How to find out the size of a database?

I'm not an oracle dba but a report developer. I'd like to find out the size of my database.
Is this possible using simple query?

An oracle database consists of data files, redo log files, control files, temporary files. Whenever you say the size of the database this actually means the summation of these files.
select a.data_size+b.temp_size+c.redo_size+d.controlfile_size "total_size in MB"
from
( select sum(bytes)/1024/1024 data_size from dba_data_files ) a,
( select nvl(sum(bytes),0)/1024/1024 temp_size from dba_temp_files ) b,
( select sum(bytes)/1024/1024 redo_size from sys.v_$log ) c,
( select sum(BLOCK_SIZE*FILE_SIZE_BLKS)/1024/1024 controlfile_size from v$controlfile) d;
here
a is megabytes allocated to ALL datafiles
b is megabytes allocated to ALL TEMP files
c is megabytes allocated to ALL redo-logs
d is megabytes allocated to ALL control files

How to find the size of the master data objects in the BW system?

Hi,
We would like to understand the size of the master data tables overall for a specific source system (Logical name is Ex.ABCD, which supplies all master data to BW). Can you please advise the procedure to find out this?
Is there any table that will allows to see all the master data objects related to specific sources system so that we can find out that table size? Thanks.
For example, we have many Texts, Hier & Attributes.
0COUNTRY_TEXT
0REGION_TEXT
0PERSON_ATTR
0MATERIAL_LPRH_HIER
Advance Thanks.

Hi,
You can find out all the master data tales used in the BW system by
Tcode : SE11
Enter as /BIC/P* for master data tables and press F4 which gives list of master data tables currently used in BW system.
Similarly for Texts /BIC/T* and press F4
Similarly for Hierarchies /BIC/H-* press F4
and can know the size of the all tables.
Thanks,
Gopal

For the life of me, I can't find out what size a photo is in terms of inches or how to change the size of the photo[s] so I can print them. I think I read somewhere to click edit, then click adjust. Nothing there about sizing.

For the life of me, I can't find out what size a photo is in terms of inches or how to change the size of the photo[s] so I can print them. I think I read somewhere to click edit, then click adjust. I don't see anything about re-sizing when I click the adjust tab: only saturation and tint levels. Thank you.

With respect to digital images, there really is no size in inches. The size is given as number of pixels horizontally and vertically. In iPhoto '09 you click the little "i" inthe lower right side of the window and it will display information related to the selected photo, including the pixel dimensions. I do not have iPhoto '11 installed so I don't know if it is the same there.
In some applications, such as preview, it has something additional called Dots per Inch (DPI) which you would think would allow you to convert the pixel dimensions to inches. It is not a real thing, though. The DPI is determined by how large or small you have chosen to print your photo and the capabilities of your printer.
There is also something called Aspect Ratio, which is usually expressed in inches x inches such as 6x9 but that doesn't mean the size on the screen or when printed is 6x9. It is the ratio of the pixel dimensions. When cropping your photos, you will have several standard aspect ratios to choose from plus any custom ones you create.
In iPhoto '09, after you choose Print, in the Print Setting window are the settings for the size you want the photo printed. You want to shoose a setting with the same aspect ratio of your photo. Otherwise, iPhoto will resize and/or crop your photo to fit the size you have chosen.

FREE SPACE : To find the size of the report on INFO VIEW.

Hello,
We have recently started using BO XI R2.Could anybody please let us know how to find the size of reports from INFO VIEW ?
Please find a brief of the situation we are currently encountering
We use the web portal " INFOVIEW PROD " to access all the reports in BO. However, the all these reports are stored on the E drive of a production machine . Now the E drive has reached 80% of its capacity and we need to free some space . We cannot delete files directly from E drive of the machine as it stores reports merely on the basis of numbers .The other option is to delete the unused reports from web portal. However , we are talking about 1000's of reports.Also , from the INFO VIEW we are not able to determine the size of the report to delete based on size and unusability.
We would like some input on how to tackle this issue.
Regards,
BO USER R2

Hello,
Well that's really surprising to see that you have recently started using XIR2 since this is already an end of life product from SAP Business Objects.
Well nevertheless there is an option to check these details.
There is tool known as "Query Builder" in BOE
The direct URL to start this is: - http://<servername>:<port>/AdminTools/querybuilder/ie.jsp
and provide below query: -
select SI_ID, SI_NAME,SI_FILES,SI_SIZE from CI_INFOOBJECTS where SI_KIND='Webi' Order BY SI_SIZE DESC
SI_ID: - ID of the infoobject.
SI_NAME: - name of the object
Under SI_FILES you will get SI_PATH which will tell you the location from IFRS
SI_SIZE: will tell you the size.
But I would like to highlight one thing you need to check the instances of the document as well.
Don't just start deleting everything, it can create more problems with the system.
Take the backup of IFRS, OFRS and CMS DB as well.
My reply is just to tell how you can find the webi document according to size and IFRS path
Thanks,
Vivek

Why the size of the tif file is different in photoshop workspace compare to the Preview in Finder?

1. Why the size of the tif file is different in photoshop's workspace compare to the Preview in Finder?
Please look at the screen captures.
Bottom left panel of Photoshop's workspace.
Finder's Preview.
2. I have an imac with 8gb ram, and assigned 6gb ram to photoshop use. But when I worked on a 24mb tif file, photoshop was lagging. And at the bottom left panel of Photoshop's workspace, the doc size is something/1gb. The tif file is only 24mb, why is it slow in photoshop? I have a lot of ram.
Let me know, please.

Thank you MIchelPM for giving me a very detailed explanation.
So I understood why the photoshop doc size is bigger when working in photoshop.
Regarding to your questions:
1. How full is your Mac's hard drive?
    Not even 30% full, I even have a 1TB backup hard drive connected.
2. How many applications do you run simultaneously in the background while working in another application?
    I usually only have photoshop or illustrator opened. Sometimes I ran 3-4 tif files at the same time, but when a big file (ex. 24mb tif) gets very slow, I closed all other files and programs, and "purged all" in photoshop, yet that 24mb tif file was still slow.
   I checked photoshop's ram and cpu usage in the activity monitor. Rarely photoshop's cpu usage would hit 100. But when I worked with the 24mb tif file, it would used all the ram that I've allocated to photoshop.
But the myth is, my coworker who worked with the same file in CS4 with only 4gb ram in their imac don't have photoshop slowed down, when I have double the ram and CS6.
3. What year, screen size, CPU speed of your Mac?
   I have 27" imac,
   • 2.9GHz 2.9GHz quad-core Intel Core i5 processor (Turbo Boost up to 3.6GHz) with 6MB L3 cache,
   • 1TB (7200-rpm) hard drive
   • NVIDIA GeForce GTX 660M graphics processor with 512MB of GDDR5 memory
4. What version of OS X is your Mac using?
    Mountain Lion with the latest updates.
5. What version of Photoshop are you using?
   • Photoshop CS6

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.

Can change the size of the redolog files while the database is running.

How the size of the redolog files will hurt your database performance ?
Can change the size of the redolog files while the database is running in oracle 9i. ?
What will be its impact on the standby database ?
Thanks in advance.

redo logs that are too small can cause waits on the switches for heavily utilized systems. logs that are too large are a pain the a$$ during recovery. check v$loghist to see how often switches occur - an average of 20 minutes is good; if you have many switches happening back-to-back, that's a bad sign.
you can change the sizes while the db is up. choose a redo group that is INACTIVE, drop it, delete the files, and recreate it with larger files. then force a switch ("alter system switch logfile;"), and do another inactive group. I actually prefer to do as many switches as necessary to make the new group active so I can verify that I didn't screw up before dropping the next group.
not sure of impact on standby database.

Is it possible to increase the size of the police in the finder menu in Lion?

Hezllo,
Is it possible to increase the size of the police in the finder menu in Lion?
Thhanks for your reply.

I see, in Finder you have the ability to see things in multiple views. I would very strongly recommend you use the Find Out How Video tutorials , specifically Finder Basics. You can increase the font size in any view by clicking the View menu - Show View Options where you can increase the font size.

How to reduce the size of a database ?

Hi,
I would like to know what are the possibilities for reducing the size of a database storage.
I have thought about compressing big indexes and tables.
Have you others ideas ?
thx

thxIt depends. Have you evaluated what takes up the space? Do you have data that can be archived? Do you have high water marks that will never be reached? Do you have sparse data that could have free space removed, just leaving expansion space in new or updateable blocks? Do you have unused indices or tables? What type of systems do you have, OLTP, DW, DSS? Is your data normal? Is your app software enterprise? Are your datatypes correct? Is your storage cheap?
So many possibilities!
