TS/MP 2.5 System Management Manual

Table 5 (page 111) lists the ACS core processes and their respective process names and object
names.

Initialization
Unlike the TS/MP 2.0 LINKMON process, the ACS subsystem core processes are initialized as
soon as they are started. The status of ACS core processes on each CPU on the system is logged
in the ACS subsystem log file. The ACS subsystem log file can be set while configuring the ACS
subsystem using the SCF commands.
Limits
The ACS subsystem provides higher Pathsend limits per CPU compared to the TS/MP 2.0 LINKMON
process. For more information on ACS subsystem limits, see the TS/MP 2.5 Release Supplement.
Extended Memory
The operating system manages the extended memory requirements of the ACS subsystem. Therefore,
an external swap file is not required.
ACS Subsystem Memory Dumps
Unlike TS/MP 2.0, the ACS subsystem core processes no longer halt the processor in case of
internal product errors. Instead, ACS core processes stop themselves after creating memory abend
files.
NOTE: If one of the ACS core processes on a processor goes down, the remaining core processes
on the same processor also go down. Issuing the SCF CONTROL command can restart the stopped
core process on the processor. For more information about the SCF CONTROL command, see the
TS/MP 2.5 Release Supplement.
Pathsend Management Tasks
To communication between Pathsend processes and server processes, you must configure your
PATHMON environment to specify:
• The number of ACS subsystem processes that your PATHMON environment can support at
one time
• The appropriate security to control access to server classes
You cannot configure or control ACS subsystem processes with PATHCOM commands in the same
way that you control and configure PATHMON-controlled objects. However, you can, monitor the
ACS subsystem processes, as described later in this section.
Specifying the Maximum Number of Link Manager (LINKMON/ACS Subsystem)
Processes
Before starting a PATHMON environment, you specify the maximum number of link manager
(LINKMON/ACS subsystem) processes that the PATHMON environment can support at one time
by setting the MAXLINKMONS parameter with the SET PATHWAY command.
