EVENT: 10060 dump predicates in optimizer (kko)

Event:10060
Text:   dump predicates in optimizer (kko)
-------------------------------------------------------------------------------

Explanation:
        This is a special EVENT code.
        It should *NOT* be used unless explicitly requested by ST support.

        This event can be useful in conjunction with an explain plan
        to confirm which operations occur where in the execution plan.
        It dumps the predicates into a special table.

Usage:
        - Available in 7.1.3 onwards when using CBO
        - NOTE: This does NOT do anything under RULE

        - After 7.1.3 you must create a special table called
          "kkoipt_table" before you set the event. This table should be
          in the schema of the person running under event 10060.
    
            create table kkoipt_table (
                    c1 integer, c2 varchar2(80)
            );            

        - To enable tracing:
            ALTER session set events '10060 trace name context forever';

        - Run the statement to be traced

        - Set formatting:
          set pages 999
          column c1 format 990
          column c2 format a75

        - select * from KKOIPT_TABLE;

        - Best used in conjunction with <Event:10053> trace and an
          execution plan.

Example:
~~~~~~~
select a.* from memp a, memp b
where a.sal > 5050 and rownum < 4 and 1=1
  and a.empno (+) = b.empno;

Output: (from kkoipt_table)

         1 fptrnum
         2  4>ROWNUM
         3 Table:
         4 MEMP
         5 frofand
         6  "A"."SAL">5050
         7 Table:
         8 MEMP
         9 frofand
        10  "A"."EMPNO"="B"."EMPNO"
