stresscmd.jar

Description

(Remark: the time is really relevant for heavy service invocation since each call includes the dynamic invocation overhead !)
the stress command stops invocations on the service when this service is unregistered
For more details on how to use this bundle, refer to the /doc/readme.html file embedded in the bundle jarfile.

    Run the demo
    To run the demo of this bundle, enter the following commands in the OSCAR shell

    -> cd http://www-adele.imag.fr/~donsez/dev/osgi/
-> start helloservice11/helloservice11.jar
-> start helloservice10/helloservice10.jar
-> services
-> start stresscmd/stresscmd.jar
-> stress 1000000 (objectClass=fr.imag.adele.bundle.hello.HelloService) sayHello Didier
-> stress -csv 1000000 (objectClass=fr.imag.adele.bundle.hello.HelloService) sayHello Didier
-> stress 1000000 (objectClass=fr.imag.adele.bundle.hello.LocaleService) getLanguage
-> stress 1000000 (objectClass=fr.imag.adele.bundle.hello.LocaleService) setLanguage
-> stress 1000000 (objectClass=fr.imag.adele.bundle.hello.LocaleService) setLanguage fr
...
-> invoke (objectClass=fr.imag.adele.bundle.hello.LocaleService) getLanguage
-> invoke (objectClass=fr.imag.adele.bundle.hello.LocaleService) setLanguage fr
    The output is:
    -> services 27

    Typical Usages

  • stress: for benchmarking services on the gateway
  • invoke: for configuring services through setters/getters (JavaBean,MBean,...)

    • Tested gateways
