Tuxedo JCA: "java.io.IOException: Error: select operation failed for ConnectionContext(null), client disconnect"

(Doc ID 1335890.1)

Last updated on DECEMBER 05, 2016

Applies to:

Tuxedo JCA Adapter - Version and later
Information in this document applies to any platform.


With the following setup:

     OC4J --> Tuxedo JCA Adapter --> Tuxedo

When the J2EE application sends large 4-5MB request to Tuxedo, gateway indicates connection was lost. Smaller sized requests work fine.

The errors below are shown in the JCA log:
