1.当前DB环境
[oracle@localhost ~]$ cat /etc/redhat-release CentOS Linux release 7.9.2009 (Core) [oracle@localhost ~]$ uname -r 3.10.0-1160.el7.x86_64 [oracle@localhost ~]$ lsnrctl status LSNRCTL for Linux: Version 19.0.0.0.0 - Production on 08-AUG-2023 05:39:02 Copyright (c) 1991, 2019, Oracle.

The command completed successfully [oracle@localhost ~]$ sqlplus / as sysdba SQL*Plus: Release 19.0.0.0.0 - Production on Tue Aug 8 05:40:12 2023 Version 19.3.0.0.0 Copyright (c) 1982, 2019, Oracle. All rights reserved. Connected to: Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production Version 19.3.0.0.0
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

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 ~]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph /home/oracle/34762026/33575402/ [oracle@localhost ~]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph /home/oracle/34762026/34765931/ [oracle@localhost ~]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph /home/oracle/34762026/34768559/ [oracle@localhost ~]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph /home/oracle/34762026/34768569/ [oracle@localhost ~]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph /home/oracle/34762026/34863894/ #出现以下字样，检测成功 Oracle Interim Patch Installer version 12.2.0.1.36 Copyright (c) 2023, Oracle Corporation. All rights reserved. PREREQ session Oracle Home : /u01/app/oracle/product/19c/db_1 Central Inventory : /u01/oraInventory from : /u01/app/oracle/product/19c/db_1/oraInst.loc OPatch version : 12.2.0.1.36 OUI version : 12.2.0.7.0 Log file location : /u01/app/oracle/product/19c/db_1/cfgtoollogs/opatch/opatch2023-08-08_06-47-50AM_1.log Invoking prereq "checkconflictagainstohwithdetail" Prereq "checkConflictAgainstOHWithDetail" passed. OPatch succeeded.
5.关闭数据库实例，关闭监听
[oracle@localhost ~]$ 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 Copyright (c) 1982, 2019, Oracle. All rights reserved. Connected to: Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production 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 Copyright (c) 1991, 2019, Oracle. All rights reserved. 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 Copyright (c) 2023, Oracle Corporation. All rights reserved. Oracle Home : /u01/app/oracle/product/19c/db_1 Central Inventory : /u01/oraInventory from : /u01/app/oracle/product/19c/db_1/oraInst.loc OPatch version : 12.2.0.1.36 OUI version : 12.2.0.7.0 Log file location : /u01/app/oracle/product/19c/db_1/cfgtoollogs/opatch/opatch2023-08-08_07-19-09AM_1.log Verifying environment and performing prerequisite checks... ......
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 $ORACLE_HOME/OPatch ./datapatch -verbose
8.ORACLE升级补丁查询
1.查询dba_server_registry视图
SQL> select comp_name,version from dba_server_registry;
2.查询dba_registry_history
SQL> select * from dba_registry_history;
3.查询product_component_version视图
SQL> select product,version from product_component_version;
4.查询v$version视图
SQL> select * from v$version;
