Export dmp file size

I want to do a schema export of 2 schemas. How can I estimate the size of the dmp file beforehand ? Can I arrive at an estimate using dba_data_files or something similar ?
Thanks

SELECT SUM(bytes)/1048576 AS mb
FROM dba_extents
WHERE owner = '<schema name>'
AND segment_type <> 'INDEX';
Your dump will be smaller than this.
That is about as good an estimate that you can get -- at least in my experience.

Naming for Export dmp file in Date and Time

Dear All,
Please advise me how to give the file name in date and time stamp for the export dmp file and it's log file.Suggest me in Oracle 9i version.
for example the file name get like this 020420041155.dmp and 020420041155.log where date and time are 02/04/2004 11:55 respectively...
Kindly let me know the syntax of filename to be given along with the EXP command..
Thanking You,
Ragesh

Hello
I don't think you can get the exp command to automatically name an export for you. The only way I think you would be able to do it is through a shell script or something where you format the file name yourself and pass it to exp. If you wanted to you could generate the command line through a SQL statement and then spool it out to a file i.e.
spool runexp.bat
select 'exp user/pwd@tns file='||TO_CHAR(SYSDATE,'DDMMYYYYHH24MI')||'.dmp tables=(table1,table2)' from dual;
spool offThe second option isn't as flexible as the first but if it's just a couple of exports you have to do, it will probably prove to be less work

Generate SQL Insert Statement using EXPORTED dmp file

Dear DBAs,
Kindly inform me that is it possible to generate SQL script file using the exported file dmp,
I am looking for some option in import utility that generates script without import any rows in the database
Secondly is there any other way to check the validity of exported dmp file data validity without importing it back into the database.
Regards,
Asif

Hi Satish,
Yes you are correct the insert into statements won't be avaliable using either the indexfile or the show parameter.I had given these two options as per his 1st post requirement where he had mentioned
>

So, i thought he needed to see whats all objects are in the .dmp
Apologies for my 2nd post.

Create a test DB from the export DMP file

Hi Gurus,
I was able to create the DMP file by export and transfer it to the test machine. It is a Windows OS.
Now in this machine I recently installed Oracle 11g. And I have this export *.DMP file in a dir.
I need to import the DMP file which into this newly created database to give a test database in 11g.
I also created the user for which the export is done.
I need to know how to import the DMP file. I am new to this import-export business.
Thanks

Is it possible to import an Oracle 10 (export .dmp file) into Oracle 9 db ?

hi Oracle Guru's
Is it possible to import a oracle 10 (export .dmp file) into an oracle 9 database ?
I tried & got the following error ...
IMP-00010 not a valid export file, header failed verificationperhaps their is a work-around ?
thanks

Hi
You can take export from a previous version and import to a later version. Having said that, there is still a workaround to do what you want.
On 9i server add a connect string for your 10g instance. Then use 9i export utility to export 10g data. That way your export will be compatible with 9i. You can then import the data in your 9i instance.
To create connect string you can either use Net Configuration Assistant or manually edit TNSNAMES.ORA file in your 9i server.
Hope it helps.

Aperture is exporting large file size e.g. original image is 18.2MB and the exported version (TFF 16 Bit) is 47.9MB, any ideas please

Aperture is exporting large file size e.g. original image is 18.2MB and the exported version (TFF 16 Bit) is 47.9MB, any ideas please

Raws, even if not compressed, Sould be smaller than a 24-bit Tiff, since they have only one bitplane. My T3i shoots 14 bit 18MP raws and has a raw file size of 24.5 MB*. An uncompressed Tiff should have a size of 18 MP x 3 bytes per pixel or 54 MB.
*There must be some lossless compression going on since 18 MP times 1.75 bytes per pixel is 31.5MB for uncompressed raw.

Export dmp file

I have a export dmp file, there is any way i can find it out this dmp file is whole schema, or whole database, or table level backup. what is the scama name or database name or tables name backup.

Hi All
use imp utility connect to user with dba privilege can be system, in addition to verify the variable oracle_sid and to verify that bd is one operative since password and user will read it of this instance.
The mails above is true, import all structure in flat files with no data, this is the only way of see the content.

Export dump file size

i am exporting one schema.The total size of all the objects in that schema is 70GB.When i perform export on that schema the the size of the dmp file will be 70GB or less?Can any there out to help me.
OS:Solaris
DB Version:9.2.0.6
Thank you..

Hi,
When you do an export, you are only exporting the data. Other objects, such as indexes are only exported as a description so take up virtually no space. A general rule of thumb is to work out the actual amount of used data blocks you have, remembering that tables can have allocated space that is empty, and this will give you a size that is probably slightly larger than the export, maybe by about 10%. Also, export files are highly compressible. So if you need to save space, you will usually get about 80 ~ 90% compression ratios.

Exported media file size issues Sometimes one size, Sometimes another without making any changes in FCPX?

Hi there
I'm having some strange issues with files sizes from
Share>Export Media
I'm not changing anything about the video (just moving an audio track forwards and backwards ever so slightly to try and get it to the correct timing), nor am I changing anything about the way I export the video.
I am always using the EXACT same settings
Sometimes finder states my video is 1.15GB, sometimes its states its 3.8GB
But then when I close Finder down and then go back into Finder again to find the file it states its gone from 1.15GB to 3.8GB
I'm not sure if this is a error with my system or Final Cut Pro X?
By the way I'm running 10.0.5
Thanks

Bob,
Well, the issue has gone to press and I have upgraded to Snow Leopard and CS5. Initial tests show that the problem still exists, and that it is related to the XML tags. The problem occurs both with legacy (CS4) documents and documents created from scratch in CS5. As I mentioned before, it only seems to happen when overrides are applied to paragraph styles.
Here is a sidebar as exported from InDesign. Overrides were applied to the two headlines to modify color, point size and baseline shift:
The file with XML tags, packaged and opened in InCopy CS5:
The same file with XML tags removed, packaged and opened in InCopy:
OK. Now is when things start to get really interesting.
I thought perhaps that exporting the InDesign file as an IDML document, then reopening it, might perhaps fix the problem. But, no. In fact, when I reopened the IDML file in InDesign, the font styles were broken in _exactly_ the same places as they were in InCopy. Apparently, whatever problem InCopy is having with the XML tags is being duplicated by the IDML export. (Do these processes share the same file format?)
For example, here is a title page from the magazine as a screen grab in InDesign. Overrides were applied to the top headline on a line-by-line basis:
The same file, exported as an IDML file and reopened in InDesign:
As with InCopy, when the XML tags are removed, the IDML file reopens in InDesign just fine. Unfortunately, removing the XML tags is not a option. We need them to repurpose the content after it goes to press.
This is a real bug, and for us it's a serious one. I'm surprised it hasn't come up before. Is there any way to draw this to Adobe's attention? I'd be more than happy to share any of these files if that would help.

Exported mp3 file size is huge!

Does anyone know how to control the size of an exported song? For a 5 minute track I'm getting a 60Mb MP3!! I'm guessing this is done by setting the a different bit rate for the exported song but can't find any options in Garageband to do this.
With such huge file sizes it makes it difficult to share the song through my website.

No, you're not getting a 60 MB MP3, but a 60 MB AIFF file, and that's the regular size for uncompressed audio files. The bitrate in GB is fixed, and you wouldn't want to change it. Instead, convert the file into an MP3 or AAC in iTunes.
(Come back if you need help with doing that.)

InDesign - Export PDF file size

Hey everyone. I use InDesign to create my resume for job apps and whatnot. I've found that many corporate sites only accept file sizes under a certain limit (usually 500kb or smaller). My resume is usually around 590-610kb. Is there any way that I can reduce the file size without losing significant quality, or even any?
Cheers.

So I need to d/l adobe acrobat?
OK, so this sounds like you don't have a Creative Suite package, or perhaps you are using Creative Cloud and didn't install Acrobat Pro.
The free Adobe Reader will not help you to optimize a PDF, you need the full, paid, Acrobat application. Uwe's suggestion to distill might get you a smaller PDF, but again, without Acrobat you won't have Distiller. There are a few freeware Distiller clones that would probably work for plain text, but I doubt there's much that can be done to bring the size down on a file that has nothing but text in it without removing the non-graphic disposables like metadata, and the embedded page thumbnails, which requires the optimizer.
It occurs to me that one reason your exported PDF might be large is that ID always embeds fonts unless they are restricted. If you are using common system fonts that you know your viewer will have, you can distill PDF without embedding fonts and save a couple of bytes. I just pulled up a random page from a student paper, which has about seven fonts in use. The usage audit says they total a bit over 2mb.

Exporting .dmp file from 9.1.2 to 9.0.1.1

Is it possiable from me to export a .dmp file generated from 9.1.2 to oracle 9.0.1.1

Dear Carlo & Chris, May I ask you to clarify on below comment which is mentioned in Release note of CUCM 10.5
I don't understand why Cisco has mentioned this, if its not required ? I would appreciate your any inputs.
Preupgrade COP File
If you are upgrading to Cisco Unified Communications Manager Release 10.5(1), or later, from a release earlier than Cisco Unified Communications Manager Release 10.0(1), you must download and install ciscocm.version3-keys.cop.sgn on every node in the cluster. This Cisco Options Package (COP) file has the RSA keys that are required to validate the upgrade. Missing RSA-3 keys will result in status errors in the Software Installation/Upgrade window of the Cisco Unified Operating System Administration interface.

Why Is "Export Small File Size" Large?

Hi, I work in CS3. Out of 100 brochures, I have two brochures that will not export to a small file size PDF. The settings for export are all the same. What else should I be looking for? The sizes are usually 1 MG. These particular 2 brochures are 5 - 6 MG. What can I look for to correct this?
Thanks

Small size is very dependent on the contents being exported to PDF. Images are readily compressed. Text and vector data isn't. Thus, if your content is primarily text and vector, it is very unlikely that the content can be compressed signficantly more via change of settings.
Another factor that can relate to image compression is use of any duotones that use spot colors. Such images cannot be JPEG-compressed, only ZIP-compressed.

Lightroom 5 exporting wrong file sizes?

I am having trouble with Lightroom 5 exporting images at incorrect file sizes. For example, if I use my export preset for images with long edge 2500 pixels and maximum size 1000k it is exporting images at 1500-2500k.
Is anyone else experiencing this? I am wondering if it is a bug.
Thanks

I never had a problem with it in LR4. The example I gave was one of many options I tried. At the other end I asked it to produce smaller files (eg 1500pixels long edge) with a 1000k maximum and I could only get them to output at around 160k.
I have since realised that I neglected to mention that I was using LR/Mogrify2 plug in to add a text graphic to the images. I experimented with turning that option off and I was able to produce a 2500px long edge file at 996k. As soon as I turn that option on again the file ouptuts at 1600k (where I have specified at 1000k limit).
This was never a problem with LR4 so there is a conflict or a bug somewhere.
Is anyone else using a LR / Mogrify 2 plug in and experiencing unpredictable results? I have the option to use LR / Mogrify 2's version of ImageMagick checked.
Message was edited by: Shipp
So I just did further testing. It seems that LR5 cannot control the maximum file size when working with Lr / Mogrify 2. If I ask the plug in to resize the image and control the maximum file size I can produce a file with long edge 2500pix, 1000k maximum size and the text graphic with no problem at all, as I used to be able to do with LR4. I will contact the plug in developer and see if they are aware of this.
