EMail attachment size, what is your limit???

MIME encoding sucks :lol:
A email with a 35meg .zip attachment comes in as 49.6megs (using the smtp logs)
I've got a non-tech CTO that want to accept 50meg attachments. It seems to be working but sometimes the SOPHOS AV engine crapsout and the email ends up in the quarantine.
For business to business email what is a reasonable size limit?

MIME encoding doesn't suck! What sucks is the fact that we still need to do it. The fact that SMTP is still a 7-bit channel is annoying.
I don't administer an Exchange server myself, but our Exchange admins explained to me that Exchange does size limiting based on the native (aka decoded) size of the attachments. The FreeBSD/qmail server I run enforces the maximum message size based on the wire size, i.e. base64-encoded for anything binary. Since base64 is a 6-in-8 encoding, that increases the object size by 33%. In order to reconcile the size limits on these two systems, the Exchange limit is set to 30 MB and the qmail limit is set to 40 MB. That's usually enough for the PHBs to mail around their humongous PowerPoint presentations.
I haven't bothered messing with the message size limits on our IronPorts, since our back end servers enforce their own limits.

What's YOUR Idea of an "Ideally Organized HD?

What's YOUR Idea of an "Ideally Organized HD?"
I've been giving this a lot of thought lately. Whereas it is obvious that OSX organizes your hard drive better than anything on Windoze, especially when you consider the power derived from using Spotlight, I have been wondering exactly WHAT, WHAT does an Ideally Organized Hard Drive look like? What are it's properties? I don't mean how it should look specifically to YOU, the single user. I mean what does an ideally organized Hard Drive look like to everyone running OSX? (which is everyone). What are some of the components of a ideally organized hard drive? What does it look like/feel like? Not necessarily in order of importance, I'll start this one off:
An Ideally Organized Hard Drive Has These Properties (feel free to add your ideas):
1) All the music, documents, apps, pictures and movies go into their designated locations, just for starters. You may even want to create another main Category such as I did, and call it "All Talk & Sound FX". Here's where I stick my voice, and talk radio, and verbal jokes etc. for example.
2) There are NO identical (duplicate) files, but the thorough and profuse use of Alias files are implemented. {{{if you have duplicates, and you update the one, you necessarily have to update the other, otherwise, you don't have duplicates anymore, right? But if you use an Alias, no matter which file, original or Alias, that you update, BOTH files are updated.}}}
3) The HD is organized for EASY Backup on a daily basis: Everything new gets placed into an "Everything New" file (call it what you want) on the Desktop, then this one folder is backed up daily, saved onto an external HD, then loaded back and now actually saved onto the HD as new stuff just once a week (in accordance to #1); this is the outcome from doing a Restore from this backed-up "Everything New" folder. Everything goes into this "Everything New" folder on a daily basis; however, Applications are installed immediately whereas everything else just gets popped into the "Everything New" folder for holding.
4) Many files are annotated in the Get Info Window with easy to find key words and comments. Spotlight will do the rest my friends!
5) A DMG of the HD (a perfect Clone which is achieved using your Tiger Disk--Disk Utility) is done on a weekly basis (heck, all you have to do is launch the software at night, go to bed, have an automatic shutdown on your Mac for about 3.5 hours later (for a 23GB DMG Disk Image)). {{Note that a Restore from the "Everything New" folder must be done first!, prior to making the DMG}} When this Disk Image is made, it will have All of your Preferences, All of your newly installed applications, All of your Bookmarks, All of your new additions to iCal, All of your new Addresses, EVERYTHING, and therefore these specific folders do NOT have to be backed up **separately** by using this process as I describe.
Once a week you will Restore from this DMG (which takes an hour if you have previously verified/mounted this image), then delete the week-old Backup of the "Everything Folder", because your HD now now has all these files added to it (remember, the key here is to do a Restore from the "Everything New" folder first, before you made the most recent DMG). You can now also delete any old Disk Images that you want, because you will be making more! (I always keep 2 or 3 on hand). You can now also delete any old "Everything New" backups from your External, because you will be making more of these backups as well!
6) Your Hard Drive should utilize the copious amount of custom icons, in order to quickly spot and identify files/folders.
7) You have created shortcuts (Alias') on the HD, which point to spots on the External HD, (which is not only used for Backup as recently described) to facilitate the transfer of large files (example: AIFF's) to/from the external HD. My External HD has a working "Powerbook" folder where these files are saved to, keeping my internal HD at a bare minimum of growing size, yet the files are easily uploaded/downloaded between the external and internal, and viewed, when the External is attached (of course) to the internal.
8) The hard drive lacks any sensitive material whatsoever, i.e. passwords are kept on an external hard drive, and new ones are backed up daily to the Everything New folder. Using a free program such as Password Vault also strengthens this area of security and organization. If the Passwords are kept to an external location, and yet are easily accessed by an Alias, then they are 100% safe to reside on the External, since the External would have to be attached in order for the passwords to be read.
9) Maintenance is run routinely on the HD, using a program such as Onyx, especially before and after the disk image process. You can also schedule Onyx to run the Apple maintenance scripts automatically, when you are asleep. Also part of this maintenance would be running a program such as Disk Warrior, before and after the disk image process. Onyx and Disk Warrior go hand in hand, and although you will not "see" (visually) HOW your HD has been organized more efficiently, you will experience the benefits of using Disk Warrior (faster/more responsive), which organized your HD Directory automatically.
10) Another nice little Utility is SpeedTools, which has a great program for Defraging files. Yes, I've found that Disk Defrag does work. Point #10 does nothing for "organizing", however I make this point because Disk Defrag does indeed help your HD to run more efficiently (thus faster).
*** Ohh by the way, maybe I'm saying the following as a joke, maybe I'm not. But if you follow my suggestions above, you wouldn't be so paranoid about downloading the latest update to Tiger (or Leopard when that comes out) because the old "Archive & Install" option becomes obsolete. If you run into trouble NOW, using my methods, you now have the peace of knowing that you have a perfectly Cloned Disk Image of your valuable, ideally organized Mac HD, residing on an external drive and just waiting to be called into action! ***
Finally, please note that I am not telling you how to organize your hard drive, I am only suggesting this as one way to do it, and the way that I do it. If you have something totally different from this, but it works for you, please post that. If you want to add to what I've said, go right ahead! But if you don't agree with something I've said, then by all means offer your own suggestion and be civil about it! Thanks!

You and everyone else that takes the time to read, and understand what I said, and can benefit from this, is WELCOME! ; )
By the way, I forgot to mention. I use "Micon" a little terrific freeware program (from VersionTracker) to make (initialize) my custom icons. I also use Graphic Converter to make my own original icons of anything I like. Don't underestimate the value in making your own custom icons-- they really stand out from the "standard old blue".

What is the actual size of an (empty) varray in a record?

what is the actual size occupied by an (empty) varray in a record?
For example, if I create my table defined as:
create or replace type XXX as object (
myRefs VARRAY(10) of REF(yyy)
create table YYY as XXX;
what is the actual size of the record of type XXX when 'myRefs' is empty? For some reason, select data_length from all_tab_cols where table_name = YYY seems always to return 3K as the length of column myrefs.... is that correct? If not, what is the correct size?

A tad late here...
Storage sizes of REF attributes are described here:
[Design Considerations for REFs - Storage Size of REFs|http://download.oracle.com/docs/cd/E11882_01/appdev.112/e11822/adobjdes.htm#i452226]
The size of your REF attribute (or element, in your case) will depend on whether it is primary key-based or system-generated, whether it is scoped or not, and whether it carries with it a rowid hint. The overall size of your VARRAY attribute as it grows will also depend on whether you allow null REF values or not, but essentially will be the size of your REF multiplied times the number of elements in your VARRAY (plus a small, constant amount of storage for internal housekeeping, both for the attribute and for each element).
You could try the VSIZE function as an appromixation...

What is the maximum size for mailbox per user (Exchange 2007)

Hello,
I'd like to know:
What is the maximum size per mailbox, and is it not recommended to exceed 3 GB and about the items how many is the maximum per folder (inbox, .. )
I've Exchange 2007 SP2, Outlook 2007 and 2010.
Thank you.

Hi
There is no size limit on mailboxes up to the maximum size of your database. I normally recommend 2GB mailbox limits if you have some form of archiving in place. If you have no archiving in place then the limit should be set at the amount of
data people need to keep - it is not a good idea for people to store mail in PST files because there is a limit on their mailbox.
See this article for item count recommendations:
http://support.microsoft.com/kb/905803
Also you need to upgrade your Exchange 2007 server to SP3 ... SP2 has been out of support for nearly 3 years already:

TS3276 What's the maximum size of an email to be sent by Apple's Mail program?

What is the maximum size of an email sent in the Apple Mail program? Is 2.9 MB too large?

susanzimm wrote:
Is 2.9 MB too large?
No, in terms of Mail.app. As WZZZ said, this limit is set by your ISP.
Yes, in terms of netiquette. Google it. Any file > 1MB is, IMHO, too big for e-mail. Nowadays, this rule may be more relaxed, because more people have broadband. You should check with your intended recipient.

In the current scenario which I need to design , the request XML file could be up to 24 MB.
Also if you could comment on which would be the best to use as the sender side - SOAP or File Adapter
when the request message/file is of such size?

hi,
>What is the maximum size of request message it can handle efficiently.
it totally depends on your hardware and flow design inside XI/PI
>In the current scenario which I need to design , the request XML file could be up to 24 MB.
this size is not a lot for a "normal" XI machine but it also depends on the
volume of those messages - that is if you need to send
one message like that per day or 1000 per half an hour...
>Also if you could comment on which would be the best to use as the sender side - SOAP or File Adapter
when the request message/file is of such size?
SAP's general recommendation is to use messages around 5mb
but it heavily depends on other factors so don't threat it as a must

What is the max size of a zip file with the JDK1.5 ?

Hello everybody,
I'm a french student and for a project, I need to create a zip file, but I don't know in advance the number and the size of files to include in my zip.
I wish to know if someone have the answer to my question : what is the max size of a zip file with the JDK1.5 ? I believe that with the JDK1.3, the limit size of a zip was about 2Go, wasn't ?
Thank you for all answer !
Good day !
PS : sorry for my very poor english ;-)

Here is all I have found for the moment :
...Okay, what about my suggestion of creating your own 10GB file?
Try this:import java.io.File;
import java.io.RandomAccessFile;
import java.nio.ByteBuffer;
import java.nio.channels.FileChannel;
import java.util.Random;
class Main {
    public static void main(String[] args) {
        long start = System.currentTimeMillis();
        int mbs = 1024;
        writeFile("E:/Temp/data/1GB.dat", mbs);
        long end = System.currentTimeMillis();
        System.out.println("Done writing "+mbs+" MB's to disk in "+
                ((end-start)/1000)+" seconds.");
    private static void writeFile(String fileName, int numMegaBytes) {
        try {
            int numBytes = numMegaBytes*1024*1024;
            File file = new File(fileName);
            FileChannel rwChannel =
                    new RandomAccessFile(file, "rw").getChannel();
            ByteBuffer buffer = rwChannel.map(
                    FileChannel.MapMode.READ_WRITE, 0, numBytes);
            Random rand = new Random();
            for(int i = 1; i <= numMegaBytes; i++) {
                for(int j = 1; j <= 1024; j++) {
                    byte[] bytes = new byte[1024];
                    rand.nextBytes(bytes);
                    buffer.put(bytes);
            rwChannel.close();
        } catch(Exception e) {
            e.printStackTrace();
}On my machine it took me 43 seconds to create a 1GB file, so it shouldn't take too long to create your own 10GB. Then try zipping that file.
Good luck.

What is the maximum size limit for a KM document to be uploaded?

Hi,
1. I have a requirement, wherein the user wants to upload a document which is more than 448MB in KM.
I am not sure what is the maximum limit that standard SAP provides by default, which I can advice the user at the first place.
2. what if we want to increase the max limit of the size?Where do we do that, can you suggest me the path for the same?
Thanks in advance.

Hello,
CM Repository in DB Mode:
If there is a large number of write requests in your CM usage scenario, set up the CM repository in database mode. Since all documents are stored in the database, this avoids unintentional
external manipulation of the data.
CM Repository in FSDB Mode:
In this mode, the file system is predominant. If files are removed from or added to the file system, the database is updated automatically.
If you mainly have read requests, choose a mode in which content is stored in the file system. If this is the case, make sure that access to the relevant part of the file system is denied or
restricted to other applications.
What is the maximum size of the document that we can upload in a CM (DB) and CM (FSDB) without compromising the performance ?
There are the following restrictions for the databases used:
· Maximum number of resources (folders, documents) in a repository instance
   FSDB: No restriction (possibly limited by file system restrictions)
   DBFS and DB: 2,147,483,648
· Maximum size of an individual resource:
   FSDB: No restriction (possibly limited by file system restrictions)
   DBFS: 8 exabytes (MS SQL Server 2000), 2 GB (Oracle)
   DB: 2 GB
Maximum length of large property values (string type):2,147,583,647 byte
What is the impact on the performance of Knowledge Management Platform and on Portal Platform when there are large number of documents that are in sizes somewhere from 100 MB to 500 MB or more.
The performance of the KM and Portal platform is dependent on the type of activity the user is trying to perform. That is a heavy number of retrievals of the large documents stored in the repository for
read/write mode decreases the performance of the patform. Searching and indexing in the documents will also take a propertionate amount of time.
For details, please refer to,
http://help.sap.com, Goto "KM Platform" and then,
Knowledge Management Platform   > Administration Guide
System Administration   > System Configuration
Content Management Configuration   > Repositories and Repository
Managers    > Internal Repositories   > CM Repository Manager
Technically speaking the VM has a restriction according to plattform. W2k is somewhere around 1,2G and Solaris, I believe, 4G.
Say for instance I was on a W2k box I allotted 500+ for my J2EE Engine that would leave me with the possiblity to upload close to 600mb documents max.
See if the attached documents (610134, 634689, 552522) can provide you some guidance for setting your VM to meet your needs.

What is theoptimal file size for stills, and dpi?

what is theoptimal file size for stills, and dpi?

In video dpi is not relevent. What counts in video is pixels. In FCP most recommendations I have seen is to size your stills so they have no more than 3 times the pixels in your project aspect ratio. For example if your project is 1280x720 then stills should be no more than 3 times the 1280x720. This allows you to crop the stills and still have good resolution. If no cropping is anticipated then they could be the same size as your project.

HT201342 what is the max size of attachment that possible to send with icloud email?

what is the max size of attachment that possible to send with icloud email?

Welcome to the Apple Community.
There isn't an attachment size limit as such, the limit applies to the entire message including all attachments, which is 20 MB.
if you are using a mail application to send emails (ie not via a web browser) you may be subject to smaller limits imposed by your own ISP.

What's your favorite of styling hyperlinks?

Hi,
what's your favorite way of styling hyperlinks?
Right now I've colored mine C=100 M=100 Y=0 Y=0 and made them underlined. I feel the underlining is a bit too harsh on my overall design. Then again if I don't underline them, how are people suppose to know they're links?
Spelling out URLs is just not an option. Unless I use TinyURL? They say their links will last forever but who knows for sure?

That is a question about cultural expectations -- I can't answer that confidently. The check mark that so often is used in US software to signal 'OK' (as in the spelling checking function where I edit this message) signals 'Error' to me -- and when it is shown in green (as Borland Software did at one point, and as Adobe does here) it signals both 'Error' and 'OK', and produces a kind of 'pulling-both-ways' effect that isn't too pleasant -- to me. I'm not sure I can come up with something that works for you.
The dialog bubbles may work -- though to me the carry overtones of a footnote or an endnote. But they pretty clearly seem to signal 'more info elsewhere', and that's definitely a step in the right direction.
I would be looking for something like a bent arrow -- perhaps Unicode U+21AA (↪), or perhaps something similar with a double arrow (Unicode U+21D2, ⇒), except I'd like it to have a similar curve at the left, half suggesting a 'click here to go elsewhere'. (Wingdings 3, character code 0xCA, is close.) But I could probably go for 0x58 in WIngdings 3, rotate it 90 degrees to the right, and perhaps tweak the small box into two smaller boxes of unequal size, suggesting movement.
Or perhaps just something that suggest a 'click here' -- some of the simpler designs in Altemus Bursts, or Altemus Pinwheel or Altemus Stars might work.
I would like something that tempted the reader into testing, and so encourage learning-by-doing. That would be helped by a similar symbol going the other way to indicate the 'back' of a web browser. Arrows help here -- they show a direction. Other designs -- bursts -- won't be a easily understood: what would be a reverse burst?.And what symbol would be used at the target end of the dialog bubbles to suggest 'go back'? (Added: perhaps a quad or square signalling 'end'?)
Arrows seem safer. Even guillemets might work, as long they won't be misread as quotes of some kind. Guillemets in a circle? There are some such glyphs like that in Wingdings. The standard 'fast forward' and 'fast backward' glyphs (in Webdings, say) may also work.
Actually ... this is the kind of problem I'd might want to suggest for a small project for a class for typeface designers.

What is Optimal Block Size?

Given technological improvements in the past several years to hardware, should we stick with block size of 8 to 100 kb per DBAG? I would think we can go higher.
But how high is very high?
We designing a database and if I stick with Acc (D) and Time (D) I will have around 700k of block size and this may grow in the future if more accounts are added.
What is your recommendation? Pros and cons with your recommendation.
Server Config:
OS: Sun Solaris 10
RAM: 32 GB
CPUs: 4
Thanks in advance for your ideas and answers!

If you're in a Planning environment, you really have to benchmark form performance when Accounts and Time are the axes if they're not dense -- sometimes pulling multiple blocks per form is okay, sometimes not. And in turn that performance drives what is in the block and thus block size.
The "right" answer is based on perspective -- is it calc time or retrieve time that is the performance measure, or both. Where you fall in that multidimensional continum determines block size. This would be the art part of sizing.
