MATLAB: Errors when i start matlab

bundlearchiveMATLAB

I am getting some error messages when i startup matlab that weren't appearing a few days ago

ERROR: org.apache.felix.framework.cache.BundleArchive: Unable to create archive directory.

ERROR: org.apache.felix.framework.cache.JarRevision: Unable to create revision directory.

is there a way to fix these errors

It appears that you might have a permission problem. The official bug report is here and there is someone reporting it as a permissions problem over here

The later also indicates that it could be a problem with the Java versions, so you might have to reinstall Java

Possibly if you start up MATLAB as root / administrator then that might fix the problem.

Eventually I submit this to the Matlab Support.

Note: I "solved" this by using the open-source and not the proprietary driver.

MATLAB: Change .felix OSGi cache directory

I contacted support and was given a list of variables and properties that are checked in order for a valid place to put this cache along with some suggestions on how to set it up. Here is an excerpt from that response that gives the list: There are a few locations where MATLAB will try to create this cache, in order of precedence (where MATLAB will try the next option if the specified variable is not set or the location which it specifies is not writable by the user who is running MATLAB):

 - Directory specified by environment variable TMPDIR
 - Directory specified by environment variable TMP
 - Directory specified by environment variable TEMP
 - Directory specified by Java property java.io.tmpdir
 - Directory specified by environment variable HOME
 - Directory specified by Java property user.home

Changing the TMPDIR variable to a different path would resolve the issue. However I would not suggest doing that as it might temper with the other processes that use the /tmp to store the temporary files.

What I would suggest is setting this variable 'TMPDIR' only in a given MATLAB session. This can be don by setting this variable in "startup.m" and resetting it back in "finish.m".
