v$session + v$session_wait (在10g裡功能被整合,湊合算1個吧.)
v$process
v$sql
v$sqltext
v$bh (更寧願是x$bh)
v$lock
v$latch_children
v$sysstat
v$system_event
按組分的幾組重要的性能視圖
1。System 的 over vIEw
v$sysstat , v$system_event , v$parameter
2。某個session 的當前情況
v$process , v$session , v$session_wait ,v$session_event , v$sesstat
3。SQL 的情況
v$sql , v$sqlarea , v$SQL_PLAN , V$SQL_PLAN_STATISTICS, v$sqltext_with_newlines
3. Latch / lock /ENQUEUE
v$latch , v$latch_children , v$latch_holder , v$lock ,V$ENQUEUE_STAT ,V$ENQUEUE_LOCK
4. IO 方面的
v$segstat , v$filestat , v$tempstat ,v$datafile , v$tempfile
5.shared pool / Library cache
v$Librarycache , v$rowcache , x$ksmsp
6.幾個advice也不錯
v$db_cache_advice , v$PGA_TARGET_ADVICE, v$SHARED_POOL_ADVICE
