Link Management
Table 1-2 lists the TS/MP 2.3 Pathway Domain Limits.
Link Management
To provide transparent migration from TS/MP 2.0 applications, the ACS subsystem link
management functions use the same program file name (
$SYSTEM.SYSnn.ROUT) and
process name (
$ZLnn) used by TS/MP 2.0. However, because the contents of
$SYSTEM.SYSnn.ROUT are different for each version, the TS/MP 2.3 and later
versions cannot be used in a TS/MP 2.0 environment, and vice versa.
Although there have been changes in server class queuing, it is important that servers
conform to the server packaging guidelines outlined in Section 2, Packaging Server
Functions in the
TS/MP Pathsend and Server Programming Manual. The changes
described in this section are recommended but not mandatory.
Requester send
operation (per
processor)
Maximum outstanding send requests for
all requesters in the processor.
4045 8191
Server classes Approximate maximum server classes
to which all requesters in a processor
can have outstanding sends. The exact
number depends on the current memory
utilization.
4045 4045
Max Pathway
Domians
Maximum Pathway domains that can be
configured in a system.
255 255
Note. When both TS/MP for NonStop Tuxedo (TROUT) and TS/MP 2.x are installed on a
system, two link manager processes run on the system. The TS/MP 2.x link manager process
runs as $ZLnn using the $SYSTEM.SYSnn.ROUT executable file.The TS/MP for NonStop
Tuxedo link manager process runs as $ZTnn and uses the executable file
$SYSTEM.SYSnn.TROUT. On such systems, the limits applicable for TS/MP for NonStop
Tuxedo are the same as for TS/MP 2.0.
Table 1-2. TS/MP 2.3 Pathway Domain Limits
Parameter Limit
Number of PATHMONs per Pathway domain 4
Number of Pathway domains 255
Note. In TS/MP 2.3, the Pathway configuration limits are increased up to 4x because four
Pathways can together form one logical Pathway environment.
For example, MAXSERVERPROCESSES is raised from 4096 to up to 16380.
