TS/MP 2.5 System Management Manual

Resolving the equation yields a MAXLINKS value of 1, which means that in this sample configuration,
each server process can have just one link to a link manager at a given moment; and 120 server
processes can run at any one time. Thus, the configuration provides for a maximum of 120 links,
adequate to support the 120 links required.
Note that if common sense tells you that the value of MAXLINKS is too high in relation to the value
of MAXSERVERS, you must increase the value of MAXSERVERS and allow MAXLINKS to decrease.
Consider a hypothetical configuration including these values:
500 TCP links required250 =
MAXSERVERS=2
This hypothetical configuration works on paper, but in a production application, up to 250 requestor
processes could be attempting to share the services of 2 server processes, leading to many
concurrent, outstanding requests to the server class. A rule of thumb to follow is that the value of
MAXSERVERS can range from the result of the formula in Step 6 up to the total number of links
required (from Step 7). For the hypothetical configuration above, this rule of thumb indicates you
could consider increasing the value of MAXSERVERS to a number up to 500.
Step 9 Adjust Values for COBOL Servers
This step adjusts the values in Step 8 based on whether your application includes COBOL server
classes. For COBOL server classes, the value specified in the RECEIVE-TABLE OCCURS clause must
be greater than or equal to the number specified for MAXLINKS. If you find that the value for
MAXLINKS is greater than the value in the RECEIVE-TABLE OCCURS clause, ignore the results of
Step 8 and do these:
1. Set MAXLINKS to the RECEIVE-TABLE OCCURS value
2. Calculate MAXSERVERS using this formula:
----------------> from formula in Step 7no. of links requiredMAXSERVERS =
MAXLINKS
using values from Step 8 for MAXSERVERS and no. of links. Then adjust MAXSERVERS
up until you get a MAXSERVERS value that, when inserted into the formula from Step 8:
=
no. of links required
MAXLINKS
MAXSERVERS
yields a value for MAXLINKS that equals the value of RECEIVE-TABLE in formula A.
Step 10 Identify Additional TCP Attributes
If your environment includes the Pathway/iTS product, you can perform this final step to identify
additional key TCP attributes.
Use the value for the PATHWAY MAXSERVERCLASSES attribute as the value for the TCP
MAXSERVERCLASSES attribute.
Use 50 as the value for TCP MAXTERMS (as in Step 2).
Use this formula to calculate TCP MAXSERVERPROCESSES:
