This is NOT binding in that sense.
I assume it's like SAP: the startsap command gets the system hostname, and
uses that to determine what command to run. The system has to be configured
to run with a specific hostname, so if it changes - because HACMP has
changed the hostname to support a different application - SAP won't start.
It's clearly impossible to have two different hostnames on the same system.
The only way around it I can see is either to configure the application so
that it will work with either hostname, or to use an alias for the hostname,
(or uname or whatever) command, which will generate the desired value.
