准备工作

在安装Oracle 12补丁之前，需要做好以下准备工作：

1、确保操作系统已经安装了所需的补丁和更新，建议使用最小化安装的操作系统，并根据实际情况安装所需的组件和服务。

2、关闭所有与Oracle相关的服务，可以使用以下命令关闭Oracle服务：

“`

$ lsnrctl stop

$ ora_pmon_stop

$ ora_cman_stop

$ ora_smon_stop

$ ora_mmon_stop

$ ora_trc_stop

$ ora_qmgr_stop

$ ora_emdg_stop

$ ora_nfs_stop

$ ora_dpdump_stop

$ ora_ksrmgr_stop

$ ora_net1_stop

$ ora_net8_stop

$ ora_listener_stop

“`

3、确保Oracle主目录和临时目录具有正确的权限，可以使用以下命令设置权限：

“`

chown R oracle:dba /u01/app/oracle/product/12.1.0/dbhome_1

chown R oracle:dba /u01/app/oracle/oradata/orcl

chmod R 775 /u01/app/oracle/product/12.1.0/dbhome_1

chmod R 775 /u01/app/oracle/oradata/orcl

“`

4、确保Oracle主目录下的scripts目录存在，并具有可执行权限，可以使用以下命令创建scripts目录并设置权限：

“`

mkdir p /u01/app/oracle/product/12.1.0/dbhome_1/scripts

chmod +x /u01/app/oracle/product/12.1.0/dbhome_1/scripts/*.sh

“`

安装Oracle 12补丁

1、从Oracle官方网站下载Oracle 12补丁包，注意选择与您的Oracle版本和操作系统相匹配的补丁包，下载完成后，将补丁包上传到Linux服务器上。

2、解压补丁包，可以使用以下命令解压补丁包：

“`

unzip patch_package.zip d /u01/app/oracle/product/12.1.0/dbhome_1/scripts

“`

3、以Oracle管理员身份登录到Linux服务器，可以使用以下命令切换到Oracle用户：

“`

sudo su oracle

“`

4、运行补丁安装脚本，可以使用以下命令运行补丁安装脚本：

“`

cd /u01/app/oracle/product/12.1.0/dbhome_1/scripts

./runInstaller silent force ignorePrereq waitforcompletion responseFile /tmp/responsefile.rsp ignoreSysPrereqs ignoreOsPrereqs ignoreDbPrereqs ignoreConfigParams ignoreDependencies ignoreVersionCheck novalidation ignorePerfReqs ignorePlatform os=LINUX64,release=6.8,edition=EE waitforfile /u01/app/oraInventory/oraInventory.xml install destination /u01/app/oracle sysprep /u01/app/oraInventory copydb action="install" version "12.1.0.2.0" glance="/u01/app/oracle/product/12.1.0/dbhome_1" characterSet AL32UTF8 NONE skipPrereqCheck true ignorePrereq false ignoreSysPrereq false ignoreOsPrereq false ignoreDbPrereq false ignoreConfigParams false ignoreDependencies false ignoreVersionCheck false novalidation false ignorePerfReqs false ignorePlatform false waitforfile true waitforcompletion true responseFile "/tmp/responsefile.rsp" silentMode false force false waitforfile "/u01/app/oraInventory/oraInventory.xml" install true destination "/u01/app/oracle" sysprep "/u01/app/oraInventory" copydb true action "install" version "12.1.0.2.0" glance "/u01/app/oracle/product/12.1.0/dbhome_1" characterSet "AL32UTF8" NONE true skipPrereqCheck true ignorePrereq true ignoreSysPrereq true ignoreOsPrereq true ignoreDbPrereq true ignoreConfigParams true ignoreDependencies true ignoreVersionCheck true novalidation true ignorePerfReqs true ignorePlatform true waitforfile true waitforcompletion true responseFile "/tmp/responsefile.rsp" silentMode true force true

5、等待补丁安装完成，安装过程可能需要一段时间，请耐心等待，安装完成后，会显示类似以下的提示信息：
