Mac 電腦虛擬機 Parallels 中進行Oracle 12.2.0.1 數據庫軟件安裝時，預環境檢查過程中，提示堆棧大小限制[失敗]，即使修復問題依然如故。
Oracle 12.2.0.1 Installation Fails With "PRVG-0449 : Proper soft limit for maximum stack size was not found on node "node1" [Expected >= "10240" ; Found = "8192"]" (文檔 ID 2287806.1)
在MOS文檔中提到：是一個未發布的Bug（Unpublished bug 25039206），截至2019年5月26日依然未發布。
問題：
Soft Limit: maximum stack size - This is a prerequisite condition to test whether the soft limit for maximum stack size is set correctly. Details: PRVG-0449 : Proper soft limit for maximum stack size was not found on node "henry" [Expected >= "10240" ; Found = "8192"]. - Cause: The Cluster Verification Utility determined that the setting for the indicated soft limit did not meet Oracle''s recommendations for proper operation on the indicated nodes. - Action: Modify the resource limits to meet the requirement and take operating system specific measures to ensure that the corrected value takes effect for the current user before retrying this check.
解決方案：runfixup.sh 運行后，虛擬機退出（取消）當前安裝程序，重啟虛擬機后，再次運行 ./runInstaller ，預環境檢查通過。
官方建議：
The sessions needs to be relaunched for the fix-ups to be effective. For example, if it is a VNC sessions then the user has to close it and Re-Login to create a new session where the new stack limits will be loaded.
備注：
Note : This bug is fixed in the upcoming release of database software.
