格式：
通过:符号，可以连续设置多个事件，也可以通过连续使用alter session set events来设置多个事件。
格式说明：
eventnumber指触发dump的事件号，事件号可以是Oracle错误号（出现相应错误时跟踪指定的事件）或oralce内部事件号，内部事件号在10000到10999之间，不能与immediate关键字同用。
immediate关键字表示命令发出后，立即将指定的结构dump到跟踪文件中，这个关键字只用在alter session语句中，并且不能与eventnumber、forever关键字同用。
trace name是关键字
eventname指事件名称（见后面），即要进行dump的实际结构名。若eventname为context，则指根据内部事件号进行跟踪。
forever关键字表示事件在实例或会话的周期内保持有效状态，不能与immediate同用。
level为事件级别关键字。但在dump错误栈(errorstack)时不存在级别。
levelnumber表示事件级别号，一般从1到10，1表示只dump结构头部信息，10表示dump结构的所有信息。

2、应用举例：
实际应用：
例：shutdown immdiate关闭数据库，然后在mount状态转储获得控制文件内容：
1、
SQL>starup mount;
SQL>alter session set events 'immediate trace name CONTROLF level 12';
2、get trc name：
|| b.symbol
|| c.instance_name
|| '_ora_'
|| d.spid
|| '.trc' trace_file
FROM (SELECT VALUE
FROM v$parameter
WHERE NAME = 'user_dump_dest') a,
(SELECT SUBSTR (VALUE, -6, 1) symbol
FROM v$parameter
WHERE NAME = 'user_dump_dest') b,
(SELECT instance_name
FROM v$instance) c,
(SELECT spid
FROM v$session s, v$process p, v$mystat m
WHERE s.paddr = p.addr AND s.SID = m.SID AND m.statistic# = 0) d
/
TRACE_FILE
