A CICS-enabled enterprise server equates to a CICS region. On a mainframe, CICS regions are used for a variety of purposes, such as separating departmental applications or projects, and isolating the impact of failures by separating resources into terminal-owning regions, application-owning regions and file-owning regions. MSS-enabled enterprise servers can be used in similar ways.
You do not need to define services, request handlers or implementation packages in order to run migrated CICS applications in an MSS-enabled enterprise server. However, you should not delete the system services and request handlers that are automatically associated with an enterprise server when you create it.
You can, if you wish, run non-CICS applications such as Web services alongside CICS applications in an MSS-enabled enterprise server.
Configuring a CICS-enabled enterprise server is very like configuring any enterprise server - see Enterprise Server Instance Configuration Issues.
