C.3.1.4 Removing the APEX Release Schema

After you revert to the prior release, remove the Oracle APEX schema.

• Removing the APEX Release 24.1 Schema from a Non-CDB
  Start SQLcl and connect to the database and execute DROP USER APEX_240100 CASCADE; command.
• Removing the APEX Release 24.1 Schema from a CDB
  Create text files, start SQLcl and connect to the database execute @remove_apx241_usr.sql.

C.3.1.4.1 Removing the APEX Release 24.1 Schema from a Non-CDB

Start SQLcl and connect to the database and execute DROP USER APEX_240100 CASCADE; command.

To remove the release 24.1 schema from a non-CDB:

1. 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

2. Execute the following command:

   DROP USER APEX_240100 CASCADE;

   Once you have removed the APEX 24.1 schema, you can now attempt the upgrade again.

C.3.1.4.2 Removing the APEX Release 24.1 Schema from a CDB

Create text files, start SQLcl and connect to the database execute @remove_apx241_usr.sql.

To remove the release 24.1 schema from a CDB:

1. Create a new text file named remove_apx241_usr1.sql with the following contents:

   alter session set current_schema = SYS;
   drop user APEX_240100 cascade;

2. Create a second new text file named remove_apx241_usr.sql with the following contents:

   set define '^'
   whenever sqlerror exit
   column :xe_home new_value OH_HOME NOPRINT
   variable xe_home varchar2(255)
    
   set serverout on
   begin
   -- get oracle_home
       sys.dbms_system.get_env('ORACLE_HOME',:xe_home);
       if length(:xe_home) = 0 then
           sys.dbms_output.put_line(lpad('-',80,'-'));
           raise_application_error (
               -20001,
               'Oracle Home environment variable not set' );
       end if;
   end;
   /
   whenever sqlerror continue
    
   set termout off
   select :xe_home from sys.dual;
   set termout on
   host ^OH_HOME/perl/bin/perl -I ^OH_HOME/rdbms/admin ^OH_HOME/rdbms/admin/catcon.pl -b
         remove_apx241_usr remove_apx241_usr.sql

3. 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

4. Execute the following command:

   @remove_apx241_usr.sql

   Once you have removed the APEX 24.1 schema, you can now attempt the upgrade again.
