ADG级联备库环境PSU应用验证

上篇文章

• 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：

SQL> r
  1*  select * from dba_registry_history

ACTION_TIME                   ACTION         NAMESPACE        VERSION        ID BUNDLE_SERIES      COMMENTS
--------------------------------------------------------------------------- ------------------------------ ------------------------------ ------------------------------ ---------- ------------------------------ ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
17-SEP-11 10.21.11.595816 AM                APPLY        SERVER       11.2.0.3          0 PSU          Patchset 11.2.0.2.0
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）：

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：

set lines 1000
select * from dba_registry_history;

SQL> set lines 1000
select * from dba_registry_history;SQL>

ACTION_TIME                   ACTION         NAMESPACE        VERSION        ID BUNDLE_SERIES      COMMENTS

最后去备库，以及级联备库分别确认同步状态：

备库状态：已有11.2.0.3.15信息

[oracle@db11gadg ~]$

级联备库状态：在主库切日志后也会有11.2.0.3.15信息：

都没问题了，整个过程也符合PSU补丁应用逻辑。
