Extend the TWA Object

Any modifications to the CA CMDB family schema require parallel modifications to the TWA schema. If no custom families or attribute have been defined, the TWA requires no modifications.

To extend the TWA object

1. Customize the user-defined families and attributes using the procedures in Extending CA CMDB in the Administration Guide.
2. Add the new family attributes to the ci_twa_ci schema using Web Screen Painter Schema Designer.

   To add a new attribute to ci_twa_ci schema:

   1. Using Web Screen Painter Schema Designer, open the schema for the ci_twa_ci table.
   2. Add the desired family attribute to the extension table.
   3. Publish the modified ci_twa_ci schema.

   Note: The new attributes must be type STRING and hold the longest possible text value.

3. Add the metadata for the custom family to the TWA as follows:
   1. Using Web Screen Painter, open the cmdb_metadata_site_families.htmpl file.
   2. Add an PDM_INCLUDE for the appropriate cmdb_metadata_extension.htmpl file that was created for the custom family.
