Use the WITH EXPRESS CHECK option when validating tables

If you find that validating large databases with a small cache takes a long time, you can use one of two options to reduce the amount of time it takes. Using the WITH EXPRESS CHECK option with the VALIDATE TABLE statement, or the -fx option with the Validation utility can significantly increase the speed at which your tables validate.
