The nautical product library data model includes XML columns as of version 10.1. XML columns use the Oracle Text components, which must be included when configuring a new Oracle database instance. To use them, you must grant privileges to users who will own the XML columns. Execute the following statement as the sys user in SQL*Plus.
grant EXECUTE ON ctxsys.ctx_ddl to PRODLIB;
If XML columns are written in languages other than English, additional configuration may be necessary.
