Hi,

We are using second-level read/write caching to accelerate access to an
often-accessed db object. In hbm file:

<cache usage="read-write"/>

The cache provider is Hibernate's default (EHCache).

We attempt to access this db object from two different
applications running on the same Solaris9 machine, both
accessing it via a second-level cache.

The first application loads fine.

The second application fails to load with the following error:


mypackage.MyDBObjectCache: Could not create disk store
java.io.FileNotFoundException: /var/tmp/mypackage/MyDBObject.data (Permission denied)


our best bet is that upon loading of a second-level-cache marked entity,
Hibernate creats/locks a dedicated file in /var/tmp/. Works fine the
first time. Cannot work afterwards.

is there any way in which we can direct each of our applications
to create the cache data file in a different directory/using a different
name, thus solving the problem.

If not - is there any other solution/workaround?

Thank you,
