    End of change
DB2 Change Management Expert has the following software requirements on the client platform:
  • Connection to a locally installed DB2 database or connection to a DB2 UDB Administration Client (DAS)
  • A Web browser (to view demonstrations of the product in the online documentation)
  • Start of changeIBM Java Runtime Environment (JRE) Version 1.5.0, which is included with DB2 Change Management ExpertEnd of change
  • Start of changeIBM Installation Manager Version 1.0, which is included with DB2 Change Management Expert

    End of change
Start of changeIn addition, if DB2 Change Management Expert V1.1 is currently installed, ensure that it is uninstalled before you install V1.1.1.End of change

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.

To run DB2 Change Management Expert, you must also have connectivity to the DB2 UDB Administration Client (DAS) that is running on the same machine as the database. The DAS connectivity libraries can be provided by either of the following ways:
  • A local DB2 instance
  • The DB2 UDB Administration Client

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.

For example, to install the DAS client on a Linux system, complete the following steps:
  1. Install the DAS Client.
  2. Create a DB2 instance.
  3. Source db2profile in $INST_HOME/sqllib/ before you start DB2 Change Management Expert. (For example, add it to your .bashrc.)
