Too many usb comm ports
Good Morning,
I've run into what may be issue soon, where we have the units being tested that have built in USB ports that appear as serial comm ports. The problem is that every time we connect a UUT that hasn't been run on that computer before Windows assigns it a new com port number. My concern is that quite soon, as the production line gets into full swing, we will hit the "magic number" of 255, the highest com port number and I don't have any idea what Windows will do at that point. Before I start writing code to parse the new com port number returned by VISA, and adjust" the registry entries accordingly, I want to know if it is necessary. I figure that there are a couple of possible scenarios, that Windows complains and won't issue a com port #, that Windows starts over at the beginning, or that Windows just hits 255 and then keeps reissuing it. I would prefer that it be the later two, don't want to have my program messing around in the registry, and really don't have time at the moment, nor access to the machine(s) to experiment to see.
Thanks,

Solved!
Go to Solution.
I'm not sure that I understand your answer. The problem is that on our test stands we will see hundreds of the product boards go by over the life of the boards. As I have seen with "standalone" usb-serial adapters, when a new one is plugged in, that the computer hasn't "seen" before, it will assign it the next available comm port #. It probably knows that it hasn't seen it before by some serial numbering type scheme that is returned in the USB's header info when plugged in. As the hardware design for the unit containing this USB interface is essentially frozen, and as that side of the design group won't see it as a problem in the target systems (where the boards won't be "talked to" via the USB path) it is unlikely that I can get any hardware/firmware changes. I'm not sure that would be the way to go anyway. Definitely not going to get a change to the BOM at this point (on top of which I'm an outside contract test consultant). So I will have to address the problem on my side of the fence. I haven't looked yet, but am pretty certain that the Com#'s are stored in the registry, so I can just make sure that I "reset" those numbers before they get to 255, but am never comfortable with my programs modifying the registry.

Ipod disconnects when too many usb devices are connected?
i have a gigabyte 7VTXE motherboard, the right via drivers and XP sp3
usb devices where it works:
keyboard, mouse, ipod
if i connect a hauppauge USB tv box or my speedtouch ADSL modem, it disconnects sometime soon after
has anyone else heard of this? annoying isn't the word....You may be exceeding the total power available on the USB bus. If that is the case, one solution may be to get a self-powered USB hub. Connect the iPod and other devices that are frequently connected and disconnected on-the-fly to the hub. This will also reduce wear-and-tear on the more valuable USB ports on the computer. You can always get another $20 USB hub. Make sure it is the type that has its own power supply.

Solving Prolific PL-2303 USB to Serial Comm Port installation issues
Hello everybody,
More and more machines are comming without Parallel and serials ports, they are comming with USB external ports only.
Some have the RS-232 and Parallel headers in the motherboard, and that should last for about a year I think.
At any rate, the issue I was facing is the following:
(a) Installing Prolific PL-2303 USB to Serial Comm Port on Windows XP Pro SP3 works OK and system runs fine. there are some capacity issues regarding the buffer size, but that is another post.
(b) Installing on WEPOS 1.1 SP3 on some motherboards (Older ones) that have at least the Parallel headers and a serial port, the device also works as with (a)
(c) Installing on WEPOS 1.1 SP3 with a machine with only external USB's (no parallel / serial port or headers). The installation process runs OK. but when the device
is plugged I get the following error message:
"An error ocurred during the installation of the device"
"A service Installation section in this INF is invalid"
(d) Installing on POSReady 2009. I get the same as with (c)
This is how I solved, after many frustrating reboots with the same message about the INF section and multiple Prolific drivers tried. I started digging windows:
(1) Find the setupapi.log and read it, if the OS is a fresh install it will not be too long.
(2) Read this:

(3) So it was the serenum.sys file that Windows needed to find in the ..\system32\drivers folder. I got the serenum.sys from one of the temporary folders created by the installation process.
(3a) So, I think that windows installs this sys file if it recognizes the motherboard has at least one parallel or serial port.
(4) So good luck when installing your serial device to your POS solution. I will open another thread if I have problems with the buffer size of the device.
Humberto SequeiraHello Terry,
Indeed, they were not intended as POS system, the EEE Top machines are candy to the eye, but for my taste they do not work in POS environment (I give them 1 year before they pop). Regarding the other, well competition is tought, so you have to get creative in order to keep costs down, and this one can be used as a waiter stations, that do not need heavy serial comunications.
Anyways, the POSReady does not install these system files if the installation does not detect a serial or parallel port (which make sense, as why would it install drivers for a device that is not detected). I posted this for others to be aware of this when they select the hardware that will be offered to their customers, as good old "on mother-board" serial and parallel ports cannot be beaten by their USB imitations (IRQ and memory addressing processing are needed for end devices to function properly).
Have a great weekend,
Humberto -
Why can't you provide specific instructions here in HT203909 (Boot Camp: Creating an ISO image from a Windows installation DVD) about how to make the USB drive bootable? The article referenced for partitioning the drive is not dedicated to Bootcamp--too long, too many options. How do you make it bootable?
If your BC Assistant shows the option to create a USB Installer, it automatically is marked as bootable. There is no need to have manual intervention to make a bootable USB. Once the process is manually modified, it is supported by the person modifying it.
You have two or three options (depending on your Mac Model).
1. Create USB... - Use a USB2 flash drive, which is erased and formatted. If your Mac supports ISOs then BCA will prompt for the Media. Any Mac which does not have a built-in Optical drive will support an ISO. There are specific Mac models which support both, DVD and USB based installation.
2. Download Software from Apple servers...
3. Install Windows...
Are any additional instructions really necessary? -
How many usb ports (if any) does the 30 inch display have?
I am getting the new mac pro I know apple is going to kill the 30 inch display but as they have not done so yet I was wandering how many usb ports does it have?
Hi macnewcomer22,
Instead of buying the Apple 30" Cinema Display, for not much more you could buy the NEC Multisync 3090WQXi, which incorporates later technology and was awarded Best in Show at MacWorld.
The Apple 30" is a good display, but the technology is about 5 years old, and later models from other manufacturers, noticeably NEC, have surpassed it:
http://macperformanceguide.com/RecommendedDisplays.html
http://www.pcpro.co.uk/reviews/monitors/242010/nec-multisync-lcd3090wqxi
I purchased the standard Multisync version, without the Spectraview II software, in July 2009, and I have found it to be excellent in all respects:
http://www.nec-display-solutions.co.uk/p/uk/en/products/details/dp/Products/LCD/ Current/LCD-3090WQXi/LCD-3090WQXi.xhtml?e=e1s1
Although most resellers only stock the 3090WQXi in black, it is also available in a silver finish, which looks great alongside a Mac Pro.

VISACOM - Alloc Error using 488.2 USB-B Interface - too many open sessions
I have been having the following issue in my VB .NET RF-ATE application.... It usually happens when my program enters a measurement loop (I.E. searching for P1dB). It begins to solve for P1dB and performs about 15 cycles (sets power level on SigGen and takes SpecAn meas) and then crashes due to the following error :
As Logged in the Event Viewer :
VISA: May 13 09:45:22: Error=bfff003c,"VI_ERROR_ALLOC: Insufficient system resources/memory": ViTable::add - too many open sessions
As Logged in VB .NET :
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in RFATE.exe
Additional information: HRESULT = 8004003c
VI_ERROR_ALLOC
Not sure why its happening my code is pretty solid (or so I thought) and I believe it closes the VISA session properly after each R/W operation? (See attached). I call the same procedure to talk to the GPIB instruments over and over.
Is it possible that I am not freeing and disposing of resources properly? I have read a little about destructors in .NET etc. but I was under the impression that as soon as "Sub End" is executed that the resources were free'd up? But that doesn't explain why I would get a "too many open sessions" error occour if I am closing the session after I am finished?
Another odd thing to note is that I have created testplan scripts and loaded them into my application with literally hundreds of measurement commands and my program didn't crash then???
I am very new to VB and .NET (3 months) so I have a lot to learn but I can't understand why this is occouring. Any help is appreciated.

GPIB.txt 3 KBJust posting a followup... Turns out I found a way to make it work! (I have been fighting this for almost 3 days!).
If you look at the variable declarations of my procedure.....
Sub GPIB(ByVal Addr As Object, ByRef Data As Object, ByVal IO As String)
Dim ioMgr As Ivi.Visa.Interop.ResourceManager
Dim instrument As Ivi.Visa.Interop.FormattedIO488
Dim session As Ivi.Visa.Interop.IMessage
I use the "IMessage" interface for the variable session.
Just before the "Sub End" is executed I use the following line to close the session :
session.Close
Which it would appear doesn't close the session properly when you use the "IMessage" interface.
So I changed the line to use the "IVisaSession" interface instead :
Dim session As Ivi.Visa.Interop.IVisaSession
Now when the Close method is executed aparently it closes the session properly because my program isn't crashing at all!
I was using VISA COM 3.0 Reference object (GlobMgr.dll).
If anyone has any insight on this please do share. -
My ipad is disabled because of too many itemps and I tryed connecting to iTunes but it said nothing on the Apple Support page said it would. What do I do???
The answer is in the article. Finish reading the second part:
If you see one of following alerts, you need to erase the device:
"iTunes could not connect to the [device] because it is locked with a passcode. You must enter your passcode on the [device] before it can be used with iTunes."
"You haven't chosen to have [device] trust this computer"
If you have Find My iPhone enabled, you can use Remote Wipe to erase the contents of your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode after the device has been erased.
Alternatively, place the device in recovery mode and restore it to erase the device:
Disconnect the USB cable from the device, but leave the other end of the cable connected to your computer's USB port.
Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to shut down.
While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.
Continue holding the Home button until you see the Connect to iTunes screen.
iTunes will alert you that it has detected a device in recovery mode. Click OK, and then restore the device. -
Portal creates too many database sessions. fix doesn't work!!
Oracle Database 9i, Application Server 9iAS,
Operating System SUSE Linux 7.2

There is a modification for the http server that aims to eliminate a problem on unix that causes the database to create too many sessions. The script can be found at
http://portalstudio.oracle.com/servlet/page?_pageid=1787&_dad=ops&_schema=OPSTUDIO
However the script fails to work. The http server is on port 80 with the redirect on port 7778. However going to http://myhost/pls/ results in a server error - connection refused. Is it possible that there may be an error in the script.
Thanks in anticipationok so my sound is ok now I can check that off of the list... I just looked around and found some external USB speakers that work just right. My built in computer speakers are just not the best quality.
As for the microphone, I still haven't been able to find out what is causing it to not work. I notice that it isn't actually broken since if I make a really loud noise right next to the input it will register a little but only a little bit.

Where do I get the AC to DC Power Adapter for a Linksys "Compact USB 4-Port Hub [USBHUB4C]
I have two Compact USB 4-Port Hubs, Model Number USBHUB4C. These Hubs can be powered, but I cannot find any information on External Power Adapters for these Hubs in any of the documentation or on the Linksys Web Site.
I need to know if Linksys has such Power Adapters available, and if so what the Model Numbers are, and how or where to purchase them.
If I will need a third party Power Adapter, I need to know what the Output Voltage & Current requirements are, and I also need to know the Polarity of the of the two Jack Contacts. [i.e. Is the center pin on the Hub's Jack Positive or Negative?] If possible I'd like to have a recommended Brand and Model Number for the Power Adapter.
Thanks In Advance,

Hi, again,
Boy, am I glad I was able to find an answer to my problem in here. I find this very interesting. Here it is, almost 3 years after I made the original post, that I need to find the Power information, for this Device, again, but because of a Computer Crash, I could not get to the original notes, I made about this Forum Entry, so I began the search, again.
I find this very interesting. Here it is, almost 3 years after I made the original post, that I need to find the Power information, for this Device, again, but because of a Computer Crash, I could not get to the original notes, I made about this Forum Entry, so I began the search, again.
I have myriad AC/DC Converters, some of which are Voltage Selectable, but since the Power Specifications aren't on the HUB, or in the PDF Documentation, as is the case with most other Products, I came back to LinkSys/Cisco. As soon as I entered the Model Number of the "Compact USB 4-Port HUBs, Model Number USBHUB4C," for a search, this Forum entry came up on the page, and it appears there haven't been any queries, on any other subject, about this Device, in the interim.
Since the entry has been Viewed 2,484 times, hasn't it dawned on someone that it might be a good idea to carry a Power Product, that is compatible with this HUB, or at least provide a Specific Source, with a Model Number, (for instance, a Radio Shack SKU) so we don't need to hunt for one, over, and over. Why the information was never included in the package with the HUB, beats me. (It should have been on the Device, itself.)
Anyone who knows anything about USB Devices, knows that many of them cannot be powered from the USB Ports on a Computer, especially, on Laptops. Since one of the things mentioned in the Specifications is the fact that you can have "Max. Devices 127 (Daisy-chaining Hubs Together)," it would seem to be obvious that Power Information would be necessary. Since the "Daisy Chain" number is true, it should be obvious, that the "Chain" would require quite a few AC/DC Adapters to power it, adequately.
When this Device was Designed, the requirement for External Power must have been known, or there would never have been a Power Connector built into the Device. I've been in electronics for about 50 years, now, and I know that presently, it's a rarity that the Power Requirements aren't shown on the Device itself, with a Symbol depicting the Polarity of both the Inner, and Outer Conductors. Even Toys have that information shown on them.
I love these HUBs, but LinkSys/Cisco has really dropped the ball on this one. I'm guessing that a lot of people have discovered, that if this 4-Port USB HUB doesn't have External Power, they quickly decided not purchase another one, when they need to "Daisy Chain" them together, for their Network of USB Devices.
When you consider the loss of HUB Sales, coupled with a loss of income from a Power Supply they've never stocked, the numbers could be quite large. That's not even considering the Support time I'm guessing would have been necessary when Customers determined they had a problem, and needed answers. (It's not really a guess, since I talked to several Support People, without getting a satisfactory answer, before I finally came to this Forum, as a last resort.)
I was actually shocked to find that LinkSys/Cisco, didn't sell an AC/DC Power Supply for the HUB, because Power Supplies like that are so commonly required, with the Electronics sold, today. I'd be willing to wager that LinkSys/Cisco does, in fact, carry an AC/DC Power Supply that would be compatible with the "Compact USB 4-Port HUBs, Model Number USBHUB4C," they sell. When something like this happens, I wonder how many other Opportunities like this, have been missed by the people who work for this company.
We've all heard the expression about "Being too close to the Forest, to see the Trees." This may be a good example of it's meaning. At least I was able to find the answer to my Problem, thanks to the fact that the Query I made almost, 3 years ago, which had an answer, was still available to me, thanks to this Forum.
Very Interesting!

How you restore your security pass code if you have disabled your iPod, due to too many pass code attempts?
If You Are Locked Out Or Have Forgotten Your Passcode
iTunes 10 for Mac- Update and restore software on iPod, iPhone, or iPad
iPhone, iPad, iPod touch: Wrong passcode results in red disabled screen
iOS- Understanding passcodes
If you have forgotten your Restrictions code, then follow the instructions
below but DO NOT restore any previous backup. If you do then you will
simply be restoring the old Restrictions code you have forgotten. This
same warning applies if you need to restore a clean system.
A Complete Guide to Restore or Recover Your iDevice (if You Forget Your Passcode)
If you need to restore your device or ff you cannot remember the passcode, then you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and re-sync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone, iPad and iPod touch software.
Try restoring the iOS device if backing up and erasing all content and settings doesn't resolve the issue. Using iTunes to restore iOS devices is part of standard isolation troubleshooting. Restoring your device will delete all data and content, including songs, videos, contacts, photos, and calendar information, and will restore all settings to their factory condition.
Before restoring your iOS device, Apple recommends that you either sync with iTunes to transfer any purchases you have made, or back up new data (data acquired after your last sync). If you have movie rentals on the device, see iTunes Store movie rental usage rights in the United States before restoring.
Follow these steps to restore your device:
1. Verify that you are using the latest version of iTunes before attempting to update.
2. Connect your device to your computer.
3. Select your iPhone, iPad, or iPod touch when it appears in iTunes under Devices.
4. Select the Summary tab.
5. Select the Restore option.
6. When prompted to back up your settings before restoring, select the Back Up
option (see in the image below). If you have just backed up the device, it is not
necessary to create another.
7. Select the Restore option when iTunes prompts you (as long as you've backed up,
you should not have to worry about restoring your iOS device).
8. When the restore process has completed, the device restarts and displays the Apple
logo while starting up:
After a restore, the iOS device displays the "Connect to iTunes" screen. For updating
to iOS 5 or later, follow the steps in the iOS Setup Assistant. For earlier versions of
iOS, keep your device connected until the "Connect to iTunes" screen goes away or
you see "iPhone is activated."
9. The final step is to restore your device from a previous backup.
If you can not restore your device then you will need to go to recovery mode.
Placing your device into recovery mode:
Follow these steps to place your iOS device into recovery mode. If your iOS device is already in recovery mode, you can proceed immediately to step 6.
1. Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the other end
of the cable connected to your computer's USB port.
2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the
red slider appears, then slide the slider. Wait for the device to turn off.
If you cannot turn off the device using the slider, press and hold the Sleep/Wake
and Home buttons at the same time. When the device turns off, release the Sleep/Wake
and Home buttons.
3. While pressing and holding the Home button, reconnect the USB cable to the device.
The device should turn on. Note: If you see the screen pictured below, let the device
charge for at least ten minutes to ensure that the battery has some charge, and then
start with step 2 again.
4. Continue holding the Home button until you see the "Connect to iTunes" screen.
When this screen appears you can release the Home button.
5. If necessary, open iTunes. You should see the following "recovery mode" alert:
6. Use iTunes to restore the device.
If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
Additional Information:
Note: When using recovery mode, you can only restore the device. All user content on the device will be erased, but if you had previously synced with iTunes on this computer, you can restore from a previous backup. See this article for more information. -
Router connection problems - DISH satellite receivers or too many devices?
(Sorry about that - I thought I had broken the message up.)
I'm having significant issues with my Linksys router timing out, and need help. I'll try to be as detailed as I can.
I have the following:
- Linksys WRT54G v3 wireless router I purchased off eBay 3-4 years ago. Using 128-bit WEP secirity. Even though the model says WRT54G, my Linksys setup page says I have a WRT54GL. Don't know if that's pertinent but thought I'd include the info)
- HP desktop running Vista Home Premium
- Gateway Solo laptop (circa 3Q 2002) running WinXP SP3, and also have WPC54G - Wireless-G Notebook Adapter
- Gateway M275 Notebook running Windows XP Tablet Edition w/SP3, internal wireless card
- Linksys WRE54G Wireless Range Expander, v3
My broadband internet connects to my cable modem, which then runs via ethernet to my router. I have my desktop connected to my router via (wired) ethernet cable (port 1), and the two laptops connect wirelessly. All three computers on my network run just fine and have had no connection issues until I had two (2) DISH satellite receivers installed this past Friday.
Prior to installation, I knew I would need the two receivers hooked up to my network via ethernet cable. Since one receiver was in the same room as my router, it was easy to run an ethernet cable from my router to the receiver (port 2). I had a challenge with the upstairs receiver, because I didn't have a direct connection, and wasn't sure how to wire it. So, I used my range expander by plugging in the expander into a nearby outlet, then connecting the receiver to the expander via ethernet cable.
I had some issues getting a good signal, and did some troubleshooting but made it work. Now I had five devices connected to my router: two with a wired ethernet cable and three wirelessly.
I started having connection timeouts within about 3-4 hours of satellite [receiver] installation. All of the sudden I couldn't connect to the internet on ANY device; both laptops couldn't connect wirelessly, my desktop couldn't connect, and the receivers were telling me my connection was bad. I checked modem but there were no issues. Still, I unplugged the power cable from the modem for a minute, then reconnected - still no internet. I called my cable company to have them troubleshoot the modem, but they pinged it several times & got positive results - still no internet, so I ruled the modem out.
I tried using the Windows connection troubleshooter to repair the problem, and got a DNS error message (which I don't know how to fix). I decided to unplug my router for 10-15 seconds, then plug back in - that got my internet connection going again. That lasted a couple hours & then failed. I unplugged the router again (is that a soft reset or a power cycle?), then reconnected & was able to connect to the internet. This happened a few more times over the weekend, and finally I decided the expander might be the issue (both DISH and Linksys tech support was not very helpful).
I found a way to wire my second receiver via ethernet cable (port 3), so now I had three wired devices, and two wireless devices. I thought this would fix the problem; it didn't, but at least I learned how to wire CAT5 cable. So I got that going for me... which is nice.
I plugged the ethernet cable directly from my modem to my desktop to test the timeout, but had no issues - the modem just wasn't the problem.
I was getting some IP address conflicts on my Norton Inernet Security, so I uninstalled that from my desktop, disconnected the power from the modem, disconnected the power from the router, shut down all devices, reset the IP addresses on the receivers, deleted the wireless connection from the laptops, shut down the desktop, and just left the whole mess alone for half a day. Then I reinstalled the Norton Internet Security, connected my wired devices, plugged the modem in, plugged the router in, reset my security, connected wirelessly with my laptops.
Within an hour my connection timed out.
Trying to chat with tech support wasn't feasible, as my connection kept going out. A guy at work said I shoudl ping my IP address, and let it repeat until my connection goes out. So I unplugged the router and plugged it back in to get an internet connection, the opened a cmd prompt and typed
ping 192.168.1.1 -t
I left it alone for a few hours, and when I came back, my internet connection was down, but I was still getting active pings - no problems there.
At this point I thought I had done everything except replacing my router (which I'm still tempted to do), but I called my broadband provider to see if there was anything they could do. One of the techs said I had too many devices connected to the internet, but I thought these routers were supposed to handle dozens of devices?
I finally called Linksys Tech Support and had a conversation for 90 minutes. We went through all the steps of unplugging the the modem, router & all connected devices, resetting the router, etc, etc. The only thing different he did was had me change my security from WPA to 64-bit WEP, and added passwords for DNA1 and DNS 2 (same password for each).
That was at 1:30am last night, and when I woke up to check my connection this morning, it was still connected. I have to check it again when I get home, but I'm wondering if I should just be prepared to get another router (and if so, any recommendations), or if there's something I'm still not doing that could resolve my issue - if I still have connection losses.
Also, I'm concerned about the security thing. If changing from WEP 128 or WPA to WEP 64 fixed my problem, I'm not sure I feel completely protected from intrusion - isn't that pretty much the least amount of security I can have (without forgoing it altogether)??
Finally, I've read a few threads suggesting possibly changing to static IP from DHCP; however, my satellite receiver installation documentation specifically advises against this for the receivers.
Anyway, I would very much appreciate some help.

TOO many OPEN CURSORS during loop of INSERT's
Running ODP.NET beta2 (can't move up yet but will do that soon)
I don't think it is related with ODP itself but probably on how .Net works with cursors. We have a for/next loop that executes INSERT INTO xxx VALUES (:a,:b,:c)
statements. Apparently, when monitoring v$sysstat (current open cursors) we see these raising with 1 INSERT = 1 cursor. If subsequently we try to perform another action, we get max cursors exceeded. We allready set open_cursor = 1000, but the number of inserts can be very high. Is there a way to release these cursors (already wrote oDataAdaptor.dispose, oCmd.dispose but this does not help.
Is it normal that each INSERT has it's own cursor ? they all have the same hashvalue in v$open_cursor. They seem to be released after a while, especially when moving to another asp.net page, but it's not clear when that happens and if it is possible to force the release of the (implicit?) cursors faster.
Below is a snippet of the code, I unrolled a couple of function-calls into the code so this is just an example, not sure it will run without errors like this, but the idea should be clear (the code looks rather complex for what it does but the unrolled functions make the code more generic and we have a database-independend datalayer):
Try
' Set the Base Delete statement
lBaseSql = _
"INSERT INTO atable(col1,col2,col3) " & _
"VALUES(:col1,:col2,:col3)"
' Initialize a transaction
lTransaction = oConnection.BeginTransaction()
' Create the parameter collection, containing for each
' row in the list the arguments
For Each lDataRow In aList.Rows
lOracleParamters = New OracleParameterCollection()
lOracleParameter = New OracleParameter("luserid", OracleDbType.Varchar2,
_ CType(aCol1, Object))
lOracleParamters.Add(lOracleParameter)
lOracleParameter = New OracleParameter("part_no", OracleDbType.Varchar2, _
CType(lDataRow.Item("col2"), Object))
lOracleParamters.Add(lOracleParameter)
lOracleParameter = New OracleParameter("revision", OracleDbType.Int32, _
CType(lDataRow.Item("col3"), Object))
lOracleParamters.Add(lOracleParameter)
' Execute the Statement;
' If the execution fails because the row already exists,
' then the insert should be considered as succesfull.
Try
Dim aCommand As New OracleCommand()
Dim retval As Integer
'associate the aConnection with the aCommand
aCommand.Connection = oConnection
'set the aCommand text (stored procedure name or SQL statement)
aCommand.CommandText = lBaseSQL
'set the aCommand type
aCommand.CommandType = CommandType.Text
'attach the aCommand parameters if they are provided
If Not (lOracleParameters Is Nothing) Then
Dim lParameter As OracleParameter
For Each lParameter In lOracleParameters
'check for derived output value with no value assigned
If lParameter.Direction = ParameterDirection.InputOutput _
And lParameter.Value Is Nothing Then
lParameter.Value = Nothing
End If
aCommand.Parameters.Add(lParameter)
Next lParameter
End If
Return
' finally, execute the aCommand.
retval = cmd.ExecuteNonQuery()
' detach the OracleParameters from the aCommand object,
' so they can be used again
cmd.Parameters.Clear()
Catch ex As Exception
Dim lErrorMsg As String
lErrorMsg = ex.ToString
If Not lTransaction Is Nothing Then
lTransaction.Rollback()
End If
End Try
Next
lTransaction.Commit()
Catch ex As Exception
lTransaction.Rollback()
Throw New DLDataException(aConnection, ex)
End TryI have run into this problem as well. To my mind
Phillip's solution will work but seems completey unnecessary. This is work the provider itself should be managing.
I've done extensive testing with both ODP and OracleClient. Here is one of the scenarios: In a tight loop of 10,000 records, each of which is either going to be inserted or updated via a stored procedure call, the ODP provider throws the "too many cursor errors at around the 800th iteration. With over 300 cursors being open. The exact same code with OracleClient as the provider never throws an error and opens up 40+ cursors during execution.
The applicaation I have updates a Oracle8i database from a DB2 database. There are over 30 tables being updated in near real time. Reusing the command object is not an option and adding all the code Phillip did for each call seems highly unnecessary. I say Oracle needs to fix this problem. As much as I hate to say it the microsoft provider seems superior at this point. -
Can I connect a USB 2 sound card to a Macbook equipped only with USB 3 ports?
Hello,
I just learned I might have to purchase a new Macbook because my USB ports are fried and I was looking at purchasing a refurbished Macbook pro from 2012:
http://store.apple.com/ca/product/FD101LL/A/refurbished-133-inch-macBook-pro-25g hz-dual-core-intel-i5
the only trouble is I make music with a MOTU Audio Express sound card, and it only has a USB 2 port and a bus-powered Firewire (which I don't like using since it hasn't been too reliable in the past).
http://www.motu.com/products/motuaudio/audio-express/summary.html
Unfortunately, it seems that the Macbook I'm looking into purchasing only has USB 3 ports, and I looked for info on USB 3->USB 2 adapters online and this simply doesn't seem to exist. The only info I managed to find on this subject was this little bit on the Apple website:
Can a USB 2 cable be used to connect a USB 3 device to my computer?
If the device end of the cable fits into the connector on the device, yes. However, because it has fewer wires, you won't get USB 3 speed and power may be limited to 500 mA.
does this mean that I can connect a USB 2 cable from the USB 2 port of the MOTU sound card to the USB 3 port on the Macbook? I'm OK with the power and the speed being limited to USB 2 power, I just want to make sure I can actually use my sound card with this new Macbook.
Thanks!I think I'm understanding this a bit more now.
Here is the cable that I use:
http://www.amazon.ca/USB-Cable-Type-Male-Black/dp/B00183I7EE
The Type A part is the one that I'm currently putting into the Macbook and the Type B part goes in the sound card.
Would this work with a USB 3.0 port on the Macbook?
Thanks for your time and patience... -
Is it possible to have too many keyframes in one project in Premiere?
Hi all,
I'm using Premiere 6 on a Windows 7 ULT machine.
Is it possible to have too many keyframes in one project in Premiere?
I'm getting app crashes when I try to re-open a certain project in Premiere 6 and it seems that if that file has over 93 keyframes, then it will not re-open. But I can re-open that exact same project file with 93 keyframes in it, no problem.
But if I go any further and create any more keyframes than 93 in a new re-saved version of the exact same file, then that file will not re-open and I get an app crash... you can see screenshots of the two Windows app crash info panels below that I'm getting from three different bad Premiere project files that I've created so far.
I've tested and tested what is going on here and this seems to be what is causing the bad files. I've re-created the scenario and re-created files with over 93 keyframes from the same base project file that will still open... as soon as I get more than 93 keyframes in this file, then that newly saved file will not re-open after I close and try to re-open it.
This is 75 keyframes in one still image clip, 14 keyframes in another still image clip and 2 keyframes each in two other still image clips in a single project file... that is the limit... if I create any more keyframes in the clip that has 75 keyframes, the new file will save and render, but it won't re-open once it has been closed.
The two slightly different app crash info panels show, in the first one below,
"Fault Module Name: StackHash_e98d"
... and the second one shows,
"Fault Module Name: PREMINFO.dll"
... both messages with a little more different info in each one. I get either of the two error info panels when trying to re-open all three bad files that I've created with over 93 keyframes in them. That is, two of the files alternate between giveing "StackHash_e98d" and "PREMINFO.dll" when trying to open them and one of them always shows the "Fault Module Name: PREMINFO.dll" error.
So even the error messages are inconsistent with two of the bad files.
I've searched the internet for this error in association with Premiere and I've also searched on this forum and found nothing. Can anyone shed any light on this?
Thanks,
digiBill,
Even though I figured out a work around, I was still interested to know if these file opening crashes are related to Virtual Memory.
So on the topic of Virtual Memory... a few months ago I was troubleshooting a different problem in Premeire and I found this information...
"To improve performance in Premiere Pro, adjust the size of the paging file to a maximum of twice the amount of installed RAM."
Previous to that time three months ago or so, I had my Virtual Memory settings at the default automatic setting, but I tried setting my VM to twice the amount of installed RAM, and I've had it set that way ever since, just to make sure I'm optimizing the VM performance for Premiere and other apps.
But that isn't making any difference in this case. Today I also found information in a search that says to troubleshoot StackHash crashes, one should turn off "DEP" in the system settings for the application with the crash problem... according to the paragraph below, from the second post down by Chris on this tdistler.com page... http://tdistler.com/2009/04/10/stackhash-and-application-crashes-on-windows
Even though this was written in 2009 with Windows Vista in mind, many things for Vista work in Windows 7... it says,
"Here’s how 99 percent of Vista users can fix a StackHash failure. I’ll walk you through it step by step:
Method A:
1. Open your Start menu and click Control Panel
2. Browse to “System Maintenance” then “System”
3. In the left panel, select “Advanced System Settings” from the available links
4. You should now see the System Properties Window, which will have three sections. The top section is labeled “Performance” and has a “Settings” button. Click this button.
5. Select the “Data Execution Prevention” tab.
6. Select the option which reads “Turn on DEP for all programs and services except those I select”
7. Use the “Browse” button to locate the executable file for the application you were trying to start when you received the StackHash error, and click Open to add it to your exceptions list.
8. Click Apply or OK to commit your changes."
But I tried this and none of the three problem files that I encountered would open... I still got the StackHash_e98d or PREMINFO.dll crash errors.
So anyway, I'm a ways past that in my project now, just continuing with more keyframes over the number of 78 in separate but identical still image clips... that allows me to successfully work with this project with as many keyframes as I need.
Thanks again,
digi
