Hi I have a shell script that i ran around noon yesterday which calls a sql script which contains a line dbms_utility.compile_schema . The pid of the shell script is something like 1429756 But when i do this ps -ef|grep 1429756 i get oracle 1429756 1 0 Mar 16 - 0:00 sh -- ./script.ksh oracle 2597014 1429756 0 Mar 16 - 0:00 sqlplus oracle 3002442 2297992 0 02:46:02 pts/6 0:00 grep 1429756 However for the spid 2597014 i dont see any activity in v$session. How do i go about tracing this session inside oracle database ?
