Two years after it acquired Digital Equipment's Rdb, Oracle has delivered the first self-engineered version of the database. Rdb Release 7.0 runs under VMS and Unix on Digital's Alpha and VAX platforms and the upgrade focuses particularly on high availability and client/server development facilities.
Oracle claims this is the first Rdb release to take advantage of the 64-bit capabilities in Digital's Alphaserver 4000 and 8000 systems. New features include record caching and vertical partitioning, which improve transaction processing performance without the need to change existing Rdb applications.
High availability is an issue that Rdb users rate highly, claims Oracle, following a string of user surveys. To this end, it has included fault tolerant features such as online maintenance for very large databases. The Hot Standby option allows Rdb7 users to locate a standby system anywhere on a wide area network in the event of a system failure at the main site.
To aid client/server development, Rdb7 supports SQL92 services and ODBC application programming interfaces from client platforms, so that most popular desktop development toolsets can be used.
