Oracle Instant Client enables development and deployment of applications that connect to Oracle Database, either on-premise or in the Cloud. The Instant Client libraries provide the necessary network connectivity and advanced data features to make full use of Oracle Database. The libraries are used by the Oracle APIs of popular languages and environments including Python, Node.js, Go, PHP and Ruby, as well as providing access for Oracle Call Interface (OCI), Oracle C++ Call Interface (OCCI), JDBC OCI, ODBC and Pro*C applications. Tools included in Instant Client, such as SQL*Plus, SQL*Loader and Oracle Data Pump, provide quick and convenient data access.
Instant Client RPM packages for Oracle Linux can now be installed from yum.oracle.com for Oracle Linux 8 and Oracle Linux 7. Older releases are available for Oracle Linux 9, Oracle Linux 8, Oracle Linux 7 and Oracle Linux 6.
Whether your applications are in the cloud or on-premise, you can install Instant Client and connect to cloud databases. Follow the normal installation process for your operating system. Some cloud-specific references are shown below.
DigiCert retired the Organizational Unit (OU) field for all public TLS/SSLcertificates to comply with industry standards as of August 2022. This meansthat public TLS/SSL certificates issued by DigiCert will no longer have an OUfield. Refer to MOS note 2911553.1for details.
To avoid disruption to applications connecting to Oracle Autonomous Database onShared Exadata Infrastructure (ADB-S) during the server side certificatechange, you must use hostname based matching of the server certificate.
The following versions of Oracle Instant Client automatically support hostnamebased matching:
Versions: 18.19 (or later), 19.2 (or later), 21 (base release or later), 23.4 (or later)
- Oracle Call Interface (OCI), Oracle C++ Call Interface (OCCI) or ODBCapplications must use one of the above client versions.
- Oracle Database drivers based on Oracle Instant Client or Oracle DatabaseClient (e.g ODPI-C, python-oracledb Thick mode, cx_Oracle, node-oracledb Thick mode,godror, PHP OCI8, PHP PDO_OCI, ruby-oci8, ROracle, and rust-oracle) must usethe driver with a compatible client version from the list above.
ADB-S connection strings contain a hostname "...(HOST=xyz)..." which depends onthe region. For example, in the Chicago region the hostname would be"adb.us-chicago-1.oraclecloud.com". If you have replaced the default hostnamewith an IP address or a custom hostname, then hostname based DN matching willfail. The solution is to add a new entry to your /etc/hosts file using theoriginal ADB-S domain suffix. Your connection string should then use this newname. For example an entry "localtunnel.adb.us-chicago-1.oraclecloud.com"could be created and used.
NetBeans IDE includes built-in support for Oracle Database. You can easily establish a connection from inside the IDE and begin working with the database. This tutorial demonstrates how to use a local installation of Oracle Database 10_g_ Express Edition (Oracle Database XE), a lightweight database that is free to develop, deploy, and distribute.
This tutorial demonstrates how to connect to an Oracle Database XE instance installed on your local system, but the steps can also be applied when you are connecting to a remote instance. If you are connecting to a local instance you need to download and install Oracle Database XE. The installation process is simple and intuitive, but if you have questions, refer to the Oracle Database XE installation guide for your platform.
A common way of interacting with databases is running SQL commands in an SQL editor or by using database management interfaces. For example, Oracle Database XE has a browser-based interface through which you can administer the database, manage database objects, and manipulate data.
Although you can perform most of the database-related tasks through the Oracle Database management interface, in this tutorial we demonstrate how you can make use of the SQL Editor in the NetBeans IDE to perform some of these tasks. The following exercises demonstrate how to create a new user, quickly recreate a table, and copy the table data.
In real life, a database administrator creates custom roles and fine tunes privileges for each role. However, for the purpose of our tutorial, we can use a predefined role, such as CONNECT . For more information about roles and privileges, see Oracle Database Security Guide.
There are several ways to create a table in the database through the NetBeans IDE. For example, you can run an SQL file (right-click the file and choose Run File), execute an SQL Command (right-click the connection node and choose Execute Command) or use the Create Table dialog box (right-click the Tables node and choose Create Table). In this exercise you will recreate a table by using the structure of another table.
In this example, you want the user jim to create a copy of the Departments table in his schema by recreating the table from the hr database. Before you create the table you will need to disconnect from the server and log in as user jim .
Right-click the Locations table node and choose View Data to see the table contents. You will see the contents of the Locations table.You can insert new records and modify existing data directly in this view window.
In our case, we will use a simple "natural join", because both tables have the same "location_id" column that holds values of the same data type. This join selects only the rows that have equal values in the matching location_id column.
This SQL query returns the rows from the Departments table whose location_id values are equal to the values in the matching column in the Locations table, with the results being ordered by the Department name. Note that you cannot insert new records directly in the results of this query, as you could do in the representation of a single table.
You can save the SQL join query as a View (right-click the View node and choose Create View) and run it conveniently whenever you want. For this, the database user should be granted the privilege to Create View that our sample user does not have. You can log in under the system account, grant jim the Create View privilege (with this SQL statement: "grant create view to jim;") and try creating your own view.
If you were following this tutorial, you already used the capabilities of the NetBeans IDE SQL Editor. Here we list several other capabilities of the NetBeans IDE SQL Editor that might be useful to you.
GUI View of Database Tables. When you right-click a table node in the Services window and choose View Data, the IDE displays a visual representation of the table and its data (as shown in the figure above). You can also add, modify, and delete table data directly in this view.
To add a record, click the Insert Records icon and insert new data in the Insert Records window that opens. Click the Show SQL button to see the SQL code for this operation. The table will be automatically updated with the new records.
To modify a record, double-click directly inside any cell in the GUI View of a table and type the new value. Until the change is committed, the modified text is shown in green. To commit your changes, click the Commit Changes icon. To cancel changes, click the Cancel Edits icon.
Keep Prior Tabs. Click the Keep Prior Tabs icon on the SQL Editor toolbar to keep the windows with the results of previous queries open. This can be helpful if you want to compare the results of several queries.
SQL History (Ctrl-Alt-Shift-H). Use the SQL History icon on the SQL Editor toolbar to view all SQL statements that you ran for each of the database connections. Choose the connection from the drop-down list, find the SQL statement that you need and click Insert to place the statement to the SQL Command window.
Run SQL Statements. To run the entire statement that is currently in the SQL Command window, click the Run SQL icon. If you want to run only a part of SQL, select it in the SQL Command window, right-click the selection and choose Run Selection. In this case, only the selected part will be executed.
Open your php.ini file in an editor. Make certain that the extension_dir property is set to the PHP extensions directory. This directory is usually PHP_HOME/ext . For example, with PHP 5.2.9 installed to the root directory of C: , the extension_dir setting should be extension_dir="C:\php-5.2.9\ext" .
*Important: *If there is no such line in php.ini , look in the extensions folder for the OCI 8 extension file. If there is no OCI 8 extension file in your extensions folder, see Installing PHP and the Oracle Instant Client for Linux and Windows for information about downloading and installing OCI 8.
OCI driver packages are available in the same JAR file as the JDBC Thin driver ( ojdbc6.jar ). The selection of which driver to use depends on the interface: oracle.jdbc.OracleDriver for the Thin driver and oracle.jdbc.driver.OracleDriver for the OCI driver. To use the OCI driver, you must also install the Oracle Database Instant Client, because it contains all the libraries required for the OCI driver to communicate with the database.
The troubleshooting tips below describe only a few exceptions that we met. If your question is not answered here, make your own search or use the Send Feedback on This Tutorial link to provide constructive feedback.
This happens because both the GlassFish application server and Oracle Database use port 8080. So, if you want to use both applications at the same time, you need to change this default port of one of them. To reset the default port of the Oracle Database, you can use this command:
This happens when the Service ID (SID) of the database instance provided by the connect descriptor is not known to the listener. There are a number of causes for this exception. For example, it might occur if Oracle Database has not been started (simplest case). Or the SID is incorrect or not known to the listener. If you use a default SID (e.g. for Oracle Database Express Edition, the default SID is XE), this problem is unlikely to appear. The SID is included in the CONNECT DATA parts in the tnsnames.ora file (on a Windows machine, the file is at %ORACLE_HOME%\network\admin\tnsnames.ora ).* You receive the following error:
