OCIAttrGet() hangs after OCIStmtExecute()
I am trying to describe a select statement with OCIStmtExecute(....,OCI_DESCRIBE_ONLY); Everything seems to be fine up to the point where I want to do this:
OCIAttrGet(stmhp,OCI_HTYPE_STMT,&numcols,0,OCI_ATTR_PARAM_COUNT,err);
This call simply hangs. I have checked and double checked all parameters and all calls before this, and I am certain they are OK. What can be wrong? There are nothing in the alert log and The same connection has no problem with eg. OCIDescribeAny().
/jan
I'm using the following lines and it works fine (Server: Oracle 8.1.7 Linux / Client 9i Win2k):
CheckError(OCIStmtExecute(svchp, stmthp, errhp, (ub4)1, (ub4)0, (OCISnapshot *)NULL, (OCISnapshot *)NULL, (ub4)OCI_DESCRIBE_ONLY));
CheckError( OCIAttrGet(stmthp, OCI_HTYPE_STMT, &numcols, 0, OCI_ATTR_PARAM_COUNT, errhp));
Which SQL-Command are you executing? A SELECT-Command or something else?
Cheers
Johannes

Satellite U400-22n and Win7 - screen hangs after 5 min
Hi, This is my first post
Ive purchased a new U400 with Vista preinstalled, last week ; 2 days ago Ive upgraded to windows 7 32bit professional when I stared Installing it windows prompted me that it requires a full installation , so I done a normal full install, windows 7 installed normally .
Now my screen hangs after 5 min and windows gos black and reboots after 3-5 min, Ive downloaded all the drivers from the Toshiba site Ive used the auto detect, and installed the drivers one by one and tested if the reboot stops , Ive reinstalled windows now 4-5 time returned my copy to the shop and got a new copy of the windows DVD, its the same,
Please has some one any advice for me. As the shop Ive perched this from will not upgrade to windows 7 for me.hi Mather,
any bluescreens visible?
win7 32bit i guess...
you have to install all the drivers for win7 provided by toshiba in the right order!
first chipset and patchfiles if available...
i think a clean install will do the job!
make sure that the hdd is error free!
you can upgrade from vista 32bit to win7 32bit
but no chance to upgrade to a win7 64bit when a vista 32bit is installed... -
Iphoto hangs after upgrading to Yosemite and latest iPhoto version
It tells me the library needs upgrading, and starts to search the library. The progress bar suggests something is happening then hangs after about 99% completion. I have had to force close twice after several hours stuck at that point and then start the whole process from scratch when I restart.
Have you followed these instructions - http://www.fatcatsoftware.com/iplm/Help/rebuilding%20a%20corrupted%20iphoto%20li brary.html

Rebuilding a corrupted iPhoto library
If you have an iPhoto library that is corrupt and causing iPhoto to crash or otherwise be unusable, iPhoto Library Manager provides the ability to rebuild your library based on the information found in its library data files. Note that iPhoto also has a built-in rebuild function that can be sometimes be used to repair a corrupted library database. You can find instructions on how to use that on Apple's website at http://support.apple.com/kb/HT2638 (iPhoto 6 or later) or http://support.apple.com/kb/HT2042 (iPhoto 5 or earlier).
iPhoto Library Manager's rebuild works differently, in that instead of trying to repair the library in place, it creates a brand new library and tries to reimport the entire contents of the original library into the new one, including reconstructing albums, photo metadata, etc. Note that rebuilding a library has all the same limitations as other photo transfer operations as far as what can and can't be copied between libraries. Also, depending on how badly damaged the library is, iPhoto Library Manager may or may not be able to piece together some or all of the library metadata.
To start a rebuild, select the library you would like to rebuild, then choose the "Rebuild Library" item from the "Library" menu. You will be prompted to choose a location for the rebuilt library, and whether or not you want iPLM to scavenge orphaned photos it finds in the library package. Once you've made your choices, iPLM will examine the library and rebuild the library structure and photos as best it can, then display you a preview of what it was able to find. If your library is badly damaged and the preview is missing a lot of content from the original library, this can save you from going through with a rebuild that won’t end up being of much help.
Once you've had a chance to examine the preview, if you want to go forward and create the rebuilt library, click the "Rebuild" button in the upper right. iPhoto Library Manager will create a new library and start importing the contents of the original library into the new one.
Scavenging photos
In some cases, either the iPhoto library database is too damaged for iPhoto Library Manager to be able to salvage any information from it, or the library data is incomplete and there are photos that still exist inside the library package, but iPhoto has lost track of them. In these cases, you may want to check the "Scavenge orphaned photos" checkbox when choosing a location for the rebuilt library. After iPhoto Library Manager has read the library data as best it can, it will perform an additional pass through the package and locate any photos that are no longer referenced in the library database. Any additional photos that are found will be included in the rebuild, and a new "Scavenged Photos" album will be created in the rebuilt library containing any scavenged photos.

Am facing issue on my iphone 5s after updating to ios 7.1.1, every while the phone hang after lock it and cannot unlock and even cannot turn on the screen this is so annoying, kindly advice if i have to go back to the store as device still under warranty, and if its a hardware issue or software ??
Hello HaithamOkeely,
We've an article that provides the following troubleshooting steps that may help stabilize your iPhone.
If the device is unresponsive or if certain controls aren't working as expected, restart your device.
If the device remains unresponsive or does not turn on (or power on), reset your device.
If there is no video or if the screen remains black, verify that the device has enough charge to turn on:
If you are using an iPad, ensure that it's connected to the USB Power Adapter supplied with the device.
Let it charge for at least twenty minutes, then see if it starts normally.
If there is no image on the screen, press the Sleep/Wake button to attempt to wake the device.
If the screen displays a red battery icon, continue charging the device until the battery is fully charged. Learn more about charging iPhone and iPod touch, or iPad.
If the above steps do not resolve the issue, or the if the screen remains black or shows a persistent Apple logo, try restoring with iTunes:
Connect the device to your computer and open iTunes.
If the device appears in iTunes, select and click Restore on the Summary pane. Learn more aboutrestoring iOS software.
If the device doesn't appear in iTunes, try to force the device into recovery mode, and then restore it.
If the above steps do not resolve the issue, contact Apple.
iOS: Not responding or does not turn on

Powerbook G4 hangs after few minutes of usage
Since February 06 I have a PB G4: 1.67GHZ, model Powerbook5,8
Since this weekend it hangs after a few minutes of usage.
I tried a whole load of possible solutions, like resetting the RAM, removing the battery and holding the powerbutton for 5 seconds...I even held it once for half a minute, but that didn't help. Checking the harddrive with disk utility (tried it often, but only once did the PB work long enough to get the end result: hard drive is healthy).
Often, when it hangs, I can get it to work by simply turning it off and on again. That gives me another window of 2 minutes of usage! Handy throughout the day when I need a file, or a document: I simply boot the machine, get the file and shut it down.
Carbon copy to an external HD does not work: the system hangs a few minutes after copying.
I installed a utility named applejack, and the first time I tried it, I got an interesting error: there were errors with the USB controller or USB bus, and system hangs. I didn't make a screenshot so this is out of the top of my head.
This was interesting because when I tried to make a HD copy (and believe me: I tried lots and lots of times), the system freezes first, and then an error about not unmounting a device popped into the screen. As if the touchpad, keyboards, and all other i/o devices stop working, and the system goes on for a few seconds more.
Sometimes the system just hangs, sometimes I get that black kernel panic screen.
Just before writing this, I tried the hardware test on the install CD once more:
Held down the option key, chose the hardware test -> quick test and..
system hangs after completion of the test
A message appeared in the bottom-left corner. Several lines of information, starting with:
"ERROR, Write to location ZERO detected!!, Loc zero was originally zero
Current File: Localization/en/Scripts/enAHTscript.sc"
etc
I live on a nice island in the Caribbean, so popping into the nearest Apple store means getting on a flight to Miami first.
What -if any- are my options? Is there something I can try to do myself before shipping it to Apple? Opening the case, checking this or that?
By the way, I originally posted this in the Titanium folder, but someone mentioned that I might actually have a Aluminum PB.
see http://discussions.apple.com/message.jspa?messageID=2074854#2074854hi joeuu,
I have 1.5GB mem: one 512 stick and one 1GB and I already tried the sticks one at a time: it hangs with the original 512, it hangs with the 1GB and it hangs with them together in both possible slot settings.
I managed to copy the panic.log in /Library/Logs/ and here it is:

Now what can we read from this?
I see in here "AppleUSBTrackpad" and "AppleUSBOHCI".
Referring to my original post: I have seen an error (a few days ago, when working with applejack) that also mentioned USB.
I'm very afraid that this is a hardware issue. Reading through some other posts, I saw something about a ribbon that gave problems. What are your thoughts? -
Database hangs after retrieving some records....
hi,
I create a two level B+-tree index, for the first level i'm using key as logical database name, for the second level B+-tree i'm using some other field in my data. I am retrieving the records based on logical database name. I am using C++ to implement my index.
In the following code i'm retrieving records from database. Program is behaving differently for different logical database names. For example in my database i have around 4 lakhs records with logical database name 'A' and around 1 lakh of records with logical database name 'B'. The following code displays all B records but programs hangs after retrieving some A records.

Problem in reading data from serial port continuously- application hangs after sometimes
I need to read data from two COM port and order of data appearance from COM port is not fixed.
I have used small timeout and reading data in while loop continously . If my application is steady for sometime it gets hangs and afterwards it doesnt receive any data again.
Then I need to restart my application again to make it work.
I am attaching VI. Let me know any issue.
Kudos are always welcome if you got solution to some extent.
I need my difficulties because they are necessary to enjoy my success.

What do you mean, "not fixed?" If there is no termination character, no start/stop character(s) or even a consistent data length, then how can you really be sure when the data starts and stops?
I probably misunderstood you though. Assuming the last case is not ture - there is a certain length to the data - then you should use the bytes at port, like in the otherwise disastrous serial port read example. In this case, it's NOT disastrous. You have to make sure that you read all the data that came through. Right now you have no idea how much data you just read. Also, if this is streaming data, you might want to break it out into a producer/consumer design pattern.
Not fixed means order is not fixed, data from any com port can come anytime. lenght is fixed, one com port have 14 byte and other 8 byte fixed..
Reading data is not an issue for me as it works nice but I have a query that why my application hangs after sometime and stops reading data from COM PORT.
Kudos are always welcome if you got solution to some extent.

Lenovo T61 (Product 6458-W2R): explorer.exe hangs after logon - WinXP SP2
+++ english below +++
[german/deutsch]
Wir setzen in unserem Unternehmen mehrere ThinkPad T61 ein. Bei einigen dieser ThinkPad T61 (und nur beim ThinkPad T61!) haben wir inzwischen ein seltsames Phänomen, welches im Laufe der letzten 1-2 Monate auftrat und noch auftritt. Dieses Phänomen trat nicht gleichzeitig auf, sondern nacheinander. Und es tritt willkürlich auf. Der jüngste Fall ist gerade 1 Tag alt. Inzwischen sind 6 ThinkPad T61 davon betroffen.
Alle ThinkPad T61 sind Mitglieder einer Domäne (Windows Server 2003) und durchlaufen ein Loginscript. Das Loginscript beinhaltet Batchbefehle, Kix32 (für das Mappen von Netzwerklaufwerken und Druckern) und Teile der Matrix42 Empirum Management Software (für Softwaredistribution und Inventarisierung). Es werden Gruppenrichtlinien angewendet. Es werden via Matrix42 Empirum automatisch die neuen Patches und Updates seitens Microsoft auf alle Computer verteilt. Alle Computer erhalten eine unbeaufsichtigte/standardisierte Installation via Matrix42 Empirum Management Software (ähnlich einem Image und der unbeaufsichtigten Windows-Installation). Auf allen Rechnern ist Windows XP mit Service Pack 2 installiert. Spezielle Software ist in der Regel nicht drauf, nur Microsoft Office 2003, der aktuelle Acrobat Reader sowie die aktuellen Standardplayer: Windows Media Player, Quicktime Player, RealPlayer, VLC media player. Ggf. noch Nero 7 Standard bzw. Platinum (Spezielle Version). Alle IBM/Lenovo ThinkPad verwenden zusätzlich die IBM/Lenovo-Utilities „ThinkVantage“. Das Phänomen tritt unabhängig davon auf, ob das ThinkPad T61 in einer Dockingstation betrieben wird oder nicht. Es ist auf jedem Computer in der Windows Registrierung eingestellt, dass der Desktop erst geladen wird, wenn das Loginscript durchgelaufen ist.
Nun zur genauen Fehlerbeschreibung:
Manchmal kann es bei einem Kaltstart vorkommen, dass nach der Anmeldung und nach dem Loginscript –während der komplette Desktop und die Startleiste bereits sichtbar sind und noch einige Dienste geladen werden– sich die explorer.exe aufhängt. Die Startleiste lässt sich nicht bedienen. Ebenfalls lassen sich dann auch auf dem Desktop keine Symbole doppelklicken.
Wir setzen auch andere Computer ein, wo dieses Phänomen nicht auftritt, u.a.:
- HP-Computer (Desktops, Evo SFF Series)
- Fujitsu-Siemens-Computer (Desktops, ESPRIMO E Series)
- IBM ThinkPad T20/21
- IBM ThinkPad T40/T41/T42
- IBM/Lenovo ThinkPad T60
Das Problem tritt nur auf den noch relativ neuen ThinkPad T61 auf.
Wir haben bereits einen ziemlich ähnlichen Fall unter…

Unfortunately, I’m not fluent in the english language.
We use a few ThinkPad T61’s in our company. Meanwhile, at some ThinkPad T61’s (only ThinkPad T61!) we have a strange problem. This problem appears since the last 1-2 months and it still does exist. This problem does not appear at the same time, it does appear successive. And it appears random. The last case is 1 day old. Meanwhile, 6 ThinkPad T61 are concerned.
All ThinkPad T61 are members of a domain (Windows Server 2003) and do execute a logon script. The logon script contains Batch commands, Kix32 (for mapping network drives and printers) and parts of the Matrix42 Empirum Management software (for software distribution and inventory scan). Group policies will apply. Patches and updates will install on every computer via Matrix42 Empirum automatically. All computers get a default/unattended installation via Matrix42 Empirum Management software (everywhere between an image and an unattended Windows installation). All computers have installed Windows XP with Service Pack 2. As a rule, special software isn’t installed, only Microsoft Office 2003, the actual Acrobat Reader and the actual default players: Windows Media Player, Quicktime Player, RealPlayer, VLC media player. Sometimes, there is installed the Nero 7 Standard or rather Platinum (Special Edition) yet. All IBM/Lenovo ThinkPad use IBM/Lenovo-Utilities „ThinkVantage“ additionally. The problem exists if the ThinkPad T61 is connected to a docking station and also if the ThinkPad T61 is disconnected from a docking station. On every computer exists a registry key which arranges it that the desktop only will be loaded after the logon script did run.
Now the detailed error description:
Sometimes the explorer.exe hangs after the cold start. i.e.: The desktop (with icons and task bar) appears complete. But the computer hangs if you try to click on the task bar or double click on any icons. The computer will only run if we kill the process ‘explorer.exe’ and if we restart the explorer.exe.
We use also other computers with the same installation and the same group policies where the problem does not exist, for example:
- HP-Computer (Desktops, Evo SFF Series)
- Fujitsu-Siemens-Computer (Desktops, ESPRIMO E Series)
- IBM ThinkPad T20/21
- IBM ThinkPad T40/T41/T42
- IBM/Lenovo ThinkPad T60
Only the new ThinkPad T61’s have this problem.
We have found a similar case at…

Vielen Dank / Many thanks!I would run System Update and make sure I had all the updates available.
Another thing to try is:
1. Right-click on My Computer and click Properties
2. Click on the Advanced tab
3. Click on Settings under Performance
4. Click on Data Execution Prevention
5. Click on Turn on DEP for all programs and services except those I select, then check Windows Explorer
We had to do that to some machines here after a push from corporate of the new ScriptLogic.This solved the problem.

Video hangs after burning on a DVD
Hi,
after burning a project with menus and several chapters, I notice the DVD is hanging after a few chapters. My DVD burner itself should be ok, I got no hardware failures and it's working fine with Nero Burning ROM. Any suggestions??
Tx a lot,
KristofYou used iTunes to burn the CD? If so, it should work. The question is, did you choose "back up to disc," or did you create a playlist, and choose "Burn playlist to disc?"
If you do it the first way, you are just saving the actual music files (not in CD format) to a CD.
If you create playlist and burn playlist to disc, you are making an actual Audio CD that will play in any CD player.
If you are already using the second method, are you using a CD-R, or CD-RW? Some players have problems w/RW's.
Btw, iTunes songs are not MP3 format, so I don't think you'll be able to find a "converter." LOL -
Queries on oracle hang after index creation
Hi,
I have a problem where queries issued on an oracle database hang after I create indexes on some of the tables used by these queries.
I have a script where I drop indexes :
DROP INDEX EVP_PCON00_CDSITC_IX;
DROP INDEX EVP_PCS202_STIMP1_IX;
DROP INDEX EVP_PECT00_ONAECT_IX;
DROP INDEX EVP_PVAL01_ONAVAL_IX;
After this script I load data into those tables.
Then I launch another script where I recreate the indexes I just dropped :
CREATE INDEX EVP_PCON00_CDSITC_IX ON EVP_PCON00(CDSITC) TABLESPACE TS_ODS_INDEX;
COMMIT;
CREATE INDEX EVP_PCS202_STIMP1_IX ON EVP_PCS202(STIMP1) TABLESPACE TS_ODS_INDEX;
COMMIT;
CREATE INDEX EVP_PVAL01_CDORIV_IX ON EVP_PVAL01(CDORIV) TABLESPACE TS_ODS_INDEX;
COMMIT;
When the script ends, I try to execute a query using some of the tables I created indexes on :
SELECT ...
FROM ....
WHERE ....
The query never return a result set, it just hangs, I look at the session browser in toad and the scan of the first table used in the query hangs.
When I drop those indexes and re execute the query everything works fine.
Thanks

IMovie Hangs After Full Quality Sharing Is Complete
Hi,
Why does this happen? I did a Full Quality Share on a 2-1/2 hour multi-clip movie (using Share Selected Clips Only). The export progress dialog hung after the export was clearly finished. I eventually had to Force Quit iMovie.
The exported movie looks fine in QT Pro. However, Movie Properties in QT shows that this movie is 24 frames longer than what I exported from iMovie. Doesn't seem to be a big deal, but annoying nonetheless.
I'm more concerned about iMovie hanging after a long movie export as described.2-1/2 hour multi-clip movie (using Share Selected Clips Only)
so, your project is in timeline even longer then 150min? how much did you import into iM, to create such a "beast"? must be a gigantic project, hm?... Titanic II... ;-))
iM is a consumer product, we do read of reports here, that from some point of size (imported data, length, complexity of project), iM is a little "overwhelmed..." esp., iM is part of iLife, meaning, mainly meant exports go to tape (=60min max.) or iDVD (120min max.)
secondly, MacOsX is a UNIX system, which makes excessive use of socalled temp-files on (startup-) harddrive... it is recommended, not to overcrowd the drive 80 - 90% of max.
probably, your ~35GB of data transfer from a ~60GB project was simply too much for your Mac?

My ipod cclassic 80gb is hang after trying dat press and hold method then also its not working please tell me solution
Thanks for your response and good luck wishes, I suspect I will need them!
In principle, I agree re: the manufacturer's warranty. However, I am pretty upset that this is now my second iPod to develop a critical fault within weeks of the warranty expiring, and frankly, it is not unreasonable to expect a state-of-the-art $500 electronic device to last well beyond one year of life.
I agree talking to Apple is not likely to do me any good (the clue is in how impossible they make it to talk to them in the first place) - but that is not necessarily OK. I expect I will have to pay money to get the battery replaced - again, not OK (full stop - but especially given the cost of the device and the money I have spent with Apple). Yes, the batteries have a limited lifespan, but it should last longer than this (and surely, I should notice a gradual decline in its functionality, not an instant stop).
I will try Deggie's suggestion (see my reply post), but probably won't hold my breath (think I have already done this). I probably will have to get the new battery - and probably under my own steam. It is a principle at stake and I feel I should be able to let Apple know how I'm feeling - and am frustrated that they make this virtually impossible. It sends the very clear message that they are not interested in listening to their customers.
