This section describes options shown in Figure 1-2 that DirectConnect for z/OS Option interacts with to provide mainframe access for LAN client requests.
The Mainframe Connect DB2 UDB Option for CICS and and the Mainframe Connect DB2 UDB Option for IMS can work with Mainframe Connect DirectConnect for z/OS Option to provide access to mainframe data. They perform 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
ASE through RPCs
Enterprise Application Server
JDBC or ODBC applications
Replication Server
The Mainframe Connect DB2 UDB Option for CICS and and
the Mainframe Connect DB2 UDB Option for IMS are hereafter referred
to as the DB2 UDB Options for CICS and for IMS.
The Mainframe Connect Server Option is a programming environment that allows you to create mainframe transactions that are accessible to Sybase client applications. To provide this access, Mainframe Connect Server Option uses traditional Open Server APIs.
These transactions provide access to virtually any CICS and IMS 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 ASE/CIS, 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 a Sybase Adaptive Server RPC.
The Mainframe Connect Client Option is a programming environment that allows you to create mainframe applications that access:
LAN data residing on a Sybase Adaptive Server or other supported data sources
Other CICS regions
To provide this access, the Mainframe Connect Client Option uses traditional Open Client APIs.
The Mainframe Connect Client Option allows you to treat the mainframe as if it were just another node on a LAN.
