IBM Software Group | DB2 Information Management Software Outline History Key Features Deployment Options: single- or multi-user Running on Small Devices (J2ME) Development environments for Cloudscape Cloudscape as a Development Database Synchronization with Enterprise Databases Derby is Cloudscape Summary
3
IBM Software Group | DB2 Information Management Software What is Cloudscape? An embeddable, lightweight, relational SQL database engine for Java.
4
IBM Software Group | DB2 Information Management Software 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

IBM Software Group | DB2 Information Management Software Cloudscape- Key Features
6
IBM Software Group | DB2 Information Management Software 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
7
IBM Software Group | DB2 Information Management Software 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
8
IBM Software Group | DB2 Information Management Software 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
9
IBM Software Group | DB2 Information Management Software 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
10
IBM Software Group | DB2 Information Management Software 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
11
IBM Software Group | DB2 Information Management Software Deployment Options: single- or multi-user
12
IBM Software Group | DB2 Information Management Software Apache Derby Architecture Two Deployment Options Embedded Derby disappears into the application Zero Admin Network Server Familiar client-server architecture Low Admin Additional Option for Development Embedded Network Server
13
IBM Software Group | DB2 Information Management Software 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)
14
IBM Software Group | DB2 Information Management Software Cloudscape Architecture: Network Server Java Virtual Machine (JVM) Derby engine Derby Network Server 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
15
IBM Software Group | DB2 Information Management Software Running on Small Devices (J2ME)
16
IBM Software Group | DB2 Information Management Software 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
17
IBM Software Group | DB2 Information Management Software Cloudscape on J2ME Same Jar file – derby.jar 10.1 supports J2SE 1.3, 1.4, J2SE 5.0, J2ME/CDC/FP J2ME/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 unchanged Can copy unencrypted databases between J2ME, J2SE and J2EE
18
IBM Software Group | DB2 Information Management Software How do you tell that it’s J2ME? Sysinfo will report J2ME info ------------------ Java Information ------------------ Java Version: J2ME Foundation Specification v1.0 Java Vendor: IBM Corporation Java home: c:\_work\p4\djdt1\wctme5.7\ive Java classpath: c:/_work/svn_clean/trunk/classes;c:/_work/svn_clean/trunk/tools/java/jakarta-oro- 2.0.8.jar OS name: Windows XP OS architecture: x86 OS version: 5.1 build 2600 Service Pack 1 Java user name: djd Java user home: C:\Documents and Settings\Administrator Java user dir: C:\_work\svn_clean\trunk\systest\out java.specification.name: J2ME Foundation Specification java.specification.version: 1.0 --------- Derby Information -------- JRE - JDBC: J2ME - JDBC for CDC/FP 1.0 [C:\_work\svn_clean\trunk\classes] 10.2.0.0 alpha - (220112M) ------------------------------------------------------ ----------------- Locale Information ----------------- …

24
IBM Software Group | DB2 Information Management Software Cloudscape as a Development Database
25
IBM Software Group | DB2 Information Management Software Cloudscape as a Development Database 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!
26
IBM Software Group | DB2 Information Management Software 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.)
27
IBM Software Group | DB2 Information Management Software Synchronization with Enterprise Databases
28
IBM Software Group | DB2 Information Management Software Synchronization with Enterprise Databases 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
