How much RAM needed for the DB box

Hi,
Can someone share with me the technical way to do calculation of how much of RAM needed for a new Linux box with estimation of 500 users. I hope this calculation can also allow me to breakdown how much MEMORY needed for each session.
Please recommend any site that I can refer to if any. TQ.

My project start with Oracle 9i R2 (9206) on Linux (not yet confirm on the platform and etc). Just assume I will use Linux Red Hat Adv Sever latest version.
Hence how many GB of memory for the box is sufficient to handle 500 connections. Pls guide me the formula to derive the calculation. TQ

How much space left for the new System Restore Point(s) creation ??

Sir,
MY LAPTOP : single OS, windows 7 sp1 , ultimate 64 , 2gb ram , 4ghz processor,
kaspersky antivirus full,
total hard disk 150gb, C: 38.9gb, 11.2 gb free space on C: ,
allocation for SR Points for C: 2.73gb (7%)
PROBLEM:(SR Point: System Restore Point)
sir, i am facing a problem of false reporting of the space occupied by a SR Point and so, it is unable to know how much space is left for new SR Points such that the old ones dont get eliminated. Here it is always increasing as the time progresses
    1. I created a SR Point at 9:21PM space occupied being shown 114.97mb
   2. The same SR point showing the space occupied at 9:23pm 115.06mb
   3. After 20 hours it is being shown as 272.36mb !
   4. After sometime ,it would show the space (occupied) even more than the actual allocation for eg.
the full allocation is 2.73gb and it will show 3.1gb occupied by the same single SR Point
      [for solution of the problem i am managing the single SR Point that is by not doing anything that will     trigger the creation of new SR Point(s) ]
SNAP 1 : plz see only one SR Point is there on c:(the other one is system image back up on another drive)
SNAP 2 : Plz see that the space occupied by the same single SR Point is 276.50 mb which was 114.97 mb initially.SORRY , ONLY TWO IMAGES ALLOWED!
HISTORY : since last 6 months the laptop is with me and when I received it, system protection was off. When I made it active , it used to create SR points very frequently for e.g. 10 points in 2 days. So I stopped its automatic creation
2 months back. I disabled both the triggers and the task.
SNAP 3 : both the triggers and task disabled.
NOW
   (.) it makes restore points either manually (by me) or by system in the case of install or updates only,
And I am comfortable with it !
   (.) SR Point restore is full success !
   (.) but the PROBLEM is there !
So,
Is something wrong going to happen to the hard disk ?
Is it a malicious activity ?
Does a full defragmentation for a drive deletes all the restore points on the drive ? (it happens here!)
How should I proceed ?

How much ram is the the ipad air?

Any one know how much ram is in the new Ipad Air?

I saw an article this morning, sorry but can't provide a link, that compared the specs of an iPad 4 with an iPad Air. They are very similar except for the processor speed and the addition of 64 bit addressing. If the speed and 64 bit are important than an upgrade is a good idea but if you feel your iPad 4 is working well you might wait.

How much Ram do I need in a MacBook Pro for Software Engineering?

I plan to buy a new MacBook Pro in the next month for school and hopefully for work. I would like this computer to get me at least 4 years of use. I will be majoring in software engineering. My question is how much ram would I need in a Macbook Pro for software engineering? I am currenty looking at the 15" 2.3ghz base model with 8gb of ram as well as the 15" 2.4ghz base model retina. I really like the retina but its at my max budget. Will the 8gb of ram be enough since it is not upgradable? Any help will be greatly appreciated.

I am currenty looking at the 15" 2.3ghz base model with 8gb of ram
The MB Pro 15" 2.3Ghz with 8GB of RAM should do the trick.
Save your $$$ on the retina and stick to your budget

How Much RAM Do I Need in a Mac Pro to edit together hour-long videos for our church?

We need a new computer to edit video together for our services at church. We broadcast these videos each week, so we use our editing computer quite a bit. We also produce shorter videos for use online and in our services. Looking at moving to a Mac, and I'm not quite sure how much RAM we should purchase in a Mac Pro to avoid long rendering times. Obviously, we need to keep costs as low as possible, but we want something that will work, and last for a while. Thanks!

The fastest 6-core is the "sweet spot" in the lineup. near twice the compute power of the entry model at only 1.5 times the cost.
6GB is fine for "regular" stuff you do on a Mac. Video editing without pain often requires more ... up to as much as 24GB if you can afford it. Apple's prices for this are quite high (like a convenience store). Many folks buy aftermarket RAM from Mac-centric vendors who can tell Users what modules will work in their Mac -- "guaranteed or your money back".
You can run as few as a single RAM module in 2009 and later Macs. So when adding, choose the densest modules you think you might EVER need, to avoid throwing away less-dense modules later.
You also will need at least one drive (preferably two) in addition to the Boot drive. Paging and program access to the boot drive wrecks drive access for User data.
You also need a Backup Drive. Big (but can be really slow).

How much ram do i need for serious video editing?

early 2008 2X2.8 Quad Core Intel Xeon Mac Pro, with 8 GB RAM (8X1GB sticks), 2 @ 1.5 TB hard drives +. Use Final Cut Express for video editing. CS4 for typical daily workflow. How much RAM do i really need to make this a powerhouse video editor?

To make any 'good' recommendations it would be helpful to know what you are editing - DV, SD, HD? That is a big factor in determining specifications.
If you do more than one stream of HD, you will eventually want an external video drive solution from CalDigit, Dulce, Promax, G-RAID, or any of the others you see on the side. And it also depends on what 'flavor' of HD - I doubt your running 1920x1080 uncompressed 10-bit HD off of one drive. an external RAID array might seem like overkill. Generally, the advantages are increased speed (necessary for dealing with uncompressed, high-res footage) and redundancy so you don't lose everything if a single drive dies.
Get AJA System Test to test the speed of your logical drives so you can get an estimate of what you are looking at.
You really DON'T want your OS and programs on the same drive as your media files. It'll cause performance bottlenecks and all kinds of grief.
Those WD 10K 300-600GB drive is perfect for your OS, applications, and swap files. That's ALL that you want to have on it, and add one or even two faster drives as a RAID 0 pair for more speed and space. Get at least one 7200RPM drive for video/graphics/etc.
For your video storage:
The hard drives you mentioned are fine for standard definition video. However, if you want to edit high definition or otherwise have complex / advanced ideas for your projects, you'll need something with higher read rates than just those single drives. This gets pricey, so depending on what you're intending to do, may not be appropriate for you.
During video CAPTURE your hard disks need to be able to write at a speed meeting or exceeding that video data stream. If other programs use the same disk you are saving too, then you have and increased change of missed writes to the drive. That is why they suggest having a seperate set of disks for capture. Not a bad idea.
*Strip size*
should be => 128K, I would use 256K. More importaint is cluster size. The default is 8 K which is good for the operating system plus programs as over 50% of the files are =< than 8K. For large files (is dot VOB can be 1 gig) it is not the best. When you write a large file each clustter contains a pointer to the next cluster that is to be read. I used 32K, or 64 K (at work so not sure) cluster size for my disk containing Pitures and video. The size of the file allocation table is also reduced by using the larger cluster size.
Back in 2007, this is what was recommended:

If you need to convert HD to SD, then you want hardware like the AJA Kona LHi or Kona 3 and those require a Mac Pro. If you go that route, get the fastest Mac Pro you can afford, minimum 8GB RAM, ATI 4870 card.

It isn't that risky. You may be reading hundreds of posts here about problems, but that is out of MILLIONS of iPhones that have been upgraded. Percentage-wise, that means most people have no problem.
However, as with any major change to your system, you should back up everything your iPhone first. Just right-click it in iTunes to get the backup menu. That will be your safe fallback position in case something goes wrong.
I still use an iPhone 3GS. That's older than your iPhone. But iOS 5 works fine on it.

How much ram is needed to make it work the best it can?

i have a g4 and a crappy pc monitor. how much ram can this mac take and how do i get the most out of imovie? thanx a mill!!

i have a g4 … how much ram can this mac take
a G4 swallows up to 1.5GB of RAM...
my experiences: MacOsX under 800MB is no fun...
afaik, iM doesn't profit that much of more'n more RAM,
I think 1GB is a good compromise for your demands&wallet...
a better CPU increases speed dramatically,
G4, G5, dual, quad, Intel... in that order...

Apple does not repair iPhones, but will replace the entire iPhone for a flat fee; see the Repair Pricing section here:
http://www.apple.com/support/iphone/service/faq/
There are independent iPhone repair services that may be able to replace the screen for less. Do a web search for "iPhone repair". Note, though, that if you elect to have the iPhone serviced by an unauthorized shop, all further warranty will be void.

How much RAM do tab groups use (on average)? Do I need to watch out for how many groups I create?

I may have gone overboard in the creation of Tab Groups. I say this because now my system is beginning to act a bit sluggish. I created 7 groups, two of which have 9 or 10 tabs. Should I pull back on the number of groups I create (as well as how many tab are located within each group). That is: How much RAM do tab groups use. How can I calibrate or understand the trade off between these markers and the amount of RAM they use?

You can see the memory usage on the about:memory page.
You can open about: pages via the location bar like you open a website.

How much ram and processing power in my imac will meet my graphic design needs?

Hi,
I'm in the market for a new imac. I'm trying to figure out how much ram I'll need and which processor will be sufficient for my graphic design needs.
I'm gonna need it to be robust enough to have InDesign, Photoshop, and Illustrator open at once along with spotify, safari with many tabs open, and a couple other apps including evernote and game from time to time. Also, I'm gonna be managing a good deal of fonts in font explorer. How much ram and processing power will I need in my imac to keep everything snappy with all these apps going at the same time?
Any advice on this would be much appreciated. Feel free to include any other relevant information you think I should know.
Thanks, Nick

Computers are out of date when you open the box
Ok, getting serious, that iMac should be a viable workhorse for what you want for a good five years, and taht depends on how much ram you put in it, add really fast external storage, and so on.
Didn't throw this in earlier so as to not influence the discussion: my daughter is the senior art director, VP, at a graphics design firm in NYC. Has been in the business for a number of years. When she changed out her Mac at work, bought, or company bought, the 27" iMac model just before the latest, with maxed out CPU/GPU, and storage. They maxed the memory to 32 GB for her, then added a 30" Apple cinema display so she has almost 5' of display in front of her. There is nothing she cannot have open all spread across that display area. She works almost exclusively in print media, occassionally condescends to do web stuff. And has a massive array of RAID drives hanging on it. But that is a setup an individual would be hard pressed to go with.
At home she uses a MacBook Pro with top cpu and display but that is all.
The point, just how massive do you want to go depends on how fast you have to work; in the office where time is money you need tons of horsepower. At home, you scale it to your abilitty to juggle other tasks at the same time.
I think your choices have been great, the discussion has focused on what is important and especially what can and cannot be changed in the future.
Best of luck setting this up.

How much RAM do I need in my new MacBookPro?

I think I need to add more RAM to my MacBook Pro. I've been using it for a couple of months now and I'm tired of running so slow. Things are fine until I have several applications open or whenever I try to run any Adobe Creative Suite programs.
So, my question is: how much RAM should I buy? My 1.83 MacBook Pro has the standard 512 MBs of RAM that came with it. I'd prefer to keep the cost low, so would buying one more 512 MB stick be enough? I am processing 8 Megapixel RAW images in Photoshop. Will 1 MB total be enough?
Also, do I have to have the two slots matched? Can I put a 1GB stick next to my 512 MB stick?
Thanks,
Laura

512+512 is better than 1gb + 0 - because of the ddr2 effect in the same way that 256+256 is better than 512+0, but not better than 512+256
512 + 1gb is better than 512 + 512 because you have more ram which outweighs the performance benefit of the two dimms.
The way to tell is to run activity monitor (from applications), click and hold the dock icon and turn it into a memory pie chart. You'll see how much ram you are using (tip - free ram is the total of free (green) + inactive (blue). If you are only occasionally running right out you might get by with 1gb total.
Also, economically, you'll be able to get a 512 for about $45-50 as people upgrade, whereas the 1gb chip will cost (at the moment - over $100 for generic and $150+ for one that is the same model as Apple supply - these prices do change and right at the moment there is a shortage of DDR2. - If you do want to buy one, post back and I can give you some hints on where and what to look out for). I'm awaiting a machine next week and will be posting 2 512's on craigslist in your(our) region, as do many others who upgrade so it's not a bad way to get ram - from another mbp owner who is upgrading to 2 x 1gb - and it's normally been tested for a few days.
Also, not a bad idea to have a look to see which chip Apple have put in their already and post back.
Best of luck.

How much RAM do I need to run FCP effectively?

As you can see below, I have an iMac 2.1 Ghz 20 in. (isight) w/ 512 MB of RAM, and I also have FCP, but have been experiencing some playaback framerate issues. So I have decided to upgrade my RAM to either 1 GB, 1.5 GB, or 2.5 GB... My question is how much RAM do you have and how well does it run. I know 2.5 GB's would be the ideal amount, but if I only need 1.5 GB then I would prefer to go with that and use the extra cash for new speakers.
Thanks, and I posted this over at the Final Cut Express board on accident so if any of you feel you have read this before... thats why.

Get an external hard drive - Firewire 400 min/ firewire 800 if your machine will support it.
Having media and the os on the same disk is a recipe for disaster.

How much RAM for ONE App & does OS X limit allocation?

Hello all,
This question concerns how much RAM I realistically need to run ONE application to it's fullest. I mainly use ProToolsLE 7.3, but sometimes use LogicPro 8 and Final Cut Express 4, again, only one running at a time. I've read on the ProTools forum that Windows (yuck) limits the amount of RAM that can be allocated for 1 application. Does Mac OS 10.4 or 10.5 do this?
Right now I have the stock 1GB (2 x 512MB). I plan on pulling it and installing a matched quad of either 1GB sticks (4GB total) -OR- 2GB sticks (8GB total). I understand that matched quads in slots 1/2 of both risers is optimum for the early Mac Pros.
The ProTools forum isn't helping much. A ProTools support person said that starting with 4GB will be good to start and that they test their systems with 4GB installed. What did they mean by "good to start"? Will it increase jumping to 8GB or is 4GB all ProTools can really use?
Another guy on there said "keep in mind that to use 4GB of ram - you'd need a 64bit Operating system (not supported by pro-tools) or on a MAC PAE support enabled, which depending on your hardware may not be a great move." I dont know what that means! Mac OS 10.5 IS a 64bit OS, right? And ProTools 7.4 NEEDS OS 10.5 to run....even if it is only a 32bit app. (though right now I am running PT 7.3 on OS 10.4....not sure if 10.4 is 64bit)
A quad set of 1GB is under $170 and a quad set of 2GB is under $270. Funds are tight right now, but I think I can swing the extra $100 to double the RAM -IF- it will make a difference.
Any thoughts as to wether the extra $100 will be worth it, or am I wasting my money? Thanks!

Hatter,
Thank you so much for your advice! If I may bother you to receive one final suggestion....
Based on the best prices I have found from all of the well known Mac Pro memory dealers, I have narrowed it down to 3 configurations that are balanced. Even though I'm still not 100% confident that 8GB of RAM will give me any noticable imporvement over 6GB, the price is only $42 more to get 8GB. Am I correct in saying that the early Mac Pro would do better to have one matched quad set of RAM over the new Mac Pro's increased performance of having all eight slots filled? Here are the 3 configurations and prices.
4 x 1GB + 4 x 512MB = 6GB Quad+Quad $220 (using my stock 2x512MB sticks)
4 x 2GB = 8GB Quad $262 (pulling my stock 2x512MB sticks)
8 x 1GB = 8GB Octal $278 (pulling my stock 2x512MB sticks)
Which do you think would be the best route?
I already purchased a WD Caviar for my dedicated audio drive. I installed a Seagate 7200.9 in my PowerMac G4 for it's audio drive, but after reading various reveiws, concluded the WD Caviar is a better performer. I LOVE my WD My Book Studio external. I hadn't considered replacing the boot drive, but after reading articles suggesting that it improves overall system performance, and now that you've recommended it as well, I will probably buy a second Caviar for the boot/system drive.
This computer is a DEDICATED audio computer, for ProTools & Logic only....other than a bit of fiddling in Final Cut Express. It's not even connected to the internet and all unnecessary apps are not installed or uninstalled. I also never migrate apps, but always do a fresh install of everything from the ground up.
Thanks again for your advice! It's been a big help!
