Rational Developer for System z, Version 7.6

Defining CICS primary connection regions

A CICS® test environment can consist of several Multi-Region Option (MRO) connected regions. This topic breaks down the various connection regions.

A CICS test environment can consist of several Multi-Region Option connected regions. Over time, unofficial designations have been used to categorize these regions. Typical designations are terminal owning region, Web owning region, application owning region, and data owning region (DOR). A Web owning region is used to implement HTTP communications with CICS, and the Application Deployment Manager CICS Resource Definition (CRD) server must run in this region.

The Application Deployment Manager identifies this region as the CICS primary connection region. The Application Deployment Manager CRD client implements Web service and REST connections to the CICS primary connection region. CICS primary connection region definitions must be configured by opening the Rational® Developer for System z® preferences page and selecting Window > Preferences > Connections.

Connection
  • Type: For operations that require a connection to the CICS Resource Definition server for Application Deployment Manager (for example, creating and editing a manifest for the Application Deployment Manager), this must be set to CICS Resource Definition server via Web services or CICS Resource Definition server via REST. For improved performance or if you are using functions that require resource types that are new in CICS version 4.1 such as bundles, XML transformations, or event bindings, use the CICS Resource Definition server via REST connection type.
    To use the CICS Explorer perspective, you can use one of the CICS Resource Definition server connection types or, for additional options, use the CICSPlex SM Data Interface connection type if it is available and configured at your site.
  • Name: Select the name for the CRD server region.
Location
  • Server address: Type the IP address of the server.
  • Port number.
Authentication
  • User ID: Type the CICS region user ID.
  • Password: Type the password. It will be encrypted when it is saved.
  • Save password: Select this check box if you want Rational Developer for System z to save your password.
CRD server
  • Default primary connection region: You can have multiple CICS environments, each consisting of several regions. Each CICS environment requires a CICS primary connection definition. However, only one of these definitions should be checked as the default CICS primary connection region that will be used by the Resource Definition Editor to retrieve resource attribute default values and as the default target region where resources will be installed.
    Note: When you switch development to a different CICS environment, you should change the default.
