一起数据库服务器故障引发调度命令模块异常的处理

Handle Abnormity of Dispatching Command Module Caused by Database Server Fault

针对南宁铁路局Oracle数据库服务器A机无法对外提供服务但网络连接是正常状态,同时服务器B机未能正常接管RAC集群服务故障的具体现象,对原因及处理方法进行阐述;最终将VOTEDISK(表决盘)数量增加为奇数,并将Oracle客户端由顺序选择连接模式调整为负载均衡模式,使故障得以消除。对Oracle数据库类似故障处理具有一定参考意义。

As far as the phenomenon that the Oracle database server A could not provide services but its network connection was normal and the server B failed to take over the RAC cluster serv- ice as normal is concerned, the reason and disposal method of the failure is explained. By increas ing the number of VOTEDISK to an odd number and adjusting the sequential selection connection mode of the Oracle client to a load balancing mode, the failure can be eliminated, offering certain reference for similar fault handling of Oracle database.
