RedHat EL5 安装Oracle 10g RAC之--建库
系统环境：
操作系统：RedHat EL5
Cluster： Oracle CRS 10.2.0.1.0
Oracle： Oracle 10.2.0.1.0
如图所示：RAC 系统架构
四、通过DBCA建立数据库
1、首先通过DBCA配置ASM磁盘组
[oracle@node1 install]$dbca
选择RAC环境建库
选择ASM磁盘组管理
创建ASM Instance ，注意选择用pfile ，易于管理
创建ASM Instance
提示：创建ASM Instance将创建listener
创建ASM DISKGROUP，dg1用于存储database，采用normal冗余，选择两个raw
创建ASM DISKGROUP，rcy1用于存储Recovery Area，采用normal冗余，选择两个raw
2、磁盘组创建完成后，开始建库
开始建库
注意选择所有node
配置库名
存储介质，选择ASM
DataBase存放在dg1 diskgroup
Recovery Area 存放在rcy1 diskgroup
建库开始
建库完成！
五、验证RAC
[root@node1 ~]# crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
[root@node1 ~]# crs_stat -t
Name Type Target State Host
------------------------------------------------------------
ora....SM1.asm application ONLINE ONLINE node1
ora....E1.lsnr application ONLINE ONLINE node1
ora.node1.gsd application ONLINE ONLINE node1
ora.node1.ons application ONLINE ONLINE node1
ora.node1.vip application ONLINE ONLINE node1
ora....SM2.asm application ONLINE ONLINE node2
ora....E2.lsnr application ONLINE ONLINE node2
ora.node2.gsd application ONLINE ONLINE node2
ora.node2.ons application ONLINE ONLINE node2
ora.node2.vip application ONLINE ONLINE node2
ora.prod.db application ONLINE ONLINE node1
ora....d1.inst application ONLINE ONLINE node1
ora....d2.inst application ONLINE ONLINE node2
[root@node1 ~]#
[root@node2 ~]# crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
[root@node2 ~]# crs_stat -t
Name Type Target State Host
------------------------------------------------------------
ora....SM1.asm application ONLINE ONLINE node1
ora....E1.lsnr application ONLINE ONLINE node1
ora.node1.gsd application ONLINE ONLINE node1
ora.node1.ons application ONLINE ONLINE node1
ora.node1.vip application ONLINE ONLINE node1
ora....SM2.asm application ONLINE ONLINE node2
ora....E2.lsnr application ONLINE ONLINE node2
ora.node2.gsd application ONLINE ONLINE node2
ora.node2.ons application ONLINE ONLINE node2
ora.node2.vip application ONLINE ONLINE node2
ora.prod.db application ONLINE ONLINE node1
ora....d1.inst application ONLINE ONLINE node1
ora....d2.inst application ONLINE ONLINE node2
SQL> select instance_name,status from gv$instance;
INSTANCE_NAME STATUS
---------------- ------------
prod2 OPEN
prod1 OPEN
附：错误案例
安装完成后Oracle用户执行srvctl出现以下错误：
[oracle@node2 ~]$ srvctl stop database -d prod
/u01/app/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
[oracle@node2 ~]$ cd $ORACLE_HOME/bin（注意是Oracle软件主目录）
[oracle@node2 bin]$ vi srvctl
#Remove this workaround when the bug 3937317 is fixed
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
unset LD_ASSUME_KERNEL （在文件中添加此行信息）
--问题解决！
@至此在RedHat EL5下安装Oracle 10g RAC的工作告一段落，对RAC的管理和维护还任重而道远！
