The computing industry standard known as Unicode handles text expressed in most of the world’s writing systems. UTC (Coordinated
Universal Time) is the primary time standard by which the world regulates clocks. It does not observe daylight saving time.
This procedure updates a database to support Unicode and UTC.
Prerequisites: Before connecting to your database for the first time you enabled Use Unicode Encoding Scheme.
- Back up the database(s) to update.
CAUTION: This Unicode and UTC upgrade procedure is one-way only and cannot be reversed. It is highly recommended that you back up the
database(s) prior to running the wizard.
- Right-click the RdbmsNetwork node in the Nav tree and click Update Wizard
The Database Update Wizard window opens to the the Select Update Procedures window.
- Enable one or both properties and click Next.
The wizard displays one or more databases to be updated to Unicode.
- Select the database(s) to update to Unicode and click Next.
The wizard completes the update and displays the results for review.
- To continue, click Next.
If you enabled both options, the wizard displays one or more databases to be updated to UTC.
- Select the database(s) to update to UTC and click Next.
If you updated UTC, the wizard opens the Timezone Update — Timestamp Storage Policy view.
- To define the storage policy, select one or the other of the options and click Next.
The wizard completes the update and displays the results for review.
- To complete the update, click Finish.
If you updated to Unicode, the wizard automatically sets the
Use Unicode Encoding Scheme property on the database
Property Sheet to
true.
If you updated to UTC, the wizard automatically sets the Timestamp Storage property on the database Property Sheet to true and sets this property to read-only. To make Timestamp Storage writable again, right-click the database device and click .
When the procedures and databases have been specified in the Update Wizard, the updates are submitted as jobs to the Job Service.
The Update Wizard processes the database tables and changes the data types of string-valued columns to the NVARCHAR data types
and adjusts the database timestamps to UTC time. The wizard provides visibility on the progress of individual jobs. At a later
stage, you can view the jobs in the Job Service. The update operations either complete entirely or roll back entirely if any
error occurs.
