mac连接数据库报错，ORA-21561OID generation failed

mac连接数据库报错，ORA-21561: OID generation failed

解决过程：

1. 打开终端,查看hostname

   hostname

   发现hostname是local而不是localhost

2. 查看hosts文件

   cd /etc
   open hosts

   内容为：

   ##
   # Host Database
   #
   # localhost is used to configure the loopback interface
   # when the system is booting.  Do not change this entry.
   ##
   127.0.0.1	localhost
   255.255.255.255	broadcasthost
   ::1             localhost
   # Added by Docker Desktop
   # To allow the same kube context to work on the host and the container:
   127.0.0.1 kubernetes.docker.internal
   # End of section

   hostname和hosts文件中不一致

3. 修改hostname和hosts保持一致

   sudo scutil --set HostName localhost
