2.下载补丁包和opatch的升级包

要具有开源精神
opatch升级包：
https://dxz.jb51.net/202308/yuanma/OPatch_jb51.rar
19.18的补丁包
链接: https://pan.baidu.com/s/10GbaiIoXqQHDqd7Q2p1clg

提取码: bqdh

3.检查OPatch的版本

更新opatch，根据README要求，opatch工具版本至少12.2.0.1.34 或更高版本

[oracle@localhost ~]$ cd $ORACLE_HOME
[oracle@localhost db_1]$ cd OPatch/
[oracle@localhost OPatch]$ ./opatch version
OPatch Version: 12.2.0.1.17
OPatch succeeded.

升级opatch版本

#备份OPatch
[oracle@localhost ~]$ mv $ORACLE_HOME/OPatch  $ORACLE_HOME/OPatch.bak
#解压到$ORACLE_HOME目录下
[oracle@localhost ~]$ unzip p6880880_190000_Linux-x86-64.zip  -d $ORACLE_HOME
#查看升级后的opatch的版本
[oracle@localhost ~]$ cd $ORACLE_HOME
[oracle@localhost db_1]$ cd OPatch/
[oracle@localhost OPatch]$ ./opatch version
OPatch Version: 12.2.0.1.36
OPatch succeeded.

4.检查补丁是否冲突

[oracle@localhost ~]$ unzip p34762026_190000_Linux-x86-64.zip
[oracle@localhost ~]$ chown -R  oracle:oinstall   34762026/
[oracle@localhost ~]$ chmod 775 -R 34762026/
#检测冲突,依次检测
[oracle@localhost ~]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph /home/oracle/34762026/33575402/
[oracle@localhost ~]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph /home/oracle/34762026/34765931/
[oracle@localhost ~]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph /home/oracle/34762026/34768559/
[oracle@localhost ~]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph /home/oracle/34762026/34768569/
[oracle@localhost ~]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph /home/oracle/34762026/34863894/

5.关闭数据库实例，关闭监听

[oracle@localhost ~]$ sqlplus / as sysdba
SQL*Plus: Release 19.0.0.0.0 - Production on Tue Aug 8 06:53:08 2023
Version 19.3.0.0.0

Version 19.3.0.0.0
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> exit
Disconnected from Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production
Version 19.3.0.0.0
[oracle@localhost ~]$ lsnrctl stop
LSNRCTL for Linux: Version 19.0.0.0.0 - Production on 08-AUG-2023 07:13:07

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))
The command completed successfully

6.应用patch

[oracle@localhost 34765931]$ pwd
/home/oracle/34762026/34765931
[oracle@localhost 34765931]$ $ORACLE_HOME/OPatch/opatch apply
Oracle Interim Patch Installer version 12.2.0.1.36

7.加载变化的SQL到数据库

安装补丁之后，还需要将有变化的SQL加载到数据库中，这里可以直接运行Datapatch工具将这些修改的SQL重新加载到数据库中，如果是RAC环境，只需要在一个节点执行就可以了。

根据readme的说明，操作步骤如下：

sqlplus /nolog
SQL> Connect / as sysdba
SQL> startup
SQL> alter pluggable database all open;
SQL> quit
cd $ORACLE_HOME/OPatch
./datapatch -verbose

在这里插入图片描述

8.ORACLE升级补丁查询

1.查询dba_server_registry视图

SQL> select comp_name,version from dba_server_registry;

2.查询dba_registry_history

SQL> select * from dba_registry_history;

3.查询product_component_version视图

SQL> select product,version from product_component_version;

4.查询v$version视图

SQL> select * from v$version;
