    Get rid of the hash files... the one thing I HATE most about DataStage are hashfiles... spent weeks fixing them.

    Replace them by a nice database table and some db lookups.

    Unhappy

    I know, but the company near which I carry out the thesis uses them and I hoped that, without having to modify their job excessive, it was possible to replace them with something equally fast? (not creed of being able to create tables to my discretion and is not for my choice).

    No hash file substitute available right now (not in 2.5, not in 3.0) ... and if it's up to me never will make it in the general distribution ... too many ways to burn yourself.

    Think tables and lookups. If the data is small and you only want to lookup, you could even think of putting the data in text files and use them together with stream lookup e.g.
