Oracle Application Express release 4.2 requires an Oracle database (Enterprise Edition, Standard Edition or Standard Edition One) that is Release 10.2.0.4 and later. Oracle Application Express release 4.2 can also be used with Oracle Database Express Edition 10g Release 2 (10.2) and later. The Oracle HTTP Server is not included with the distribution of Oracle Database Express Edition.
Note:You can upgrade the version of Oracle Application Express in Oracle Database Express Edition 10g Release 2 (10.2) and later, by installing Oracle Application Express release 4.2. For more information, see the Oracle Application Express Learn More page on the Oracle Technology Network (OTN).
Note:Ignore this requirement if your configuration defines specific memory target values for the database initialization parameters
SGA_TARGET(in Oracle Database 10g and 11g or later)
MEMORY_TARGET(in Oracle Database 11g or later).
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 value of the
SHARED_POOL_SIZE parameter to at least 100 MB in the initialization parameter file
Shut down the database:
Restart the database:
Microsoft Internet Explorer 7.0 or later
Mozilla Firefox 14 or later
Google Chrome 21 or later
Apple Safari 5.0 or later

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.
