Have moved these to a cluster resource and am now tinkering, following
the guidelines in TID 10097499 as to what has to change. I note teh
list of files isn't exhaustive, how do I advise the writer of the TID?

The TID doesn't refer at all to the tcadmup and tcadmdn scripts nor
any other sys\system scripts. I presume for consistency these should
also be run off the cluster and modified to refer to the cluster

Can't say I like the additional maintenance and can't say that I like
the delay that loading Tomcat introduces in the resource becoming
usable, and I suspect I'll revert to loading admnsrv and tomcat from
the individual sys volumes.
