Oracle database plugin HTTP API

The Oracle database plugin is one of the supported plugins for the database secrets engine. This plugin generates database credentials dynamically based on configured roles for the Oracle database.

Configure connection

In addition to the parameters defined by the Database Backend, this plugin has a number of parameters to further configure a connection.

Parameters

• connection_url (string: <required>) - Specifies the Oracle DSN.

• max_open_connections (int: 4) - Specifies the maximum number of open connections to the database.

• max_idle_connections (int: 0) - Specifies the maximum number of idle connections to the database. A zero uses the value of max_open_connections and a negative value disables idle connections. If larger than max_open_connections it will be reduced to be equal.

• max_connection_lifetime (string: "0s") - Specifies the maximum amount of time a connection may be reused. If <= 0s connections are reused forever.

• username (string: "") - The root credential username used in the connection URL.

• password (string: "") - The root credential password used in the connection URL.

• username_template (string) - Template describing how dynamic usernames are generated.

• disable_escaping (boolean: false) - Turns off the escaping of special characters inside of the username and password fields. See the databases secrets engine docs for more information. Defaults to false.

• split_statements (boolean: true) - Indicates that the provided statements specified should be split on semi-colons. Set split_statements to true to specify multiple SQL statements in a single string. Set split_statements to false for complex queries such as stored or inline procedures.

• disconnect_sessions (boolean: true) - Indicates the plugin should disconnect any open sessions before running revocation statements. If disconnect_sessions is false, the revocation statements must include session disconnect logic.

Statements

Statements are configured during role creation and are used by the plugin to determine what is sent to the database on user creation, renewing, and revocation. For more information on configuring roles see the Role API in the database secrets engine docs.

Parameters

The following are the statements used by this plugin. If not mentioned in this list the plugin does not support that statement type.

• creation_statements (string: <required>) – Specifies the database statements executed to create and configure a user. Must be a semicolon-separated string, a base64-encoded semicolon-separated string, a serialized JSON string array, or a base64-encoded serialized JSON string array. The {{name}} and {{password}} values will be substituted.

• revocation_statements (string: "") – Specifies the database statements to be executed to revoke a user. Must be a semicolon-separated string, a base64-encoded semicolon-separated string, a serialized JSON string array, or a base64-encoded serialized JSON string array. The {{name}} value will be substituted. If not provided defaults to a generic drop user statement.
