TDJ grows by acquisition as well as the establishment of new companies. <strong>The</strong><br />
diversity of the industries that these companies serve is reflected in the IT<br />
equipment that they deploy to support their daily business needs. Before 1994,<br />
the bulk of the <strong>OLTP</strong> processing for the whole enterprise was done on three<br />
mainframe class systems running <strong>CICS</strong>/ESA regions <strong>with</strong> DB2 databases. In<br />
1994 TDJ decided to move toward an open distributed <strong>OLTP</strong> environment across<br />
its whole enterprise network, integrating all of the existing IT equipment of the<br />
subsidiary companies, making itself ready to take on new IT technologies as they<br />
become available. Such a strategy meets the challenge imposed by the volatility<br />
and dynamics of the business environment in which TDJ competes.<br />
As TDJ has been using <strong>CICS</strong> as its transaction monitor for many years, its<br />
complete satisfaction <strong>with</strong> <strong>CICS</strong> and a pool of in-house <strong>CICS</strong> skilled personnel<br />
influenced its decision to use the <strong>CICS</strong> family of products as the basis on which<br />
to build its new <strong>OLTP</strong> complex. <strong>CICS</strong> for AIX was finally chosen to be the core<br />
transaction monitor. In this chapter we want to share <strong>with</strong> you their experience<br />
in the implementation of their <strong>OLTP</strong> complex. We explore different parts of this<br />
<strong>OLTP</strong> complex, focusing in to show you the detail. You will see how features<br />
such as the high level of <strong>CICS</strong> family interconnection coupled <strong>with</strong> data integrity<br />
have helped TDJ implement its strategy.<br />
