Description

when running tests on the integration server where already a cdmserver instance is running write permission problems are reported regarding the ehcache diskStore, is this a conflict of multiple vm instances using the same disk store location?

2016-12-19 15:38:09,969 WARN [net.sf.ehcache.DiskStorePathManager] - diskStorePath '/home/andreas/.cdm-server-ehcache' is already used by an existing CacheManager either in the same VM or in a different process.
The diskStore path for this CacheManager will be set to /home/andreas/.cdm-server-ehcache/ehcache_auto_created8966675037271472395diskstore.
To avoid this warning consider using the CacheManager factory methods to create a singleton CacheManager or specifying a separate ehcache configuration (ehcache.xml) for each CacheManager instance.

solution: use timestamp prefix for diskStore?

in /cdmlib-remote/src/main/resources/eu/etaxonomy/cdm/remote/ehcache.xml

<diskStore path="java.io.tmpdir/cdm-server-ehcache" />

should become something like

<diskStore path="java.io.tmpdir/cdm-server-ehcache/20120010298321730/" />

could this be achieved by using the ehcache.disk.store.dir property? setting it during app-context startup to a unique subfolder of /tmp/

NOTE: there is a class eu.etaxonomy.cdm.api.cache.CdmCacher providing a static method getDefaultCacheManager()
