Hi complex flat file is some thing that we get from an IBM/AS400 machine etc in order to use u need to have a cobol copy book which is used to load the meta data. You also need to have a data file for this cobol copy book. All fields from cobol copy book are usually chars for furthe r information read the parallel job developers guide from ascential. How to expand ship in starbound. Jun 13, 2020 The complex flat file allows reading on a mainframe machine similar to a header, MVS data sets, and trailer structured files from complex file structures. External Source allows reading data from multiple source programs to output. Lookup File Set is similar to File set Stage. Partitioned hashed file can be used for lookups. Database Stages.
InfoSphere DataStage is also flexible about meta data. Netsupport manager 12 keygen serial. It can cope with the situation where meta data is not fully defined.
You can define part of your schema and specify that, if your job encounters extra columns that are not defined in the meta data when it actually runs, it will adopt these extra columns and propagate them through the rest of the job.
This is known as Runtime Column Propagation (RCP).
RCP can be enabled for a project via the Administrator client, and set for individual links via the Output Page Columns tab for most stages, or in the Output page General tab for Transformer stages.
You should always ensure that runtime column propagation is turned on if you want to use schema files to define column meta data.

When we run the Datastage Jobs, the columns may change from one stage to another stage. At that point of time we will be loading the unnecessary columns in to the stage, which is not required.

If we enable RCP, we can send the required columns into the target.
RCP is mostly useful when we use reusable job where different metadata comes into the picture. Realflow node license crack.
Using RCP With Sequential Stages
Runtime column propagation (RCP) allows DataStage to be flexible about the columns you define in a job.
If RCP is enabled for a project, you can just define the columns you are interested in using in a job, but ask DataStage to propagate the other columns through the various stages.
So such columns can be extracted from the data source and end up on your data target without explicitly being operated on in between.

Sequential files, unlike most other data sources, do not have inherent column definitions, and so DataStage cannot always tell where there are extra columns that need propagating.
You can only use RCP on sequential files if you have used the Schema File property to specify a schema which describes all the columns in the sequential file. Watchguard feature key keygen crack.
You need to specify the same schema file for any similar stages in the job where you want to propagate columns. https://kotyy.over-blog.com/2020/10/keyboard-cleaner-for-mac.html. Stages that will require a schema file are:
- Sequential File
- File Set
- External Source
- External Target
- Column Import
- Column Export
