IMS Explorer projects

An IMS™ Explorer project is a container for storing the resources that you use to plan, analyze, and make changes to your IMS database and to develop IMS applications. Projects are displayed in the Project Explorer view.

You must create an IMS Explorer project before you can use any other IMS Explorer functions.

The resources that you use to make IMS database changes and to develop IMS applications include IMS database descriptions (DBDs) and IMS program definitions (PSBs). You can view and manipulate the resources available in the Project Explorer by using the respective IMS Explorer editor that is associated with each resource type.

When you create a project, the following subfolders are displayed in the Project Explorer to organize these resources:

DBD folder
Holds local copies of the IMS DBD models.
Tip: Opening an IMS database model displays a graphical representation of an IMS database. The model has a .dbd file name extension.

To view the database structure or edit segment field attributes, use the IMS DBD editor. To open the IMS DBD editor, double-click the IMS database model in the Project Explorer.

Expand the database model to see the root and children segment nodes. Right-click a node to launch the Add or Edit Fields wizard.

PSB folder
Holds local copies of the IMS program definition models.
Tip: Opening an IMS program definition model displays a graphical representation of an IMS application program view. The model has a .psb file name extension.

To view or edit the attributes of a PSB and its associated program communication blocks (PCBs), use the PSB summary page. To open the PSB summary page, double-click the program definition model in the Project Explorer.

Expand the program definition model to see three PCB folders:
Alternate PCBs
Expand the Alternate PCBs folder, and right-click on a alternative PCB node to launch the Edit PCB wizard.
Database PCBs
Expand the Database PCBs folder, and right-click on a database PCB node to launch the DB PCB graphical editor.
GSAM PCBs
Expand the GSAM PCBs folder, and right-click on a GSAM PCB node to launch the Edit PCB wizard.

The resources in an IMS Explorer project are stored locally in the IMS Explorer workspace. Changes that are made to the resources in an IMS Explorer project are not automatically propagated to the host mainframe environment or to other repositories.
