4 Configuration Tasks When Installing from the Database

Oracle Application Express is installed by default with Oracle Database 11g Release 1 (11.1) and later. This chapter describes required postinstallation configuration tasks for Oracle Application Express when installed with Oracle Database 12c or later in the standalone and multitenant architecture.

The instructions in this chapter apply to both new and upgrade installations. To learn more, see "Upgrading from a Previous Release of Oracle Application Express".


This chapter applies to installations in Oracle Database 12c in the multitenant architecture and non-CDB (or standalone) architecture. For more information on multitenant architecture, see "Part VI" in Oracle Database Concepts 12c Release 1 (12.1). For more information on different installation scenarios relating to Application Express in an Oracle Database 12c Release 1 (12.1) multitenant architecture, see Chapter 3, "Utilizing the Multitenant Architecture".

4.1 About Patching Oracle Application Express

If you are already running Oracle Application Express, then check the Oracle Application Express page on the Oracle Technology Network (OTN) at the following URL for information about patch set releases or later releases of Oracle Application Express:


Upgrading to Oracle Database 12c Release 1 (12.1) will not patch Oracle Application Express. To learn more about downloading and installing Oracle Application Express from Oracle Technology Network (OTN) see "Downloading from Oracle Technology Network" in Oracle Application Express Installation Guide for Oracle Application Express release 4.2.

4.2 Recommended Pre-installation Tasks

Before installing Oracle Application Express, Oracle recommends that you complete the following steps:

  1. Review and satisfy all Oracle Application Express installation requirements. See "Oracle Application Express Installation Requirements".

  2. Shut down any existing Oracle Database instances as well as Oracle-related processes.

    Shut down any existing Oracle Database instances with normal or immediate priority, except for the database where you plan to install the Oracle Application Express schemas. On Oracle Real Application Clusters (Oracle RAC) systems, shut down all instances on each node.

    If Oracle Automatic Storage Management (ASM) is running, shut down all databases that use ASM except for the database where you will install Oracle Application Express, and then shut down the ASM instance.

    You can use the Windows Services utility, located either in the Windows Control Panel or from the Administrative Tools menu (under Start and then Programs), to shut down Oracle Database and ASM instances. Names of Oracle Databases are preceded with OracleService. The Oracle ASM service is named OracleASMService+ASM. In addition, shut down the OracleCSService service, which ASM uses. Right-click the name of the service and from the menu, choose Stop.

  3. Back up the Oracle Database installation.

    Oracle recommends that you create a backup of the current installation of Oracle Database installation before you install Oracle Application Express. You can use Oracle Database Recovery Manager, which is included the Oracle Database installation, to perform the backup.
