| shikha | Re: IMS DB Questions Some questions for preparation of Operational Information Management System (IMS) DB (/Data Base) Interview is as follows: What is a hierarchy path? What is a root segment? What are twin segments? Define segment occurrence. What is a database record? What is the limitation on the number of levels in a DL/I database? How many segment types can you have in a DL/I database? What are the control blocks in IMS? What are common DLI functions? What are the command codes and their purposes? What is the use of PROCOPT? What is multi-positioning? Define a search field. What is a GOBACK statement? Define a call statement. What is the function of a GU call? What is the function of a GHU call? What is the function of SSA? Explain index pointer segment. Which is the first statement in COBOL-IMS programs? What is the return code you get after a successful IMS call? What is the use of Sparse Sequencing? Explain Logical relationship. What are logical twins? What is a concatenated segment? Explain DL/I log. What is a checkpoint? Which database processing is very fast? Which database is difficult to manage? Through which segment all dependent segments are accessed? How can we access the data in IMS DB? What is the predefined pattern for sequential processing? For FIELD macro statement in DBDGEN, what does TYPE=P parameter specifies? For FIELD macro statement in DBDGEN, what does TYPE=X parameter specifies? What does SENSEG stands for? Which parameter specifies the language in which the application program is written in PSBGEN? Which is used to pass the control back to the IMS control program? Which function is used to get a unique record for update purpose? Which function is used to retrieve segment occurrences in sequence subordinate to an established parent segment? Which function is used for recovering the database? In PCB which field is used to store the level of the segment that was processed? In PCB which field stores the area for its own internal linkage related to an application program? Which SSA provides the name of the segment being used inside the call? What is the length of an unqualified SSA? Where do we code command code in a qualified SSA? If a call is successful what value you will get in STATUS-CODE field? Multiple PCBs cannot be defined for a single database. State whether true or false? It is not possible for a program to maintain multiple positions in a database using a single PCB. State whether true or false? 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? What does MPP stands for? What is the maximum of key fields and search fields allowed in a segment? What is the maximum number of PCBs allowed in a PSB? What are the two ways in which DL/I interface can be invoked? How many root segments do we have per database record? What is the maximum number of fields allowed per segment and what is the maximum number of fields per database? |
