Oracle 9i historical long queries since instance startup
Dynamic performance views are not guaranteed to have all SQL information since instance startup because of the limited amount of memory.

Oracle 9i does not have AWR.

You can use Statspack, but it is not installed by default.

Install it as SYSDBA with:

@?/rdbms/admin/spcreate

Creating a snapshot (does not happen automatically, this needs to be scheduled manually or with spauto.sql):

EXECUTE statspack.snap;

Creating a report:

@?/rdbms/admin/spreport
