changeDesignated

public void changeDesignated(String resourceName,
                             String persistenceUnit,

                      throws DbDaoTransactionException

Changes designation to specified resourceName static lock object in conjunction with synchronized keyword ensures that designation changes are done serially within a resource. I.e. static lock ensures that multiple instantiations of DbDAO don't interleave changeDesignated() invocations and potentially produce simultaneous designations. Optimistic locking (the default, versus pessimistic) is sufficient to avoid simultaneous designations from interleaved changeDesignated() invocations from different resources (entities), because it prevents "dirty" and "non-repeatable" reads.

Throws:

DbDaoTransactionException
