--关闭EM

emctl status dbconsole
emctl stop dbconsole

--关闭数据库和监听

srvctl stop database -d ptfdb
srvctl stop listener -n ptfdb1
srvctl stop listener -n ptfdb2

1、查看数据库安装的补丁

$ORACLE_HOME/OPatch/opatch lsinventory

2、解压 patch 包

unzip p20760997_112030_Linux-x86-64.zip
cd 20760997/

3、检查是否满足补丁安装条件

$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph ./

4、安装补丁

cd 20760997
$ORACLE_HOME/OPatch/opatch apply

在安装补丁的过程中，安装完本地补丁后，会提示是否安装远程节点的补丁，选择是即可。

5、安装补丁后的操作

--启动数据库和监听

srvctl start database -d ptfdb

srvctl start listener -n ptfdb1
srvctl start listener -n ptfdb2

cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
CONNECT / AS SYSDBA
STARTUP
@catbundle.sql psu apply
QUIT

cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> @utlrp.sql

--检查安装的补丁

select * from dba_registry_history;
SELECT comp_name, version, status FROM dba_registry;

6、安装中的报错

Invoking prereq "checkconflictagainstohwithdetail"
OracleHomeInventory was not able to create a lock file, probably due to a failed OPatch Session. The loaded inventory might not show correctly what you have in the Oracle Home.

--解决方法

这是由于JAVA池分配的太小了，更改JAVA池后，重启数据库。
alter system set java_pool_size=300M scope=spfile;

--报错二

OUI-67076:OracleHomeInventory was not able to create a lock file, probably due to a failed OPatch Session. The loaded inventory might not show correctly what you have in the Oracle Home.

--解决方法

cd $ORACLE_HOME/.patch_storage
mv patch_locked patch_locked.back
