How can I know the size of DB Table

Hi, Guys,
1. How can I know the size of the DB Table in terms of kb
2. If I delete some records from the Table, does the actual size of the Table remains  same or will it be reduced.
3. If size remains same after deletion, how to reduce the size ( i.e. occupied space).
thanks
Mahesh

Hi
1. How can I know the size of the DB Table in terms of kb
There is no precise method/tcode/program to know the Table size of a tables.
Just based on the record size of a table(say for example 2kb), and if 200 records are there then, we roughly assume that it occupied 400 kb.
All the tables are stored in Table spaces.
2. If I delete some records from the Table, does the actual size of the Table remains same or will it be reduced.
Time being it remains same. it won't get reduced immediately
during some next DB reorganisation it gets reorganised by reducing it.
3. If size remains same after deletion, how to reduce the size ( i.e. occupied space).
during next DB reorganisation it gets reorganised by reducing it.
Reward points if useful

  • How can we know the size of the dimension(in Line item Dim)?

    Hi to all experts,
    We use Line item dimension if the size of dimension is 20% or more of the fact table. My doubt is that how can v know that the size of the dimesion is 20% or more of FT?. But we never store MD in dimension tables......So please help me to understand this scenario? Thanks in advance.

    Hi
    Normally before modelling you will assume the number of entries in your master data and transactional data..
    If your dimension is having 3 characteristics
    say A,B .....and these characteristic values are say
    A---10,000( Total number of master data records)
    B----7,000( Total number of master data records)
    then your dimenstion would be 10,000 * 7,000 =700000000
    in this case you better keep A in a dimension and B in another dimension.
    Normally SAP recommends your dimension table shouldnot exceed 100,000...
    so whenever you expect a characteristic is having more values then you should make it as line item...
    If you want to add a new characteristic to the existing model then you can decide by comparing the ratio of dimension table to the fact table..
    Please have a look at the below url for sizes
    dimension size
    Hope it helps

  • How can I know the size of a JViewport laid out in BorderLayout.CENTER?

    I have a JPanel inside a JScrollPane. The scroll pane is laid out inside of BorderLayout.CENTER. I need to know the size of the JViewport to do stuff like centering and zooming.
    Where can I find the size? All these methods return 0 values for X and Y:
    myScrollPane.getViewport().getSize()
    myScrollPane().getSize()
    myScrollPane.getHorizontalScrollbar().getValue()
    Yes, even the scrollbars won't give me any values! It's all because of the BorderLayout!
    Any ideas? Thanks.

    Sounds like you are accessing the sizes before the views are realized (that is before a call to frame.pack()/show()) They are available only after the layoutManager had a go on it. What is available earlier are preferred/min/max, though.

    Hi
    You can the Meta Data for the result set and then get the getColumnCount() from the MataData to get the number of columns in the resultset.

  • How can I view the size of a particular event in iPhoto '11?

    How can I view the size of a particular event in iPhoto '11? The 'Get Info' option is not displaying the size of the event like it used to in iPhoto 8.

    But the event does not really have a size - you can export the photos and make the size pretty much what you want - while it is in iPhoto it is an event
    I guess that iPhoto could report the size of the original photos as imported - or the size of the modified photos if exported as JPEGs - or the size of the modified photos if exported with a maximum dimension of 1080 - but the event simply is photos and does not have a "size" until you export it
    Obviously you want to know the size but the question was
    what is your puprose for knowing the size?
    WIth that information maybe there is a way to get you what you want
    But the basic answer is simply that an event does not have a size - an event is a collection of photos and each photo has either two or three versions in the iPhoto library and each photo can be exported for outside use in several formats and at any size

    I have an imac 27 inch O SX 10.6.8. using iphoto 11 Version 9.1.5. I have scanned some photos at very high resolution with each photo being about 45MB. They're saved to desktop. How can I reduce the size of the scanned photo's they are crashing iphoto.

    What format are they? Tiif? Jpeg? You can compress them with a lot of apps - including Preivew and just about any graphics editor out there. I'm not sure that 45mb would crash iPhoto thogh, are yo sure that's the cause? I know that some folks have mentioned pixel dimensions causing issues, as can color profiles.

  • How can i know the number of lines in field-symbol internal table

    how can i know the number of lines in field-symbol internal table

    Hi,
    If your field symbol has been defined as an internal table :
    Use std describe as
    Data: l type i.
    describe <fs> lines l.
    'l' will contain the number of lines as needed.
    FYI
    The size of this storage area in a field symbols depends on the number of table lines which is not fixed, but determined dynamically at runtime.

    Can I expect the function of data compression in HANA ?
    Thanks in advance .

    Please take attetion:
    Your linux box already created = Application server:

    Based on the measurements SAP doesn't expect any changes concerning CPU, memory and network requirements for the ABAP application server. This means that the existing hardware and network infrastructure can still be used. Please check the PAM (www.service.sap.com/pam) for further details.

  • How can I reduce the size of the jvm?

    I would like to decrease the size of a jvm; I've found a program that makes it, but you don't know how does it works (and you have to pay for it), I'm talking about VM Optimizer 2.0, from Invirtus.
    Can anyone tell me how can I reduce the size of the jvm?
    Thanks a lot.

    I assume you mean the size of a JVM instance in memory and not the size of the JRE which is on the disk.
    I don't believe that there is any way at present for your Java code to change the amount of memory available to the JVM. This shouldn't matter too much, though. Firstly, you can control the size of the JVM from the command prompt with the -Xms and -Xmx options. Secondly, any remotely reasonable operating system is going to wait until the JVM has requested memory before allocating all of it. If you start a JVM with a 2Gb heap, it does not occupy 2Gb of physical memory straight away.
    Finally, I did a Google on InVirtus VM Optimizer and must request some information. What does that software have to do with Java? It's designed to reduce the size of a virtual computer as created by a prorgam such as VMWare. It has nothing to do with the Java virtual machine.

  • How can we know that size of dimension is more than fact table?

    how can we know that size of dimension is more than fact table?
    this was the question asked for me in interview

    Hi Reddy,
      This is common way finding the size of cube or dimensions or KF.
    Each keyfiure occupies 10 Bytes of memory
    Each Char occupies 6 Bytes of memory
    So in an Infocube the maximum number of fields are 256 out of which 233 keyfigure, 16 Dimesions and 6 special char.
    So The maximum capacity of a cube
    = 233(Key figure)10 + 16(Characteristics)6 + 6(Sp.Char)*6
    In general InfoCube size should not exceed 100 GB of data
    Hope it answer your question.

  • How can I change the size of the FINDER bar so that I can make it easier to read on the 27 inch monitor.

    How can I change the size of the FINDER toolbar so that its eaier to read i.e. make the text bigger.
    How can you move the orientaion of the left side menus so that they sit above a document when using word. If you have a single document open you tend to place it in the centre of the screen and the drop down menus are so far away.

    I don't know of a way to change the size of the menu bar.
    For the other, take a look at Menu Pop. I don't know anything about it. Just happened across it the other day.

  • Is there a limit for the apps that i purchased or i can purchase as much i want? and how can i know the capacity it's taking? Thank you

    Is there a limit for the apps that i purchased or i can purchase as much i want? and how can i know the capacity it's taking? Thank you

    Yes you can buy whatever you want if your credit card is in good standing.
    Before you buy, read the size of the download in iTunes/App/iBook Store.
    Rule of thumb, you need to reserve about 10% of your total space.
