RAM sizing for low mailbox count but large mailbox sizes?

The server will house about 50 mailboxes between 20-50GB. The remaining 50 users are around 2+GB Any best practices for sizing memory when the mailbox count is low but the size of the mailboxes are large?

Introducing Lowarch - Arch for low-end systems

Some of you might remember that I mentioned my plans of making an Arch install cd for low end systems. I've come quite far with this project now.
First, I must say that it was a lot harder than I first expected. So I can say I have learned a lot in the process.
Second, before I start ramblig about where I am in the process, I'll just outline what the plan is:
The best Linux distribution is Arch Linux, because of it's speed, simplicity and elegance in design. I often get hold of some old laptops which are too old for Arch (i586 normally, but also i486). I have tried a lot of distros made for low end systems, but I always end up thinking, ah how wonderful it would have been to have Arch on this. It would have been the perfect distro for this machine.
And the more I thought about it, I realised that even though Arch is perfect for super modern systems, it would be even more perfect for old systems, because of it's speed and simplicity, and not least the choice of packages.
Some have started projects to port Arch to i586. I don't think that is the best solution. A lot of Arch isn't really useful on these machines. Therefore I decided to make a new distro based on Arch, where the main difference is the choice of packages. You don't want to run a video editor on a i586. For now I've called the distro Lowarch.
Here's what I have done so far:
1st try:
Oh, I just change the compiler flags to i486 in /etc/makepkg.conf and start compiling all the packages. That worked great. Almost everything in base compiled fine. Until I started to notice the strange i686's coming up in all the ./configure outputs, and when I tried to install some of it on my i586, a lot of Illegal instruction messages came up.
After doing some research, I understood that some programs make static links to libraries, all of which, of course, are i686 coded on my system. I realised I needed to do this differently. Of course I didn't want to do all the compiling on a 486 machine.
2nd try:
I made a Cross Linux From Scratch system, compiled for i486. Even that I had to make twice, for a lot of programs check what processor they are running on and compile for that. So the second time I used a so-called uname-hack. A small kernel module which makes the kernel report that it's running on an i486 machine.
When I had a basic build system, I compiled pacman, and started to build packages. This time I had to take care of the order for dependencies to work out. First kernel-headers, glibc, etc. I installed one package at a time into an empty directory with the pacman -r option.
After having the base system compiled, I booted it, and (using the uname-hack still) continued to compile the other packages in current, and the ones that I wanted from extra.
It was really hard, since a lot of packages just don't compile with recent glibc and gcc. I have learned a lot about writing small patches just to make gcc happy or take away symbols not used anymore etc. The dependencies in the pkgbuilds are not always correct when it comes to building packages. Sometimes, and this is the most frustrating, packages seems to build correctly, but because some library wasn't installed or whatever, a few files are missing from the package, and I have no way to know, untill something goes wrong. Often this wrong is a package not compiling because include files are missing.
Another problem was to make an installer. I decided I just wanted a simple installer, like Arch has. So I compiled busybox and made an almost exact copy of the 0.7.2 install cd, just compiled for i486, and with my package selection on it.
What's left to do:
1. Look more closely at the package selection. If there are people who are interested in this we can have some nice discussions about this. There are a lot of packages I just don't know what is for, and therefore I don't dare take them away.
2. Clean up the PKGBUILDs, e.g take away references it the i686 and 64bit arch.
3. Compile the whole set of packages again, just in case.
4. Releasing it.
I've set up a wordpress page at lowarch.linuxophic.org, which is empty now, but where I'll put out a link to the iso when it's ready.

Yes, I think it would be smart to check out the PKGBUILD once in a while and see if they are still able to build packages. It seems this is only done when new releases arrive.
The thing about old programs not compiling with newer glibc and gcc or other libraries is unavoidable, and there's an unending stream of patches to address this issue. If a package hasn't had a release for a year, it's quite common that a change in a library it depends on will break the compilation. When or if new releases come, they should usually fix this.
Of course, PKGBUILDs of current packages should work with a current system, not with a system from last year, if their supposed to be of any use. But it's a huge job to keep this up to date at all times, and you need some programming skills to do it, and I would rather have the devs focus on more important things, like updating packages and making everything work even better.

Database Memory sizing for BI Beans

We need to make a RAM sizing for a production enviroment for 200 users, how can i do it?
Thanks in advanced,
HABO

This needs to be broken down into two areas and by hardware and software requirements:
1) Database - the OLAP forum would be the best place to ask about specific requirements for the OLAP option. There is guidance on parameter settings for the OLAP option in the installation guide. In terms of hardware to support your proposed user community. In the documentation pack you might want to review the Data Warehouse and Performance Tuning guides.
2) Middle-tier/iAS - Oracle has an internal only utility that can be used to predict hardware requirements for a middle-tier server. Your account manage should be able to help you with this. In terms of tuning, please refer to the Oracle Application Server Performance Guide.
Hope this helps

Cyrus max mailbox size? (Not quota)

Hi,
Hopefully a quick question... I searched on the forums and web but to no avail, everything talked about quota.
I just wanted to know if there is a suggested limit for individual mailbox sizes in Cyrus (Theoretical or definitive)? What about the overall database size, any suggested or definitive limits there?
This is not a space concern (Mail servers raid6 has a good 1TB left). I mainly just want to know if there is a point where performance begins to suffer and / or if chance of database / mailbox corruption increases at a certain level. This is on a 10.5.6 xServe 8 core 4GB RAM connected to a promise raid6.
Naturally a reconstruct takes longer on a larger mbox and so on of course. Thanks in advance for any answers!

Hey Alex,
Quick followup if I may. For clarification sake. Do you mean per "user" or per "mailbox". IE: I have a user with 1.3GB in "inbox" for example but say they also have 700MB in a mailbox they created on the same IMAP account called "archive" and then another called "personal" at 300MB. Have I eclipsed the the best practice 2GB at this point or is it a per folder basis?
For example when I review these in cyrus admin they are of course separate but when viewing the user backup records as a whole through mailbfr, it combines all folders per user account as expected. Just wondering which value to go off.
Thanks for your continued help!

How do I setup multiple users to use one source but manage playlists separately? For example, play counts are specific to each user.

Hi,
Thank you for posting in Windows Server Forum.
Here adding to the words of “Tim”, a forwarder is a DNS server on a network used to forward DNS queries for external DNS names to DNS servers outside of that network. You can also forward queries according to specific domain names using conditional forwarders.
A DNS server on a network is designated as a forwarder by having the other DNS servers in the network forward the queries they cannot resolve locally to that DNS server. You can refer information regarding forwarders and how to configure from beneath link.

Unread messages count is wont for Smart Mailbox

Has anyone else noticed that a smart mailbox has a non-zero unread message count but as soon as it is clicked on the count is reset to zero? Zero is correct because all of the messages have been read. I've tried rebuilding the inbox but it hasn't helped. I also recreated the smart mailbox but that didn't help either. Sounds like a bug to me but I wonder if others have experienced it. I am using Mail Tags so that is a possible complication.

Same problem here with Yahoo mail. Sometimes it works, sometimes it doesn't. I have looked at Yahoo mail from all folders in my phone (running 7.0.3 now), as well as in a browser, looked at Inbox (empty), all Trash, Sent, etc. folders and they're completely empty on Yahoo servers.
I thought that 7.0.3 had initially cleared up this issue but it has reappeared, and I don't know how to fix it.

I don't see any DDR3L on the page for the RAM that would fit your model -> http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3_133 3MHz_SDRAM.
But the answer is that it doesn't really matter - just make certain to get 1333MHz.

1 month ago I changed batteries to my keyboard.yesterday appeard msg for low battery again. I try to take of the old ones but I realized that there was battery liquid dry in there. Now my keyboard is dead... Do anyone knows what to do... I need a new ?

If your batteries leaked and possibly eroded teh contacts the best you can do it to attempt to remove all the fluid and clean the contacts. If the keyboard still does not work after a thorough cleaning yes it will need to be replaced. A new wireless keyboard is about $59 from OWC or you may want to look online for a used one, sometimes OWC (www.macsales.com) has them used. Other sources are Apple of course, Amazon, and any Apple reseller.

Hi Quinn7,
Was the one which you were upgrading from a Educational version? If so, that might be related. I'd recommend reaching out to our support for assistance. I think there is a link for chat or phone on the bottom of the plans page: Creative Cloud pricing and membership plans | Adobe Creative Cloud

IO fails working for low frequency, but work well for higher frequency

On our customized VU440 board, we did a IO performance test for each bank and found a strange problem, in the design,we send out 24bits Pseudo random data and loop back this data to the same bank with our testing board, on which the pins for tx and rx are only connected in short circuit, one differential clock is transfered to single-ended global clock in the design, using IBUFDS+BUFG to provide the global clock for tx module and rx module.
howeve, we use vivado debug tool to check the data looped back, only found when the clock is 200MHz around, the data is correct, but if fails to get correct data when the clock is much lower, for example, 10MHz ~100MHz. And from the waveform we got, we identified the status for some pin was un-normal when the data bus failed to get correct data.
we have found the problematic IO pins, but did not know why the problem come out, normally, we think it's normal for the IO pins fail to work when the frequency is too high, but in our case, the issue is on the contrary, we don't understand why it works for some higher frequency but fail to run when it's much lower.
we now try to check our PCB also, but have no clue at present.
Some guys have any idea or suggestion to check for the reason?
thx~

Hi,
What is the IO standard that you selected for the TX and the RX. How long is the loopback cable?
Do you have proper terminations on the board? Because in general, all IO Standards need some terminations which are mentioned in the respective SelectIO user Guide for that device. Please check that.

Very large file 1.6 GB..sports program for school. lots of photos, template where media spots saved and dropped photos in..trying to get it to printer swho says its too large but when reduces size loses all quality...HELP??

Please help...large file my sons Athletic program. Had noto problem with Quality last year..this new printer said file is too large..too many layers, can I FLATTEN..He reduced size and photos look awful. It is 81 pages. Have to have complete before next friday!! Help anyone??

At that size it sounds like you have inserted lots of photos at too large a size and resolution.
Especially for a year book style project, first determine your image sizes and crop and fix the resolution to 300 dpi, then drag them into the publication. Pages does not use external references to files and rapidly grows to quite large size unless you trim and size your images before placement.

How To Get Deleted Item Count and Associated Item Count And LastLogOn and LogOff Time For A Mailbox In Exchange Using EWS

Using Powershell cmdlet i get all the details..But i want to get these Details by using EWS Managed Api.Is It Possible to do???
Powershell Cmdlet,
Get-MailboxStatistics -Identity Username, Using this cmdlets all the details will get displayed.
DeletedItemCount:5 //Here how this count comes.In My OutlookWebApp the deleteditems folder contains 13 items in it..But the count shows only 5.
TotalDeletedItemSize:5.465 Kb//Even this value too does not match with DeletedItems Folder size in owa.
AssociatedItemCount:12
LastLogOnTime:11/11/11 12:43PM
LastLogOff Time:11/11/11 2:43PM
In EWS,
By Looping through all folders i can get the total item count and total item size.Even i can get deleteditems count .But that value does not match With the powershell value.Even the TotalDeletedItemSize
Doesnt match.
Using EWS Managed Api ,Looping through folders i can get ItemCount,TotalitemSize,(DeletedItems,TotalDeleteditemSize(These TwoValues Does not match with values comes from powershell))
Now how to get the Associated item count and lastlogoff and logon time using EWS managed Api.Is it Possible???
And even y the deleteditems count and size values varies between EWS and powershell.

What happens if you execute the below code?
Get-MailboxFolderStatistics [email protected] | where {$_.FolderPath -like "/Deleted Items"}
Refer this blog. You may get some dice
