TS/MP 2.5 System Management Manual

C Configuration Limits and Defaults
Table 13 (page 318) lists global limits for various items within each Pathway environment.
NOTE: These limits are subject to change with product SPRs or with new software releases. For
information on TS/MP 2.5 limits, see the TS/MP 2.5 Release Supplement.
Table 13 Global Pathway Environment Limits
Limits Per Pathway EnvironmentItem
8191 for all server classes.ASSIGNs
Internal table limit of 64 KB for total of named components (server classes, server processes,
ACS subsystem processes, ASSIGNs, PARAMs, and Pathway/iTS TCPs, TELL objects, and
TERM objects) within a Pathway environment.
Components
Internal table limit of 8 KB for each of the following within a Pathway environment: server
classes, server processes, ASSIGNs, PARAMs, DEFINEs, and Pathway/iTS TCPs, TELL objects,
and TERM objects.
One per processor.LINKMON processes
PATHMON processes:
Maximum of 256 Pathway environments with which a ACS subsystem process can
communicate.
Server classes:
Maximum of 1024 server classes to which a ACS subsystem process can have outstanding
links across all Pathway environments.
Links to server processes:
Maximum of 1750 concurrent links to server processes across all Pathway environments, per
ACS subsystem process.
Maximum concurrent links to the same server process, per ACS subsystem process, is the
value of LINKDEPTH.
Concurrent Pathsend operations:
Maximum of 1600 concurrent, outstanding Pathsend calls per ACS subsystem process.
Pathsend requestors:
Maximum of 1024 concurrent Pathsend requestors per ACS subsystem process.
Only one SCREEN COBOL program at a time can use a link (by performing a SEND).Links
Only one Pathsend process at a time can use a link.
For a description of how to calculate the number of links a link manager might require for a
given server class and the number of links a given server class is able to provide, see
“Configuring Links for Optimum Performance” (page 66).
One (or one process pair) per Pathway environment.PATHMON process
One (or one process pair) per Pathway environment.PATHWAY object
Maximum number of concurrently running processes (ACS subsystem, PATHCOM, SPI, and
Pathway/iTS TCP and external TCP,) must not exceed 800. (Although more than 150 can
be configured, no more than 800 can run concurrently.)
Requestors
Maximum number of requests from a requestor to the same server process is 255 or the value
of LINKDEPTH, whichever is smaller.
Maximum of 255 concurrent, outstanding send requests per Pathsend requestor.Pathsend requestors
Maximum of 4095 supported by each PATHMON process; suggested maximum of 4094
to avoid error 1102.
SERVER objects
For information on the number of links to a server class, see the discussion earlier on links.
Table 14 (page 319) lists each PATHCOM parameter that has a value range or limit, its
corresponding SPI token or field name, its value range, and the default value. This table is organized
