The Connect function will always validate and save the DBCAREA options, regardless of the Change-options. The options remain in effect until another Connect function is requested or the values are changed when an Initiate Request, Initiate With Protocol-function, or RunStartUp function call is made (Change-options = Y).
Implicit logon processing will also always validate and save the DBCAREA options. For more information, see Implicitly Establishing a Session.
