Dts Or Linked Server?

  • Hello all :D,

    First of all, i want to give a brief overview what im trying to do.

    We have 2 servers AS/400 and SQL, our AS/400 capacity is already reached it's limit (but our SQL server still have large capacities), so my supervisor ask me to 'remove' old-and-rarely-used data from as/400 to SQL so it will free up some space in AS/400.

    So the scenario is, first we will determine the criteria of the old-and-rarely-used data, and transfer the data by job (that run DTS) overnight, we will run this job for certain period (once a day/week/month).

    In daily basis (we use AS/400), if we searched for particular data and unable to find it in AS/400, we will search in SQL and transfer the data back to AS/400 (approximately, max 1000-2000 rows, 60 columns each).

    What i want to ask is, which one better to transfer data back from SQL to AS/400, DTS or Linked Server (use openquery) or there's any better way? My concern is the transfer speed, we need to transfer the old-and-rarely-used data as soon as possible.

    PS: I'm using SQL Server 2000

    Thanks a lot for your attention,

    Ricky

  • I would say DTS as your situation, moving lots of data around, is what it was built for.

    Having said that, our app syncs with a number of 3rd party apps for which I use linked servers, but I'm usually reading their tables and I'm much more familiar/comfortable with SQL.

  • I agree. It is more efficient using DTS than lined server.

  • Thanks for the reply 🙂

    I'll try to benchmark the transfer speed in development environment.

    Can you all give me some explanation, the drawbacks using linked server(open query) rather than using DTS?

    Because according to my friend, he said that using open query is much more faster than DTS.

  • Ricky,

    I have this same scenario where work (AS400-SQLEE 2000).

    Maybe you can help me.

    I would like to know what components you used in DTS?

    I have some problems, for example, how do I convert the data (Zonned) to compare with the current date (getdate ()) in SQLServer.

    Do you have documentation?
