RAC安装时需要执行4个脚本及意义

RAC安装时需要执行4个脚本

1)$ORACLE_BASE/oraInventory/orainstRoot.sh(clusterware结束时执行)

2)$CRS_HOME/root.sh(clusterware结束时执行)

3)$CRS_HOME/bin/vipca.sh(该脚本是在第二个节点执行$CRS_HOME/root.sh时被自动调用)

4)$ORACLE_HOME/root.sh(安装完数据库以后执行)

1.orainstRoot.sh脚本

if[$?!=0];then

echo"OUI-10057:WARNING:chgrpof/oracle/oraInventorytooinstallfailed!";

fi

echo"Theexecutionofthescriptiscomplete"

从脚本我们可以看出，这个脚本主要是创建/var/opt/oracle目录（如果不存在的话）,再在该目录下建oraInst.loc文件（该文件记录orainventory的位置和组）。并改变orainventory的属性。

从输出我们可以看出，该脚本主要执行crs的配置，格式化ocrdisk,更新/etc/inittab文件，启动css进程，在/var/opt/oracle/新建了ocr.loc文件及，scls_scr，oprocd文件夹。

2.2查看crs进程及/etc/inittab文件可以看出节点的变化。

注意：新创建了ocr.loc，scls_scr，oprocd，但没有创建/var/opt/oracle/oratab。

-rw-r--r--1rootroot1240Apr214:50inittab.crs

该脚本会将inittab复制为inittab.no_crs,修改后的inittab另复制一份为inittab.crs.

2.3在另外一个节点执行$CRS_HOME/root.sh

3.在第二个节点上运行时会多比在第一个节点上运行多执行一个任务

-------运行$CRS_HOME/bin/vipca.sh

VIPCA.sh主要是配置vip并启动crs的默认资源（未建库时默认为6个）,多启动三个后台进程。

root@node1#ps-ef|grepcrs|grep-vgrep

oracle1821118093014:47:28?0:00/bin/sh-culimit-cunlimited;cd/oracle/crs/log/node2/cssd;/oracle/crs

从现在node2上的进程就能看出，执行完vipca.sh后，会多出三个后台进程。

4.安装数据库软件（binary）时需在最后一步：执行$ORACLE_HOME/root.sh

root@node2#$ORACLE_HOME/root.sh

该脚本的作用在于在指定的目录(默认为/usr/local/bin)下创建dbhome,oraenv,coraenv,在/var/opt/oracle/里创建oratab文件。
