Some more design tips for DataStage Job Development


• Common information like home directory, system date, username, password should be initialized in a global variable and then variable should be referred everywhere.

• Stage Variables allow you to hold data from a previous record when the next record, allowing you to compare between previous and current records. Stage variables also allow you return multiple errors for a record of information. By being able to evaluate all data in a record and not just error on the first exception that is found, the cleanup of data is more efficient and requires less iteration.
