按組分的幾組重要的性能視圖
1。System 的 over view v$sysstat , v$system_event , v$parameter
2。某個(gè)session 的當(dāng)前情況 v$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$ksmsp
6.幾個(gè)advice也不錯(cuò) v$db_cache_advice , v$PGA_TARGET_ADVICE, v$SHARED_POOL_ADVICE
