Are you using DB2 for your common metadata repository for Information Server? If so, this uses DB2 version 9 (you don't get a choice). What it may also mean is that environment variables such as DB2INSTANCE may be set for that database, and would need to be overridden in a job. Further, version 9 cl...

The technique you need is a variation on one that is called "vertical pivot". Search the forums for techniques. In parallel jobs the most usual technique is to assemble each unique key's record in stage variables in a Transformer stage. Presumably your non-key repeated data will all be in ...

Please advise what the workaround is. I assume it's not as simplistic as forcing you to use an English operating system.

Look in the DataStage BASIC manual. DataStage BASIC can treat a directory as if it were a "table", with the file names in the directory being the "record keys" and the actual files being the "records". In this sense, after you use OPEN or OPENPATH to open the parent dir...

This is called a "blocking operation". It is entirely forbidden in parallel jobs, as it disrupts pipeline parallelism.
