Where do I find DBMS_STATS procedures?

Question

I am just beginning the preinstall section for the Oracle 9.2.0.6 patch set and they indicate that I should run the following procedures (scripts?)":
SQL> DBMS_STATS.DELETE_SCHEMA_STATS('SYS');
SQL> DBMS_STATS.GATHER_SCHEMA_STATS('SYS');
This is to clear out stats before the upgrade so that I won't be waiting while the install pointlessly goes through the SYS table. But when I tried to execute the first command above, all I got was this:
SQL> DBMS_STATS.DELETE_SCHEMA_STATS('SYS');
SP2-0734: unknown command beginning "DBMS_STATS..." - rest of line ignored.
Are DBMS_STATS procedures distinct from the base Oracle DB install? Do I need to grab another package to get them?

Answer 1

Either execute each procedure one by one
exec DBMS_STATS.DELETE_SCHEMA_STATS('SYS');
exec DBMS_STATS.GATHER_SCHEMA_STATS('SYS');or put them in an anonymous block
begin
   DBMS_STATS.DELETE_SCHEMA_STATS('SYS');
   DBMS_STATS.GATHER_SCHEMA_STATS('SYS');
end;
