Removal of Gateway daemon resource parameters
This information details changes to the Gateway daemon resource parameters that was introduced in CICS® Transaction Gateway for IBM® z/OS® Version 7.1.
The uowvalidation parameter is longer supported. This means that LUW tokens are validated so that they can be used only from the client application connection from which the LUW was started.
If the uowvalidation parameter is specified in the configuration file, the Gateway daemon fails to start. You must remove the uowvalidation parameter from the configuration file.
If any of your applications rely on the uowvalidation parameter being turned off, the application receives the ECI_ERR_LUW_TOKEN error when trying to use the LUW token on a connection, to the Gateway daemon, that did not start the LUW.
