Specifying segment sensitivity

You can use the IMS PCB editor to define which segments an application program is sensitive to in the database program communication block (PCB) for the hierarchy that contains those segments. An IMS application program can access only data to which it is sensitive. Segment sensitivity can prevent an application program from accessing all the segments in a particular hierarchy. The sensitivity tells IMS which segments in a hierarchy the program is allowed to access.

Before you begin

Open the IMS PCB editor on the PSB that contains the full-function or Fast Path database PCB.

Procedure

  1. Select the database PCB statement.
  2. Open the PCB editor by clicking the Edit PCB Segment button.
  3. To mark a database PCB segment as sensitive, select the check box. Clear the check box to mark the database PCB segment as insensitive.
  4. Click File > Save.
