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/oralnventory/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. orainstRootsh 脚本 1.1 orainstRootsh脚本执行过程 rootnode2 /oracle/oraInventory/orainstRoot.sh Changing permissions of /oracle/oralnventory to 770. Changing groupname of /oracle/oralnventory to oinstall. The cution of the script is complete 1.2 orainstRootsh 脚本内容 rootnodel more /oracle/oralnventory/orainstRootsh /bin/sh if [ -d /var/opt/oracle ]; then mkdir -p /var/opt/oracle; fi if [ -d /var/opt/oracle ]; then chmod 755 /var/opt/oracle; fi if [ -f/oracle/oralnventory/oralnstloc ]; then cp /oracle/oralnventory/oralnstloc /var/opt/oracle/oralnst.loc; chmod 644 /var/opt/oracle/oralnst.loc; else INVPTR/var/opt/oracle/oraInst.loc INVLOC/oracle / oralnventory GRPoinstall PTRDIR二”dirname INVPTR“； Create the software inventory location pointer file if [ -d SPTRDIR]; then mkdir -p PTRDIR; fi echo Creating the Oracle inventory pointer file INVPTR; echo inventory_locINVLOC INVPTR echo inst_groupGRP INVPTR chmod 644 INVPTR Create the inventory directory if it doesnt exist if [ -d HINVLOC];then echo Creating the Oracle inventory directory [INVLOC]; mkdir -p INVLOC; fi fi echo Changing permissions of /oracle/oralnventory to 770.; chmod -R 770 /oracle/oralnventory; if [ 0 ]; then echo OUI-35086WARNING chmod of /oracle/oralnventory to 770 failed; fi echo Changing groupname of /oracle/oralnventory to oinstall.; chgrp oinstall /oracle/oralnventory; if [ 0 ]; then echo OUI-10057WARNING chgrp of /oracle/oralnventory to oinstall failed; fi echo The cution of the script is complete 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oralnst.loc文件（该文件记录orainventory的位置和组）。 并改变orainventory的属性。 rootnode2 Is -rlt /var/opt/oracle/ total 2 -rw-r-r- 1 root root 55 Apr 2 1442 oralnst.loc rootnode2 more oralnst.loc inventory_loc/oracle / orainventory inst_groupoinstall 在另一个节点上运行该脚本 rootnodel /oracle/oraInventory/orainstRoot.sh Changing permissions of /oracle/orainventory to 770.
