Question
We observe IBM Business Automation Workflow created below file in tmp directory:
/tmp/javasharedresources/C290M4F1A64P_webspherev85_1.8_64_bundled_ibmadmin_G43L00
What does it do? Can we delete it? What would happen if we delete it?
Answer
The /tmp/javasharedresources directory is the default location in which to store shared classes caches for any JVM running under any user account - i.e. it has to be accessible for all users. But the cache files stored in this directory are, by default, only read/writeable by their owner.
For non-persistent caches a couple of control files are placed in /tmp/javasharedresources which are world-readable, but their content is not sensitive.
If desired, the shared classes cache folder can be set to a different location with customized permissions, see cacheDir and cacheDirPerm for details.
The files under /tmp/javasharedresources/ folder would be re-generated when server restarts.
You need to following the instruction about how to clear the WebSphere class cache.
