以上是报错信息.
开始查错,
查到了TNS-12545: Connect failed because target host or object does not exist

网上查[TNS-12545: Connect failed] 找到tnsnames.ora文件
cat /opt/oracle/app/product/11.2.0/dbhome_1/network/admin/tnsnames.ora # tnsnames.ora Network Configuration File: /opt/oracle/app/product/11.2.0/dbhome_1/network/admin/tnsnames.ora # Generated by Oracle configuration tools. ORCL = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = oracle11)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl) ) )
看到:HOST = oracle11
查看我的hosts文件,真的没有这个:
[[email protected] ~]$ cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 [[email protected] ~]$
添加一条:
[[email protected] ~]$ su root Password: [[email protected] oracle]# echo "127.0.0.1 oracle11 " >> /etc/hosts [[email protected] oracle]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 127.0.0.1 oracle11 [[email protected] oracle]#
访问测试:,启动监听:
