執行orainstRoot.sh 與 root.sh 的作用

[root@gnd-dataguard oraInventory]# sh orainstRoot.sh
Changing permissions of /u01/product/oraInventory to 770.
Changing groupname of /u01/product/oraInventory to dba.
The execution of the script. is complete

修改 /u01/product/oraInventory 目錄許可權。

 

---------------------------------------------------------------------------------  

root.sh 動作可以參考以下：

[root@gnd-dataguard oracle]# sh root.sh
Running Oracle10 root.sh script...

The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u01/product/oracle

Enter the full pathname of the local bin directory: [/usr/local/bin]:
Copying dbhome to /usr/local/bin ...
Copying oraenv to /usr/local/bin ...
Copying coraenv to /usr/local/bin ...

Creating /etc/oratab file...
Entries will be added to the /etc/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.

可以看到：

gnd-dataguard$ls
coraenv dbhome oraenv

EPDIDB$cat oratab
#

# This file is used by ORACLE utilities. It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.

# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form.:
# $ORACLE_SID:$ORACLE_HOME::
#
# The first and second fields are the system identifier and home
# directory of the database respectively. The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.
#
#
# *:/u01/product/oracle:N
*:/u01/product/oracle:N
epd1:/u01/product/oracle:N
EPDIDB$

 

其中  epd1:/u01/product/oracle:N   ， N 表示SID為epd1的資料庫不隨OS系統啟動而啟動 。 修改為Y 後在OS啟動的時候資料庫會自動啟動 。

 

例子：

 

epd2db$cat oratab
#

# This file is used by ORACLE utilities.  It is created by root.sh
# and updated by the Database Configuration Assistant when creating

epd2:/u01/product/oracle:Y
ibml6rma:/u01/product/oracle:Y

還有Oracle軟體安裝時候的幾個檔案，如下

epd2db$ls
coraenv  dbhome  oraenv

有興趣可以去看看他們是做什麼用的 。
