5. 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

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
