DataStage Scenario - Problem10

Goal :  Get the max salary from data file ( Seq file )

We know that max function is use to get the max value in a column of a table, but here you have to design a datastage job which get the max value from seq file.



Input Seq File :

DataStage Scenario - Problem9

Goal : Distribute the data is below requirement

Input file's data is distributed like 1st 3 row in file1, next 3 row in file2, next 3 rows in file3 again next 3 rows in file1 and continues.

DataStage Scenario - Problem8

Goal : Distribute the data as below condition -

Given : FileA and FileB contains some data in single column.
Target : File_A : Which contains the data which is available in A but not in B
Target : File_B : Which contains the data which is available in B but not in A
Target : File_AB : Which contains the data which is available in A and B Both

DataStage Scenario - Problem7

Goal : Divide the input into 3 columns

source  

c1      
c2      
c3      
c4
c5
c6
c7
c8

Removing last or more character of string

Want to remove last character from a string in Linux, We can do this with help of SED commands.

Use this

a) Remove last char
sed 's/.$//' input
or
sed 's/.\{1\}$//' input

i.e. -
echo 123456 | sed 's/.$//'
12345

echo 123456 | sed  's/.\{1\}$//'
12345

Datastage Common Errors and Solutions

1.     While running ./NodeAgents.sh start command... getting the following error: “LoggingAgent.sh process stopped unexpectedly”

SOL:   needs to kill LoggingAgentSocketImpl

              Ps –ef |  grep  LoggingAgentSocketImpl   (OR)

              PS –ef |               grep Agent  (to check the process id of the above)

2.     Warning: A sequential operator cannot preserve the partitioning of input data set on input port 0

SOL:    Clear the preserve partition flag before Sequential file stages.
