Connecting to Oracle OCI

Oracle OCI supports the following connection types:

• Oracle Server
• OracleTNS
• LDAP

Oracle Server

After you have added the appropriate libraries to your PATH (as described in Before You Connect), set these properties:

• 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

To authenticate via OracleTNS, set these properties:

• 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

To authenticate via the LDAP server, set these properties:

• 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. If your system administrator allows anonymous LDAP logins, your LDAP username and password are not needed.
