Re: [eclipselink-users] Sharing of L1 Cache in case of transaction-type=

[Tom Ware <tom.ware@xxxxxxxxxx>]

The transaction type you use does not impact EclipseLink caching.  EntityManager 
will always use their own L1 cache.

There are a number of settings that allow you to set up the L2 cache.  The 
persistence unit property "eclipselink.cache.shared.default" controls whether 
the L2 cache is shared by default.  (by default it is shared, set that property 
to false to avoid sharing)
