Q 1. James has just written a new program following your advice to use checkpoints but now faces another problem. After issuing a checkpoint, the program seems to "forget" its last position in the database as it restarts from the beginning of the database.
You need to help James understand why this happens. Which of the following does he need to know in order for him to fully understand what is happening in the program?

I.     When a checkpoint is issued, all database podition is lost
II.   IMS sets the position to the start of the database
III.  After a checkpoint call, the program needs to reposition itself
IV.  This repositioning can be done by issuing a GU Call to the last segment accessed before the checkpoint
I only
II and III only
IV only
I, II, III, and IV

Q 2. In response to a task you gave to James, he has written the following code to create a DBD using DBDGEN control statements. He was required to make LIBRARY the root segment while BOOKS and MAGAZINES were to be child segments to LIBRARY. You have found something wrong with the code. 

Line1:    PRINT    NOGEN
Line3:    DATASET    DD1=LIB,DEVICE=3380
Line10:    DBDGEN
Line11:    FINISH
Line12:    END

What is/are the corrections that James must make in order for the program to work as expected?
Change BOOKS in line 7 to LIBRARY
Change BOOKS in line 5 to LIBRARY
Change LIBSEG in line 4 to LIBRARY
Change PARENT=0 in line 4 to PARENT=1

Q 3. You can connect to an IMS Database either in DL/I or BMP mode. If you want to connect to databases in a “live” or production environment, when it is important that multiple users can access and update the data at the same time, which of the two modes would be most suitable and why?
DL/I because it is the most popular option
BMP, because the database data sets are allocated in the IMS Control Region, allowing multiple users to update the same databases
DL/I, because it automatically unlocks the Internal Resource Lock Manager (IRLM)
BMP, because it automatically sets DISP=SHR
