Tuxedo Domain Accepted A Remote Tuxedo Domains Connection With Correct Configured Name But Wrong IP Address (Doc ID 1167643.1)

Last updated on DECEMBER 05, 2016

Applies to:

Oracle Tuxedo - Version 8.1 to 11.1.1.1.0
Information in this document applies to any platform.

Symptoms

On Tuxedo 8.1 version:

When attempting to establish connectivity between domains the following error messages occur in the logs:

LIBGWT_CAT:1129: INFO: Connection established with domain (domainid=<rdomid>)

LIBGWT_CAT:1553: INFO: New connection from domain <RDOM1> accepted, drop old connection!

LIBGWT_CAT:1249: WARN: Connect to rdomid address //$HOST:$PORT failed, Network error(245)



STEPS
-----------------------
The issue can be reproduced with the following steps:
1. configure 3 domains A,B,C with A pointing to B
2. B and C are having same domain names even though they are not part of the same environment.
3. now during connection attempts ,as C is defined the same way as B it was able to steal the connection from B (such that A now connects to C) even though A does not have configured anything about C and would not connect to it through it's configuration.
