A new feature
introduced in the Enterprise manager is the ability
to connect to to multiple Nirvana realms at the same
time. These realms can be standalone or clustered so
developers and administrators can now manage and monitor
the whole Nirvana enterprise infrastructure from a single
instance of Enterprise manager. Once connected to a
set of Nirvana realms, it is possible to save
the connection information so that Enterprise manager
automatically connects to all those realms each time
it starts.
A bootstrap RNAME environment variable is needed the
very first time you run Enterprise manager or if your
connection info file is empty. If you use the shortcut
/ link created by the installation process this will
be automatically set to point to the locally installed
realm's bootstrap interface so you dont need to take
additional action. If however you open a client command
prompt and you wish to initially connect to a realm
other than the local one, then you need to change your
RNAME environment variable. For more information on
how to set the RNAME variable, please see the appropriate
section
in the developer guide. Please also note that once your
realm connection information is saved,
the RNAME environment variable will be ignored.
Once your Enterprise manager is up and running, you
have to select the Connect to Realm menu option from
the Connections menu, as shown in the figure below:
The menu option will open the Connect To Realm dialog
as shown in the figure below:
Simply fill in the RNAME that points to the interface
of the Nirvana realm you wish to connect to and click
on the OK button. The Enteprise manager status bar will
display a message informing you where it is trying to
connect to. If the connection is sucessfull, a new realm
node will be rendered on the tree with the unique name
of that realm. You can manage and monitor the new realm
by selecting that newly rendered tree node.
If you enter an incorrect RNAME, if that realm is not
running or if it is running but the particular interface
is not up the connection will fail. In that case a retry
dialog will appear like this one below:
If you had typed the correct RNAME this gives you the
opportunity to start the Nirvana realm or interface
needed and click yes to retry the connection without
entering the information again. If however the RNAME
entered was wrong or you do not wish to retry then clicking
no will close the dialog. Finally dont forget that to
make this connection get attempted each time you start
Enterprise manager you need to save
your connection information.
