Paul,

When you install a second windows service, how do you automate the install of a 
second set of icons into the start menu? I'm struggling with this at the moment

and while I'm asking windows questions :)  (server and client version 5.3.0)

I don't like the Windows MMC interface, and far prefer to use two sessions, one 
for command line entry and the other to watch the log.  I'm rolling out an 
implementation that has a "strategic" and a "tactical" backup server instance 
at each site to a whole new set of green  admins so I'd like to make the set up 
as easy as possible for them. With four open windows on the screen it gets a 
bit confusing as to which is which... When the admin client comes up it 
overwrites the window title with "IBM Tivoli Storage Manager" is there any way 
to change this to something more descriptive?

Thanks

Steve

I have things configured pretty much as you describe, and I also use
dsmcutil to create the services when using a cluster- Way easier to reduce
mistakes since I can throw it into a batch file and run it on both sides of
the cluster.  :)

The issue I'm seeing, though, can be duplicated on a non-cluster.  (however
the results seem to happen on some systems but not others) If you take a
Windows 2000 or 2003 server and try the following:

1. Install a regular dsmcad, agent and scheduler service using the default
baclient\dsm.opt file.
2. create a second options file named something different such as dsm2.opt
3. install a second set of services, named differently, and using the
dsm2.opt, and using a different nodename from the first set.  (ie. you would
use this if setting up a scheduler for an agent perhaps, or for a cluster
resource group).
4. before starting the dsmcad service, start up a console window
(dsmadmc -console)
5. start dsmcad, wait the minute for the scheduler to kick in

What I see on the console (and in the actlog) is:
- an inital connection using the correct (second) nodename, by the dsmcad as
soon as I start the service
- 1 minute later, I see two more client connections as the scheduler
connects.  the first connection uses the wrong (first) nodename, the second
connection uses the correct (second) nodename.

other than that, everything seems to work correctly.....
