IBM

Question

环境：

1. 6.2.0.0消费者版
2. 自由8.5.5.1
3. IBM DB2
4. Windows2008Server
5. iPhone 5- IOS 7
6. 基于适配器的认证

Worklight服务器的两个节点指向一个DB2实例。

当我尝试登录时，会经常提示直接更新。但我的设备上正在运行更新版本。

即使我继续进行更新，设备生成也回滚到以前的版本。

在某些设备提示更新之后，这一次新版本已经更新。

我有下面的日志。

这是因为两个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。

Answer 1

这可能是因为您正在使用两个独立的Libery应用服务器，它们都指向同一个数据库。

因为它们是独立的，所以当发生直接更新时，它们不会得到“同步”。

若要启用此同步，应用程序服务器必须部署为服务器群。

有关服务器场的详细信息，请参阅下列文档主题：为Worklight server管理定义服务器场
