 [Sub Heap Dump]
 alter session set events \'immediate heapdump_addr (address=n [, level = 2])\';
 n はサブ・ヒープ ds のアドレスとなります。

 1. ds フィールドの値を見ます。
 2. 値を 10 進数（ decimal ）に直します。
 3. HEAPDUMP_ADDR イベントの address パラメータに、その値を指定します。
 4. チャンクの内容をダンプする (with contents) には、 2 以上のレベルを指定します。

[Library Cache Dump]

 alter session set events \'immediate library_cache (n)\';

 Level 1:        ライブラリ･キャッシュ統計
 Level 2:        ハッシュ･テーブルのサマリ
 Level 4:        各 LCO の Partial 情報 ( オブジェクト・ハンドル )
 Level 8:        各 LCO の More 情報 ( オブジェクト・ハンドル + ヒープ 0)
 Level 16:        各 LCO の Most 情報 ( オブジェクト・ハンドル +ヒープ 0+ 子カーソル)
 Level 32:        ヒープ ･ダンプを 追加 ( レベル 8,16 との組み合わせで使用 )
 Level 64:        子カーソルの情報を追加 ( レベル 4 または 8 との組み合わせで使用 )
 Level 2048:        ダンプ時に LCO の Mutex を獲得しない
 Level 8192:        各 LCO の Least 情報 ( オブジェクト・ハンドルの一部 )

[System State Dump]

 alter session set events \'immediate systemstate (n)\';

 Level 1            Very basic process information only
 Level 10        Most common level - includes state object trees for all processes.
                 Includes "interesting" RAC resources in the trace (in RAC only).
 Level 11        In RAC level 11 includes a dump of any resources not on the freelist
                 just after the "BUSY GLOBAL CACHE ELEMENTS" section.
 Level + 256        Adding 256 to the level will try to dump short stack info for each
                 process when the enhancement described in Note:3797523.8 is present.
                 *** IMPORTANT ***
                 Short stacks are produced reasonably quickly on Solaris and Linux but
                 on other platforms including short stacks in dumps can take a very
                 long time. Hence it is advisable to test if the overhead is acceptable
                 before using this option.


 [All Node System State Dump on RAC]
 alter session set events \'immediate systemstate_global (11)\';

[Hang Analyze]

 alter session set events \'immediate hanganalyze (n)\';

 Level 1            Very minimal output
 Level 2            Minimal output
 Level 3            Dump only processes thought to be in a hang <<< Most common level
 Level 4            Dump leaf nodes in wait chains
 Level 5            Dump all processes involved in wait chains (can be a lot)
 Level 6            Dump errorstacks of processes involved in wait chains (can be high overhead)
 Level 10        Dump all processes (not a good idea)
