1 million row full table scan in less than one minute?

All,
a customer has a table which is around 1 million rows.
The table size is 300 Mo.
The customer wants to calculate regular arithmetic operations,
and synthetic data on the whole table. He will use 'group by'
statements and 'sort by'.
He wants to know if it would be possible to get the results in
less than one minute, and what would be the necessary
architecture in order to achieve this?
He currently has a 4 Gb Ram machine, 4 processors (I think...).
It's a 7.3 database.
Would an upgrade to 8i or 9i help? Would partitioning help?
Would parallel query help? What else?
There will be no other concurrent requests on the system.
Thanks!

Hi
If you have four processors parallel query will increase speed
of executing your statement. It will work better with
partitions. In version 7.3 is not very easy to manage partitons
because you have not partition tables - you have only partition
views. Maybe the speed is the same but management of partition
views is not so easy. So in version 8i and 9i it will be better.
If you have index for group by columns and they are 'NOT NULL'
it will be additional way of increasing speed beacause you will
eleminate sort operation.
Regards

  • Time Machine Migration hanging on "Less than one minute remaining"

    I decided to take a risk with my iMac and do an erase and install with Leopard, the version of OS X it's been running for years now. The reinstall went fine migration assistent got me started transferring my information from my Time Machine external USB 2.0 hard drive. It said it was just over 200 GB of information. That proceeded fine until it reached the "Less than one minute remaining" mark. It's been sitting here for over 12 hours in the "transferring files to support applications" process. What should I do? Is it alright for me to manually turn off the computer and re-boot? There is no cancel button or anything. I do get the pleasant clunking sound when I hit enter.

    Welcome to Apple Support Communities
    If you have connected both computers with a cable, disconnect and connect that cable again, so migration should continue. If it doesn't work, restart your MacBook Pro and check that all the files have been transferred. If not, open Migration Assistant and transfer your files

  • Just tried installing an update to OS.  Although the screen tells me that the installation will be completed in less than one minute, that was two hours ago, and the computer won't permit me to shut it down via the power button, as I get an error sound.

    Just tried installing an update to OSX Snow Leopard.  Prior to trying to update OS, I was running V 10.6.3.  During installation, it locked up.  Although the screen tells me that the installation will be completed in less than one minute, that was two hours ago, and the computer won't permit me to shut it down via the power button, as I get an error sound.  What do I do now?  Help!

    Hold the power key till it shuts down, it may take a little while, try holding it thru the warning.
    Then if it shuts down restart and open Safari/Preferences, General tab, and set "Save Downloaded Files to:"
    Select desktop, if desktop is not available in the the drop down menu, click other, then select Desktop from the column from the on the left.
    Then download this:

    Click on the installer pkg and follow the prompts.
    Hope this helps

    try this
    Reboot device by pressing both the home button and sleep/wake (power) buttons at the same time for 10-15 seconds until the apple logo appears on the screen, then let go.
    if that doesn't work then connect to a computer and try to open the device in itunes

  • Latest update 7.1.2 stuck with less than one minute remaining

    I Couldn't download anymore apps and noticed I needed to update my software to the latest version so thought that this would solve the problem. I started the update at 11pm last night and after waiting 2 hours with it on  charge and connected to wifi it still said less than one minute remaining.  Searches on internet suggest a hard reboot but will this loose my apps as some I have are no longer available to get?  I have backed up photos etc to the cloud so not too worried about those.
    any advise please   Thanks in advance

    With an iOS device, the “Other” space in iTunes is used to store things like documents, settings, caches, and a few other important items. If you sync lots of documents to apps like GoodReader, DropCopy, or anything else that reads external files, your storage use can skyrocket. With iOS 5/6/7, you can see exactly which applications are taking up the most space. Just head to Settings > General > Usage, and tap the button labeled Show All Apps. The storage section will show you the app and how much storage space it is taking up. Tap on the app name to get a description of the additional storage space being used by the app’s documents and data. You can remove the storage-hogging application and all of its data directly from this screen, or manually remove the data by opening the app. Some applications, especially those designed by Apple, will allow you to remove stored data by swiping from left to right on the item to reveal a Delete button.

  • HT204350 my migration was stuck for hours while it was in the "remaining less than one minute" phase of the mirgration complete

    I was using the migration assist from an imac to a macbook air both running the latest versions of mavericks.
    The migration strated and bioth computers were on the even count down. At the point when it stated less than one minute to completing the migration assist it just remained like that for over 12 hours.
    i had to reboot one of the machines to be able to reset it. Nothing was migrated when restarted the machines.
    Any ideas why this happened and what can be done to make sure it doesnt happen again?
    I was migrating my system applications only.

    just had a look on the apple store. Have found a converter. Will try this. Hopefully will work.
    Thanks for your contribution to this community

  • Migrating assistant freezes at less than one minute remaining os x lion

    Hi I recently got a macbook pro 13" os x lion, i5 2.4Hz. And i'm using migrating assistant to move my files over from a pc (45gb). The process was fine until it reaches nearly the end where it says cleaning up "less than a minute remaining" and it has been stuck there for ages. My laptop which is the source computer for some reason turned off by itself when it gets to the end of the process. I didnt know how it happened because i was unattened. However the mac was still running. Is it normal? Should i wait or start over again?

  • Installation stuck now for four hours at "less than one minute remaining"

    I've seen this occasionally, but using a full OS X installer, I've now been stuck at the<1 minute mark for several hours. I'm going to give it through the night, but I've often not seen this resolve. Should I continue?

    Press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly to restart.

  • IMac starting and shuts down after less than one minute...

    Hi !
    I hope someone could help me with this problem...
    I think I've tried everything... CMD+Alt+P+R / CMD+R / ... SMC...
    I'm a little lost because I can't access to the computer (it shuts down before arriving on the desktop). I've also tried to access just to the hard drive by connecting 2 Mac with Firewire cable... And the same problem appears. The iMac is also shutting down to soon to backup anything...
    Is there someone who has experienced the same problem ?
    Thanks !
    Best regards,

  • Full table scans and EUL

    Hi All,
    I am using Discoverer Version 10.1.2.1.
    I have few reports in which tables used in queries (used in Custom folders) go into full table scans inspite of all efforts in tuning.
    I came to know that full table scans also come from the way EUL is built and maintained.
    Can anyone please throw some light on how does EUL and full table scan relate.
    Also one more thing here, which is better to use, Database View on which we can base our folder or writing the complete complex query in the folder.
    Any help in this case will be appreciated.
    Regards,
    Ankur

    Hi,
    Can anyone please throw some light on how does EUL and full table scan relateThe database cost base optimiser processes the SQL that has been generated by Discoverer and creates an execution plan for the SQL. Now the execution plan will contain full table scans if the CBO calculates that FTS will give the best results. The CBO mainly uses the statistics held against the tables and the conditions in the SQL to calculate whether FTS would be better than using an index. The table join conditions are usually defined in the EUL but other conditions are usually in the workbook.
    So there are many factors which control whether the database uses an FTS and only a few of them are affected by how the EUL is built.
    Database View on which we can base our folder or writing the complete complex query in the folderIn general, it is always better to create a database view if that option is available to you. You can control and monitor the SQL in a database view much more easily than using a query in a custom folder.

  • HELP! LOCKED IN LIMBO W/MIGRATION ASSISTANT DATA TRANSFER:  "LESS THAN 1 MINUTE LEFT" FOR 10 HOURS

    This has happened before. I'm migrating from one Macbook Pro to another Mac (though it doesn't seem to matter if it's a MBP or other Apple powerbook) and it gets almost to the end of the bar with the blue water line a sliver away from finishing but it stays at "less than one minute remaining" as it finishes up migrating settings. Going on 10 hours now.
    Have read other discussions from 2009 to earlier this month w/this issue.Some say it's a Lion OS issue that's been acknowledged as a flaw. Others had the same issue w/Leopard & say to ignore the remaining minute & leave it alone until it finishes which could take a day or more. I'm moving almost 300 GB of data. I've done this before and had same issue and interrupted it. I manually migrated over applications, documents, etc, one by one and it still took overnight just to do some of the data, so this is  not an inordinate amount of time.
    If it's going to complete, I'll let it run. If it's not, I'd like to know so I don't waste more time trying... Thanks in advance for assistance w/this conundrum.

    I'm not a big fan of migration assistant, because this happens all the time.  I'd give it a few more hours, then say "I give up."
    Why didn't you use the Setup Assistant on the target mac using the firewire disk mode?  I don't have absolute evidence, but you rarely see issues with people who use the Setup Assistant with a newly installed OSX (or brand new Mac). 

  • If you migration hangs at "less than a minute remaining," maybe ok still

    I just wanted to describe my experience using the Migration Assistant app with my new 15" MacBook Pro i7 model.
    I had a Core2Duo MacBook (black casing) with about 185GB of data on it. I setup the Migration Assistant process to import the data to my new Macbook Pro, after about 4 hours of importing it hung at the 10 minute remaining point telling me to check my connection (ethernet) for problems. I changed out the ethernet cable and had to click "continue" about 3 times before it started working again.
    Then at the "less than one minute remaining" point, which was an hour of waiting for me, I called Apple Support and basically we determined it wasn't going to move and just canceled and rebooted.
    At first it appeared nothing transferred to the MacBook Pro because I was greeted with the choose language prompts upon first rebooting. However, just go through those as normal, choose NOT to import any data then go to the desktop (you may still have to create a dummy login account) then go to Accounts and choose the one you migrated which hopefully is there, then just delete the dummy account.
    Glad I realized this before going through another 4+ hour migration!
    Hope this can help someone if it happens to them.

    I ran into something similar yesterday while running Migration Assistant.
    I solved this riddle myself by turning off the WiFi on both computers. For some reason, with an ethernet connection checked, the Migration Assistant still chose to transfer my data via WiFi with quickest time estimate of over 24 hours.
    The only other time I did this with Migration Assistant, it apparently used the ethernet cabling right from the start.
    This latest attempt is only going to take about 2 hours. As to why Migration would choose wifi when there was a valid ethernet connection available, I'll leave that to the experts. With AirPort turned off, I transfered about 120GB of data in slightly less than 2 hours.
