The Un-installation Feature

You can use the installation package for this product to remove a Lawson Environment and Environment subproducts.

Note: Before you use the un-installation feature, ensure that you review this section to understand how the feature behaves. The un-installation feature is not completely automated. To completely remove an Environment and all subproducts, you will need to use a combination of Lawson un-installation tools, third party products, and command-line deletions.

Which Components are Removed?

The following list provides general rules about objects that are deleted by the un-installation program.

  • All components delivered by this installation plus any installed Environment subproducts are removed. An Environment subproduct is defined as any product that requires an existing Environment instance to install. The table below provides a list of Environment products and how they are affected by the un-installation program.

    Note: If you want to remove a subproduct without deleting the whole Environment, use the un-installation feature for that subproduct. For example, to remove Lawson Portal but leave the rest of the Environment intact, use the Lawson Portal un-installation feature.

  • GEN and LOGAN tables in the RDBMS are removed, but the table and index spaces in the RDBMS remain intact. You can use them again if you want to re-install.

Which Components are NOT Removed?

The following list provides general information about objects that are not automatically deleted by the un-installation program. These items must be removed after the un-installation is complete.

  • The Lawson directory structure, including GENDIR, LAWDIR, LADBDIR, and subdirectories.

  • The following file types are not removed:

    • Configuration files

    • Log files

    • Compiled programs, for example LOGAN and ERP applications

    • Files created after the original installation was complete: for example, files created by the customer or files created at runtime

  • Environment entries in /etc/lawson.env

  • Components that create their own named instances for installation purposes, which are listed in the table below. These components must be removed separately using the installation package for that product. See the product installation guide for detailed instructions.

  • Application tables and data in the RDBMS are not removed. You must clean these up manually.

  • Lawson programs that are not subproducts of the Environment (such as EPM or SA products) are not removed.
