Simple Mode Certificate Duration
By default Oracle COREid simple mode certificates are issued for 1 year (365 days) by default.
If you would prefer a different expiration time you can change the setting that controls the certificate’s duration. There are two files that control the duration, each is used depending on the certificate (re)generation situation. I think it is best to just change both files to cover your bases.
The paramater to change is “default days”…
default_days= 365# Duration to certify for
Change this to the desired number and regenerate your simple mode certificate.
