Installing APEX into Different PDBs

5.3 Installing APEX into Different PDBs

You can install different versions of Oracle APEX into different PDBs.

If APEX is not installed in the container database, you can install a local APEX within each PDB as required. When APEX is installed locally there are no APEX metadata linked objects and all packages, views, and tables are created within the APEX_240100 schema, within each PDB where APEX is installed.

5.3.1 Uninstalling APEX from a CDB

Learn how to uninstall Oracle APEX from a CDB.

To uninstall APEX from a CDB:

Note:

Installing or removing APEX from a CDB requires a local connection to the database.

This section describes removing APEX from a CDB.

Change to the apex directory in the location where you unzipped the distribution.

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

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

Run apxremov.sql.
For example:
```
@apxremov.sql
```
Note:
If you run apexremov.sql after PDBs have been added to the CDB, then APEX uninstalls from all of the PDBs, as well as CDB$ROOT and PDB$SEED. Any applications defined in any of the PDBs will be removed.

5.3.2 Installing APEX Locally in a PDB

Learn how to install Oracle APEX locally in a PDB.

Once you have removed APEX from the container database by following the instructions in Uninstalling APEX from a CDB, you can install APEX locally in a PDB.

To install APEX locally in a PDB:

Change the apex directory in the location where you unzipped the distribution.

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

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

Set the container to the PDB you want to install APEX locally:
```
ALTER SESSION SET CONTAINER = <PDB_name>;
```
Select the appropriate installation option.
Full development environment provides complete access to the App Builder environment to develop applications. A Runtime environment enables users to run applications that cannot be modified.

Available installation options include:
- Full development environment - Run apexins.sql passing the following four arguments in the order shown:
```
@apexins.sql tablespace_apex tablespace_files tablespace_temp images
```
  Where:
  - tablespace_apex is the name of the tablespace for the APEX application user.
  - tablespace_files is the name of the tablespace for the APEX files user.
  - tablespace_temp is the name of the temporary tablespace or tablespace group.
  - images is the virtual directory for APEX images. To support future APEX upgrades, define the virtual image directory as /i/.
  For example:
```
@apexins.sql SYSAUX SYSAUX TEMP /i/
```
- Runtime environment - Run apxrtins.sql passing the following four arguments in the order shown:
```
@apxrtins.sql tablespace_apex tablespace_files tablespace_temp images
```
  Where:
  - tablespace_apex is the name of the tablespace for the APEX application user.
  - tablespace_files is the name of the tablespace for the APEX files user.
  - tablespace_temp is the name of the temporary tablespace or tablespace group.
  - images is the virtual directory for APEX images. To support future APEX upgrades, define the virtual image directory as /i/.
  For example:
```
@apxrtins.sql SYSAUX SYSAUX TEMP /i/
```
Complete the appropriate steps in Installing and Configuring APEX and Oracle REST Data Services.

When APEX installs, it creates the following database accounts:

APEX_240100 - This account owns the APEX schema and metadata.
FLOWS_FILES - This account owns the APEX uploaded files.
APEX_PUBLIC_USER - This minimally privileged account is used for APEX configuration with Oracle REST Data Services or Oracle HTTP Server and mod_plsql.
APEX_PUBLIC_ROUTER - This minimally privileged account used for an ORDS REST module to resolve friendly URLs.

If you configured RESTful Web services, then these additional accounts are created:

APEX_REST_PUBLIC_USER - The account used when invoking RESTful Services definitions stored in APEX.
APEX_LISTENER - The account used to query RESTful Services definitions stored in APEX.

5.3.3 Installing APEX into a CDB

To install Oracle APEX into a CDB:

Note:

Installing or removing APEX from a CDB requires a local connection to the database.

Change your working directory to the apex directory in the location where you unzipped the distribution.

Start SQLcl and connect to CDB$ROOT of the database where APEX is installed as SYS specifying the SYSDBA role. For example:

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

Select the appropriate installation option.
Full development environment provides complete access to the App Builder environment to develop applications. A Runtime environment enables users to run applications that cannot be modified.

Available installation options include:
- Full development environment. Run apexins.sql passing the following four arguments in the order shown:
```
@apexins.sql tablespace_apex tablespace_files tablespace_temp images
```
  Where:
  - tablespace_apex is the name of the tablespace for the APEX application user.
  - tablespace_files is the name of the tablespace for the APEX files user.
  - tablespace_temp is the name of the temporary tablespace or tablespace group.
  - images is the virtual directory for APEX images. To support future APEX upgrades, define the virtual image directory as /i/.
  Example:
```
@apexins.sql SYSAUX SYSAUX TEMP /i/
```
- Runtime environment. Run apxrtins.sql passing the following arguments in the order shown:
```
@apxrtins.sql tablespace_apex tablespace_files tablespace_temp images
```
  Where:
  - tablespace_apex is the name of the tablespace for the APEX application user.
  - tablespace_files is the name of the tablespace for the APEX files user.
  - tablespace_temp is the name of the temporary tablespace or tablespace group.
  - images is the virtual directory for APEX images. To support future APEX upgrades, define the virtual image directory as /i/.
  Example:
```
@apxrtins.sql SYSAUX SYSAUX TEMP /i/

When APEX installs, it creates the following database accounts:

APEX_240100 - This account owns the APEX schema and metadata.
FLOWS_FILES - This account owns the APEX uploaded files.

If you configured RESTful Web services, then these additional accounts are created:

APEX_REST_PUBLIC_USER - The account used when invoking RESTful Services definitions stored in APEX.
APEX_LISTENER - The account used to query RESTful Services definitions stored in APEX.
