解决 ORA-21561: OID generation failed

昨天更新了macOS Sierra 后,发现用 Navicat 连接 Oracle 报 ORA-21561: OID generation failed 错误

解决方法

  • 打开终端,查看 hostname
hostname

发现是 local 而不是 localhost

  • 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 
  • 问题已经找到了,因为 hostname 和 hosts 文件里的 hostname 不一致
  • 解决办法,修改 hostname 与 hosts 里保持一致
sudo scutil --set HostName localhost
  • 重新连接 Oracle
