For example

    ALTER SESSION SET EVENTS
    '10013 trace name context forever, level 1';

Event 10015 - Dump Undo Segment Headers
This event can be used to dump undo segment headers before and after transaction recovery

For example

    ALTER SESSION SET EVENTS
    '10015 trace name context forever, level 1';

Event 10032 - Dump Sort Statistics
This event can be used to dump sort statistics. Level 10 is the most detailed

For example

    ALTER SESSION SET EVENTS
    '10032 trace name context forever, level 10';

Event 10033 - Dump Sort Intermediate Run Statistics
This event can be used to dump sort intermediate run statistics. Level 10 is the most detailed

For example

    ALTER SESSION SET EVENTS

For example

    ALTER SESSION SET EVENTS
    '10045 trace name context forever, level 1';

Event 10046 - Enable SQL Statement Trace
This event can be used to dump SQL statements executed by a session with execution plans and statistics. Bind variable and wait statistics can optionally be included. Level 12 is the most detailed.

For example

    ALTER SESSION SET EVENTS
    '10046 trace name context forever, level 12';

Levels are

Level Action
1 Print SQL statements, execution plans and execution statistics
4 As level 1 plus bind variables
8 As level 1 plus wait statistics
12 As level 1 plus bind variables and wait statistics



Event 10053 - Dump Optimizer Decisions
This event can be used to dump the decisions made by the optimizer when parsing a statement. Level 1 is the most detailed

    ALTER SESSION SET EVENTS
    '10053 trace name context forever, level 1';

Levels are

Level Action
1 Print statistics and computations
2 Print computations only



Event 10060 - Dump Predicates
This event can be used to force the optimizer to dump predicates to a table It is available in Oracle 7.1.3 and above, and was still working in Oracle 9.2.

This event requires the following table to be created in the schema of the user parsing the statement

    CREATE TABLE kkoipt_table
    (
        c1 INTEGER,
        c2 VARCHAR2(80)
    );

To enable this event use

    ALTER SESSION SET EVENTS
    '10060 trace name context forever, level 1';

This example uses the following object

    CREATE TABLE t1 (c01 NUMBER, c02 NUMBER);

With event 10060 set to level 1, when the following statement is executed for the first time

    SELECT c01 FROM t1 WHERE c02 = 0;

It is parsed and the results written to kkoipt_table

The results can be selected using the statement

    SELECT c1,c2 FROM kkoipt_table ORDER BY c1;

C1 C2
1 Table:
2 T1
3 frofand
4 "T1"."C02"=0



The following table summarises the various operations that can be reported by this event

Operation Description

我在数据库中设置了10081事件,然后在一个表中插入大量数据,high water mater应该会变大,为什么没有产生trace文件呢? 

Event 10081 - Trace High Water Mark Changes
This event can be used to trace high water mark changes

For example

    ALTER SESSION SET EVENTS
    '10081 trace name context forever, level 1';

[B]我在数据库中设置了10081事件,然后在一个表中插入大量数据,high water mater应该会变大,为什么没有产生trace文件呢? 

Event 10081 - Trace High Water Mark Changes
This event can be used to trace high water mark changes

For example

    ALTER SESSION SET EVENTS
    '10081 trace name context forever, level 1'; [/B]


hwm不一定会变大
你可以把segment的head dump出来看看。
