Certificates created through the VersaLex application have a default validity period of 24 months. This validity period can range from 1 to 96 months and can be lengthened or shortened as necessary when creating a new certificate. After that time, your certificate is no longer considered valid and you should generate a new certificate and distribute it to all your trading partners.
Beginning 30 days prior to a certificate’s expiration date, the VersaLex application logs warning notifications in its message log when any certificates used by the application (that is, either your user certificates or your trading partners' certificates) are about to expire or have already expired.
You can also set the Email Local Certificate Expiration Notices property in the Local Listener: Advanced tab to receive daily email notifications when any of your user certificates is within 30 days of expiration or have already expired. See Specifying Local Listener advanced properties. Otherwise, if the Email Local Certificate Expiration Notices property is not set and you have System Event logging configured for both errors and warnings (applies to the Cleo Harmony and Cleo VLTrader applications only), the daily certificate expiration notifications are logged in the System Event log/file instead. If the Email Local Certificate Expiration Notices property is not configured and System Event logging is not defined, a warning message is logged in the VersaLex message log if it detects any local or partner certificates have expired or are about to expire. See Logs.
Although a 30-day warning should afford you ample time to either generate a new certificate and distribute it to all your trading partners or request and obtain a new certificate from your trading partner, you may change this default setting by changing the Email Local And Partner Certificate Expiration Warning Days property in the Local Listener: Advanced Tab. See Specifying Local Listener advanced properties.
