Summary


What is Cloudscape?

An embeddable, lightweight, relational SQL database engine for Java.


History

Cloudscape, Inc. founded in 1996 by a team of experts from Informix, Illustra, Oracle and Sybase

Purchased in September of 1999 by Informix Corporation

Acquired by IBM with Informix purchase in July of 2001

Released by IBM as open source (“Derby”) in September of 2004


Cloudscape- Key Features


Cloudscape- Key Features

100% Pure Java Completely portable to any hardware, any OS Only requires JVM (J2SE 1.3 or higher)

Embeddable Can be installed as a JAR file (as part of a Java application) Can be started within an application Installation, startup and shutdown are invisible to user

Fully-functional RDBMS

Adheres to standards JDBC SQLJ ANSI SQL-92


Key Features (continued)

"Zero" Administration No need for DBA at customer site Users may even be unaware that a database engine is present

Lightweight Approx. 2MB “footprint” Can run on many “palm”-size devices (new feature!)

Scales to Moderate Size No defined limits on table sizes Table size limit of 2GB in some environments (OS limit) Existing customer databases of >10 GB working well

Supports Disk Encryption Tested with IBM JCE


Key Features (continued)

Easy for Application Developers to Use To set up, just copy Cloudscape JAR files and set Java

CLASSPATH Database engine starts automatically when application attempts to

connect to it

Cloudscape databases are completely portable To move a Cloudscape database to another machine, just copy it!

(This works even if the machines have different OS or hardware!)

Distributed transaction support (new!) Participates in XA transactions with other database systems


Cloudscape is a Fully-Functional RDBMS Indexes

Views

Triggers and Stored Procedures

Constraints (primary-key, foreign-key, unique, check)

Concurrency Support Transactions (with crash recovery) Savepoints Row-level locking, with escalation JDBC isolation levels (including dirty-read)

Scrollable Cursors (result sets)

Cascading Delete

Internationalization/Localization Support


IBM Products Using Cloudscape

WebSphere (WSAD and WAS) Cloudscape used for sample applications Can handle pooling of Cloudscape connections

Tivoli Monitor and Tivoli Storage Area Network Manager Both use embedded Cloudscape

Lotus LearningSpace Uses embedded Cloudscape

IBM Workplace Client Uses embedded Cloudscape

Many others deployed and under development


Deployment Options: single- or multi-user


Apache Derby Architecture

Two Deployment OptionsEmbedded

• Derby disappears into the application• Zero Admin

Network Server• Familiar client-server architecture• Low Admin

Additional Option for Development Embedded Network Server


Cloudscape Architecture: Embedded

Java Virtual Machine(JVM)

Derby engine

Database(s) on disk

Application

JDBC

• Database only accessible from single JVM

• Java/JDBC only

• No network connectivity

• Any number of concurrent connections

from any number of threads in this JVM

•Typically a single application (but could be multiple)


Cloudscape Architecture: Network Server

Java Virtual Machine(JVM)

Derby engine

Derby NetworkServer

DB2 Universal JDBC Driver(JCC)

CCC (CLI/ODBC)

-Multiple Client applications-Remote or local

PHP / Perl on top of ODBC

Client Applications via

Derby Network Client

Database(s) on disk


Running on Small Devices (J2ME)


J2ME/CDC/Foundation

J2ME – Java 2 Micro Edition

CDC – Connected Device Configuration

Foundation Profile 1.0 Set of java core libraries supported

Sub-set of J2SE 1.3

Set-top boxes, embedded servers, cash registers PDA’s starting to use J2ME/CDC/FP

Not cell-phones, that’s J2ME/CLDC/MIDP

Uses subset of JDBC 3.0 (JSR-169)

Look for the abbreviation: J2ME/CDC/FP


Cloudscape on J2ME

Same Jar file – derby.jar10.1 supports J2SE 1.3, 1.4, J2SE 5.0, J2ME/CDC/FPJ2ME/CDC/FP is new for 10.1

Only Cloudscape embedded supported

Application development expected to be on J2SE

Network Server, Client, JCC not supported in J2ME

On-disk database format remains unchangedCan copy unencrypted databases between J2ME, J2SE and J2EE


How do you tell that it’s J2ME?

Sysinfo will report J2ME info

Development Environments for Cloudscape


Derby Eclipse Plug-In

Integrates with Eclipse Manage network server Run ij Execute sql scripts Run sysinfo Create and run database

applications


Cloudscape Workbench

Eclipse Rich Client Platform (RCP) stand alone only ~25 meg

Browse database Create objects Insert/update/delete Extract/load tables Generate DDL Migrate Derby to DB2


Gluecode SE

Lightweight Java App Server Apache Geronimo

J2EE 1.4

Apache Derby Messaging Services (ActiveMQ) Management Console


Other Development Options

C/C++

PHP Zend core: http://www-306.ibm.com/software/data/info/zendcore/

Perl

Python

Other languages (ODBC through Network Server)



The problem Developers on large projects need a database for unit testing Usual practice: a development database (such as IDS) on a server

However, this has many disadvantages Must pay for database license (IDS or DB2 UDB) on server Requires a DBA to set up and administer the development

database BIGGEST PROBLEM: Whenever one developer “trashes” the

database, work stops for everyone, and the DBA must rush to fix it!


Cloudscape as a Development Database (cont.)

A better solution: A Cloudscape database for each developer Create a “master” database, then copy onto developer workstations If any developer “trashes” it, he/she just re-copies from the master! No DBA required, and other developers are not affected!

Later, when modules are integrated, switch to “enterprise” database (IDS, DB2 UDB, Oracle, etc.)



Java sync client for Cloudscape

Works with DB2Everyplace Sync Server

100% Java

Synchronize Cloudscape clients to any database supported by DB2E Sync Server, including Cloudscape DB2 UDB V7 and V8; also DB2 on zSeries and iSeries IBM Informix (IDS) Oracle MS SQL Server Sybase IBM Cloudscape


DB2 Everyplace Sync Server Architecture


DB2 Everyplace Sync Server- Key Features

Efficient 2-way synchronization Supports most server databases (DB2 UDB, IDS, Lotus Domino,

Oracle, SQL Server, Sybase and Cloudscape) on many platforms Optimized, secure transmission (56-bit or 128-bit encryption)

Centralized administration Data subscription by user or group, with data filtering Customizable conflict resolution (using “user exits”) Automatic distribution of data, files and applications Monitor synchronization progress in real-time Zero administration on mobile device

Scalable Supports WAS Server Groups for high availability and scalability Automatic upgrades of client database software


Derby is Cloudscape


IBM Cloudscape based on Open-source Apache Derby

IBM contributed Cloudscape relational database technology to Apache Software Foundation

Derby Accepted as Apache Incubator Project in August ’04

No “viral” open source licensing issues with either Apache Derby or IBM Cloudscape

No fee required by Apache or IBM
