1. If necessary, make sure that the login for the installation owner sets LD_LIBRARY_PATH or the platform equivalent.

2. Make sure that the login for the user does not use ingprenv1, or install your ingprenv1 substitute, as described in ingprenv Replaces ingprenv1 (see page ingprenv Replaces ingprenv1).

3. Check all your database owner (DBA) logins to ensure that they are properly set up for Ingres, with LD_LIBRARY_PATH or equivalent, and no use of ingprenv1.

4. Define LD_LIBRARY_PATH or equivalent for the installation owner user session that you will use to install and upgrade Ingres.

5. If you are doing a clean-install upgrade on a different machine, make sure that your login fixes are applied to the new machine, not to the old one.
