Is CTSS will take care of Day light Saving changes

Hello,
In our enviornemt we used CTSS(cluster time synchronization service) in 2 node RAC,NTP services is stopped on Linux nodes.
DST will going to happens on 27-Mar-2015, so is CTSS will take care of DST changes automatically,if not what needs do to care of it.
Thanks in Advance.

Far as I know the awnser is NO.
The role of CTSS is keep same date/time in all nodes no matter if date/time is right or wrong, (it not fix date or set DST or something else), during clusterware startup if all nodes has same date/time CTSS choose randomly a node as master and keep other nodes updated using master node as reference. So, if the date/time of master node is wrong all nodes will get a wrong time.
Is highly recommend to use NTP Service instead use of CTSS. When using NTP the CTSS run in observer mode.
Change Date/time or set DST is role of OS (Linux), not Oracle Clusterware. You must check on OS how it was configured.

  • Day Light Saving Changes for Europe

    Hi,
      We are using SQL Azure databases in North Europe location. 
    When trying to use GETDATE() function, it is not considering the day light saving changes and brings back the time less by an hour.
    Is that something that we need to or can do on the server or database
    Having issues in saved records even for auditing purposes.
    Any help will be highly appreciated
    Many thanks

    When trying to use GETDATE() function, it is not considering the day light saving changes
    Hello Deepu,
    All SQL Azure server in all Azure locations (America, Europe, Asia, etc) returns for GETDATE always the same value: The current UTC date time. No time zone offset, no daylight saving, always UTC only. You can simply check it with this query:
    select GETDATE(), GETUTCDATE()

  • Day light saving changes in UCCX scripting.

    Hi, We are using UCCX version 8.X  and we have script like press 1 to go shangai tem, press 2 to go to US team like that.
    In the time of day light saving we are doing manual changes in time of day settings manually when ever the location day light savings changes.
    so is there a way to the script refer the local time zone according to the region day light savings.
    or the reqired OS patched time zone patches will solve the problem please suggests.
    Thank you.
    Baskaran.

    Hi,
    UCCX uses its own time in the server to lookup the time. you need to configure the proper timezone for your UCCX. if shangai and US change start using daylight saving at the same date, you don't need to change your script. if not, unfortunately you need to change the time in the script itself.

  • How to disable Day Light Saving Change with GMT-5 TimeZone ?

    Hi,
    I want to use a Calendar object for date manipulation, but I want
    to disabled DST, because it adds and removes 1 hour depending
    on the calculation.
    I took a look at severals books but without success. I found a solution at
    http://mindprod.com/jgloss/gotchas.html#DATE , but it uses UTC TimeZone
    which is innapropriate in my case. I must use date with the GMT-5 TimeZone
    I want to know if there's a way to disable DST for the GMT-5 TimeZone ?
    Thanks in advance ?

    I want to know if there's a way to disable DST for the GMT-5 TimeZone ?Yes, but have you tried
      TimeZone.getTimeZone("GMT-5")? In theory, that should give you a DST-invariant time zone 5 hours behind GMT.
    When I just tried at (at 10:45AM PDT here), I got a time of 12:45 with this timezone (by using a SimpleDateFormat with this timezone to format a new Date()), which shows that it is ignoring DST.

  • Does anyone know if loading the new OS will take care of a malware problem?

    Does anyone know if loading the new OS will take care of a malware problem with Safari?

    You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
    Back up all data before making any changes.
    One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
    If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
    Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
    Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
    In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere  should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
    Still in System Preferences, open the App Store or Software Update pane and check the box marked
              Install system data files and security updates (OS X 10.10 or later)
    or
              Download updates automatically (OS X 10.9 or earlier)
    if it's not already checked.

  • HT3231 I am migrating about 450GB from my MacBook White to my MacBook Pro, wirelessly and it will take over three days, having spent 18 hours on the first 15%. Is it possible to interrupt this migation without damaging either source or target?

    I am migrating about 450GB from my MacBook White to my MacBook Pro, wirelessly and it will take over three days, having spent 18 hours on the first 15%. Is it possible to interrupt this migation without damaging either source or target?
    On reflection I should have used a wired connection or migrated at a later time but is it possible to interrupt the process now and rerun with a wired solution without damaging either laptop?

    I have two iTunes libraries - about 172GB that I keep on my MacBook Pro and 500GB+ that I keep on an external drive. If you wanted to do something similar - keeping that precious internal space to a minimum - you can just create two libraries and hold down the option key when opening iTunes: this allows you to select which library you want to open.
    Just a thought...

  • EDM price profile upload process and Day light saving issue

    we have a requirement to upload EDM price profile (with 60 min interval).  Which are the function module or BAPI's are there to upload the price profile in EDM. Also which table holds this dat. I guess it is EPROFVAL60 and can be seen using transaction EEDM01.
    Also, there is a scenario of DST (day light saving- US client) mean sometime there will be 23hrs value or sometime 25 value. How to handle this. I guess all this price value store in table EPROFVAL60 (hourly value) but the structure of this table can take 24 hrs value. Any suggestion on this.

    In the profile header there is the field u201CTime Zoneu201D. There the specification of
    Time Zone for EDM Objects is possible, e. g. where an installation is billed or profile data is displayed.
    The configuration in IMG u2013 customizing leads to the transaction STZAC and STZBC.
    This updates the tables: TTZD - Summer time rules or TTZDV - Summer time rules (variable dates)
    Please watch the OSS notes frequently, since there are some updates lately.
    Kind regards, Tom

    Hi,
    In our application log gets printed with the system's timestamp value.If for Summer time or Day Light saving purpose if the timing gets changed, will it affect in any way, the way the log content with timestamp is written to the logs? Please suggest how to handle the day light saving scenario in java ?
    Regards,
    Asha

    No, unless you're running your software in Australia or USA or (bunch of other countries whose DST rules have changed or will change soon), which covers a very large user base :-).
    In which case you should be running the latest update of your version (in your case, 1.4.2_11, I think, but check to be sure).
    TimeZone rules keep changing in various countries as legislative bodies love to tinker with that sort of stuff, so you should always keep to the latest update for whatever version you choose to run on.

  • Day light saving effect on standby databases

    Regards,
    Prasad.Nothing to do with time in terms of Standby databases.
    Its applicable only in RAC environment, where you should have same time acceptable < 30 seconds around.
    One of my earlier post, i given example, pasting again
    Lets example:-
    Primary database is in Far North - Canada
    Standby Database is in Bangalore - India
    So here time zones are completely different, at least 12 hours difference. So there is no need to be same time in DR environment.
