The Complex Flat File (CFF) stage is a file stage. You can use the stage to read a file or write to a file, but you cannot use the same stage to do both. Graphtec wr9000 manual. Prahar mp4 movie download. As a source, the CFF stage can have multiple output links and a single reject link. You can read data from one or more complex flat files, including MVS™ data sets with QSAM and VSAM files. And number of columns may be 3,4,5 or 6 and this is no delimiter variable length text file and need to read is through CFF stage. I have used, used.cfd metadata file types(s) in file option- Record type as variable length data type as text, ascii record delimiter as unix new line. Editing a Complex Flat File stage as a target To edit a CFF stage as a target, you must provide details about the file that the stage will write, define the record format of the data, and define the column metadata. Reject links The Complex Flat File stage can have a single reject link, whether you use the stage as a source or a target. This IBM Counter Fraud Management (ICFM), or ICFM 2, video explains Datastage's Extract Sequential File Stage.
1) When you use sequential file as Source, at the time of Compilation it will convert to native format from ASCII.where as, when you go for using datasets conversion is not required. Also, by default sequential files we be Processed in sequence only. Sequential files can accommodate up to 2GB only. Sequential files does not support NULL values.All the above can me overcome using dataset Stage,but selection is depends on the Requirement.suppose if you want to capture rejected data in that case you need to use sequential file or file set stage.
2)Sequential file is used to Extract the data from flat files and load the data into flat files and limit is 2GB.Dataset is a intermediate stage and it has parallelism when load data into dataset and it improve the performance.
3)Data set mainly consists of two files.
a)Descriptor file which consists of Metada,data location but not actual data itself
b)Data file contains the data in multiple files and one file file per partition.
