Invoking prereq "checkconflictagainstohwithdetail"

Prereq "checkConflictAgainstOHWithDetail" failed.

The details are:

Interim patch 31064025 requires prerequisite patch(es) [31281355] which are not present in the Oracle Home.

Apply prerequisite patch(es) [31281355] before applying interim patch 31064025.

Summary of Conflict Analysis:

There are no patches that can be applied now.

OPatch succeeded.

检查的时候发现问题了，要先打这个31281355，又去MOS上下载有关这个的 p31281355_190000_Linux-x86-64.zip包，在31281355的readme里面发现，我的数据库的opatch的版本过低，还要下载opatch。

patch 6880880

安装opatch 没有留记录，可以参考mos上的

安装完成opatch后，重新检查版本冲突。

[oracle@oadb1 OPatch]$ ./opatch version

OPatch Version: 12.2.0.1.21

OPatch succeeded.

重新检查版本冲突

[oracle@oadb1 backup]$ cd 31281355

补丁安装

以31281355补丁安装为例，根据补丁安装程序提供的README.txt，利用滚动式打补丁，具体安装步骤如下：

步骤	描述
	停所有监听(根据每个节点查询结果调整)、杀进程： $ su - grid $ ps -ef\|grep lsnr $ lsnrctl stop listener $ su - oracle $ ps -ef\|grep LOCAL=NO\|grep -v grep\|awk '{print $2}'\|xargs kill -9
	停实例： SQL>shutdown immediate
	停crs： $ su - root $ /u01/app/19.0.0/grid/bin/crsctl stop crs
	补丁安装： $ cd /backup/31281355 $ /u02/app/oracle/product/19.0.0/db_1/OPatch/opatch apply
	检查验证： /u02/app/oracle/product/19.0.0/db_1/OPatch/opatch lsinventory
	起crs； $ su - root $ crsctl start crs
	起实例； $srvctl start database -d
	查看每个节点实际状况调整： $su - grid $ /u01/app/19.0.0/grid/bin/crsctl status res -t

在二节点重复上面的步骤都成功后再打 p31064025_198000DBRU_Linux-x86-64.zip

补丁回退
