解决ORA-21561
在linux上使用sqlplus连接oracle数据库
[root@china ~]# sqlplus test/test@ORCL SQL*Plus: Release 11.2.0.3.0 Production on Thu May 31 11:06:15 2018 Copyright (c) 1982, 2011, Oracle. All rights reserved. ERROR: ORA-21561: OID generation failed
解决过程
在终端上输入:~ hostname
china
查看/etc/hosts文件:~ cat /etc/hosts
127.0.0.1 localhost
保持hostname与hosts文件中127.0.0.1对应的名称一致即可!
[root@china ~]# cat /etc/hosts 127.0.0.1 china ::1 localhost localhost.localdomain localhost6
