These components interact to enable SQL data access to mainframe
data:
- DB2 II Classic Federation ODBC and JDBC Connector:
Processes function calls, submits SQL requests to a specific data source, and
returns results to the Adapter for JDBC.
- Data source definition: Consists of the name and location
of the data you want to access. The required data source definitions
contain a data source name and communications parameters for TCP/IP or
WebSphere MQ. The data source name identifies a specific application
server or enterprise server that is used to service data access
requests.
- Call Level Interface: Used to bridge from the DB2 II
Classic Federation ODBC or JDBC Connector to the Query Processor task running
in a server.
- The DB2 II Classic Federation Connection Handler: Used to
communicate with an application server or enterprise server. DB2 II
Classic Federation supplies a Connection Handler that supports TCP/IP
implementations that use a Winsock Interface and WebSphere MQ.
The Adapter for JDBC makes SQL data-access requests to a DB2 II Classic
Federation Server and supports metadata access through standard JDBC metadata
calls (used by the JDBC ODA). The adapter uses the DB2 II Classic
Federation ODBC and JDBC Connector.
