What is impact to MDF file size if change database to simple recovery mode

Hi,
Currently I have a Database with 27GB MDF and 80GB LDF.
If I change from Full recovery to Simple recovery mode, would LDF information be transfered to MDF file and make
MDF file size exceed 100GB?

Hi
May I know how to perform point in time recovery? Currently the only backup we perform every 4 hours is the server OS snapshot.
Example :
1. Now is 6pm and some error transaction occurred.
2. We can perform 3pm server OS snapshot recovery on the mdf file. ( We would lost 3 hours data in this case )
3. Could we apply the ldf transaction log after OS snapshot recovery and roll it forward till 5:50pm?
You would be able to perform point in time recovery if you have
1. Database configured in full recovery mode
2. You were taking transaction log backups.(of course with full backup or may be differential)
In your scenario applying snapshot wont help you.What you have to do it you should have full backup in place .If you had full backup ,like full backup at 3 PM then you would have restored it with no recovery.After that suppose you took tansaction log backups
every on hour then restore 1 PM ,2 PM and 3 PM log backup all in nore covery.
Now i should have mentioned first but before restoring full backup you can also take tail log backup read this article
http://technet.microsoft.com/en-us/library/ms179314.aspx
So now after full and all log backups are applied with no recobery apply tail log backup with recovery and its quite possible that you might not have a data loss or in some scenario very small data loss( not 3 hrs as you would have with snapshot)
hope this helps

Existing Replica MDF file size is increased in size than the New replica install

Please I need help here.I really really appreciate your help.
Here are my scenarios:
We have an application with replicated environment setup on sql server 2012 . Users will have a replica on their machines and they will replicate to the master database. It has 3 subscriptions subscribed to
the publications on the master db.
1) We set up a replica(which uses sql server 2012) on a machine with no sql server on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 33gigs and ldf has grown to 41 gigs.
I went to sql server management studion . Right click and checked the properties of the local database. over all size is around 84 gb with little empty free space available.
2) We set up a replica(which uses sql server 2012) on a machine with sql server 2008 on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 49 gigs and ldf has grown to 41 gigs.
I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
3) We set up a replica(which uses sql server 2012) on a machine with sql server 2012 on it. We have dropped the local database and recreated the local db and did the initial synchronization using replmerge tool.
The mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
Why it is allocating the space differently? This is effecting our initiall replica set up times. Any input will be greatly appreciated.
Thanks,
Asha.

What is the max mp4 file size?

Does anyone know what the max mp4 file size that can be imported into iTunes for sync with ATV is?

I got HandBrake to work. What settings do you recomment for ATV? When I used the Apple Tv setting it worked pretty quick and I could view the file in iTunes, but it would not import into ATV. I got a message saying it was not playable on ATV. The "Normal" setting (h.264) seems to work good. I did a few minutes of a movie and it looks good and works with ATV, but it seems to take a lot longer (hours).
With Handbrake 0.9.1, always select "Apple TV" under the "Presents" column on the right side of the window. When you say it is "not playable on ATV" do you mean by streaming or syncing or both?

SQL mdf file size vs ndf

Hi,
If multiple database files are created does the mdf file hold any of the row data or does is it exclusively hold the table definitions?
If the mdf file is exclusively used to hold table definitions i'm assuming I can size it quite small?
Thanks
Mr Shaw

As Olaf said, it completely depends on how and where you create the ndf file.
If you create additional ndf files in the primary file group itself, then it utilizes both the mdf and ndf file in a round robin fashion and both grow at the same pace.
If you want you can segregate mdf and ldf by different methods.
One option is to keep the mdf file only for system objects and all user objects in ndf files . Check the "Filegroup" section in this article -
http://www.codeproject.com/Articles/43629/Top-steps-to-optimize-data-access-in-SQL-Serv
Another option is to move just indexes or just few objects .Check this article for moving data from mdf to ndf -

Impact of data file size on DB performance

Hi,
I have a general query regarding size of data files.
Considering DB performance, which of the below 2 options are better?
1. Bigger data file size but less number of files (ex. 2 files with size 8G each)
2. Smaller data file size but more number of files (ex. 8 files with size 2G each)
I am working on a DB where I have noticed where very high I/O.
I understand there might be many reasons for this.
However, I am checking for possibility to improve DB performance though optimizing data file sizes. (Including TEMP/UNDO table spaces)
Kindly share your experiences with determining optimal file size.
Please let me know in case you need any DB statistics.
Few details are as follows:
OS: Solaris 10
Oracle: 10gR2
DB Size: 80G (Approx)
Data Files: UserData - 6 (15G each), UNDO - 2 (8G each), TEMP - 2 (4G each)
Thanks,
Ullhas

(Including TEMP/UNDO table spaces)Remember this when tuning I/O: The fastest I/O is the one that never takes place! High I/O may very well be a symptom of unnecessary FTS or poor execution plans. Validate this first before tuning I/O and you will be much better off.

What is the maximum excel file size that can be converted to pdf?

Currently I am trying to convert a excel file of 37 mb by using pdf generator. And it fails with the exception as java.lang.OutOfMemoryError: Java heap space; nested exception is: java.lang.OutOfMemoryError: Java heap space.
Waiting someone help! T_T

Open in PS and print to the Adobe PDF printer. However, a 448MB TIFF seems huge. At 200 dpi and 24 bit color (millions of colors) that leaves you with a 61inX61in graphic. Even at 600dpi, that is 20X20.
For us to help you, please indicate exactly how you are trying to convert from PhotoShop. For Acrobat, are you trying to open the TIFF in Acrobat directly? Is the TIFF a single sheet, or multiple sheet? There are a lot of unanswered questions for us.
One of the limitations on file size is the size of the temporary PS file that is created in the PDF creation process. This PS file is created in the TEMP folder that is limited by MS. So you might try emptying the TEMP folder.

What can I do for "File size too large"?

Spent 9 hrs creating a slideshow that I saved. Closed PSE 11 and reopened and can no longer find the slideshow. When I select Find, Media type, Project, nothing appears, but there is a gray box in my grid that says "File size too large". Is this my slideshow and if so how can I recover it? I am sick as this was a large time investment for my daughter's wedding which is very soon! Please help if you can.

I don't know anything about slide shows but if a picture is too large this is just a warning message, if I click a pic with this message it does show up. Have you tried clicking the thumbnail?

Why does text in Smallest File Size PDF change point size and vertical scaling?

If you have a document with 6 pt. type (no scaling) and Save As a Screen-Quality PDF, when you open that resulting PDF in Illustrator, the 6 pt. type has become 5.1 pt. type with vertical scaling of 117.65%! Normally, I would have no reason to open the PDF in Illustrator, but our clients are doing it. They want the smallest possible PDFs but still want to be able to check the point sizes for legal reasons. If you Save As a High Quality Print PDF, the type is fine, but that won't always work if there are alot of images and the file size needs to be kept as small as possible.

sorry for 2 posts, technical problem with forums and images.
Leading changed to 7.2, but as you know when going to pdf paragraphs are broken up into seperate lines.

Spooling of a query generates different file sizes for different databases

Please help me regarding a problem with spooling. I spooled a query output to a file from two different database. In both the databases the table structure is the same and the output produced only one row. But the file size is different for the databases. How can this problem occur? Is there any database parameter need to be checked? Both the databases are in same version 10.2.0.1.0.
before running the spool i did a
sql> set head off feedback off echo off verify off linesize 10000 pages 0 trims on colsep ' '
on both the sessions.
In one database the filesize is *1463 bytes* and on the other the filesize is *4205 bytes*.
Please help me to find out these discrepancies.

hi Mario,
I think you are not getting my point. Both the files contain the same output but their sizes are different. This is due to the no of blank spaces between columns. I wanted to clarify why there is a difference between two filesize when the query output is the same.

Reducing file size by changing the photo size?

I inherited a bloated pages file with some photos over sampled at 14Mb+ Probably should be about 500k.
I want to open the file's package contents and edit the images using graphic converter. So far my attempts have resulted in the physical size reducing on the page. Anyone with a tip to reduce the resolution of the photo with out the result shrinking on my layout?
thanks

Well to answer my own question
1) for PDF files–open in preview>>save as>>select quartz filter- reduce file size.
2) for tiff/jpg open in image editor and change the resolution. Save as to NEW location.
in pages select the image and under format>>advanced menu "set as media placeholder" drag new image to this place to replace. TIP drag the icon in the title strip at the top of the saved file instead of locating in finder.
NOTE: for 2 if the image has been masked the pages image will need to be resized.
Of course this only works if the placed images have high resolution to start with or have been shrunk in the pages layout.
I had a 120Mb 5 page file that is now under 10Mb

What is the appropriate .tif file size for 1080p Movies in Final Cut Pro?

Doing pans and moves on stills for projected show 1080. What size should I order my final still images? and is it also 72dpi? thanks

FCP can handle images up to 4000x4000 pixels.
Still, it's best to keep the images as close to the video resolution as possible as this reduces the overhead of the program used to dynamically resize. In addition, FCP is not the most sophisticated app for resizing images - Photoshop will do a better job.
Good luck,

What is the Max import file size for Aperture

I'll some times shoot film and get very large scans done as Tiffs or Jpegs. 500MB+ What is the Max that Aperture can manage, or is it only determined by the Mac configuration?

I'm curious to know this as well before upgrading. Hopefully it has been improved in Aperture 3. I know Aperture 2 only supported up to 250MB which was near useless if you'd ever made any significant adjustments and edits in Ps and saved it as a .psd.
All my medium format (digital and film scans) and large format scans give me the maroon "Unsupported Image Format" error while trying to view in Aperture 2.

What is the iBook maximum file size?

I have mapped out my 'textbook' with 30 chapters, some text in Chapters, hundreds of photos and only one short video at the moment. It is almost 1GB now!
I am worried that when I do put more video in, the remaining 1Gb will be quickly used up. I will have to prioritise text and photos to produce a good textbook.
Is 2Gb going to be the absolute maximum?
The 'Life on Earth' demonstration was almost 1GB with only 51 pages (probably because it had lots of short video clips?).
If the size of the textbook reaches 2Gb will it still be viable on entry IPad 1, which most schools will be using?

Lots of people had trouble with 'Life on Earth' at 1Gb - see customer reviews on the download page.
I did too and I kept having to delete the app and start again.(iPad2)
Is this a download problem?
Will it work in schools at twice the size?
