Although you are running with a purchased version of the server, there are one or more licenses registered that will expire on the date specified. This is usually the case when you have been using evaluation licenses prior to purchasing the product.
Server operation continues.
Halt the server and erase the nodelock file in the server startup directory. After restarting the server, use the REGISTER LICENSE command to define the licensed features that you have purchased with your server. These licenses should NOT have an expiration date, so this message should not appear after re-registering the proper licenses. If this message persists, contact your service representative.
