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.
