好长时间没有来更新博客了，在没有完全完成一项工作时也不知道如何去将中间出现的问题整理出来，因为太多了，还有时间缘故，来不及整理，想赶紧做完。花了有一两个月了吧，终于在今天早上成功安装好rac，材料正在整理中。。。

问题1：安装好后想赶紧来个切换服务的测试：

            关掉第一个节点后：

SQL> select instance_number instance#,instance_name,host_name,status from v$instance;

 INSTANCE# INSTANCE_NAME    HOST_NAME  STATUS

---------- ---------------- ---------- ------------

         2 devdb2           rac2       OPEN

SQL> select failover_type,failover_method,failed_over from v$session where username='SYSTEM';

FAILOVER_TYPE FAILOVER_M FAI

------------- ---------- ---

SELECT        BASIC      YES

节点二启动了服务，恢复 devdb1 之后，CRM 服务不会自动重新定位到首选实例。您必须手动将服务重新定位到 devdb1

SQL> startup

ORACLE instance started.

SQL> show parameter service

NAME                           TYPE        VALUE

------------------------------ ----------- ------------------------

service_names                  string      devdb

从这里看出，CRM没有在devdb1上

SQL> conn system/oracle@devdb2

Connected.

SQL> show parameter service

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

service_names                        string      devdb, CRM

从这里看到，目前CRM挂接在devdb2上

另外打开一个窗口，以oracle用户执行下面语句，切换服务CRM到devdb1上

rac1-> srvctl relocate service -d devdb -s crm -i devdb2 -t devdb1

/u01/oracle/product/10.2.0/db_1/jdk/jre/bin/java: error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory

注释掉vi /u01/oracle/product/10.2.0/db_1/bin/srvctl的 LD_ASSUME_KERNEL

[oracle@rac1 bin]$ srvctl relocate service -d devdb -s crm -i devdb2 -t devdb1

[oracle@rac1 bin]$

[oracle@rac1 admin]$ sqlplus / as sysdba
