When I log on to the Database using DBA Studio I see 12 active sessions . 1 is for DBA Studio and 11 of them are the background processes.

What are these background processes. Can u please list them?

Is their any significance for all the background processes to have the serial# as 1? What if the serial# for background processes 7 thro' 10 (and these processes do not specify any OS info or username or the program which it is using) are something other than 1? Is there something wrong with the database?

Thank you.
