Re: [ptp-user] re: Changing connection name for a remote project
|
Chris
If I change the hostname in the connection properties in the remote system
view, then I can open the project on the second system. This seems to work
if I leave the project open while I disconnect, change the hostname in the
connection, then connect to the second system, but I didn't test this
extensively.
I didn't realize that I could modify the connection's hostname until you
mentioned it. I had made the association between connection name and
hostname, thinking they were fixed, possibly since when I first create a
connection and fill in the hostname, the connection name automatically
fillls in with hostname.
This still seems a little complicated and a subtle aspect of moving to a
different host. Is there any way to make this easier to change in RDT? Is
the hostname outside RDT's scope, where RDT only understands connection
names?
I think there is a problem if a header file exists in different locations
on the two systems then definitions are only fond in the header where they
exist on the first system. For instance, the mpi.h header exists in
/usr/lpp/ppe.poe/include on AIX and /opt/ibmhpc/ppe.poe/include on Linux.
If I create the project on AIX, then I seem to be able to find the
definitions for types like MPI_Comm. If I move to the Linux system, I
don't find the definition. Is indexing information for a project cached
and updated only when files are created, deleted or changed?

Right now RSE doesn't give us notification when a connection is renamed,
which means RDT can't react to it.

We have thought of this... which is why the service model allows for
multiple service configurations per project. However there is no UI yet
to allow you to do this.

Ok... then change the machine the connection points to, but leave the
connection name as it is, and it should work.

As long as you keep the connection name in RSE the same, you should be
able to muck with the actual connection parameters, regardless of the
open/closed state of the project, and it should work.
