在dataguard启用实时恢复的时候,报如下错误:
ORA-38500: USING CURRENT LOGFILE option not available without stand
实际操作:
SQL> alter database recover managed standby database using current logfile disconnect from session;
alter database recover managed standby database using current logfile disconnect from session
*
第 1 行出现错误:
ORA-38500: USING CURRENT LOGFILE option not available without stand
这个错误说明,在standby库没有standby logfile,在maxmize pretection,maxmize availability中必须
要有standby logfile,为了避免数据的损失最少,maxmize performance 也最好创建standby logfile,考虑角色切换
primary库也要创建standby logfile,
standby logfile创建的要求, 与primary的redo logfile的大小相同,个数要至少多一个
SQL> shutdown immeidate;
SP2-0717: 非法的 SHUTDOWN 选项
SQL> shutdown immediate;
ORA-01109: 数据库未打开
已经卸载数据库。
ORACLE 例程已经关闭。
SQL> startup mount;
ORACLE 例程已经启动。

现在,再启用实时应用, 就ok了!!!
SQL> alter database recover managed standby database using current logfile disconnect from session;
数据库已更改。
