19c新環境安裝補丁

測試環境linux 2節點RAC19C 新環境安裝補丁比較簡單

RAC正常打補丁流程！

一.使用opatchauto opatchauto

1.節點1root執行會自動關閉當前節點db實例，自動打gi,oracle 軟件補丁

2.節點2root再執行;

3.最后數據庫執行應用腳本,補丁安裝完畢;

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

與11g版本相同

1.節點1 GI打

2.節點2 GI打

3.節點1 Oracle軟件打補丁

4.節點2 Oracle

5. DB執行腳本

 

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

=========================完畢！
1.本次測試環境打補丁不順利！
節點1執行，正常
[root@d2 ~]# /u01/app/19.0.0/grid/OPatch/opatchauto apply /u01/oracle/30464035
節點2執行，異常報錯

opatchauto failed with error code 42

參考解決方法，kill進程無法解決，因為這些進程除非關閉crs!

關閉crs在打補丁

關閉crs,打補丁無法使用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.

 

補丁回滾！

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

回滾失敗。導致集群節點2  crs無法啟動！

在打補丁的過程中，會對Lib等等進行備份修改，如果rollback失敗，將導致CRS無法啟動。
