Changing system date

Hi,
I have a 11.2 database + oracle EBS on a linux machine with a wrong date time. What will happen to database and ebs if I change the time an hour back from actual?

  • Changing system date in Paravirtualized  Oracle VM

    Hi ,
    I need 3 guest on 1 oracle VM server. Each of them has own different system date. For example while first one is working on 2041 , second one works on 2001 and last one works on 2014.
    I have set "xen.independent_wallclock = 1" in "/etc/sysctl.cfg" in each Guest and I am able to change system date as independently from host system. Until here , everything is ok.
    But when I restart the Guest system , the system date is resetting to host system's system date .
    Please could you give your ideas how to solve this problem .
    Rgds.

    Hi, for paravirtualized guests do like this:
    As user root
    vi /etc/sysctl.confsearch "independent_wallclock" and set it "=0" (NOT "=1")
    Save and exit
    Set the correct Time Zone creating an appropriate symbolic link, for example:
    ln -sf ../usr/share/zoneinfo/Europe/Rome /etc/localtimeThen:
    vi /etc/sysconfig/clockSet it as you like, but following this schema:
    ZONE="Europe/Rome"
    UTC=false
    ARC=false("ZONE" refers to the Time Zone, "UTC=false" indicates that LOCAL TIME will be used)
    Finally, deactivate the ntpd service on your VM guest, as with the above settings system time will be bound to the Hardware Clock on Dom0, therefore we don't need ntpd:
    chkconfig --del ntpd
    service ntpd stopTry a reboot and check all is ok.
    All this, I repeat, is true for Paravirtualized guests only. Fully Virtualized guests do need ntpd service for system tyme sync.

  • Change system date??

    Hi,
    I just wonder if we can refresh the B1 after we change the system date in the OS without restarting the B1 application itself.. because restarting the B1 take quite a time for my laptop...
    Actually there was once i tried to lock screen the application, when i logged in back, the date was refreshed, but i can't do that anymore and i don't know why that day i could.
    Thanks,
    Martin

    Martin,
    The SAP client at the time of login takes the system date and I don't think there is any way to refresh without loging out and loging back in

  • Can we change system date from sql prompt

    hi everyone
    can someone tell if we can change the system date from the sql
    prompt??
    Tariq.

    I don't think that the date/time last modified is accessible.  You could use the SummaryInfo of the report to maintain this information yourself.  This is part of the RAS SDK.  There is a comments section available that you could use for this.

    8. restart DomN as root
    *[root@bcvlnx12 ~]# shutdown -r -t 0 now*
    Broadcast message from root (pts/1) (Sun Jul  7 00:05:20 2030):
    The system is going down for reboot NOW!
    9. login again as root after restart

  • Consequences of changing system date

    for some reason i need to change the system date on production server (sms server with a database)
    only the year should decrease by two (minus 2 years)
    before changing the date i want to get some advice from the community
    what problems could happen after that, what steps should i follow before doing that, etc
    the things that i've already taken care of are CRON and AT jobs
    i think there could be problems with file access/modification dates and anything that relies on them
    can it be solved by just updating access/modification dates of all files accordingly?
    please give advice
    thanks in advance

    i'd wonder what happens if your server sends 2 year old SMS to the SMSC and receives SMS dating 2 years in the future :>
    consider buying a new license
    that kind of problems wont happen since new outgoing messages are selected using different/additional criteria
    moreover it's not only about this particular case
    it's a real problem, i would be interested to get some (new) advices even i decide to buy new license

  • System data change....

    Hi all,
    when I log in my XI server says "License expiration data:01-11-2008(in 9 days)
    I know that I have to change the system date, but I need to know procedure
    to be followed before changing system date.
    Pl. help me out.
    Regards,
    Pankaj.

    Hello Pankaj,
    This means that you need to apply for license and not change system date.Please apply for license.
    Of course changing system date will make this problem not re occur but then such system will not be supported by SAP.

  • Not able to change the data of test data containers in production system

    Dear All,
    We have created eCATT scripts in Development SolMan System and moved the transports to Production SolMan System.  Customer wants to change the data at Test data containers and run the scripts in production system but we are not able to edit the data. 
    May be the reason is SCC4 transaction code has set the below option.
    Changes and transports for client-specific Objects
    u2022 No changes allowed
    Customer doesnu2019t want to change the above option and wanted to change the test data containers to give different datau2019s and run the eCATT scripts.
    Could you please let me know the solution for this?
    Your help is really appreciated.
    Thanks,
    Mahendra

    eCatt has the feature where you don't need to transport the scripts or test configuration to our target system. We can keep all our scripts and test data in Solman and run this script any other system in your landscape using the System data container and target system.
    Maintain the production as one of the target system in System container in Solman and point that system while running the script. Change the test data in Solman to run this script.
    Let me know if you need more information
    thanks

    Thanks
    Paresh

    Hi Paresh,
    You can proceed with deleting your SAP system from SMSY (along with connected technical content such as AS Java definition) and the run the LANDSCAPE FETCH through transaction SMSY_SETUP to have the correct definition of your SAP system in SMSY.
    Following this, you could use the addon Landscape Verification (a new thing I learnt today!!!)  to check the correctness of transaction SMSY. The following link details the Landscape verification 1.0 for SolMan:

  • My laptop died last night and the date and time was set for 1/1/2000. I went to change the date and time and cannot. For some reason when i pull up system preferences it will not load date and time but will load other stuff. Please help.

    Last night my laptop died and the time and date was reset. I cannot acess date and time preferences to change it and my laptop is acting really weird. My CD drive is broken so there are no options to put in a cd. Please someone help i need my laptop for school and cannot afford another.

    Many system actions will misbehave, given an inaccurate date. Resetting the NVRAM and / or SMC will not fix it, and if the system has a preposterous date you may not be able to open System Preferences to correct it. This dilemma may or may not be addressed in a future OS X update.
    If you cannot open System Preferences you can reset your system date and time using Terminal.
    Please read everything that follows before proceeding. Write them down if necessary because the effects of setting a preposterous system date are unpredictable.
    Quit System Preferences, force quit if necessary: OS X: How to quit an unresponsive application using Force Quit
    Open Terminal - it is in your Utilities folder and looks like this
    You can find Terminal by using the Finder's Go menu and choosing Utilities, then double-click the Terminal icon.
    At the prompt, you will be typing a command resembling the following:
    sudo date mmddhhnnyyyy
    ... but you must substitute the actual date and time in the command that corresponds to the date format used for your location. In other words if your custom is to use a date like 8 February 2014 then reverse the mm and dd values.
    Substitute numerals in the above command according to the following:
    mm = month
    dd = date
    hh = hour (24 hour format)
    nn = minutes past the hour
    yyyy = year
    Each of those values must be two digits except for the year which can be two or four digits. As an example if the current date and time is February 8, 2014 at 9 PM your command will be the following:
    sudo date 020821002014
    or
    sudo date 0208210014
    Either one will work. If you enter nonsensical values the system will attempt to parse the entry correctly.
    To recover from your inability to use System Preferences to set the date and time, the value entered does not have to be precise, it just has to be approximate.
    Enter that command using the actual time and date for your location and in the appropriate format, then press the Return key. Terminal will ask for your Admin Password - the same one you use when you log in to your Mac. Type it and then press the Return key. What you type will not appear, not even with •••• characters.
    To determine if your change was effective just type the date command and press the Return key. Terminal will reply with the date and time. If it appears correct and in the correct format, you should be able to open System Preferences > Date & Time once again. Selecting the "Set time and date automatically" and choosing an appropriate time server will adjust your Mac's system clock to the precise time.

  • Change master data of business consolidation directly in the quality system

    Dear All,
    I need to change master data of business consolidation directly in the quality system.
    Anyone an idea?
    Kind regards,
    Marilia

    Welcome to SDN.
    There are SAP Notes 933024, 804057 and 592239 that provide a means of opening UCWB only for master data objects.
    Another possible work around is to make the updates in BW and use the synchronization programs UGMDSYNC and UGMDSY20. However for FS Items and Cons Groups all of the master data elements such as breakdown category and period of first consolidation are not available for entry in BW so for these characteristics the maintenance must still be completed in UCWB.
