错误提示 “To view this page ensure that Adobe Flash Player version 11.5.0 or greater is installed. “。登陆框依旧可见，但是登陆后页面成空白状。
You may see that error message “To view this page ensure that Adobe Flash Player version 11.5.0 or greater is installed. ” when you open vSphere Web Client 6.0 on IE 11 on Windows 8.1. The login fields still visible, but the page go to blank after you login.
某日，vCenter Server突然无法搜索虚拟机了。在vSphere Client中搜索时会提示 Unable to connect to web services to execute query. Verify that the ‘VMware VirtualCenter Management Webservices’ service is running on https://vCenter_Server_FQDN:10443。没过几个小时用户就开始抱怨vSphere Web Client也出问题了，总是提示错误 Client is not authenticated to VMware Inventory Service – https://Inventory_Service_FQDN:10443。
Best practices to manage enterprise Active Directory is organizing servers by particular properties. For example, servers maybe put into different OU by role, business group or function…etc. Following is a vRO workflow sample to automate provisioning computers in proper OUs according to user choice in vRA Service Catalog. I’ll just give brief of each step in this article, so please make sure you understand both products before read this post.
当创建虚拟机的时候你可能需要将虚拟机根据不同的属性放入不同的OU中，比如根据角色、组、用户组等。在vRealize Automation Center (vRA)中可以很轻易地创建一个下拉菜单实现这类属性的选择，但是这类属性的值往往都以字符串的形式传递到vRO中，而vRO的活动目录工作流中并没有提供字符串转OU对象的功能。
When you put virtual machine to particular OU, you may refer to virtual machine properties, such as ‘server role’, ‘server group’ or ‘user group’…etc. It’s easy to set a drop-list in blueprint of vRealize Automation Center (vRA) to let users choose this kind of properties but hard to create a computer account in corresponded OU location in vRO. That’s because vRA passes most of values to vRO as strings, Active Directory workflows in vRO do not provide a way to convert string to OU.
One day, my vCenter Server suddenly lost search. It popped me “Unable to connect to web services to execute query. Verify that the ‘VMware VirtualCenter Management Webservices’ service is running on https://vCenter_Server_FQDN:10443” when I did object search on vSphere Client. Few hours later people starting complaint they got error on vSphere Web Client, it show “Client is not authenticated to VMware Inventory Service – https://Inventory_Service_FQDN:10443“.
今天在vRealize Operation Manager 6.0创建了几个super metric，主要用来计算ESXi主机的物理链路吞吐量。结果发现这些super metric只是出现在部分主机里。估计是有什么bug。快速解决的办法是重启一下vROps vApp。
Today I created few super metrics on vRealize Operation Manager 6.0 to calculate throughput of physical links on ESXi host. The super metrics just present to part of the selected hosts. I guess it’s some kind of minor bug. A reboot of vROps vApp can works around it. Just heads up.
