Persistent servers are just like shared servers, except that
the BOA daemon does not activate them. Instead they have to be started
by means outside of the BOA, e.g. by a system administrator or a shell
script. The code of a persistent server looks exactly like that of a a
shared server. But note that once deactivate_impl() and
shutdown() are called the server will not be restarted
by the BOA daemon.
That means persistent servers do not need a running BOA daemon. Instead
clients can connect directly to the object implementation, giving you better
performance. See section 3.3.3 for an example. However,
there is a reason to have even persistent servers register with the
BOA daemon: you can do a bind() using the address of the BOA daemon,
that is you do not need to know the address of the persistent server. Making
a persistent server register with the BOA daemon is done like this:
some_server -OARemoteAddr <micod-address> -ORBImplRepoAddr <micod-address> \
-OAImplName <impl-name>
where <micod-address> is the address micod is bound
to
. This
is usually the same address you used as an argument to -ORBIIOPAddr
when starting micod. See section 3.3.3 for details
on addresses, sections 4.1.1 and 4.3.1 for details
on command line arguments. <impl-name> is the name of the entry in
the implementation repository the corresponds to the server.
