4.Load the data store from the file using ttMigrate with the

-noCharsetConversioncommand line option. This option ensures that no character values are changed when the data is loaded into the DSN using the new character set. For example:

ttMigrate -r -noCharsetConversion

DSN=SalesData salesdata.mig

Note: If you find that you have accidentally converted your data store from TIMESTEN8 to the wrong character set, you can use the same procedure to convert your data store to the correct character set without any accidental modification of the character data.

Converting from a character set other than TIMESTEN8

You may use ttMigrate to convert a data store from any character set to any other character set by completing the following steps:

1.Save the data store to a file using ttMigrate. For example, to save the data store SalesData to the file salesdata.mig, use the command:

ttMigrate -c DSN=SalesData salesdata.mig

2.Destroy the data store: ttDestroy SalesData

3.Change the value of the DSN attribute DatabaseCharacterSet for your data store to the value specifying the new character set. For example, if you want your data store to use the WE8ISO8859P1 character set, use the following line in your ODBCINI file:

DatabaseCharacterSet=WE8ISO8859P1

4.Load the data store from the file using ttMigrate. TimesTen will automatically convert the character data from the character set the file was saved with to the character set used by the DSN. For example:

ttMigrate -r DSN=SalesData salesdata.mig

Note: It is possible that character data will be lost in the conversion process if no mapping exists from one character set to the other for a given character.
