Q 1 - What is the predefined pattern for sequential processing?
A - Down the hierarchy then left to right
B - Down the hierarchy then right to left
Answer : A
Explanation
Predefined pattern for accessing data in DL/I is first down the hierarchy, then left to right.
Q 2 - What does DBD stands for?
Answer : A
Explanation
DBD stands for Database Descriptor.
Q 3 - Which parameter specifies the language in which the application program is written in PSBGEN?
Answer : B
Explanation
The LANG parameter specifies the language in which the application program is written, e.g., COBOL.
Q 4 - In PCB which field tells what kind of processing the program is authorized to do on the database?
Answer : C
Explanation
Proc options are known as processing options which contain four-character data fields. A Processing Option field indicates what kind of processing the program is authorized to do on the database.
Answer : C
Explanation
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.
Q 6 - Where do we code command code in a qualified SSA?
Answer : A
Explanation
Command code is coded at the tenth position.
Q 7 - What are the parameters that are used in CBLTDLI call?
Answer : D
Explanation
Function code, PCB mask, Segment I/O Area & SSAs are the parameters used in a CBLTDLI call.
Q 8 - Each occurrence of the root segment, plus all the subordinate segment occurrences make one database record. State whether true or false?
Answer : B
Explanation
This is self explanatory.
Q 9 - Any field can be used as a secondary key. It need not be the segments sequence field. State whether true or false?
Answer : B
Explanation
This is self explanatory.
Answer : A
Explanation
