    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。
