oracle dba常用到的动态视图

v$session + v$session_wait (在10g里功能被整合,凑合算1个吧.) v$process  v$sql v$sqltext v$bh (更宁愿是x$bh) v$lock v$latch_children v$sysstat v$system_event  按组分的几组重要的性能视图 1。System 的 over view v$sysstat , v$system_event , v$parameter 2。某个session 的当前情况 v$process , v$session , v$session_wait ,v$session_event , v$sesstat 3。SQL 的情况 v$sql , v$sqlarea , v$SQL_PLAN , V$SQL_PLAN_STATISTICS, v$sqltext_with_newlines 4. Latch / lock /ENQUEUE v$latch , v$latch_children , v$latch_holder , v$lock ,V$ENQUEUE_STAT ,V$ENQUEUE_LOCK 5. IO 方面的 v$segstat , v$filestat , v$tempstat ,v$datafile , v$tempfile 6.shared pool / Library cache v$Librarycache , v$rowcache , x$ksmsp 7.几个advice也不错 v$db_cache_advice , v$PGA_TARGET_ADVICE, v$SHARED_POOL_ADVICE
