41.In PCB which field is used to store the level of the segment that was processed?
Segment level is known as Segment Hierarchy Level Indicator. It contains character data and is two bytes long. A segment level field stores the level of the segment that was processed. When a segment is retrieved successfully, the level number of the retrieved segment is stored here.
42.In PCB which field stores the area for its own internal linkage related to an application program?
Reserved DL/I is known as the reserved area of the IMS. It stores four bytes binary data. IMS uses this area for its own internal linkage related to an application program.
43.Which SSA provides the name of the segment being used inside the call?
An unqualified SSA provides the name of the segment being used inside the call.
44.What is the length of an unqualified SSA?
A basic unqualified SSA is 9 bytes long. The first 8 bytes hold the segment name which is being used for processing. The last byte always contains space.
45.Where do we code command code in a qualified SSA?
Command code is coded at the tenth position.
46.If a call is successful what value you will get in STATUS-CODE field?
If a call is successful you will get spaces in STATUS-CODE field.
47.Multiple PCBs can not be defined for a single database. State whether true or false?
This statement is incorrect as Multiple PCBs can be defined for a single database.
48.It is not possible for a program to maintain multiple positions in a database using a single PCB. State whether true or false?
This statement is incorrect as a program can maintain multiple positions in a database using a single PCB.
49.For Bidirectional Virtual relationship the logical connection goes from the logical child to the logical parent and it cannot go the other way around. State whether true or false?
This statement is wrong as Bidirectional Virtual relationship allows access in both the directions. The logical child in its physical structure and the corresponding virtual logical child can be seen as paired segments.
50.What does MPP stands for?
MPP stands for Message Processing Program.
