TS/MP Management Programming Manual (H06.05+, J06.03+)

Configuration Limits and Defaults
HP NonStop TS/MP Management Programming Manual—540082-005
A-2
Table A-2 lists each PATHCOM parameter that has a value range or limit, its
corresponding SPI token or field name, its value range, and its 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.
Links Only one SCREEN COBOL program at a time can use a link (by
performing a SEND).
Only one Pathsend process at a time can use a link.
For Pathway limits with ACS subsystem processes, see the TS/MP
System Management Manual. For a description on how to calculate the
number of links a link manager (such as LINKMON process, ACS
subsystem processes, or Pathway/TS TCP) might need for a given server
class and the number of links a given server class is able to provide, see
the TS/MP System Management Manual.
PATHMON
process
One (or one process pair) per Pathway environment.
PATHWAY
object
One (or one process pair) per Pathway environment.
Requesters Maximum number of concurrently running processes (LINKMON or 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.)
Maximum number of requests from a requester to the same server
process is 255 or the value of LINKDEPTH, whichever is smaller.
PathSend
requesters
Maximum of 255 concurrent, outstanding send requests per PathSend
requester.
SERVER
objects
Maximum of 4096 supported by each PATHMON process; suggested
maximum of 4094 to avoid error 1102.
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.
For information on the number of links to a server class, see the
discussion earlier on links.
