will raise?? KPIT
2:if a table have INDEX and CONSTRAINT why it raise the
performance issue bcoz when we drop the index and disable
the constraint it performed better??KPIT
3:what are unix commands frequently used in informatica??
Hai KPIT,, My Ans will Show you the Way,,,,,,
1) Performance Issue in Informatica: In your
Project ,My Project,,,Any Project Mostly our final
Target was Loading the Data in to Target Table, under
Efficiently in Less time.
Tune the Mapping, Less Active Transformations,Use Best
Loading Option,
Partition the Data,Index less Target Table,,,,,
2)Yes, we drop the index and disable the constraint Perform
Better,That loads the Data based on the Particicular Table
only,Else I will go for Parent,Child test in FK
Relation,Condition in constraint,,,After Loading the Data
You can Configure indexes, constraints on Table.
3)SED-commands,AWK-commands,Dir Commands,File Commands,Copy
Commands only,,
Thanks
