ERROR at line 1:SQL> alter database open; #命令报如下错误
ORA-10458: standby database requires recovery
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/data/oracle/oradata/dg/system01.dbf'
主服务器日志如下：
tail -f /data/oracle/diag/rdbms/orcl/orcl/trace/alert_orcl.log
原因：可能为密码不一致相关，重新同步主服务器orapworcl 密码。
从服务器：
$cd /data/oracle/product/11.2.0/db_1/dbs/
$scp [email protected]:/data/oracle/product/11.2.0/db_1/dbs/orapworcl ./
#说明，上面ip为我服务器ip和路径，请根据实际情况修改，或用其他方式拷贝。
$cp orapworcl orapwdg
重新启动数据库：
ORACLE instance started.$sqlplus / as sysdba
