After that, we should distribute the file systems to remove bottlenecks, if any. Then we should isolate and solve the problems, one by one. Secondly, we should not use only one flow for performance testing. In order to improve performance of Datastage jobs, we have to first establish the baselines.

We can use the option, as allow duplicate = false.ġ2) What steps should be taken to improve Datastage jobs? Such routines are also created in DS manager and can be called from transformer stage.ġ1) What is the method of removing duplicates, without the remove duplicate stage?ĭuplicates can be removed by using Sort stage. We can write parallel routines in C or C++ compiler. There are three types of routines such as, parallel routines, main frame routines and server routines.ġ0) How can you write parallel routines in datastage PX? Routines are basically collection of functions that is defined by DS manager. Datastage is more user-friendly as compared to Informatica. Also, Informatica is more scalable than Datastage. While, there is no concept of partition and parallelism in informatica for node configuration. In datastage, there is a concept of partition, parallelism for node configuration. The two tables are joined on the basis of Primary key columns in both the tables.ħ) Differentiate between data file and descriptor file?Īs the name implies, data files contains the data and the descriptor file contains the description/information about the data in the data files.Ĩ) Differentiate between data stage and informatica? The truncated data error can be fixed by using ENVIRONMENT VARIABLE ‘IMPORT_REJECT_STRING_FIELD_OVERRUN’. In Data stage 7.5 many new stages are added for more robustness and smooth performance, such as Procedure Stage, Command Stage, and Generate Report etc.ĥ) In Data stage, how you can fix the truncated data error? To import the DS jobs, dsimport.exe is used and to export the DS jobs, dsexport.exe is used.Ĥ) What is the difference between Data stage 7.5 and 7.0?

We can populate a source file in many ways such as by creating a SQL query in Oracle, or by using row generator extract tool etc.ģ) Name the command line functions to import and export the DS jobs? It has become an essential part of IBM WebSphere Data Integration suite.Ģ) Explain how a source file is populated?

It is a program for Windows servers that extracts data from databases and change them into data warehouses.

This file contains a line RollNo which is usually concatenation of 4 set width columns which we have to divided and examine. Input File:Below is certainly the Input file which we are usually heading to make use of in our job.

How are the information splitting into two or even more result columns.Here, I demonstrate How to read through a Fixed Width Smooth file from Sequential Document StageA. For reading a Fixed Width Level file, you should know the format of Fixed width data. If we have got a fixed size Flat file, we can learn it via Sequential Document stage only, no need to use Import Phase.
