How to calculate the size of index?

How to calculate the size of indexes for a small relational database. Please make it clear that I understand.

Hello

How to measure size.

View DBA_SEGMENTS gives the size of all the Segments (Table, Index,...).

If you can for example use a query like this:

select segment_name, bytes "Size in Bytes"
from dba_segments
where owner = ''
and segment_name = ''
and segment_type = 'INDEX'

Hope this helps.
Best regards

    How to calculate the size of the HFM Cube in SQL Server2005

    Under application used to Oracle. So what's application to SQL Server?

    ***********************************************************************************************************

    **********************************************************************************************************

    Concerning
    Smilee

    What is your goal? The subcube in HFM is a concept that applies to application layer - not so much to the database layer. The size of the subcube is the unique number of sheets (data values for January - December inclusive, for example) for the given entity, a triplet of currency or node Parent.Child. Should be considered for accounts of parent and customs that do not exist in the database, but are calculated in the RAM of the application layer.

    So if your goal is to find the largest subcubes, you could do this by querying the database and by counting the number of records per entity value (tables DCE) or combination of entity parent.child (tables of the DCN). I am not versed in SQL, but I think the script below you would just the size of the pattern and not the sizes of subcube.

    See Accelatis.com for a third party software product that can do it for you. The function is called the subcube Analyzer and was written by the same team that wrote HFM, then they should know how :-)

  • How to calculate the size of a VMFS volume?

    Creating a new partitiontable after ESXi 4 wiped empty was pretty easy with fdisk.
    These days with partedUtil and ESXi 5 is not so trivial.

    Consider that we have a disk/Lun, which looks like this

    ~ # partedUtil get /vmfs/devices/disks/mpx.vmhba1:C0:T4:L0
    93990 255 63 1509949440

    and suggests that the original - now messed the Volume was created with ESXi 5.
    How to calculate the value of the end in the sector so that I can recreate the VMFS partition like this:

    partedUtil setptbl ' / vmfs/devices/disks/mpx.vmhba1:C0:T4:L0 ' TPG '1-2048 ? '. AA31E02A400F11DB9590000C2911D1B8 0 "


    In this case, the correct value is 1509949349, but how do I calculate if I don't know the correct value?

    Hello

    the output of the command "partedUtil get /vmfs/devices/disks/mpx.vmhba1:C0:T4:L0" will be useful in your case, it's "93990 255 63 1509949440".

    gives us the values for C/H/S (cylinder/head/sector).

    A VMFS volume partition must end on the limit of a cylinder, so selecting the last sector of the partition table should be done using the formula endSector = (C * H * S - 1).

    who is '1509949440-1' = 1509949349.

  • Calculate the size of fonts depends on each device

    Hello everyone

    Anyone know how to calculate the size of font suitable for each device? the 8100 and 8300 look fine but to 8900 look small the same font size (18px), so I'm looking for something, a setting to help me calculate control font size.

    the screen resolution is a possible cause, how do you know this and use it for this proposal?

  • How to find the sizes of all schema objects

    Hi guru,.

    I have a 10.2.0.4 database on the Windows platform.

    How can I calculate the size of a particular schema objects (i.e.table, index, Mviews etc.)?

    Is any dynamic script available for the same thing?


    Thanks in advance.

    Why do you want to include nom_segment in the State? You need size of all objects in the schema.
    simply question query provided that WHEN the OWNER = "tbl";
    If you need that in Excel, you can use SQL Developer or any available for Oracle GUI tools.

  • How Illustrator calculates the height of box Em?

    I am trying to determine how Illustrator calculates the basic position of the top of the a Point text object bounding box.  She seems to be the same distance as an object of text box with the game setting of first base to box Em height line.  I just do not know what assets within the scope of the police which matches.  Help of the Illustrator defines it as:

    "The top of the box em in Asian fonts touches the top of the type object. This option is available regardless of the preference show Asian Options. »

    For some fonts, this distance seems to be near the pole of the police, but this is not true for each font.  The clues how Illustrator calculates it?

    Here you go

    var idoc = app.activeDocument;
    var itext = idoc.selection[0];
    
    var top = itext.position[1];

  • How to get the size of the binary cache from code

    Is there a way to get the size of the cache in bytes? (size() method retrieves the number of objects, as when the size of the cache is limited in configuration by unit-calculator 'BINARY')?

    Hey Meir,

    As Wei said that there is a JMX exposed for each cache bean and you can just summarize the units attribute. There is a second attribute called UnitFactor that you also use to be precise. In most cases, UnitFactor will be 1 but the appropriate calculation of size in bytes of a cache is

    Units * UnitFactor

    Second, you ask this cache across all members of storage and summarize the results. This will give you then the size that includes the key and value but not take account of all sizes to index.

    An easy way to make JMX requests within the coherence is:

    String cacheName = "";
    MBeanServer mbs = MBeanHelper.findMBeanServer();
    Set names = mbsc.queryNames(new ObjectName("Coherence:type=Cache,service=*,name=" + cacheName + ",*"), null);
    
    long totalUnits = 0;
    for (ObjectName name : names) {
        Integer units = (Integer) mbs.getAttribute(name, "Units");
        Integer unitFactor = (Integer) mbs.getAttribute(name, "UnitFactor");
        totalUnits += (units * unitFactor);
    }
    System.out.println("Total Units = " + totalUnits);
    

    There are other ways to get the size too.
    You could write an aggregator that calls BinaryMemoryCalculator.INSTANCE.calculateUnits with the binary key and the value of each entry that went. This would not be very effective, but would be useful if you want to calculate the size of a subset filtered registration.
    You could write a remained that gets the support of the cache card you want, cast to LocalCache and then call the appropriate methods to get unitfactor and units. You must run this invoked on each Member of storage.

    The code expects milliseconds, then 26 seconds would be written as
    this:

    26000

    If he said 01:22 (one minute and 22 seconds), you must write it like this:

    82000

    ... which is 60 seconds for now, 22 seconds
    side, then multiplied by 1,000 to get milliseconds.

  • How to reduce the size of the records Quicktime file?

    On my Mac, they take as much space as 1 GB for a film record or a screen for 2 minutes.

    I don't see that you can export out of other than QT. MOV

    but you can use an external converter

    While it is mainly used to convert video files to DVD it will also convert video files.

    Thank you and best regards,

    Hello r,.

    A SCTL will always run in a beat the clock it has been linked to.  So, if you use a 40 MHz clock, this loop will run in 25 ns.  If the code cannot complete in that, or if it requires two graduations of the watch to do the calculation, your code does not compile, then you have the guarantee that this will always be how long it takes this piece of code to run.
