1) Portray the advantages of DRDA?

The word of top ten mainframe computer[pc] Questions

The vital advantages of DRDA are as per the following.

DRDA is the main convention that supports circulated RDBMS.

One critical advantages given by DRDA is its obviously expressed set of rules for supporting circulated information access.

It is accessible today, and numerous sellers are moving forward on the DRDA.

2) What is IMS?

The term IMS represents Data The executives Framework. It's an information base and exchange the executives framework for Centralized computer. IBM presented it in 1968. From that point forward, it has gone through a few upgradations and adjust some new programming instruments and conditions. IMS is one of two key heritage data sets and exchange the board subsystems from IBM that sudden spike in demand for centralized server working frameworks, and other is CICS.

3) Name the forms of IBM centralized computers have presented on the lookout?

Examine the Historical backdrop of IBM centralized computers (1952-present).

4) What is the requirement for an optional list in IMS?

The optional file is a substitute way into any IMS data set. It tends to be utilized as a document to get the necessary information. An optional file is likewise used to handle a portion type in a succession other than the one that is characterized by the section's critical. An optional list can likewise work a section type in view of a necessity in a reliant portion.

Auxiliary ordering gives a potential chance to meet the different handling necessities of different applications.

5) What is CICS?

The term CICS represents Client Data Control Framework. CICS was presented in 1968 by IBM. CICS gives a MVS climate to create and execute a web-based application. These days, CICS has turned into the most by and large involved server for Web applications. CICS is an exchange handling framework which is likewise called as OLTP (Online Exchange Handling Programming). CICS is an information correspondence framework that upholds an organization that has many terminals.

6) What are the CICS Exchanges?

CICS exchanges play out various activities like characterizing CICS table passages, refreshing records, and so forth, in the CICS locale.

Some significant CICS exchanges provided by IBM are as per the following.

CESN (CICS Execute Sign On)

CEDA (CICS Execute Definition and Organization)

CEMT (CICS Execute Expert Terminal)

CECI (CICS Execute Order Mediator)

CEDF (CICS Execute Investigate Office)

CMAC (CICS Directives for Abend Codes)

CESF (CICS Execute Close down)

CEBR (CICS Execute Transitory capacity Peruse)

7) Characterize CICS interface block?

Any application program needs a connection point to collaborate with the CICS. EIB (Execute Point of interaction Block) is a connection point for application programs that permitted correspondence with the CICS. EIB holds the vital middle of the road data for the execution of a program.

8) Make sense of EIB?

EIB represents Execute Connection point block. It is a control block which is stacked consequently by the CICS for each program.

The EIB is special for an undertaking, and it exists till the term of the errand. It holds a bunch of framework related data connected with the undertaking.

It holds data about exchange identifier, time, date, and so forth, these identifier utilized by the CICS during the execution of an application program.

Each program that executes as a piece of the undertaking approaches a similar EIB.

The runtime information in EIB can be seen by executing the program in CEDF mode.

9) What are the COBOL Coding Sheets?

COBOL was presented in the time of bunch handling. So the COBOL program should have been punched on the card and stacked in the punch card peruser. For this cycle, there is a predefined design of the coding region where the COBOL word is punched. That coding structure is called as the COBOL coding sheet.

As such, the source code of a COBOL program should be written in a configuration that is upheld by the compiler. These projects are sent in Coding Sheets.

The Coding sheet contains 80 person position on each sheet.

10) What is the use of COPYBOOK in COBOL? Might we at some point use a comparative COPYBOOK?

COPYBOOK saves the organization of any record and uses a comparative plan over any program. A determination of code characterizes information structures.

On the off chance that a specific information structure that over and over utilized in many projects, we will try not to change similar information design and use copybooks. We will utilize a Duplicate assertion to remember a copybook for a program. The Duplicate assertion is utilized in the Functioning Stockpiling Area.

Subsequently, we can use a comparative COPY.
