Bulean switch for DO trigger

Hello everybody,
I am kind of puzzled regarding the problem I encountered in my vi. It does forces aquisition from a load cell and it records motion coordinates from my motion system.
I added a block for DO trigger, that sends TTL 5V signal to a PIV system, trigger does work, and I can read signal on both multimeter and PIV starts its sequence after it. What I am tryint to accomplish is to start recording to file and triggering at the same time.
I tried to wire bulean switch from my "write to file" control to digital bool <<data>> slot, but when I run vi, as soon as I push "record", labview freezes. If I create a dedicated bulean control for the trigger(which is what I have in attached file), everything works fine.
Can somebody sugges a possible solution?
Thanks in advance
Oleks

Oh, yeah, I should pay more attention to spelling
I'll update vi tomorrow, as I don't have access to Labview at home, but yes, record will be "write to file" switch that is wired to two "write to file" subVIs.
Basically I tried to wire it also to DO switch in order to achieve synchronous recording/triggering. Anyways, I'll update post tomorrow with appropriate file.
Thanks for the response Ravens!

Remote deployment switches for Jabber 9.2.2

Are there any installation switches for remote install via the MSI/DMG?
I will be pushing this backage via Dell KACE K1000 appliance and would like to configure default options for the users during the install/upgrade such as Disabling (or 'unchecked' following initial sign-on) the Docked Window, configuring Phone Accounts, WebEx Meeting and application Integration settings.

application integrations setting mostly get pushed out through the profiles on CUPS that get pushed out as soon as the user logs in.
I can't help you out with all the switches you asked for but, you can starting using:
msiexec.exe /i "\\lsrftufs1\ict\Networks\Voice\Jabber\Jabber 9.2.2\CiscoJabberSetup.msi" TYPE=CUP DOMAIN=somedomain.com.au LANGUAGE=1033
This will at least use auto discovery of the presence server if you use an SRV record _cup._login.somedomain.com.au
so at least your useers wont have to type in a presence server name or IP.

Time Capsule - Can it run as DHCP router, create a wireless network and plug into switch for wired network all at the same time?

I have a closet with Wired connections from all over the house terminating in it. I also have the internet modem and a switch in this closet. My old setup was a netgear in the closet creating a wireless network and also feeding the Ethernet ports all over the house. In my room, I had an Airport express (a month old) bridging the wifi to make the wifi network larger. The Express was hard wired from the wall and my mac mini was using it's wifi (printer was plugged into other ethernet port). Everything was working great.
Fast forward to last week. My Netgear died. So, I bought a time capsule. My plan was to move the Express to the closet and have it create the wifi network and also then run cat 5 cord from express to the switch to feed all the wired wall plugs. Reset it and set it up to create the wifi network as well as DCHP NAT. Wireless was running great on it. Then I plugged in the Cat 5 in the second Ethernet Port to the switch. Wifi stopped working and none of the computers would connect using wired connections either. They would see a 'network' but nothing would work. I would unplug the Cat 5 feeding the swtich and the wireless would start working again. Plug the Cat 5 back in and wireless would stop.
So I thought I would try the Time Capsule in the closet and see if I could get it to work. Pretty much the same thing, except at this point I figured out if I went in and told it NOT to create a wifi network the wired portion worked fine and all the wired computers in the house worked fine. Of course, then I didn't have Wifi.
I'm not clueless when it comes to networking, but I can NOT figure this out! Can either the Time Capsule or Express Create the wifi network AND also feed the data to the switch for all the wired computers?
To simplify this is what I want my end result to be. I prefer the Time Capsule to be the wireless connection extender, but if I have to have the Express do it, I'm fine with that.
1. Express in the closet creating the wifi network as well as feeding the data to the wired connections via my switch.
2. have the Time capsule in my room at the opposite end of the house plugged into the hard wired connection to extend the wrieless network as well as have wired connections such as my printer and my Mac Mini.
If I can get #1 to work, I don't think I'll have any problems with #2. Help!

I have an equally complex setup with a managed switch actually but I have never seen the TC have this kind of issue.
What I do notice is you have changed the TC from defaults.. you are using a non-default IP range.
I have run across issues like this where people move things from default.
I would like you to start over.. factory reset the TC. That will set it back to default router mode.
Do the min setup on the TC..
1. Change all names from what you were using. That includes the TC name and wireless name/s
Make them short, no spaces and pure alphanumeric because that is the correct way to network. Apple default names with spaces and apostrophes are fundamentally bad.
2. With just the TC plugged into the switch.. and a single computer connected by ethernet. Power cycle the whole network.. this allows the switch to clear all the old MAC address.
3. Test on the computer just ethernet. Turn the wireless off.
The computer must use dhcp and must get an ip from the TC.
It has to get the correct Router.. ie Gateway.. I wish apple could stick with proper network terminology.
And it must get same address or valid DNS server address/es.
If it fails.. please plug ethernet directly to the TC.. bypassing the switch.
You should get the standard IP addressing and internet connection.
If not please post the screenshot from the Mac of the network preferences showing the ethernet setup.
I need to see what address it does get. I need you to make sure the ethernet is the TOP of the list. So rearrange the order of network connection. With the airport off it should just go to the top of the list.
If it appears to be working .. but a browser cannot connect, open a terminal and ping an internet address.
Ping the actual gateway address the ISP gives you and ping the ISP dns address.

How to take a single data point for each trigger pulse ( synchronous acquisition).

hi
          im using the pci-mio-16E1 card, with the IDE VC++, so im looking for an example to explicate me how to make an synchronous acquisition data using an external timing, so the idea is to acquire (take) a single data point for each trigger pulse from one input channel ,and saving the data in a file .
now im making a code using the AI_setup and DAQ_op functions, im getting a speed acquisition (it is the start of acquisition data), and it is a synchronous acquisition just for one trigger pulse, and me i looking for an acquisition for each trigger pulse.
so to  understand my problem you can see my code :
iStatus = Timeout_Config(iDevice, lTimeout);
         iRetVal = NIDAQErrorHandler(iStatus, "Timeout_Config", iIgnoreWarning);
   // configuration and selection of signal trigger
         iStatus = Configure_HW_Analog_Trigger(iDevice, ND_ON, iLowValue,iHighValue, ND_ABOVE_HIGH_LEVEL, ND_THE_AI_CHANNEL);
        iRetVal = NIDAQErrorHandler(iStatus, "Configure_HW_Analog_Trigger", iIgnoreWarning);
iStatus = Select_Signal(iDevice, ND_IN_CONVERT, ND_PFI_2,ND_HIGH_TO_LOW);
         iRetVal = NIDAQErrorHandler(iStatus, "Select_Signal", iIgnoreWarning);
    iStatus = AI_Setup(iDevice, iChannel, iGain);
   iRetVal = NIDAQErrorHandler(iStatus, "AI_Setup", iIgnoreWarning);
   while ((iReadingAvail != 1) && (iStatus == 0)) {
/* Wait until reading is available. */
         iStatus = AI_Check(iDevice, &iReadingAvail, &iReading);
        iRetVal = NIDAQYield(iYieldON);
       // Acquire data from a single channel
    iStatus = DAQ_Op (iDevice, iChannel, iGain, piBuffer, ulCount, dSampRate);
   while ((iDAQstopped != 1) && (iStatus == 0)) {
        iStatus = DAQ_Check(iDevice, &iDAQstopped, &ulRetrieved);
        iRetVal = NIDAQYield(iYieldON);
       iStatus = DAQ_VScale(iDevice, iChannel, iGain, dGainAdjust, dOffset,ulCount, piBuffer, pdVoltBuffer);
      iRetVal = NIDAQErrorHandler(iStatus, "DAQ_VScale",iIgnoreWarning);
   /* Set analog trigger mode back to initial state. */
       iStatus = Configure_HW_Analog_Trigger(iDevice, ND_OFF, iLowValue,iHighValue, ND_ABOVE_HIGH_LEVEL, ND_THE_AI_CHANNEL);
/* Set PFI line back to initial state. */
       iStatus = Select_Signal(iDevice, ND_IN_START_TRIGGER,ND_AUTOMATIC, ND_DONT_CARE);
          iStatus = DAQ_Clear(iDevice);
/* Plot acquired data */
      iRetVal = NIDAQPlotWaveform(pdVoltBuffer,ulCount, WFM_DATA_F64);
so this is the data acquired -0.900879,-0.900879,-0.900879,-0.900879,-0.900879,-0.900879,-0.900879,-0.900879 and i think that is a noise because all time i get this data.

Locked button & switch for volume is broke also back is cracked , can i get my phone replaced for free ?

my lock button and the switch to turn the volume on & off is broke. also the back of my phone is cracked. i know apple doesn't replace cracked phones so would i have to pay for a replacement even though my lock button & the switch for the volume is broke ? if so , how much ? or would if be cheaper to just but a whole new iPhone ?

If your damage is caused by accidental damage or intentional user damage, then you would be looking at an out of warranty repair. I'm not sure what the costs of an out of warranty repair are for an iPhone 4, but they are probably in the $99-149 USD range.
The cost for getting a new iPhone would depend upon your current contract status. If you are out of contract, you can get a new iPhone 4s (the next newer model) for free.

Dynamic Environment Switching For REPORTS_PATH 11g

Oracle Fusion Middleware 11.1.1.2.0 with Patch Set 2 (11.1.1.3.0) - Linux
Dynamic Environment Switching For REPORTS_PATH doesn't work.
According to documentation B32121-03 (Publishing Reports to the Web with Oracle Reports Services 11g Release 1 (11.1.1) point 8.2.2):
1. comment REPORTS_PATH in reports.sh
2. set enviroment settings in rwserver.conf with REPORTS_PATH and NLS_LANG and defaultEnvId (DEV and PRD with defaultEnvId="DEV")
3. restart reports server
4. run http://mywls:8888/reports/rwservlet?SERVER=rep_wls_reports_mywls_asinst_1&REPORT=testreport.rdf&USERID=user/user1@mydb&DESFORMAT=html&DESTYPE=cache&ENVID=DEV
REP-110: File testreport.rdf cannot be opened.
REP-1070: An error occurred while opening or saving a document.
REP-0110: File testreport.rdf cannot be opened.
The same situation for &ENVID=PRD or without ENVID (as I expect it should work as default - DEV enviroment). File testreport.rdf is located in both paths (/u00/DEV/reports and /u00/PRD/reports)
http://mywls:8888/reports/rwservlet/showenv?server=rep_wls_reports_mywls_asinst_1&authid=oiduser/oiduser1 reads informations from reports.sh file but doesn't read enviroment settings from rwserver.conf (REPORTS_PATH is empty because I comment it in reports.sh).
Where's my problem? Should I set any other setting(s)?
Unfortunately note [231051.1] and other referenced doesn't resolve my problem...
Edited by: user9093781 on 2011-08-23 06:50

Not sure if this helps at all. I just went through a nightmare trying to get 11g forms/reports to work through the forms builder.
What I discovered with that is that I indeed had to set the REPORTS_PATH in rwserver.conf... however there were 3 different files that I ended up having to put it in (not sure if had to be in all 3). And perhaps more importantly, there seems to be an order to how you put these xml statements in the rwserver.conf files.
In my case, it wouldn't work at all until I put it right after the last "<engine id=" statement.
Mine looks something like this (not that this is a snippet of the file in Windows, for running via Forms/Reports Builder):
<engine id="rwURLEng" class="oracle.reports.urlengine.URLEngineImpl" maxEngine="1" minEngine="0" engLife="50"/>
<environment id="default">
     <envVariable value="C:\Oracle\WLS11gR1U4\user_projects\domains\AISworkstation\" name="REPORTS_PATH"/>
     <envVariable value="AMERICAN_AMERICA.WE8ISO8859P1" name="NLS_LANG"/>
     <envVariable value="RRRR-MM-DD" name="NLS_DATE_FORMAT"/>
</environment>
<environment id="windev_xxxxxxxx">
<envVariable name="REPORTS_PATH"
value="M:\ADS\Dvlprs\xxxxxxx\11g\FormsApps\stage;M:\ADS\Dvlprs\xxxxxxx\11g\FormsApps"/>
</environment>
I'm still figuring this all out too (although I did get it working how I need.. just not sure if it is the optimal solution), so I'm not sure how much this will help you. But for sure I can say that there is an order to these XML tags that I'm not so sure was the same (or maybe not enforced) in 10g.
Good luck

Silent Uninstall Switch for FlashUtil32_11_4_402_278_ActiveX.exe

I know I can run 'FlashUtil32_11_4_402_278_ActiveX.exe' (found in 'C:\Windows\System32\Macromed\Flash') manually, but I'd like to automate the removal process to avoid having the user click on anything. (I want zero user interaction!)
Are there any silent/unattended switches for FlashUtil32?

Hi Pat & thank you kindly for at least responding to the thread. I greatly appreciate it.
For what its worth the -uninstall switch works for the following executables in C:\Windows\System32\Macromed\Flash:
FlashPlayerPlugin_11_XXX.exe
FlashPlayerUpdateService.exe
FlashUtil32_11_XXX_Plugin.exe
It does not seem to work for the FlashUtil32_11_XXX_ActiveX.exe. However, as you pointed out, it does work with the uninstall_flash_player.exe, and that seems to get rid of the last remaining FlashUtil32_11_XXX_ActiveX.exe file (among other things I'm sure).
Thanks!

Switch for showing my telephonenumber locked

The switch for showing my number is locked. My iPhone shows unknown number when I call someone. I think it has something to do with my iCloud account. I tried to put my SIM card into another iPhone and my number showed. So I got a new iPhone and downloaded my iCloud profile to the new iPhone and the same problem was back. I started this iCloud profile with a 3s iPhone with a diffrent telephone company and a diffrent telephone number. Any thoughts?

The carrier I'm using is connected to my office and several of my colleagues uses iCloud and doesn't have this problem.
I have my old mobile number divert to this number I'm using now. Can that cause this problem?

Switch for Distribution Layer

I need your expert opinions for selecting a switch for distribution Layer
My requirement is 24Gig ports @ dist layer which will connect to 3750?s for server farm. I don?t want to negotiate with the bandwidth.
Which switch will be best for this scenario with max Backplane speed

Yes L3 routing will there.
I am considering 3750 for access switch for my server farm, and 4506 for distribution layer with the following port requirement
Catalyst 4500 Gigabit Ethernet Module, 6-Ports (GBIC)
Catalyst 4500 GE Module, Server Switching 18-Ports (GBIC)
Catalyst 4500 Enhanced 48-Port 10/100/1000 Base-T (RJ-45)
Catalyst 4500 Supervisor IV (2 GE), Console (RJ-45)
Most of the gigabit port will be occupied since I have a huge server farm to connect. By using almost all the ports on 4506 will I be able to get the maximum through put??
I have not considered 6500 due to budget. If I consider 6500 will it be a good design to have 6500?s on both core and distribution layer

Switch for String

Hi,
I need to do a switch for a String and not an int.
ex:

You cannot. Java only lets you use switch on int or char.
Sorry, but only the if else will do here

If you use the organizer, you need to buy the boxed version of PSE 12. You can usually find it at big box stores and online retailers for less than adobe's upgrade price, if you shop around. You need the boxed version because you get a serial number that works on both platforms, and you will need to install PSE 12 in windows first, upgrade your catalog, then make a full backup to a removable drive and restore from that to the mac, after installing PSE 12 there.
If you don't use organizer, it doesn't matter.

Flash Media Player which handles bitrate switching for live streams?

Hello. I've got a very short timescale to find a solution for a way to display livestreams with bitrate switching. Does anyone
know of any opensource players which can do this effectively? Or do the inbuilt components in CS4 deal with this ok?

Thanks,I have read that article. Based on that article the NetStreamInfo.maxBytesPerSecond is not an accurate measurement to base dynamic switching on. This seems to be the basis of the bitrate switching in both the longtail player, and the adobe examples that I have tried. That article suggests using the dropped frames property, in conjunciton with bufferlength to determine if switching is neccessary. Unfortunately I can't seem to find a player online which handles this successfully. That being said, I can't believe I'm the only person trying to implement dynamic bitrate switching for live streams so surely there are some players out there which can do this successfully? If anyone knows of any code available which does this successfully I would appreciate knowing where! The examples provided by Adobe https://www.adobe.com/cfusion/entitlement/index.cfm?e=fms35 unfortunately don't work either.

Using DAQ occurrence to wait for start trigger

Hi,
I'm trying to use digital triggers to start and stop datalogging. Every time start trigger appears, new file is created and data is acquired to file until stop trigger occurs. Now I'm using set DAQ occurrence and wait for occurrence functions to wait for start trigger before creating a new file. The problem is that after first stop trigger this occurrence method doesn't work. I believe it's because AI is not cleared and configured before calling DAQ occurrence again. Number of scans acquired is not zero, if I don't clear and configure AI again? Am I right?
Do I have to clear and init AI everytime before occurrence config or is there a better way to make program wait for start trigger?
Thanks in advance,
Jakke

Hi Matt99eo,
Have you configured your device for triggering? Although you have not mentioned your device specifically, the M series user manual provides a great explanation of digital triggering. Using the DAQ Assistant, this can be configured from the triggering tab. Hopefully this helps!

Is it possible to use the same Switch for two different clusters.

I have 10g Rac setup on windows.
Now I am planning to install 11gR2 on different servers.

Yes. Technically there will not be any conflict as long as the private addresses used by the 2 clusters do not collide, and provided that the switch's port capacity and bandwidth will not be exceeded.
Your NA (netadmin) can also configure the switch to separate the 2 Interconnects from one another (called partitioning when using Infiniband) - if the switch supports such features.
A major consideration is not to make the switch, public. That typically cause a range of problems and can have a serious impact on an Interconnect. But using 2 private networks on the same infrastructure should not have the same problems - if configured and implemented correctly.
