Oracle Instant Client enables applications to connect to a local or remote Oracle Database for development and production deployment. The Instant Client libraries provide the necessary network connectivity, as well as basic and high end data features, to make full use of Oracle Database. It underlies the Oracle APIs of popular languages and environments including Node.js, Python and PHP, as well as providing access for OCI, OCCI, JDBC, ODBC and Pro*C applications. Tools included in Instant Client, such as SQL*Plus and Oracle Data Pump, provide quick and convenient data access.
Deploy applications using Instant Client in the cloud, or connect to a cloud database.
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.
