SELECT (1 - (phys.value / (db.value + cons.value))) * 100
'DB Block Buffer Cache Hit Ratio'
FROM v$sysstat phys,
v$sysstat db,
v$sysstat cons
WHERE phys.name = 'physical reads'
AND db.name = 'db block gets'
AND cons.name = 'consistent gets';

Hi,
"Oracle contains a set of underlying views that are maintained by the database server and accessible to the database administrator user SYS. These views are called dynamic performance views because they are continuously updated while a database is open and in use, and their contents relate primarily to performance."
SQL>select name from v$fixed_table;
you can query all dynamic views through above query.
regards
Taj
