Question:

I was experimenting with the extended password history for the first time. We want to clear out all of the passwords that were used during the testing process. How can this be done?

Solution:

The extended password history can be deleted one at a time, or done with a mass change. Here are some examples:

TSO ACF
SET PROFILE(USER) DIVISION(PASSWORD)
DELETE logonid <=== For one user
DELETE LIKE(-) <=== For ALL users
DELETE LIKE(A-) <=== For all users whose LOGONID begins with A

There should be no noticeable performance impact during this command process even though many profile records may be deleted with the DELETE LIKE(-) command.
