! <name>cache-between-transactions</name>
! <usage-description>
! The cache-between-transactions element tells the EJB container
whether
! to cache the persistent data of an entity bean across (between)
! transactions.
!
! When a value of 'true' is specified caching between transactions
is
! enabled and long term caching of data is performed. If a value of
! 'false' is specified, (the default) short term caching is done,
which
! means that data is only cached during an individual transaction.
A
! value of 'true' is only allowed if the concurrency-strategy for a
bean
! is either Exclusive, ReadOnly, or Optimistic.
!
! A ReadOnly bean simply ignores the value of the
! cache-between-transactions element since long term caching of
readonly
! data is always performed.
!
! When long term caching is enabled for Exclusive concurrency, the
EJB
! container must have exclusive update access to the underlying
data,
! i.e. the data must not be updated by another application outside
of
! the EJB container. If an Exclusive bean is deployed in a
cluster, long
! term caching is disabled automatically because any node in the
cluster
! may update the data, making long term caching impossible. (Note:
In
! releases prior to WLS 7.0, this feature was controlled using the
! db-is-shared element.)
!
! When long term caching is enabled for Optimistic concurrency, the
EJB
! container reuses cached values from previous transactions, but
ensures
! that updates are transactionally consistent by checking for
optimistic
! conflicts at the end of the transaction. In addition,
notifications
! for updates of optimistic data are broadcast to other cluster
members
! to help avoid optimistic conflicts.
