Oracle 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/shif [ ！ -d "/var/opt/oracle" ]; thenmkdir -p /var/opt/oracle;fiif [ -d "/var/opt/oracle" ]; thenchmod 755 /var/opt/oracle;fiif [ -f "/oracle/oraInventory/oraInst.loc" ]; thencp /oracle/oraInventory/oraInst.loc /var/opt/oracle/oraInst.loc;chmod 644 /var/opt/oracle/oraInst.loc;elseINVPTR=/var/opt/oracle/oraInst.locINVLOC=/oracle/oraInventoryGRP=oinstallPTRDIR="`dirname $INVPTR`";# Create the software inventory location pointer fileif [ ！ -d "$PTRDIR" ]; then mkdir -p $PTRDIR;fiecho "Creating the Oracle inventory pointer file （$INVPTR）";echo inventory_loc=$INVLOC > $INVPTRecho inst_group=$GRP >> $INVPTRchmod 644 $INVPTR# Create the inventory directory if it doesn"t existif [ ！ -d "$INVLOC" ];then echo "Creating the Oracle inventory directory （$INVLOC）"; mkdir -p $INVLOC;fifiecho "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！";fiecho "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！";fiecho "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 oraInst.locroot@node2 # more oraInst.locinventory_loc=/oracle/oraInventoryinst_group=oinstall 在另一个节点上运行该脚本root@node1 #/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 2.

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|grep crs|grep -v grep oracle 18347 17447 0 14:51:06 ？ 0:00 /oracle/crs/bin/evmlogger.bin -o /oracle/crs/evm/log/evmlogger.info -l /oracle/oracle 17447 1 0 14:50:47 ？ 0:00 /oracle/crs/bin/evmd.binoracle 17763 17756 0 14:50:48 ？ 0:00 /oracle/crs/bin/ocssd.binoracle 17756 17643 0 14:50:48 ？ 0:00 /bin/sh -c ulimit -c unlimited; cd /oracle/crs/log/node1/cssd; /oracle/crsoracle 21216 1 0 14:52:28 ？ 0:00 /oracle/crs/opmn/bin/ons -doracle 21217 21216 0 14:52:28 ？ 0:00 /oracle/crs/opmn/bin/ons -doracle 17771 17642 0 14:50:48 ？ 0:00 /bin/sh -c cd /oracle/crs/log/node1/cssd/oclsmon; ulimit -c unlimited; /oraoracle 17773 17771 0 14:50:48 ？ 0:00 /oracle/crs/bin/oclsmon.binroot 17449 1 0 14:50:47 ？ 0:01 /oracle/crs/bin/crsd.bin reboot root@node2 # ps -ef|grep crs|grep -v greporacle 18212 18211 0 14:47:28 ？ 0:00 /oracle/crs/bin/ocssd.binoracle 27467 27466 0 14:52:25 ？ 0:00 /oracle/crs/opmn/bin/ons -doracle 25252 17886 0 14:51:16 ？ 0:00 /oracle/crs/bin/evmlogger.bin -o /oracle/crs/evm/log/evmlogger.info -l /oracle/oracle 27466 1 0 14:52:25 ？ 0:00 /oracle/crs/opmn/bin/ons -doracle 18191 18180 0 14:47:28 ？ 0:00 /oracle/crs/bin/oclsmon.binoracle 17886 1 0 14:47:27 ？ 0:00 /oracle/crs/bin/evmd.binoracle 18180 18092 0 14:47:28 ？ 0:00 /bin/sh -c cd /oracle/crs/log/node2/cssd/oclsmon; ulimit -c unlimited; /oraroot 17889 1 0 14:47:27 ？ 0:00 /oracle/crs/bin/crsd.bin reboot oracle 18211 18093 0 14:47:28 ？ 0:00 /bin/sh -c ulimit -c unlimited; 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。 root@node1 # crs_stat -tName Type Target State Host ------------------------------------------------------------ora....c03.gsd application ONLINE ONLINE node1 ora....c03.ons application ONLINE ONLINE node1 ora....c03.vip application ONLINE ONLINE node1 ora....c04.gsd application ONLINE ONLINE node2 ora....c04.ons application ONLINE ONLINE node2 ora....c04.vip application ONLINE ONLINE node1 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.shRunning Oracle10 root.sh script...
