NNO-00257: warning: cannot get serial number from region store

NNO-00257: warning: cannot get serial number from region store
Cause: The server encountered an error while trying to get the configuration database's serial number. The error occurs almost always because time the server is unable to access the configuration database. If the error occurs during server startup, the server will shut down. If the error occurs during server operation (the server checks the serial number periodically to see if it should reload itself), then the server assumes a transient failure has occurred and repeats the operation a short while later. If the repetitions continue to fail for three days, the server will log another error and stop issuing the serial number load operation.
Action: First make sure that the Netadmin program has exported a server configuration for this name server. Next, make sure that the database is running, that its name and password as specified in the Oracle Network Manager are accurate, and that there is SQL*Net connectivity between the Oracle Names server and the database. If the error occurs during server startup, you can force startup anyway, with checkpoint data, by starting the server with the names.no_region_database parameter set to TRUE. If no checkpoint data is available, the server will shut down.

NNO-00257：警告：无法从区域存储获取序列号,
.原因：服务器在尝试获取配置数据库的序列号时遇到错误。错误发生几乎总是因为服务器无法访问配置数据库的时间。如果在服务器启动期间发生错误，服务器将关闭。如果在服务器运行期间发生错误（服务器定期检查序列号，看是否需要自行重新加载），那么服务器假设发生了瞬时故障，并在短时间内重复操作。如果重复持续三天失败，服务器将记录另一个错误，并停止发出序列号加载操作。,
.操作：首先确保Netadmin程序已导出此名称服务器的服务器配置。接下来，确保数据库正在运行，其在Oracle网络管理器中指定的名称和密码是准确的，并且Oracle Names服务器和数据库之间存在SQL * Net连接。如果在服务器启动期间发生错误，您可以通过启动服务器，将names.no_region_database参数设置为TRUE来强制启动检查点数据。如果没有检查点数据可用，服务器将关闭。,
