getConnection

public OlapConnection getConnection(String databaseName,
                                    String catalogName,
                                    String roleName)
                             throws SQLException

Description copied from class: MondrianServer

Gets a Connection given a catalog (and implicitly the catalog's data source) and the name of a user role.

If you want to pass in a role object, and you are making the call within the same JVM (i.e. not RPC), register the role using MondrianServer.getLockBox() and pass in the moniker for the generated lock box entry. The server will retrieve the role from the moniker.

Specified by:

getConnection in class MondrianServer

Parameters:

databaseName - Catalog name

catalogName - Schema name

roleName - User role name

Returns:

Connection

Throws:

SQLException - If error occurs

Description copied from class: MondrianServer

Extended version of MondrianServer.getConnection(String, String, String) taking a list of properties to pass down to the native connection.

Gets a Connection given a catalog (and implicitly the catalog's data source) and the name of a user role.

If you want to pass in a role object, and you are making the call within the same JVM (i.e. not RPC), register the role using MondrianServer.getLockBox() and pass in the moniker for the generated lock box entry. The server will retrieve the role from the moniker.
