Finding statement/s which use lots of shared pool memory

SELECT substr(sql_text,1,40) "Stmt", 
count(*),
sum(sharable_mem) "Mem",
sum(users_opening)   "Open",
sum(executions)      "Exec"
FROM v$sql
GROUP BY substr(sql_text,1,40)
HAVING sum(sharable_mem) > ;


MEMSIZE is about 10% of the shared pool size in bytes
