19c新环境安装补丁

测试环境linux 2节点RAC19C 新环境安装补丁比较简单

RAC正常打补丁流程！

一.使用opatchauto opatchauto

1.节点1root执行会自动关闭当前节点db实例，自动打gi,oracle 软件补丁

2.节点2root再执行;

3.最后数据库执行应用脚本,补丁安装完毕;

二.使用opatchauto opatchauto -oh $ORACLE_HOME OR $GRID_HOME 

与11g版本相同

1.节点1 GI打

2.节点2 GI打

3.节点1 Oracle软件打补丁

4.节点2 Oracle

5. DB执行脚本

正常流程
A

[root@d1 ~]# /u01/app/19.0.0/grid/OPatch/opatchauto apply /u01/oracle/30464035

[root@d2 ~]# /u01/app/19.0.0/grid/OPatch/opatchauto apply /u01/oracle/30464035

su - oracle

alter pluggable database all open

cd $ORACLE_HOME/OPatch

./datapatch -verbose

or

B

node1 root, node2 root

/u01/app/19.0.0/grid/OPatch/opatchauto apply /u01/oracle/30464035 -oh /u01/app/19.0.0/grid

/u01/app/19.0.0/grid/OPatch/opatchauto apply /u01/oracle/30464035 -oh /u03/app/oracle/product/19.0.0/db_1

su - oracle

alter pluggable database all open

cd $ORACLE_HOME/OPatch

./datapatch -verbose

=========================完毕！
1.本次测试环境打补丁不顺利！
节点1执行，正常
[root@d2 ~]# /u01/app/19.0.0/grid/OPatch/opatchauto apply /u01/oracle/30464035
节点2执行，异常报错

opatchauto failed with error code 42

参考解决方法，kill进程无法解决，因为这些进程除非关闭crs!

关闭crs在打补丁

关闭crs,打补丁无法使用opatchauto！
# /u01/app/19.0.0/grid/bin/crsctl stop crs -f
[root@d2 ~]# /u01/app/19.0.0/grid/bin/crsctl start crs
ManualSteps for Apply/Rollback Patch
See My Oracle Support Document 2246888.1for cases where opatchauto cannotbe used.

补丁回滚！

[grid@d2:/u01/oracle/30464035]$ /u01/app/19.0.0/grid/OPatch/opatch rollback -id 30446054

回滚失败。导致集群节点2  crs无法启动！

在打补丁的过程中，会对Lib等等进行备份修改，如果rollback失败，将导致CRS无法启动。
