Oracle Application Express version 4.0 requires an Oracle database (Enterprise Edition, Standard Edition or Standard Edition One) that is release 10.2.0.3 or higher. Application Express 4.0 can also be used with Oracle Database 10g Express.
Note:You can upgrade the version of Oracle Application Express in Oracle Database Express Edition 10g Release 2 (10.2), by installing Oracle Application Express version 4.0. For more information, see the Oracle Application Express page on Oracle Technology Network (OTN).
Note:Ignore this requirement if your configuration uses non-null values for the database initialization parameters
SGA_TARGET(in Oracle Database 10g and 11g) or
MEMORY_TARGET(in Oracle Database 11g).
Oracle Application Express requires the
shared_pool_size of the target database to be at least 100 MB.
To check the
shared_pool_size of the target database:
Start the database:
If necessary, enter the following command to determine whether the system uses an initialization parameter file (
initsid.ora) or a server parameter file (
SQL> SHOW PARAMETER PFILE;
This command displays the name and location of the server parameter file or the initialization parameter file.
Determine the current values of the
SQL> SHOW PARAMETER SHARED_POOL_SIZE
If the system is using a server parameter file, set the value of the
SHARED_POOL_SIZE initialization parameter to at least 100 MB:
SQL> ALTER SYSTEM SET SHARED_POOL_SIZE='100M' SCOPE=spfile;
If the system uses an initialization parameter file, change the values of the
SHARED_POOL_SIZE parameter to at least 100 MB in the initialization parameter file
Shut down the database:
Restart the database:
To view or develop Oracle Application Express applications, Web browsers must support Java Script and the HTML 4.0 and CSS 1.0 standards. The following browsers are required to develop applications in Oracle Application Express:
Microsoft Internet Explorer 7.0 or later version
Mozilla Firefox 3.5 or later version
Google Chrome 4.0 or later version
Apple Safari 4.0 or later version
Application Express applications can be developed that support earlier Web browser versions, including Microsoft Explorer 6.0.
In order to run, Oracle Application Express you must have access to one of the following:
Oracle Application Express Listener
Embedded PL/SQL gateway
Oracle HTTP Server and
Oracle Application Express Listener is a Java-based Web server. It features file system caching, support for FOP transformations to PDF, offers improved file upload capability, and is certified against Web Logic, Tomcat, and OC4J with Oracle WebLogic Server, OC4J, and Oracle Glassfish Server.
Oracle XML DB HTTP Server with the embedded PL/SQL gateway installs with Oracle Database 11g. It provides the database with a Web server and the necessary infrastructure to create dynamic applications.
Oracle HTTP Server uses the
mod_plsql plug-in to communicate with the Oracle Application Express engine within the Oracle database. The following products include appropriate versions of HTTP Server and
Oracle Database 10g Companion CD release 2
Oracle Database 11g release 1 or 2

Oracle Application Express disk space requirements are as follows:
Free space for Oracle Application Express software files on the file system: 450 MB if using English only download (apex_4_0_en.zip) and 1 GB if using full download (apex_4_0.zip).
Free space in Oracle Application Express tablespace: 185 MB
Free space in
SYSTEM tablespace: 100 MB
Free space in Oracle Application Express tablespace for each additional language (other than English) installed: 75 MB
Oracle XML DB must be installed in the Oracle database that you want to use. If you are using a preconfigured database created either during an installation or by Database Configuration Assistant (DBCA), Oracle XML DB is already installed and configured.
See Also:Oracle XML DB Developer's Guide for more information about manually adding Oracle XML DB to an existing database
Tip:The installer does a prerequisite check for Oracle XML DB and will exit if it is not installed.
Tip:The installation of Oracle XML DB creates the user ANONYMOUS. In order for Oracle Application Express workspace provisioning to work properly, the ANONYMOUS user must not be dropped from the database.
Oracle Text must be installed in order to use the searchable online Help in Oracle Application Express. By default, Oracle Text is installed as part of Oracle Database.
In addition, ensure that the default language preferences for Oracle Text have been installed. To install the Oracle Text default language, log in to the Oracle database where you plan to install Oracle Application Express and run the appropriate
.sql script, which by default is located in
\ctx\admin\defaults. For example, to run the language preferences script for US English,
c:\> sqlplus /nolog SQL> connect ctxsys Enter password: password SQL> @c:\oracle\product\10.2.0\db_1\ctx\admin\defaults\drdefus.sql
See Also:Oracle Text Application Developer's Guide for more information on Oracle Text and "Enabling Network Services in Oracle Database 11g" for your configuration scenario.
Tip:The installer does a prerequisite check for Oracle Text and will exit if it is not installed.
Oracle Application Express requires the PL/SQL Web Toolkit version 10.1.2.0.6 or later. For instructions on determining the current version of the PL/SQL Web Toolkit, and for instructions on installing version 10.1.2.0.6, please review the
