The directory context for Oracle SQL scripts is install-dir\DirXMLUtilities\jdbc\sql\oracle\install.
From an Oracle client, such as SQL Plus, log in as the SYSTEM user.
By default, the password for SYSTEM is MANAGER. If you execute scripts as a user other than SYSTEM with password MANAGER, change all references to SYSTEM in the scripts prior to execution.
Execute the installation script 1_install.sql.
For example: SQL> @c:\1_install.sql
