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.
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.
