About Oracle Instant Client
Learn how Oracle Instant Client enables applications to connect to a local or remote Oracle Database for development and production deployment.
The Oracle Instant Client libraries provide the necessary network connectivity, as well as Oracle Database client-side files to create and run Oracle Call Interface (OCI), Oracle C++ Call Interface (OCCI), ODBC, and JDBC OCI applications to make full use of Oracle Database.
Oracle Instant Client is commonly used by the Oracle APIs of popular languages and environments including Python, Node.js, Go, Ruby, and PHP. Tools included in Oracle Instant Client, such as SQL*Plus, SQL*Loader, and Oracle Data Pump provide quick and convenient data access. Oracle Instant Client simplifies the deployment of applications by eliminating the need for an Oracle home on the client machines.
Oracle's standard client-server network interoperability allows connections between different versions of Oracle Instant Client and Oracle Database. For certified configurations, refer to My Oracle Support note 207303.1. Tools such as Data Pump may have other restrictions.
Benefits of Oracle Instant Client
