This chapter describes the requirements for installing Oracle Application Express, release 2.2.
This chapter contains these topics:
Oracle Application Express version 2.2 requires an Oracle database that is release 9.2.0.3 or higher.
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:
SQL> STARTUP
If necessary, enter the following command to determine whether the system uses an initialization parameter file (initsid.ora) or a server parameter file (spfiledbname.ora):
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 shared_pool_size parameter:
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 (initsid.ora).
Shut down the database:
SQL> SHUTDOWN
Restart the database:
SQL> STARTUP
Oracle Application Express must have access to Oracle HTTP Server and mod_plsql in order to run. The following products include the versions of HTTP Server and mod_plsql that meet this requirement:
Oracle 9i Database release 2 (9.2) or higher
Oracle 9i Application Server release 1 (1.0.2.2) or higher
Oracle 10g Database companion CD 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
Free space in Oracle Application Express tablespace: 100MB
Free space in SYSTEM tablespace: 85 MB
Free space in Oracle Application Express tablespace for each additional language (other than English) installed: 30MB
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.

Oracle XML DB Developer's Guide for more information about manually adding Oracle XML DB to an existing databaseOracle Text must be installed so that you can use the searchable online Help in Oracle Application Express. By default, Oracle Text is installed as part of Oracle Database.
In addition, make sure 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 drdeflang.sql script, which by default is located in ORACLE_BASE\ORACLE_HOME\ctx\admin\defaults. For example, to run the language preferences script for US English, drdefus.sql:
c:\> sqlplus ctxsys/CTXSYS_password SQL> @c:\oracle\product\10.2.0\db_1\ctx\admin\defaults\drdefus.sql
