使用如下命令转储固定地址空间的内容：

alter session set events'immediate trace name heapdump_addr level 1, addr n';

以上计算的地址空间可以通过如下命令转储：

SQL> ALTER SESSIONSET EVENTS 'immediate trace name heapdump_addr level 1, addr 196033696';

Session altered.

获取转储文件的脚本：

SELECT a.VALUE || 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;

检查这个进程转储文件，可以发现如下Heap地址信息及空间分配：

由上面红色字体可见，在自动管理模式下，PGA,CGA,UGA都是独立分配的。
