Oracle 10g and Datawarehousing

Hi,
I have come across a concept of real-time datawarehousing and learnt that there is a feature in Oracle 10g database which supports it.What are those features of Oracle 10g which support the real-time datawarehousing?
Thanks

For example:
Oracle database 10g Data Warehousing.

To my mind, full answer for your question (design, features, etc).

  • Important differences between oracle 10g and 11g

    Hi friends, can anyone tell me (pointwise) what are the major (and minor) differences between Oracle 10g and 11g.
    Please point me to some documents if possible.
    Thanks in advance

    The name of the link says it all: "top_features."
    In short it is Oracle's list of what they have for marketing and sales reasons designated "top features."
    It is not intended to be, and is not, a complete list of features. Often the features Oracle does not
    talk about are the most important.
    Let me give you some examples. I have never seen Oracle announce DBMS_XPLAN as a new feature
    yet you should not run an explain plan without it. Neither have I ever seen Oracle announce the new
    NO_DATA_NEEDED predefined exception. I have listed literally hundreds of new features you will not
    find in Oracle's new features docs.
    I did a presentation at OpenWorld this year as part of the unconference titled "New Features in
    Database 11gR2 that Oracle will not announce." It was easy to prepare a one hour presentation with
    little fear of being proved incorrect. As I turned out only one of the features I presented was mentioned
    by Oracle.
    You can find the presentation slides here:

  • External table in Oracle 10g and Windows server 2003 problem

    I'm having a problem accessing an external table in an Oracle 10g and Windows 2003 server environment. The disk is remote (mapped) to the server. It's the usual access errors, kup-04001 or kup-04063.
    I have the [seemingly] exact same setup in an Oracle 9i and Windows 2000 server environment which works perfectly. Services run as local SYSTEM and SYSTEM has full permissions on the disk. Directories exist and so do the permissions to the directories.
    In the Oracle 10g and Windows 2003 environment, services run as local SYSTEM and SYSTEM has full permissions on the mapped disk. Directories exist and so do the permissions to the directories.
    This obviously effects mappings, deployments, etc.
    Does anyone know if something changed in either the db or the os?
    Thank you,
    Michael

    Thank you for your reply.
    Your proposal is the standard solution. As a matter of fact, that's how it is on my "old" system. Server "A" Oracle services are started by SYSTEM. Server "B" Oracle services are started by SYSTEM and is where the flat files reside. SYSTEM has full permissions on a disk local to Server "B". Database directoriies defined on Server "A" point to Server "B" remote disk. External Tables on Server "A" are defined with directories that point to Server "B" remote (mapped) disk. I have no problems with this configuration.
    I'm having a problem acheiving the same configuration with Oracle 10g and Windows 2003. I guess I'm baffled over the fact it isn't working the same way as my "old" environment. Why shouldn't it? Oracle (and you) want me to start services as a specific user. It shouldn't have to be that way unless something changed in the way the database makes calls to the os or if Microsoft slipped something in with one of it's numerous security patches.

    mmmh. Did you compared the select count(*) from your_table; in the two cases.
    If the result is not good and nobody has deleted rows between migration and your test, you migration need to be replayed.
    Which migration did you select, Transportable database or exp/imp...?

  • Oracle 10G and SGA

    Hi,
    i've a question about Oracle 10G and their SGA. When I do in SQLplus show sga, I get for example:
    SQL> show sga
    Total System Global Area 167772160 bytes
    Fixed Size 1247900 bytes
    Variable Size 58721636 bytes
    Database Buffers 104857600 bytes
    Redo Buffers 2945024 bytes
    when finding other parameter I get always '0', this was not in other releases...
    SQL> show parameter pool
    shared_pool_size big integer 0
    java_pool_size big integer 0
    large_pool_size big integer 0
    olap_page_pool_size big integer 0
    SQL> show parameter db_cache
    NAME TYPE VALUE
    db_cache_advice string ON
    db_cache_size big integer 0
    It seems that I have no control over setting those parameters, I remember at installation time it gave a % of the pc memory would be used, has it something to do with that? Can you chose between the automatic SGA-management and setting it by yourself?
    thanks

    Server "A" Oracle services are started by SYSTEM. Server "B" Oracle services are started by SYSTEM and is where the flat files reside. SYSTEM has full permissions on a disk local to Server "B". Database directoriies defined on Server "A" point to Server "B" remote disk. External Tables on Server "A" are defined with directories that point to Server "B" remote (mapped) disk.

    Typeically if 10g is installed in /home/roacle/product/10.2.0, are you saying that for 11g, it would be /home/oracle/product/11.0.0 ?
    How about switching the application? Does changing the ORACLE_HOME and PATH environment variable setting enough ? Let's say from
