Approximate physical size of database

Hi Experts,
I wanted to know my physical size of database like datafiles, tempfile occupied currently and free space can any one let me know do we have any query to get the information.
Thanks,
S@ntosh.

If the total is for example 6123MB, what does this tell you? How does this enable you to manage the database better? Or understand database performance, or database growth? That number alone is a pretty meaningless number.
Also, what about database's footprint ito control files, archive logs, rman backups, bdump, udump, cdump and other directories? What about database tables that use BFILE datatype referencing external files and using that as part of the database's data? Etc.
Database size of x amont of MB/GB/TB is IMO a number that says nothing about the database - and is pretty much useless. Database space is not just a single number. It is much more complex than that. The important thing is to understand what space is needed, for what purpose, and how Oracle uses it.

"The ACS Database needs to be compressed as a part of maintenance operation. You can run the acsview-db-compress command from acs-config mode to reduce the physical size of the view database when there is a difference between the physical size and actual size of the view database. ACS 5.5 stops only the log collector services during compress operation and will be up and running after the compress operation is completed. You need to enable the log recovery feature to recover the log messages that are received during the database compress operation.
In ACS 5.5, database compress operation is automated. You can check the Enable ACS View Database Compress check box to compress the ACS View database automatically every day at 5 A.M. The database compress operation is run everyday automatically at 5 A.M whenever there is a need."
I already tried to manually compress the DB via "acsview-db-compress" without any effect.

Hello,
You're running into bug CSCum51180. The alarm should be a warning, not critical, and should be raised only when the physical size exceeds the actual size by more than a gigabyte (in your case, the difference is very small, 1.5 vs. 1.48).
The fix should be present on a future patch.

Size of Database

Experts,
We are in ahead of Archiving project in SAP.
I want to know, how I could find size of Database tables under Objects.
For eg . Object MM_EKKO under that there many database table (A068,A081 etc)
I want to know size of that database table.
I know function DB05 and DB02 but it is very time consuming to run one record.
Is there any other table name or any other option to find?
Thanks

Hi,
DB05 calculates "Total number of rows * Requested bytes per row" which is not a physical requirement over the tablespace. This is a simple approach and can be used buffer requirements of the table, for example.
DB02 shows space allocation of the table, over the tablespace. The data is not store raw format when the database write the data to the datafile. It performs some algorithms to save space then writes to the datafile.
Because of this reason the calculations are different between DB02 and DB05.
Best regards,
Orkn Gedik

How to view the physical size of objects

Hi
Please advise how to view the physical size of objects like tables, indexes, materialize views etc.
Wishes
Jawad

To see the physical size of objects like tables, indexes, use
USER_SEGMENTS where SEGMENT_TYPE=table/index/partition etc.
But for views/packages/java/trigger, you can only see rough estimate in USER_OBJECT_SIZE

How to make AI document display same physical size as mobile screen?

I know this seems like a bush-league sort of question, but I can't find the answer.
I'm designing some screens for an retina display iPad and I just want the illustrator document on my 27" thunderbold monitor (at 109 ppi) to have the same physical dimensions as the physical iPad screen (7.75" x 5.81"). Maybe its so obvious that no one talks about how to do it. I do feel a little embarassed that I haven't figured this out.
Regardless of whenther I enter the doucment dimensions in inches or in pixels the resulting document is never the same pysicial size as the iPad's screen. And since Illustrator deals in vectors it doesn't have any notion of PPI that I can use to bring inches and pixels into alignement so that what I see on my monitor is the same physical size as what's in the iPad.
All i want is the AI document displayed on my monitor to be the exact same size as my iPad's screen. Can anyone help?

Photoshop has a "Screen Resolution" feature in its Settings which allows you to enter your screen resolution of 109 and this will display the physical size of images when you choose Print Size from the View menu. It simply will display the image at the appropriate zoom level for you. Unfortunately Illustrator doesn't have this, it always assumes that your monitor is 72ppi resolution. The problem with implementing custom monitor resolution in Illustrator is that it is a vector program and unlike Photoshop it doesn't have a ppi settings for its vector objects which are resolution independent. For the use of its rulers and numerical dimensions input when set to pixels, it has to assume an eventual ppi rasterization of the vector objects. If Illustrator uses the same feature like Photoshop then the same Illustrator file will show different pixel dimensions depending on which monitor it is displayed which may cause a much greater confusion than the problem you have now.
To find the physical size in Illustrator, right click on its ruler and set it to units that you have on a real life ruler. Then put the real life ruler on your screen and change the zoom level until the rulers in Illustrator are the same size as the real life ruler. Then write down the zoom level and use it again when you want to check the physical size of your work.
I think with your 109 ppi monitor, the zoom level should be about 152%

Is it possible? for checking dataguard database application as well.

but i just want to know that can i start EBS application services and nagivate the application.Without distrubing my primary database and application.You should not do as the moment you open the standby database it becomes invalid.

Adding Temp tablespace to physical stand by database?

I am getting the below error when i try to load data using SQL loader from physical stand by database to another database after making the physical stand by database in read only mode.
ORA-25153: Temporary Tablespace is Empty.
On primary database when i query
SQL>select ts#,name from v$tablespace;
TS# NAME
2 TEMP
On physical stand by when i query
SQL>select ts#,name from v$tablespace;
TS# NAME
2 TEMP
On primary DB when i query
select name from v$tempfile where ts#=2;
NAME
/dev/vx/rdsk/oradata/tempfile0101
On standby when i query
SQL>select name from v$tempfile where ts#=2;
no rows selected
At this point do i need to add datafile to the TEMP tablespace of stand by database or just need to add TEMP tablespace to stand by database.?
DB version:9.2.0.6
Thank You all...

Can you make sure that /dev/vx/rdsk/oradata/tempfile0101 is copied to standby site during the standby creation. Often it happens that the hot backups are copied to standby ste and generally they dont contain temp files. If the files is present , then i'll suggest you to do a quick bounce of standby instance to make sure that controlfile attempted to access it. You can also try recreating the standby control file on promary and copy it to standby site along with the tempfile and start the instance with new control file.
If you want to add temp files to the standby instance, the only option you have is to add them on primary site. If you have standby_file_management as auto they will get copied over. If not you can copy the files to standby instance and restart the recovery.
Please let us know if any of the hints are applicable to your case.

Physical size of dimensions and composites (Express and Oracle OLAP)

Hi, have a rather odd question re: the physical size (in bytes) of composites...are they affected by the dimension sizes?
I.e. if I define a dimension "Org" as:
define org dimension text width 10
will that result in smaller composites than if I define it as
define org dimension text width 30
? i.e. given that everything else if equal (same number of values, same # of tuples, etc.) does the physical definition of how wide a dimension is affect the size of the composites that use that dimension?
p.s. need to know this for Express, but if Oracle OLAP doesn't behave the same I'd like to know that also.
Thanks!
Scott

A 5 dimensional composite has keys built of 5 4-byte dimension positions. There is a copy of the 20 byte value stored indexed by physical position that we use internally to determine the value of the base dimensions. Also there is a copy stored in a hash table used to take the base dimension values and convert those back to a physical position (that's 20 bytes for the key and 4 bytes for the physical position).
Finally, we have internal structures ("inversions") that we use to essentially do "limit composite to base dimensions" for looping (for each base dimension value, a list of physical positions that have that base value in it), at 4 bytes per dimension or another 20 bytes.
That's 64 bytes. Yeah, it's not cheap, but compared to a dense variable, you save a ton of space. I seem to remember a calculation someone did a long time ago that said that composites were net smaller for anything less than 20% dense.
I'm not surprised that under certain conditions you can find a better data layout. Certainly the overhead of storing dense data is tiny compared to a composite. If you are clever (or lucky) in your segmenting, you can take advantage of the "holes" in the data to improve the storage. The "holes" (large groups of NA values) can go for many pages, if the faster varying dimension size is large, and won't be stored.
Oracle OLAP contains various improvements over the Express code. I believe we now use compressed bitmaps to store the inversions, rather than lists of values, for a substantial savings. There may be other changes as well (I'm not current on the details of the dimension storage).
Hope this helps.

Could you please tell me is there any way to reset the HWM at Datafile level and how we reset the HWM of those tables having Materlized view?

Hello,
I'm not really sure what is the problem here? Everything seems to be OK. From what I have seen ,your database can stand to be resized down quite a bit.
The actual amount it can be resized down depends on the highet HWM for the segments in the datafile, as in:
set line 200col file_name format a90
select file_name,
ceil( (nvl(hwm,1)*&&blksize)/1024/1024 ) USED_SPACE,
ceil( blocks*&&blksize/1024/1024) SIZE,
ceil( blocks*&&blksize/1024/1024) -
ceil( (nvl(hwm,1)*&&blksize)/1024/1024 ) ECONOMY --how much of the space can be reclaimed
from dba_data_files a,
( select file_id, max(block_id+blocks-1) hwm -- here we get the max hwm for the datafile from the extents residing within it
from dba_extents
group by file_id ) b
where a.file_id = b.file_id(+)
and ceil( blocks*&&blksize/1024/1024) -
ceil( (nvl(hwm,1)*&&blksize)/1024/1024 ) > 2000
>
You can also do a reorganization of the segment you suspect has a high degree of reclaimable space within its extents (high HWM and low actual space used). You can run segment advisor to help with that.
Hope it helps,

Restricting the physical size of wifi network

Hi,
I'm planning to cover the 80x80m building by the amount of 1131AG APs and WLC4402 controller. But the strong client's demand is to physically restrict any posibilities of wifi connections from the long distances (100m and more from building).
Is there a feature in Cisco wifi to drop any incoming connections in case if client is 100+m from AP? (I mean that client's power is high enough for this)
What are the regular methods of resricting the physical size of wifi networks?
Thanks.

This is exactly the case for knowing and understanding antenna types and patterns (i.e., what those goofy circle charts mean).
By using an antenna's pattern, coupled with power management, you can easily limit the radiation and external exposure of the signal.
You don't have to know every single antenna, but just be familiar with the general types, and how to interpret the charts.
Here's a pretty decent explanation on Cisco's main site:

How to calculate the size of database (a different one)

Hello Friends,
I am told to move the data from server to another machine (cloning is one very good option, I agree. But I expect a different answer regarding exports and imports). so How should I go about the task. The destination machine has got unlimited space. So thats not a problem. My questions are :
1) How should I start the task ( I generally go for studying the structures and their sizes. Is it ok ?)
2) If I am using Unix machine and there is a limitation that my server will not support file sizes of more than 2 GB, What should I do ?
3) Shall I have to go for a full database backup or fragment the task ? If I do that , there are many schemas, so it will become tedious. But full backup will exceed OS size limitation. What should be done ?
4) Is there anyway, I can go through a dump file, to find out, the database objects present inside that and note the related dependencies.
Please respond.
Regards,
Ravi Duvvuri

1) They are Unix machines. So will the size problem occur(if there is a limitation). How to overcome that?
If the OS are of the same version you will have any problem. Regarding the storage only you have to have space in disk to store the datafiles, redo logs and controlfiles and nothing else.
2) I am trying Export/import measure. Though there are other good methods, I just want to explore the full capabilities of Exp/Imp
r.- Recreate the controlfiles is more effective and fast if the OS are of the same version.
3) And the oracle version is 9i 2. (If I have to perform this on 8i (both source and destination, will the methods are going to differ ?)).
R.- The method is the same for 8i/9i/10g.
How should I go about doing this export/import ?
r.- To use this method you have to have the original database started.
To recreate the controlfile without having the datafile that you mentioned you have to get out it from the CREATE CONTROLFILE sentence and that's it.
For Example: I mean, if your database has 8 datafiles and you have only 7, you have to include only 7 in the CREATE CONTROLFILE sentence.
