Connecting through the Open ServerConnect middleware
product
SAP’s Open ServerConnect supports mainframe applications that
retrieve and update data stored on the mainframe that SAP client
applications can execute. Client applications can connect directly to a
DB2/MVS database through an Open ServerConnect application residing on
the mainframe, eliminating the need for an intermediate gateway like
DirectConnect. (This type of connection is also known as a
gateway-less connection.) In addition, an Open ServerConnect application
presents mainframe Remote Procedure Calls (RPCs) as database stored
procedures to the client application.
To access DB2 data on an IBM mainframe through Open ServerConnect,
you can use the DirectConnect interface to connect through Open
ServerConnect for IMS and MVS.
