SCLM Explorer

The SCLM Explorer utility provides an interactive facility for viewing the relationships between components of a project. You can select as a starting point any architecture definition or part member and then navigate up or down the hierarchy of related ARCHDEFs or parts.

With SCLM Explorer, you can:

Display a list of all components, or selected components.
Select a component and identify its immediate relations (parent or child).
Select a component and identify its related executable components.

In addition, the utility provides some impact analysis capability by identifying the "buildable" or "linkable" components that would be affected by planned changes to a lower-level component.

Component relationships are generally hierarchical. For example:

ARCHDEFs can include source parts
Source parts include other source parts
ARCHDEFs can include other ARCHDEFs

Figure 1 shows the panel that is displayed when you select Option 12, SCLM Explorer, from the SCLM Utilities panel.

Select option 2 to list the components in the project. Select option 3 to list the architecture definitions in the project.

The following commands are available:

U (up): Show the parents of the selected component
D (down): Show the child components
L (LMOD): Show related executable components (load modules)

Parent or child relations can be followed until no further relations remain. Position the cursor on one of the displayed components and press Enter to show its parent or child components. Parent relationships will generally terminate at a high level architecture definition (HLMAP), while child relationships usually terminate with a low-level copybook source or macro part.

As the relationship hierarchy is navigated, a 'path' description is maintained, identifying the chain of selected parts.

The relationship information is extracted from the accounting files in the project database and stored in a set of ISPF tables. The tables are populated by the FLMUEXTR utility (see FLMUEXTR—the SCLM Explorer batch utility). The data displayed in SCLM Explorer therefore reflects the status of the project at the time the batch utility was last run.

The extraction process is controlled by the following options on the SCLM Explorer panel:

Option 0 is used to specify the name of the ISPF table library. Your SCLM Administrator can provide you with the library name.
Option 1 is used to build the JCL for a batch job to extract data and populate the ISPF tables.
