Overview Guide Mainframe Connect Integrated Product Set
|Chapter 1 Introducing Mainframe Connect|
This chapter gives an overview of the Mainframe Connect IPS (Mainframe Connect), which provides a a suite of products that enable access and integration of mainframe data.
The Sybase Enterprise Connect IPS provides a suite of products that enable data access and data movement for a variety of databases where Sybase mainframe components are not required. For more information about Enterprise Connect, see the Overview Guide for the Enterprise Connect IPS.
Mainframe Connect supplies the connectivity tools that allow you to fully integrate your mainframe and LAN-based data sources.
With Mainframe Connect, you can:
Enable client applications to access data stored on CICS, IMS, and MVS systems as if it were Sybase data
Create custom mainframe applications that provide access to data stored on LAN-based servers
Create Open Server gateways to other mainframe database management systems (DBMSs), file systems, and applications
Create custom applications that access mainframe data sources
Mainframe Connect consists of the following components:
DirectConnect for MVS
MainframeConnect for DB2/MVS-CICS
Open ClientConnect for CICS, IMS TM, and MVS
Open ServerConnect for CICS, IMS TM, and MVS
The Mainframe Connect IPS is a suite of products that enables access to both mainframe- and LAN-based data sources. It includes the individual product, MainframeConnect for DB2/MVS-CICS, which is software that resides on the mainframe and works with DirectConnect for MVS to provide dynamic access to mainframe data.
Mainframe Client Connect (MCC) is functionality within DirectConnect for MVS that is used when the mainframe acts as a client and supports access from the mainframe to the LAN over an SNA or TCP/IP network. Open ClientConnect uses MCC.
The following products are related to the Mainframe Connect IPS, but are not part of the product set:
Replication Agent for DB2
Replication Toolkit for MVS
Sybase pioneered data access middleware and has continued to enhance its data access products. Today, Sybase data access products are extremely versatile. Because they easily customized, they are user- and developer-friendly.
Used as stand-alone products or integrated within the Sybase enterprise portal framework, these products enable data access to distributed, client/server and internet technologies, presenting a wealth of data and content driven information to the desktop.
The following figure shows how the components in the Mainframe Connect IPS (shown in bold) and related products (shown in italics) work together to provide access to data on the mainframe.Figure 1-1: How the Mainframe Connect IPS components work together
Although there are many ways your site can use Mainframe Connect to access mainframe data, the scenarios in this section provide high-level examples of the solutions Sybase Mainframe Connect products solve.
Sample solutions include:
As in Figure 1-1, the figures in this section show Mainframe Connect components in bold and the related Sybase products explained in this book in italics.
An insurance company using PowerBuilder needs to manage and update users' profiles in a DB2 database on the mainframe.
The insurance company uses DirectConnect for MVS and MainframeConnect for DB2/MVS-CICS to access DB2.
The following figure illustrates this sample scenario.Figure 1-2: Accessing and changing data in a DB2 database
A telecom company has developed a Visual Basic customer management application that must combine mainframe VSAM data with Informix data.
The telecom company uses ASE/CIS, DirectConnect for MVS, DirectConnect for Informix, and Open ServerConnect application for VSAM data access.
The following figure illustrates this sample scenario.Figure 1-3: Transparently accessing and changing data on a mainframe and in other databases
A retail company is distributing catalog information centrally stored on the mainframe in DB2 to several satellite offices where subsets of the data are stored in Oracle for fast and easy access. Periodic corrections to the catalog information, gathered at the local offices, is replicated back to DB2.
The retail company uses Replication Agent for DB2, Replication Server, Replication Agent for Oracle, and DirectConnect for MVS to replicate between DB2 and Oracle.
The following figure illustrates this sample scenario.Figure 1-4: Processing bi-directional replication between DB2 and other databases within the enterprise
A web-based pet products store--with twenty locations where product orders can be accessed and updated--needs to access orders stored on the mainframe in DB2.
The store uses EAServer, DirectConnect for MVS, and MainframeConnect for DB2/MVS-CICS.
The following figure illustrates this sample scenario.Figure 1-5: Accessing and changing data on the mainframe through an enterprise portal on the web
