How an index increase ?

Hi
I have Oracle 10.2.0.4
I have a doubt regarding how the index increases
I have followign information, the index is from the table in the following information:
SEGMENT_TYPE     18-Feb     19-Feb     22-Feb     23-Feb     24-Feb     "% Increase
INDEX     64.00     64.00     64.00     64.00     72.00     11.11
SEGMENT_TYPE     18-Feb     19-Feb     22-Feb     23-Feb     24-Feb     "% Increase
TABLE     424.00     424.00     424.00     424.00     424.00     0.00
My question is: Why the index has increased but the table did not has any increase?
thank you in advance

thank you in advanceYou're looking at the space reserved for the table and index, not the space actually used.
Some time between the 23rd and 24th the index needed one more block after using the current 64, and 8 was the next allocation reserved for it.
It's quite possible that the table was using 300 out of 424 blocks on 18th, and has been using 20 more blocks each day since - and hasn't got to the end of its current reserve.

    The fields in the INDEX of the Table EKPO should be in the same sequence as in the WHERE clasuse?

    Hi,
    You minimize the size of the result set by using the WHERE and HAVING clauses. To increase the efficiency of these clauses, you should formulate them to fit with the database table indexes.
    Database Indexes
    Indexes speed up data selection from the database. They consist of selected fields of a table, of which a copy is then made in sorted order. If you specify the index fields correctly in a condition in the WHERE or HAVING clause, the system only searches part of the index (index range scan).
    The primary index is always created automatically in the R/3 System. It consists of the primary key fields of the database table. This means that for each combination of fields in the index, there is a maximum of one line in the table. This kind of index is also known as UNIQUE. If you cannot use the primary index to determine the result set because, for example, none of the primary index fields occur in the WHERE or HAVING clause, the system searches through the entire table (full table scan). For this case, you can create secondary indexes, which can restrict the number of table entries searched to form the result set.

  • How does Index fragmentation and statistics affect the sql query performance

    Hi,

    How does Index fragmentation and statistics affect the sql query performance
    Very simple answer, outdated statistics will lead optimizer to create bad plans which in turn will require more resources and this will impact performance. If index is fragmented ( mainly clustered index,holds true for Non clustred as well) time spent in finding
    the value will be more as query would have to search fragmented index to look for data, additional spaces will increase search time.

  • How should i increase over all buffer hit ratio.....

    Hi all,
    As shown below if my DB2 databse buffer Qulaity is low .. How should i increase over all buffer hit ratio..
    Please advice on any sap standrd notes or procedures
    Number                                    1
    Total Size                           80,000  KB
    Physical Reads                         6.65  ms
    Physical Writes                        0.00  ms
    Overall Buffer Quality                86.05  %
    Data Hit Ratio                        85.79  %
    Index Hit Ratio                       87.50  %
    No Victim Buffers                259,079,295
    --rahul

    One of the options is to simply increase the bufferpool size using the following command
    db2 alter bufferpool immediate <bufferpool name> size <new bufferpool size>
    However, this will affect the hit ration for a particular bufferpool. If you have more than one bufferpool, you need to identify the bufferpool(s) with worst hit ratio. In the SAP DBA Cockpit, check using
    Performance -> Bufferpool
    The victim buffer information is only useful in case you use alternate page cleaning.
    Note that there are other options to fight bad bufferpool hit ratio - however, with your small bufferpool size (80MB) maybe increasing the size is the appropriate step.

    Do I have to configure anything in Biztalk adapters or SQL agent?
    Christiane

    In BizTalk:
    You can increase the BizTalk performance by adding multiple instance of host . i.e. add more instance of the host instance which are configured to the send port. So you will more instances
    to process your messages concurrently, this would increase the throughput.
    Try to use batch imports rather than record level imports.
    Always type your stored procedure parameter(s) as NVARCHAR(MAX) when sending an XML message to SQL Server.
    Avoid dynamic ports with the WCF adapters, and in particular the WCF SQL adapter, in favor of static ports with a dynamic Action

    On 11in Macbook Air (10.10), how do I increase resolution of built-in display to 2560 by 1600 pixels?
    It can be accomplished when an external display is connected, so I expect it can be done without an external display.

    You're getting full native resolution 1366 x 768 on your internal display, nothing more.

    I use iwires to connect macbook to lg tv to watch netflix.How do you increase screen size on rv.I have tried display settings ,but not working

    I would guess that the HDMI port on your mac is for output only - no input, and that's what your'e attempting to do when you attach the mac to your xbox. I looked in Mactracker and it lists the HDMI port as video output for both the 13" Retina MacBook Pro and the 15" Retina MacBook Pro (your post didn't say which one you have), so looks like that is the issue..

  • My performance is very slow when I run graphs. How do I increase the speed at which I can do other things while the data is being updated and displayed on the graphs?

    I am doing an an aquisition and displaying the data on graphs. When I run the program it is slow. I think because I have the number of scans to read associated with my scan rate. It takes the number of seconds I want to display on the chart times the scan rate and feeds that into the number of samples to read at a time from the AI read. The problem is that it stalls until the data points are aquired and displayed so I cannot click or change values on the front panel until the updates occur on the graph. What can I do to be able to help this?

  • How do I increase the font size in my email and maintain resolution.

    Hi folks. Mr Newbie is seeking some help, I hope it is relatively straight forward, thanks
    How do I increase the font size in my standard email and document views without losing resolution.  Right now my font size in email, headers and text is less than that on my iPhone, it rather defeats the point of having a 27" screen if most of it is blank and I have to sit with my nose to the screen to read email.  Thanks for your help, once you have stopped laughing.  C

    Two things you can do to easily aid with readability in Mail are as follows:
    1) Increase the size of folders in the sidebar:
    a) select "system preferences" from the Apple menu
    b) select "general settings"
    c) select small, medium or large under "sidebar icon size"
    2) Increase the text in the main body of the email (both sent and received):
    a) select "preferences" from the Mail menu
    b) select "fonts and colors"
    c) adjust font size for "message list font" and "message font".  I have noticed this works properly while in classic mode, but in regular mode the message list font doesn't appear to change size.
    Select classic mode by accessing Mail preferences and selecting the "viewing" tab.
    Another shortcut is to right click on the toolbar, then select "customize toolbar", and then drag the "smaller / bigger" buttons onto the toolbar.  Now you can decrease and increase font size as desired on the fly.
