Tuxedo Message "LIBGWT_CAT:1572: INFO: Duplicated Connection To Remote Domain" On INCOMING_ONLY Configured Gateway (Doc ID 1058334.1)

Last updated on JUNE 01, 2017

Applies to:

Oracle Tuxedo - Version 9.0 and later
Information in this document applies to any platform.

Symptoms

During a period of network instability, experienced the known connect-over-connect scenario in which an ON_STARTUP configured gateway(a Tuxedo GWTDOMAIN process) connects to an INCOMING_ONLY gateway multiple times without an intermediate disconnect. Usually caused by a firewall that drops the connection on one side only.

It shows up in the Tuxedo ULOG like this:

113010.abcdef!GWTDOMAIN.25098.1.0: LIBGWT_CAT:1553: INFO: New connection from domain <domain122> accepted, drop old connection!


While the network instability was happening, one occurrence of this message in the ULOG:

112936.abcdef!GWTDOMAIN.25098.1.0: LIBGWT_CAT:1572: INFO: Duplicated connection to remote domain <domain122>, drop new connection!


The strange message above is coming from the INCOMING_ONLY configured side(that is to say, configured in the Tuxedo domains configuration file), very close to the other usual connect over connect messages for the same remote domain.

The online doc says this for the message:

1572
      INFO: Duplicated connection to remote domain <domainname>, drop new connection!
Description
      The GWTDOMAIN got duplicated connection to remote domain.
Action
       Contact BEA Customer Support.
