ACS Subsystem Core Processes
$ZCSnn processes respectively, where nn is the processor number), which are
responsible for all Pathsend requesters executing in that processor. ACS subsystem
core processes acquire links from the PATHMON process that controls the server
class. The ROUT process then shares its links among the Pathsend requesters
executing in its processor.
The ACS subsystem core processes are visible to a PATHMON process but are not
controlled by it. Unlike the TS/MP 2.0 LINKMON process, you can directly configure
and control the ACS subsystem using the Subsystem Control Facility (SCF)
commands. You can use PATHCOM commands to perform various ACS subsystem
related functions. For more information on managing the ACS subsystem and the ACS
core processes, see the TS/MP Release Supplement.
Table 6-2 lists the effects of various PATHCOM commands on the ACS subsystem.
Table 6-2. PATHCOM /PDMCOM Commands That Affect the ACS Subsystem
PATHCOM /PDMCOM
Command Effect on ACS Processes
FREEZE SERVER Prohibits the ACS subsystem from sending requests to
server classes
INFO PATHWAY Displays the current MAXLINKMONS value
RESET SERVER SECURITY Resets the current values for a server class and server
class security
ALTER SERVER SECURITY Alters the current values for a server class and server class
security
SET PATHWAY The MAXLINKMONS parameter sets the maximum number
of ACS PB processes that can communicate with a specific
Pathway environment
SET SERVER SECURITY SECURITY parameters restrict access by Pathsend
requesters to the server classes
SHOW SERVER
INFO SERVER
Checks the current SECURITY and OWNER attribute
values for a server class
STATS SERVER Displays resource usage and performance statistics on
ACS subsystem processes linked to a specific server class
STATUS LINKMON Checks the status of ACS PB processes that have links to
server classes in the Pathway environment
STATUS PATHMON Identifies the ACS PB processes currently communicating
with the PATHMON process
STATUS PATHWAY Determines the number of ACS PB processes
communicating with a Pathway environment
STATUS SERVER Identifies the ACS PB process linked to a specific server
class
THAW SERVER Allows ACS subsystem processes to send requests to
frozen server classes
