List of Java Connection (JDBC) non-db specific properties?

Where can I find a good (maybe official) source (list) of non-db specific properties (keys)?

Properties props = new Properties();
props.put(key, value);
props.put(key, value);
props.put(key, value);
props.put(key, value);
props.put(key, value);
props.put(key, value);
connection = DriverManager.getConnection(path, props);

See the DriverManager.getConnection(String url, Properties info) Javadoc:

info - a list of arbitrary string tag/value pairs as connection arguments; normally at least a "user" and "password" property should be included

Other than that, neither the Java API documentation nor the JDBC 4.3 Specification make any mention of properties that must be supported for DriverManager.getConnection.

Section 9.6.1 does specify a number of properties for javax.sql.DataSource objects, but of those, only "roleName", "user" and "password" make sense for DriverManager.getConnection.

In short, the list of non-db specific properties is "user" and "password" (established by the Javadoc), and maybe "roleName" (though that requires inferring behaviour based on requirements for javax.sql.DataSource). Everything else is driver-specific and you will need to check the documentation of the driver you're using for the properties it supports.

In theory, you can discover properties through Driver.getPropertyInfo​(String url, Properties info). However, its behaviour is - in my opinion - not specified clearly, so support and behaviour varies by driver (some return all properties, some only the minimum set of properties required to connect).
