13.4 OPatch冲突检测

#GI

/app/product/19.3.0/crs/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /app/media/19.23/36233126/36233263 /app/product/19.3.0/crs/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /app/media/19.23/36233126/36240578 /app/product/19.3.0/crs/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /app/media/19.23/36233126/36233343 /app/product/19.3.0/crs/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /app/media/19.23/36233126/36460248 /app/product/19.3.0/crs/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /app/media/19.23/36233126/36383196

13.1.8 OPatch冲突，回滚冲突的patch

示例：并非36233126出现冲突

Composite Patch : 34386266 Conflict with 19509982 Detail Conflicts/Supersets for each patch are: Sub-Patch : 31550110 Conflict with 19509982 Conflict details: /u01/app/oracle/product/12.1.0/db_1/lib/libserver12.a:qksbg.o /u01/app/oracle/product/12.1.0/db_1/lib/libserver12.a:qksfm.o /u01/app/oracle/product/12.1.0/db_1/lib/libserver12.a:qkscr.o

grid用户执行：/app/product/19.3.0/crs/OPatch/opatchauto rollback /app/media/19.23/36233126 -analyze

13.5 OPatch空间检查（两节点）

#GI

vi /tmp/patch_list_gihome.txt

/app/media/19.23/36233126/36233263 /app/media/19.23/36233126/36240578 /app/media/19.23/36233126/36233343 /app/media/19.23/36233126/36460248 /app/media/19.23/36233126/36383196

grid用户执行：/app/product/19.3.0/crs/OPatch/opatch prereq CheckSystemSpace -phBaseFile /tmp/patch_list_gihome.txt

#ORACLE

vi /tmp/patch_list_dbhome.txt

/app/media/19.23/36233126/36233263 /app/media/19.23/36233126/36240578

oracle执行：/app/oracle/product/19.3.0/dbhome_1/OPatch/opatch prereq CheckSystemSpace -phBaseFile /tmp/patch_list_dbhome.txt

14 OPatch安装前检查（两节点）

chown -R grid.oinstall /app/tmp

grid用户执行：cluvfy stage -pre patch

14.1 安装前查看OPatch情况（两节点）

#GI

/app/product/19.3.0/crs/OPatch/opatch lspatches

#ORACLE

/app/oracle/product/19.3.0/dbhome_1/OPatch/opatch lspatches

14.2 oraInventory目录增加组权限（两节点）

chmod 777 /app/oraInventory

停止集群（root执行，两节点） --- 此步无需执行，opatchauto会报错

[root@pri01 ~]# /app/product/19.3.0/crs/bin/crsctl stop crs

/app/product/19.3.0/crs/bin/crsctl stop cluster -all

15 自动安装patch（两节点）

官方文档中明确说明，两节点执行

The utility must be executed by an operating system (OS) user with root privileges, and it must be executed on each node in the cluster if the Grid home or Oracle RAC database home is in non-shared storage. The utility can be run in parallel on the cluster nodes except for the first (any) node.

#安装过程中注意关闭其他ssh远程连接。

root用户执行以下命令：

cd /app/product/19.3.0/crs/OPatch export PATH=$PATH:/app/product/19.3.0/crs/OPatch

/app/product/19.3.0/crs/OPatch/opatchauto apply /app/media/19.23/36233126

报错后，执行以下命令（两节点）

安装GI时，export PATH=$PATH:/app/product/19.3.0/crs/OPatch

安装DB时，export PATH=$PATH:/app/oracle/product/19.3.0/dbhome_1/OPatch

#To patch only the Grid home:

/app/product/19.3.0/crs/OPatch/opatchauto apply /app/media/19.23/36233126 -oh /app/product/19.3.0/crs/

#To patch one Oracle RAC database homes:

/app/oracle/product/19.3.0/dbhome_1/OPatch/opatchauto apply /app/media/19.23/36233126 -oh /app/oracle/product/19.3.0/dbhome_1

16 验证RU

16.1 验证patch安全性（两节点）

grid用户执行：cluvfy stage -post patch

16.2 安装后查看OPatch情况（两节点）

#GI

/app/product/19.3.0/crs/OPatch/opatch lspatches

#ORACLE

/app/oracle/product/19.3.0/dbhome_1/OPatch/opatch lspatches

16.3 编译无效对象

非CDB/PDB环境

sqlplus / as sysdba

@?/rdbms/admin/utlrp.sql

CDB/PDB环境

/app/oracle/product/19.3.0/dbhome_1/perl/bin/perl /app/oracle/product/19.3.0/dbhome_1/rdbms/admin/catcon.pl -n 1 -e -b utlrp -d /app/oracle/product/19.3.0/dbhome_1/rdbms/admin utlrp.sql

注：由于使用opatchauto，无需执行/app/oracle/product/19.3.0/dbhome_1/OPatch/datapatch -verbose

16.4 验证数据字典

select ACTION_TIME,VERSION,COMMENTS from dba_registry_history;

select patch_id,patch_type,action,status,action_time,description from dba_registry_sqlpatch;

至此19c RAC的RU配置完成
