Oracle 11g RAC + DG安装详解--03

三、创建asm 磁盘组

这一步也可以放到安装完oracle 软件后再做。

任一节点，grid 用户下执行：

[grid@rac1 ~]$ asmcmd

ASMCMD> mkdg '<dg name="FRA" redundancy="external"> <dsk string="/dev/asmdisk_fra" /> </dg>'

ASMCMD> mkdg '<dg name="SASDATA" redundancy="external"> <dsk string="/dev/asmdisk_sasdata1" /> <dsk string="/dev/asmdisk_sasdata2" /> <dsk string="/dev/asmdisk_sasdata3" /> </dg>'

ASMCMD> mkdg '<dg name="SSDDATA" redundancy="external"> <dsk string="/dev/asmdisk_ssddata1" /> <dsk string="/dev/asmdisk_ssddata2" /> <dsk string="/dev/asmdisk_ssddata3" /> </dg>'

ASMCMD> mkdg '<dg name="ARCH" redundancy="external"> <dsk string="/dev/asmdisk_arch" /> </dg>'

ASMCMD> mkdg '<dg name="SSDDATA" redundancy="external"> <dsk string="/dev/asmdisk_ssddata1" /> <dsk string="/dev/asmdisk_ssddata2" /> <dsk string="/dev/asmdisk_ssddata3" /> </dg>'

ASMCMD> lsdg

四、安装oracle 软件

 [oracle@rac1 ~]$ cd /home/software/database

[oracle@rac1 database]$ ls

doc  install  response  rpm  runInstaller  sshsetup  stage  welcome.html

[oracle@rac1 database]$ ./runInstaller

接下来又是漫长的等待，但这一步是安装过程中唯一不会出问题的。

节点1

[root@TRAC1 lib]# /home/app/oracle/product/11.2.0/root.sh

Performing root user operation for Oracle 11g

The following environment variables are set as:

    ORACLE_OWNER= oracle

    ORACLE_HOME=  /home/app/oracle/product/11.2.0

Enter the full pathname of the local bin directory: [/usr/local/bin]:

The contents of "dbhome" have not changed. No need to overwrite.

The contents of "oraenv" have not changed. No need to overwrite.

The contents of "coraenv" have not changed. No need to overwrite.

Entries will be added to the /etc/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root script.

Now product-specific root actions will be performed.

Finished product-specific root actions.

节点2

[root@TRAC2 lib]# /home/app/oracle/product/11.2.0/root.sh

Performing root user operation for Oracle 11g

The following environment variables are set as:

    ORACLE_OWNER= oracle

    ORACLE_HOME=  /home/app/oracle/product/11.2.0

Enter the full pathname of the local bin directory: [/usr/local/bin]:

The contents of "dbhome" have not changed. No need to overwrite.

The contents of "oraenv" have not changed. No need to overwrite.

Database Configuration Assistant when a database is created

Finished running generic part of root script.

Now product-specific root actions will be performed.

Finished product-specific root actions.

五、建库

[oracle@rac1 database]$ cd

[oracle@rac1 ~]$ dbca

All initilization parameters 里面修改db_files 参数
