RAC安裝時需要執行4個指令碼

1) $ORACLE_BASE/oraInventory/orainstRoot.sh (clusterware 結束時執行)

2) $CRS_HOME/root.sh (clusterware 結束時執行)

3) $CRS_HOME/bin/vipca.sh(該指令碼是在第二個節點執行$CRS_HOME/root.sh時被自動呼叫)

4) $ORACLE_HOME/root.sh (安裝完資料庫以後執行)

1. orainstRoot.sh 指令碼

1.1 orainstRoot.sh 指令碼執行過程

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 指令碼內容

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

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"

從指令碼我們可以看出，這個指令碼主要是建立/var/opt/oracle目錄（如果不存在的話）,再在該目錄下建oraInst.loc檔案（該檔案記錄orainventory的位置和組）。並改變orainventory的屬性。

root@node2 # ls –rlt /var/opt/oracle/

total 2

-rw-r--r-- 1 root root 55 Apr 2 14:42 oraInst.loc

root@node2 # more oraInst.loc

inventory_loc=/oracle/oraInventory

inst_group=oinstall

在另一個節點上執行該指令碼

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. Root.sh 指令碼

2.1 root.sh 指令碼執行過程

#/oracle/crs/root.sh

WARNING: directory '/oracle' is not owned by root

Checking to see if Oracle CRS stack is already configured

Checking to see if any 9i GSD is up

node2

從輸出我們可以看出，該指令碼主要執行crs的配置，格式化ocr disk,更新/etc/inittab檔案，啟動css程式，在/var/opt/oracle/新建了ocr.loc檔案及，scls_scr，oprocd資料夾。

2.2 檢視crs程式及/etc/inittab檔案可以看出節點的變化。

root@node2 # ps -ef|grep crs|grep –v grep

oracle 18212 18211 0 14:47:28 ? 0:00 /oracle/crs/bin/ocssd.bin

root 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

root@node2 # ls –rlt /var/opt/oracle/

total 8

-rw-r--r-- 1 root root 55 Apr 2 14:42 oraInst.loc

drwxrwxr-x 5 root root 512 Apr 2 14:47 oprocd

drwxr-xr-x 3 root root 512 Apr 2 14:47 scls_scr

-rw-r--r-- 1 root oinstall 48 Apr 2 14:47 ocr.loc

注意：新建立了ocr.loc，scls_scr，oprocd，但沒有建立/var/opt/oracle/oratab。

root@node1 # more inittab

# Use is subject to license terms.

#

# The /etc/inittab file controls the configuration of init(1M); for more

# information refer to init(1M) and inittab(4). It is no longer

# necessary to edit inittab(4) directly; administrators should use the

# Solaris Service Management Facility (SMF) to define services instead.

# Refer to smf(5) and the System Administration Guide for more

# information on SMF.

#

# For modifying parameters passed to ttymon, use svccfg(1m) to modify

# the SMF repository. For example:

#

# # svccfg

# svc:> select system/console-login

# svc:/system/console-login> setprop ttymon/terminal_type = "xterm"

# svc:/system/console-login> exit

#

#ident "@(#)inittab 1.41 04/12/14 SMI"

ap::sysinit:/sbin/autopush -f /etc/iu.ap

sp::sysinit:/sbin/soconfig -f /etc/sock2path

smf::sysinit:/lib/svc/bin/svc.startd >/dev/msglog 2<>/dev/msglog

root@node1 # ls -rlt /etc/inittab*

-rw-r--r-- 1 root root 1072 Nov 2 12:39 inittab.cssd

-rw-r--r-- 1 root root 1206 Mar 21 17:15 inittab.pre10203

-rw-r--r-- 1 root root 1006 Mar 21 17:15 inittab.nocrs10203

-rw-r--r-- 1 root root 1040 Apr 2 14:50 inittab.orig

-rw-r--r-- 1 root root 1040 Apr 2 14:50 inittab.no_crs

-rw-r--r-- 1 root root 1240 Apr 2 14:50 inittab

-rw-r--r-- 1 root root 1240 Apr 2 14:50 inittab.crs

該指令碼會將inittab複製為inittab.no_crs,修改後的inittab另複製一份為inittab.crs.

2.3 在另外一個節點執行$CRS_HOME/root.sh

root@node1 #/oracle/crs/root.sh

WARNING: directory '/oracle' is not owned by root

Checking to see if Oracle CRS stack is already configured

Checking to see if any 9i GSD is up

3. 在第二個節點上執行時會多比在第一個節點上執行多執行一個任務

-------執行$CRS_HOME/bin/vipca.sh

VIPCA.sh主要是配置vip並啟動crs的預設資源（未建庫時預設為6個）,多啟動三個後臺程式。

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.bin

oracle 17763 17756 0 14:50:48 ? 0:00 /oracle/crs/bin/ocssd.bin

oracle 17756 17643 0 14:50:48 ? 0:00 /bin/sh -c ulimit -c unlimited; cd /oracle/crs/log/node1/cssd; /oracle/crs

oracle 21216 1 0 14:52:28 ? 0:00 /oracle/crs/opmn/bin/ons -d

oracle 21217 21216 0 14:52:28 ? 0:00 /oracle/crs/opmn/bin/ons -d

oracle 17771 17642 0 14:50:48 ? 0:00 /bin/sh -c cd /oracle/crs/log/node1/cssd/oclsmon; ulimit -c unlimited; /ora

oracle 17773 17771 0 14:50:48 ? 0:00 /oracle/crs/bin/oclsmon.bin

root 17449 1 0 14:50:47 ? 0:01 /oracle/crs/bin/crsd.bin reboot

root@node2 # ps -ef|grep crs|grep -v grep

oracle 18212 18211 0 14:47:28 ? 0:00 /oracle/crs/bin/ocssd.bin

oracle 27467 27466 0 14:52:25 ? 0:00 /oracle/crs/opmn/bin/ons -d

oracle 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 -d

oracle 18191 18180 0 14:47:28 ? 0:00 /oracle/crs/bin/oclsmon.bin

oracle 17886 1 0 14:47:27 ? 0:00 /oracle/crs/bin/evmd.bin

oracle 18180 18092 0 14:47:28 ? 0:00 /bin/sh -c cd /oracle/crs/log/node2/cssd/oclsmon; ulimit -c unlimited; /ora

root 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

從現在node2上的程式就能看出，執行完vipca.sh後，會多出三個後臺程式。

root@node1 # crs_stat -t

Name 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. 安裝資料庫軟體（binary）時需在最後一步：執行$ORACLE_HOME/root.sh

root@node2 #$ORACLE_HOME/root.sh

Running Oracle10 root.sh script...

The following environment variables are set as:

ORACLE_OWNER= oracle

ORACLE_HOME= /oracle/10g

Enter the full pathname of the local bin directory: [/usr/local/bin]:

The file "dbhome" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: y

Copying dbhome to /usr/local/bin ...

The file "oraenv" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: y

Copying oraenv to /usr/local/bin ...

The file "coraenv" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: y

Entries will be added to the /var/opt/oracle/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root.sh script.

Now product-specific root actions will be performed.

該指令碼的作用在於在指定的目錄(預設為/usr/local/bin)下建立dbhome,oraenv,coraenv,在/var/opt/oracle/裡建立oratab檔案。

root@node2# ls –rlt /usr/local/bin

total 18

-rwxr-xr-x 1 oracle root 2428 Apr 2 15:07 dbhome

-rwxr-xr-x 1 oracle root 2560 Apr 2 15:07 oraenv

-rwxr-xr-x 1 oracle root 2857 Apr 2 15:07 coraenv

root@node2 # ls –rlt /var/opt/oracle/

total 10

-rw-r--r-- 1 root root 55 Apr 2 14:42 oraInst.loc

drwxrwxr-x 5 root root 512 Apr 2 14:47 oprocd

drwxr-xr-x 3 root root 512 Apr 2 14:47 scls_scr

-rw-r--r-- 1 root oinstall 48 Apr 2 14:47 ocr.loc

-rw-rw-r-- 1 oracle root 678 Apr 2 15:07 oratab

root@node1 # /oracle/10g/root.sh

Running Oracle10 root.sh script...

The following environment variables are set as:

ORACLE_OWNER= oracle

ORACLE_HOME= /oracle/10g

Enter the full pathname of the local bin directory: [/usr/local/bin]:

The file "dbhome" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: y

Copying dbhome to /usr/local/bin ...

The file "oraenv" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: y

Copying oraenv to /usr/local/bin ...

The file "coraenv" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: y

Copying coraenv to /usr/local/bin ...

Creating /var/opt/oracle/oratab file...

Entries will be added to the /var/opt/oracle/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root.sh script.

Now product-specific root actions will be performed.
