Connect to Autonomous Database on Dedicated Exadata Infrastructure with Oracle SQLcl

Tip:

For a "try it out" alternative that demonstrates these instructions, run Task 4: Connect to your autonomous DB using SQL Worksheets from Database Actions, SQLCL and SQL Plus from Lab 2: Configure a Development System in the Oracle Autonomous Database Dedicated Workshop.
SQLcl (Oracle SQL Developer Command Line) is a command-line interface for Oracle Database. It allows you to interactively or batch execute SQL and PL/SQL. SQLcl provides in-line editing, statement completion, and command recall for a feature-rich experience, all while also supporting your previously written SQL*Plus scripts.
To be able to connect SQLCl to an Autonomous Database, the system running SQLCl must have network access to the Autonomous Database. This can be achieved using either of the following ways:

You can use SQLcl version 4.2 or later with Autonomous Database. Download SQLcl from oracle.com.

SQLcl can connect to an Autonomous Database using either an Oracle Call Interface (OCI) or a JDBC thin connection.

SQLcl with Oracle Call Interface

To connect using Oracle Call Interface, use the –oci option, supply the database user name, a password, and the database service name provided in the tnsnames.ora file. For example: 

sql -oci

When connecting using Oracle Call Interface, the Oracle Wallet is transparent to SQLcl.

SQLcl with a JDBC Thin Connection

To connect using a JDBC Thin connection, first configure the SQLcl cloud configuration and then connect to the Autonomous Database.

  1. Start SQLcl with the /nolog option.
    sql /nolog
  2. Configure the SQLcl session to use your Oracle Wallet:
    SQL> set cloudconfig directory/client_credentials.zip
Wallet Password:  **********
  3. Connect to the Autonomous Database:
    SQL> connect username@servicename
password

    For example:

    sql /nolog
