70.08 	SPARCcluster 1000 PDB & SPARCcluster 2000 PDB

	Sun Microsystems Computer Company (SMCC) unveiled a new
	line of database clustered servers that provide a highly
	scalable, highly available platform for mission-critical
	database applications.  The SPARCcluster(TM) 1000 PDB(TM) and
	the SPARCcluster(TM) 2000 PDB(TM) servers address key customer
	requirements, including access to shared databases, ensured
	data integrity despite failures and fully automated failure
	detection and recovery mechanisms.  Future scalability of up to
	eight nodes ensures long-term protection of customer
	investments.  The first application to be supported will be
	Oracle(R) Parallel Server software.

		NEW SUN PARALLEL DATABASE SERVERS 
	  DELIVER LEADING PERFORMANCE AND AVAILABILITY 
		FOR MISSION-CRITICAL APPLICATIONS

The SPARCcluster PDB servers offer three unique advantages over
competing database cluster solutions.  The servers deliver better
performance scalability by using the industry's first multithreaded
lock manager to speed shared access to disk storage through
multiprocessing.  The servers also use the SPARCstorage(TM)Array disk
subsystem to deliver both lower mass storage costs and faster disk I/O
performance.  In addition, SPARCcluster PDB servers provide the most
comprehensive suite of on-line cluster management software for simpler
centralized control of cluster resources.

No single point of failure  hardware, software or network can bring the
cluster down.  The SPARCcluster PDB servers feature redundant data
paths between all nodes to all disk subsystems and to all external
networks to support high availability.  SMCC's fault management
software detects all failures and manages the recovery process without
operator intervention in a manner that preserves database integrity.
Failed components in the cluster can be replaced on line, without
impacting database availability.

A SPARCcluster PDB server includes at least two systems (a
SPARCserver(TM) 1000E or a SPARCcenter(TM) 2000E), two or more
SPARCstorage Array highly available disk subsystems with redundant
fibre channel host connections, a cluster management console,
SPARCcluster PDB software and SPARCcluster support services package.


Oracle Parallel Server

The first parallel database product available on the SPARCcluster PDB
server is the Oracle Parallel Server from Oracle Corporation.  Built on
a shared disk architecture, the Oracle product works in conjunction
with SMCC's lock manager and provides shared concurrent access to disks
across multiple nodes. With Oracle Parallel Server, customers can
access a single image of the database, supporting both on-line
transaction processing and decision support applications. The
SPARCcluster PDB servers will support future parallel database products
as they become available from companies such as Informix and Sybase.

The two-node configurations of the SPARCcluster 1000 PDB and
SPARCcluster 2000 PDB servers will be available in the first quarter of
1995. Entry-level SPARCcluster 1000 PDB servers start at $387,025 for a
fully functional cluster, while entry-level SPARCcluster 2000 PDB
servers start at $693,175.

Sun Microsystems Computer Company (SMCC), the world's top supplier of
open network computing solutions, is a division of Sun Microsystems,
Inc.  Built on Sun's legacy of "The Network is the Computer(TM),"
SMCC's SPARC(R)/Solaris(R) workstation and server family leads the
UNIX(R) market.  The company has its headquarters in Mountain View,
Calif.
