Oracle Data Mining Demos include Data Mining sample programs that can help you in learning about Oracle Data Mining APIs.

The Data Mining sample programs illustrate typical approaches to data preparation, algorithm selection, algorithm tuning, testing, and scoring. Each program creates a mining model in the database. All the programs include extensive inline comments to help you understand the code.

Oracle Globalization Demos showcase the features and APIs of the Oracle Globalization Development Kit.

Oracle Globalization Development Kit (GDK) offers a complete framework to ease the development of globalized internet applications. The GDK Example demo illustrates individual functionalities such as, locale-sensitive data formatting, linguistic sorting, locale mapping, locale determination, and language detection. The Oracle Store demo illustrates how the GDK features can be integrated to build a complete multilingual J2EE web application that serves users with vastly different locale preferences.

Oracle Messaging Gateway enables communication between applications based on non-Oracle messaging systems and Oracle Database Advanced Queuing.

Oracle Database Advanced Queuing provides propagation between two Oracle Database Advanced Queuing queues to enable e-business (HTTP through IDAP). Messaging Gateway extends this to applications based on non-Oracle messaging systems. The samples provided for Messaging Gateway illustrate message propagating with Oracle AQ, WebSphere MQ Series, and Tibco Rendezvous using message formats that include JMS, LCR, and XML.

There are seven different samples provided with Messaging Gateway, each located in their own subdirectory. Each sample includes a README file that contains detailed information for setting up and executing the samples.

Oracle Multimedia (formerly Oracle interMedia) is a feature that enables Oracle Database to store, manage, and retrieve images, audio, video, or other heterogenous media data in an integrated fashion with other enterprise information.

Oracle Multimedia extends Oracle Database reliability, availability, and data management to multimedia content in traditional, Internet, electronic commerce, and media-rich applications. It includes several scripts and sample applications that you can use. These consist of OCI, SQL, Java, PL/SQL, and ASP/VBScript sample applications (demos).

Oracle Precompiler Demos show application programmers how to embed SQL operations in C/C++ and COBOL code in a way that is compatible with ANSI standard.

A Pro*C program is a C program containing embedded SQL statements. Oracle Pro*C/C++ and Pro*COBOL Demos offer extensions to support dynamic SQL operations, which are operations that can change in real time. It is also possible to use dynamic SQL operations through PL/SQL code (known as anonymous PL/SQL block) with a Pro*C/C++ and Pro*COBOL application. Typical applications contain much more static SQL than dynamic SQL. The precompiler translates each embedded SQL statement into calls to the Precompiler run-time library (SQLLIB).

Oracle Spatial and Graph Demos provide SQL schema and functions that facilitate the storage, retrieval, update, and query of collections of spatial features in an Oracle database.

Oracle Spatial and Graph is an integrated set of functions and procedures that enables spatial data to be stored, accessed, and analyzed quickly and efficiently in an Oracle database. Spatial data represents the essential location characteristics of real or conceptual objects as those objects relate to the real or conceptual space in which they exist.

Oracle Internet Directory Client Demos show application programmers how to use LDAP C and PL/SQL APIs.

All LDAP operations based on the C API, require clients to establish an LDAP session with the LDAP server. For LDAP operations based on the PL/SQL API, a database session must first initialize and open an LDAP session. The DBMS_LDAP package enables PL/SQL applications to access data located in LDAP servers. The names and syntax of the function calls are similar to those of the C API.

Oracle XML Demos showcase the features of the Oracle XML Developer's Kit (XDK), which is a versatile set of components that enables you to build and deploy C, C++, and Java software programs that process XML.

Oracle Call Interface (OCI) demos include sample C programs to use the OCI APIs.

These programs provide examples of the data types, calling conventions, syntax, and semantics of C.

Oracle C++ Call Interface (OCCI) demos provide database access APIs for applications written in C++. The control classes enable the applications to connect to the database and create resources like statements and resultsets. The data classes contain various types of data. The object classes and methods provide a navigational interface to access and manipulate objects. The Object Type Translator (OTT) can be used to generate the C++ class headers for the data types defined in Oracle database. The installed demos illustrate the use of classes and methods for OTT and OCCI.

Oracle ODBC Driver demos provide basic structure of an ODBC application which can be extended to make a full-fledged ODBC application.

ODBC being a standard, plenty of sample applications may be found in books which discuss the concept of ODBC driver. For Oracle ODBC Driver specific options, see Help while setting up Data Source Name on Windows.

Oracle provides a set of JDBC drivers that you can use for debugging the code and other deployment scenarios. These drivers can access Oracle Database 10g Release 2 or later.

Oracle Database Examples install two Oracle Text knowledge bases, English and French. You can extend the supplied knowledge bases depending on your requirements. Alternatively, you can create your own knowledge bases, in languages other than English and French.

If the sample schemas are not included during an Oracle database installation or during database creation using Database Configuration Assistant, then you can manually install them by running the SQL scripts.

Use one of the following methods to install Oracle Database Examples:

• Installing Oracle Database Examples Using Oracle Universal Installer

• Silent Installation of Oracle Database Examples Using Response Files

• About demo Directories in Read-Only Oracle Homes

You must install Oracle Database Examples in an existing Oracle Database 21c Oracle home.

1. Log in to the computer where Oracle Database is installed.

   On UNIX platforms, log in as the Oracle software owner user (oracle) and set the DISPLAY environment variable.

   On Windows platforms, log in as an Administrator or as a member of the Administrators group to the computer on which you want to install Oracle components. If you are installing on a Primary Domain Controller (PDC) or a Backup Domain Controller (BDC), log on as a member of the Domain Administrators group.

2. Verify that the Oracle Database that you plan to use is accessible.
   Refer to “Accessing the Installation Software” for details.
3. Navigate to the directory where you downloaded the installation files.
4. Extract the contents of the zip file.
5. Run the following command to start Oracle Universal Installer:
   On UNIX platforms:

   $ ./runInstaller

   On Windows platforms:

   Double-click setup.exe.

6. On the Specify Installation Location screen, enter the following:
   • Oracle Base: The Oracle base path appears by default. You can change the path based on your requirement. Specify the Oracle Base path.

     The Oracle base directory is a top-level directory for Oracle software installations.

   • Software Location: In the Software Location field, accept the default value or enter the Oracle home directory path where you want to install Oracle Database Examples. You must install Oracle Database Examples in an existing Oracle Database home.

     Note:

     If you try to install Oracle Database Examples in an Oracle Database home that is different from the current release, then the installation fails with an error.

   If Oracle Real Application Clusters (Oracle RAC) is installed in the Oracle home that you select, then Oracle Universal Installer displays the Grid Installation Options screen. The examples software is installed in the selected Oracle RAC home on all the nodes where it exists. The nodes listed in the table are the nodes on which the Oracle Inventory has registered an installed Oracle RAC home.
   Ensure that each node listed is up and running before you click Next.

   Note:

   On an Oracle RAC installation, the software is installed on all the cluster nodes.
7. On the Perform Prerequisite Checks screen, check for and correct any errors that may have occurred while Oracle Universal Installer was checking your system. If you click Check Again, then you can run the prerequisite check again to see if the minimum requirements are met to carry on with the installation. Click Fix & Check Again, if you want the installer to fix the problem and check the system requirements again.

   Note:

   TheFix & Check Again option generates a script (UNIX only) that sets some system parameters to Oracle-recommended values. You must run the script as the root user. Oracle recommends that you do not modify the contents of this script.
   From the list, select an option:
   • Show All: To get a list of all the prerequirement checks run.
   • Show Failed: To get a list of prerequirement checks that failed.
   • Show Succeeded: To get a list of the prerequirement checks that were successful.
8. Review the information displayed on the Summary screen and click Install.

   Note:

   Click Save Response File to save all the installation steps into a response file. Later, you can use this file for a silent installation.
9. The Install Product screen appears when the product is installing. Installation operations include executing actions such as file copy and adding services on Windows systems and linking on UNIX systems, and executing decision points and calculations.
   The Finish screen appears when the installation is completed.
10. Click Close to exit Oracle Universal Installer.

A silent installation runs in the background and does not require input from the user. The interactive dialogs normally seen by the user are not displayed. Silent installations can be useful if you have to install an Oracle product multiple times on multiple computers.

1. On UNIX platforms:
   $ /directory_path/runInstaller [-silent] -responseFile responsefilename

   Note:

   Do not specify a relative path to the response file. If you specify a relative path, then Oracle Universal Installer fails.

   where:

   • directory_path is the path of the database directory on the DVD or on the hard drive.
   • -silent runs Oracle Universal Installer in silent mode.
   • responsefilename is the full path and file name of the installation response file that you configured.
2. On Windows platforms:
   DRIVE_LETTER:\setup.exe_location setup [-silent] "variable=setting" [-nowelcome] [-noconfig] [-nowait] -responseFile

   where:

   • DRIVE_LETTER: Identifies the full path of the response file.
   • setup.exe_location: Indicates the location of setup.exe.
   • "variable=setting" refers to a variable within the response file that you may prefer to run at the command line rather than set in the response file. Enclose the variable and its setting in quotes.
   • -noconfig: Suppresses running the configuration assistants during installation.
   • -nowait: Closes the console window when the silent installation completes.

Starting with Oracle Database 21c, an Oracle Database installation configures all Oracle Database homes in read-only mode by default.

You must copy some demo directories from ORACLE_HOME to ORACLE_BASE_HOME.
