Ultimate Guide to Oracle Time Configuration for Efficient and Reliable Performance（oracle时间设置）
As an IT professional, a basic understanding of Oracle’s time conventions and globalization settings is essential for efficient and reliable performance of your database infrastructure. Oracle provides a wealth of resources for managing, configuring and optimizing the database environment to best suit your particular requirements. In this ultimate guide, we will provide a step-by-step guide to configuring Oracle database times and globalization settings for optimal performance.
Oracle provides a rich set of tools for managing the server time, which is called the Oracle Time Zone File. This file contains all the time zone information that Oracle needs to properly interpret date and time values, and also has fields for daylight savings and other regional preferences. By default, the Oracle Time Zone File contains a very large set of time zone definitions, so it’s important to ensure that your system is configured to use the correct values.
The Oracle time zone file is configured in the database using the Globalization Support files, which are stored in the Oracle Home directory. The Globalization Support files contain information about the time zone offsets, time formats, language codes, and other time-related settings.
To configure the Globalization Support files, launch the Oracle Universal Installer, which can be found in the Oracle Home directory. Under the Database Configuration tab, select “Globalization Support.” Here you can select the time zone from the list of available time zones and save your changes.
Once you’ve configured the Globalization Support files, you’ll need to synchronize the system time with the Oracle database. This can be done by manually setting the system clock or by enabling the automatic synchronization feature in Oracle. If you choose to enable the automatic synchronization feature, make sure to set the appropriate system time zone in the Administrative Tools panel.
Finally, to ensure that the Oracle database is using the correct time zone and globalization settings, you can run a query against the database. You can use the query below to confirm that the correct time zone is being used:
SELECT date_zone FROM global_name WHERE date_zone = ‘YOUR_TIME_ZONE’;
By following these steps, you’ll be able to configure Oracle’s time settings for efficient and reliable performance of your database infrastructure. It’s also important to keep the system clock in sync with the Oracle database so that your applications and queries run accurately. Using the above guide, you should now have a basic understanding of how to configure Oracle’s time settings and make sure that your database is running optimally.
