Setting up CICSPlex SM

CICSPlex® SM is the system management component of CICS® and can provide a single-image view of your CICS regions. Set up CICSPlex SM if you have to manage a large number of regions, want to implement workload management, or use platforms, applications, and policies in CICS.

Subtopics

Designing your CICSPlex SM environment
Map out your enterprise to design a CICSPlex SM environment that meets your system management requirements. Your design must include topology information, such as identifying the CICSplexes, CMASs, and WUI server regions that are required, as well as making other design decisions such as what naming convention to follow.
Planning CICSPlex SM setup
CICSPlex SM is installed as part of the product. To set up CICSPlex SM you must decide on a naming convention, plan the security that is required, and which time zones to use in the CICSplex.
Defining the CICSPlex SM configuration and topology
Once CICSPlex SM has been installed, and you have a map of your CICSPlex SM environment, you can define the configuration and topology.
Setting up a CICSPlex SM address space (CMAS)
Perform these steps to make a CICSPlex SM address space (CMAS) operational.
Setting up a CICSPlex SM Web User Interface server
To use the CICSPlex SM Web User Interface, you work through a number of tasks, including specifying parameters, creating data sets, and setting security.
Setting up a CICS managed application system (MAS)
There are a number of steps you must perform so that a CICS system can be known as a managed application system (MAS) to CICSPlex SM.
CICSPlex SM system parameters
You can use a number of system parameters to identify or alter CICSPlex SM attributes. An extrapartition transient data queue called COPR specifies these parameters.
Configuring CICSPlex SM
To configure CICSPlex SM you must create a CMAS and data repository, create a WUI server, and configure your CICS regions. You can organize your regions into groups that logically belong together. You can also create more than one CMAS to provide a highly available environment and create connections between the CMASs.
Customizing the Web User Interface
The WUI offers a number of customization facilities.
Configuring workload management
CICSPlex SM workload management optimizes processor capacity in your enterprise by dynamically routing transactions and programs to whichever CICS region is the most appropriate at the time, taking into account any transaction affinities that exist.
Configuring dynamic routing
You can define a transaction to CICS as either local or remote. Local transactions always run in the requesting region; remote transactions can be routed to any CICS system connected to the routing region. Routing of remote transactions can be dynamic, static, or ATI-controlled.
Routing program-link requests
“Traditional” CICS-to-CICS distributed program link (DPL) calls, instigated by EXEC CICS LINK PROGRAM commands, can be “daisy-chained” from region to region, by defining the program as remote in each region except the last (server) region, where it is to execute.
