(Doc ID 1454733.1)

Applies to:

Oracle Weblogic Server - Version 10.3.4 and later
Oracle Exalogic Elastic Cloud Software - Version and later
Linux x86-64


Connections between WebLogic Tuxedo Connector (WTC) on Exalogic and Tuxedo running on a remote AIX box do not not stay connected.  The WTC domain is configured for ON_STARTUP (with retry) and the Tuxedo domain is configured for INCOMING_ONLY. 

The following errors keep appearing in the Tuxedo ULOG file:

094456.myExaMachine!GWTDOMAIN.23658732.772.0: LIBGWT_CAT:1128: INFO: Connection accepted from domain (domainid=<wtcLocal>)
094456.myExaMachine!GWTDOMAIN.23658732.772.0: LIBGWT_CAT:1130: INFO: Disconnected from domain (domainid=<wtcLocal>)
094456.myExaMachine!GWTDOMAIN.23658732.772.0: LIBGWT_CAT:1354: INFO: Retrying domain (domainid=<wtcLocal>) every 60 seconds


After turning on WTC tracing, the following IOException is seen in the WLS server log on Exalogic:

<BEA-180046> <[/TuxedoMuxableSocket/hasException/java.io.IOException: SocketChannel not available>


 Migrated applications to Exalogic platform.
