12C(12201) RAC打补丁202004

12C（12201） RAC打补丁202004
RAC打补丁和单实例不太一样,要点：
1,打补丁前需要仔细阅读补丁集中的readme.html
2,补丁集给777权限，避免报错
3,opathauto需要用Root执行
4,需要集群软件启动crsctl start crs

# root设置变量 以ROOT权限执行(升级时设置的临时环境变量)
export ORACLE_BASE=/grid/app/grid
export ORACLE_HOME=/grid/app/12.2.0/grid
export PATH=$PATH:${ORACLE_HOME}/OPatch:${ORACLE_HOME}/bin

# 检查补丁冲突
# For Grid Infrastructure home, as home user:
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir <UNZIPPED_PATCH_LOCATION>/30920127/30886680
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir <UNZIPPED_PATCH_LOCATION>/30920127/30882603

$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir <UNZIPPED_PATCH_LOCATION>/30920127/30888810

# For database home, as home user:

### 检查空间是否足够
# For Grid Infrastructure home, as home user:
cat /tmp/patch_list_gihome.txt
<UNZIPPED_PATCH_LOCATION>/30920127/30886680
<UNZIPPED_PATCH_LOCATION>/30920127/30882603
<UNZIPPED_PATCH_LOCATION>/30920127/30869447
<UNZIPPED_PATCH_LOCATION>/30920127/26839277
<UNZIPPED_PATCH_LOCATION>/30920127/30888810

$ORACLE_HOME/OPatch/opatch prereq CheckSystemSpace -phBaseFile /tmp/patch_list_gihome.txt

# For database home, as home user
cat /tmp/patch_list_dbhome.txt
<UNZIPPED_PATCH_LOCATION>/30920127/30886680
<UNZIPPED_PATCH_LOCATION>/30920127/30882603

$ORACLE_HOME/OPatch/opatch prereq CheckSystemSpace -phBaseFile /tmp/patch_list_dbhome.txt

# 应用补丁(会自动在grid,oracle用户的ORACLE_HOME应用补丁，如果是GI补丁的话，可以不用需要DB的补丁，GI的补丁中包含了DB的补丁)
opatchauto apply /software/patch2020/30920127 -analyze
opatchauto apply /software/patch2020/30920127

# 查看应用之后的补丁情况

遇到问题描述： This command doesn’t support System Patch.
12201版本更新2020的补丁
下载最新的opatch工个，解压p6880… 之后使用opatch version查看应用情况：
报错This command doesn’t support System Patch.
原因：下载的是linux的版本，当前版本是linux x86_64版本不匹配
解决方法：重新下载x64_64的版本。
