This section shows how to set up ODBC connectivity and configure DSNs on macOS.

Minimum macOS Version

The CData ODBC Driver for Oracle driver requires macOS Sierra (10.12) or above.

Licensing the Driver

In a terminal, run the following commands to license the driver. To activate a trial, omit the <key> input.

cd "/Applications/CData ODBC Driver for Oracle/bin"
sudo ./install-license.sh <key>

You'll be prompted for a name and password. These refer to your name and your machine's password.

Before You Connect

To connect to Oracle, you will first need to update the appropriate environment variable. This variable must contain a folder location that includes the Oracle OCI Library assemblies, which are shipped alongside the driver. The correct environment variable depends upon your platform:

• Windows: The native libraries should be on your PATH. Note that the VC++ 2017 Redistributable package is required to load the OCI libraries.
• Mac: The native libraries should be on your DYLIB_LIBRARY_PATH.
• Linux: The native libraries should be on your LD_LIBRARY_PATH.

These native libraries can be found in the lib folder inside the installation directory of the driver.

Connecting to Oracle OCI

The following connection types are available:

• Oracle Server
• OracleTNS
• LDAP

Oracle Server

After you have added the appropriate libraries to your PATH, set the following to connect:

• User: The user Id provided for authentication with the Oracle database.
• Password: The password provided for authentication with the Oracle database.
• Port: The port used to connect to the server hosting the Oracle database.
• ServiceName: The service name of the Oracle database. You can obtain this value by querying global_name (select * from global_name) using the Oracle SQL*PLUS command line.
• Server: The host name or IP address of the server hosting the Oracle database.

OracleTNS

Set the following connection properties prior to connecting:

• User: The user Id provided for authentication with the Oracle database.
• Password: The password provided for authentication with the Oracle database.
• DataSource: The Oracle Net Services Name, Connect Descriptor (known also as TNS Connect String), or a connection name that identifies the database to which to connect. You should be able to find these values in your tnsnames.ora file.

For example,

DataSource='(DESCRIPTION=(ADDRESS=(protocol_address_information))(CONNECT_DATA= (SERVICE_NAME=service_name)))'

LDAP

In this scheme, you need to authenticate to the LDAP server. Set the following connection properties to connect:

• User: The user Id provided for authentication with the Oracle database.
• Password: The password provided for authentication with the Oracle database.
• LDAPUri: The LDAP URI used to connect to the LDAP server.
• LDAPUser: The User account for LDAP server.
• LDAPPassword: The password for the LDAP user.

Your connection string should look similar to this:

LDAPUri=ldap://myldap.com:389/SERVICE_EXMPL,cn=OracleContext,dc=example,dc=com; User=ORACLEUSER; Password=OracleUserPassword;

Note that this connection type requires both your Oracle and LDAP usernames and passwords. Your system administrator may allow anonymous LDAP logins, in which case your LDAP username and password are not needed.

Uninstalling the Driver

The easiest way to uninstall the driver is to open a terminal and run the included uninstall.sh script, located in the installation directory. For example:

cd "/Applications/CData ODBC Driver for Oracle"
sudo ./uninstall.sh

Note: The script needs to be run from the installation directory.
