Forward Directions Rdb



Oracle Corporation is pleased to announce the production release
of version 7.2 of the Oracle Rdb product family. All product
family components are available for download from MetaLink

Now you can have the rock-solid
availability, performance, disaster tolerance, security, and
scalability for which Oracle Rdb is well known on your choice of
Itanium-based or AlphaServer hardware. Nearly all Oracle
Rdb-based applications running on OpenVMS Alpha systems
today need only to be recompiled, linked and tested to run on
Itanium-based servers.

Oracle Rdb release 7.2 is supported on the full range of
OpenVMS certified Itanium-based server configurations
from a single-processor rx1620 to a 16-processor Superdome.
You can deploy on standalone or clustered Itanium-based
servers or add Itanium-based database servers to your existing
OpenVMS cluster of AlphaServer systems.

Oracle Rdb release 7.2 allows direct database access from
multiple nodes in mixed-architecture clusters. Simultaneous
access to the same database from AlphaServer and Itanium-based
server systems within a cluster allows you to port your existing
applications on your own schedule rather than forcing an
“all-or-nothing” migration. These options give you maximum
protection for production environments and permit you to migrate
to lower cost commodity hardware when it makes sense for your

In addition to OpenVMS Itanium support, Oracle Rdb release 7.2
provides a number of new features and performance
enhancements, including:

* Increased maximum number of database global buffers to
reduce the I/O requirement of your workload
* Increased maximum database page and buffer size limits to
retrieve and store more information with a single I/O
* Additional statistics screens and larger counter sizes to make
monitoring your database even easier
* Streamlined internal instruction sequences for more efficient
CPU use
* Improved caching of database AIP entry information for
reduced I/O
* Index node pre-fetch performance optimizations to reduce
I/O stall time
* Transaction rollback performance optimizations to reduce
rollback time
* Encrypted database and after-image journal backups for
protection of confidential data
* Query Optimizer enhancements for more efficient query
execution strategies

With this release, all the components and features of Oracle
Rdb are available for production use on both AlphaServer and
Itanium-based server platforms. These components and
features include:

* SQL interactive and dynamic interfaces
* SQL module language and precompilers
* RDO, RDBPRE and RDML precompilers
* Local and global buffering and row caches
* Data protection and transaction integrity using before-image
and after-image journaling
* Two-phase commit transactions supporting transactions that
span multiple databases
* Remote database access via TCP/IP and DECnet
* Data replication using Oracle Rdb Hot Standby, Oracle Rdb
LogMiner and Replication Option for Rdb
* All Oracle RMU management tools for backing up, verifying,
restoring and monitoring your database
* Oracle Trace for Rdb
* SQL/Services including support for Oracle Call Interface (OCI),
and ODBC
* Oracle Rdb JDBC Drivers

Also, Oracle Rdb releases for AlphaServer systems continue to
be available in two options: a generic kit that runs on any
AlphaServer processor, and a platform-targeted performance
kit that runs on AlphaServer EV56 and later processors.

Oracle Rdb release 7.2 requires OpenVMS Alpha version 8.2 or
later or HP Open Industry Standard 64 for Integrity Servers
version 8.2-1 or later.

The Oracle Rdb product family includes Oracle Rdb Enterprise
Edition, Oracle CODASYL DBMS, Oracle CDD/Repository,
Oracle SQL/Services, OCI Services for Oracle Rdb, Oracle Trace
for Rdb, Replication Option for Rdb, Oracle Rdb ODBC Driver,
and Oracle Rdb JDBC Drivers.
