DSXchange

Not columns. A Copy stage (passive) can quite happily drop (not transfer) some columns. This does not represent a change to the data.

What do YOU think the difference between the two scenarios is? In particular, under what circumstances might the second be appropriate?

Is the Scale value in the metadata set to 6?

Are these, or some of them, materialized views?

How complex are the constraints in the query? How complex are the join criteria?

You can put it in any folder you like. The repository is entirely customisable. The location of a stage type does not affect its other properties.

If you didn't understand that, then your best course it to take the IBM class "DataStage Essentials" or some equivalent. This is so fundamental a concept to running parallel jobs.

Means that I can use following combination.

10 cpu =20 Nodes and 9 cpu =18 nodes.

No it doesn't. It means
10 cpu = 5 nodes and 9 cpu = 5 nodes.

This is singularly useful when the developer is red-green colour blind. I had such a client once, and changed the good/bad colours to yellow and purple, which he could see and differentiate.

Curious. Looks like DS is checking the HA status for some reason. Can you review your installation log to make sure that no HA piece was enabled? Contact support to find out how to disable it, and do let us know.

Not unless the job design reports it.

There is no flag. You could, of course, determine the most recent "job started" event by constraining on max of TIMESTAMP and event type.

Data Rule Definitions can be created in either DataStage or Information Analyzer. They are compatible - rule definitions published into the common metadata repository by one tool can be used by the other.

Thanks, Eric. Alas my client seeks to have a fully automated process.

Show us what your data look like in vi or cat -vt or similar.

Note that istool import ... -fasttrack '<options>' only imports from an assets archive (a ".isx" file), it does not appear to support CSV format.
