RP/TUX 8.0, TUX 8.1 - MP load balancing does not work as documented with service caching enable (Doc ID 774022.1)

Last updated on JANUARY 19, 2018

Applies to:

Oracle Tuxedo / Tuxedo / 8.0, 8.1
Information in this document applies to any platform


Set of 'm' Tuxedo clients calls synchronous service A advertised in a set of n servers with equal number on machines A
and B .
Service A calls service B, then service C.  Services B and C are both advertised in a second set of 'n' servers with
equal numbers on machines A and B.

With service caching enabled (default), calls to services B and C sometimes go across to a remote machine, even though
there is always at least one idle server available on the same machine.  This even happens when NETLOAD is set to its
maximum value.

If service caching is disabled (SICACHEENTRIESMAX=0), this problem does not occur, and load balancing appears to work
as documented.  Customer would however like to able to run with service caching enabled due to its performance

Tuxedo 8.0 RP199/ MP model. Not platform dependent.
