Q 1 - How many different types of segment can be there in a DLI database?
Answer : B
Explanation
A DL/I database can have 255 different segment types and 15 levels of hierarchy
Q 2 - For FIELD macro statement in DBDGEN, what does TYPE=H parameter specifies?
Answer : D
Explanation
TYPE = H specifies Half word binary data type for the field which we have declared.
Q 3 - What does ACBGEN stands for?
A - Access Control Blocks Generator
B - Access Control Blocks Generator
Answer : B
Explanation
ACB stands for Access Control Blocks Generator. It is used to generate ACBs.
Q 4 - Which function is used for recovering the database?
Answer : A
Explanation
'CHKP' code is used for the Checkpoint function. It is used in the recovery features of IMS.
Q 5 - In PCB which field is used to define to which level an application program is sensitive?
Answer : B
Explanation
Number of sensitivity segments store four bytes binary data. It defines to which level an application program is sensitive. It represents a count of number of segments in the logical data structure.
Answer : A
Explanation
To use command codes, specify an asterisk in the 9th position of the SSA and for Path Call Ignore we code N at 10th position.
Answer : A
Explanation
There is no limit of PCBs allowed in a PSB.
Q 8 - Within the IMS Database, there is only one occurrence of each segment type, but there can be an unlimited number of occurrences of each segment type. State whether true or false?
Answer : B
Explanation
This statement is correct.
Q 9 - When an AND (* or &) operator is used with secondary indexes, it is known as a dependent AND operator. State whether true or false?
Answer : B
Explanation
This is self explanatory.
Q 10 - What error code you will get when program makes a change to the segment’s key field before issuing the REPL or DLET call?
Answer : C
Explanation
This is self explanatory.
