Subject Running several instances of Felix
Date Wed, 19 Jun 2013 07:42:59 GMT
Hi everyone,

We have developed a simulation software based on OSGi and using Felix.

The execution of the application is done in a script that executes the following command:
java -jar -Dfelix.config.properties=file:./resources/felix/config.properties ./dependencies/thirdparty/felix-4.0.2/felix.jar

We then have two folders containing all the OSGi bundles that are automatically installed
and started by felix when it is launched.

This works very well.

Users have however requested to be able to launch several instances of our software (to run
several simulations in parallel for instance). This however does not work and I think felix
has difficulties dealing with the cache folder when multiple instances are running in parallel

Our Felix config.properties file is in attachement.

Does anyone know how to solve this problem?

Kind regards,

Ben

# Framework config properties.

# To override the packages the framework exports by default from the
# class path, set this variable.
#org.osgi.framework.system.packages=

# To append packages to the default set of exported system packages,
# set this value.
#org.osgi.framework.system.packages.extra=

# The following property makes specified packages from the class path
# available to all bundles. You should avoid using this property.
org.osgi.framework.bootdelegation=sun.awt.*, sun.sun.*, com.sun.org.*, com.sun.*, sun.*, org.w3c.dom.traversal
#sun.*, com.sun.*

# Felix tries to guess when to implicitly boot delegate in certain
# situations to ease integration without outside code. This feature
# is enabled by default, uncomment the following line to disable it.
#felix.bootdelegation.implicit=false

# The following property explicitly specifies the location of the bundle
# cache, which defaults to "felix-cache" in the current working directory.
# If this value is not absolute, then the felix.cache.rootdir controls
# how the absolute location is calculated. (See next property)
#org.osgi.framework.storage=${felix.cache.rootdir}/felix-cache

# The following property is used to convert a relative bundle cache
# location into an absolute one by specifying the root to prepend to
# the relative cache path. The default for this property is the
# current working directory.
felix.cache.rootdir=${user.dir}

# The following property controls whether the bundle cache is flushed
# the first time the framework is initialized. Possible values are
# "none" and "onFirstInit"; the default is "none".
org.osgi.framework.storage.clean=onFirstInit

# The following property determines which actions are performed when
# processing the auto-deploy directory. It is a comma-delimited list of
# the following values: 'install', 'start', 'update', and 'uninstall'.
# An undefined or blank value is equivalent to disabling auto-deploy
# processing.
felix.auto.deploy.action=install,start

# The following property specifies the directory to use as the bundle
# auto-deploy directory; the default is 'bundle' in the working directory.
felix.auto.deploy.dir=./dependencies/main

# The following property is a space-delimited list of bundle URLs
# to install when the framework starts. The ending numerical component
# is the target start level. Any number of these properties may be
# specified for different start levels.
#felix.auto.install.1=

# The following property is a space-delimited list of bundle URLs
# to install and start when the framework starts. The ending numerical

#felix.auto.start.1=

felix.log.level=1

# Sets the initial start level of the framework upon startup.
#org.osgi.framework.startlevel.beginning=1

# Sets the start level of newly installed bundles.
#felix.startlevel.bundle=1

# Felix installs a stream and content handler factories by default,
