C.3.1.3.36 Re-enabling the REST Administration Interface After Downgrading

If the REST Administration Interface was used before the upgrade attempt, you must re-create the APEX_INSTANCE_ADMIN_USER. If the REST Administration Interface was not used, skip this step.

  1. Change your working directory to apex in the, XX.X release source (where XX.X is the release number you reverted to).
  2. Start SQLcl and connect to the database where Oracle 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. If the no authentication was used, run the following:
    create user apex_instance_admin_user no authentication
  4. If the authentication was used, run the following:
    create user apex_instance_admin_user identified by <random-password> password expire
