Sun 74110 Unified Storage Share LUN settings for best database performance

We have been having performance issues with our Sun storage boxes using iscsi. I want to know what the best LUN settings should be for Database and Log LUNs for Write Syncronous Bias and Write Caching should be for each LUN.
Thanks,
J

I do not have any 7000 series storage but have you seen this Blueprint?

What does Apple mean by "For best battery performance, leave your device connected to a power source until the restore is complete."

I just recently returned an IPad air and exchanged it for another. I first set up this new one as a new IPad but then deleted all content and settings right away (since I wasn't getting the progress I had made in apps and games) in order to restore it from my previous IPad Air. I then checked after on how to backup via icloud and saw this line under the subtitle of how to restore from a backup, "For best battery performance, leave your device connected to a power source until the restore is complete." What does Apple mean by "for best battery performance"? Im just a bit worried of issues.
p.s. And yes I did have it connected to the power. And the ios is the default ios for new IPad Airs.

Welcome to the Apple Community.
It only means you should restore whilst it is connected to a power supply, so that your battery doesn't go flat during the process.

Best Scheme For Capturing For Best MPE Performance?

So let's say I'm still capturing from MiniDV tape @ 720p24. What's the best scheme for capturing for best MPE performance? I have a new HP Z800 with (so far) one i7 4-core with 12 gigs of ram and an Nvidia GeForce GTX285.
[moved from the FAQ forum]

You have to forgive me. I've been using Matrox RT.X2's for so long, I didn't realize there were no codec options when capturing from HDV tape, like there is with the RT.X2. So now I wonder how the MPE handles the playback of HDV captured footage.
I'm anxious to see what my new HP Z800 with one i7 quad core, 12 gigs of ram and Nvidia GeForce GTX 285 can do with PPro CS5. I got it two months ago and haven't even turned it on, waiting for CS5.

VMware Fusion Ideal Settings for Best performance

Can someone please help with the ideal settings for VMware Fusion on mac for best performance.
My Machine Details
MacBook Pro (13-inch Late 2011), Mac OS X (10.7.3)
Processor : 2.8 GHz Intel Core
Memory : 16 GB 1333 MHz DDR3
Storage : 750 GB SATA Disk
Graphics : Intel HD Graphics 3000 512 MB
Am using VMware Fusion Version 4.1.2
At Present the resources I have allocated for VMFusion are
Processor : 1 Core
Memory : 4 GB
Thanks
Brij

VMware Fusion doesn't slow down the Mac just because having it installed. You have 16 GB of memory in the computer and you assigned 4 GB for the virtual machine you have, so you shouldn't have any memory problem. Also, your Mac has got a great processor that run virtual machines without any problem.
If you feel your Mac slow while running the virtual machine, just reduce the amount of memory assigned to the virtual machine, depending on the operating system you have in the virtual machine. For example, I recommend 2 GB or more for Windows 7, and you can run Linux virtualized assigning only 512 MB of memory

Settings for best quality DVD

Hi,
I'm hoping someone can help me to get the best quality DVD for home movies.
I have been editing and putting the movies to DVD for a number of years and the quality has been excellent. but over the last year something has changed and the quality of the final DVD is quite poor (pixalated)
I have tested different settings in both imovie HD and idvd but it hasn't made any difference so far.
I am using the following:
Sony HDR-HC9 handycam (Recording in HDV1080i)
imovie HD 6.0.3
iDVD 7.1
Thanks for any insight you can give me!

Hi
As written - dust on lens - first thought
If You made a lot of DVDs in a row (>3 at a time) then there is a risk to burn out/harm the laser.
my list on DVD Quality - read or keep. It's long !
*DVD quality*
1. iDVD 08 & 09 has three levels of qualities.
iDVD 6 has the two last ones
• Professional Quality *(movies + menus up to 120 min.)* - BEST
• Best Performances *(movies + menus less than 60 min.)* - High quality on final DVD
• High Quality (in iDVD08 or 09) / Best Quality (in iDVD6) *(movies + menus up to 120 min.)* - slightly lower quality than above
2.Video from
• FCE/P - Export out as full quality QuickTime.mov (not selfcontaining, no conversion)
• iMovie x-6 - Don't use ”Share/Export to iDVD” = destructive even to movie project and especially so
when the movie includes photos. Instead just drop or import the iMovie movie project icon (with a Star on it) into iDVD theme window.
• iMovie’08 not meant to go to iDVD. Go via Media Browser or rather use iMovie HD 6 from start.
3. I use Roxio Toast™ to make an as slow burn as possibly eg x1 (in iDVD’08 or 09 this can also be set)
This can also be done with Apple’s Disk Utilities application.
4. There has to be about or more than 25Gb free space on internal (start-up) hard disk. iDVD can't
use an external one as scratch disk (if it is not start-up disc).
5. I use Verbatim ( also recommended by many - Taiyo Yuden DVDs - I can’t get hold of it to test )
6. I use DVD-R (no +R or +/-RW)
7. Keep NTSC to NTSC - or - PAL to PAL when going from iMovie to iDVD
8. Don’t burn more than three DVD at a time - but let the laser cool off for a while befor next batch.
iDVD quality also depends on.
• DVD is a standard in it self. It is Standard Definition Quality = Same as on old CRT-TV sets and can not
deliver anything better that this.
HD-DVD was a shortlived standard and it was only a few Toshiba DVD-players that could playback.
These DVDs could be made in DVD-Studio Pro. But they don’t playback on any other standard DVD-layer.
*Blu-Ray / BD* can be coded onto DVDs but limited in time to - about 20-30 minutes and then need
_ Roxio Toast™ 10 Pro incl BD-component
_ BD disks and burner if full length movies are to be stored
_ BD-Player or PlayStation3 - to be able to plyback
The BD-encoded DVDs can be playbacked IF Mac also have Roxio DVD-player tool. Not on any standard Mac or DVD-player
Full BD-disks needs a BD-player (in Mac) as they need blue-laser to be read. No red-laser can do this.
• HOW much free space is there on Your internal (start-up) hard disk. Go for approx 25Gb.
less than 5Gb and Your result will most probably not play.
• How it was recorded - Tripod vs Handheld Camera. A stable picture will give a much higher quality
• Audio is most often more critical than picture. Bad audio and with dropouts usually results in a non-viewed movie.
• Use of Video-editor. iMovie’08 or 09 or 11 are not the tools for DVD-production. They discard every second line resulting in a close to VHS-tape quality.
iMovie 1 to HD6 and FinalCut any version delivers same quality as Camera recorde in = 100% to iDVD
• What kind of movie project You drop into it. MPEG4 seems to be a bad choice.
other strange formats are .avi, .wmv, .flash etc. Convert to streamingDV first
Also audio formats matters. I use only .aiff or from miniDV tape Camera 16-bit
strange formats often problematic are .avi, .wmv, audio from iTunes, .mp3 etc
Convert to .aiff first and use this in movie project
• What kind of standard - NTSC movie and NTSC DVD or PAL to PAL - no mix.
(If You need to change to do a NTSC DVD from PAL material let JESDeinterlacer3.2.2 do the conversion)
(Dropping a PAL movie into a NTSC iDVD project
(US) NTSC DVDs most often are playable in EU
(EU) PAL DVDs most often needs to be converted to play in US
UNLESS. They are plabacked by a Mac - then You need not to care
• What kind of DVDs You are using. I use Verbatim DVD-R (this brand AND no +R or +/-RW)
• How You encode and burn it. Two settings prior iDVD’08 or 09
Pro Quality (only in iDVD 08 & 09)
Best / High Quality (not always - most often not)
Best / High Performances (most often my choise before Pro Quality)
1. go to iDVD pref. menu and select tab far right and set burn speed to x1 (less errors = plays better) - only in iDVD 08 & 09
(x4 by some and may be even better)
2. Project info. Select Professional Encoding - only in iDVD 08 & 09.
Region codes.
iDVD - only burn Region = 0 - meaning - DVDs are playable everywhere
DVD Studio pro can set Region codes.
1 = US
2 = EU

What it turned out to be was the "quality" settings in iDVD. The total clip time was NOT over 2 hours or 4.7GB, yet iDVD created massive visual artifacts on the "professional quality" setting.
I switched the settings to "high quality" which solved the problem. According iDVD help, "high quality" determines the best bit rate for the clips you have.
I have NEVER seen iDVD do this before, especially when I was under the 2 hour and 4.7GB limits.
For anyone else, there seem to be 2 places in iDVD to set quality settings, the first is under "preferences" and the second under "project info." They do NOT seem to be linked (i.e. if you change one, the other is NOT changed). take care, Mario
TO GET IT TO WORK SLIGHTLY FASTER
• Minimum of 25Gb free space on Start-Up hard disk
• No other programs running in BackGround eg EnergySaver
• Don’t let HD spinn down or be turned off (in EnergySave)
• Move hard disks that are not to be used to Trash - To be disconnected/turned off
• Goto Spotlight and set the rest of them under Integrity (not to be scanned)
• Set screensaver to a folder without any photo - then make an active corner (up right for me) and set
pointer to this - turns on screen saver - to show that it has nothing to show

NLS settings for a database link between DBs with different character sets

I am using a database link to move data from one database to another and I am seeing some strange data problems. The databases have different character sets and different NLS settings. I wonder if this could be causing my problem.
Here are the NLS parameters for the database where the database link exists. (the SOURCE database)

Do I need to modify the NLS settings in the SOURCE database before executing a script to insert data into the TARGET database?
Thanks, Jack

The difference in settings is not a problem by itself, especially that only the NLS_CHARACTERSET matters. Of course, this difference may lead to certain issues if not taken into consideration.
Please, describe symptoms of your problems.

Export settings for best quality for pages with letters etc.

Hi, I am trying to make video of a musical piece, featuring the score of the piece with pages turning following the progression of the music. I made the video in Adobe After Effects CS5 and exported it so it would be lossless. The video itself is a .mov file and looks great when I view it in Quicktime, but when I import it into FCE the quality goes down a bit. I don't know if FCE is handling the clips correctly or if it's just for making it quicker to view. Any suggestions on export settings from FCE for best quality of a video of this nature, so that the notes are clearly readable.
Thanks in advance
Ps. It has to be in a format suitable for Youtube.

Under "Sequence" and in "Settings" and in the tab "Render Control" I have: Frame Rate: 100% Resolution: 100%.
If that is what you were referring to... but under the tab which is called RT and is located left of the timeline and left of the timecode. There I have checked : Safe RT, (Playback Video Quality) Dynamic, (Playback Frame Rate) High.
There might be a way to import the clip in better quality (so it doesn't downgrade the quality).
Was mostly trying to find out with the export but it might have something to do with this.
Thanks

What kind of storage we should use for oracle database?

Hi
thank you for reading my post
Can some one please explain what kind of hardware storage is common for oracle database, and kindly please provide some explanations about the reason that we can use such storage?

Perhaps you're thinking about RAID, an acronym for Redundant Array of Inexpensive Disks? That's not specific to Oracle by any means, it's a very common way of setting up multiple disks in a server so that the failure of one or two disks doesn't cause the system to lose any data. If you're dealing with a server of any size or any sort of SAN or NAS device, it is going to use RAID, the question is which form of RAID (there are different sorts of configurations with different levels of cost, performance, and durability).

AVCHD - Blu-ray: what settings for best quality?

Hi Folks,
I've got a BD-burner and I want to export my edited HD avchd footage to BD with minimal quality loss.
Can you please advice me on the right settings?
* should I go for the 'Match Sequence Settings' option in the export menu?
* or probably select 'MPEG 2 Blu-ray' option for best quality?
* what is better in terms of quality of the outcome: 'MPEG 2 Blu-ray' vs. 'H.264 Blu-ray'?
Finally, I have a question related to Adobe Encore: the same footage exported through Adobe Media Encoder in 'MPEG2 Blu-ray' (takes 13 GB), Adobe Encore reports will take only 8GB?!? I'm puzzled here. How come the same footage got exported into files with different length? Is there a way to set the Encore to export in the maximum possible quality? Where can I locate this menu setting?
Thank you very much!

Forgot to mention, I'm using CS5 and I shoot in avchd, 30fps,
1980i

Workflow and settings for best quality .png export

I need to export a vector image to a .png for use on Retina display devices. What is the workflow and settings for exporting that results in the best possible quality .png image?

The workflow I used to produce the previously posted image on a WIndows 7 PC:
File>Export>Set "Save As" type to PNG
Upon pressing the "Save" button a PNG Options window will appear.
Resolution: Screen (72 ppi)
Anti-Aliasing: Type Optimized (Hinting)
I contacted Adobe support and they told me that the only way to export .png is via "Export" or "Save For Web".
"Save For Web" is designed to compress and I wanted to avoid that to ensure retina display quality.
I chose 72 ppi instead of a higher setting (support suggested I use 300 ppi) because Apple retina displays do not recognize ppi above 72.
The Anti-Aliasing setting was my default and I read somewhere that this was the best for getting crisp edges on retina displays (Sorry, I cant recall the source)
My concerns are that the export and anti-aliasing make larger files and I'm not convinced they are noticably better quality than "Save For Web".
Also, it's worth noting that the support was clearly reading from a reference guide. It was not a "real" expert that could explain the best workflow.

Book - best settings for best photo quality

What are the best settings for my photos in order to get the best quality book?
Thanks
Zasa

zasa:
Use the largest file, pixel wise, that you can. The books are printed at 300 dpi so the largest size the better to insure you'll get as close to that dpi for the largest page picture possible.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Settings for best quality freeze frame export?

Hi. I've done some reading in the search for this topic here, but I'm finding a lot of how-to's for exporting freeze frame, but not proper settings.
Using DV NTSC 29.97fps, I know it's far from ideal to get great quality still frames, but, I have a client who was disappointed with her photographer at her wedding and really liked my work and she is willing to pay me to go through and pull off stills from her wedding video.
I do this for virtually every wedding but I just use basic settings because the still frames are used for not more than dvd menu or perhaps a small image on the back of the jewel case.
But if she wants to print these then I'm wondering if someone here can offer suggestions on the proper settings to make them not only the best quality, but the proper dimensions.
Thank you,
Eric
(soon-to-be-proud-new-owner-of-a-macpro-!)

From DV NTSC, your exported still frame will be just 720x480 pixels. Use any image editor to resize that to 720x534 (if it is NOT widescreen) or 864x480 (if it IS widescreen).
( Looks horrible doesn't it? You can't get any better quality than that, just because you - or she - wants to.)

Best settings for best movie export?

I would like to export my Keynote presentations as QT movies, full size, best quality. But when I do the transitions are very choppy.
Any suggestions on exporting so that the transitions are smooth and it looks more professional?

Hello Mark,
I've done quite a bit of work with Keynote, and use it in conjunction with iMovie and iDVD. I assume you would want widescreen? HD720p is the format that gives the best result. Set your document size to reflect this, at 1280x720 pixels. Export to QuickTime at 'Full Quality, Large'. Make sure you have set you export for PAL or NTSC depending on need, and make sure the info in the settings panel reflect your choice. If they don't, choose 'Custom Settings'. Make sure you use 'Apple Intermediate Codec' and change the frame rate to suit, 25 for PAL and 29.7 for NTSC. I've found this gives me exceptional quality, but they will look and play better in iMovie than the QuickTime player for some reason.
I hope that's of some help.

Best image EXPORT settings for best quality

What should i have my export settings at when exporting to a jump drive to give to clients for web and printing use???
When i see my images uploaded on Facebook for example, the qulity looks poor which worries me that when printing the quality will be poor as well. Am i missing something in the setting for exporting? What is the proper way to export for the best quality image? HELP!
My settings now under Aperture>Presets>Image Export:
JPG Original size
300 dpi

No, not for one size fits all.
I do appreciate this may be a frustrating answer, but non-the-less, that's how it is.
t_hall10 wrote:
Should I be gving 2 folders of pictures, one for web use and one for printing use? If I were to do that, what should the exporting setting be set for both folders?
Maybe, it's your choice.
Let's go through the settings.
The only real quality setting is for JPG compression. 12 is virtually no (lossless) compression but gives huge file sizes which may breach a websites limits.
A 16MP images on quality 12 will be about 22MB. 11 brings it down to 8MB and 10 down to 7MB. You'd be very hard pressed to see the difference between a 12 and a 10. But if you want to feel you are giving the best quality without the extreme file size, go for 11.
The the vast majority of web sites, like facebook, will either resize uploaded images and/or re-compress them. They may also crop them to a different aspect ratio to fit their browser software.
Many report the best size for upload to facebook, for small images is 960 pixels on the long side. For large images it's 2048. For different websites it may be different. It is discussed on many photography sites and blogs. You will find some promoting the 960 / 2048, and others with their own preferences. Here's a good one which also shows you many ways FB will mess with the images:
http://havecamerawilltravel.com/photographer/images-photos-facebook-sizes-dimens ions-types
The safest colour space is sRGB (Mac profile: sRGB IEC61966-2.1) as it will more often be right than wrong. You should preview your images on screen with this profile to get a feel for how it will look and avoid unexpected colour shifts in your files. Ideally your screen should be calibrated so you know what you are giving them is accurate.
To understand the printing issue, try this exercise:
If you have a printer installed on your Mac, it probably also installed some printer profiles. In Aperture, look at one of your nicer vibrant images. From the view menu turn on 'Onscreen Proofing' and then from the 'Proofing Profile' sub menu, select one of your printer profiles and look at how the onscreen image changes. Repeat with each of the printing profiles and see how the image changes each time.
This is only a fraction of the colour shifts that will be occuring after you give your file to someone and they print it on their own uncalibrated system with their uncalibrated printer.
Many photographers don't offer full size images to their clients. They will usually give them smaller versions for their own use, which may include small size printing.
They will either do the main printing themself on their own calibrated printer, or work with a print shop, and may have installed calibrated profiles on their system for the shops printing equipment so they can use onscreen proofing to gauge what the pictures will look like when printed on that equipment.
But if you are just giving a file to someone, you lose all control of how they will print it. Even experienced photographers and computer users can struggle to make the prints match close to what they look like on screen.
Most often photos will appear too dark, or the colours look wrong, or it lacks sharpness. There are some settings on the export presets for gamma and blackpoint compensation. Gamma will brighten the image for when it's printing too dark, and blackpoint will try to stop the shadows turning black (within the chosen colour space). But as you don't know in advance whether the images are going to print too dark, or the shadows are turning black, you can't really set these for a one-size fits all scenario.
So there are not many settings to help you here.
You are actually moving into the realm of defining your product. You could, for example, ask the client which site they intend to publish the photos on, research that site and produce files optimized specifically for that site.
You also need to decide what size (resolution) files to give them for printing and whether you are happy giving away your full size images.
These choices will lead you to a number of a different files sizes as 'your product', all should be in sRGB colour space, and all with quality 10 or 11. For any client's who know how to make use of a wider clour space like Adobe RGB for printing, they will probably ask you up front to supply the print versions as such.
Next, for each size and usage, you now need to sharpen these images.
This is because sharpeing is best applied to images that have been resized to their intended output size and should be sharpened in accordance with how they will be viewed. Images displayed on computer screen generally need less sharpening than those that will be printed. Depening on the printer, the images may need some oversharpening in the file, in order to appear crisp and sharp in the print. As you won't be controlling the printing process you should probably avoid oversharpening. The bottom line is, if people are taking on the task of their own printing, they'll need to figure out what they are doing to get good results, or use a commercial printer.

Thanks.

It does not make any difference for the 4G iPod since iTunes optimizes the photos for the iPod, iPhone and iPad. see:
