Ensuring characters in database sets are supported in a Rational® ClearQuest® data code page
If you are using Rational® ClearQuest® for the first time, the GUI-based tools provide support to set up and manage data code pages for your schema repositories. Also, for many previous users of Rational ClearQuest whose data code pages were set to US-ASCII, the GUI provides all required code page functionality.

Ensuring characters in database sets are supported in a Rational® ClearQuest® data code page

If you are using Rational® ClearQuest® for the first time, the GUI-based tools provide support to set up and manage data code pages for your schema repositories. Also, for many previous users of Rational® ClearQuest® whose data code pages were set to US-ASCII, the GUI provides all required code page functionality.

In most cases, databases created by an older version of Rational® ClearQuest® are compatible with newer versions. In such a case, no action is required. However it is good practice to validate the database set by using the codepageutil utility to ensure that all existing data is compatible with the new data code page.

Some Rational® ClearQuest® environments will include data that must be converted before it can be used with an environment using a newer version. To convert your data, you must perform the following tasks:

Develop a conversion strategy for the data currently in your schema repositories.
Use the Rational® ClearQuest® utilities to evaluate your content and convert the data to the data code page that you plan to use.
