When installing Oracle 11g RAC, We need to configure the ntp service. There are many ways to configure the clock synchronization mode when using virtual machines. You can use the clock synchronization feature provided by vmware or directly use a local node as the time server.

Recently, in the process of building an Oracle RAC, DNS and NTP were needed, where DNS was used for domain names, IP management, and NTP for time synchronization. In fact, a long time ago to build these two services, but the technology, in essence, in line with the "use of waste back" objective law. The more you use it, the more skillful you will be. Less use even without, slowly forget. So that when the da
