  1. I have the same problem. Please, help. I am running everything on my laptop with hostname MSI. The OS is Windows 10, the database is Oracle 18c (18.4.0.0.0) Express Edition. I installed APEX 20.2 into a pluggable database, under login SYS@pdbname AS SYSDBA. Then, I downloaded ORDS, ran it in install mode, and finally started it in a standalone mode. The URL: http://MSI:8080/ords/apex_admin shows a Web page with the title ORACLE REST Data Services and with 404 error message:

    • The procedure named apex_admin could not be accessed, it may not be declared or the user executing this request may not have been granted execute privilege on the procedure. Check the spelling of the procedure and check that the execute privilege has been granted to the caller

    I checked in the database and – yes- there is no PL/SQL procedure named APEX_ADMIN in any of the following schemas that I have in this pluggable DB: APEX_200200, APEX_INSTANCE_ADMIN_USER, APEX_LISTENER, APEX_PUBLIC_USER, APEX_REST_PUBLIC_USER, ORDS_METADATA, and ORDS_PUBLIC_USER.

  2. worked this time, after executing below.

    SQL> CONN sys@cdb1 AS SYSDBA

DECLARE
  l_passwd VARCHAR2(40);
BEGIN
  l_passwd := DBMS_RANDOM.string('a',10) || DBMS_RANDOM.string('x',10) || '1#';
  -- Remove CONTAINER=ALL for non-CDB environments.
  EXECUTE IMMEDIATE 'ALTER USER anonymous IDENTIFIED BY ' || l_passwd || ' ACCOUNT UNLOCK CONTAINER=ALL';
END;

  3. Hi

    You can’t install two versions of Apex in the same (pluggable) database.

    You wrote:

    I see the user APEX_200100 is already getting created in 4th step (@apexins.sql) itself.

    apexins.sql is the setup for Apex with Apex Builder.

    When I run 5th step (@apxrtins.sql), it fails with same error.

    apxrtins.sql is the run-time only version of Apex.

     

     

     

  4. It is clearly stating that the installation of Oracle Apex 20.1 already exists, but still, you are trying to install it.

    . FAIL – This version of Application Express is already installed.

    . FAIL – Precondition for Phase 1 failed: APEX_200100 already exists

    If you really want it to install a new installation, you must first remove the old one using the following script (must be logged on as SYS):

    @apxremov.sql

  5. Ok I think, there is an issue due to the pluggable database. To install Oracle Apex on Oracle database 12c or later, you need to set the session’s container database (PDB).

    After logging in as SYS user, execute the following command:

    alter session set container = yourPDBname;

    Then run your scripts.

    Also, before running the installation, run the apxremove.sql to remove the existing installation.
