ITunes Space Consumption

I have about 3,700 songs on ITunes:
Does it make sense that it would consume close to 16GB's?
If I have downloaded albu, graphics (which I assume also consumes space), how can I turn off and delete existing to free up space?

"Does it make sense that it would consume close to 16GB's?"
Yes. It makes perfect sense. That would mean an average of 4.25 or so MB per song. At highest quality they would take up more space than that.
"If I have downloaded albu, graphics (which I assume also consumes space), how can I turn off and delete existing to free up space?"
Doubtful that takes up much space at all.

Space Consumption by Schemas

Hi All,
How do I determine space consumption of each schema present in my DB's ? Is there any tool or any Query that can perform this task ?
Thanks

Disk Space Consumption - iTunes TV Videos

I am in the process of buying a 60G V ipod. I am curious how much disk storage is consumed by say a 42 minute "Desperate Housewives" TV file. Also when you purchase the video clip on iTunes, do you have the option to set the bit rate to modulate the quality vs size tradeoff like you do on music files? Thanks in advance for the responses.

It will all depend on he data rate at which your movies (or purchases) are encoded. A 25 minute episode of Doctor Who targeted as a 100MB file has a typical rate of 540-560 kbits/sec. Using a 2-pass encode, the rendering on the iPod remains very sharp and crisp -- quite viewable on an SD TV, Thus, you should expect to put about 5 such shows on your iPod per 1G of space used. You can, of course double or triple this rate, but the increase in quality will be minimal as far as the iPod screen is concerned. Hope this is of some help.

Fix for iTunes Space Calculation Issue in Windows 7?

I moved my iTunes library from a Windows XP, to Windows 7 PC. It is a little smaller in the Windows 7 environment because I deleted all of my Podcasts, some Video, and Picture files. Even with the deletions the space calcuation in Windows 7 is incorrect, and my iPhone4 fails to sync. I can move back to the XP environment and sync without any issues.
When is this issue getting fixed?

Well *** Apple. Still no fix in iTunes 10.6.1.7. UNACCEPTABLE.
You know there is an issue but sit and ignore it.
Great customer service and support.

ARCHIVELOG space consumption

Hi!
I am new to DBA world and would like to ask how much space is consumed when ORA XE database is in archivelog mode. That is if XE is limited to 5 GB of data how much of that space is ment to be for archivelog segment. Furthermore what exactly(besides DATA) is consuming those 5 GB of available space(db objects, data, ???)?
Thank you in advance,
Marinero

Thank you C.
I wasn't sure weather files for archivelog were part of those 5 GB DATA space. I was thinking that if you have lets say 2 of 5 GB of space consumed and last backup was made when there was only 1 GB of data in DB that actual consumption is 3 GB(2GB for data and 1 GB for archive log). Thank you once again for clarification.
Regards,
Marinero

Unecessary Space Consumption

ok sooo when you plug in your ipod and it comes up under devices and you click on it to view it. The bar that shows you how much you ipod holds and what catagories are taking up what about of space, is showing that i have 10 gigs being taking up under the catagory of OTHER. and i have no idea what this other is. Ive checked contacts, tv shoes, podcasts, anything and everythign that isnt Music videos and Photos. and i cant find anything on the ipod either. Does anyone know whats taking up this space

i figured it out guys

ITunes Ram Consumption

Hi there,
I'm using Windows Vista. Even the 64bit version. I know, I know, it's not officially supported by Apple (which is a first evidence how ridiculously bad iTunes is coded), but I'm using it anyway - I have to, since there's hardly other software to use with an iPod.
Besides the fact that iTunes was actually able to ruin the S.M.A.R.T.-Tags of my Raid-Harddiscs while trying to import corrupt video files, I just discovered a other nice ... let's call it "feature". Or "5 years ahead of other ..." Oh sorry, that was a different product.
My music collection has about 200 albums, of which i guess 170 have an artwork. An artwork picture's size is about 400kb. Since the "Cover Flow"-view is extremely slow the first time you use it, iTunes loads all the artworks into RAM, which is nice. You might expect it to use about 170 times 400kb of RAM, which would be 68 MBs. Let's give it some additional information and so we estimate it to use 100 MBs... Right ?
Well, the truth is, iTunes consumes the incredible amount of 612MB of RAM. Let's remember, it's basically a FREAKING MUSIC PLAYER. Music players usually play music. Playing music is a background task. Background tasks are not supposed to use over half of your computer’s memory (in my case a quarter, still way too much).
Okay, you might think that iTunes reduces its memory usage once it's back in background and the user finished scrolling through his album artworks, changed the view to "list view" or minimize the window. Well, it doesn't. You have to close it to get it out of your memory.
Ok, so let's see what kind of feedback I get ...

Sql server log shipping space consumption

I have implemented sql server logs shipping from hq to dr server
The secondary databases are in standby mode .
The issue is that after configuring it , my dr server is running out of space very rapidly
I have checked the log shipping folders where the trn files resides and they are of very decent size , and the retention is configured for twenty four hours
I checked the secondary databases and their size is exactly same as that of the corresponding primary databases
Could you guys please help me out in identifying the reason behind this odd space increase
I would be grateful if you could point me to some online resources that explains this matter with depth

The retention is happening . I have checked the folders they do not have records older then 24 hours .
I dont know may be its because in the secondary server (Dr) there is no full backup job working , is it because of this the ldf file is getting bigger and bigger but again I far as my understanding goes we cannot take a database full backup in the stand
by mode .
The TLog files of log shipped DBs on the secondary will be same size as that of primary. The only way to shrink the TLog files on secondary (I am not advising you to do this) is to shrink them on the primary, force-start the TLog backup job, then the copy
job, then the restore job on the secondary, which will sync the size of the TLog file on the secondary.
If you have allocated the same sized disk on both primary and secondary for TLog files, then check if the Volume Shadow Copy is consuming the space on the secondary

Cluster and space consumption

I'm confused about some thing in regards to clusters. I have about 1GB wort of data when it is not in a cluster, just in a normal table. If I create a cluster and insert the data in to this cluster it consumes more space, and that was fully expected. When I tried the first few times it took 13GB of space. The table space was 30GB large and contained a few other tables. Then I cleaned out the table space so only 2% of the space was used and added another 30GB to the table space and ran the test once more. Now it is consuming more than 40GB and is still not completed. So my question is does the size the cluster consume depend on the size and available space of the tablespace it is in? Is there a way to limit the size it is allowed to use other than to put it in a separate tablespace?

Hi Marius,
First, by "cluster" you mean sorted cluster tables, right?
http://www.dba-oracle.com/t_sorted_hash_clusters.htm
So my question is does the size the cluster consume depend on the size and available space of the tablespace it is in?These are "hash" clusters, and you govern the range of hash cluster keys, and hence, the range where Oracle will store the rows.
http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10739/hash.htm
Oracle Database uses a hash function to generate a distribution of numeric values, called hash values, that are based on specific cluster key values. The key of a hash cluster, like the key of an index cluster, can be a single column or composite key (multiple column key). To find or store a row in a hash cluster, the database applies the hash function to the cluster key value of the row. The resulting hash value corresponds to a data block in the cluster, which the database then reads or writes on behalf of the issued statement.

Log file disk space consumption

Do I need to care to any log files (excluding website access logs), like mail logs or anything else that could grow indefinitely and consuming much disk space ?
How about the bayesian filter of SpamAssassin - does it have a maximum size limit or grows it forever ?
Any other logs or files or whatever to keep an eye upon ?
Currently I have made these settings on SA:
FTP: Log anything (all checkboxes marked)
Mail: Log anything at level "Information"; archive every one day
Firewall: Log max. of 1000 packets
DNS: Log enabled, level "Information"

I looked into /ezc/weekly and it seems that this does already what I want, doesn't ? It seems that there log files are cleaned up so I feel that anything is okay as it is currently...
Especially since I don't have an real idea which log files are missing there (and finding out their path, which is the hardest task
I just want to prevent that such undeleted logs are eating my diskspace slowly but steadily.

ASM space consumption

Hi,
We have 2 node RAC (10.2.0.3 db) hosted in ASM in AIX 5.3. Our db size is currently 1.8TB. We have purging policy to hold only 3 months data + current month data. Some tables use XML Blobs which take most of the spaces. We do purge from this table as well.
What i believe is, after this purging is complete, a rebuild of the indexes involved in the tables purged will reclaim the space (extents for that matter) used and be used by incoming data thereby the size of the table will not grow more. This has been the case with the application's old version (which was 9.2.0.6 HACMP clustered). But now in this 10.2.0.3 ASM database this is not happening. The purged space is not being reclaimed and only new space from ASM is utilized increasing the ASM space.
Is this how ASM is supposed to behave or any way to make Oracle use the purged space back. Comments are welcome.
Thanks

v$asm_disk will show the free space in whole disk which has not been allocated by any segment. Since deleting some LOB data doesn't release the space from segment, you wont be able to see that free up space in v$asm_disk view. You need to check the free space in tablespace using DBA_FREE_SPACE and also importantly, check the free space in segment itself using DBMS_SPACE package. After purge, once you shrink the lob segment then only that free space will be released by that segment to the tablespace and you should be able to that space in DBA_FREE_SPACE, again not in V$ASM_DISK because the free space is part of tablespace or datafiles and since we never shrink data files, that free space will not be visible in v$asm_disk. But before shrinking LOB, read metalink doc: 386341.1, that will be real helpful.
Truncate should have deallocated all the space by default, so check DBA_FREE_SPACE to find out total free space you have.
Thanks

Request Space consumption

Dear All,
I am pulling data in cube from ODS through infosource. The requests for data in this case always begins with "ODSR". What I want to know is that do these requests take hard disk space? I do know that ODS requests that involve pulling of data from source system does consume space but what about pulling requests in cube from an ODS?
Yours truly,
Abhijit

Hi,
Even if the req ID consumes space, it would be very much small. I think to create some space in your BW system, try to delete the old PSA data. Also make sure that you delete PSA data for Master data attributes that are loaded on daily basis.

ITunes nearing 1GB of RAM consumption! Any ideas to lessen the load?

Hello -
My name is Erick and I'm an ACMT/Network Engineer. Apple-certified, but not Apple-employed.
I have encountered an issue in iTunes which was not resolved with the latest 10.6.3 update and was hoping for any community suggestions or advice.
First, context may be important: I use iTunes primarily as a Home Sharing home-base to stream my TV Shows and Movies to Apple TVs in my home. As a result, it (as well as the iMac) are on 24/7 with the exception of a daily scheduled task which quits and reopens iTunes to sync unwatched media to my iOS devices at 4:30AM.
I have noticed several things with iTunes 10.6 which I have documented in other questions here on the forums (long periods of unresponsiveness, the inability to scrub videos), but this issue may be just as significant and could be a root cause in my other problems. This particular question deals with RAM consumption. I have noticed for years that iTunes is a memory hog, so you won't find me shocked there, but what has shocked me is how the amount of RAM iTunes consumes has risen with the amount of RAM I've installed. I currently use an iMac (mid-2010) with a quad i7 and 16GB of RAM.
I have noticed lately that upon opening iTunes 10.6.1 (and 10.6 before it) that iTunes immediately captures about 250MB of RAM. While I have plenty to spare in comparison, I've noticed that the amount of RAM it consumes swells considerably throughout the day. For example, my iTunes is completely idle right now - no devices are connected, no media is streaming or caching, no store purchases are downloading, and iTunes Match/Genius is not actively scanning anything - but my iTunes shows 605MB of RAM. When playing an m4v file converted from mp4 (so we're talking maybe a 200MB media file - not an MKV convert or anything in 1080p), I've noticed iTunes balloon to 900+MB of RAM. If I quit the application and open it again, it immediately snatches up that 250MB or so of RAM, then balloons within minutes.
So while I expect iTunes to consume RAM, as it is a very resource-heavy and busy media center hub, I am surprised by the amount of RAM being consumed here and was wondering if anyone might be able to clarify whether I should consider this a "problem" or just iTunes being iTunes; and if it isn't a problem, are there still any suggestions toward how I could minimize RAM consumption? I realize that I have RAM to spare, but when I get into video conversions, music playback, and work on this computer (all the while my wife is streaming a video across the house on an Apple TV), I do want to make sure I'm not wasting memory on an application that might be ballooning unnecessarily (it is, after all, 6X the consumption of the next app in line).
Just for those who might be wondering what I've already tried, I've worked on several quick fix ideas to help remedy the situation (and hoped they would fix the other issues I've experienced with iTunes 10.6): I've rebuilt the library by opening a new library and importing from my previous iTunes LIbrary file; I've created a new library, dragged any media to it, and tried to play it; I've run iTunes in 32-bit mode. None of these has resolved the issue. I have also attempted to run these files from a new user account (with a new library or with the existing library), and have tried them from an external troubleshooting drive which is also running Lion 10.7.3 and iTunes 10.6.1.
Any ideas, suggestions, or recommendations anyone could provide to aid with this problem? While it's not crippling, it does cause some headaches as other applications begin fighting for memory. I also wonder if the amount of RAM it's consuming might be the source of some other playback and unresponsiveness issues I've experienced.
Thanks for any suggestions; I really appreciate your time.

I have resolved my issue with iTunes' RAM consumption and wanted to post the solution for anyone who might be experiencing similar symptoms. It was really quite simple to fix, I just didn't see it for what it was:
iTunes Match was causing iTunes to utilize significant amounts of RAM to queue, refresh, or sync my iTunes Match database.
iTunes Match - which also forces Genius Mode to be on (something that used to cause my iTunes 10.5 to freeze and balloon in RAM usage before I turned it off) - would regularly attempt to refresh my database of 21,000 matched songs (none of which were stored on the computer - just in the cloud) and when it would attempt to update or refresh that library, the program would stop responding. The RAM ballooning I saw when the application launched would start to climb during that unresponsive period, when iTunes was attempting to pack more and more power into the Match check to get it to power through.
So, the simple solution was this: Turn iTunes Match off and iTunes quits freezing, and its RAM usage after 24 hours of uptime is about 130MB.
Now, that of course completely eliminates the usefulness of iTunes Match since the music is no longer accessible on this machine in this iTunes Library. So how to restore its usefulness without recreating the problem? Slightly more aggravating, but still working right: I created a separate, fresh new library and named it iTunes Match. When I need music, I hold option when selecting the iTunes app and select my Match Library, which has NOTHING else in it but iTunes Match. When I'm done with the music, I switch back to my 24/7 media streaming library that has my 2TB of TV Shows & Movies (and device sync relationships) in it.
It doesn't seem like iTunes Match causes freezing and RAM ballooning all by itself, it just seems like in a library that's also full of other stuff, it's the final straw that kills the performance. Split the libraries up and things seem to work really well in both.
Not a perfect solution, but until the next release of iTunes, this may be the best bet. I hope this helps someone else out there, but it at least cleared up my issue. Thanks for reading.

Spaces and iTunes quitting issues

I have given iTunes it's own "Space"-- and when I choose to quit the application outside of the iTunes Space, the program will refuse to quit.
Once I move over to that space it will shut down.
I am using iTunes 7.5 (19) and Mac OS X 10.5.1
I don't believe there is a fix, but am just hoping someone from Apple takes note.

These forums aren't monitored by Apple. To send iTunes feedback select the "Provide iTunes Feedback" menu item from the "iTunes" menu in iTunes.

Want to erase and install & reinstall iTunes libraries and some documents

My iMac G4 Flat Panel is 9gb shy of being totally full and performance really suffers as a result. I want to erase the drive and install Leopard (I just bought a new disk).
What is the best way(s)/procedures to backup my iTunes libraries and some documents so that I can reinstall them on the newly formatted drive?
After paying for the Leopard disk, I don't want to buy any other programs to do the backup. I have been backing up the drive to an external using Backup.

Steven,
Backup is a fine application, but it typically targets specific items to be backed up. Meaning, that it is not necessarily entirely comprehensive. At least not in the context of migrating from one installation to another.
One of the concepts present in OS X is the idea that everything that makes your account "yours," all of your data, settings, history, etc., is entirely contained within your HOME folder. By moving that HOME folder into any new installation, you essentially transplant your entire experience as a user into the new location. In many cases, this works so well that, if someone did it behind your back while "swapping" computers with you, you would never know the difference. That's how it works, in theory.
In practice, there are usually some minor things that pop up in such a transfer, but these are all minor in the extreme. One might end up with a "question mark" or two in one's Dock, resulting from the absence of a linked application in the new installation. The question mark can be removed, or the application in question can be installed, so these things are easy enough to fix.
Your situation is complicated somewhat by the fact that you want to "whittle down" what you restore to the new installation. The assumption I make, based on your posts, is that you have only the one account, and your single HOME folder contains enough data to consume most of your disk space. OK, you can handle this several ways...
You could cover all bases by making one complete backup of your HOME folder as it is now, then begin "whittling down" what you have now before wiping your drive and reinstalling. This would give you the opportunity to reduce your disk space consumption while still working within your HOME folder; testing what you do, as it were, and with the knowledge that your deletions are not irreversible. When you find the right balance between what you can delete and what you must keep, you can make an additional backup of your reduced HOME folder (provided you have enough space on your external drive).
Or, you could make a complete backup of your HOME folder, as it exists now, then go ahead and format/reinstall. You would then have to decide what you will move from the backup into your new account. Part of this process is knowing just where to place transferred items for everything to work properly. As far as simple files are concerned, it wouldn't make any difference where you place them. Items contained in libraries, however, might be quite complicated to move, unless you simply moved the entire libraries in question. In these cases, the libraries themselves must be transferred to the correct locations. It's not an insurmountable problem, but it does complicate matters a bit.
Finally, you could backup and restore the HOME folder as it currently exists. Typically, the process of formatting and reinstalling, then restoring user data, results in a more compact installation. Over time, any installation accrues some fragmented free space, and this effectively reduces the storage capacity of a volume. As much as or more than 10% of the size of the volume can be recovered this way. In any case, your new installation will be smaller than the old to some degree, even with all of your user data restored. Once you get to this point, you could begin reducing the amount of data you have stored, just as in option #1 above, and again safe in the knowledge that nothing you delete is irrecoverable.
rsync is powerful. While it is easy to use, it has many options and is therefore complex to learn. Its "man pages" might be considered daunting. I could provide a copy and paste command for you to run which would make a complete backup of your HOME folder, provided I knew the path to a destination. The exact name of your external drive, along with any nested folders therein you might want to use as a destination, would suffice.
If you want to read more about rsync yourself, open Terminal and type "man rsync," then press <RETURN>. The "man" application will scroll line by line by using the arrow keys, and page by page by pressing the spacebar. Press "q" to quit the man application.
Scott
