Ans1 : We can use Read Method = “Specific Files” and give the full path of all the file one by one. Alternatively, you can use Read Method = “File Pattern” and specify the wild card.

Ans 2: We can control this using “Missing File Mode” Option. Values are “Ok” to skip the file and continue and “Error” to abort the job.

Ans3: It is important to make sure the meta data matches the record. It would be better to reject bad reject and collect them in “Reject Link”. This can be controlled by “Reject Mode” option. Values are “Continue”, “Fail” and “Output”. “Output” will collect the reject records in a reject link.

create a job that splits the data in the Jobs.txt file into four output files. You will direct the data to the different output files using constraints. • Job name: JobLevels • Source file: Jobs.txt • Target file 1: LowLevelJobs.txt − min_lvl between 0 and 25 inclusive. − Same column types and headings as Jobs.txt. − Include column names in the first line of the output file. − Job description column should be preceded by the string “Job Title:” and embedded within square brackets. For example, if the job description is “Designer”, the derived value is: “Job Title: [Designer]”. • Target file 2: MidLevelJobs.txt − min_lvl between 26 and 100 inclusive. − Same format and derivations as Target file 1. • Target file 3: HighLevelJobs.txt − min_lvl between 101 and 500 inclusive. − Same format and derivations as Target file 1. • Rejects file: JobRejects.txt − min_lvl is out of range, i.e., below 0 or above 500. − This file has only two columns: job_id and reject_desc. − reject_desc is a variable-length text field, maximum length 100. It should contain a string of the form: “Level out of range: ”, where is the value in the min_lvl field. My Question is how do you write the stage variable for reject rows.
