Changing CICS resources and definitions
You can change CICS® resources and definitions in the CICS Explorer® resource editor, which opens in a separate tab group called the editor area.
- When you create a new resource definition, select the Open editor check box in the wizard to open the corresponding resource editor after the wizard completes.
- For resources that already exists, open from a resource or a project view, by either double-clicking the resource name, or selecting Open from the right-click menu.
You can minimize, maximize, resize, or move the editor area in the same way as other tab groups.
If you open a resource in a running CICS region, the changes you can make are limited. However, if you open a resource definition, you can change all editable attributes, just as you can with CEDA.
What's in a resource editor


You can click it to navigate to that JES log, provided that you set up the required connection to the z/OS® UNIX file system.
Editing resource attributes
The attributes tab shows the attributes of a resource. The attributes are grouped in a similar way as they appear in CEDA or the CICSPlex® SM WUI.
For a resource that is defined in a CICS bundle project, only the attributes that you can edit are displayed.
For other resources, editable attribute values are shown in normal text and values that you
cannot edit are disabled. You can hide or show the non-editable attributes by clicking the
Show/hide non-editable attributes icon .
To edit an attribute, double-click the field to select a value from a pre-defined list or enter a new value. For resources in a CICS bundle project, you can use variables when editing the resource definition.
- For a resource that is defined in a CICSplex, the default value is applied for the attribute when you save your changes, if the value is a valid choice.
- For a resource that is defined in a bundle project, the attribute is removed from the definition in the bundle project when you save your changes.
To apply the changes to the definition, you must save them by clicking
or pressing Ctrl+S (cmd+S for macOS). If you have unsaved changes in an editor, an asterisk (*) is displayed in front of the resource name in the editor name tab.Changes to a resource defined in a CICSplex are applied in the CICSplex, and changes to a resource defined in a bundle project are saved in the bundle project.
Acting against a resource with the breadcrumb trail

For resources that are defined in bundle projects, such as the program definition resource, their editors do not show a breadcrumb trail because you do not perform actions against these resources directly. The resources are dynamically generated and modified in CICS regions when you perform actions against the bundles where the resources are defined.
