启动Physical Standby...

原创 Linux操作系统 作者:hoqingyuexiao 时间:2009-01-18 18:27:51 0 删除 编辑

今天突然被要求启动一个instance的standby,接到request之后脑子里迅速搜索相关知识,结果只有一些零散的命令片断...当时记得再劳的知识许久不用也光光啊

还有偶有online document这一法宝~打开10g的Data Guard Concepts and Administration,迅速定位到相关部分,按照步骤:

1. Start and mount the database:

SQL> startup mount;
ORACLE instance started.

Total System Global Area 2098693920 bytes
Fixed Size                   743200 bytes
Variable Size             520093696 bytes
Database Buffers         1577058304 bytes
Redo Buffers                 798720 bytes
ORA-01666: controlfile is for a standby database

2. Start log apply services:

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION
*
ERROR at line 1:
ORA-01507: database not mounted

其实第一步就有问题了,重来一遍还是如此,才发现此库乃9i的数据库,命令十有八九不对( ORA-01666错误其实就能说明问题了~)!

哈哈,还好9i的文档偶也有,迅速定位,follow:

1. Connect to the physical standby database instance.

sqlplus "/ as sysdba"

2. Start the Oracle instance at the physical standby database without mounting the database.

SQL> STARTUP NOMOUNT
ORACLE instance started.

Total System Global Area 2098693920 bytes
Fixed Size                   743200 bytes
Variable Size             520093696 bytes
Database Buffers         1577058304 bytes
Redo Buffers                 798720 bytes

3. Mount the physical standby database.

SQL> ALTER DATABASE MOUNT STANDBY DATABASE;

Database altered.

4. Start log apply services.

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;

Database altered.

5. Monitor recovery process. May refer to V$MANAGED_STANDBY and V$ARCHIVE_DEST_STATUS.

SQL> SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS
  2  FROM V$MANAGED_STANDBY;

PROCESS   STATUS          THREAD#  SEQUENCE#     BLOCK#     BLOCKS
--------- ------------ ---------- ---------- ---------- ----------
ARCH      CONNECTED             0          0          0          0
ARCH      CONNECTED             0          0          0          0
RFS       RECEIVING             1     281940       1161       1161
MRP0      WAIT_FOR_LOG          1     281941          0          0

最后简单看了下alert log,tail之后看到了以下信息:

Completed: ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DI
Sun Jan 18 03:08:43 2009
Media Recovery Log /dtlm02/tlm/o01tlm3arch/stdby_arch/O01TLM3281937.arc
Media Recovery Log /dtlm02/tlm/o01tlm3arch/stdby_arch/O01TLM3281938.arc
Media Recovery Log /dtlm02/tlm/o01tlm3arch/stdby_arch/O01TLM3281939.arc
Media Recovery Log /dtlm02/tlm/o01tlm3arch/stdby_arch/O01TLM3281940.arc
Media Recovery Waiting for thread 1 seq# 281941

随后主观臆断为启动成功,通知requestor继续下一步

整个过程被催了一次,主要是由于10g和9i的命令区别阿~~~兄弟们一定要注意了,先搞清楚版本,然后根据版本搞清楚具体命令,被搞过好多次了,一定要吸取教训:)

Stop过程也类似,一定要注意不同版本间具体命令的区别。关于Dataguard,10g和9i的区别好像有很多,有空要好好总结下。
