DSXchange

As I stated earlier, write and read of the same object in the same job is not supported in parallel jobs, in general. It is a blocking operation, which interferes with pipeline parallelism.

"They" have concentrated their efforts re parallelism in parallel jobs in the recent past. Without managing it yourself (Link Partitioner and external scripts?) I don't think there's much out-of-the-box capability to support TPT functionality in DataStage server jobs. Do you have Enterprise Edition ...

The function ds_uvgetnext() is trying to fetch the next row from a stream input connected from a Hashed File stage. If there were a reference link from the Hashed File stage to the Transformer stage the function would be something likeds_uvgetbykey(). Are you SURE that the stream input is coming fro...

Search the forum to discover the purposes of these. Each is vital in its own way to the job it supports - none is unwanted unless you no longer need the job. If you're looking to recover some disk space, clean out old files from the &PH& directory, and any old files in the directory whose p...

Bienvenue! I think, from your message, that you may have the wrong links to the Transformer stage. The reference link must come from the Hashed File stage. Can you post your job design? For example (wrapped in Code tags) HashedFile : : (reference) : SeqFile ------> Transformer ------> (s...

This is not a good name for a job. It is the default name. Prefer meaningful names. Make sure also that you pass the file name as a parameter to each invocation, and that you ensure that the attach was successful. A job that is not in a runnable state has possibly never been compiled, or aborted, cr...

If you have DataStage client installed, all the manuals are in the Docs subfolder.

Explain the entire job. What you have supplied is insufficient for cogent diagnosis. SIGBUS is one of the standard UNIX signals; type man signal at a UNIX prompt to learn a little more about this particular signal. In general, in parallel jobs, simultaneous write and read to the same object is not p...

The error message will include the generated C++ code, if it gets that far. Otherwise the error message will highlight the syntax error. But you have chosen not to post the error message, so your question is in the class "my car won't start, what's wrong with it?".

JOBCONTROL.H contains a list of possible values returned by each of the DataStage API functions.

My point is that they're not provided - they don't occur in the Routines branch.

You are calling the SP for every row processed. Row buffering means that you are calling it N times at a time, depending on how many rows fit in your virtual Data Set buffers.
