Need quorum advice for production configuration...

I am trying to define a policy for how we will use the new Quorum feature when our project enters production. I have read the information in the manual but would like to confirm that I understand how it works as well as get some more advice!
We are running a cluster using a "cache beside" pattern where the cache is pre-loaded with the full dataset at start-up and after that kept in sync with the database using XA (2PC). No eviction or lazy loading is used. If we loose any data due to to few remaining nodes to hold the full data set we needs to stop service while we re-load the cluster from database (may take in excess of 20 minutes so this is quite bad!). We will run multiple Coherence nodes (probably like 4) on each storage server (they will be configured with the same machine-id) and the number of storage servers and application servers will most likely be 3 and 2 at our first very limited deployment. When at full capacity this may grow to perhaps 8 and 5 or even more. Due to the low number of storage servers (in particular in the initial deployment) we intend to keep spare memory capacity for only one server failure. We will use two "role names" lets call them "storage" (for the storage enabled nodes) and "app-server" (for the non-storage enabled nodes).
In the initial limited-deployment scenario (3 storage nodes) we will (if I understand Coherence properly) actually be able to handle a second server failure (if it occurs after re-balancing from the first is completed) but the cluster is then running in as vulnerable state since Coherence will not maintain backups when all remaining nodes have the same machine-id (this is good since we with a single server would not have room for both primaries and backups).
Q1. I would ideally like to be able to get the same effect in the larger cluster - i.e with say 8 storage servers (32 storage nodes) I would still like to drop all backups if a second server fail (after the first re-balancing has terminated) since this would allow the cluster to continue operating (in a vulnerable state) rather than break due to an out-of-memory state (if we loose more than one storage server there will not be room for both primaries and backups). Is it hoping for to much that this can be achieved using the Quorum settings?
Q2. Cluster Quorum - Ideally I would not like to loose more than one node (I could actually tolerate to loose all nodes on a single server but there is no way to specify that) due to a "temporary" network outage (since loosing more is very likely to result in lost data and a service outage while re-loading the cluster) but how far towards that goal does this setting take me? Or more generally what is the pros and cons of specifying a high value here?
Q3. Distribution/Restore Quorum - What scenarios are these settings intended for? Do they apply to my case outlined above in Q1 (to avoid new backups to be created when fewer than a specific servers are available) or?
Q4. Read/Write Quorum - Seems straight forward in our case. If the clusters drops below the number of nodes required to hold the full dataset both reads and writes should be blocked since writes are likely to fail (will be caught by our XA transactions but may as well be blocked out already by Quorum) and reads/queries may be incomplete. These values (at least write) should of course under all circumstances be set to a higher value than the number of nodes / 2 to avoid "split brain" ....
Any comments, corrections to my understanding of Coherence error recovery (or Quorum functionality) is warmly appreciated!

I'm currently using an older version of Final Cut Pro-- version 5.0.4.
That will not run properly on your iMac. Your iMac is an intel processor. You need at least 5.1 to run on an intel processor. There was an update available years ago but not currently. You need to upgrade your FCS to work with AVCHD. The cost is only $300 for the upgrade. You need it to use your camera and your iMac.

Need a Advice for move from peoplesoft to SAP BI

Hi Experts,
I am working as a peoplesoft Technical consultant in a MNC past 2 yrs .
I want to change my domain to SAP BI. I need a suggestion.
SAP BI Training already completed. But in my it's not possible for change so please advice how i will highlight in Resume.
So that i will get calls for intv.
Please guide my Guy's.

Hi Yxu,
I see what you mean now. It sounds like you'll need to pull in the tables from various studio databases and also edit some of the native studio application tables to associate the new tables. Unfortunately I've never tried this and don't have any instructions I can share with you. In terms of the portlets, i'm not sure how easy it would be to migrate them. You could upgrade the various WCI instances to 10g then use the migration utility to move the studio portlets to your main wci 10g instance. Or like you said, create new portlets. Keep in mind direct manipulation of your databases can render your product unsupportible by technical support. The more supportable alternative may be to just build all the studio databases and portlets from scratch in the new instance.

Ryan

Need conceptual advice for 16:9/4:3 menus

Hi,
First off I should say that I am undertaking my most ambitious DVD project to date and I am in well over my head. I want to order a book(s) and would appreciate any advice regarding which book(s) might best deal with the type of issues I am about to explain. BTW I am still using DVD Studio Pro 2.
So here it is:
I have a 16:9 feature and 16:9 menus. My issue is their appearance in 4:3.
When displayed on a 4:3 monitor, I want the 16:9 menus cropped to full frame (pan and scan) and the feature to play 4:3 letterboxed. Since it seems like there might be some counter-intuitive aspects to this process, some general conceptual guidance on the authoring and menu design would be great. I am hoping that the authoring can be done with this sort of “mix and match” way and not pan and scan OR forced letter box for both menus AND video. Here is what I am sussing out so far:
1) I should set “force to pan and scan” in the disc inspector. I am assuming that this setting is ONLY for the menus (as they appear on 4:3). And if I am forcing a pan and scan crop of the menus I can just use the same overlay file for both 16:9 and 4:3. I just need to make sure my 16:9 menus are visible and can function once cropped to 4:3.
2) Regarding the video tracks: It looks like I might have to put the feature on two different tracks, one designated to play 4:3 and the other to play 16:9 letterbox in the track inspector? (why it is not labeled 4:3 letterbox and 16:9 is still a mystery to me). And it is at this point (that soon!) that things start to get cloudy. Because suddenly it seems that if I do that, I need two separate menus (rather than the 16:9 doubling as the 4:3), a16:9 one to point to the 16:9 video track and the 4:3 to point to the 4:3 letterboxed video track. Ideally a 16:9 the menu would point to track 1 and it would play 16:9, and when watching a 4:3 the 16:9 menu would automatically crop to 4:3 letterbox and point to track 1 which would then play 4:3 letterbox. Is that just some crazy dream or can it really work like that? So what is the story here?
3) If I am forced to use two separate menus, a whole other series of questions are raised. But I won’t go there just yet.
So you can easily see that I really have little idea of what I am doing in this regard and am in need of some expert advice. Thanks in advance.
-Thomas

Hi Thomas
If you are using DVD Stuido Pro 2 Force to Pan and Scan doesn't work. Not sure if it works in later version of DVD-SP (Don't think it did in V3 and not sure about V4). We do quite a few widescreen 16:9 movies and I'd do it like this: If you feature is 16:9 set that to 16:9 Letterbox. On the Disc Properties (i.e. click on the disc at the uppermost part of the disc layout set the Menus to Force to letterbox. Create your menus in 16:9 and set them to 16:9 Letterbox.
That way when the disc is played on a widescreen set the menus and track will display as widescreen (as they should) and when played on a 4:3 set they display with Letterbox - apart from the fact that the Force Pan and Scan doesn'y work properly (the highlights on your menus won't line up properly), I personally think this is preferable... especially when it comes to the movie itself. When a movie is Pan and Scanned on broadcast tv (which happens less and less these days) the film's action is "tracked" so that the most important info is displayed on screen and Pan and Scan Vectors are created. If you set your track so that it displays as 4:3 on a 4:3 set then basically you will only see the centre of the screen/action. Why would you want that? I thiunk most people with 4:3 sets are used to seeing widescreen letterboxed movies these days.
Hope that helps
Steve

In need of advice for backing up HD Video

So we returned from a vacation,
where I shot all the video in HD 1080p.
We got back, and I used Final Cut Express to convert the AVCHD files from .mkv to .mov files.
All together, the total files come to a whopping 78.93 GB. Wow.
I need to back these up to DVD's or something
(My wife says she doesnt want them on an external hard drive, her last one died)
is there a way I could compress these?
or should I use quicktime/visualhub to bring down the quality a little?
any advice would be greatly appreciated
thanks

Solutions:
1) ignore the wife and backup to a good hard drive such as a LaCie quadra. usb or firewire.
2) Buy Time Capsule and backup to it.
3) what would i do? Use MPEGStreamClip to make mp4 files , to control the file size. The picture will still look very good but it does not do 5.1 channel sound. Handbrake does but since the file is HD probably will crash while encoding so will VisualHub. Another consideration, MPEGStreamClip on a 2 gig HD movie will take 15 hrs on a Mac pro let alone an iMac.
Currently not too many programs will do HD encoding.
4) backup to optical disc, I'd never do that ; too many compatibilty issues with different drives perceived for future usage.
5) back to the wife, user should alway have three backup stategies; ie main drive then backup # 1 then backup #2. I've backup to external and internal hard drives for over a decade without problems.

Need licensing advice for a school

I'm not sure how to approch server licensing for a school.
We currently have a 2003 domain licensed "per server" , 500 users
we want to relpace the DC with a 2008 server and the academic edition of the OS
My questions are these: are there academic licenses? and what would be the best licensing option (per server or per user) if we will need 368 user accounts and 1 server?

Hello,
I would recommend contacting a Microsoft licensing expert in your country for more information.

Need professional advise for product photography lens for Canon 7D

I am a graphic designer with a lot of experience in the studio but I now find myself needing to do my own product shots in my home studio space of 12' x 12.' I am looking hard at the Canon 7D moving up from 40D and I need to know the best lens or lenses to shoot items such as rifles, glassware, china, and small housewares, etc. I will also need to purchase either soft boxes or umbrellas and am looking for advise on this issue as well. Photos will be used for e-commerce and possibly for catalogs. All comments appreciated!

Hi,
This is not an easy question that can be answered with a short reply, but here there are some items you might find helpful:
LENSES:
Considering the 1.6x crop factor of your EOS 7D, I think a Canon 50mm 1.4 USM should be fine for many of your shots, assuming you have enough space in your room and the item is not too large, otherwise you should go wider to EF 35mm f/2.0 IS USM or the more expensive EF 35mm f/1.4L USM
Of course, if you want a wider range of focal lengths to work with and lot more versatility, then you might want a Caon EF 24-70 2.8L II USM (our favorite) which has excellent sharpness and IQ, but it's more expensive. It's not so "fast" compared to the above, but in studio conditions you'll probably won't use faster apertures than f/2.8 or f/4
The advantage of these lenses compared to EF-S ones, is that if you switch to a full frame camera in future, you will be able to use them as well without any issues. Good investments in our opinion.
LIGHT STANDS & ACCESSORIES:
These are some cheap but very nice built quality stands & accessories that won't hurt your budget:
- Impact - Air-Cushioned Heavy Duty Light Stand - Black,9.5' (2.9m)
- Impact - Telescopic Collapsible Reflector Holder
- Impact - Umbrella Bracket with Adjustable Shoe
- Impact - Umbrella - White Translucent (43")
- Impact - Convertible Umbrella - White Satin with Removable Black Backing - 45"
Of course there are lot of other options, but these ones have worked pretty good for us, considering their price.
You can also attach softbox, etc.
Hope this helps!

Need webcam advice for older Powerbook

Hello!
I've had my G4 aluminum Powerbook for about 5 or 6 years, and it is a wonderful machine. I recently upgraded to Tiger. I connect to the Internet wirelessly through Airport and a router connected to my husband's desktop G4.
I am having a bit of trouble figuring out how to accomplish one thing: I'd like to set up a webcam at home on my machine to watch my dogs while I'm at work (on a PC). I understand the iSight is no longer available, and Apple tells me it has a lovely Logitech Quickcam Ultra Vision that will allow me to chat with video. But I don't think chat will work work: I want a streaming video to come from my webcam that I can access through the Internet at work.
First, is this possible, given my set-up. And second, would the Logitech work and with what software?
Many thanks for your wise advice.

Here are two fantastic resources for you.
1) Macam, which has a list of ALL compatible webcams with Mac OS X, via USB
[http://webcam-osx.sourceforge.net/cameras/index.php]
2) iChatUSB, which is a software/plug-in that also lets you use certain webcams

There's also this one:

The best one I've tried out so far, but returned because I didn't really need it after all (it was for a short-term project at work, and then after the project was shelved, I returned the webcam to the, er, shelves. Ha ha) is the Logitech QuickCam for Notebooks Pro.
It has built-in support and you don't need third party extensions. The clarity is great! Crystal clear images, both video and stills. It has a Carl Zeiss lens, if I remember correctly. And it works right out of the box.
Just be careful to get the right model number. There is a note of this on those first two sites above. A note about an earlier version (part no.) but same box could mean the difference between it working and not working. Something about UVC compliance.

Need Uninstall Advice for Final Cut Pro 5.0

Ok, so I recently upgraded to Final Cut Pro 5.0 from 4.5 HD. My computer is a G4 dual 450 mhz and is relatively stock (Rage 128 AGP card) with a few upgrades to the ram and hard drives. Unfortunately I failed to read the "Before you install Final Cut Pro 5.0" file and didn't realize I need a Quarts Extreme AGP card to run FCP 5.0. I can't afford to buy one right now, so I want to downgrade back to 4.5 HD. Is there an easy way to do this? I tried deleting all the FCP files and reinstalling 4.5 but it tells me to try again due to an error. Is there a file I'm forgetting to delete, or an easy way to uninstall 5.0, or a way to use 5.0 with the Rage 128 AGP card? Thanks
-Julian

A search of the FCP forum for AGP yields many results for this ... among them is: http://discussions.apple.com/thread.jspa?messageID=2339613&#2339613
Do the hack and you should be running fine with FCP 5

Hi Khan
The first servers to be updated in a site are the Mailbox servers even if they are member of DAG.Ensure the DAG node you are updating is in maintainence mode. The Client Access servers are updated second. If you have multi-role servers installed then
both roles are updated at the same time anyway, and you should simply start with the internet-facing servers.
First, you will need to remove any UM language packs that you have installed in previous version. From an elevated cmd prompt navigate to the folder where you have extracted the Exchange 2013 SP1 files and run setup with the /RemoveUMLanguagePack switch. For
example, to remove the “en-us” language pack.

I need some advice for my upcoming June purchase.

Ok, In June, im going to be purchasing my first Mac. Now I have used Macs before, tons of times. I work on a powerbook G4 everyday. Im familiar with the whole Macintosh workings. Basically, im just saying that Im not clueless with a Mac.
So anyway, im buying a MacBookPro in June. My question is about getting it to run the best it can. I already know that I dont have to worry about viruses/spam/spyware or anything like that. but whats the best thing to do from the beginning to get the most out of your MBP?
I believe I read something about doing a fresh install or something first. and disabling printer drives...how do I do that and how does it affect the MBP? My main uses on it will be Video Editing, Internet, Sound Recording, and iTunes. Im just asking if anyone can give me some ideas that work to better the computer and get rid of as much things that I wont ever use as I can. I appreciate anyone who attempts to help me out on this.
After reading up on the internet for a couple hours, I finally got my iPod runnin' like a street racer. I customized the settings perfect so that I only use it for what I need it for. But my MBP will have more to it, and cost a bunch more!
Once again, in advance, thanks for anyone who can help.

Woh...Slow down. You are trying to shave programs off before you even try them.
You will start off with a fresh install. The people who advise that are telling people who have tweaked their system to do a fresh install.
Take your time. Keep reading these posts. Also, try reading www.macworld.com, www.macfixit.com and of course Apple's own site for switchers.

I need good advices for a Nokia N95 please...

I'm going to buy a Nokia N95 from a GSM Store near me and I wish to check first if the phone it's original. I know that there are some things I must check ( The star *, the seventh and eighth digit from IMEI, the size of the camera, if there is written Nseries on the back of the phone,under the Nokia logo) but anything else I don't know....so is there anything that I can check which is only, and only for Nokia original phones....something that the replicas don't have? I'm asking this because I deeply want not to get hoaxed.
Thank you so much for your help,
David

look carefully under the battery where it was make if its not Hungary or Finland it might be fake...
look at the menu and touch the landscape menu and there you can see if it works good or its a fake..I had an N95 and it was made in finland at everything was ok it was original but before i bought it I payed attention at battery, production country, camera settings and qualitty, the slide and the quality of screen..If its fake you can observe pixels on the screen faster then at the original phone...
I hope this would help you

Need some advice for design/build vs. licensing a modifiable solution

Hello MS Forum,
I'm looking to design a webportal for my business that tracks responses to advertising on radio, TV, newspaper and the web. Basically, advertisements draw inquiries to either a call center or website/survey, where they are vetted and referred to service
providers in their respective geographies.
The call center will manually enter collected data, where the website survey will automatically map the answers to their respective fields in the webportal and assign a random ID.
External users will log in to get their vetted leads/referrals, but can also manually enter self generated leads. I want to be able to track the external user activity as well, i.e. change audit trails, time stamps on free text comments that incl.
users name, edit checks that don't allow fields to be left blank, etc.
Is there a modifiable solution out there with all the advanced informatics, or will I need to build this thing from the ground up? Any help would be VERY much appreciated.
Many thanks,
Brruss1

Need system advice for FCS2

I have a bit of a problem. My 3 year old G5 has a dead AGP X800. No warranty left. I can't find a replacement for it. Ebay sellers are getting around $400.00 for used versions. Used video card sounds like trouble. I am thinking of getting a new intel version Mac Pro but not sure if the 8 core macs are a must for Studio 2 apps. The 2.8 dual core goes for $500.00 less then the 8 core and the 3.0 $720.00 more, 3.2 $1440.00 more.I am working with HDV and DVCProHD most of the time. I also like Aperture. My G5 worked pretty well with the X800 but not with the stock card I had to put back in. I am trying to squeeze the most out of my money. I will need to replace my Kona LH card as well. Lots of money all the way around. I do think the resell on the LH card might be pretty good.
Any thoughs?

Oh man. That *****. I saw on Matrox website that they don't have very many tested and approved cards. Like only five. And the X800 and the Radeon 9600 are my only options with AGP. This just seems odd to me.
http://www.matrox.com/video/support/mxo/rec/display.cfm
As for my problem. I called ATI and from what the tech guy said they will fix my x800 for $80.00. I asked him if they will fix it no matter what's wrong with it and he said yes. I am going to try to salvage the card. Unfortunately I cant edit with the 9600 XT I had to put back in. I keep getting dropped frames with a ProRess timeline. Even DV was dropping frames. Im screwed for a while.

I need some advices for FLASH code optimisation...

Hi All,
Lat me explain what im doing right now for a better picture -
My project was previously done in Director >> Im
reengineering it in flash. Im using a lot of scenes for different
pages. Every pages have buttons and hell lot of audio and MC's. I
have my own script on every scene, frame1. Is this right? most of
the codes are redundant. I cannot access variables and functions
from a different Scene right? (please correct me if im wrong).
And till today I have a huge pile of code. Is there any
concept of Header files like in MFC. If i make an .as file, can i
embed it inside the .fla and use the variables which are there?
Because I dont need an extra .as file along with the
swf(REQUIREMENTS!!).
Please give me an insight on this kind of optimization, i.e
using a concept of header files, #define and stuff.
Another thing is that - there is a MFC program which loads my
SWF file and plays it. The swf loads an image from the harddisk
using the image loader component. Is there any way i can flush the
image data from the RAM or CACHE after the work is over? Or can
this be handled by MFC?
Can MFC unload the flash after its loaded? We are unable to
find a unload option in MFC side for flash OCX controls.
It would be great if someone could help me with this.
Regards
Roshan Kolar

I already know how to get the path of the class file.
