP PATHMON processes for Pathsend requests. The name
of the process is $ZPnn, where nn is the number of the CPU in which the process is running.
Configuration Subscriber Process ($ZCSnn)
The configuration subscriber process publishes critical ACS subsystem configuration information to the
other ACS subsystem processes. The name of the process is $ZCS nn, where nn is the number of the
CPU in which the process is running.
Redirector (ROUT) Process ($ZLnn)
The redirector process performs link management functions similar to those performed by the former
TS/MP LINKMON (ROUT) process. To simplify application migration, the redirector process uses the
same program file name ($SYSTEM.SYSnn.ROUT) and process name ($ZLnn) used by the TS/MP 2.0
ROUT process; where nn is the number of the CPU in which the process is running. See Figure 2-1 in
Chapter 2 for an overview of the redirector process in a Pathsend environment.
For each request from the Pathsend library, the redirector process performs the necessary
