[20210528]Oracle 19c Max_Idle_Blocker_Time Parameter.txt

[20210528]Oracle 19c Max_Idle_Blocker_Time Parameter.txt

This parameter differs from the MAX_IDLE_TIME parameter in that MAX_IDLE_TIME applies to all sessions (blocking and
non-blocking), whereas MAX_IDLE_BLOCKERG_TIME applies only to blocking sessions. Therefore, in order for
MAX_IDLE_BLOCKING_TIME to be effective, its limit must be less than the MAX_IDLE_TIME limit.

And the MAX_IDLE_TIME limit parameter is available from 12.2.0.1 version.

--//不知道是否有用,這樣可以不用解決問題,交給資料庫自己解決.做一個記錄.不過我感覺不好用。
