客户的服务器启动不了em
报错Environment variable ORACLE_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name.
需要做的比对
1，oracle 目录下的TNS 、LSN配置文件hostname
2，linux /etc/hosts 里的hostname
3，oracle 用户下 .bash_profile 或者是 .bashrc
能配置hostname的地方是否都一致
我出现的问题是，用户改动过hostname , oracle 下的.bash_profile 申明的hostanme 和oracle 数据库的不一致所以报错，修改一致
source .bash_profile 可以使用
如果你确认hostname 和 sid 实例名都没有错
那么建议你进行emc重建操作
$ sqlplus / as sysdba
SQL> alter user dbsnmp identified by py123456;
User altered.
SQL> drop role MGMT_USER;
Role dropped.
SQL> drop user MGMT_VIEW cascade;
User dropped.
SQL> drop user sysman cascade;
User dropped.
SQL> drop user sysman cascade;
SQL> drop PUBLIC SYNONYM MGMT_TARGET_BLACKOUTS;
Synonym dropped.
SQL> drop public synonym SETEMVIEWUSERCONTEXT;
Synonym dropped.
SQL>quit
$ emca -config dbcontrol db -repos create
进行创建操作
