- 源端为备库的场景下Duplicate失败问题
我只在中间备库环境应用了PSU，解决了级联备库从中间备库duplicate数据库的问题：
细心的朋友已经发现，因为是备库环境，并没有做数据库执行相关脚本部分，所以如果去DB查询补丁应用信息是没有的：
代码语言：javascript复制SQL> r
1* select * from dba_registry_history

04-APR-23 04.37.58.780922 PM APPLY SERVER 11.2.0.3 0 PSU Patchset 11.2.0.2.0本篇文章就继续把级联备库以及主库的PSU软件补丁打上，步骤和上篇无区别，不再赘述。
最后要在主库按照readme执行对应脚本（只需在主库执行哦，通过ADG基理会将这些改变自动同步到备库）：
代码语言：javascript复制cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> STARTUP
SQL> @catbundle.sql psu apply
SQL> QUIT再次看状态：
代码语言：javascript复制set lines 1000
select * from dba_registry_history;
SQL> set lines 1000
