Any appraoch to make update fast

I am using Oralce 10g on Solaris 10.
I have a table Gprcval that contains about 200 million rows.
I am to update this table daily.
The update comes in a file which normally contains more than 1 million rows.
Table data is updated based on Flags column in the file e.g. I stands for insert, U for update etc.
I want to know the best approach to update the table.
Currently, i simply load data using sqlloader into some intermediate table and then by making joins, i perform DML operations on my original table. But that process is not much fast. It takes about 11-12 mins for a file having 100 thousand rows.
I used then partitioned table approach. But that does not produce significant result.
Is there any other approach in Oracle that could benefit me?

have you tried dropping the indexes and running the
insert/updates and then rebuilding them because if
there are indexes on a huge tbale and if you perform
dml activity then it is advisable to drop the indexes
and then do it....Well that's two full scans of a huge table guaranteed then. It wouldn't be my first choice.

How to make Mavericks faster on an "older" MacBook Pro?

I have a late 2011 MacBook Pro, 2.2 GHz core i7 with 4 GB of RAM. I recently wiped my computer and restored to factory settings because it was getting slow, then I upgraded to Mavericks and it is even slower. It freezes often and takes a long time to load things. Is there any way to make it faster or improve it's function?

Oh wow, I must be REALLY out of it, haha, don't know how I missed that.

After updating my ios4 to ios 6.1, it became very slow. Browsing my music takes forever. How do i fix it to make it fast again without losing my music files?

After updating my ipod touch 4th gen ios 4.1 to ios 6.1.6, browsing my music files became super slow..I lost all my music files and was even forced to download new ones..But im not happy with maneuvering my music files after the update as it takes really slow to move from one playlist to another..I wish I could downgrade it to my original ios 4 as it was much faster then in maneuvering music files. Or is there a way for me to make it faster???Im only using my ipod touch 4th gen for listening to my music files and nothing more. I also noticed that whenever I dock my ipod touch to my Bose sound Dock, the remote control only function on its volume controls but not the skip buttons. i sent my Bose dock to Bose service center and told me that my Bose dock system is working fine but not my Ipod touch 4th gen.. Pls help me...

- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Unsync/delete all music and resync
To delete all music go to Settings>General>Usage>Storage>Music>Tap edit in upper right and then tap the minus sign by All Music
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: Back up and restore your iOS device with iCloud or iTunes
- Restore to factory settings/new iOS device.
Also, go to Bose's support site, they may have suggestions for that problem

Iphone 4S newly updated to iOS8, keeps popping up window notifying me of things I turned off (cell usage, location, etc) to preserve battery life. Is there any way to make them stop telling me every time I use the affected apps?

I have finally taken the step of updating my iPhone 4S to iOS8 after learning the hard way last update to wait for the bugs to be worked out. I was horrified to find that the battery was being sucked dry in no time at all. After finding a great article posted elsewhere on the apple forums, I went through and turned off all unnecessary options involving the use of cell data, location services and background refreshing. My battery life has thankfully returned to what it was before the update.
HOWEVER, now, every time I open an app for which I turned these things off, the window informing me of that pops up.   I am getting really irritated by this as I made all of these decisions deliberately and am well aware that I may need to go back and change them in order to activate certain capabilities when I want to use them. I had done the same thing with the last iOS, but there were far fewer that needed to be turned off and the battery life seemed to be less affected by those that I left on so it was not the annoyance it has become now.
Is there any way to make the phone stop presenting me with these idiot messages?   TIA

Sorry no, there isn't a way to turn off those reminders.

I am trying to update my Ipad 1 but it is taking hours on the backup, what can I do to make this faster?

I'm thinking that you have a corrupt backup. You can try this if you want to give it a shot.
Without connecting the iPad to the computer, launch iTunes. Go to Edit>Preferences>Devices. See how many backups you have for the iPad. If you have multiple backups, delete all but one. Click on the backup in the window and then click on Delete.
Quit iTunes, connect the iPad and then try again.

My macbook pro 2006 fan goes high and then makes a fast beep and shuts down it been happening since i updated

my macbook pro 2006 fan goes high and then makes a fast beep and shuts down it been happening since i updated it should i update to lion?

No, this problem should be solved.
The MBP shuts down when too hot, to protect itself. First see if it is a process running astray: start Activity Monitor (in Applications/Utilities) choose <all processes> and click the %CPU column: are there processes that are using more than 50% cpu power? If yes click it and quit it, and tell us which one.

I have a iMac desktop and a macbook pro laptop I work mainly on the desktop but when i go away for work I take my laptop. Is there any way to make it automatically back up to mirror my desktop? Like when I update a file it updates on there too etc?

I have a iMac desktop and a macbook pro laptop I work mainly on the desktop but when i go away for work I take my laptop. Is there any way to make it automatically back up to mirror my desktop? Like when I update a file it updates on there too, if I install software it installs on there too etc?
When I first got the laptop I syned it to load with all the same software etc but it hasn't continued to sync
Thanks

I use
Chronosync (http://www.econtechnologies.com/pages/cs/chrono_overview.html)
and
Dropbox (https://www.dropbox.com/)
Both work very well. The former I use for manual, one-way synchroniziation of (nearly) entire systems. The latter for automatic syncing of very active directories through local and shared online storage.

Painfully slow startup - any suggestions how to make it faster?

Hi Everyone,
Just thought I'd ask people - my 17" iMac G5 1.9GHz PowerPC with 512MB ram is painfully slow at start-up. Seems to take forever! Does anyone know how I could clear a lot of rubbish from my computer and someone make it faster.
Would anyone recommend a complete re-install - would that improve speed?
Any help appreciated, cheers,
Mark

Mark, you can clear space on your drive and speed it up by moving a lot of sound and video files to a DVD, or even better, to an external; Firewire drive that you can partition and also use as a clone boot disk.
Go through your applications folder and look for stuff that you never use, then get AppZapper to remove all traces of them. You can also use Monolingual to remove the tons of extra languages installed with Word and OS X, just make sure you uncheck English and any other language you might use.
Hope some of this helps,
Miriam

Periodically delete all apps from the recently-used bar (double clickHome button) and power off and then back on the iPod. With iOS 5, the iPod uses more memory (do not confuse with storage) and periodically you have to reclaim memory for use.

I can't update any apps or make any purchases. Someone help because iOS7 is horrible ATM....

My ipad won't download any apps or make any purchases. Someone help because this is ridiculously stupid. If any Apple people see this then tell the company to patch this because this is extremely annoying, especially with post-halloween updates and new music coming out.

Log out of the iTunes Store on your device:
Settings>iTunes & App Store...tap your Apple ID, then select "Sign Out"
Reset your device:
Device Reset (won't affect settings/data/music/apps/etc)
1. Press and hold (& continue to hold) BOTH the Sleep/Wake button & the Home button.
2. Continue to hold BOTH (ignoring any other messages that may show) until you see the Apple logo on the screen.
3. Release BOTH buttons when you see the Apple logo and allow the device to boot normally.
After the device has restarted, sign back in to the App Store as above. Try to download the apps again.

Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
