WebSphere Application Server V6.1.x requires Cloudscape to run at a minimal version of v10.1x, which differs radically from previous releases of the database.
Use Cloudscape v10.1.x as a test and development database only.
The new code base
Unlike versions 5.1.60x and earlier, the new Cloudscape is a pure Java database server. The Cloudscape v10.1.x code base, which the open source community calls Derby, is a product of the Apache Software Foundation (ASF) open source relational database project. The new Cloudscape includes Derby without any modification to the underlying source code. Learn more about Derby code at the Apache Derby website: http://db.apache.org/derby/.
Support for two phase-commit transactions over the Network Server framework
Only the Network Server framework provides support for multiple Java virtual machines (JVMs), such as application servers, to access Cloudscape. Earlier versions of Cloudscape cannot conduct two phase-commit transactions over the Network Server framework. However, the new Cloudscape can conduct XA transactions over Network Server; the new Derby Client JDBC driver gives Cloudscape v10.1.x that capability.
New Tools Cloudscape v10.1.x is equipped with the following .bat/sh tools:
For transitioning users: Use ij as an alternative for the old Cloudscape cview tool,
which does not exist in version 10.1.x.trns
When you run ij, surround the dbname by double quotation marks (" ") if it includes the full path name; for example: ij> connect '"c:\temp;create=true"'
This is ' " " ' without spaces.
Continued support
The new Cloudscape package that is bundled with WebSphere Application Server
shares this important feature with earlier packages: It is backed by full
IBM Quality Assurance (QA).
