Press Releases
San Francisco, CA – February
26, 2004 – The Open Group announced the release
of the Distributed Relational Database Architecture (DRDA)
version 3 Technical Standard, which defines specifications
for communications between application environment and relational
database management systems (RDBMS). DRDA version 3 extends
specifications set in version 2, delivers improved platform-independent
SQL functionality and connectivity for JDBC and ODBC drivers,
and provides enhanced security and reliability.
“Our members consider secure seamless database interoperability
across platforms and systems to be critical, and an important
step in achieving their vision of Boundaryless Information
Flow™,” said Allen Brown, President and CEO of
The Open Group. “The new security enhancements in DRDA
V3 will be of particular interest to companies that use DBMS
from multiple vendors and want to set a higher level of trust
for their clients.”
“We are very interested in deploying products that will
support the DRDA V3 standard,” said Bob Perih, First
Vice President, Database Systems, Citigroup. “Tight
security is always a top priority in financial services, and
the addition of data stream encryption fills a key requirement
for us.”
DRDA 3 enhanced security and reliability features include:
- Better diagnostics provided by database servers to application
servers, including the ability to identify where in the
network a request failed
- SSL support for complete data privacy or sensitive data
encryption
- Kerberos authentication support, where the Kerberos principal
for the database server generates an encrypted Kerberos
5 ticket to authenticate the end user associated with the
application server
- Full exploitation of XA
(Distributed Transaction Processing) interface to allow
multiple applications to share resources across multiple
database servers, and allow their work to be coordinated
into global transactions; this support can be used to support
JTA/JTS distributed transactions
- Enables the application server to ask the database server
to return the elapsed time used to process a request, by
requesting it to be monitored.
- Ability to pass the ARM correlator as described in the
Application
Response Measurement API, and bindings for "C",
and Java,
designed to measure the response time and status of transactions
executed by application software
- Application server fail-over to a backup database server
Enhanced functionality also includes new commands to improve
SQL package management, ability to interrupt a long running
SQL request at a database server, more descriptive information
returned for SQL statements executed at a database server,
support for forward and backward scrolling SQL cursors at
a database server, SQL query updates against a database server,
support for long SQL identifiers and long package names, support
for SQL array processing for input and output data objects,
and better control of SQL queries and result sets.
DRDA version 3 is published as a 3-volume set: Volume 1, C043:
Distributed Relational Database Architecture, Volume 2, C044:
Formatted Data Object Content Architecture, and Volume 3,
C045: Distributed Data Management Architecture. It replaces
DRDA version 2 standard (C911, C912, C913), which was published
in December 1999 and which is now deprecated. DRDA version
3 is publicly available at http://www.opengroup.org/publications/catalog/dm.htm.
