Overhead of the audit

We use audit_trail = DB, ELONGATED or are currently audit connections only (successful and unsuccessful). Is there a a way to evaluate the overhead generated by doing this (compared to the default audit_trail = NONE)?

Our databases are 10.2.0.5 and 11.2.0.3.

Thank you
Mike

See below the link that I liked a lot for performance issues related to auditing settings.
Its give you the table n the end that tells you the air performance for a different setting of the audit.

http://www.Oracle.com/technetwork/database/Audit-Vault/learnmore/TWP-security-auditperformance-166655.PDF

Looking at it you will notice you 14,09 flow additional time and 15.79% of additional CPU use with DB, EXTENDED setting

I hope this will help

  • Failure of the audit on the iPhone, but works in iTunes

    Hello

    I had a strange problem:

    I can log on successfully to my desktop (Windows) by using my AppleID, can see my account balance and buy free apps.

    But I use the same AppleID on my iPhone 6Plus, it always shows: "failure of the audit, your Apple ID or password is incorrect."

    can anyone help?

    Thank you very much.

    Hi all

    After 2 hours of research and new attempts, I finally solved this problem.

    1. just to keep a new attempt on the iPhone, until the account is locked.

    (Note, only the account on the iPhone is locked, can I still use iTunes Windows and web to connect on the same Apple ID]

    2. then follow the instructions on the screen to unlock the account.

    (you will be asked 2 secret questions when the account is set up a few years ago)...

    Once the reset is OK, the same account is included to connect the iPhone and buy apps.  (Yes..!)

    Hope this will be useful.

  • SQL Server 2008R2 Server Audit - HostName Will be included in the audit information?

    I'm testing audit Server, and it really works so well. Many articles and examples are available and it is very simple. The output shows all the necessary information as well, what was the change, that did it, BUT not change where. (Workstation or even IP address?)

    We have an application that runs under an application service account that makes changes to the database. The application can be run from different hosts and would be really nice if the audit can display this information as well.
    Am I missing just this information? or is it just an audit framework, I need to turn on as well to include this information?
    If it is not included in all information, is there any plan of it in the future, including updates?

    Thank you very much!

  • Overhead of the graphic use of Wfm as a Subvi output terminal?

    -My basic question:
    If the front is closed, is there a difference between a graph of Wfm and Wfm indicator as output terminal?

    -The question in context:
    I have a no reentrante Subvi, which will take place in my program and an output waveform.  Sometimes, I want to open the front of the Subvi and adjust its internal settings displaying its output on a graph of Wfm.

    The minimum solution would appear to make the graph of Wfm of the Subvi double panel as the output terminal, as opposed to the output through an indicator of Wfm.  But who would increase the resources used during normal operation of the Subvi?

    Thanks in advance and have a nice day.

    -Brad

    There should be no overhead. The chart would update only if the front is open. Most of the time, there are not yet signs before the subVIs in memory.

  • Backup process takes about 17 hours, which includes the audit of 18 GB of data

    I backed up my system Windows XP Home edition on an external hard drive with the NTBackup utility system.  This process takes about 17 hours, which includes the audit of 18 GB of data.  Is there a problem with backup on my system causing this slow time of execution?

    Now, I created a disk image of my system using the NTBackup utility of the system from the installation disc, and also, it takes about 17 hours.  There may be some kind of hardware problem.

    My computer has installed in USB1 and translates into a slow backup.

    NTBackup is one of the worst possible for the backup options (as you can see from your experience). I can recommend a far superior alternative. But first, you must let us know what your goal is:

    1. regularly back up data ONLY (for example Word documents, photos, mp3s, etc.)?
    or
    2. make incremental copies perfect bootable on your system, including all service packs, updates, installed programs, etc. (and possibly your data as well)?

  • Limit regarding the Audit trail cleaning

    Hello

    I have a RDBMS Oracle 11g, which makes use of the Standard Audit trail.

    I like to keep the audit for 3 months from the date, cleanup runs, which means that have the Audit trail for 3 months, back from the date I'm looking at.

    But I read that there is a limit of 999 hours to set "cleaning interval."

    For copyrighted I ise a regular as program:

    BEGIN

    DBMS_AUDIT_MGMT. () SET_AUDIT_TRAIL_PROPERTY

    AUDIT_TRAIL_TYPE = > DBMS_AUDIT_MGMT. AUDIT_TRAIL_AUD_STD,

    AUDIT_TRAIL_PROPERTY = > DBMS_AUDIT_MGMT. CLEAN_UP_INTERVAL,

    AUDIT_TRAIL_PROPERTY_VALUE = > 999);

    END;

    /


    Can anyone confirm if this is correct or not?

    If so, this also applies to Oracle RDBMS 12 c.

    Thank you in advance.

    Kind regards

    Laury, the cleanup interval is how much work to purge works, not how long the data are kept.  So the limit of 999 hours isn't a consideration for your target.  I suggest that you run the purge not less than every day.

  • Is it possible batch redact handwritten numbers as the Bank, the audit of the accounts?

    Hello

    Is it possible batch redact handwritten numbers as the Bank, the audit of the accounts?

    We have loan documents and a single page is filled by the customer for the ACH.

    They provide their info from debit card or cheque for payment account.

    These are written by hand, and so far I can't have Adobe to recognize numbers, even though they are in the standard format.

    If this is not possible, batch Adobe may delete the page in question as a lot?

    Thank you very much, Paul

    -If the texts always appear in the same physical location on the page, then you can use a script to redact this area, Yes.

    -Otherwise, you can easily delete the entire page.
