How to support multiple users at the same time?

Hi all,
I have a Labview software which controls a analyzer via GPIB connector. When user A is using the software, user B has to wait until A is done. But actually, the analyzer is not very busy, when user A is using the software.
I want user A, B, C and D can use the software at the same time. just like we can open Multiple websites at the same time.
How can I program the software, so that the software can be open multiple times? Do you have any example?
Thanks a lot.
Steven

Are all the users going to be measuring the exact same thing from the same instrument?
It would be possible to write a separate instrument server application that would handle all the direct interactions with the instrument. When one of the users needed to access the instrument, they would gain access to it through this server.
The big, Big, BIG caveat is that each interaction with the instrument would need to be atomic. In other words each access would need to configure the instrument, initiate the reading, report the results, and then reset the instrument back to some known default value.
As Dennis said, not a trivial process, but probably do-able...

How to Modify multiple users at the same time.

Hi All,
I oversee a lab with 8 24" imacs running 10.4. Each machine has the same set of guest user accounts. The machines are not connected by a actual server, although I can dump files to a common folder. My problem is every time I want to make system pref changes I have to go into each user account to apply them, (i.e.,adding a new monitor profile). Any ideas or work-arounds out there?
Thanks
Phil

Hi Phil, and a warm welcome to the forums!
It's not clear if these are connected in anyway, but if they are, something like Timbuktu® Pro for Mac OS X, or ARD...

How to display multiple reports at the same time

Hi,
I'm trying to display multiple reports at the same time, each one in separates tabs or windows using Forms 11g 11.1.1.6
I have a button which has a call to a procedure which makes use of rp2rro library to show the specific reports, for example:
call_report('report1');
call_report('report2');
call_report('report3');
call_report('report4');
The main problem is that, just the last report is been displayed.
Is there some way to display report1, report2 etc in separate tabs or windows ??
Regards
Carlos

You shouldn't have a problem calling different reports at once. As long as you're using Forms 11g they show up in different windows.
The question is how you are calling the report.
Here is how I manipulate it.
After I pass parameters with the ADD_PARAMETER built-in I set some key values (destype, desformat, desname) with the RP2RRO's procedures.
Finally calling RP2RRO.RP2RRO_RUN_PRODUCT and then WEB.SHOW_DOCUMENT passing the correct procedure parameters the report comes up in a window. If you repeat the above changing the appropriate variables (the report_name in the RP2RRO_RUN_PRODUCT and so on) you can get multiple reports in different windows.

In OEM 12c, how to manage multiple incidents at the same time?

Hi,
Is there a way to manage multiple incidents at the same time? For example, if I want to assign owner for multiple incidents in the incident manager, is there a way to do this? Thanks for the help.

This is currently not supported. This support will be available as part of the next patch set release.
Please note that you can use Incident rules to assign owners to incidents as they come in or get updated.

Import PST files for multiple users at the same time?

While importing PST files into archive mailboxes, the Exchange 2010 mailbox server went to 100% CPU and memory usage and I could not stop the imports because the EMS stopped responding. We had to restart the whole server to get back to normal.
Not sure if importing PSTs was the cause of it it was a coincidence. We have done imports the same way before without this issue.
How many PST imports can be done at the same time and how do we queue up multiple users and have the mailbox imports have unique names for each user? I noticed they are always called MailboxImport and MailboxImport1 and then it starts over as MailboxImport
again for additional users. So, if more than one user's PSTs are being imported at the same time, we will have multiple identically named imports running.
We would like multiple users' PST imports to queue up and start automatically when the previous users' imports complete.

Please try like this. Rename folder name same as alias. i.e. \\server\share\<alias>. below are examples.
"\\server\share\jsmith"
"\\server\share\tjones"
"\\server\share\rsmith"
"\\server\share\bspears"
"\\server\share\mmouse"
And run below command to take PST from the corresponding
foreach ($i in (Get-Mailbox)) { New-MailboxImportRequest -Mailbox $i -FilePath "\\Server\share\$($i.Alias)\$($i.Alias).pst" -baditemlimit 50 -acceptlargedataloss ;while ((Get-MailboxImportRequest -mailbox $i | ? {$_.Status -eq "Queued" -or $_.Status -eq "InProgress"})) { sleep 180 } }
If a folder missing with the alias you will see an error similar to this.I think this will work for you. You just keep only the required PST folders to import in the "\\Server\share" folder.
"Unable to open PST file '\\server\share\mmouse\mmouse.pst'.
Error details: Could
not find a part of the path '\\server\share\mmouse\mmouse.pst'.
+ CategoryInfo : NotSpecified: (0:Int32) [New-MailboxImportRequest], RemotePermanentException
+ FullyQualifiedErrorId : 27802833,Microsoft.Exchange.Management.RecipientTasks.NewMailboxImportRequest"

Updating single row by multiple users at the same time

Hi,
I have been asked to develop an application where a single row from a table will be accessed by multiple users. Even multiple users can try to update the same row at the same time. So, to provide a solution of this problem should it be the best way to lock that particular row when user requesting to update it and after completion of commit the lock will be released. In the same time if some other user request to update the same row then it will be in the wait condition.
Please provide suggestion that is it the best way to handle the situation or not. If it is then can you also please provide an example (with sample code) of it.
Regards,
Koushik

It depends entirely on how the system was built.
You could relatively easily build an application that does something like
- Select a row with as last_updated_date column
- Update the row specifying the last_updated_date you had selected in your WHERE clause
- If the update updates 1 row, it was successful, otherwise inform the user that the row was already updated.
In this case, the second user would get an error indicating that the seat had already been purchased.
You could also relatively easily do a SELECT FOR UPDATE to prevent users from ever getting an error between the time they select a seat and the time they finish their transaction. Of course, if the user wanders away from the computer, or inadvertently ends up locking dozens of rows, this tends to rather problematic in practice. You may find that when the train pulls out of the station, someone that never ended up buying a ticket has locked a dozen rows so you lost a dozen sales. If you have a call center where operators are reserving seats for people on the phone, you may decide that explicit locking is more appropriate because you're confident that the operators aren't going to leave tickets locked for long periods of time and the cost of having the customer walked through the seat selection process multiple times would be higher than the cost of having rows locked longer than they need to be.

How to use multiple languages at the same time for spell checking?

I use two different languages all the time and words are mostly so different (English and Finnish) that I could have spell checking on for both languages at the same time.
Now it seem to allow to select only one language at the time and I have to switch back and fort zillion of times per day.

Thanks for the quick answer.
The Dictionary Switcher doesn't seem to work with Finnish language, it doesn't detect it at all to be one of the choices although in the Firefox context menu Languages -> Finnish/Finland is shown.
Also, if it would work, I would need to get rid of multiple EN_* langauges. I just need EN_UK or EN_US, not all 22 different EN_*.
One option would be to create a custom dictionary, which would have words from both languages. The next task is then to find out how to make this kind of custom ENFI-dictionary, which would have words from both English and Finnish languages.
Finnish may be a some kind of special case for spell checking anyway, because the support is in its separate plugin:

Outlook autocomplete cache stops working for multiple users at the same time

Hi there
Ever since we upgraded our Exchange 2010 to Exchange 2013 we have had problems with the autocomplete cache in Outlook 2010.
We have 700 users and about once per week I get a call about the autocomplete cache. A few users are on cached mode, but most use online mode. The problem appears on both, but it can usually be corrected by /cleanautocompletecache.
Granted, the autocomplete cache gets corrupted sometimes, but it seems to happen a lot for us. I have noticed that often more than one user experiences the problem at the same time, and, since the problem starting after upgrading Exchange, I suspect that
the issue is with Exchange and not Outlook. Yesterday three users complained about the cache at the same time.
I know how to get a broken cache going again - that is not the issue. The issue is keeping this from happening so often.
Anyone out there able to help?
Thanks!
/Anders

Hi ,
Based on my knowledge , when you tried to send an email to a recipient in the same exchange organisation then the recipient address will be resolved in to legacy dn value and then that email will be delivered to destination mailbox by pointing towards to
that legacy dn value.
For the external recipients exchange user the smtp address to get it delivered.
For your issue :
Based upon the NDR message , we need to covert those values in to x500 format and add it to respective recipient mailbox as an x500 address.Then These erorrs will happen if the x500 value of the destination recipient is not available on it's maibox
and that would be the cause of the NDR for most of the times.Some time as you said autocomplete cache would get corrupted on the client end but it is very rare.
How to convert NDR to x500 address format :
http://msexchangeguru.com/2012/03/15/x500/
How to avoid getting such kind of NDR'S :
https://www.simple-talk.com/sysadmin/exchange/exchange-e-mail-addresses-and-the-outlook-address-cache/
In case if you don't want the users to use the autocomplete cache when composing the new emails :
In group policy we can use the office templates to disable the below mentioned option.
1.use autocomplete to suggest the names ---> this option will comes under the advanced settings on the outlook client.
In case if you don't want the users to use the autocomplete cache when composing the new emails as well as if you wanted to delete that autocomplete then you need to choose one more option along with the first one.
1.Empty autocomplete cache.
Please reply me if anyhitng is unclear.
Thanks & Regards S.Nithyanandham

How top open multiple forms at the same time in HRMS menu

Hi,
When enabling "Close Other forms" in HRMS menu by excluding the function ‘Navigator: Disable Multiform’ Function in the Responsibility Definition (System Administrator -> Security -> Responsibility -> Define), mutliple forms works fine but I'am facing another error.
My problem is: when this option is enabled, I tried to run Payroll run request but it turned out that payroll list of values is returning empty values and I'am unable to select any payroll from list of values. the only way to do so is to remove back ‘Navigator: Disable Multiform’ Function from exclusion section in responsibility.
My requirment is: to have multiple form and payroll run list of values working at the same time
Thanks

Reason for this , if ur request is attached to more than 1 responsibility , i think this issue will come , we got same issue
we remove it from responsibility list , then it is working fine

How to open multiple applications at the same time

I need to open several applications at the same time: Dreamweaver, BBEdit, and Acrobat. Is there a way to smooth this process, so pressing an icon in the dock will open them all for me?

You could create an applescript to do it.
tell application "Dreamweaver's Full Name"
activate
end tell
tell application "BBEdit's Full Name"
activate
end tell
tell application "Acrobat's Full Name"
activate
end tell
Replace the quoted text (leaving the quotes) with the full name of the application, and save the applescript as an application bundle, and put it in your dock.
NOTE: You may have to put the full path to the application for it to work (I.E. /Applications/Dreamweaver.app). If you do, encase the full path in quotes.
Good luck!

Can I assign a Manager to a group, or to multiple users at the same time?

Our company uses Connect to manage internal training. At the moment, if a Manager moves on, I have to manually change the assigned Manager of each user, one at a time.
Trouble is that I am responsible for over 5000 users and each Manager is responsible for over 100 users, which makes this task a lengthy one.

Hello B,
Are you acquiring with all 8 channels? If not, you can use one of your unused channels as an analog trigger source, and input your digital trigger there.
Alternatively, the PCI-5105 has a RTSI connector on the rear of the board. This connector gives you access to 8 digital RTSI lines which can be used for digital triggering. See the following KB for more information about RTSI:
http://ae.natinst.com/operations/ae/public.nsf/web/searchinternal/ad2d553f55a07bbf8625650d005f1f00?O...
You are correct. You can fetch data while an acquisition is in progress. And you can fetch more data than will fit into memory provided you set the Enable Records > Memory property to true. Take a look at the "niScope EX Fetch In Chunks.vi" and "niScope EX Multi Record Fetch More Than Available Memory.vi" shipping examples in:
C:\Program Files\National Instruments\LabVIEW 8.2\examples\instr\niScope
I hope this helps.

Can an Apple TV support multiple PC at the same time?

My boss and I were wondering if an Apple TV could help us in a specific situation.
Let's say we are having a meeting and we are 3 in the room. Alternatively, each of us will have to present some slides / share our PC Screen. Today, we have to unplug the VGA/HDMI cable, and pass it to the other. This is non value added.
The 3 of us are running Dell PC's with Windows 7 & XP, and we were wondering if we had an Apple TV device, could the 3 us be able to share/mirror our screen, and (with the remote or and app), switch from one screen to the other ?

Hi
So basically, we get the Apple TV2, connect it to our Flat Screen, then we would have to install "Airparrot" on all PC that would need to mirror its screen on the Flat Screen.
As for connecting and disconnecting, how does this work? Every PC is having like a"control" panel where you can disconnect/connect or you do this using the remote?
About if Xbox allows this, I'm not aware, but not sure who we could "justifying" getting an Xbox for the office, where as an AppleTV would make more sense
Thanks
