default 10g Auto Gather Stats Job running NECESSARY or NOT?

Hello
our database is 10 gr 2
Operating system is windows


in my 10g database, I already have a regular job of running statistics which collects level schema statistics. There is only 1 schema of the application.


Is it necessary to permanently keep the Oracle default 10g Auto collect Stats Job?


If two jobs are running (default 10 g auto gather stats job running in the window management 22:00 to 06:00) and our stats of manual diagram gathering job (market every day at 7 to 11) then that statistical jobs would be examined by CBO. ?

should I deactivate default job statistics?

Thank you...

Probably the Oracle supplied job is "smarter" that no matter what mechanism you provided.
I will disable your own job.
The Oracle supplied job only collects outdated statistics, outside office hours.
Your business brings together (all? / stale?) statistics during office hours. Your job may fail due to the ora-0054.
Collection of statistics of segment during office hours is not desirable. Collection of statistics of system during office hours may be desirable.

    Hello

    You may need to restart the database (or instance) which the job runs. Restart the Oracle Job Scheduler Windows service can also work.

    Once you have done this, see this post to rewrite your job (stdout/stderr redirection) and pass arguments as separate argument values.

    Guide to the external work on with dbms_scheduler 10g for example scripts, batch files

    Hope this helps,

  • Default value of the string at run time control

    Hello world

    When I'm editing mode, I can click with the right button on a control of the chain and go under "Information Operations" and select "Make default value"... I need to do in run mode, but I can't find a property that gets the job done.

    Any suggestions?

    Thank you

    Hi love,

    My advice is to init the checkpoints of your application with the ini files. Do you have an API for the name VI configuration file. That way, you can change the default between every time the application runs.

    Explain here.

    How can I do? Even if DBA_SCHEDULER_JOBS. ENABLED column is TRUE. The work does not in fact.

    You need to investigate the failures of the tasks using DBA_SCHEDULER_JOB_LOG:

    select log_date, status, additional_info from dba_scheduler_job_log where job_name='GATHER_STATS_JOB';
    

    You should always find information in the dictionary for the jobs to DBMS_SCHEDULER (unlike DBMS_JOB which records employment errors in the log of the instance alerts).

  • Reset the default printer after each print job.

    I wish that my printer to reassign the default printer after each print job.  I have a Hp LaserJet 1020 on my desk as my default.  Sometimes however, I print on our printer color etc.  Then when I go to print again immediately after the color printing - it is (and not my default).  I looked in the printer properties, devices, etc. - but do not see where I could update this?  Can you let me know.  Thank you.

    You don't say how you make that decision to change printers. I have two printers, all-in-one (default) HP4135 and HP6122 duplexer.

    Example: Leave in MS Office Word 2007 default print would always be. But I can choose a printer to use. With this selection, as long as I stay within this project, the HP6122 could be used. It would default to the HP4135 if I closed the project.

    If you go: start, Control Panel, printers, you will see all printers. The default value has a green check mark. Right-click on the printer icon and a menu descends with an extra function "Set as default printer".

  • Firefox says it is already running, but is not!

    Error message states: "firefox is already running but is not responding. to open a new window, you must first close the existing firefox process, or restart your system. ;

    I rebooted and no effect.

  • Firefox is already running but is not responding. The old process of Firefox must be closed to open a new window.

    When I try to open Firefox, I get this message:
    "Firefox is already running but is not responding. The old process of Firefox must be closed to open a new window. »
    I then clicked close firefox, but the problem was solved not so I uninstalled and reinstalled firefox, but it's the same thing.
    At this point, I went to support Mozilla and tried the steps described in the article, "Firefox is already running but is not responsible for - How to fix error message", but the firefox.exe process was not in the processes tab in windows Task Manager. While he was in the Details tab, when I tried to put an end to the process, I received this message:

    "The operation could not be completed. Access is denied. "

    What can I do to fix this?

    Thank you.

    Usually when you stop and restart Windows, Firefox is not running and can be started normally.

    Firefox is set to start automatically with Windows? Microsoft has a utility to investigate what is set to happen at startup: https://technet.microsoft.com/en-us/sysinternals/bb963902.aspx

    It is possible that something is triggering a process in your default browser and it is the hanging of Firefox. You can try to change your default browser to IE (IE can offer to do when you start) before the shutdown and restart Windows to see if it makes a difference.

    You are able to start Firefox in Safe Mode or start the Profile Manager?

    (1) safe Mode

    It is a standard diagnostic tool to disable some advanced features of Firefox and extensions. More info: questions to troubleshoot Firefox in Safe Mode.

    You can start Firefox in Safe Mode by holding down the SHIFT key when you start Firefox. (If you get directly in a new window, you must exit all Firefox Windows first).

    A small dialog box should appear. Click on 'Start mode safe' (not reset).

    It will start?

    (2) the Profile Manager

    This assumes that firefox.exe is not running.

    Start in Manager profiles using Start > Search box (or run):

    firefox.exe -P
    

    When you get the Profile Manager window, do not delete anything!

    No matter what time you want to switch profiles, you exit Firefox and return to this dialog box.

    If you select your default profile and click Start, Firefox start?

  • Firefox is already running but is not responding? Simple answers don't seem to work

    I started Firefox earlier today and received a message about a problem with Firefox and he had to be reset. Because the other option seemed worse than the reset, and Firefox Reseting seemed relatively painless, I clicked OK. A short message popped up on the registration of passwords, bookmarks, etc. with success. Then a small window pops up, saying it was cleaning of Firefox. While the process seemed to freeze. I liquidated it, killed at any process of firefox running and attempted to restart Firefox, when I received the message "Firefox is already running, but does not." There is a folder on my desktop labeled 'old Firefox data' which I assume is from Firefox reset (it is also now a copy of the profile on my desk, just in case).

    https://support.Mozilla.org/en-us/KB/Firefox-already-running-not-responding

    I found this and tried to work through it, but it doesn't seem to help.

    (1) Ther' are no Firefox.exe in my task manager, nor is there a process plugin-container.

    (2) I deleted the file "parent.lock" in both the profile (which is just a bunch of jumbled letters and numbers with 'default' in it) and the record of the old Firefox. However, these files were just "parent.lock" not "parent.lock.parentlock".

    (3) did not change the name on it, so unless the reset did before she locked herself, I don't know what to change it to.

    (4) it is not a file share, so...

    (5) this could be a possibility. The folder of Firefox that my profile is 'Read only' is, but I can't not to change cela. Everytime I go in, turn off the 'Read only' option and tell him to propagate the change through subfolders, it seems to work, but when I check the properties 10 seconds later, 'Read Only' is checked again.

    Sounds that the profiles.ini was corrupted when you remove the old default profile and adding the new profile.

    You can have security software that preventing to change the Firefox file.

    You use the Profile Manager to restore an existing profile or create a new profile.

    A "Reset" creates a new default profile with a timestamp attached and is trying to import some settings of the old profile, leaving the old profile intact, including the (invalid) cache folder (topic: cache) can take up to 1 GB.

    Versions of Firefox 15 + will move the old profile folder "old Firefox Data-#" folder on the desktop that gets a figure if you use reset several times, so you can no longer use the Profile Manager to return to the old profile.
