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
sudo scutil --set HostName localhost
- 重新连接 Oracle
