An RRS application is already using the same resource manager name (name )
An attempt is made to start a Gateway daemon, but another application is already using the resource manager name supplied. The application could be another instance of the Gateway daemon or a third party product.
The error is logged. If XA support is on, the Gateway daemon fails to start. If XA support is off the Gateway daemon starts but extended logical units of work requests fail.
Correct the configuration and try again. Refer to the CICS® Transaction Gateway Information Center for information on resource manager names.
