DB2 HPU must be installed to set and use HPU as the DB2 Change Management Expert Data Unload Provider preference. For more information, see the unload provider options in the Data preservation topic.
The DB2 Change Management Expert installation program requires IBM Installation Manager. The installation program prompts you to install IBM Installation Manager if it is not already installed.
You must ensure that the DB2 libraries are in the PATH environment variable (Windows) or in the LD_LIBRARY_PATH environment variable (UNIX®).
To run DB2 Change Management Expert, you must use the IBM Java™ Database Connectivity (JDBC) Type 4 driver. The JDBC Type 4 driver is included in DB2 Change Management Expert. You can select a different JDBC driver if necessary.
On Linux, if the class location of your JDBC driver (db2jcc.jar and license) is not automatically populated, check your environment. The DB2INSTANCE environment variable should be set to the local DB2 instance name, for example, export DB2INSTANCE=db2inst1 (this is case sensitive). Otherwise, you can specify the location manually.
In either case, make sure the bin directory is in the path before you start DB2 Change Management Expert. (In Linux, this is handled by sourcing $INST_HOME/sqllib/db2profile.) The DB2 UDB Administration Client is available from developerWorks® at http://www.ibm.com/developerworks.
