昨天一台PC Server上的数据库又出问题，同样是硬盘故障。
这两台服务器用的都是联志的国产低端PC Server，这些服务器的质量实在是差，上次一台备机的硬盘损坏，然后又有一台因为电源模块的问题反复重起，现在这一台服务器的硬盘再次出现问题。

好在数据库通过DataGuard可以切换到另外一台，没有数据损失：

现在是主库所在的服务器出现问题:
SQL> select dbid,name,PROTECTION_MODE,DATABASE_ROLE,SWITCHOVER_STATUS from v$database;
DBID NAME PROTECTION_MODE DATABASE_ROLE SWITCHOVER_STATUS
---------- --------- -------------------- ---------------- ------------------
3520694939 BMARK MAXIMUM PERFORMANCE PRIMARY SESSIONS ACTIVE
备库现在一切正常:
SQL> select dbid,name,PROTECTION_MODE,DATABASE_ROLE,SWITCHOVER_STATUS from v$database;
DBID NAME PROTECTION_MODE DATABASE_ROLE SWITCHOVER_STATUS
---------- --------- -------------------- ---------------- ------------------
3520694939 BMARK MAXIMUM PERFORMANCE PHYSICAL STANDBY SESSIONS ACTIVE
现在需要的是一点停机时间进行切换。

The primary database controlfile was created using the
'MAXLOGFILES 5' clause.
The resulting standby controlfile will not have enough
available logfile entries to support an adequate number
of standby redo logfiles. Consider re-creating the
primary controlfile using 'MAXLOGFILES 8' (or larger).
Use the following SQL commands on the standby database to create
standby redo logfiles that match the primary database:
ALTER DATABASE ADD STANDBY LOGFILE 'srl1.f' SIZE 10485760;
ALTER DATABASE ADD STANDBY LOGFILE 'srl2.f' SIZE 10485760;
