D Correct answer
Explanation

The CHNG (Change) call is a Data Communication (IMS TM) call used to modify the destination of an alternate response PCB. It cannot be used with database PCBs. Conversely, GHU (Get Hold Unique), ISRT (Insert), and the database delete call (DLET) are valid database operations.

AI explanation

To answer this question, you need to understand the functions that can be used with IMS database CALLs.

IMS (Information Management System) is a hierarchical database management system developed by IBM. It allows users to store and retrieve data in a hierarchical structure.

Let's go through each option to understand why it can or cannot be used with IMS database CALLs:

Option A) GHU - This option can be used with IMS database CALLs. GHU stands for Get Hold Unit, and it is used to retrieve a specified record from the database.

Option B) DELT - This option can be used with IMS database CALLs. DELT stands for Delete, and it is used to delete a specified record from the database.

Option C) ISRT - This option can be used with IMS database CALLs. ISRT stands for Insert, and it is used to insert a new record into the database.

Option D) CHNG - This option cannot be used with IMS database CALLs. CHNG is not a valid IMS database function. It is not a standard function provided by IMS.

Therefore, the correct answer is D) CHNG. This option cannot be used with IMS database CALLs because it is not a valid IMS database function.
