You should validate the .st file online before adding extents to your database. To do so, you use the PROSTRCT ADDONLINE VALIDATE utility.

The command to validate a .st file online is:
prostrct addonline db-name .st-file –validate

Assume you have a .st file, sports_add.st, that adds two fixed extents and a variable extent to the sports database. Also assume that the sports database is running.

To validate sports_add.st online, enter:
prostrct addonline sports sports_add.st –validate
