Enterprise Server Monitor and Control (ESMAC) enables you to monitor and control CICS-enabled enterprise servers. When Enterprise Server is being used to run CICS applications, an enterprise server corresponds to a CICS region. You can use ESMAC to ensure all the resources required by your CICS application are available, and change and create resources for your application and other applications as necessary. You can also use all the facilities described in the chapter Administering Servers Using ESMAC in your Enterprise Server Configuration and Administration Guide, and in the help topics grouped under Administer a Server Using ESMAC. You should familiarise yourself with the contents of that chapter and the associated help topics before reading this chapter.
