Why do you need a server routine? You can't call that from a parallel job. What do you believe to be problematic about the solution I already gave you? The lookup will be performed against a one-row virtual Data Set. If you want to go your way, do it in a job sequence. Don't write code. Code has an ...

Fact: Remove duplicates can be performed in any stage that has an input link. The answer to your question may well be dependent on the data type of the keys and the size of the records. I would suggest experimentation to determine whether there is any difference at all. There is a startup (calling)...

Forget Sol2. Anything with code carries a maintenance overhead. Use a Lookup stage to get the comparison value. Perform the comparison downstream of that. Extract2 | | V Extract1 ----> Lookup ----> Filter -----> Extract2 is of the form SELECT 'X', value FROM table (the constant 'X' is important). Ex...

OK, DataStage can do all that. Assuming you're using a parallel job, the Sequential File stage will reject any record that does not match the number/width of fields and can capture these on a reject link. Format you would have to do field-by-field (obviously) in a Transformer stage. In a server job ...

Modulus is more efficient than Hash, because the step of calculating the "hashvalue" is not required - the integer itself is divided by the number of partitions and the remainder is used as the partition for that row. This will guarantee key adjacency. Note, however, that Modulus is only relevant fo...
