How to estimate the database size?

Hello. I have a database model in SQL data modeler. Also I've created it on the test server, but it is empty now.
Now I need to estimate the size of the database for understanding the requirements to production hardware.
For, example how many gigabytes I need in two years for my database. How can I do it?
Thank you in advance.

It is called "volumetrics" in ErWIN.

    Hi Kasi,
    Your question is not very clear, from the looks of it, the load on your client's system will be doubling soon.
    You need to look at the system stats on how the system is handling the current load, use transactions ST06, ST04 and ST02 to check if the DB hit ratios are as expected, the cpu idle time, the busy periods. Identify if there is large amounts of paging on the server(candidate for increase in real memory).
    On AIX level, you will need to look at CPU / Memory usage.
    On SAP Application server, you need to look at SAP Buffers.
    On Oracle end, look at SGA stats, if it need to increase, the data growth that is current and estimated growth (DB02).
    You will not get an exact answer to it, you will need to analyze the existing load and then estimate (guess). The hardware upgrade will also depend on what the client is willing to spend, its always a good practise to add 20% to what you have estimated as these figures are never accurate.
    All the best.

  • How to know the database size

    can one tell how to find the database size?

    Depends what you mean by database size and how you want the output to look?
    Are you referring to the number of rows across all tables of a schema? The number of bytes used by the rows? The number of bytes used by the tablespaces? The number of bytes used by the datafiles? etc. etc. etc. So many options.
    Be more clear in your requirements please.

  • How to reduce the database size based on MS SQL/Oracle?

    Hi,
    I had deleted severy clients via SCC5, but the database size is more and more bigger. Do you know how to reduce the database size.
    my platform is: NT, MS SQL 2005

    Hi Simon,
    In the case of SQL you need to check how many space free you have in your datafiles and the based on that you need to Shrink them using DBCC SHRINKFILE command.
    Find a couple of reference docs here,
    http://www.intermedia.net/support/kb/default.asp?id=996
    http://doc.ddart.net/mssql/sql70/dbcc_21.htm
    Also i'm pretty sure that if your check the properties of the datafiles in MSSQL Enterprise Manager you get a "Shrink" option.

  • How to get the Database size?

    Hai Friends,
    I have created a Z Table with 100 fields. i want to check the database size after uploading the data. How can i do this?. That is, after uploading the first entry i want to know the size and again i want to upload 5 more entries and to check the growth.
    Where can i see this?. i have checked in DB02 but even after data upload i didnt see the size. kindly explain me the process.
    Thanks..................

    Hi,
    In the Go to Menu then Check the Number of entries to track your current set of entries.
    For DB Size  check Technical Settings . Tab Logical Settings parameters the Data class and Size category can give you how much data the table can hold.
    Thanks,

  • How to get the database size of several system

    Hi
    We've got a lot of database system on our landscape. I want to make a simple report to get the size the all our database on a weekly base.
    I try to get a RZ20 value on it without succes.
    Do you know a sql request that i could launch on all my database to get this information ? i did'nt find any V$^view with this information.
    thanks for your help

    "The database size" can be
    - the total size
    - the filled size
    - the filled size without undo/temp
    You can use DBACOCKPIT to centrally manage multiple instance and check the sizes.

  • How to reduce the database size after deleting huge amount of rows?

    Hi,
    I have a large database. I removed almost half of the data/rows. Now i need to reduce the size of the database file as I need more disk space for the database file.
    What should I do in details please.

    Thanks.
    Deleting large data would have ultimately put ghost cleanup into action. You would not be able to free space using shrink operation untill it completes. So wait for time and then start shrinking. You should note that shrinking would cause fragmentation and
    you would have to rebuild indexes after shrinking is completed

  • Estimating the Database Size using Archivelog mode

    Dear OTN Forum,
    I need to find guidelines to estimate the additional space needed for a database in order to operate in archivelog mode.
    I've estimated the size of a database (Tables + indexes= 450 GB + 270 GB) operating in nonarchivelog mode, but I didn't know how to estimate the additional space needed to operate the database in archivelog mode.
    Please any kind of information will be well received!
    (paper, technical bulletins, metalink, etc.)
    Best regards,
    Alfredo

    The space required for archive logs does not depend on the size of your database. It is dependent on 3 factors.
    1. The size of your redo log members. Each archive log will be the same size as a redo log file.
    2. The number of transactions you do in the database. Each transaction writes information to the redo logs, and each redo log is archived when it is full.
    3. How laong a period you want to keep the archive logs available on disk for.
    For example, one of our systems is a very active OLTP system with about 500 users at peak times and around 100 fairly constantly. The database is about 40Gb, but it spins 15 - 20 64Mb archive logs each day. Typically, we keep 2 days worth of logs on-line at any given time. so, this system requires between 1.8 and 2.5 GB for archive logs.
    Another system, used mostly for reporting purposes, is over 100GB, but typically generates 5 - 6 32MB archive logs each week. So, it requires less than 200Mb for archive logs.

  • How to estimate undo tablespace size in 11g?

    I found someone document said, use this sql to estimate undo tablespace:
    select (UR*(UPS*DBS))+(DBS*24) as "bytes" from (select value as UR from v$parameter where name='undo_retention'),(select (sum(undoblks)/sum(((end_time-begin_time)*86400))) as UPS from v$undostat),(select value as DBS from v$parameter where name='db_block_size');
    but in my 11g database, the "select value as UR from v$parameter where name='undo_retention'" is 0. so above sql is always get 196608(8192*24)
    How to estimate undo tablespace size in 11g?
    Thanks very much!

    for undo segments size you should turn it to be autoextend on as well undo management set to be AUTO
    i.e
    undo_managment='AUTO'
    for retention see that link
    Ora-01555, snapshot too old: rollback segment number 2 with name "_SYSSMU1
    BTW as hemant stated leave it to be auto which is good approach but make sure enough space on disk has been
    dedicated for undo segments are allowed to grow to the size they need to be based on the requested undo_retention.

    Hi,
    how can i estimate oracle database size before building up. is there any query or formula there to estimate the size.
    i read a thread of Sir. Joel Pérez if he is available then i m requesting him to send me that docs that you are posted for the estimation query.

    Use the DBMS_SPACE built-in package to estimate table and index cost (size).

  • How to recover the database when some of the archive log file get deleted.

    Hi,
    Archive log files are the copies of redolog files.As redo log files are circularly overwritten,oracle generates archive log file of the corresponding redo logfiles being overwritten.So if you have a backup that dates back to 10 am in the morning and if your database creashed at 3 pm,you cannot use the redo log files alone as they have incomplete information.To completely recover the database upto 3 pm,you need archive log files generated between 10 am to 3 pm. In your case since you are missing one archive log file,you cannot perform complete recovery and hence would suffer data loss.

  • Best Trategy to reduce the Database Size

    Hi Everyone,
    In our Client's Landscape SAP systems have been upgraded to newer versions whereas our client want
    one copy of older Production systems (one copy to retain)
    1) SAP R/3 4.6 C system  (database size of this system is approx 2TB)
    2) SAP BW 3.0 (database size of this system is approx 2TB)
    Now CLient wants us to reduce the database size via re-organization because Archiving of IDOCs & Links we have already done
    Client has recommended for :
    1) Oracle Export/Import: Only Oracle DBA can do (ignore this one)
    2) Database Reorganization : We have tried Reoragnization via BRtools but found very tedious 9 (ignore this one)
    3) SAP Export/Import : Via this way we want to reduce the database size
    Can anybody Tell us How much Free space do we require in order at OS level in order to store the Database Export
    of Two Databases of size around 4TB & what would be the best strategy of reducing the Dabase size.
    Via SAP Export/Import how much approx how much database size will be reduced
    Thanks & Regards
    Deepak Gosain

    Hi,
    >Can anybody Tell us How much Free space do we require in order at OS level in order to store the Database Export
    >of Two Databases of size around 4TB & what would be the best strategy of reducing the Dabase size.
    The only realistic way to know is to do a system copy of the production system on a testbed system and to test the Database Export.
    If you really want to decrease the database size you will have to archive a lot more than the IDOC archiving object.

  • How to modify the blob size, or how to set the size?

    i want to know how to modify the blob size, or how to set the size?
    what's the default size of blob?
    Thanks in advance.

    Blob datatype can contain binary data with a maximum size of 4 GB.
    when you enter 10kb file, the database will only use 10kb to store the file (depending on block size etc)
    if you want to modify the blob size, you may do like this:
    SQL> create materialized view t_mv refresh fast on commit
    2 as select id, dbms_lob.getlength(x) len from t;
    Materialized view created.
    SQL> alter table t_mv add constraint t_mv_chk check (len < 100);
    Table altered.
