Automatically Determining Compatibility of Evolving Services - Becker, Karin; Lopes, Andre; Milojicic, Dejan; Pruyne, Jim; Singhal, Sharad
Keyword(s): SOA, service, backward compatibility, version
Abstract: A major advantage of Service-Oriented Architectures (SOA) is composition and coordination of loosely coupled services. Because the development lifecycles of services and clients are de-coupled, multiple service versions have to be maintained to continue supporting older clients. Typically versions a ...

Hi all,
When I use an editor (vi) that is spawned in a remote server, visually I could see the latency between typing a character/word and being displayed on the terminal. I could see this visually but how do I get a metric on this or how to quantify this?
As expected, when I type in a editor... (6 Replies)

mono-service2
Mono(Mono 1.0) Mono(Mono 1.0)
NAME
mono-service, mono-service2 - Mono ServiceProcess host
SYNOPSIS
mono-service [options] program.exe
DESCRIPTION
The mono-service is a host to run services built with the ServiceProcess assembly.
Use mono-service to run services that use the 1.0 assemblies and use mono-service2 to run services that use the 2.0 assemblies.
Services can be paused by sending the SIGUSR1 signal to the process, and execution can be resumed by sending the SIGUSR2 signal. The ser-
vice can be cleanly shutdown by sending the SIGTERM signal to the process.
Mono programs started with mono-service run with the MONO_DISABLE_SHM variable set. This means that certain Mono features that depend on
it are not available to services.
The following options can be used to control the service:
-d:DIRECTORY
Use this option to specify the working directory for the service. The default is the current directory.
-l:LOCKFILE
Specifies the file to use for locking, the default is a filename constructed in /tmp based on the name of the program that hosts the
service.
-m:MESSAGE
Name to show in the syslog.
-n:NAME
Use this to specify the service to be launched (if the program contains more than one service). The default is to run the first
defined service.
--debug
Use this option to prevent mono-service from redirecting stdin and stdout and prevent the program to be sent to the background.
Equivalent to --no-daemon
--no-daemon
Use this option to prevent mono-service from redirecting stdin and stdout and prevent the program to be sent to the background.
Equivalent to --debug.
CONTROL
You can control the service by sending signals to the process, you can use the following commands:
Pausing service:
kill -USR1 `cat <lock file>`
Resuming service:
kill -USR2 `cat <lock file>`
Stopping the service:
kill `cat <lock file>`
EXAMPLES
Start the MyService.exe assembly, with a lock in /root/service-lock:
mono-service -l:/root/service-lock MyService.exe
DEBUGGING
Messages produced by the service are logged on syslog.
