RP/TUX 8.0 - Repeated tuxgetenv calls slow down performance (Doc ID 770141.1)

Last updated on NOVEMBER 04, 2016

Applies to:

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

Goal

In tcm.c, for every tuxedo call, tuxgetenv("ALLOW_INTOP") is called. This code was added in one of the later
loads of 8.0, and it slowed down the code path by around 10%.

See line 3338 in tcm.c. There are a couple of things wrong with the code. There are some indented statements below the
'if', but they are not within the 'if' block. Perhaps they were intended to be part of the if.

Tuxgetenv should not be called every time. A process global should be set once, and then tested in the if.
