    public database link vs  shared publicdatabase link

    972355
      Hello to all ;

      I know very well about public database link.
      I want to create shared public database link (two databases in same host).

      My question is

      How it is *( shared public database link )* different from public  database link ?

      Shared => what exactly it does between databases ?

      Thanks in advance ..

          Shared Database links enable multiple sessions on the source database to share the same connection to the target database, much like a 1:n relation that is present in an shared server configuration between server processes and user processes.

          They differ from regular DBLINKS in that way, Regular DBLINKS will create a connection on the target database for every session that uses the DBLINK on the source, it's a 1:1 relation.
