There was an unexpected server restart, after the restart i am not able to see the server pids.
i can see the sqlrule.llr and sqlrule.dfa in <BI_install_folder>\SAP Business Objects\SAP BusinessObjects Enterprise XI 4.0\win64_x64.
it was working before restart of server.
The DSN were configured with Windows Authentication, i changed them to DB username and Pwd.
i check the DSN's they are working fine.
i stopped SIA and restarted it still the serverpids and not coming up.
Thank you for the help !!!!!!!!
