在OEL6.8上安装12.2 RAC

Oracle Cluster Domain

Oracle Cluster Domain是Oracle Clusterware 12c Release 2中的一个新功能,包含了下面的组件


Oracle Domain Services Cluster
Oracle Member Cluster for Oracle Database
Oracle Member Cluster for Applications.



Oracle Cluster Domain enables you to standardize, centralize, and optimize your Oracle Real Application Clusters (Oracle RAC) deployment for the private database cloud. Multiple cluster configurations are grouped under an Oracle Cluster Domain for management purposes and make use of shared services available within that Oracle Cluster Domain. The cluster configurations within that Oracle Cluster Domain include Oracle Domain Services Cluster and Oracle Member Clusters.

The Oracle Domain Services Cluster provides centralized services to other clusters within the Oracle Cluster Domain. These services include:

    A centralized Grid Infrastructure Management Repository (housing the MGMTDB for each of the clusters within the Oracle Cluster Domain)

    Trace File Analyzer (TFA) services, for targeted diagnostic data collection for Oracle Clusterware and Oracle Database

    Consolidated Oracle ASM storage management service

    An optional Rapid Home Provisioning (RHP) Service to install clusters, and provision, patch, and upgrade Oracle Grid Infrastructure and Oracle Database homes. When you configure the Oracle Domain Services Cluster, you can also choose to configure the Rapid Home Provisioning Server.


和之前安装方式的不同

12.2之前,我们通过runInstaller命令去安装集群软件,安装文件包含很多的jar文件,安装的时候需要再次解压。在12.2中,集群软件是已经打包好的,只需要解压,然后共同gridSetup.sh脚本去安装就好。其中gridSetup.sh所在的目录就是GI_HOME的目录。

[orgrid@ohs1 122]$ cd $ORACLE_HOME
[orgrid@ohs1 122]$ pwd
/pgold/orgrid/oracle/product/122
[orgrid@ohs1 122]$ ls -l gridSetup.sh 
-rwxr-x---. 1 orgrid oinstall 5395 Jul 21  2016 gridSetup.sh
[orgrid@ohs1 122]$ ./gridSetup.sh

安装多样性
支持不同类型的安装方式,包括Extended Cluster

注意:支持NFS,之前的版本,没有明确标识

OCR和MGMT数据库可以放在同一个磁盘组或者不同的磁盘组

注意:选择YES,将放在不同的磁盘组,选择No将放在同一磁盘组

支持Configure Oracle ASM Filter Driver

注意:支持ASMFD,但不支持和ASMLIB一起使用,本次实验使用了ASMLIB,故不支持

指定GRID_BASE,无需指定GRID_HOME

注意:由于软件解压后的目录就是GRID_HOME,所以安装时不会让你再次指定
