环境：
Worklight Server的2个节点指向单个DB2实例。
我尝试登录时经常会提示直接更新。但是我的设备上运行了更新的版本。
即使我继续进行更新，设备构建也会回滚到之前的版本。
有些时候设备提示更新，这次新的构建已经更新。
我将以下内容作为日志。

这是因为Worklight实例指向同一个DB2吗？我相信情况并非如此。
帮助我解决回滚构建的问题。
答案 0 :(得分：0)
这可能会发生，因为您正在使用两个独立的Libery配置文件应用程序服务器，它们都指向同一个数据库。
因为他们是独立的，所以他们没有同步＆＃34;同步＆＃34;何时发生直接更新 要启用此同步，必须将应用程序服务器部署为服务器场。
有关服务器场的详细信息，请查看以下文档主题：Defining a server farm for Worklight Server administration
