Need Your Help on Database connection

Hi and good day,

     I have 7 different PB applications running and each one uses its own DB
 connection...

     But in some point too many users are already using all applications in 
one PC and i dont have any connections left for the rest of the users....


     I was just wondering if it is possible that i can run all 7 application
s together in one computer making use of only one database connection.

     I cannot afford to merge all applications into one application, coz it 
will take me forever to compile....

     Hope you can give ideas...appreciate that a lot...

thanks,

Jimboy
