This section describes products that DirectConnect interacts with to provide mainframe access for LAN client requests. For more information about Sybase products, see the Mainframe Connect Overview Guide.
The Mainframe Connect DB2 UDB Option is a CICS transaction that works with DirectConnect for z/OS Option to provide access to mainframe data. It performs these functions:
Supports full read-write, dynamic SQL access to data
Allows applications to use cursors for flexible and efficient result set processing
Permits the use of long-running transactions against mainframe databases
Allows applications to use dynamic events to map SQL to a static plan
DirectConnect for z/OS Option invokes the Mainframe Connect DB2 UDB option to access mainframe data on behalf of its Open Client-based clients, such as:
ASE/CIS
Adaptive Server through remote procedure calls (RPCs)
Enterprise Application Server
Replication Server
The Mainframe Connect Server Option is a programming environment that allows you to create mainframe transactions that Sybase client applications can access. To provide this access, the Mainframe Connect Server Option uses these basic interfaces:
Traditional Open Server programming environment (for new customers and Sybase-heritage customers using new applications)
Remote stored procedure (RSP) programming environment (only for MDI-heritage customers)
These mainframe transactions provide access to virtually any z/OS data source and are used for a variety of functions, including:
Accessing existing mainframe applications
Initiating mainframe batch jobs
Providing source data for data transfer operations
Providing data mapped to a table within the CIS functionality in ASE/CIS (formerly OmniConnect), thus allowing results to be accessed or joined with data from other targets
LAN-side client applications access Mainframe Connect Server Option transactions directly through DirectConnect for z/OS Option or indirectly through ASE/CIS, or through a Sybase ASE RPC.
The Mainframe Connect Client Option is a programming environment that allows you to create mainframe applications that access:
LAN data residing on an ASE or other supported data sources
Other CICS regions
It allows you to treat the mainframe as just another node on a LAN.
Mainframe Connect Client Option uses these APIs:
Traditional Open Client programming environment (for new customers and Sybase-heritage customers using new applications)
Client Services Application (CSA) programming environment (only for MDI-heritage customers)
