When the Tuxedo domain gateway has Data Dependent Routing (DDR) configured with Domains Link-Level Failover, if the primary address contains a host name that doesn't exist in DNS, the domain gateway will fail to connect to the primary address, and will not attempt to connect to secondary remote gateways. The following errors can be seen in the Tuxedo userlog:
074430.mylocal!GWTDOMAIN.19544.4.0: LIBGWT_CAT:1303: ERROR: Network error occurred during connection establishment
074430.mylocal!GWTDOMAIN.19544.4.0: LIBGWT_CAT:1512: ERROR: Unable to connect to remote domain MY_REMOTE_DOM
074430.mylocal!GWTDOMAIN.19544.4.0: LIBGWT_CAT:1037: ERROR: Unrecoverable error occurred on send of data - sending failure reply locally
The Tuxedo client then fails with TPESVCERR.
The problem can happen when a computer is removed from the network. If the host name is removed from DNS, but left in the Tuxedo domain configuration, Tuxedo will attempt to use an undefined host name during connection establishment. The problem can also be caused if you mistakenly configure a host name that is undefined in DNS within a listen address.
