How to configure time zone information in the failover database

Hello:

I'm confused on what to do with a failover system time zone information. Here's the situation:

My application has tables with timestamp columns. When the application wants to update a record he questions the recording (and part of the record is the time it has been updated), changes the record and trying to engage. If the user spends an hour of last updated with it's update request. A stored procedure will check the current value of the lastUpdateTime of this record by doing a query on this line and compare this value with the one that the user provided in the update request.

Given that the installer, if my failover database is in a different time zone and traffic is automatically routed to the backup site, these comparisons are going to fail? They will fail only depending on whether I'm using CURRENT_TIMESTAMP vs SYSTIMESTAMP? No matter if the column is of type Timestamp which factors in the zone or not? Do I need to have both systems to be set to the same time zone (UTC, for example)? I'm afraid that even if I record it without time zone info, Oracle will try and automatically transform the time somehow. Perhaps my concern is not justified.

Thank you.

Here is the difference

The current_timestamp function returns the date and time in the current time zone of the SQL session as prepared by the ALTER SESSION command. It returns a value of TIMESTAMP WITH time ZONE SCHEDULE.

The systimestamp function returns the date current system and time (including fractions of a second and the time zone) on your local database.

If your application needs to update by using the time zone of the date.

  • How to calculate time zones

    "hours = mydate.getHours () - 2; So, if it's 2:00 central it is 12:00 in the Pacific. Do my method will show it's midnight when it is not. How can I fix? Thanks in advance. Here is my code. I hope that with a correction, I can do the same for other time zones.

  • Necessary to define the database time zone differs from the OS

    We have a database of who currently resides in New York. Let's move to another server that resides in London. This is a problem, because each date which is currently in the time base is New York time, but after the move, all the new data that created time will always be time to London. We do not want users to have to remind any date preceding the date of move, will idle 5 hours if we would like to do is to have the database always on time in New York despite the BONE being London time. The server will be shared with other applications for the operating system time zone will have to remain with London time. The database will only have data for our application. So is there a setting of database that we can use to set the time zone database is different from the operating system time zone? The database is currently 10 GB but is promoted as part of the move to 11 g.

    What is the data type of the column? If the date or timestamp, then there is no time zone stored with the data. If timestamp with time zone, then the time zone of the data remains the same regardless of the time zone database and operating systems.

  • How to configure a FTP server and the web and integrate with 5.2 DMM

    Hi all...

    I need to set up an external server only for publishing content to reduce the overhead of the DMM server.

    can someone guide me on how to configure the external server and it intergrate with the DMM 5.2

    Thank you

    semuthu,


    Notes from the Release Notes:


    Limitations of compatibility with Microsoft Internet Information Server (IIS)

    DMP who use firmware version 5.2 is compatible with a single version of Microsoft Internet Information Server.

    This supported version is IIS 6.0 for Windows 2003 Enterprise Edition. If you do not have the support for IIS version but

    want your DMP to recover the assets of a Web server, we recommend that you use Apache instead of IIS.



    I suggest to use Apache instead of IIS for the Web Server service. IIS can be used as FTP if necessary.

    There are a lot of Documents on the Internet concerning the implementation of Apache and FTP servers.

  • How to change time zone on VMHost

    Hey all

    I'm running out of ideas, doesn't know it's so hard to find how configure/update the time zone on the ESX host using powercli

    Thanks for your advice much appreciated!

    Cheers, Rafael

    You can specify the name of the $vmhost instead of the real object, which is called the characteristic of the object by name (OBN).

    The problem is that the $host variable is an internal variable used by PowerShell.

    Choose a different name for the variable, and it will work.

  • How to adjust time settings manually on the endpoints of TC

    Hello

    We have endpoints of TC TC7.3.2 running. We have NTP and already set to OFF. We want to set the time manually using the clock buit - in the codec. How can adjust the time manually. On the web interface, I see on the time settings to set the timing of the hours/minutes. Is there a command on the API to do this?

    Appreciate for your help.

    Thank you in advance.

    If endpoints using the touchscreen device, you should be able to adjust the settings of the time on the touch screen. Make sure that UserPreferences is set to this setting is available on the touch device and access the setting.

    Accessing the web interface Configuration > System Configuration > UserInterface > UserPreferences: on

    On the touch screen, browse on settings > administrator > admin settings > Date, time & location

    From there you should be able to set the clock manually synchronised.
