optimize the size of the temp and redo files

Hi gurus,

y at - he of the formulas for finding the optimal size of temporary storage and redo logs groups.

If redo log groups are often fill what steps to do.

I know the formula for the optimal size of undo tablespace: rate of transactions * the undo tablespace retention policy * block size

Please let me know the solution of problems.

Thank you!

In general, I try to shoot for redo log files exchange once every 20 minutes. However, in many systems, there can be a wide range of time swap, depending on the workload.

In regards to the temp, it's pretty easy. Define up to about 32 MB w/autoextend on and let it grow to be larger because it must be. Once that happens, it will be virtually stable at this size - until something new comes along and he needs to grow even more.

    Last year, I bought my laptop and I tried to create a second user account but I placed it somehow this account as the Admin user. I don't remember the password and my file vault is of course.

    What password? You can change a password for the account, but if you do not know the FileVault password, you are in a bind. You need to call Apple directly if you their sent an emergency password when configuring the FV.

    For a user account:

    You forgot your password

    IM able to search the F drive and the list of all the .bat files using a generic parameter, but ideally id like to search for .bat and .cmd files, but whenever I have it try does not work. Any ideas?

    I tried the following:

    dir c:\>desktop\file.txt/OD
    dir d:\>>desktop\file.txt
    dir f:\jobs\*.bat,*.cmd>>desktop\file.txt/OD

    Any help is appreciated, the reason for which I need to check all the .bat and .cmd files is to ensure that the scripts on a cluster are all data, so need them all listed in a doc if possible

  • the .c and .h files still open in CVI 9.0 even with CVI 2009 is installed

    I had this problem for a while but have managed to live with her. Since I installed LabWindows/CVI 2009 my .c and .h files still open in LabWindows/CVI 9.0. all .cws, .fp, .uir and .prj files will open in 2009. I tried the files in "file types" remapping and even fiddled with the registry to try to get the .c and .h files to open with the correct version of the CVI. This has been without success.

    Any help would be appreciated.

    Thank you!

    I found myself fixing entering into the registry and change the path to cvi.exe. He was always set the path to the executable file for CVI 9.0. That's what the types of files for .c and .h files were SEO even if I selected the executable file in 2009 of the CVI.

    It seems that the path was never changed when I installed CVI 2009.

  • What is the Temp etilqs xKTXRBvWnu6 file?

    Everytime I open my browser Firefox Win Patrol reports a hidden file. I use XP Pro with SP2, and they are always under C:\Documents and owner Settings\Temp. These files always have etilqs as a prefix with the last group of numbers and letters of Exchange to the next time I open Firefox. It's more embarrassing, it's more boring near harassment, having to respond to the report of WinPatrol. There is no way to ignore it in Win Patrol settings so I have to uninstall Win Patrol or Firefox. Do you know what are these hidden temporary files and how can I stop being a constant nuisance whenever I try to use Firefox? Thanks for any help you can give me.

    WinPatrol is tenacious tell you these because that you have enabled the cookies of the monitor, which is not recommended.

    For instance, you may see many files that start as etilqs_ followed by random names. These are database files used by the public domain database called SQLite. Both Chrome and FireFox use SQLite to store data including cookies.  Another common hidden legitimate file will start with api-ms-win- or ext-ms-win.

  • evolution of the coast on the .avi and .wmv files

    Have windows vista 64 bits, windows media player 11.  Have the movies, photos and music on my computer.  Have a PS3 in the living room that I use to watch movies, look at pictures and listen to music.  Everything works fine as long as the media is in the correct format.  My son has a PSP using remote play to sign in on the PS3 and it can watch movies, etc. on his PSP.

    Problem:  Can not figure out how to limit some of the media to keep my son 8 years of viewing/listening to him.  Parental controls on the PSP, etc don't allow you to restrict the DVD and Blu - Ray content.  In WMP, I noticed that you can limit the content that is visible to other network devices to "unrated", which could solve the problem if I could change the rating.  All video files just to say "unrated" and it doesn't seem to be a way to change this.

    Question:  How can I limit some media files so that my son can not simply watch r rated movies etc. in addition to remove them all together?

    Hello rmasroor,

    Thanks for your reply and your interest.

    I'm fine and hope you are too. Problem no longer exists. Sorry that I didn't write to the topic, but now is fixed. The problem is that I probably forgot my password private, so I asked RIM to send me other keys. Now, I've been more careful with the procedure, and all were very good.

    Please update this topic as fixed or solved.

    Sincerely,

  • How to back up and restore the system and program files to install new OS

    Hey all,.

    I recently bought a new Toshiba 1 TB HARD drive. My old WD 1 TB HARD drive was giving me the end. occasionally, I get the BSOD. In addition, on occasion, when I restart the computer it automatically runs chkdsk program and reported several bad clusters. However the chkdsk program never seems to report the bad clusters, so periodically, when I restart, it runs and bring back them again.

    I would like to the image or to back up all the files on my HARD drive problem, then do a fresh install of Win 7 Ultimate 64 bit (my current operating system) to the new HARD disk, and then restore the clone or image system and program files on the new HARD drive. I don't want to go through the process of reinstall all again, when everything seems to work very well. Given that the image of Win 7 program makes and accurate picture of the HARD drive, then use this program would cause the new installation of Win 7 Ultimate 64 bit to be replaced by the restoration of the image. Therefore, if there should be corrupted data under a bad cluster of old HARD drive, that data would not be transferred and my existing problem would be transferred to the new HARD drive.

    On the other hand, if I do a clone of disc, I'm not sure that existing programs would continue to operate on the new HARD drive and would require a new install of each program based on the new installation of the operating system Win 7! I would have then lost my time to make a transfer of program/data files to my newly formatted and freshly installed OS.

    Anyone know of any program (Acronis True Image, Paragon, Norton Ghost, Macrium Reflect, etc) that will allow you to image or clone the program and data (including the operational needs of the files such as: Win32 system files, files of activation, etc.) so that they will work properly on the new installation of the operating system?

    Any help would be greatly appreciated. Have a great day.

  • Optimize the download of static files in APEX developemnt

    Heyo!

    I use apex 4.2.6.

    Scenario:

    I use the js or css custom referenced in my application file. Whenever I need to change something that I have to open my file in my editor (ST3), edit it, save it, remove the old static file in the apex, download the new and then check the results.

    It is extremely tedious. Is there an easier way? Something like from the file system? Just while I am in the process of development.

    Yes. It contains the files of images/js/css for the constructor of the APEX. But you can create a new folder at the location of the East and store your images/js/css application files and send them using the #IMAGE_PREFIX #yourfolder/yourfile.js, instead of upload to SEO and the shared components using #APP_IMAGES # #WORKSPACE_IMAGES or #.
