If we want to analyze execution plans on the SQL console, we probably need to find a SQL_ID first, which we can the pass to the DBMS_XPLAN.DISPLAY_CURSOR function. One way to find this SQL_ID is by querying the v$sql table first, e.g.:

SELECT   last_active_time,
         sql_id,
         child_number,
         sql_text
FROM     v$sql
WHERE    upper(sql_fulltext) LIKE '%SOME_SQL_TEXT%'
ORDER BY last_active_time DESC;

Now, often, you will then get an error message like:

ORA-00942: table or view does not exist

This simply means that you do not have the required privileges to select from that table. Have your DBA give you the required grant, or do it yourself on your local Oracle instance with:

C:\> sqlplus "/ as sysdba"

SQL> GRANT SELECT ANY DICTIONARY TO MY_USER;

Grant succeeded

Done. You can now query v$sql
