Oracle 11g RAC + DG安裝詳解--03

三、創建asm 磁盤組

這一步也可以放到安裝完oracle 軟件后再做。

任一節點，grid 用戶下執行：

[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、安裝oracle 軟件

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

[oracle@rac1 database]$ ls

doc  install  response  rpm  runInstaller  sshsetup  stage  welcome.html

[oracle@rac1 database]$ ./runInstaller

接下來又是漫長的等待，但這一步是安裝過程中唯一不會出問題的。

節點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.

節點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.

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.

五、建庫

[oracle@rac1 database]$ cd

[oracle@rac1 ~]$ dbca

All initilization parameters 里面修改db_files 參數
