FAQS

1)What is GDE?
Ans: Graphical Developement Environment, where we develop graphs or bussiness solutions.


2)What is Co>operating system?
Ans:The Co>Operating System is core software that unites a network of computing resources-CPUs, storage disks, programs, datasets-into a production-quality data processing system with scalable performance and mainframe reliability.


3)What is a Graph?
Ans: A Graph is a combination of Dataset component and Program component connected by flows.


4)What is a Component?
Ans: Components are reusable, powerful modules which are building blocks of a graph.
          They are customizable which is used to do complex transformations.

5)what is component folding?

Ans) It is feature of co operating system that helps combing group of components and run them as a single process.

Pre requisites-

The components must be foldable.

They must be in the same phase and layout.

Components must be connected by straight flow.

6)what is isolation?

Ans) isolation mode identifies a subset of a graph and lets you execute only that subset.This makes debugging faster because you can run a subset of a graph over and over without having a rerun the entire graph.

7)what is  .abinitiorc file?

Ans) To setup abinitio to remotely connect to different server from the existing one ,use .abintiorc file .

Make sure in home directory by typing “cd $home”

Chechk the file by command “ls –la”.

The .abinitorc contains information of different servers in order to remotly connect .if u don’t hav a file in your home directory create a file.

It contains AB_NODES                            @<UNIX servername>:<servername>

               AB_HOME                               @<UNIX servername>:<co>op location >

            AB_AIR_HOME                         @<UNIX servername>:<EME location>

            AB_USERNAME                           @<UNIX servername>: username

            AB_ENCRYPTED_PASSWORD       @<UNIX servername>:password

 

8)what is a custom component? What is program specification file ? what is .mpc file?

Ans) You can build custom components from existing programs or shell scripts and integrate them into the Ab Initio development environments.

A custom component consists of two elements:

·         Your program or shell script

·         A program specification file

Program specification files provide the Co>Operating System with the information it needs to run your program or shell script. Write program specification files as files with .mpc extensions.

9)what is a subgraph?

Ans) A subgraph is a  graph fragment. Just like graphs, subgraphs can contain components and flows. Subgraphs are useful for grouping a graph into subtasks and reusing them.

10)What is redefine component?

Ans) Redefine Format copies data records from its input to its output without changing the values in the data records. You can use Redefine Format to change or rename fields in a record format without changing the values in the records.

11)What is a port?
Ans)Port holds the metadata and also used to connect two components.


12)What is a parameter?

Ans) A parameter is a name-value pair, with a number of additional associated attributes that describe when and how to interpret or resolve the value. Parameters are used to control the behavior of graphs and projects in a controlled and uniform way.
