Wait for 3 minutes and then run another method

I'm calling a JMS service lets say runProgress() the method adds a new row into a database then waits for 3 minutes and then runs another method that removes the row from the table.
I was thinking about this, and thought that I could create a new Thread, let it wait for 3 minutes and the run the other method.
The thing is what happens if there are 10.000 users running this at the same time, then there would be 10.000 Threads, wouldn't it be a hevy load on the server.
Is there any other way?? Suggestions?

What do you think about if there are massive, like
10.000+, queue's in memory, this would be slow down
for the server, right? or isn't it a trouble?you don't need 10.000 queues - just one single queue. you may have a lot of objects in the queue but this is at most a memory problem - depends on the size of the information you need.
maybe i was not clear enough: you have a single queue where the tasks are put into. then there are other threads (at least 1) that read from the queue and perform actions.
One option, that I don't know how to do yet but
thinking about it, is to let the database have some
kind of a procedure that would run after 3 minutes,
but I guess that I were only moving the memory trouble
from the app-server to the database. (hope you
understand me)yes, i think so.
So it would be just as good to do this in the
app-server as in the database, what do you think?a good idea. typically with all these optimization issues you just have to try out. otherwise you won't know the result.

Hey guys my iphone 5 sync and at step 6, it say waiting for changes and then it cancel syncing.

You meant iTunes 11.1.2?
Try disable anti-virus and firewall and try again. You can switch back on after you've finished.

HT201407 iMessage "unable to activate, please try again". Whenever I go to activate imessage is says waiting for activation and then about 5 mins later says activation unsuccessful, please try again. This is driving me mad! It's been 2 days now!!

Lease help me to activate imessage. I now have iPhone 5s and can't activate imessage. I've tried all the normal stuff but nothing is working

i had this problem with my iphone 5c and sorted it contacting apple.
have you tried resetting the network settings? it doesnt delete anything and should work. if it then changes to "waiting for activation", instead of the error message, then leave it for 24 hours (leaving your phone and wifi on) and it should activate and work.
for me, this didnt work after 24 hours. i then backed up my phone and reset it and set it up as a new iphone then restored it using my backup from the computer and it now works

My PowerBook G4 says that it's connected to wifi, but it still no internet connection. The connection will work for a while, and then I'll have to run diagnostics and it will work again for a few minutes and then stop working again. What's going on??

I am using Iphone 5. Since the last 3 weeks the phones has been acting weird. on dialling a call it get hung on disconnecting it stays on the call ending screen only. this happens for atleast 5 to 7 minutes and then it gets to normal

I am using Iphone 5. SInce the last 3 weeks the phones has been acting weird. on dialling a call it get hung on disconnecting it stays on the call ending screen only. this happens for atleast 5 to 7 minutes and then it gets to normal or the other way is to turn the device off and then turn it on. the phones also running slow and therefore at times becomes very cumbersome. a few of my friends have also been having the same problems.
I have taken the phone to the service outles but the best they did was to reboot the phone it works fine for a day or two but again the same issue.
Can anyone share any info on it?

I'm glad to hear that they replaced your phone. Any experience I have had with Apple customer service and/or Genius bar has been extremely positive. While I have had positive outcomes from trouble with other phones in the past, they are not as quick and friendly. I had a Motorola phone and a Samsung phone go bad several years ago and warranty work through AT&T required that I wait for a replacement unit and then mail back the original unit to keep from being charged for the device. This usually meant almost a week without a phone. Nice to walk into Apple and walk out with a replacement device. Enjoy your phone.

HT3371 When I plug in the computer to charge, the light is green for a minute and then turns red and the plug gets very hot. It's not the plug as it works on other computer. Why won't my computer charge?

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged after the boot, during the time something abnormal was happening. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).
For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes after the boot time, not before. Please include the BOOT_TIME message at the beginning of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

I'm having the same problem. I'm using a new shuffle usb cable in my 2nd generation shuffle and nothing shows up on computer. I'm wondering if the dock for the second gen is different than the new usb cable direct into the 2nd gen shuffle. I don't have a dock for it. Before I buy one on ebay I hope someone can assist.

As long as you use your computer like King Penguin stated for Report a Problem, you should be fine. If you can't get to your computer, are not using your computer, or your computer is not longer in the mix since you have been using your iPad, email iTunes support about the problem.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
