Who would benefit from this IDEA? Anyone using your product, attempting other than doing a full extract will find it useful.
How should it work?

Enhance 1: Optim process should allow a key list created from an extract process to be saved and used on later DB2 and legacy tables.

Enhance 2: Example provided in the "Optim enhancement.txt"

Idea Priority High
Priority Justification Would be extremely useful in next release.

    Closing as "Already Exists" because of the ways to do this that I've added in the comments above.

    Here is the content of the .txt file with the requirement:

    FIRST ENHANCEMENT:

    In future enhancements a record extract ‘key’ should be saved for matching against separate extracts.

    SECOND ENHANCEMENT:

    Please allow for one or more UNION ALL statements in the SQL part of the DB2 or Legacy extract:

    Notice the parenthesis needed at the beginning.

    (SELECT * FROM XXXXX.TAXXXXXX

    WHERE FIELD_1 = 1

    fetch first 5000 rows only)

    UNION ALL

    (SELECT * FROM XXXXX.TAXXXXXX

    WHERE FIELD_1 = 2

    fetch first 5000 rows only)

    Hi Mary,

    For enhancement 1: Optim has a Point and Shoot list, which is a file containing a list of keys that can be used to initiate the Extract process against a start table. Another choice is, you can use the Optim Insert with a column map to insert only the keys of a table into a smaller table in Db2, and use that as a starting table.

    Does one of those satisfy the Enhancement 1 requirement?

    For Enhancement 2: There are several solutions. But first I should be clear that it appears the same table is used in both parts of the UNION. If not only the first two solutions will work:

    1. I think you can use a Db2 view that is defined as the UNION you show there, as the initial target of the extract.

    2. Or you can do 2 extracts, each extract with the FIELD = 1 or 2 condition, and insert the keys only, to the single result destination.

    3. (Best idea) Or use Optim with a 5000 row limit and the condition on the table being WHERE FIELD IN (1, 2).

    Does one of those satisfy the Enhancement 2?
