RP/TUX 6.5, TUX 6.51 - LIBGWT_CAT:2000: Unable to connect to Remote Domain (Doc ID 768850.1)

Last updated on NOVEMBER 04, 2016

Applies to:

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

Goal

The problem happens in a production environment when there is a high load of calls from the local domain to a service
not available at the remote domain.  It seems to happen only with XA services. We couldn't reproduce it with non-XA
services even with a much higher load. The problem occurs always around 32600 calls, even  after increasing MAXGTT,
TLOGSIZE, MAXTRAN, DMTLOGSIZE, ... 
The error message that appears in the ULOG is: LIBGWT_CAT:2000: ERROR: Unable to connect to remote domain.
Until the GWTDOMAIN was restarted, the messages continued to appear.
