Also tried that in the sequential mode, it's weird...

There are indexes

I noticed this lock when I browed the SGA trace :

TX - row lock contention

happens when i have more that just a few rows to update.

Does this ring a bell ?

I think it is more efficient to import the contents of the seq file using a single column and then dispatching with an import column stage.

Not very sure but you can call unix command in your routine.

From there you can run a command using sqlplus and thus running a stored procedure or a SQL statement.

Where does the data come from ?

If you want a powerful solution and you're using a DB, I strongly recommend to create a stored procedure function that will handle any possible depth.

From there call the stored procedure in a SQL statement in Datastage.

Also, this is the most efficient method to me.

CDC + Split Insert/update

Hello guys, I have a few questions regarding the CDC stage ? 1) As Suggested by Ray and others, it's better to split inserts and updates.

Still slow...

I wonder if it would be nice to use a change apply stage to rebuild the whole data and then truncate/reload instead of inserting/updating. it seems updating is a huge pain.

What do you think ?

Please note that the source structure and ref structure must be IDENTICAL for the SCD stage to perform. So you might rename one of these columns to get names to match.
