    data handling issue

    Hi all,
    I'd like to have you opinion about the following performance/design
    issue:

    a logging system is generating a lot of records every our,(about
    500k/day)
    I need to store them in a huge Oracle RAC system
    a Java web application connects to the data and executes queries on
    them, mainly on last entered set of records
    queries on informations stored more then 3 months ago are quite rare

    as first guess I managed to store them in a table indexed by a
    primary key, let's say in the table 'LOGS'
    the problem is that table is going to grows very big,

    have you got 'best practice' ideas to handle the situation in a better
    way?

    I thought about moving data priodically in a 'LOGS_ARCHIVE' table ,
    for example using a Oracle job
    is it necessary?
    PS I can't use Oracle standard file archiving support, I need data to
    stay on tables

    thanks in advance

    I always find it strange that we see requests like this. Sort of along the
    lines of "I am building this huge Oracle database and I don't know much
    about Oracle but..." Wouldn't one get people on the project who have some
    knowledge and expertise on Oracle? It just strikes me as very odd.

      My guess is the manager gets the cheapest programmer available and
      keeps asking him to take over responsibilitie s of the more
      knowledgable folks as they are laid off. Of course then the manager
      hears about outsourcing to India at even lower rates and the pattern
      begins again. 8^)

      But seriously, I'm as puzzled as you are.

        My experience in computer science is limited, I only have a First
        Class Masters degree in Electronics Engineering, but I'm confident
        with hard working and studying I can become 'good' as you

        plus, I'll be much more professional answering in Usenet

        thanks anyway

            I am sure you are a hard working good person. My comment has nothing to do
            with your personality, but rather why people do this. (more the fault of
            the manager from not getting experienced people for a task that needs an
            experienced person) It is sort of like I've been hired to design a Boeing
            747 and I have experience building paper airplanes. There is quite a gulf
            there in needed experience.

              Jim,
              I do have some experience, maybe this is the most complex project I
              have dealt with, but we have enough time and resources to improve the
              skills if required..
              anyway the project is not so mission critical, even if a lot of data
              are expected, and from a general point of view the factors are quite
              calibrated

              anyway we used range partitioning to handle the issue

              best regards
              jc

                The point is that there is little to offer in way of answering your
                original question. And the little bit of information you did provide
                sounds so much like the many
                just-out-of-college-web_guru-now-dba-on-Oracle posts that we have to
                wonder. Now with your additional information, I really wonder why the
                manager hired you when there are experienced Oracle folks around. Try
                rereading my post, I was making a comment about the hiring manager,
                not you.

                But since you brough it up. If you are the DBA, yet you cannot find
                out how to add space to the databasebase as needed, or what partioning
                of tables can get you, or any of a dozen other DBA tasks I have to
                wonder.

                You never mentioned ORACLE version, hosting platform. You only hint
                about size (500k records per DAY is not necessarily BIG).


                (Boy I've been in a grouchy mood recently.)

                Finally, FYI, this group is not really supported. The official groups
                are
                comp.databases. oracle.server
                comp.databases. oracle.misc
                comp.databases. oracle.tools
                comp.databases. oracle.marketpl ace

                Some servers still carry this group, but you'll get wider support
                posting in the appropriate one of those four.

                Sorry you took offense. Rephrase your question and you'll get a better
                response.

                good luck.
