RP/TUX 6.5, TUX 6.51 - Use of the first network address on multihomed machines - new environment variable TMUSEFIRSTHOSTADDR

(Doc ID 767330.1)

Last updated on NOVEMBER 04, 2016

Applies to:

Oracle Tuxedo / Tuxedo / 6.5, 6.51
Information in this document applies to any platform

Goal

On machines with several IP addresses and hostnames, the gethostbyname() returns an array containing the different IP
addresses when invoked with the main hostname. Tuxedo picks one of these addresses to perform the bind() listen()
network operations. When trying to bind() to the same port, this can lead to a conflict in some cases.
