Mac 电脑虚拟机 Parallels 中进行Oracle 12.2.0.1 数据库软件安装时，预环境检查过程中，提示堆栈大小限制[失败]，即使修复问题依然如故。
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"]" (文档 ID 2287806.1)
在MOS文档中提到：是一个未发布的Bug（Unpublished bug 25039206），截至2019年5月26日依然未发布。
问题：
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.
解决方案：runfixup.sh 运行后，虚拟机退出（取消）当前安装程序，重启虚拟机后，再次运行 ./runInstaller ，预环境检查通过。
官方建议：
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.
备注：
Note : This bug is fixed in the upcoming release of database software.
