mac下navicate連接oracle報ORA-21561: OID generation failed錯誤 或者 hostname is not set

Navicat連接了Oracle數據庫

測試連接失敗，提示：hostname required

解決：

在終端下查看本機：    hostname

➜  ~ hostname
skdeMacBook-Pro.local

➜  ~ cat /etc/hosts

➜  ~ cat /etc/hosts
##
# 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  

 發現hostname不一致，執行如下命令

➜  ~ sudo scutil --set HostName localhost

再次連接，問題解決
