Version 5.1.6 (plus any subsequent fix packs for this version) is the minimum level of Cloudscape that is required for WebSphere Application Server V6.0 - V6.0.2.
Why and when to perform this task
After installing Cloudscape Version 5.1.60x, you must complete the following steps before you can access the database.Steps for this task
You must complete a backup in case you have to access the previous version of Cloudscape. After you migrate a database, you cannot access your old database unless you perform a backup.
The data source is located in the WebSphere Application Server administrative console under the JDBC providers.
Note: Ensure you migrate defaultDB, which is located in the WAS_HOME/bin/DefaultDB directory.
Use the WebSphere Application Server environment variable ${CLOUDSCAPE_JDBC_DRIVER_PATH}\db2j.jar to point to the new version of Cloudscape.
The CLOUDSCAPE_JDBC_DRIVER_PATH environment variable is defined in WebSphere Application Server with a value of WAS_HOME/cloudscape/lib.
The data source class name com.ibm.db2j.jdbc.db2jConnectionPoolDataSource could not be found.
This is because the Cloudscape JAR file has moved to from its location in version 5.x to a new location in version 5.1x.
