Removing APEX from the Database

Start SQLcl and connect to the database where Oracle APEX is installed as SYS specifying the SYSDBA role and execute the SQL> @apxremov.sql command.

This section describes how to remove the APEX schema, synonyms, and users from the database without deleting the database.

Note: Do NOT follow these steps if you have upgraded your database from a prior release, and still want to use the prior release of APEX. For information about reverting to a prior release, see Reverting to a Previous Release. If you are not sure whether you have completed a new installation or an upgrade installation, review Cleaning Up After a Failed Installation to verify if a previous release of APEX exists in the database.

To remove APEX from the database:

1. Change your working directory to the apex directory where you unzipped the APEX software.

2. Start SQLcl and connect to the database where APEX is installed as SYS specifying the SYSDBA role:

   • On Windows:

     <SYSTEM_DRIVE>:\ sql /nolog
     SQL> CONNECT SYS as SYSDBA
     Enter password: <SYS_password>

   • On UNIX and Linux:

     $ sql /nolog
     SQL> CONNECT SYS as SYSDBA
     Enter password: <SYS_password>

3. Execute the following command:

   SQL> @apxremov.sql

4. After successfully removing APEX using apxremov.sql, you must exit your current SQLcl session and reconnect before attempting another install using apexins.sql.
