Login Dialog : "The database has not been configured to run background jobs..."

Hello to all,

I am trying to find out why a certain dialog box appears right after I login to P6.  

So, the P6 "Login to Primavera P6" dialog box comes up on starting the program.  I plug in my password, and the the login dialog box title changes to "Connecting to database...", then "Validating user...", then this is when I get a "Primavera P6" dialog box with the following text and an "OK" button: Can someone 1) explain what this means, and 2) how it can be resolved?  

Thanks in advance for your help!
