The remote process sends a heartbeat over the socket periodically. If
the heartbeat is missing we need to re-establish the socket by waiting
for the remote process to come back up and connect.
I could register a proxy service when there is a connection and
unregister it when the connection is lost. Can you give me a pointer to
how to dynamically register / unregister a service?

I'm afraid Neil's proposal puts the exact same problem in another component.
He is correct that you should NOT call any of the lifecycle methods that DS
calls. On the other hand the original request isn't very well formed.
What is your goal here? Do you want a service "proxying" the remote process to
be registered only when there is a connection to the remote process? How do you
determine whether or not the remote process is available and when its availability
changes?
I don't understand your problem yet, but you might consider having the activate
method start a thread that manages the connection to the remote process, and
registers a service when is establishes the connection and unregisters the
service when the connection fails or ends. The deactivate method can stop this
thread.

No you should not call activate/deactivate yourself, these are intended to be
called by the framework.
Instead, represent the remote process as a service, then bind the service into
your DS component using a mandatory reference.

I have a Service Component that communicates with a remote process via a
socket. The activate methods waits for the remote process to come up and
then establishes communication. If that remote process goes down I need to
go through the same process that the activate method uses to establish
communication.
I haven't been able to find any information on restarting a Service
Component. Can I programatically restart a Service Component, or would it
be better to call deactivate() and activate() on the same Service Component?
Thanks.
