Exadata redo

Hi, I need advice here.

I created data bases on our x 3 full rac environment.  Version of DB is 11204.

I did an exachk, and it displays this warning:

Database machine provides again extremely high rates of generation that you plan to increase the size of the log files. After the initial deployment, the size of the logs online should be 4 GB each.

My current size of the redo log is 1 g, old non-exadata rac environment redo log size is 500 m.

This environment has enormous data and lots of OLTP more query, so it's sort of a mix environment.

How can be sure that the size of redo log is optimal and where I place the redo logs? What type of discs? Flash drive or regular disks?

Thanks in advance.

Based on your current redo 1500 MB of use is fine.

That being said, I don't think not having 4 GB newspapers adversely affect performance either, so maybe that's why the exachk threshold is a bit on the side high.

  • Undo/Redo disabled

    I could really use some help.  Out of nowhere my command-z has stopped working.  It turns out that, undo/redo are both disabled.  I have come other forums for the answer, but have received no solution.   Of course these rather random and stupid things always happen when an important deadline looms.

    Can anyone help?  Using OSX v10.11.6 and I work on a Mac Pro with a 3.7 GHz Quad Core with 64 GB of memory with a lot of storage space on all my drives.  I work with external systems for storage and production of projects/libraries and keep my own house with plenty of space empty.

  • Aspire V13 V3 - 372T can I redo initial set upward?

    Hello

    I recently bought Acer Aspire V13 V3 - 372T with 10 Windows installed, but my brother has opened in front of me, crossed the initial installation and installed a few things for me (nobody said he should or is allowed to do, on the contrary) and now I don't know what he has selected in the implementation. Of course, he remembers nothing.

    Is there a way I can redo the installation without uninstalling Windows 10? I don't care if what he installed gets uninstalled in the process.

    Thanks in advance.

    Hello, I'm just "passing" in a manner of speaking, and it really depends on the extent of your problem.  As there is no way to make the configuration that I know, there are a few options that allows you to undo the changes he made.     If it has installed software shaded an unknown source or something like that, then I would recommend a refresh or a reboot of the system, because it may contain a virus.  Both include reinstalling Windows, but they are relatively easy and should only take a 1-3 hours after my experience, especially because you have a fast computer (I own one).  An update is easier and probably easier to apply in your case, because it uninstalls all programs and resets all settings (don't quote me on that one).  But if it comes from certain programs installed and changed a few settings, then you can simply create a new account and delete the old.  Which allows to uninstall all applications in store Windows and you can choose your settings again.

    Directionsfor create a new account to crush the former: right click the button start - Control Panel - user accounts - user accounts - manage another account - you will be invited to authorize, hit Yes - add account - Local account or Microsoft Account make your choice (I could write a whole article about it, but for now, I advise to use a local account for the moment (you can change it later) - click on the account you just created account type) and the value to the administrator.  Delete the old, then tap on delete account. Once you have done all the settings will return to its original state, all user installed (non-conventional programs like Google Chrome) applications are uninstalled.  If you need a list of all the programs installed on the computer just ask.  But I could have bought my computer somewhere else it can be different.

    Directions for resetting Windows (latest version with update of the anniversary (it is probably not very different in old windows 10 is)): reinstalls the operating system and replace the hard drive.  Start - Settings - updates and security - recovery - restart now, then you should see an option with reset wrote under the title.  Follow it until you see a screen that has a button to recycle your PC.  If you do not just take a picture of it and send it to me.

    Directionsfor discount Windows: even just instead of hitting recycle, hit keep my files (or something of the sort)

  • Activation of Aero without redoing the entire theme

    Years ago I switched on the 'Windows' classic theme, then customized a lot of things.

    Now, I think I would try to activate Aero again because I don't remember why I disabled it other that something bothered me.

    However, the only way I found via search to do this is to change the entire theme by clicking on one of the "Aero Themes", which resets all my fonts and other settings. I can get it by clicking on my custom theme.

    Is there another way to activate the effects Aero Glass without changing everything as my tweaks to the font sizes on used in various things, my selection of wallpapers, custom, sounds that I attributed, colors of window, etc.?

    All the things that I get by searching say goto customize and choose the theme Aero in Windows 7. Either that, or use the Troubleshoot utility that also resets the theme.

    In XP, all the effects could be adjusted individually, they were not a packaged deal. How to activate Aero without spending at least an hour redoing my semi-custom theme?

  • Microsoft Natural 4000 ergonomic keyboard with IntelliType 8.15 64-bit for Windows 7, some keys are not function (new, open, undo, redo, fence, etc.) in Office 2010

    Hello MSFT sensi.
    I need help. I have the Microsoft Natural ergonomic 4000 keyboard with IntelliType 8.15 64-bit for Windows 7 installed. I run on a brand new i7 with 9 GB of ram and 1 TB of hard drive.  I just installed Office 2010.  Have you tested this keayboard with Office 2010?

    I bought and returned 2 of these keyboards at my local dealer and two keyboards have the same problem. Preconfigured keys (help, undo, redo, new, open, close, reply, fwd, send, spell, save and print) F1 - F12 do function not all as they are indicated in MS Word 2010 etc. I was able to program my favorites 1-5 with little problem.

    I did the following to try to resolve the problem:
    1. research of virus (clean)
    2. uninstalled the driver and downloaded the last strand 8.15 64
    3 entered the keyboard layout configuration and reset the default settings
    4 tried to manually program the F1 - F12 function keys

    NONE of these things solve the problem.  Which brings me to the conclusion that this keyboard does not have to be 100% compatible with Office 2010.

    Any suggestions / feature of configuration problems feature keys?

    PS. No, I didn't record this keyboard, because is it not there no solution - he goes back to the retailer.

    To the right of the function keys, there is a key LOCK.

    Toggle this button to toggle between the keys F1 to F12 with their usual function and the functions listed in the relevant programs.

  • ORACLE: Redo wait

    Hi all

    on 5.6.4 we receive foglight alarm:

    ORACLE: Wait for Redo: criticism

    The instance has spent the 29, 30 sec of its activity on again wait, which is significantly higher than the observed typical behavior for this period (

    until 24,69 sec).

    I have a few questions:

    -J' looked at Oracle alertlog and lgwr trace for alarm period but file I saw nothing of Oracle in them. How/where to check if Oracle warned on this subject?

    -Is a problem writing in newspapers of recovery or a problem of redo buffer?

    Thanks for the help.

    I do not think that oracle could write anything in the alert for writing redo log is slow.  Since it is a deviation from normal alarm, you can watch the activity at this time and also waiting for disk queuing (response of the disk write time) during this period.  It's maybe just a case where you have more activity than usual update/insert causing higher than usual waiting for recovery.  Or you can have disk contention where residence your recovery logs.

  • When doing an insert, which undo and redo do

    as it is said

    When you insert a row, or perform any other DML, Oracle will write information in the Undo tablespace that can be used to cancel the operation. If the user issues "rollback" or there is another reason does not commit the transaction, Oracle is going to undo the change, where the name. Roll forward is a recovery mechanism that allows to replay transactions. The redo records do what they say, they have left Oracle recreate or redo the transaction. Undo and redo go hand in hand. Indeed, Oracle writes both the cancellation and the restore information by progress in online redo logs.

    I recommend reading the Guide of the Concepts for more information.

    See you soon,.

    Is it a sign of botteneck? Users complained that each 15:00 they encounter performance degradation.

    If your users are complaining about slow at 15:00 then look at what is happening on the system at this point in time.  Use the Active Session history, providing that you have the license, at 3 pm to see if there is a problem.  Or take snapshots of the AWR manually around 15:00 in an attempt to capture any anomaly.  Or capture instant V$ SESSION yourself manually around 15:00 and see so many sessions is pending or not.

    I have seen problems like this on shared physical infrastructure systems where the activity on a system can interfere with each other.  Attention to this kind of thing, because if it is caused by another system then you will never find the cause of the problem inside the Oracle.  Examples include backups are made at a specific time, causing large amounts of sequential disk i/o and slows down access to the drive for everything else.  Such a scenario could cause some writing redo log time to increase significantly.  Or the backup could be another system completely who shares the same disks in the same drive bay or the SAN and Bay drives or SAN is inundated by applications e/s backup.  But as it's another system, that you will not see what is happening on your Oracle database system.

    Or a virtualized with environment sharing CPU and memory where another virtual machine running a CPU intensive job and steals the Oracle system CPU capacity.  I saw the same thing with memory so - Vmware has a strange way to virtualize memory, which means it can use all of the memory on the physical hardware and run out, and then he had to intervene to release somehow little memory.  What ends up slowing things down.

    It could be a network problem - is something that the network of the floods at 15:00?  Still, backups can be a common cause of this, during the transfer of data over the network to another system.  Is there a work extracted regularly data which runs at 15:00 for example extract given OLTP to feed into a data warehouse, which is copied on the network?

    It could be many different things, causing the slowdown.  I would definitely recommend watching any expected sessions know and see if this gets worse around 15:00, or if it remains the same, in which case the problem is elsewhere.  You must also eliminate everything else - the disks, network, etc.

    Good luck

  • R12.2 EBS in EXADATA

    Hi all

    Someone has known about EBS R12.2 in EXADATA?

    I understand exadata is just a RAC in SunOS?

    Is it possible to clone EBS in EXADATA to a server instance unique non-exadata?

    Thank you very much

    JC

    Yes. I've updated / installed 12.2.4/12.2.5 EBS on Exadata.

    You can clone of Exadata to Non-Exadata. You can use RMAN backups to clone as usual.

    However, if you use OHCC then you must decompress tables. You can do this using alter table... move; etc.

    Let me know if you need help more to that!
