<p>An application must use distributed transactions whenever it wants transactional semantics either
|
|
|
|
|
|
across operations in multiple Berkeley DB environments (even if they are on the same machine)
|
|
|
|
|
|
or across operations in Berkeley DB and some other database systems (for example, Oracle server).
|
|
|
|
|
|
Berkeley DB provides support for distributed transactions using a two-phase
|
|
|
|
|
|
commit protocol. In order to use the two-phase commit feature of Berkeley DB, an application
|
|
|
|
|
|
must either implement its own global transaction manager or use an
|
|
|
|
|
|
XA-compliant transaction manager such as Oracle Tuxedo (as Berkeley DB can act as an XA-compliant
|
|
|
|
|
|
resource manager).
|
|
|
|
|
|
</p>
|
|
|
|
|
|
<p>This chapter explains Berkeley DB's XA-compliant resource manager, which can be used in any X/Open
|
|
|
|
|
|
distributed transaction processing system, and explains how to configure
|
|
|
|
|
|
Oracle Tuxedo to use the Berkeley DB resource manager.
