[Pacemaker] how to run a remote script

[gilberto migliavacca]

Hi Dejan

unfortunately I cannot find a solution about my problem
in the docs.
My concern is about the steps I have to take, maybe it's
not completly clear to me the entore process, sorry but this
is the first time for me;
could you please confirm the following procedure? thanks in advance

1) I have a 1 machine as cluster manager ("machine A")
I have 2 Apache-Tomcat web container on the 2 nodes
("machine B" and "machine C");

2) all the cluster management tools are installed on
the 3 machines

3) I'd like to start/stop tomcat from the "machine A" so
that I open the "crm" command line on "machine A"

4) I create and edit the configuration "my-conf" with
the following instructions:

4.1) primitive res.ocf.tomct ocf:heartbeat:tomcat ...

4.2) primitive res.ip.tomcat ocf:heartbeat:IPaddr2 ...

4.3) Have I to set the colocation in the configuration?

5)?? this is my problem ... which command I have to run
from the "machine A" in order to start/stop the tomcat service
on the
