Will the database size be increased ?

HI All,
I like to ask, will the datafile size be increase, if we put our tablespace in backup mode and forget to put in back in end backup mode.
According to me not, because all the transaction activity will be carried out into redologs and of course, there will be significant increase in redologs. Please correct me, If I am wrong.

The size of datafile itself will not be affected, but as you mentioned, the amount of redo that you generate will increase.

How to increase the database size

Hi All ,
Our Client is going to increase their customers from 3.5 million to 5 millions
(12 millions in future ) and there is no increase in the existing licenses..
At present we have very less space in Data base server. We are Going Live at the End of the Month.
How to increase the database size to meet the Client requirements.
we have to increase the No of Processerors etc...
Below are the details of Servers:
System Model: IBM,7040-681
Machine Serial Number: 830D5BF
Processor Type: PowerPC_POWER4
Number Of Processors: 2

Note : Server is IBM P690.
1) System Lansdcape --> Two System Landsacpe ( Dev to Prod )
2) BW Version --> 3.5
3) SAP Basis --- > 6.4
4) No of Application servers currently having --> Only One Server
Can any body suggest me how to solve this.....
Thanks in Advance..

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.

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.

Calculate the database size for a particular company code in SAP

Hi Experts,
We have 30 company codes in our FI production system. So to plan another new company code to be deployed into the system, we need to know exact data capacity (database) of the previous company code that we already deployed. Kindly let me know whether it possible to calculate the database size occupied for a particular company code in a SAP system.

Its not possible to calculate data size based on company code.
By creating company code It will not occupy much space. Depends on your posting documents for particular company codes.

Rebuild Database did not reduce the database size

I just completed a rebuild database. The rebuild completed much quicker than anticipated and in the end the did not reduce in size.
This is my first rebuild and since original installation I have deleted a number of masters. From my understanding thumbnails and previews are not deleted when the master is deleted. In order to delete the thumbnails and previews the db must be rebuilt. Is this correct?
The db is over 31.1gb. The rebuild took approx 10 minutes and when completed the db size was still 31.1gb. There was a message during the rebuild that read "Recovering projects". I was expecting to see stats showing previews and thumbnails being generated in the activity window but don't see it. Has the db been rebuilt?
Thanks for any assistance.

Rebuilding the database is for disaster-recovery, not file maintenance. I certainly wouldn't do it unless something was fundamentally broken and the application didn't run.
"rebuilding" the database seems to do the following:
(1) remove the database file completely (not even to the trash, it destroys the database utterly)
(2) run through the plist files and reconstruct a brand-new database from them all
I checked this (on an empty library) using hard-links from the commandline, and step (1) above scared me sufficiently that I'd only rebuild the database as an absolute last resort.
Now, 31GB seems a lot for a database that only took 10 minutes to rebuild - are you sure you're not telling us the size of the library (to find the database size, right-click on the library and select view-package-contents, then open the 'Aperture.aplib' folder and find the size of the 'Library.apdb' file. That's the file you're changing when you 'rebuild database'.)
If you're telling us the size of the entire aperture library instead, then that size will be completely dominated by the master RAW files you've imported. I'd guess your library will be less than 10MB.
My understanding is that previews are deleted (since they're stored as separate files alongside the master image, if you look in the folder hierarchy), but thumbnails aren't. The thumbnails are aggregated together into one-file-per-project (presumably for speed of access), and I'd guess the space is reclaimed for future use, but the file doesn't get any smaller. That's a classic trade-off for speed-of-access, and users like us are normally very keen on things being fast

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 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
NT, Oracle 10.2
Best Regards,
Simon Shen

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,
Anita

Should We consider Temp Data Files While Estimating The Database Size

Hi,
The Database Size is sum of physical files like
Control file
redo log file
datafiles
temp files
so i want to know why are we considering the temp files..Because it's temporary. At one stage of database, temp size it could me more and at one stage it could be less.
So why consider the temp file???
Please share your views on it..
Thanks
Umesh

So, in essence the size of your datafiles is the size of your tablespaces?No. The size of the tablespace is the sum of the sizes of the datafiles in the tablespace --- i.e. the datafiles determine the tablespace size, not the other way round.
(Although when you CREATE or ALTER TABLESPACE, you specify the sizes of the datafiles that you want to belong to the tablespace).
the temporary tablespace has space allocated to it regardless of whether there are temporary tables in that tablespace or not.Two points here :
1. On most OSs the temporary tablespace tempfile is created as a "sparse" file. So, if you issue a CREATE TEMPORARY TABLESPACE TEMP TEMPFILE 'xyz.dbf' SIZE 1000M; and then did an "ls -l" at the OS level, "xyz.dbf' would appear to be only a few tens of KBs in size. The OS "grows" the file to 1000M as necessary.
When talking to your OS administrator ensure that you get 1000M (or the AUTOEXTEND MAXSIZE !!) space allocated even though he might "see" only a few 10s of KBs used on the first day.
2. The temporary tablespace does not have objects (other than "global temporary tables" that overflow from memory to disk). It is really temporary space for joins, sorts, order bys etc.
So, your datafile size is not affected regardless of your temporary tables coming and going.Yes, your datafile sizes and tempfile sizes are independent. Yet, when "sizing" disk space for the database you must include the tempfile size. However, when reporting to IT Management with a statement "our database size is ".. you might want to break it up into components like Data Dictionary, Tables, Indexes, TemporarySpace, RedoLogs and ArchiveLogs. You could also differentiate between OS-allocated space (sizes of datafiles) and Oracle-allocated space (sizes of segments) and actual used space (which you'd have to compute !) .

Email-to facilitate emailing a photo by gmail or AOL, I reduce the file size. Is it better to reduce the image size or increase the jpg compression?

To facilitate emailing a photo by gmail or AOL and avoid overwhelming the recipient's screen, I reduce the file size. Is it better to reduce the image size or increase the jpg compression? I have been making a duplicate image of 35 MB and reducing the image size to 8"x12" at 72 resolution giving a file size of 1.4 MB. Then I SAVE AS a jpg of medium compression giving a file size of about 111 KB. Overkill?

Go to File>save for web.
I usually make the long side 800 px
At the bottom of the dialog, check "constrain proportions."
At the top, select JPEG in the dropdown for the file format.
All the work is done for you! 72px/in is ok for web work. 240-300px/in is the recommended range for printing.

UCCE 10.0 EDMT will reduce database size ?

Hi
We are doing Tech Ref. upgrading CCE 8.0.3 server to CCE 10.0,
Intial HDS DB size is 145GB
after patch upgrade to 8.5, the HDS DB size is 125 GB,
but after EDMT to ver 10.0 the migrated data is 79GB
does something happened in migration towards the new version discarding some data
In EDMT logs everything successfull
In the 8.5 HDS Tables i can see the count is 366 items and for View folder is 443 Items
In the 10.0 HDS tables i can see the count is 343 items and for View folder is 456 Items
Why we see this difference, is it normal, how we got this much reduction in size
Also, there is difference in HDS size between AW A and B too
Thanks

Hello Kanan,
I have installed a Solution Manager 7.1 SP03 system, and I installed using Oracle not max DB.
Right now the system is pretty pristine. The Database allocation is 146GB and of that allocate space I have used about 100GB
My data base size is 146, I do not have a shortage of disk space, and the DB will autoextend should I fill it up.
So my question would be of the 136GB what percentage is used? When you say it is growing, is it extending, or is it just
using more of the allocated space?
I am just now looking at a colleagues Solman 7.1 SP03 system. They have 176GB allocated to the database, but they have 104GB used. Their system has had a fair bit of use, but it is not a production system either, so it doesn't have a real world load on it.
So typically reducing the size of the database, would entail unload the database to a flat file, resizing the database, and then reloading the database. Typically this si a DBA function.
So I am not sure at what point a MaxDB databse would extend if you mean the physical size of the database is getting bigger. Still 136GB wouldn't be considered an unreasonable allocation as my system has 146Gb allocsated to the DB and my Colleague has
176 GB allocated. ButI only used 100GB and they have used many scenarios and has maybe 20 users and only has used 4 GB more than me. So what is the size of the used space verus the allocation?
You can remove various service sessions using report RDSMOPREDUCEDATA, but on a training system, I am not sure how much space that would free up. You can run a DB02 to see the allocation versus what is used, if you are not sure if 136Gb is the allocation or what space has been used. !f 136GB is the allocation, its actually low, and I suspect it is, since MaxDB tends to have a smaller foot print than Oracle. But if it is the space used and not the total allocation, then it seems very high for a training system..
Hope this helps some.
Regards,
Paul

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 find out the database-size

Hello,
how can I find out the size of the database.
I created the user as below. I defined the size of the database to 2MB. Now I want to know how much is the size of the database.
CREATE USER oemer
IDENTIFIED BY ...
DEFAULT TABLESPACE system
QUOTA 2M ON system;

Actually, since Omer is a veteran poster to the Forms and Reports forums, I doubt that. I think he is making a much more interesting journey: from front-end to back-end.
I'll be a bit more helpful this morning.
Databases are ways of organising disk space to store data. Fundamentally they consist of OS files, data files. The RDBMS handles by grouping them into tablespaces. When we build tables we assign them to a tablespace.
So, the size of the database is the sum of its datafiles. Of course, some tablespaces are used for sorting and holding undo information, so the size of the database for the purposes of persisting data is:
SELECT count(x.tablespace_name) AS total_TS, sum(x.MB) AS total_mb, sum(x.free_mb) AS total_free_mb
FROM   ( SELECT t.tablespace_name, sum(d.bytes)/1048576 AS mb, sum(f.bytes)/1048576 AS free_mb
         FROM   dba_free_space f, dba_data_files d, dba_tablespaces t
         WHERE t.contents = 'PERMANENT'
         AND    d.tablespace_name = t.tablespace_name
         AND    d.file_id = f.file_id
         GROUP BY t.tablespace_name ) x
/The SYSTEM tablespace is special. It is used by Oracle to hold the data dictionary, the definitions of all the objects in the database. It should not be used for storing application objects (it affects the performance, apatrt from anything else). That is why we must not use it as a default tablespace.
