示例Oracle 10.2.0.1.0升级到10.2.0.4.0一例

1.查看当前系统版本

[oracle@std Disk1]$ sqlplus '/as sysdba'

可以通过以下命令查看数据库位数

[oracle@std Disk1]$ file $ORACLE_HOME/bin/oracle

2.升级前请仔细阅读升级文档

在此我们把升级包p6810189_10204_Linux-x86.zip上传到数据库服务器 并执行 unzip p6810189_10204_Linux-x86.zip

注意：升级之前备份数据

3.停掉ORACLE所有服务

[oracle@std Disk1]$ sqlplus '/as sysdba'

SQL*Plus: Release 10.2.0.1. - Production on Thu Jan  ::

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1. - Production
With the Partitioning, Oracle Label Security, OLAP and Data Mining options

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

[oracle@std Disk1]$ lsnrctl stop
[oracle@std Disk1]$ isqlplusctl stop
[oracle@std Disk1]$ emctl stop dbconsole

4.执行升级程序包

[oracle@std Disk1]$ ./runInstaller
Starting Oracle Universal Installer...

调出图形界面升级界面：

以root身份执行脚本：

[root@std ~]# /u02/app/product/10.2./db_1/root.sh
Running Oracle10 root.sh script...

The following environment variables are set as:
    ORACLE_OWNER= oracle
    ORACLE_HOME=  /u02/app/product/10.2./db_1

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)

   Copying oraenv to /usr/local/bin ...
The file "coraenv" already exists in /usr/local/bin.  Overwrite it? (y/n)

5.执行升级后续脚本

[oracle@std Disk1]$ sqlplus '/as sysdba'
