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
1.1 orainstRoot.sh 脚本执行过程
root@node2 #/oracle/oraInventory/orainstRoot.sh
Changing permissions of /oracle/oraInventory to 770.
Changing groupname of /oracle/oraInventory to oinstall.
The execution of the script is complete
1.2 orainstRoot.sh 脚本内容
root@node1 # more /oracle/oraInventory/orainstRoot.sh
#!/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/oraInventory/oraInst.loc" ]; then
cp /oracle/oraInventory/oraInst.loc /var/opt/oracle/oraInst.loc;
chmod 644 /var/opt/oracle/oraInst.loc;
else
INVPTR=/var/opt/oracle/oraInst.loc
INVLOC=/oracle/oraInventory
GRP=oinstall
PTRDIR="`dirname $INVPTR`";
# Create the software inventory location pointer file
if [ ! -d "$PTRDIR" ]; then
mkdir -p $PTRDIR;
fi
echo "Creating the Oracle inventory pointer file ($INVPTR)";
echo inventory_loc=$INVLOC > $INVPTR
echo inst_group=$GRP >> $INVPTR
chmod 644 $INVPTR
# Create the inventory directory if it doesn't exist
if [ ! -d "$INVLOC" ];then
echo "Creating the Oracle inventory directory ($INVLOC)";
mkdir -p $INVLOC;
fi
fi
echo "Changing permissions of /oracle/oraInventory to 770.";
chmod -R 770 /oracle/oraInventory;
if [ $? != 0 ]; then
echo "OUI-35086:WARNING: chmod of /oracle/oraInventory to 770 failed!";
fi
echo "Changing groupname of /oracle/oraInventory to oinstall.";
chgrp oinstall /oracle/oraInventory;
if [ $? != 0 ]; then
echo "OUI-10057:WARNING: chgrp of /oracle/oraInventory to oinstall failed!";
fi
echo "The execution 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oraInst.loc文件(该文件记录orainventory的位置和组)。并改变orainventory的属性。
root@node2 # ls –rlt /var/opt/oracle/
total 2
-rw-r--r-- 1 root root 55 Apr 2 14:42&n
