Hi everyone,

I'm using Infinispan inside Jboss AS 7.1.1.Final as Hibernate 2LC and I'm wondering about the meaning of the <transaction> configuration, in particular about the mode attribute, beacuse I read from the doc (https://docs.jboss.org/author/display/ISPN51/Infinispan+transactions) that it should only be TRANSACTIONAL or NON_TRANSACTIONAL but in the schema (jboss-as-infinispan_1_2.xsd) the possible values are NONE, NON_XA, NON_DURABLE_XA and FULL_XA.

Which is the difference between those values?

Why in the default configuration for 2LC (see below), the entity cache is NON_XA and the others (timestamps and query) are NONE? Is it not better (and safe) to enable transactions for every cache?

As note: I'm working in a cluster environment.

Thanks!
