Driver Options
Connections to Oracle require the Oracle Instant Client to be installed.
The ODBC Driver for Oracle uses the ODBC interface to access data in database management systems. It allows an ODBC-compliant application to gain access to one or more data sources. ODBC drivers work under the control of an ODBC driver manager, which is a library that manages communication between the ODBC-aware application and ODBC drivers. The Oracle ODBC Driver uses the Oracle Call Interface (OCI) client and server software to submit requests to and receive responses from the data source. Oracle Net Services communications protocol is used for communications between the OCI client and the Oracle server. Since, the JDBC drivers are available on central maven, we will no longer be uploading the JDBC driver on Oracle Maven. GAV details for ojdbc8.jar from 19.3.0.0: com.oracle.jdbc ojdbc8 19.3.0.0 Here is the list of artifacts available on Oracle Maven repository.
Back in September 15th, 2019 (right before Oracle Code One and Oracle OpenWorld took place) Director of Product Management Kuassi Mensah posted an announcement that took many by surprise but was warmly welcomed: the Oracle JDBC drivers were finally available from Maven Central.
Oracle - Please refer to Oracle’s website for instructions on how to download and setup their official driver: Oracle ODBC driver page
RStudio Professional Drivers - RStudio Server Pro, RStudio Connect, or Shiny Server Pro users can download and use RStudio Professional Drivers at no additional charge. These drivers include an ODBC connector for Oracle databases. RStudio delivers standards-based, supported, professional ODBC drivers. Use RStudio Professional Drivers when you run R or Shiny with your production systems. See the RStudio Professional Drivers for more information.
Package Options
There are packages that either connect via ODBC but do not provide support for DBI, or offer DBI support but connect via JDBC. The odbc package, in combination with a driver, satisfies both requirements.
Sharkoon drivers. Another package that provides both ODBC connectivity and DBI support is ROracle. The current version of dbplyr in CRAN does not yet fully support a connection coming from ROracle, but we are working on it.
Connection Settings
There are six settings needed to make a connection:
- Driver - See the Drivers section for more setup information
- Host - A network path to the database server
- SVC - The name of the schema
- UID - The user’s network ID or server local account
- PWD - The account’s password
- Port - Should be set to 1521

Known Issues
This section will be updated as new issues are found, and when fixes are applied in the development version of the dbplyr package. The issue will be fully removed when the fix is part of of the package’s version in CRAN.
- RJDBC support - Even though it is not considered an issue, we have found a workaround. The approach is to point the current JDBC connection to the Oracle translation inside
