We can use below query to check the session details.

 Query:


 select s.ECID ,s.inst_id, s.SID,s.SERIAL#,p.spid,s.status,s.machine, s.ACTION, s.MODULE, s.TERMINAL,s.sql_id,s.last_call_et,s.event, s.client_info,s.PLSQL_SUBPROGRAM_ID,s.PROGRAM,s.client_identifier
, ( SELECT max( substr( sql_text , 1, 40 )) FROM gv$sql sq WHERE sq.sql_id = s.sql_id ) AS sql_text
, ( SELECT object_name FROM dba_procedures WHERE object_id = plsql_entry_object_id AND subprogram_id = 0) AS plsql_entry_object
, ( SELECT procedure_name FROM dba_procedures WHERE object_id = plsql_entry_object_id AND subprogram_id = plsql_entry_subprogram_id) AS plsql_entry_subprogram
, ( SELECT object_name FROM dba_procedures WHERE object_id = plsql_object_id AND subprogram_id = 0) AS plsql_entry_object
, ( SELECT procedure_name FROM dba_procedures WHERE object_id = plsql_object_id AND subprogram_id = PLSQL_SUBPROGRAM_ID) AS plsql_entry_subprogram
, 'alter system kill session ' || '''' || s.SID || ',' || s.serial# ||',@'|| s.inst_id||''''|| ' immediate;' kill_session
from gv$session s ,gv$process p
where
--client_identifier like '%HIMANSHU.SINGH%'
--s.ecid like '%ZnHWOPoUDWbG%'
-- sid=4361
--p.spid='1196'
--s.program like '%ICM%'
and p.addr=s.paddr
and p.inst_id = s.inst_id
;
Note: Un-comment the condition which ever is required.
