Top Forums Programming Is it possible to call remote function in another daemon? Post 302520047 by Loic Domaigne on Thursday 5th of May 2011 04:29:45 PM

RPC is one possibility.

Perhaps for your case, a simple IPC between your two deamons could do it. In function s, daemon A requests deamon B to execute the function k by sending a message with the needed argument. Daemon B receives the message, executes function k and sends the returned value(s) back to daemon A. And this point, A can then resume.

Are the two daemons located on the same machine? If so, is there some plan to run them possibly on separate machines?

Cheers, Loïc

NAME
dscfglockd - Availability Suite Services lock daemon SYNOPSIS
/usr/lib/dscfglockd [-e program | -f file] DESCRIPTION
The dscfglockd daemon coordinates StorageTek configuration database lock requests between nodes within a cluster. OPTIONS
The dscfglockd supports the following options: -e program Executes the script and arguments in program. The executable and any arguments it needs must be supplied with suitable quoting as a single argument to this option. This argument is processed by sh(1). -f file Reads the list of names for peer hosts from file. If no arguments are specified, dscfglockd acts as a local lock daemon, but coordinates lock requests with any other daemons that might con- tact the local host as part of their own configuration process. EXIT STATUS
0 Daemon started successfully. >0 Daemon failed to start. FILES
/lib/svc/method/svc-scm Shell script for starting and stopping dscfglockd. ATTRIBUTES
