Is Practical to use ODBC over high speed intenet connections?

I am developing an application using Oracle 10g as back- end and Visual Basic / Access as front-end. ODBC works fine in intranets for this purpose, but I wonder if it will work over high speed internet connections to manage several offices from the headquarters.
Any information on the subject will be appreciated.

Connecting and using database connections over a WAN can be very slow. There are usually several network conversations for even the simplest SQL statements. An application that is used to querying the database each time it needs data can be brought to its knees when the latency goes up, regardless of how much bandwidth is available.
As long as the latency is less than 20ms, you probably won't notice too much. Once it goes over 50ms, you start to curse these database companies that don't use real streaming. At 100ms or more you start thinking that Citrix is the best invention in the world.

I do not have a high speed internet connection. How can I get Mountain Lion on a disk for install on my 24" Imac?

As long as you use your Apple ID to purchase it, I don't see why they wouldn't let you download the installer on one of their Macs and put it on a pocket drive.
Or, a friend with a high speed connection?
I agree with you about the delivery method, just trying to help you get what you want.

Wireless high speed internet connection

I would like to know if somewhere we can find a kind of PCS card for wireless high speed internet connection, but for power books and iBooks G4?
I'm living in mexico City and one company (iusacell) is offering the service but just with PCS cards for PCs, but no for macs.

Unfortunately, the 12" PowerBooks and both size iBooks lack the required PCMCIA slot for such cards, so they cannot be used at all.
The 15" and 17" PowerBooks do have a PCMCIA slot, but if your network doesn't supply Mac software or drivers, it probably can't be used.

What is the best way to connect my ipad to the high-speed Internet connection in a hotel room

what is the best way to connect my ipad to the high speed inernet connection in a hotel room

every connection is a bit different. Generally, connect to the wifi, then you may need to open Safari, and may even need to try to get to one of your bookmarked pages to trigger the 'agree to our terms' page to come up.
As to it kicking you off every so often, there are sometimes glitches with the wifi on iPads, you can also be subject to any programming the hotel has. Like I've noticed various places that only allow you to log on for a period of time before having to relogin.
most hotels have 1-800 numbers, so you can always try calling that to see if their tech support has any tips for the frequent disconnection issue.

Is UNITE-CB1B @ 4G considered a high speed broadband connection? My Macbook does nothing well

Is UNITE-CB1B @4G considered a high speed broadband connection. I've tried three times to download Mavericks and no go. Is it my Macbook or my Wifi? If it's my Wifi, I guess I'm just screwed. Very down on Apple right now.

Make sure your MacBook Pro meets Mavericks requiremennts > OS X Mavericks: System Requirements
Mavericks is a 5.35GB file and requries a high speed broadband connection and requires 8GB or more of available disk space.
Backup all important files before upgrading
Checked to see how much space is available ??
Click your Apple menu  top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space.
You can test your download speed here > Speedtest.net - The Global Broadband Speed Test
Download speeds less than 10Mbps may time out before the 5.35GB file can download.
Keep in mind, after installing Mavericks, if at some point you need to restore OS X or repair the startup disk, that requires a broadband connection as noted here > OS X Recovery

How to use PCI-6534 High speed DIO to count the no.of pulses aquired

HI All
I have PCI-6534 high speed DIO card. My requirement is to count the no.of pulses coming. Here i have an energy meter which generates pulses with frequency of around 8MHz. i need to cunt the no. of pulses coming in, here i am attaching the VI i am using. I could not really count all pulses coming in. right now i am using single line, but the requirement is to develop for 7 lines. I do not know where i am going wrong. Can any of you help me in this regards.
Thanks

Sorry, not near a LV PC so can't look at your vi now. Are you limited to using only the 6534? If all you need to know is the count of pulses from each of the 7 ~8MHz sources, it seems like the amount of data storage required with a 6534 is terribly inefficient. Since the 7 sources are unlikely to be synchronized in any way and they are each at ~8MHz, you're looking at about 100+ million transitions per second with change detection. I don't think the hw can keep up with that. Even using a constant sampling rate of 20 MHz (which just barely satisfies the Nyquist minimum of 2x 8MHz), it's questionable whether you can keep up with that rate for several minutes. Even supposing the hw and your PCI bus and software can keep up, there's still a TON of processing to do. 20 MB/sec for 20 minutes = 24 GB!
On the other hand, consider the 6602 counter timer board. Here you would simply set up 7 edge counting tasks, probably without any buffering at all. At any leisurely pace you want, you can software query the counts of the # of pulses on each of the 7 channels and have an instant answer. The only issue to deal with is that the counts will rollover when you reach 2**32. At 8 MHz, this will happen about every 9 minutes. However, DAQmx provides a nice way to handle this. There's a property you can query that will tell you if a rollover has occurred. It automatically resets itself to False after you read it so it's ready to detect the next rollover 9 minutes later. See my first post in this thread for example. (Last I knew, only DAQmx does the automatic reset, not traditional NI-DAQ).
If you can possibly buy a 6602, I'd highly recommend it.

How can a session be setup between two MacBook Pro's at different locations on high speed Internet connections, be setup to have a live recording session in Logic?

My partner and I live on opposite sides of the valley here in Phoenix. About 50 miles apart one way. We are Musicians and are working on a commercial for television, and would like to know if there is a way, between FaceTime and Logic, that we can configure our MacBook Pro's to record sessions together without having to be at the same house? When we FaceTime, he can hear my keyboard through his headphones, but we can't seem to get the signal routed into Logic and register to a track when its record enabled. Is there a way for us to save gas, and record at seperate locations, so he can engineer me and I can engineer him, while we build this project in Logic and Final Cut? Here is what we are using, we have nearly identicle setups, which was planned so we might be able to do something like this. Both of us are using Mid 2012 15" MacBook Pro's with 2.6GHz Intel i7 processors and 16GB RAM. The only difference between the two MacBooks is that his has an Optical Drive, but I removed mine and replaced it with a 2nd SSD Drive, so I have two Samsung 840 Pro's each with 512GB in my MacBook Pro. His just has one Samsung 840 Pro with 512GB. We both use Focusrite Saffire Liquid 56 Firewire Audio Interfaces, and we both use Logic Studio 9 Academic. I don't know if you need to know what we are using in order to help us figure out how to configure the MacBooks for a live session, so I figured I would give you those details just in case. If you need any more information, just let me know? Oh, we both have high speed cable Internet connections. Mine is 150Mbps speed which is the absolute fastest I can get in my area. And his is only a 50Mbps speed line.
Again, what we are looking to do is have a LIVE recording session, in Logic, with him at his house and me at my house. When we FaceTime each other, we can pretty much hear each others keyboards as if they were part of the conversation, and as crystal clear as we can hear our own when recording, but we can't seem to record enable an Audio track in Logic and route that keyboard signal into Logic and record it so we can engineer each other without either one of us having to drive to the others house, to be there to do it. If any of this even makes sense, I'm not quite sure how to better explain it. So hopefully you get what I mean, otherwise just say so, and I will try to do a better job explaining it. :-)
Anyone who can help us with this little problem would be greatly appreciated, and quite a hero in these two humble Musicians Worlds!! So from both of us, THANK YOU in advance for any input you might be able to give us. I look forward to hearing any and all suggestions.
Scott

Hey Scott
You and ALOT of people are attempting to do this, myself included.
Unfortunately at this point (to my knowledge) it's a pretty CRAP setup involved that will likely leave you frustrated.
HOWEVER:
A few things CAN be done:
IF you are getting live audio from your partner over the internet, you can re-direct that audio directly into Logic using a program called SoundFlower.
There are a few alternatives to SoundFlower, like JackTrip, and.....(the name eludes me)
(SoundFlower is from a company called Cyling 74 who also makes Max MSP. )
Once in Logic, you set your audio inputs to the track to be Soundflower. (either 16 inputs, or in this case 2)
That all being said, regardless to speed, you are still going to experience latency in the connection, and THAT is the part that will likely drive you to the mad house.
THIS all being said, I believe there are websites out there that are set up to actually do this kind of thing, (at least there WERE) but likely membership costs, and other "hidden" problems that you only learn about after you have signed on the dotted line. (Hopefully I am wrong?)
If you don't need to do a "live jam", there are always solutions like DropBox that work very well for exchanging large files quickly.
If you want to record live MIDI input from his keyboard, I am unaware of any solutions for this.
Due to the popularity of the iPad, you might want to look into the App store, and see if there is something available.
Good luck!

Options for high speed internet connection. . .anyone tried Directv?

Just relocated to a black hole of communications. . . Sprint telephone provider does not provide high speed service in my area. Town about 10 miles away has wireless access but not good for me. . . have new intel 20" Imac and now using apple external modem. . .good connection with aol but slow and would like to do better. I have Directv which is persistently touting their internet service. Anyone have experience with that? What are my other options, if any?

I have had DirecWay (soon to be HughesNet) for a year. I have the Pro account ($69/mo) with 1000/200 kb/s D/U and a 350MB download bucket which refills at 56 kb/s. That is about 350 MB per 16 hour period. It has been reliable. Heavy snow will stop like with DirecTV, but with dish low enough to sweep the snow off corrects this. Speeds vary, but is always better than dial-up. We had 18.8 kb/s on a very good day with dial-up.
However! The latency is high, 700-900ms. This delay is annoying, it takes a few seconds before your page come up. "Twitch" games don't play well. Other than that it is great.
I kept waiting for DSL or anything but it never came. My only regret is that I should have gotten it sooner.

MS Access .mdb connection using ODBC could not resolve the connect identifier ORA-12154

Dear All,
I'm trying to use MS Access .mdb file as source to my OWB application. I need to connect to the ms access .mdb file first using odbc. Here are the step I do:
1. Define ODBC connectifity
     control panel -> admin tools -> data sources -> System DSN -> Add
     Choose Microsoft Access Driver (*.mdb) -> Finish
     Data source name: msaccess -> Database: Select -> .mdb file location (C:\MSAccess\att2000..mdb)
2. Configure Listener
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    (SID_DESC =
      (SID_NAME = msaccess
      (ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = hsodbc)
LISTENER =

      (ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = hsodbc)
ADR_BASE_LISTENER = C:\app\Administrator
3. Configure Oracle HS
     File name initmsaccess.ora
# HS init parameters
HS_FDS_CONNECT_INFO = msaccess
HS_FDS_TRACE_LEVEL = 1
# Environment variables required for the non-Oracle system
#set <envvar>=<value>
4. Edit tnsnames.ora
msaccess=
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SID=msaccess)
      (SERVICE_NAME=msaccess)
(HS=OK)
5. create database link
create database link msaccess using 'msaccess';
6. Run a query to test connection
SQL> select * from departments@msaccess;
ERROR at line 1:
ORA-12154: TNS:could not resolve the connect identifier specified
I check the tns using tnsping msaccess, it return

High Speed DSL connectivity issues.

Hi. I have connectivity issues with the High Speed DSL internet connection. I have had internet service with you guys for almost a year now, and since day one, I have had connectivity issues. In the past, the connection would drop once every few days, and about once every two weeks I would need to restart the modem in order to get my connection back.
I have restarted my router countless times, and even done a factory reset on the router a number of times as well.
The past two days, my internet connection has been worse than ever, with the connection being dropped about once every five minutes. And, while the connection was up, my browsing, video, and email loading times were very slow.
The internet light on the modem is constantly flashing, even when I am connected.
The gateway status info page refreshes 4-5 times a minute.
I dont know if any of the following info will help. I would like to continue with Verizon as my ISP, but if the connection issues continue, I will have to change services.
I have the Actiontec GT708WNV modem.
The gateway status info is:
Gateway ParameterStatus
Firmware Version:
GT784WN-VZ-1.1.6
Model Number:
GT784WNV
Serial Number:
{edited for privacy}
WAN MAC Address:
Downstream Rate:
13759Kbps
Upstream Rate:
1027Kbps
PPP User Name:
N/A
ISP Protocol
1483 via DHCP
Encapsulation:
LLC
Gateway IP Address:
DNS Address #1:
DNS Address #2:

Step one: Visit http://www.giganews.com/line_info.html and post up the Traceroute the page shows, if you wish. Be aware that the final hop (bottom-most line of the trace) might contain a hop with your IP address in it. Remove that line. What I'm looking for is a line that mentions "ERX" in it's name towards the end. If for some reason the trace does not complete (two lines full of Stars), keep the trace route intact.
Step two: Can you provide the Transceiver Statistics from your modem?
As to where that is, it seems to be at
STATUS > WAN STATUS.

Best Practices when using MVMC to improve speed of vmdk download

I've converted a number of machines already from ESXi4.1 to Hyper-V 2012 successfully and learnt pretty much all the gotchas and potential issues to avoid along the way, but I'm still stuck with extremely slow downloading of the source
vmdk files to the host i'm using for the MVMC. This is not so much an issue for my smaller VM's but it will be once I hit the monster sized ones.
To give you an idea on a 1GB network it took me 3 hours to download an 80GB VM. Monitoring the network card on the hyper-v host I have MVMC running on shows that i'm at best getting 30-40Mbs download and there are large patches where that falls right down
to 20Kbs or thereabouts before ramping back up to the Mbs range again. There are no physical network issues that should be causing this as far as I can see.
Is there some undocumented trick to get this working at an acceptable speed?
Copying large files from a windows guest VM on the esx infrastructure to the Hyper-V host does not have this issue and I get the full consistent bandwidth.

It's VMWARE in general is why... Ever since I can remember (which was ESX 3.5) if you copy using the webservice from the data store the speeds are terrible. Back in the 3.5 days the max speed was 10Mbps as second. FASTSCP came around and threaded it to make
it fast.
Backup software like Veeam goes faster only if you have a backup proxy that has access to all data stores running in VMware. It will then utilize the backend VMware pipe and VM network to move the machines which is much faster.
That being said in theory if you nested a Hyper-V server in a VMWARE VM just for conversations it would be fast permitting the VM server has access to all the datastores.
Oh and if you look at MAT and MVMC the reason why its fast is because netapp does some SAN offloading to get around VMWARE and make it array based. So then its crazy fast.
As a side not that was always one thing that has pissed me off about VMWARE.

Using NI6587 in high speed mode 1GS/S in parallel mode

Hi
We use the NI6587 + PXI-7952R
I am looking for examples of program of using this configuration in high speep Mode (1Gs/s). I want to acquire a bus of 8 bits from a ADC device.
Thanks for your help in advance,
Sebastien

Papa,
There is a good instruction set on getting everything up and running. Not always the easiest to find if you don't know what you are looking for though.
Start with the FGPA Module Installation Guide. This walks you through the hardware install, making sure the FGPA module is installed and so on.
Make sure you have the NI FlexRIO Adapter Module Support installed. This gives you examples to work from. That link is for version 3.4 (I believe the latest).
From there, reference the NI 6587R User Guide and Specifications. It has a good walk through of creating an FPGA project and working with the device.
Hope this helps!

please help me guys

No, there is no work around. Facetime over cellular requires at a minimum an iPhone 4s, and that your carrier support the feature. Sorry, but the requirements are what they are.

Installing Sprint Broadband High Speed Internet Connection

I am getting 11bps internet connection with my dial-up server, AOL.
Sprint has sent me the materials that are, for a huge price of $69 a month, supposed to give me broadband speed which I simply must have in order to attend online art classes which I am beginning next week.
Does it make any difference if I insert the disk before the laptop is turned on, or if I insert it while the laptop is already turned on?
I am totally scared to death to do this. I'm afraid something will go awry and I will screw things up. Any one here who has been through this? And knows the possible pitfalls? And can guide me through it?
I've read the printed instructions through 3 times and they are NO help. They are not clear or informative, so that I feel sure and secure of what to do and what to do next. I am floundering....and the clock is ticking! Help!
Cyan

Hi Cyan,
No worries either way on the disk, but no benefit of having it in first... you must still be a little bit stuck in the Windows® universe!
There'll be an installer once you open the CD, but it won't boot your Mac like some PC stuff does.
In fact, I think you/we can set it up without their CD even.
Seriously, don't worry yourself on this, it'll be easier than the documentation, and if that weren't enough, if I or others can't help you, I'll put out a Bat Signal for the best AOL helper in the whole world... Ali B., and help is but a parsec away.
