X11vnc dies/exits after a single successful session

Well, I've set up x11vnc on the server (without a .x11vncrc which is not needed) and I start it as user like this:
x11vnc -rfbport 41333 -rfbauth /home/medja/.vnc/passwd &
The log after starting it looks like this (all good):

I'm able to use it without problems but when I disconnect, the server just dies.
Of course I can't connect to the box via vnc anymore.
ps -A | grep vnc shows nothing after that. It's definitely gone.
Does anyone have an idea what is wrong here? BTW, the same happens on another arch server I've set up for a friend but I'm not able to compare the logs and all that but he also can only connect to the vnc server once.

This is how it's meant to be.

You should take a look at the "-forever" option.

Connecting Window iTunes Store appears after every single search character

Hi Community,
if I use the search in iTunes 10.3.x Store, after tipping a single character always a separate window appears with the message "connecting to the store" - the window appear after every single character of a search e.g. "Madonna" and it will lasts minutes to get a result!
It looks like here: http://dl.dropbox.com/u/1426841/itunes.png
Did anyone have a idea what to do?
I've just tried following steps:
clear iTunes caches
delete iTunes plist's
delete and reinstall iTunes
perform pram reset
latest iTunes updates
Nothing helps at all to cover this problem!
This problem exits since a few month (starting with iTunes 10.2.x), just starts from one day to another without any change at the OS.
Thanx in advance for any helpful ideas ;-)

Try clicking Store>Authorize This Computer in iTunes.
If that doesn't take care of it, take a look at this Apple document -> http://support.apple.com/kb/ts3297.

Hi, I finally got lucky and past the "other" memory status issues when syncing. Now I'm "waiting for changes to be applied" sync stuck all night (itunes yesomite iPhone 6 plus). is this a bug? I have not had a single successful sync with yesomite.

hi, I finally got lucky and past the "other" memory status issues when syncing. Now I'm "waiting for changes to be applied" sync stuck all night (itunes yesomite iPhone 6 plus). is this a bug? I have not had a single successful sync with yesomite.
please help. this issue prevents music from syncing. I have set the sync setting to convert songs to 192kbps AAC to save space, I figure that could slow the sync
down, but it's hanging indefinitely (I've left it for 24 hours with out it completing.)
the the only music that appears on the phone are songs purchased from the iTunes Store. 95% of my collection are rips from my CDs.
thank you for any help!

Yeah it's pretty sad that $1000 phone they put out you such cheap memory It causes issues, I have iPhone 6+128 GB actually this is the second brand-new one they gave me because they keep affording it trying to act like that's not the issue because they're too stupid to know how to check what memory is in each one before they give it to me when I have told them multiple times my back up runs perfectly fine on two 5s phones and a 6 64GB of course running MLC memory.
I told them it's because just like the write ups say I have 809 apps but I have not even put all my music on the phone so I'm still running 50 to 60 gigs free and it crashes and reboots itself sometimes in multitasking and more often than it does that in between multitasking I get a black screen for 1 to 2 seconds in between apps and upon start up the Apple logo screen will flicker and do weird things, One of the genius idiots asked me if I could just delete some of my apps, really that's the answer to fix the phone the customer needs to limit the amount to apps they put on their phone, why the **** get a 128 gig if you can't put on anything you want to it guess they need to start selling them saying you can only put a limited number of apps on them, it's really is a **** joke, I have over $20,000 of Apple merchandise easily and always get the new phone every year but I'm starting to reconsider my decisions in the future because this company is starting to go downhill, The reason water not recalling the phones is because they're dealing with their top-of-the-line thousand dollar phones in this case and most people don't have over two or 300 apps so they're not having as many issues, so basically they have messed up phones they just don't know it in their hands and Apple is just too **** greedy to recall the phones, they'd rather sell customer spends that only work half ***.
Stuff like this will be the downfall of their company, all the people that stay with them because as long as you don't jailbreak their stuff it normally just works without issue will be soon jumping ship if stuff like this keeps up, because I can guarantee they got me thinking now.
not that I wanted to know or should I be expected to but I even offered for them to open up my brand-new phone and just replace the memory to MLC memory which is something I shouldn't have to do with a brand-new **** phone, they should just make one with the right memory and give me a new phone, actually just don't sell customers that buy the top-of-the-line phone from you trash ones in the first place that would be a great option.
what burns me up the most is when you talk to AppleCare and Genius Bar they try to act like the issue isn't there and they're unaware of it, they say that Apple hasn't come out with any information about it, yeah that's because they don't want to recall the trash.
Apple has became nothing better than your run-of-the-mill company, android is becoming just as good as they are sad to say this since I have been an Apple fan for so long but there is no excuse for BS like this they have been looking for options to fix my phone for a month now this is not the way you should treat loyal customers, I would've been better off keeping my 5S and in the future just switching to android.
it's pretty sad that the company has no idea how to check which memory is in their **** phone and even after I offered to let them just replace the memory in my new phone by opening up my brand-new phone to replace it they have no idea how to do that either, yeah Genius Bar sure, I think that should change the name to idiot bar and Apple don't care instead of Apple care.

After burning a successful DVD in iDVD out of FCPX, how can I see the settings it used?
So I finally burned a DVD out of a Apple Pro Res file into iDVD in PAL format. My question now is how can I find out what the exact burn properties were so that I can apply the same burn properties to a project in Compressor 4?
Is it possible to see what iDVD did?

I don't know any way you can interrogate iDVD to reveal settings to the extent that you can in a Compressor project. What you could do is open up the show's VOB in MPEG STreamclip, go to File and Reveal Stream Information; that will at least give you some rudimentary info like average bit rate. Perhaps someone, with more iDVD experience, can chime in here.
The broader question is why use Compressor at all if your current workflow is doing the job to your satisfaction?
The value of Compressor is that it gives you control over the many parameters that affect size quality. and playability. The Compressor presets can give you a starting point for DVD delivery, Web, etc. From those presets, people typically experiment by adjusting the parameters until they get the desired results for their specific show. It's a little bit science and a little bit art. After experimenting, you may be able to get slightly better quality for the project you've successfully burned in iDVD by using Compressor and something likeToast…or maybe not.
Good luck.

After install of 8.1.5 SQLLDR.EXE wont exit after sucessful load.

After installing 8.1.5, SQLLDR.EXE wont exit after sucessfully loading a table. My DOS window just hangs. Has anyone had this problem? Version 8.1.5 is the highest license we have. I was on 8.0.5 and it worked ok.

Sorry to reply to my own post but this may help someone else.
The problem is that the Solaris 10 Express install doesn't install the /kernel/misc/sparcv9/kbtrans module. I just copied it before I rebooted after the first CD install.
(1) At the <Press Return to reboot the system> {"!" exits} prompt, enter "!"
(2) The new root partition will be mounted as /a.
(3) Copy the kbtrans file
cp -p /kernel/misc/sparcv9/kbtrans /a/kernel/misc/sparcv9/kbtrans
(4) Reboot
This is just a workaround - Sun needs to fix the install.

No bootable drive after installing windows successfully

I am trying to install Windows XP/Vista 32 Bit On Intel Mac Notebook through BootCamp.But after installing windows successfully,when it reboot?resatrt,It gives me error message that NO bootable Drive ,Press any to key to continue.......
I have Downloaded Windows XP/Vista 32 Bit ISO format and burned it on my DVD through Disk utility.I can install windows successfully but when it restarted then it gives that message.However I am able to locate windows hard drive after holding the Option Key and when I choose the windows HDD (BootCamp),It gives me same error.
I started the installation in osx using boot camp, and the windows was completely installed, even the boot camp driver for windows was installed and there are options to restart into either windows or mac osx.
But when I restart the machine and choose to go into windows, it just can not boot, saying no bootable device. If I insert the installation disc into the drive, then I restart and go to windows, it can boot successfully.
Please Help.
Much appriciated.

While we all have MacBooks in this forum not all of us use BootCamp. There's a BootCamp Support Community where everybody uses BootCamp. You should also post this question there to increase your chances of getting an answer.

Deleting Pictures from my I Book after a Time Machine session ?

Hello out there, my dear wife has allot of Pictures on her I Book and would love to delete them to free up space ! we ever so often back up to Time Maschine..if i deleted all her Pictures after a back up session..will the pictures be reloaded to her I Book at the next back up ? if yes..what would you recomend her doing so that she can free up her I book and still be able to access her pictures in the future ?

Put them onto an external drive and set Time Machine to back it up as well. If they exist only on the backup, they'll get deleted from it when that drive runs out of space.

Single Database Session Per User in ADF/BC Application

Hi, I am using ADF with BC (JDeveloper 11.1.1.1). My application contains multiple application modules, each connected to the same JDBC data source. On the app server, I have configured the data source to use Identity Based Connection Pooling.
My current configuration is resulting in numerous database sessions for each user. I have a requirement to use only a single database session per user HTTP session. Is there any way to configure the application modules to achieve this?
Thanks,

Hi,
use a single root Am module and make sure the others are used as nested modules. This will create a single connection

RMI server exits after 10 minutes

Hi
I have a strange problem: The rmi server exits after about 15 minutes when using my own socket factories. The reason seems to be, that only daemon threads are left in the servers VM.
If I add code like:
while(true) {
try {
Thread.sleep(10000000);
} catch(Exception e){}
to the main method, the server continues to run as desired, the main thread is not a daemon thread.
I checked the accept method of my factory, it runs in a daemon thread.
Is there any configuration property to specify that the server should run forever?
BTW: the server does not exit when using no own socket factories.

No, I don't export manually. However, isn't that the job of the naming service?
Calling export causes an "Object already exported" exception.
Here is the complete working main code that starts the server (removing the endless loop will cause the server VM to terminate after about 15 minutes of inactivity):
public static void main(String args[]) throws Exception
TClientSocketFactory client = new TClientSocketFactory();
TServerSocketFactory server = new TServerSocketFactory();
client.setServiceName("authtest");
server.setServiceName("authtest");
AuthImpl obj = new AuthImpl(client, server);
Naming.rebind(
"//" + InetAddress.getLocalHost().getHostName() + "/AuthServer",
obj
while(true) {
try {
Thread.sleep(10000000);
} catch(Exception e){}

Premiere Pro CS3 now exits after loading

After using premiere pro cs3 for quite a while, all of a sudden it exits after loading. I'm not sure if this is an Adobe problem or a Norton problem or a machine problem. It happened after a power failure, and while I was running premiere at the time, my power backup let me close the file and shut down premiere before it too died.
The computer is working fine with all other programs, including Encore & Photoshop. I just can't run Premiere. The other strange thing is that I can no longer access the Adobe site from that computer. The site starts to load then hangs forever.
I tried re-installing Premiere, no-luck. Then I downloaded the last update to CS3 (on another machine because the Premiere machine won't connect to the site) and tried to install it. No dice. The install hangs forever with "installing" on the screen.
I thought maybe there was an "installer" or "updater" problem, but can't figure it out.
Anybody have any suggestions?
Thanks.
Brad Tyrrell

Hunt,
Thanks for the reply.   I'll try that too.
A suggestion I got over at the DV board was to create a new admin account in XP and try opening premiere under that.   That worked!   Unfortunately, since I created my projects under the old admin file, I don't have access to them under the new one.   I'm copying files to a different folder at this point, but I know Premiere doesn't like that.
If deleting the preference file works, it'd be a lot simpler.
Thanks.
Brad
By-the-way, how did you get your screen name to not be your email address?   I can't seem to do it.   I went into my account and changed things, but the forum seems to insist that my screen name is my ID which seems to have to be my email address.

User Exits For Billing
o USEREXIT_NUMBER_RANGE (Module pool SAPLV60A, program RV60AFZZ)
The internal number range used in the standard system is specified
in the billing type table and can be changed in this user exit. This
user exit is only called when the billing documents is created.
o USEREXIT_ACCOUNT_PREP_KOMKCV (Module pool SAPLV60A, program
RV60AFZZ)
In this user exit additional fields for account determination that
are not provided in the standard system are copied into
communication structure KOMKCV (header fields).
o USEREXIT_ACCOUNT_PREP_KOMPCV (Module pool SAPLV60A)
In this user exit additional fields for account determination that
are not provided in the standard system are copied into
communication structure KOMPCV (item fields).
o USEREXIT_NUMBER_RANGE_INV_DATE (Module pool SAPLV60A, program
RV60AFZC)
Depending on the number range, table TVFKD is used to set the
billing date (country-specific requirments in Italy).
USEREXIT_NUMBER_RANGE is automatically deactivated when this user
exit is being applied.
o USEREXIT_FILL_VBRK_VBRP (Module pool SAPLV60A, program RV60AFZC)
This user exit is only called when the billing document is created.
It is used to provide the header and the item of the new billing
document with deviating or additional data.

User-exit after updating PO from Order response ?

Hi All,
We are looking for a user-exit after the Purchase order is updated from an order response.
With this user-exit we would like to trigger a WF to the user to carry out transaction YE22N, with the WF the user(PO creator) can execute and update the PO.
Any feedback, tips would be helpfull and for sure points reward.
Thanks & Regards,
Nameeth

Hi Anand,
Sorry for the confusion., try to explain here.
During the updation of PO from inbound ORDSP IDoc, we have a transaction YE22N to confirm if the changes in ORDSP is accepted or not.
So we would like to automate this so that after the PO is update/saved from ORDSP IDoc, then we can trigger a workflow to send email to the PO creator.
If its still confusing then, "I would like to know if there is a user-exit or if Workflow can be triggered after updating PO" ?
Regards,
Nameeth
