Tunning required

Hi
I have created more than 15 packages for a single application
i have used many procedures functions on no:of tables.
after running the project they have taking long longtime.
what is best way to tune the plsql query's
and please explain how to tune the query's with an example..
i am very thankfull ... in advance

Have you been gathering stats as you've been coding individual procedures/pakages or did you save it all for last? As others have said, you'll need A LOT more to get any help. Is it a process running slow? Is it one procedure running slow? Is it one query in a stored procedure? If your current stuff is slow, what is considered acceptable? And so on...
If you don't have any metrics at all, it might be helpful to write a package that dumps descriptions & timestamps to a table. Then you put calls to the package at the start/end of your procedures, and any other points you want to capture run-times for. Then you can calculate where most of your time is spent while processing, and tune where needed.

Hi Markynewman,
If you're unable to sync with iTunes any more and the error states you need a newer version of Apple Mobile Device Support, I would check out this article:
iOS: Device not recognized in iTunes for Windows
http://support.apple.com/kb/TS1538
The first section has you troubleshoot your device, which is always a good idea but you might be able to skip since the error mentions Apple Mobile Device Support as the culprit. The second section is for troubleshooting iTunes and Apple Mobile Device Support.

Tunning Required! One more one for the Challengers!

Hi all,
This is one more to challenge!
SELECT COUNT(1) FROM WHSE_LOC WHERE ((AREA_C,WKSTN_C) IN (SELECT AREA_C, WKSTN_C FROM WHSE_LOC WHERE AISLE_I = :B3 AND BIN_I = :B2 AND LVL_I = :B1 ) ) AND (AISLE_I,BIN_I,LVL_I) NOT IN (SELECT AISLE_I, BIN_I, LVL_I FROM WHSE_LOC WHERE AISLE_I = :B3 AND BIN_I = :B2 AND LVL_I = :B1 );
I have the above query in one among the packages. My DBA reports that this query is the longest running in our database from : 7.22PM to 8.15PM IST.
The record size currently is around 38500. This works when the records size is less than 5000 but when gone beyond that this fails. Can anybody help in this reg.?
The following is the description of the table:

You are accessing the table three times, and you can reduce that to one:

for reasons unknown my usual synch process wouldnt work and not only had i to restore factory settings but then i tunes required me to reset my password but i retained my apple id. most items were restored when the phone was synchronised but my purchased apps were not.
have tried calling apple support but very difficult to get through

This indicates corrupt files.
Restore as new.

Can't open I Tunes

Hello ))) I just bought a secondhand Macbook air 2009 edition. I spent one day to update it and now seems that everything is ok and update.
I also downloaded and installed the latest Itunes version. But when I try to open Itunes it doesn't and an alert message says: " I tunes requires Quick Time 7.5.5 version or later".
So downloaded Quicktime.exe and launch this file, but doesn't start any installing but I can see only a strange Dos window.
What can i do?
thanks

Pinnacle USB Pro Stick Tuner and FIOS

I have a pinnacle pro stick usb. It supports clearqam and when I scan, it only give me local hd channels as well as music channel. It doesn't pick up discovery hd etc.. What am i doing wrong here?
I scanned analog/digital and digital clearqam.
Any help much appreciated.

So those TV tuners work either for 'Antenna based HD channels' or via a FIOS set top box. What a shame cable company forces you to get a box.
Yes, those "Clear QAM" tuners can only record local HD channels. But the cable company does not force you get their own box.
With FiOS and other cable providers, you are permitted to buy your own TivoHD or Moxi CableCard DVR. You can also buy or build a PC that supports CableCards. When equipped with a $3.99/mo CableCard, all of these solutions allow you to tune and record all FiOS SD and HD channels. They do cost more than your typical $100 "Clear QAM" tuner card that does not have the necessary technology to support encrypted channels.
It costs about $800 to build a new computer with two CableCard tuners. Each ATI CableCard tuner costs about $200 and special motherboard with CableCard support is required. Each ATI CableCard tuner requires a separate $3.99/mo CableCard from Verizon. PCs aren't able to support multiple tuners with a single card like TiVo and Moxi.

Please note - this was not a personalized email - Apple is sending this out to ALL podcasts that are listed on iTunes.
If you are hosting with Libsyn or most any other "Podcast" host you should be ok.

If you are on a self hosted site or worse yet using some file storage service like Dropbox - then you are going to have issues.
Again - this leter from Apple does not mean anything is wrong wth your show specifically - it is a generic letter going out to all podcasters.

Please re-install i-tunes

When trying to log onto i-tunes i get this message!
"Quick time version 6.5 is installed, i-tunes requires version 7.1.3 or later.
Please re-instal i-tunes"
I have downloaded both version 7.1.3 and the latest version of i-tunes but not progressing any further.
Any ideas?
JK

"Quick time version 6.5 is installed, i-tunes requires version 7.1.3 or later.
Please re-instal i-tunes"
did this start happening out of the blue? (in other words, you had a perfectly functional itunes, and then suddenly it starts claiming that QT version 6.5 is installed?)
if so, by any chance did you install a K-Lite or ACE Mega Codec Pack on that PC just before this started happening? if so, which version?

G4 400MHz OS 10.2 update to 10.2.8 won't work

I have tried to update from the software updater and the website download. Both times it stops and says a problem was encountered, but it does not tell me what the problem is. My I tunes requires an OS of 10.2.8 or better. What can I do? Should I spend the $ on 10.3 or later? I worry that the model will not work well with it. Thanks for any insight you can offer. Hart

Welcome to Apple Discussions.
Some people have difficulty upgrading directly to 10.2.8 and need to do it in stages going first to Mac OS X 10.2.4 Update (Combo), then to Mac OS X 10.2.6 Update Combo and finally to Mac OS X Update Combo 10.2.8. Here is Mac OS X 10.2: Chart of available Mac OS software updates.

2. Every image which is tranfered over SSGD Behaves as a bitmap image . Which take time to load and the changes also transfer very slow.
Can any body guide me on this ?

I've seen various products that permit one to load music files onto a hard drive component linked to the stereo and even link to TV screens to control song selection, etc. None that I can find will play any songs purchased from iTunes. My house is set up in a way that does not easily permit plugging my iPod directly into the stereo and Air Tunes requires me to be at my computer to control song selection, etc. I just want remote access to song files (my house is fully wired) but don't want to give up all the iTunes music I've purchased. What am I missing? Is there a solution? Thanks in advance.

Error 1714. The older version of QuickTime cannot be removed. - Fix

I ran into this problem when I was installing the latest version of i-Tunes. Because i-Tunes requires QuickTime I researched for hours. I couldn't un-install QuickTime, it wasn't showing up in a software list to uninstall. I used Regedit to remove all of the "QuickTime" entries in the registry. Restarted my computer, still no luck.
One thing that I did I ran the Quickertime installer from a DOS prompt and added /le file.txt
This creates a log file with all the error during the installation.
This gave me the follow error in the file:
=== Logging started: 12/30/2006 17:29:18 ===
Error 1714. The older version of QuickTime cannot be removed. Contact your technical support group. System Error 1610.
=== Logging stopped: 12/30/2006 17:29:31 ===
Again this is what I to searched for the errors with on luck.
I ran the Quicktime installer again, this time I used the /l* file2.txt. This logs everything during the installation.
I searched this file for where the errors were and found this:
RemoveExistingProducts: Application: {50D8FFDD-90CD-4859-841F-AA1961C7767A}, Command line: UPGRADINGPRODUCTCODE={F07B861C-72B9-40A4-8B1A-AAED4C06A7E8} REMOVE=ALL

Error 1714. The older version of QuickTime cannot be removed. Contact your technical support group. System Error 1610.
MSI (s) (88:08) [18:39:07:734]: Product: QuickTime -- Error 1714. The older version of QuickTime cannot be removed. Contact your technical support group. System Error 1610.
Then in the registry removed the entry 50D8FFDD-90CD-4859-841F-AA1961C7767A in the HKLM\Software\Classes\Installer\Products directory.
!!!!Make a backup of your registry if you are unfamiliar with regedit.

Thank you so much for this solution! I spent hours trying to figure it out myself and by following your steps I got it working! My numbers were different but I was able to figure out which one I needed to delete. Thank you once again!

Ipad locked,passcode unknown,need to restore

IPAD is locked, wrong passcode entered too many times. Need complete restore, connected to I Tunes, however I Tunes requires PassCode to continue. Any ideas?

Try and force your iPad into Recovery Mode:
1. Turn off iPad
2. Connect USB cable to computer; leave the other end alone
3. Press and hold the Home button down and connect the docking end of cable to iPad
4. Continue holding the Home button until you see the "Connect To iTune" screen
5. Release the Home button
6. Open iTune
7. You should see "iTunes has detected an iPad in recovery mode"
8. Use iTune to restore iPad
Note: You need to be patient and repeat the above many times to recover your iPad

Tunning required
