IBM Cloudscape footprint

• Engine jar file is around 2Mb– Optional Jar files

• Network server ~150k• Tools ~200k

• Runtime memory use– Dependent on application, data caching etc.– Can run when Java heap memory restricted to 4Mb– Have run in machines with only 16Mb physical memory

12



IBM Cloudscape Engine

• Database code written using the Java programming language

• Write Once Run Anywhere– Requires a J2SE 1.3 or 1.4 virtual machine– Any hardware, any operating system

• Single binary does run everywhere– Linux, Windows, MacOs, AIX, Solaris, Z/OS, AS400, OS/390, …

• Database on-disk format is platform independent too!

BasicƒConflicts between users changes and between users and source

changes are resolved by the SyncServer during replication cycleƒConflicts are at the row level

RulesƒSource changes take priority over users changesƒUsers changes are prioritized by the age of the base level of data

available to each user, newer base data = higher priorityResultsƒRejected Record is marked in the staging table with a reject codeƒA message will be send to the client in the next sync cycle

–DSYD028I A synchronization element for database 'db', table 'schema'.'table', primary key 'pkvalue', from device 'devtype_devid' was rejected due to 'reason'.

InfluenceƒCustom Logic allows to manipulate after each step

Retail/Easy of Use: Penn StatePenn State Center for Advanced Information Technology

Used DB2 Everyplace in second year college class - students created a 'store' that can be accessed from a Palm device to order or check order status

Use DB2 Everyplace on Palm OS; Sync Server on NT

"We were amazed that DB2 Everyplace was a full function database, yet had a small footprint and ran on an handheld device...And the Mobile Appplication Builder was fantastic - led students through a point and click programming process and automatically created the C code for the Palm..."
