What cause indexes to be corrupted?

I've an application that need to rebuild the indexes everyday or twice a day. I don't know why I have rebuild them so often. It's a big difference performance after the rebuild.
Thanks

The application is from Xeror (Docushare) and the back ends is Oracle. The application only has 9 indexes. Note, when I drop and recreate it performs much better and rebuild. That's too I don't understand too.

What cause "missing index" happen ??

what cause "missing index" happen ?
and what is the effect of missing index ?

It depends on the table.
Some BW tables have indexes on DB only since DDIC does not allow to create non-unique primary indexes. For any wanted difference an entry in table DBDIFF is created.
It has has to be analyzed if it's an wanted or unwanted difference.

What caused the iBook problem?

I'm writing this for my wife, as she's unable to use her iBook for more than a few minutes before it locks up.
I'm serving in the military overseas. My wife and I both use Apple products to chat, email, etc. When I spoke to her yesterday, she was frantic. Her iBook G4 apparently started making a strange noise and then stopped working altogether.
I asked her what she had tried, and she explained that she spent over an hour on the phone with Apple support (I knew AppleCare might come in handy). The first support person she spoke with was, for lack of a better term, an idiot. This was confirmed by the third support person she spoke with. I'll explain later.
The problem was that when she tapped her spacebar to wake up the computer, it didn't wake up completely. She got a grey screen, Apple logo, and that was it. I told her to be patient, that maybe it was reseting after an update (that was before I knew about the 10.4.6 update being available).
Her computer auto-updates every Monday.
I had her turn off the computer by holding down the power button. I then had her disconnect the power cord and remove the battery. I did this on a hunch (just in case the computer had a heat problem). She reconnected the power cord, pressed the power button, and it was back up and running - for about 5 minutes.
Then the computer began making a not-so-funny noise again, and the spinning-beach-ball-of-death reared it's ugly head and wouldn't go away.
The first support person had her use the install/boot disk that came with the computer. That was Panther. We're using Tiger. Bad idea.
When the boot/install disk did not appear to be working, the first support person had her abort, and she was prompted with little phrases like "are you sure you want to quit, doing so now may damage your files" or something like that.
He just had her keep clicking "OK" and eventually got tired of talking to her and told her the hard drive was bad and that she was SOL.
The second support person was apparently too busy to troubleshoot any further and cut directly to "sorry, you're SOL".
The third support person was a little more helpful in that he talked her through connecting the iBook to her G5 PowerPC iMac to attempt pulling the files over to the iMac (she had already resigned herself to the fact that the iBook hard drive was on it's last leg).
She had asked the first support person about doing this and he said that if the files were corrupt on the iBook, they might corrupt the iMac, and that it was a bad idea. Not a very bright guy, considering the files would be copied to a folder, and wouldn't overwrite the iMac's system files.
She started to transfer files and the iBook froze again. She repeated the steps I had her do earlier, managed to get a CD in the the drive, copied a few folder successfully to the CD, checked the CD to see if the files were there (success!) but then the iBook died before she could get the CD out. She's working on holding down the track pad button while rebooting to see if it'll spit out the CD as I type this.
So, in addition to wanting to know how to resolve the problem, I'd like to know what caused it.
What caused so many people to have alleged hard-drive problems within a day or two of each other?
Is this Apple's first virus?
Is this the work of a disgruntled Apple employee working in the updates department?
Is this an evil Apple plot to force us to by MacBook Pro's that won't run Virtual PC?
Will running the 10.4.6 hurt or help the situation?
Why is there such inconsistency in Apple support and aren't they supposed to log their trouble-shooting steps performed thus far?
My wife has been using Mac's for over 9 years. I've only been using them for 2 years. Up until now, I've had a lot of confidence in Apple to be a solid platform, even if not the fastest platform. This experience is not inspiring me to purchase another Apple computer.

SOL?
Her files probably won't fit on a CD; unless she has less then 700Mb.
1."Is this Apple's first virus?"
Negative
2. "Is this the work of a disgruntled Apple employee working in the updates department?"
No, I don't think so. Apple tries these out to try and avoid problems with their updates. Things happen that are not expected. They wouldn't put anything out unless they thought it was ready.
3. "Is this an evil Apple plot to force us to by MacBook Pro's that won't run Virtual PC?"
First off, look at #1 and think about what platform is notorious for virus problems (Mac has had not had any virus out breaks so far). There have been some "malware/macro" software that was meant to mess with Apple Computers. The most recent that was was over exaggerated was nothing special; MacWorld worked pretty hard to get it to effect their machine. As long as you know what you are downloading and where you are getting it from, you should have no problem.
If you want VPC to work on a MacBook Pro; don't look to Apple. You should talk to Microsoft's Mac Department because Apple announced the Universal Binary switch a long time ago (with developer help) so that software companies could make the switch easier. If anyone is to blame; its Microsoft [they are busy working out their problems with Vista; I am guessing it will be awhile before you see VPC for MBP;) ]
"Will running the 10.4.6 hurt or help the situation?"
My opinion would to just reinstall Mac OS X after backing up the hard drive. That would probably fix your problem. Once OS X is installed; update the software.
"Why is there such inconsistency in Apple support and aren't they supposed to log their trouble-shooting steps performed thus far"
Once in a while Apple's personnel may make human errors. The second one you talked to may have seen her work-up and just reiterated what was said. They have resources we don't, but they can't really go beyond them because they can't see the product, and they are just call support. You may have to send it in.
So in 9 years, you have had this one problem. We can't really tell you what is wrong with the computer because we can't see it ourselves; we can only give suggestions/ideas. Tell them her story, explaining her situation (military etc) and then see if they can help. She may want to bring it into her local Apple Store/Reseller. She can make a reservation on the website or at the store. She can get better feedback in person.
Just some of my thoughts,

What causes BUFFER GETS and PHYSICAL READS in INSERT operation to be high?

Hi All,
Am performing a huge number of INSERTs to a newly installed Oracle XE 10.2.0.1.0 on Windows. There is no SELECT statement running, but just INSERTs one after the other of 550,000 in count. When I monitor the SESSION I/O from Home > Administration > Database Monitor > Sessions, I see the following stats:
BUFFER GETS = 1,550,560
CONSISTENT GETS = 512,036
PHYSICAL READS = 3,834
BLOCK CHANGES = 1,034,232
The presence of 2 stats confuses. Though the operation is just INSERT in database for this session, why should there be BUFFER GETS of this magnitude and why should there by PHYSICAL READS. Aren't these parameters for read operations? The BLOCK CHANGES value is clear as there are huge writes and the writes change these many blocks. Can any kind soul explain me what causes there parameters to show high value?
The total columns in the display table are as follows (from the link mentioned above)
1. Status
2. SID
3. Database Users
4. Command
5. Time
6. Block Gets
7. Consistent Gets
8. Physical Reads
9. Block Changes
10. Consistent Changes
What does CONSISTENT GETS and CONSISTENT CHANGES mean in a typical INSERT operation? And does someone know which all tables are involved in getting these values?
Thank,
...

Hans, gracias.
The table just have 2 columns, both of which are varchar2 (500). No constraints, no indexes, neither foreign key references are in place. The total size of RAM in system is 1GB, and yes, there are other GUI's going on like Firefox browser, notepad and command terminals.
But, what does these other applications have to do with Oracle BUFFER GETS, PHYSICAL READS etc.? Awaiting your reply.Total RAM is 1GB. If you let XE decide how much RAM is to be allocated to buffers, on startup that needs to be shared with any/all other applications. Let's say that leaves us with, say 400M for the SGA + PGA.
PGA is used for internal stuff, such as sorting, which is also used in determing the layout of secondary facets such as indexes and uniqueness. Total PGA usage varies in size based on the number of connections and required operations.
And then there's the SGA. That needs to cover the space requirement for the data dictionary, any/all stored procedures and SQL statements being run, user security and so on. As well as the buffer blocks which represent the tablespace of the database. Since it is rare that the entire tablespace will fit into memory, stuff needs to be swapped in and out.
So - put too much space pressure on the poor operating system before starting the database, and the SGA may be squeezed. Put that space pressure on the system and you may enbd up with swapping or paging.
This is one of the reasons Oracle professionals will argue for dedicated machines to handle Oracle software.

What causes ipod to go into disk mode

I have an older ipod nano and out of the blue for no reason the other day when i picked it up it said something about how i needed to use itunes to restore. When i plug the ipod into itunes in says something about corrupted files and the ipod needs to be restored to factory settings. Now, i have read a lot about ways to try to salvage this but resetting etc. and when i do this i get a check mark that says "okay to disconnect" and above it it says "disk mode" But what causes this in the first place? I never plugged it into a computer and ejected it improperly. One day it works fine and the next it doesnt and im going to have to lose all my music because of it! So again, what exactly causes this to happen? Is it something i may have done or just a flaw in the device?
Thanks,
Bryan

Yeah, I've had this happen to me too. Unfortuantely its just one f the many joys of owning an ipod/apple product. I'm not exatcly sure WHAT causes this to happen, but if you hold down the center and menu button down at the same time, the disk mode screen should turn off; and, depending if your ipod is charge or not, pressing the play/pause button should turn on your ipod on normaly. Hope this helped for being so late.

What causes vertical color lines on ipad2 and how do you remove them ?

What causes vertical color lines on an IPad. And how do you remove them ?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
If still present: Take it to an Apple Store for evaluation.

What causes blank pages appearing suddenly in an autoflowed-text document?

CS5.5, english version.
The complete book was built-up and all master pages were applied . When reopening the file, several blank pages appeared at two places in the document. The text flow was not interrupted, but seamed «hidden» under a non-existing white layer. The software showed «Master page applied», but the pages were blank, imposible to select any object or to place a new text frame. It was also impossible to reapply the master page (the pages were still blank after). We could not access the hidden part of text, even if it was obviously still present, and we had no choice but rebuild a new document.
We don't know what caused this very disturbing bug, and we would avoid it to reappear again! If someone knows a trick, you're welcome!
Version : Indesign CS 5.5, en anglais.
Le livre était monté en entier avec pages maîtresses appliquées. Lors d'une réouverture du fichier, plusieurs pages vides sont apparues, à deux endroits dans le document. Le texte n'était pas interrompu, mais semblait «caché» sous un calque blanc. Le logiciel affichait l'icône de la page maîtresse appliquée, mais la page demeurait vide. Impossible de sélectionner une boîte de texte ni de parvenir à réappliquer la page maîtresse. Nous n'avons pas réussi à accéder à la portion de texte «cachée» sous ces pages vides, bien qu'elle n'ait de toute évidence pas été perdue.
Nous n'avons pas trouvé d'autre solution que de recommencer le montage à zéro à partir d'un nouveau document, mais nous ne savons pas ce qui a causé ce problème, ni comment éviter qu'il survienne à nouveau.
Si quelqu'un a déjà rencontré cette anomalie et peut m'informer, bienvenue!

I'm afraid I don't have any good news for you, though I was able to get the text to reappear by deleting the blank pages and inserting new ones, then rethreading. Youy could do this, but I suspect it is a short-term fix that won't last a day and more important, that output will fail.
ID seems to think the frames on the blank pages are lines with astronomically long lengths and they seem to be sheared as well. Needless to say that seems to be some sort of corruption in the file. The reason that I don't have good news is that I've been completely unable to export anything useful for repair out of the file and reimport it-- neither .idml or tagged text. In all cases I get an error message that the either the file does not exist, it is in use or I don't have permission. I know the files exist -- I can open the text file in a text editor, and I can see the components of the .idml file if I change the extension to .zip, but I can't convince any version of ID to access either of them.
I looked through the file history and noticed that this file began life as a CS4 file that was converted to CS5.5 in August of 2011. I think that's the source of the problem. From time to time we get reports of unexplainable glitches or files that will not output, or just refuse to open at some point, even though they were fine hours earlier, and quite often it turns out that these are legacy files that were directly updated in a newer version. Because of this I now recommend that all legacy files that are to be converted be exported to .inx or .idml from the original version, then that exported file should be opened in the new version.
Actually I had one more thought, and it seems to have been at least partly successful. As I mentioned, I was able to export the main story to InDesign Tagged Text and open that in a text editor (Notepad in this case, since I'm on PC). I tried saving the file from notepad with a new name and lo and behold I can now import it into a new file or use it to replace the text in the original. I tried the replacement, and exporting another .idml. but that still fails to reopen, so the corruption is not in the text of the main story. A .idml file export from a new .indd with the resaved tagged text placed in it also is working.
This means you actually have a good shot at rebuilding this file fairly quickly. Export the stories to tagged text, open those in a plain text editor of your choice and resave as plain text, then place them into a new document with the same page dimensions and margins (rebuild the master pages from scratch in the new file). Make a backup copy of the file with just the text, and make sure it is working properly and that you can export to .idml and PDF, then add the images and check again. I think this is going to work, though it may take a few hours.
DON'T overwrite any of the files you have already -- use new names, and do a save As a the end of each session or at any major change point adding a version number to the name so you have a good backup version chain in case something goes wrong again. Good luck.

What causes banding in Color Gradients?

Using CS6, I created a sky gradient on a new layer, then imported some photos to other layers for a composite. Then I noticed horizontal banding of varying widths in the sky area of the gradient. When I use the Move Tool to move the gradient layer around, the bands move along in a fixed position, so it's not my monitor. When I Option-click on the gradient layer eyeball icon to make just that layer visible, there is no banding on the screen, just a smooth gradient as it should be.
I have never noticed this happening before. What causes it and what can I do about it? Thanks.

Are you absolutely sure it isn't a display issue? I tried to produce banding after an earlier reply, so as to see just what difference I'd see at different bit depths. I change just one channel by one number from foreground to background, and ran gradients right across my 30 inch Dell Ultrasharp, and couldn't see any problems at any bit depth. I didn't try saving out to JPG and reloading, or reducing the file to Indexed colour to lower bit depth still further, but I was reasonably sure that I would see a problem after doing so.

I seriously don't know what caused this to start being a problem until today it worked fine, but I added an exception for popups full question in DETAILS

is there anyway to allow Firefox to allow pop ups from this 1 page of Facebook / well this 1 game https://apps.facebook.com/vampiresdarkside/ and not the entire pan in the Ass Pop up happy site, I cant see any sense in allowing popups from all
apps.facebook.com
and when I try to add it as the exception should be your program edits it to be that crap above instead of the exception I entered specifically,
apps.facebook.com/vampiresdarkside/
I seriously don't know what caused this to start being a problem until today it worked fine, but I added an exception for popups from this one site in Chrome and Firefox decided it wouldn't allow it popups from this part of Facebook and no I am not allowing all the FB apps to have popups I never had to before
apps.facebook.com/vampiresdarkside/
have popups after adding the popup exception in chrome, and no I did nothing to Firefox but it is kinda asking me to switch to Opera or some other crap browser with it acting like this, I modified the exception in chrome and Firefox now wont allow the pop ups it always had up until chrome allowed them WTF

Tools for root cause analysis of stack corruption?

I'm experiencing extremely rare stack corruption that results in SEGV core dumps for a large and complex C++ program. Having run all the standard tools such as IBM Rational Purify, Sun mdb/libumem and dbx/rtc (although unfortunately using dbx check -access takes inordinately long and eventually crashes before the main() function is executed), I am no closer to discovering the root cause of the stack corruption. I'm confident based on the tools run and on the stack trace from the core dump that the problem is not heap corruption, but stack corruption.
The environment is Sun Studio 12 (but not update 1) on Solaris 10 on SPARC. The program is compiled with minor optimisation (-xO2 -xbuiltin=%all).
Is anyone aware of other tools or approaches that could help pinpoint the problem? Your help would be much appreciated!
Thanks in advance,
Simon

If you are in fact having stack corruption issues, I don't think any of the tools you mentioned other than Purify would help you identify it.
You may also be simply running out of stack space, and not having corruption issues. Is your app multi-threaded? If so, you could increase the stack size your threads use to something larger than the default.
Another thing you can look for are syslog entries stating "no swap space to grow stack" for your process, you've run out of virtual memory. To avoid this, you can "pre-allocate" your stack memory with code similar to this:
void growStack( size_t bytes )
    char *mem = ( char * ) alloca( bytes );
    memset( mem, 0, bytes );
    return;
}That code, when called, will force the creation of stack memory virtual pages backed by swap, before your server gets into a situation where free memory might be in short supply.
I also seem to recall that Solaris under certain circumstances will allocate stack memory with the MAP_NORESERVE option, which means swap space won't be reserved for your stack. If your process gets swapped out, its stack(s) will be lost and you'll probably get a SIGSEGV or SIGBUS. See this bug:
[http://bugs.opensolaris.org/view_bug.do?bug_id=1221729|http://bugs.opensolaris.org/view_bug.do?bug_id=1221729]
I remember working a similar issue for a customer running large apps on Sun E15Ks, maybe about 5 years ago. To work around this behavoir, I think you'll need to explicitly allocate stack memory for any threads you may be creating. I think that's what we had to do.

What causes cellular data usage to decrease if last reset has not changed? I reset every pay period cuz I do not have unlimited and was showing 125 mb sent/1.2g received. Now showing 98mb sent/980mb received. Last reset still shows same

I reset my cellular data usage every month at the beginning of my billing period so that I can keep track of how much data I am using thru out the month. I do not have the unlimited data plan and have gone over a few times. It's usually the last couple days of my billing cycle and I am charged $10 for an extra gig which I barely use 10% of before my usage is restarted for new billing cycle. FYI, they do not carry the remainder of the unused gig that you purchase for $10 which I disagree with. But have accepted. Lol Moving on.
I have two questions. One possibly being answered by the other. 1. Is cellular data used when I sync to iTunes on my home computer to load songs onto my iPhone from my iTunes library(songs that already exist)? 2. What causes the cellular data usage readings in iPhone settings/general/usage/cellular usage to decrease if my last reset has not changed? It is close to end of my billing cycle and I have been keeping close eye. Earlier today it read around 180mb sent/1.2gb received. Now it reads 90mb sent/980 mb recieved. My last reset date reads the same as before. I don't know if my sync and music management had anything to do with the decrease but i didn't notice the decrease until after I had connected to iTunes and loaded music. I should also mention that a 700mb app automatically loaded itself to my phone during the sync process. Is cellular data used at all during any kind of sync /iPhone/iTunes management? Is the cellular data usage reading under iPhone settings a reliable source to keep track of monthly data usage? Guess turned out to be more than two questions but all related. Thanks in advance for any help you can offer me. It is information I find valuable. Sorry for the book long question.

Is cellular data used at all during any kind of sync /iPhone/iTunes management? Is the cellular data usage reading under iPhone settings a reliable source to keep track of monthly data usage?
1) No.
2) It does provide an estimated usage, but it's not accurate. For accurate determination, you should check the remaining/used MBs from the carrier (most of the carriers provide this service for free).

What causes a slow mouse/cursor response on a fast machine?

I have a system that has always displayed poor cursor redraw performance with certain adobe applications. All rendering and other effects are fast, but basic mouse selections and button knobs are extremely unresponsive. I have searched and searched and can not seem to find out what causes the mouse cursor speed issues. Does anyone have any ideas as to why my mouse would slow for such basic Interface interactions? Do I need to change my hardware, settings, displays, BIOS, etc?
Any insight into what the mouse redraw/refresh is called in terms of computing would help me search for a solution. And if you have a solution as to why my mouse cursor acts drunk and sluggish when interacting with the Adobe UI's in premiere and after effects and sometimes Photoshop I would greatly appreciate the help.
Thank You. I attached a screen shot of a very basic selection interaction that is dog slow. The selection box redraws like there is a lag in some process associated with the square box overlay.
