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.If you are running a WebSphere Application Server Network Deployment configuration, you must ensure the correct server or scope is set before completing these steps.
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.
In a Network Deployment configuration, you must ensure the correct server or scope is set for this variable to take effect. Typically the scope is the server on which you are running Cloudscape.
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.
