Reading in variables (system names) from OVO into a script.

[Jeff Cline]

I am trying to write a script that will be launched from OVO (Application Back) which will read in the selected nodes and run the script against each node (system). My questions is how do I get the variables assigned because the number of nodes can change each time you run the script. OVO will launch the script and then send the selected nodes name to the script but I do not know how to read in the names. Any help would be appreciated.
Thanks!

Hi,

In HP-UX you can use hostname command. This shows you the name of the machine.

Sorry, don't know the acronym OVO (blush), but assigning the node name to a variable is easy.

e.g.

POSIX shell (i.e. standard HP-UX sh)

node=$(/usr/bin/uname -n)

or

node=$(/usr/bin/hostname)

in other shell you may have to use backticks instead of $(...)

node=`/usr/bin/uname -n`


If you like Perl you can either use

use POSIX;

my ($node) = (POSIX::uname)[1];


or

use Sys::Hostname;

my $node = hostname;

Hi Jeff,

in Opc/ITO/VPO/OVO the "Applications" in your "Application Bank" get the names of the selected "Managed Nodes" passed over in the variable "$OPC_NODES".
So within your script you do something like:

for node in $OPC_NODES
do echo "going for $node:"
# call your command here
echo "done with $node"
done

Find the details in the OVO "Application Integration Guide", chapter 3 (="Integrating External Applications into the VPO GUI")...

HTH,
