By default, the bundle cache is stored in InstallDir/data/cache.

To specify an alternative location, use the org.osgi.framework.storage property in config.properties.

If you use a relative path, the cache location is added to the root of the Fuse ESB installation directory.

You can configure Fuse ESB to flush the bundle cache every time the runtime starts by setting the org.osgi.framework.storage.clean property to onFirstInit in config.properties. This property is set to none by default.

The generated-bundle cache is where the container caches bundles it creates to support JARs that are not supplied as OSGi bundles.

You can configure the location of this cache by changing the felix.fileinstall.tmpdir property in the org.apache.felix.fileinstall-deploy.cfg file.

The felix.cache.bufsize property controls the size of the buffer used to copy bundles into the bundle cache. Its default value is 4096 bytes.

You can adjust this property by editing its value in the config.properties configuration file. The value is specified in bytes.
