Using SwingWorker more than five times

Hi there,
I'm having a problem with the SwingWorker.
A SwingWorker class is called for loading a large file into the database. After I have loaded five files to the database, the sixth loading isn't working and the GUI isn't responsing anymore. Is there a maximum number of SwingWorker Threads that can be used at a time?
Everything else works fine, and sometimes I can even load more than five files, if the loadings are long enough after each other.
Can anybody help?

dbHighly probably--about 5 orphaned connections seems to be where things have gone bonkers for me in various languages in the past--C, C++, VB, C#, Pascal, Basic... argh! The mind dizzies.

How to use between more than 3 times in a single query?

is there any other query to run this query??
SELECT IDSITE,IDVISIT,trim(initcap(page_path)),KEYWORDS,LOCATION_IP,REFERER_NAME,REFERER_URL,VISIT_ACTION_TIME,count(DISTINCT location_ip) from web_stats where idvisit between '441' and '456' and where idsite='1' and visit_action_time between '4-jun-11' and '6-jun-11' group by trim(initcap(page_path)) and order by visitid;

Too many WHERE's and too many AND's and dates being treated as strings, and not the right number of grouping columns...
Something like this is more likely to work.
SELECT IDSITE
      ,IDVISIT
      ,trim(initcap(page_path))
      ,KEYWORDS
      ,LOCATION_IP
      ,REFERER_NAME
      ,REFERER_URL
      ,VISIT_ACTION_TIME
      ,count(DISTINCT location_ip)
from   web_stats
where idvisit between '441' and '456'
and    idsite='1'
and    visit_action_time between to_date('04-jun-2011','DD-mon-YYYY') and to_date('06-jun-2011','DD-mon-YYYY')
group by IDSITE
        ,IDVISIT
        ,trim(initcap(page_path))
        ,KEYWORDS
        ,LOCATION_IP
        ,REFERER_NAME
        ,REFERER_URL
        ,VISIT_ACTION_TIME
order by visitid;Note: assuming visit_action_time is a DATE datatype, the comparison should be against DATE datatypes also, rather than strings, so you should use TO_DATE to conver those strings to dates. It's also good practice to use 4 digit years rather than 2 digit years, as we had to solve all the 2 digit year millenium bug issues back in the late 90's; we don't want to have to do that again now do we?

HT1420 Authorizing More than Five Computers

Why can't use authorize more than five computers? It is driving me crazy!

Because that is the limit that Apple have decided on, if you want to know why then you'll need to try asking them (and iPads, iPhones and iPods aren't included in the 5 computer limit).

Since I upgraded to Adobe Created Cloud, my photo editing processes are taking more than 10 times longer than they used to. Why would this be?

How do i find which Apple ID is associated with music in my iTunes? When I sync with my iPad and iPhone it tells me I have music, apps etc from more than five IDs. I am asked for PW for a number of now extinct accounts.

Go to Settings/icloud. The Apple ID at the top of the screen is the only one you need to be concerned about. That one MUST be a working ID, and you must know the password for it, or you will be unable to use the phone if it ever crashes, you want to update it, or you want to sell it.

Can I authorize more than five computers on one iTunes account?

Can I authorize more than five computers on one iTunes account? I have several PC's being used as HTPC's and I'd like to use iTunes on all of them. My three iPhones and three PC's have taken up all of my authorizations. If I need to create a second iTunes account, can it be linked to my existing account?

Todd, some suggested reading, none of which looks to me as requiring authorization as an iTunes device for Apple TV:

How to deploy a Webapplication on WAS more than one times on same server?

Hi all,
I 've a special problem:
In our web-app (some DC's) also stored propertie-Files. Now we would to deploy this application more than one times at same server using different WebContentRoots. (f.e. http://server/app1 and http://server/app2 a.s.o.)
We know, that we must create different EAR-Projects and refer the web-Module and configure the application.
But in the second application there it's recommended to change some properties.
How we can handle this in JDI without copy the web-application?
I hope my question can be understood.
Best Regards

Using Netweaver + WAS 6.40 2004 SP 13

Hi Sven,
as I'm new to NWDI, I cannot give you a 100 percent, field-tested solution. But have you already thought about using the Configuration-Adapter?
If you can change the source of your web-app, you could maintain the data formerly stored in property files using the configuration adapter of visual administrator. The SC <a href="http://help.sap.com/saphelp_nw04/helpdata/en/45/e7e14b517b42788a1c166f9f32455e/content.htm">configuration</a> allows you to access this data.
With this approach you can stick to one web-application and do the configuration work separately for each deployed application.
Best regards,
Frank

How to share more than one Time Machine folder

Hi,
With Snow Leo Server I found how to find how to share more than one Time Machine Folder but I can't see how to do the same with Lion Server, could you help me with that ?
The goal of that is to offer one TM folder per user which is located on a dedicated partition in order to limit the size of TM backups per user (150Gig).
In Lion, in can only share one TM folder for everybody and I didn'tfind if I can set a limit size per user...
Thank you in advance,

I have figured out a way to enable multiple backup targets.
However, it's one of these things I wouldn't want to describe to anyone except true programmer types, because everyone else has a 90%+ chance of messing up their system if they do something wrong.
It involves turning off file sharing, and then editing the plist files in /private/var/db/dslocal/nodes/Default/sharepoints/
The gist of it is this:
a) first create all the share points you later want to use for TimeMachine, and set them up for afp-only file sharing, also create one TM target, which you can either use later, or have there so the system has one entry it knows how to handle. I just made a bogus one that I'm not actively using.
b) turn off file sharing in Server.app
c) turn off TimeMachine in Server.app
d) now you can edit the files, the easiest is with Xcode, so you may want to install that first
e) for each sharpoint you made in a) there will be a corresponding .plist file in the location indicated, these are the files that need to be edited.
f) for each of these files
     1) the item0 string property in the timeMachineBackup array must be switched from 0 to 1
     2) a new key of type array with the name timeMachineBackupUUID must be created
     3) in the newly created array an item of type string must be placed with the value of a UUID, which can be created with the shell command uuidgen
g) make sure all the edited plist files are saved
h) turn on TimeMachine in the Server.app again
If all went well, you now should be able to go to one of your networked client computers and see all the time machine share points just created as options for being a time machine target.
Anyway, if you go that route: be careful, don't blame me if you muck things up...

Not able to load pages more than 3 times continuosly

Hi
JDeveloper 11.1.1.6, BPM/SOA 11.1.1.6, WLS 10.3.6, Database : MS SQL Server 2008 R2
I am not very sure if it is related to BPM or ADF, but it looks more like an ADF error..
We have a BPM process with some human tasks. The human tasks pages are ADF pages.
The pages / user tasks are opened properly for a few times, but does not load after that, until we close all the browser windows.
I am getting these errors intermittently whenever I try to open a human task page in the BPM Workspace.
(Common observation is that for the first few times the pages open properly. After more than 3+ times of opening the same task repeatedly, I a getting these 2 errors).
The page stops rendering after the last text '<div' tag.
Following are the 2 exceptions we see in the logs of the server.
We are using MS Sql Server 2008 R2 for database.
I tried with both Type 4 XA and Non XA versions of the JDBC Connections, but still getting the same error messages.
Can anyone please let us know if we might be missing anything.
Thanks for any help.

Hi,
depends on whether you control the BPM task flow or not. If you do, have a look at this thread for how to debug the problem
How to debug "Attempt to validate an already invalid RegionSite"?
Otherwise, post it to the SOA forum if this is initiated by their generated code. The most common reason though is that the task flow lacks a default activity. So if the default activity is somewhat calculated dynamically in your application then this may be a reason

Is there any way to get rid of this stupid feature in iTunes for Windows? You've subscribed to a podcast but have more than five unplayed episodes. iTunes will stop automatically downloading newer episodes.

s there any way to get rid of this stupid feature in iTunes for Windows?
You've subscribed to a podcast but have more than five unplayed episodes. iTunes will stop automatically downloading newer episodes. You may get the following message:
iTunes has stopped updating this podcast because you have not listened to any episodes recently. Would you like to resume updating this podcast?
You can click Yes to continue downloading additional episodes. Or you can just listen to any part of any episode and a new episode will download at the next update.

I believe that feature was added in order to reduce wasted costs to the Podcaster.
Podcasts incur costs - that have to be paid for, by someone. That cost will be the cost of hosting the Podcast on a server somewhere and more crucially (with regard to your point), the cost of the Podcast being downloaded to your computer. Every download costs the Podcaster money (typically, charged by bytes downloaded).
If that Podcaster pays for the whole thing personally, obviously they want to keep down any unnecessary cost to themselves. If the Podcaster is earning money for his or her Podcast (typically from advertising within the programme) then obviously, the advertiser only wants to pay for advertisements heard by listeners. So a download, not heard by the downloader, is waste of the Podcaster's money or no payment from the advertiser.
My own experience is that I only have to resume downloading once per programme. I'm usually several episodes behind on two different Podcasts that I follow, but I do not recall having to repeat the resume Podcast after that first time.

ReturnEvent not get called after search more than 10 times in LOV page

hi there,
I using ADF and Jdeveloper 10.3.1.2
In my project I have a form which called a LOV page for selecting multiple records and submit button sumup the values of each selected row of LOV and return to the main form and display added value on text field.
problem is when I search records more than 10 times or more I put search criteria and select row on each time. After click on submit the value of each row is sum up return on the main form but it not reflected on main form because ReturnListener not get called .
But when I select many rows more than 10 without searching then the ReturnListener get called when it returning on main form.
So should I do so that ReturnListener get called.
Is it any bug of ADF or Jedeveloper .

What if i have more than five computers to authorize itunes accoutn?, what if i have more than five computers to authorize itunes account?

itunes only allows me to authorize five computers. but what if i've used more than five computers in my lifetime with my itunes account?

Well, what i was tyring to do was re-download my purchased items. and the message I get is....
You have already authorized five computers.
you can still make purchases on this computer, but you will need to transfer them to an authorized machine or device to play them. if you wish to play purchases on this computer, you will need to first deauthorize a currently authorized computer.
BUY or CANCEL.
the thing is...as i mentioned before, i already deauthorized all the other computers. so i don't get why it is making me buy it again.

Is possible to execute the same executable vi more than 1 time (like notepad, for example)?

I have a Labview executable file that use serial ports to communicate with other devices. I need to execute the same "file.exe" more than 1 time, to control different devices simultaneously. When I double click on an executable been executed (from windows explorer), the file under execution comes to front. Is possible to execute the same file more than 1 time (like notepad, for example)?

Not the answer you are looking for I know..but still: Copying the application to another location is one possibility...if it has a different path it will execute separately.
(OR - build control of multiple devices into one and the same application... If you do not want to redesign the code to handle multiple instruments in the same VIs, you could clone the VIs within the same application...)

"You cannot authorize more than five computers"

I am unable to play any of my music that I have bought from iTunes music store because when I try to play my music on my new computer it says "You cannot authorize more than five computers". In fact, I only have four computers using my iTunes music account. Any suggestions?

hmmmm. perhaps check to see if you've ended up with multiple authorisations on one of those computers:
