A non-RAC question for the experts: Clusterware + ASM

Hi
We have a 2-nodes cluster in production.
It's an active/passive cluster with a cold failover using SUN Cluster.
There is only one Oracle 10G single-instance database (DB1), running on node #1, that use ASM to access the SAN (it's raw devices).
We want to add a third nodes to move to a 3-nodes cluster, that would have 2 separates single instance Oracle 10g database
node #1: DB1 with ASM (the existing database, existing raw devices)
node #2: cluster passive node
node #3: DB2 with ASM (new additional database, new raw devices)
All nodes are connected to the same SAN.
We' want to use Clusterware instead of SUN Cluster.
The single-instance databases, the listeners and the ASM instances would be protected by Clusterware using "application VIP" (not oracle-vip).
It's not RAC ! but in the future both database might become RAC (but that's not the need today)...
My concern is about ASM !
Do I have to install an ASM instance on each node (just like in RAC) ?
Or may I just configure clusterware to ensure there is only ASM instance running on a node ?
Is it possible to have the ASM instance of node #1 and the ASM intance of node#2 that access the same SAN & raw devices ?
In the case DB1 & DB2 fail over to node#2, the unique ASM instance must see the raw devices of both databases, is this possible ?
Do I have to destroy the curent ASM configuration of DB1 to build the new one, or can I just add new raw devices and share tem across all nodes ?
Thanks for your answers.

Hi,
Thanks for the answer
I found this very interesting doucument but it does not go into enough details about ASM, which is my concern.
I found in the Oracle 11g documentation a statement which say that clustered ASM instances for single instance database do not need to talk each other as long as they do not handle the same diskgroup (Figure 1.3 ; http://download.oracle.com/docs/cd/B28359_01/server.111/b31107/asmcon.htm#i1021337) . Otherwise, it must be clustered. It would also be a problem for me when DB1 and DB2 are on the same node. I would need two different ASM instance, on the same node, which is not a good situation.
What happen when I start an ASM instance on node #3 to access raw devices already in use by node # 2.
I think I need to start from node #1 and change some ASM configuratoion to make it cluster-aware.
Next, I would add a second clustered ASM instance on node #2, and so on, to make sure that all ASM instances of all nodes can access the same diskgroup, and thefore being able to re-use the existing database on node #1 as well as creating a new one one node #2 (all on the same SAN)

Please read my question carefully, this is, I think, a question for the experts. It's not the usual name change question.
When I setup my new MacBook Pro, something slipped by me and my computer was named First-Lasts-MacBook-Pro (using my real first and last name).
I changed the computer name in Preferences/Sharing to a new name and Preferences/Accounts to just be Mike. I can right click on my account name, choose advanced, and see that everything looks right.
However, If I do a scan of my network with my iPhone using the free version of IP Scanner, it lists my computer as First-Lasts-MacBook-Pro! And it lists the user as First-Last.
So even though another Mac just sees my new computer name, and my home folder is Mike, somewhere in the system the original setup with my full name is still stored. And it's available on a network scan. So my full name might show up at a coffee shop.
Can I fully change the name without doing a complete re-install of Lion and all my apps?

One thought... you said the iPhone displayed your computer's old name? I think that you must have used the iPhone with this computer before you changed the name. So no one else's iPhone should display your full name unless that iPhone had previously connected to your Mac. For example, I did this exact same change, and I use the Keynote Remote app to connect with my MacBook Pro. It would no longer link with my MacBook Pro under the old name, and I found that I had to unlink and then create a new link under the new name. So the answer to your question is, there is nothing you need to do on the Mac, but rather the phone, and no other phone will display your full name.

Are these things possible in PDF forms? Questions for the experts

Hi,
I have a project where I need to create an online application system, where the user has to fill in a form where the results have to be saved into a database.
I wanted to create a html based form, but then someone told me PDF can also do cool things, so I’m researching that road.
I already managed to create a simple form and submitting it to a web service (java servlet in my case) and that works pretty nicely.
I'm new to the whole PDF form creating and I’m wondering if certain things are possible. So I’m trying the experts in this form for a yes/no answer.
Are the following things possible with PDF forms:
1) validation: number & date checks, eg, a number should be higher than 4, or be a valid number/date
2) If I answer A at question 1, I should skip Question 2 and go directly to Question 3. Is it possible to hide Question 2, depending on what I answered at Question 1?
3) Is it possible to attach files to the form, like a photo? And also upload it to the web service.
4) After I submit the form, is it possible to lock the form so that no other changes can be made? In other words, you may only submit once.
5) Possible to activate the print button after the form has been submitted?
6) Can a drop-down lists be dynamic? Instead of hard coding the list, calling a web service to fill the values?
Thanks in advance for any insight,
Kind regards
Ido

Hi Paul,
thanks for the quick answer. No my next challange is how to do things
1) validation: number & date checks, eg, a number should be higher than 4, or be a valid number/date
<answer> Yes
I think this is done through the object properties
2) If I answer A at question 1, I should skip Question 2 and go directly to Question 3. Is it possible to hide Question 2, depending on what I answered at Question 1?
<answer> Yes
This is done with subforms and scripting?
3) Is it possible to attach files to the form, like a photo? And also upload it to the web service.
<answer> PDF does support the ability to have attachments. They would be includeed as part of the PDF so you woudl have to submit the entire PDF and then extract the attachments when you get the file to the server. Note that you will require to Reader Extend the document to allow a Reader user to add the attachment. This is not a requirement if you are using Acrobat.
Have to look into this one.
4) After I submit the form, is it possible to lock the form so that no other changes can be made? In other words, you may only submit once.
<answer> Yes
Also through scripting?
5) Possible to activate the print button after the form has been submitted?
<answer> If you add a print button on the form then the answer is Yes. The application that houses the PDF will jhave print capabilities and that one is much more difficult to hide. You can set it up so that the form cannot be printed then return back the locked version with printing enabled but a round trip to the server is required for that.
Print button will be fine by now, probably also done by scripting
6) Can a drop-down lists be dynamic? Instead of hard coding the list, calling a web service to fill the values?
<answer> Yes but the form will require LiveCycle Reader Extensions if you are using Reader. Reader Extensions is not required if you are Acrobat.
Ahh, perhaps fixed list will be ok for version 1

Question for the experts on Video problem

We are away on holidays but didn't want to miss this opportunity to ask for help from the experts. I'm not sure if I have a problem with my motherboard or video card or both. I posted the problem previously but here it is again.
I have an HPE-250f HP desktop computer which has worked well although has not had a lot of use. Shortly after purchasing it I got a real deal on a 17" i7 laptop which has been used much more than the desktop. Yesterday numerous Windows updates were installed and a couple of reboots to complete the installations. On occasion in the past Windows updates have caused issues but am sure they are not the cause of the current problem.
Upon turning on the computer yesterday it sounded like an airplane taking off so pulled the side cover off and it was the fan on the video adaptor that was making all of the noise. I have never heard it anywhere near that loud in the past even when under very heavy usage. In addition there was no video signal so my first thought was the adaptor had died. I took the adaptor out and reinstalled it to make sure it was seated properly however no change. I took the adaptor out again and then uncapped the VGA and DVI connectors that are on the rear of the computer but I did not get a video signal from either of those two outlets either. I don't know whether those ports are enabled on the motherboard or in the BIOS as this computer came with an upgraded video card. Either way there was no video. I have another low end video card here that I don't think was ever used so installed it and again no video. The hard drive seems to be making the normal sounds you would hear when it is booting but again with no video can't really say what is going on.
I am sort of out of ideas as to what to try next as without video you can't see if there are any error messages coming up, whether it is trying to boot or is actually loading Windows.
I don't want to scrap the computer and I guess an option would be to try and find the same motherboard and replace it but I am hoping someone may have some suggestions as to whether there should be video from the built in ports that come capped from the factory. It just seems odd that there is no video from the original card, the built in ports, or a different video card. It is also odd the original video card fan funs flat out when you turn the computer on before it even starts to get warm. If there is a problem with the slot the card goes in one would think the built in ports would still have video but that is assuming they are actually enabled but again don't know if they would be.
If anyone has any suggestions or if anyone knows a reliable place to buy the same motherboard that is in this computer I would appreciate that information.
Thank you

Finally back from vacation and took a bit of time to get caught up from vacation. It appears somehow two threads got started so will continue on with this one as there is more activity here. There is no video from the original video card reinstalled in the computer. There is also no video on either of the integrated ports after removing the caps and removing the battery, and tried two different monitors just to be sure. I have a friend with the same computer and he said there is no setting in the CMOS/BIOS to enable the onboard video so don't know if it has been permanently disabled or not but again no video from either of the integrated ports. Also If there is a speaker on this computer they have done a very good job of hiding it and i have never heard it beep in all the time i have owned it. I know at this link under INTERNAL CONNECTORS it mentions a speaker connection. I would install a speaker for the purpose of troubleshooting but I cannot find a reference anywhere that says which pins are for a speaker so if anyone would know where to find this information I would gladly install a speaker so we could troubleshoot further. http://support.hp.com/us-en/product/HP-Pavilion-Elite-HPE-Desktop-PC-series/4162190/model/4262654/document/c02014355 It is certainly a possibility that one of the updates caused an issue but it would be surprising as these were updates to Windows and not the BIOS, so one would think if the update was causing an issue it would be after the POST and when it was about to start loading Windows. I will try the suggestions listed above to the extent I can without a speaker connected but it would be great if someone can post a manual for the motherboard that mentions which pins or header has the speaker connections so I can install a speaker. I just heard back from my friend that has the exact same conputer and his has no audible beep when it starts either and am sure there is simply no internal speaker on this computer. Thank you

Retriggerable AI questions for the experts

I am using a PCI-6111 and would like to acquire 2048 points at 5 MHz triggered at 100 Hz. I am trying to use DAQmx.
Question 1:
I downloaded the retriggerable pulse train generation example for analog input and it seems fine except that I need an analog trigger and the counter trigger only allows digital. I modified the code (see attached) so that the analog input task has an analog trigger and then tried using AIStartTrigger as the source for my digital trigger for the pulse train generation. This works sometimes, but not others. Annoyingly when it doesn't work I receive no errors. The check for available samples always returns 0 and I can see the counter is not triggering on a scope (well it changes level once, but never generates a pulse train). I searched around and found another example posted (http://forums.ni.com/ni/board/message?board.id=170&message.id=189503#M189503) where a dummy analog output task is created to get an analog trigger. Instead of using AIStartTrigger they use AnalogComparisonEvent. Using AnalogComparisonEvent in my code instead of AIStartTrigger (but still in the AI task) seems to work fine. Is there a reason I shouldn't be using AIStartTrigger?
Question 2:
It seems that if my buffer is too small I get a similar sort of problem. That is, I receive no errors, the available samples always return 0, and the counter never triggers. In the retrig pulse generation example there is a cryptic remark about making the buffer 1000 points bigger than you need. I find I generally need something more like 10x points if I purposely try to slow down the system by moving a window around, for example. My question, though, is why do I not receive an error message and/or is there something I can check that will tell me there is a problem? I think the problem has something to do with the buffer being overwritten before the first check, but I'm not sure...

Hello Phamton,
To answer your questions:
1. I know that using the AnalogComparisonEvent is the typical way to trigger a counter off of an analog signal. The is the generally recommended method because the AnalogComparisonEvent comes straight from the analog comparison circuitry, however, the ai/StartTrigger signal should also work to start your counter task. If this approach was not working sometimes, I would first suspect the signal that was connected to the trigger line, and whether or not it was actually meeting the trigger condition at those times. Have you tried connecting a scope to the analog trigger signal when your program is not working?
2. I'm not sure of the exact reasoning for that comment in the example code, but even still, if you task is not starting, I would first suspect the actual analog signal that is being used as the trigger. Connect it to a scope and make sure that it is meeting the trigger condition when you run that program.
In any case, if your analog input task never receives the start trigger, you should get a timeout error. Let me know if you have any further questions about this issue.
Best regards,

Question for the experts... Two ISP's, one home network

OK, I am about to give up on the EA2700... It has been a small nightmare that has cost me time and money.
A bit of background here... We live way off grid, so far that being wired to it is not going to happen in my lifetime. We generate our own power from our own small hydro-electric plant on our creek. We have two internet connections, (three if you include tethering to the phones) and have been manually switching between to two. They are Hughesnet satellite and a line-of-sight ISP.
Here is my question: What is the best router out there for joining the two ISP's?
We had a network guy up to our place last year and he used the "netsh" command in DOS on each computer in the network. It worked for a while but I have a feeling this may have been a contributing factor in the current troubles we're having with the EA2700. We have removed two of the older PC's that had these command lines and have added a new laptop and tower, both of which we attempted to replicate the netsh command on but without success... Yes, a noob at this stuff...
I'm in the city today and am wanting to purchase the right unit before I head back into the hinterland. Thanks!

If you are planning to join two ISP's, you need a dual WAN router. EA2700 can't handle that. You might want to check this RV042 from Cisco.
If everyone needs to believe in something, I believe I'll have another beer..

Question for the experts!

Hi! Please can you save my life one more time!?
I had a whole number of projects saved to an external hard drive.
I tried to copy them to another one and eventually took both hard drives to a store to copy for me.
It took them about a week.
In that time I suspect iMovie has updated itself on my mac.
(It is also possible that I put the iLife package on that week - I doubt it, but it may be possible)
Anyway - now I have plugged my original external drive back in to my mac and tried to work on some of the projects.
It loads them up, with a lot of "ignore this" screens and a note sayiong iMovie has been updated and that opening this file now will make it unreadable for any older versions of iMovie. I clicked yes, 'cos I figured that if it was updated then it was always going to be that way.
Thenimovie opens the project with absolutely nothing to see in any of the panes!!!
I deeply suspect it pushed all the stuff into the trash, but I can't prove it!
How can I sort this out? Pleeease help!
Thank you!!
Karen

Hi Karen - are you sure that the store did not mess things up? It seems to me that your projects are missing the Media folders.
Have you tried opening them from your other drive - the one they copied to?
To check out my theory, open one of the project folders stored on your original drive. In there should be a Media folder. Open that if it exists and see what is inside.
Note that although you have converted your projects to a newer iMovie version, they will not yet be genuine iMovie HD projects - they will still be contained in a folder just like the earlier version. If you open one of these projects and 'Save As', it will be converted to a genuine new version, which is contained in a 'package' rather than a folder. Its contents cannot be exposed by double-clicking (that actually opens the project). But until you have solved your more pressing problem, let's just leave it at that.
By the way, I hope that both of your external drives are formatted correctly for Mac computers? They should be Mac OS Extended.
Let us know how you get on!

? for the experts regarding the HP Pavilion dv7t Quad Edition (with the new Sandy Bridge CPU's)

Hello,
This is a question for the experts.
The HP Pavilion dv7t Quad Edition has the following GPU:
1GB ATI Mobility Radeon(TM) HD 6570 graphics
Is this GPU GDDR5 or DDR3 in this laptop? I know someone that purchased one from a MicroCenter and it shows GDDR5 on the packaging (http://www.flickr.com/photos/bravoexo/5298674802/) and in GPU-Z, but I called HP support and they said it was DDR3 (although, HP support told me that GDDR5 didn't exist and that DDR3 in GPU's were the most advanced to this date).
Please let me know ASAP, as this is a main factor in me purchasing this or not. I can find other DDR3 gaming laptops out there for less, but if this really IS GDDR5, then I'm sold.

Thank you both for your questions and answers, I was wondering the exact same thing. I'm ashamed to admit I already began the process of perchasing this computer prior to having all detailed specifications made available.
I'm upgrading from a 13.3 inch HP laptop called the dv3510nr. It was never intended for enthuiast gaming, but it has exceeded the sum of its parts. It does have dedicated graphics, backlit keyboard, other novelties that make it the best computer I've personally ever owned.
Few people can say they've managed to run Fallout 3 or Supreme Commander at maximum detail on a 9300M GS. It has 512 MB of DDR2 memory, 4 GB system memory and a 25W P7350 Core 2 Duo processor (2.0 GHz)
Its served me well but mobility is no longer a priority. I waited until Sandy Bridge was announced and took the plunge immediately. 6 GB of DDR3 RAM, a 6570 with 1 GB, 1600 x 900 display AND best of all:
-The i7-2720 quad core processor, (2.2 GHz, up to 3.3 GHz with Turbo Boost)
--for a total price of just over $1,000 after taxes. With 2 year warranty standard.
For brand new, bleeding edge technology not yet even widely available, at such a large upgrade margin at an absurdly low price; I didn't need to know anything else.
So imagine my excitement when I learned this 6570 was in fact based on the old 5770 (the lowest available card with GDDR5 support), not the 5650; and could contain a 1 full GB of the fastest memory technology on the market, GDDR5.
That would mean virtually no bottlenecks in my system as a whole; I don't have an SSD but truth is, I don't like them anyway. They don't last very long with 'wear leveling', cost too much and only impact synthetic benchmarks.
My new DV7 can't get here fast enough.

I have a new email address and my old email keeps coming up on icloud when trying to update apps and i don't know the password or security questions for the old email. I can sign in with my apple id which is tied to another email but not itunes how to fix

I have an apple id and it has my current email attached to it. however when i go to update apps it's asking for the password for an old email. I no longer have the old email and can't use it. when I go to icloud on my ipad it asks for the password for old email. it doesn't allow me to change the old email to current. when i go to reset it i can't remember the password or security questions for the old email so it doesn't let me go any further. How do I fix this? Do i need to call apple support?

I have the same problem - it is maddening. I rely on this iPad for work so this is not just an annoyance! The above solutions of changing the appleid on the device or on the website do not work.
The old email address no longer exists - I haven't used it in a year probably and I no longer have the account. I logged into the appleid website and there is no trace of the old email address so there is nothing that can be deleted or changed there. On the iPad there is no trace of the old email address so nothing can be deleted there either. I have updated the iPad software and the same problem comes right back. Every 2 seconds I am asked to log in using the old non-existent email. The device is currently useless.
The only recent change to anything was the addition of an Apple TV device, which was set up using the correct login and password.
Does anyone have any ideas? The iPad has been backed up to the iCloud so presumably it now won't recognize the current iCloud account? So restoring may notbe an option?

Email Issues for the Experts

1) Why, when I have previously viewed items in my Inbox, leave the Email app, and return, do those inbox items simply VANISH before my eyes? This started happening on the iPhone 4 and never happened on any previous version.
2) Why is there a "Sent" and a "Sent Messages" folder? Why not just one or the other?
3) Why do NEITHER of those folders ever have any sent items showing in them???
4) Why, when I take a photo in portrait mode, does it end up in the inbox turned to landscape mode?
5) Advanced mail settings: "Sent Mailbox > "On my iPhone" and "On the server". This screen makes zero sense to me and there is zero helper text to explain what its for. I have "On my Iphone" checked. Logic tells me this leaves sent items on my iPhone. Yet there is nothing in the Sent folder.
6) Advanced mail settings: Same exact question for the Drafts and Deleted Mailbox ....
None of these items make sense. Please help.
