指南：记录19.3 RAC打补丁期间出现的一些问题：19.3升19.5、19.5升19.6。
新装的19.3 rac 需要安装补丁，目前最新的RU是19.6，由于最新的可能不稳定，选择了次新的19.5，打第一套比较顺利，后面的几套都出现些大大小小的问题 ，记录一下。
19.3存在一个比较严重的crs-6015错误，是个bug，在19.6得到了修复，我打完4套19.5，又重新打了遍19.6，比较坑，强列建议直接打19.6。
a）下载RU19.6补丁： ,包含GI、DB、OJVM 累积增量补丁。
b）补丁安装顺序：GI–>DB-OJVM。
c）打了19.5可以直接打19.6，不需要卸载。
d）打gi和db都是在root下面操作，只有ojvm需要在oracle用户下面操作。
一、补丁安装方法
1. 检查环境：
由于新装的，我这里就省略掉了，可以看README.html里面的方法.
2. 解压补丁包
我下载的是gi的RU，里面包含gi和db的补丁，我是解压到/tmp下面。
[root@xydb8node1 ~]# unzip -d /tm
[root@xydb8node1 ~]# chmod -R 777 /tm
3. 先打gi补丁【节点1打完，再打节点2】，使用opatchauto。
打gi要用gi_home的opatchauto，打oracle用oracle_home的opatchauto ,切记都是在root下面执行命令,这时用的是全路径，配置Path切换容易出错。
[root@xydb8node1 ~]# /u01/a apply /tm/30116789
4. 检查gi是否成功
[grid@xydb8node1 ~]$ /u01/a lspatches
30125133;Database Release Update : 19.5.0.0.191015 (30125133)
30122167;ACFS RELEASE UPDATE 19.5.0.0.0 (30122167)
30122149;OCW RELEASE UPDATE 19.5.0.0.0 (30122149)
29401763;TOMCAT RELEASE UPDATE 19.0.0.0.0 (29401763)
OPatch succeeded.
5. 打db补丁【节点1打完，再打节点2】，使用opatchauto。
[root@xydb8node1 ~]# /u01/app/oracle/produc apply /tm/30116789 -oh /u01/app/oracle/produc
6. 检查db是否成功
[oracle@xydb8node1 ~]$ /u01/app/oracle/produc/OPatch/opatch lspatches
30125133;Database Release Update : 19.5.0.0.191015 (30125133)
30122149;OCW RELEASE UPDATE 19.5.0.0.0 (30122149)
OPatch succeeded.
7. 打OJVM补丁【节点1打完，再打节点2】
[root@xydb8node1 ~]# cd /tm
[root@xydb8node1 30484981]# /u01/app/oracle/produc/OPatch/opatch apply
#按提示输入y,y即可。
8. 回退方法
#gi回退
/u01/a rollback /tmp/grid_path/30116789 -oh /u01/a
#db回退
/u01/app/oracle/produc rollback /tmp/grid_path/30116789 -oh /u01/app/oracle/produc
9. 小结
先打节点1，或2都行，没有强制要求先打节点1，习惯而已。补丁安装过程中可能会遇到各种权限问题及其它问题，后面针对遇到的问题都做了下记录，让后面的人少踩坑。
二、遇到的一些错误
错误No.1

问题描述:
DB补丁安装过程中报出的权限不足，具体原因不明，没有深入去分析,19c打补丁过程中会遇到各种权限问题。
解决办法:
[root@xydb8node1 ~]# chmod 777 /u01/app/oraInventory/ContentsXML
#resume是接着上次失败的地方继续安装的意思。
[root@xydb8node1 ~]# /u01/app/oracle/produc resume

故障现象：
集群能正常安装，安装完成后重启集群中其中一个节点可能会启不来，crs alert日志中抛出异常crs-6015 ，gipcInternalConnectSync: failed sync request 错误。
解决方法：
查询mos发现是个bug，测试在19.5中未进行修复，在最新19.6的RU中已进行了修复，所以新装的19.3 RAC 建议直接升级到19.6。

这个错误在正常打补丁过程中，如果shell断开，再重新执行命令会报这个错误。

opatchauto failed with error code 42
问题分析:
这个也是文件权限的问题，按要求设置权限就行。通过lspatches直接检查gi的版本，发现已经是19.6了，估计不改应该也行，我还是按要求来改了。
解决办法:
修改这2个文件的权限，继续resume，后续很可能遇到crs-6015错误。

问题分析:
到了这一步说明gi补丁已安装成功，在启动crs集群时卡住了，这里我为了完美打补丁，不强行ctrl+c 结束，想了个办法帮它重启crs。（这个错误是个bug，这里就不略过了）。
解决办法:
复制一个shell窗本，先停掉has,再启动has就行了，具体操作如下：
[root@xydb7node1 ~]# crsctl stop has -f
[root@xydb7node1 ~]# crsctl start has
等待一会，gi补丁就安装成功了，如下：
CRS service started successfully on home /u01/a
OPatchAuto successful.

总结
以上就是在整个19.3 rac 补丁安装过程中遇到的一些问题汇报，希望能有所帮助，crs-6015这个bug没想到在19.6才修复，前面几个ru也没处理，对于印象中高大上的Oracle来说，实属意外，需要加倍学习。最后感谢云和恩墨各位砖家的给力支持，谢谢。
