Components of mainframe data access
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.
