TS/MP 2.5 Management Programming Manual

A Configuration Limits and Defaults
Table 33 (page 372) lists global limits for various items within each PATHMON environment.
NOTE: These limits are subject to change with product SPRs or with new software releases.
Table 33 Global Pathway Environment Limits
Limits Per PATHMON EnvironmentItem
8191 for all server classes.ASSIGNs
For Pathway limits with ACS subsystem processes for TS/MP 2.5, see TS/MP 2.5
Release Supplement.
ACS subsystem processes
Internal table limit of 64 KB for total of named components (server classes, server
processes, ACS subsystem processes, ASSIGNs, PARAMs, and Pathway/TS TCPs,
TELL objects, and TERM objects) within a Pathway environment.
nl
Components
Internal table limit of 8 KB (for TS/MP 2.5) for each of the following within a Pathway
environment: server classes, server processes, ASSIGNs, PARAMs, DEFINEs, and
Pathway/TS TCPs, TELL objects, and TERM objects.
Only one SCREEN COBOL program at a time can use a link (by performing a SEND).
nl
Links
Only one Pathsend process at a time can use a link.
nl
For Pathway limits with ACS subsystem processes, see the TS/MP 2.5 System
Management Manual. For a description on how to calculate the number of links a link
manager (that is, ACS subsystem processes) might need for a given server class and
the number of links a given server class is able to provide, see the TS/MP 2.5 System
Management Manual.
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 processes,
PATHCOM, SPI, and Pathway/TS TCP and external TCP ) must not exceed 800.
(Although more than 800 can be configured, no more than 800 can run concurrently.)
nl
Requesters
Maximum number of requests from a requester to the same server process is 255 or
the value of LINKDEPTH, whichever is smaller.
Maximum of 255 concurrent, outstanding send requests per PathSend requester.PathSend requesters
Maximum of 4096 supported by each PATHMON process; suggested maximum of
4094 to avoid error 1102.
nl
SERVER objects
In a COBOL server, the RECEIVE-TABLE size must be equal to or larger than the value
of MAXLINKS; suggested size is larger than MAXLINKS to allow for future increases
in the configuration without having to recompile.
nl
For information on the number of links to a server class, see the discussion earlier on
links.
Table 34 (page 373) lists:
• Each PATHCOM parameter that has a value range or limit.
• Corresponding SPI token or field name.
• Default value.
This table is organized alphabetically, by PATHCOM parameter. These limits and defaults are
subject to change with product SPRs or with new software releases.
SPI tokens and fields are used in the Management Programming interface to PATHMON
environments.
