System requirements

The minimum system requirements and operating system requirements for the DB2® (Windows/UNIX) Adapter are detailed in system requirements. See also the release notes. The following tasks are also required:

Verify that you have installed the DB2 client software.
Verify that you have configured the DB2 data source or sources. For information about configuring the DB2 data source or sources, see the DB2 documentation.
Verify that the DB2 environment variables are defined. For information about defining the DB2 environment variables, see your DB2 documentation.
Set the shared library path environment variable for UNIX.
After installing the adapters on a UNIX platform and running the environment variable setup program (setup), add the installation directory to your shared library path environment variable if it is not already there. The following instructions assume your installation directory is defined in the environment variable DTX_HOME_DIR.

Note: After you have initially run the setup program, if you make changes to your path and/or library path at a later date, you need to re-run this program.

Note: These instructions assume that your UNIX environment is the Korn (ksh) shell and that the DB2_HOME environment variable points to the DB2 installation directory.
