many archivelogs, suggestion to reduce.

version 9208
I have a problem where a process creates too many files of newspapers to archive. When executed, it can create 1 + GB per minute and it is only a single process.

the apps team don't care about records to archives created by this process, so I did a tablespace with no logging specifically for her. Even the tablespace and table are no logging mode, it still creates a large number of archived files. The reason is is not a direct load of the data in the database, it is a process of type delete/insert/update to date.

In addition to adding more space to the directory archives and run archive more frequent use, or turn off the coast of archiving log (not an option at this point). Another way to reduce the documents created in the archive logs

So the process can produce 1 G again in 1 minute. So what! This should not make the process a problem. Get the proper disk, size your recovery adapted logs and make sure that the online redo logs as archived redo logs are spread over a number of adequately of the disk with the ability of e/s support to handle the load.

Direct path of loads can be not really an option. Unless you have the ability to re - run the DML in question, you can't afford to lose data.

Unless you can identify design flaws where it is unnecessary work such as changing data, reports about this, then make back the changes, or you can replace temporary tables for permanent work tables, you will have to bear the workload generated by the process.

    If you want to have 24 hours of archived recovery writes to the disk, you can ignore the backup in the same sequence over and over by configuring RMAN backup optimization. Then RMAN ignore archived redo logs that has already been backed up.

    Note configuration of backup optimization also ignores "identical data files" which has already been backed up as well. http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmconfb.htm#BRADV113

    Another way would be to edit your script a little

    run

    {

    backup ARCHIVELOG all not saved 1 time format ' / u01/arc_%d_%Y%M%D_%s_%p.arch' tag = "BKP_ARCHIVES";

    delete noprompt archivelog all completed before ' sysdate-1' saved 1 time to device type disk.»

  • Reduce the Rman backup time

    Dear expert;

    RMAN for level 0 backup takes about 05:26 hours, size of backup is now 312 GB I activated the block check the track and it reduces the time for the additional workforce 1 of 2 hours to nearly 3 minutes.

    database displays the largest storage space is "users".

    I want some useful suggestions to reduce his time or is it possible to break the level 0 backup. I can assign channels, but ultimately it will take time when you take 'users' tablepace backup
    For now, I take the backup on USB & his version is 2.0


    Concerning

    As you take backup on a USB there is not much that can be done to improve the speed. If you are worried about the backup to slow down... then you might think that taking the backup to local drive (which would be faster and more efficient) and then move the backups from disk on USB.
    This can be done in one script backup as part 2 operation.
    1) take backup on the disk.
    (2) copy the backup to USB key and delete the backups from disk.

    There are many additional features that you can add to improve it commentator.

    Hello:

    I recently bought a new hp laptop. I use it for entertainment. I had Windows 8.1 earlier when I bought. This 8.1 windows pc performance was not so satisfactory. So I downgraded to Windows 7.

It came with pre-installed Windows 8.1.  After a couple weeksI downgraded to windows 7. I bought windows 7 Ultimatex86 key of microsoft. Then I even went down to Widows xp I have...

    Now I will install my windows 7 Ultimate x 86 again. Give me a solution to fix the problem.

    Thank you.

    Hello

    I was provided with drivers to show you what is available for you and your laptop apart from Windows XP as Windows XP is no longer supported and drivers are not available. I have also provided drivers for Windows 7 on your laptop to HP 1000-1b10AU page because I wanted you to have access to updated drivers. Some of the available, he pilots have been updated between April and may.

    I suggested that you reinstall Windows 7 on the laptop. Here is a document called to perform a recovery of the system (Windows 7) HP for you and the options it suggests;

    "Your computer can have three types of available system recovery, or he might have only two. Use the type of recovery in order to solve your problem without making further changes as necessary.

    • System Recovery: This option reformats the system disk (usually C, reinstall the original operating system and reinstalls all the original hardware and software drivers.) \Recovery system does not affect the user created partitions. If there are two hard disks, System Recovery only changes the drive with the operating system.

    WARNING: If the size of the OS partition (usually C has been reduced below a minimum size requirement, other partitions created by the user will be removed and stored data will be deleted.)

    • Factory Reset: Reset deletes all partitions and reformat the entire hard drive, reinstall the original operating system reinstalls all the original hardware and software drivers. This option also recreates the necessary recovery partition (usually D and the UEFI system partition (usually E and reinstalls the software required.))

      The option of factory reset returns all software from the laptop to the condition as it was purchased in. All additions or changes user are deleted.

    • Minimizes Image Recovery: Available on many HP laptops, the reduced image recovery deletes all partitions, reformat the entire hard drive, reinstall the original operating system and hardware drivers and reinstall the HP essential (like HP Support Assistant HP Recovery Manager) software. Reduced Image recovery will not reinstall trial applications and games. »

    Please let me know which you choose to make, and how to charge Windows 7 goes for you.

  • Build exe error involvving internal.llb

    Hi all

    I have built many exe, but for some reason, this one is hard!  I get an error that says:

    Error 1003 has occurred at \\Rochester\mtp\Test Rigs\NC4\NC4 Air Cap\Code Development\Air CAP v2.0\exe\internal.llb\Air v2.1.vi Rig inspection Cap

    I spent reviewing the many forum posts that suggest that one of sub vi is not executable.  The main and all vi the subvi will be running in the labview environment.  I tried a forced compilation and even a massive compilation.  All to nothing does not.  This problem occurs on two different PC and build other similar thin vi, so I guess it isn't a problem with the manufacturer.

    I'm using LabVIEW 7.1, 8.0 Vision and IMAQ 3.5.1: see attached report for good measure.

    Can you help me?

    If you need to sub that VI let me know.

    Dan

    Hi Jordan,.

    I couldn't see anything wrong with the individual sub - vi and I tried your suggestions.  Turns out in the end a problem with the opening of the workbook with a password.  There is no security on the daughter to excel, but the vi has been programmed to use a.  If I removed the password of the vi it does not open so I added a password for the excel file and - hey presto! -everything works and relies on an exe file!

    I have not tried on the machine yet, but I am optimisic that it will work.

    I think it's for lack of microsofts!

    Thanks for your suggestions; you reduced to the excel link.

    See you soon,.

  • Background process untraceable on the event log service

    Hello

    I use a Windows 7 Enterprise system,

    ASUS X 99

    I7-5960 X

    GTX Titan

    This is a whole new system.

    Recently, the spinning wheel "working in the shadows" near the cursor doesn't disappear. I mean he will start a few seconds after the start and just stay there. It drove me crazy so I had to understand. I spent hours on the internet has tried many things. I have a little shrunken down, but still no solution. Here are some of the things I've done:

    (1) I went to Task Manager. I noticed that there is a constant use of the CPU by about 7% at all times. It is abnormal because idling all my other computers are still 0-1%. I went to the tab process to see what that was doing this. This is when things started to get interesting. There was no process using so much CPU. The system idle process will be 98-99%, but the CPU usage would be even at 7-8%.

    (2) I read on the internet a program called Explorer of progress, so I downloaded to see if it could track down. It's even more bizarre. The process exploring the use of the processor has 1-2%, as it should; While the Task Manager, it was still 7-8%!

    (3) many people suggested that this kind of thing can be linked to an infection by the virus. So I ran scans with Norton trial we had (also in safe mode), nothing. Then, I uninstalled, installed Malwarebytes, scanned and found nothing.

    (4) I checked the driver updates. I also completely uninstalled and reinstalled the graphics and USB drivers. No luck.

    (5) then, I did a clean boot (most of the services have been disabled) and voila! It was fine. So, he had to be linked to one of background services.

    (6) after a long trial and error, I reduced to a single service: Windows event log. The problem would not happen if I disabled this service of msconfig, then rebooted. However, I googled this service and it turns out that it's something quite essential for the operating system and I should not turn it off.

    So now, I hit a wall. I have absolutely no idea what to do (I'm considering an update of the BIOS but doubt strongly it would be useful). Before ask you, I don't know what preceded the problem. Many people use this computer and I don't know who started it. A clean installation of Windows is an option, but it would be a large number of deactivation/activation of the software is the last resort.

    I would appreciate help.

    Thank you.

  • RAW to Jpeg file size rule

    I wonder if there is a rule of thumb that can be used to predict the approximate size when exporting a raw file in Lr in a jpeg file.  For example, a raw average 25 MB file converting to about 5 MB jpeg with the export from Lr to 100 quality?  At about 3.5 MB with a quality of 80? …

    I know that can vary in size, but when I export a collection of raw files, and I put the maximum file size for a certain amount, Lr sometimes converts images because I limited the size too small.  I would like to be able to get a handle on some sort of relationship quality/file size before you begin the export process.

    I totally agree with Rob. JPEG file size limitation should not be used unless you absolutely care about the degradation of image quality. I can't imagine what application where it would be acceptable.

    Effectiveness of any given quality setting JPEG compression is generally of the order of 5:1. Using a means of file size limit will be saved images with detail to very high quality setting (i.e. 90-100) and images with the details is saved to many parameters of lower quality (0-50). It's the exact opposite of what you want to do!

    Unless you use a large file size limit size of exported JPEG images will probably visible JPEG artifacts. It's best to determine your threshold of acceptability for the JPEG artifacts (i.e. quality 50-70?) Use this quality setting for your exports without restriction of file size. The 'average file size' resulting will be less than with a larger file size limit.

    Tips to reduce further the size of the exported JPEG images files:

    (1) use conservative sharpening in the modules to develop and export (i.e. not too narrow)

    (2) use the color and Luminance Noise Reduction sufficient settings to reduce visible noise in the image.

    (3) make sure that 'remove the Chromatic Aberration "is checked in the color of the lenses Corrections Panel."

    Following the above suggestions can reduce the size of the JPEG file exported by 50% or more, especially for raw ISO images files high.

  • upgrade to 11g of 10.2.0.4 in SUSE 10.

    Hi gurus,

    We have upgraded database 11g on our EBS 11i environment, the database size is about 1.3 TB, I already test upgrade, this was no positive results expected this as a customer on downtime, I followed the manual upgrade since I am quite familiar with this I have your comments and suggestions to reduce the downtime upgrade...

    upgrade to 11g of 10.2.0.4 in SUSE 10.

    Hello

    Is that your database is RAC or NON-RAC.
    If you go to the Group of patches upgrade, then you can go for patch update of roll .

    as you know, you can't always escape the downtime. ;-)

    I already test upgrade, that it was not positive results is expected this as a customer on downtime, I followed the manual upgrade because I'm quite familiar with that

    Oracle always throws DBUA with many features, why you won't find DBUA?

    You should test the TEST using DBUA environment ;-)

    If for example to 1.3 TB you consistent backup, you still have the downtime. then it is useless to think on the duration of the UPGRADE .

    but you can do proactively as... to install 11g ORACLE_HOME before downtime. & so on.

  • Cannot mount Freecom NAS

    I searched on the web and this forum several times for a suggestion of what has happened to my NAS access, but never found a solution despite trying many things suggested.

    I have a (Freecom) external HARD drive sitting on my home network with its own fixed IP address. On this disc, I have a number of actions implemented. One was created specially for me store related things Mac when I got my Powerbook in 2006. I used to have no problem to access this share of OS X Leopard (I know, it was a long time ago). Nothing has changed on the disk, but I can access it from my new Mac (Macbook Pro, El Capitan)? N °

    If I browse the network, I see the player, if I click on the drive that I see the actions, then when I try and open sharing, sometimes I'm invited connection credentials, sometimes I'm not, but the result is always the same: there was a problem connecting to the server "Freecom" check the server name or IP address, and then try again. If you continue to have problems, contact your system administrator.

    Maybe I shouldn't give myself credit for being the administrator of the system, but it is the situation that I am, so where do I turn?

    I can access the web player access page and create new actions, but it is not always accessible. There permissions configurable through the interface, in the past, I always guest access. It is extremely frustrating that I wish that someone could point to a possible origin.

    I dove into the world of terminal and created a nsmb.conf file in an effort to solve the problem, but I can't control here and can only work parrot fashion, not really understanding what I'm doing.

    If anyone can offer advice, I would be very grateful.

  • Will not activate my iPhone iMessage/FaceTime

    I have an iPhone 6 s (T-Mobile carrier) and recently updated to iOS 9.3.4.

    Last night my iMessage ceased to deliver my messages in two group discussions and would only send messages through text messages that received no my friends. A friend uses his email on his iPod for cat. I couldn't send anyone or a group of messages to anyone in these group discussions, but I could always send messages to other people. My FaceTime work again very well. So this afternoon I was looking for solutions to this problem. Many people suggested closing iMessage and FT, then by restarting my phone, I did. But when I turned my phone on iMessage and FT wouldn't activate. Since then the iMessages and FT have tried to activate, but kept a failure, errors, or servers have failed. I can't send messages or FaceTime anyone.

    I tried:

    The network reset

    Change the Date and time on Auto

    Ignition and extinction of iMessage/FT

    I also try to discuss with the Apple Support, but it takes awhile.
