简单描述如何检查当前数据库的CPU和PSU补丁安装情况。
正常情况下有两种方法，一种是登录数据库检查DBA_REGISTRY_HIST视图：
- MODDB2:[/home/oracle]$sqlplus / as sysdba
- SQL*Plus: Release 10.2.0.4.0 - Production on Thu Aug 18 13:04:43 2011
- Copyright (c) 1982, 2007, Oracle. All Rights Reserved.
- Connected to:
- Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
- With the Partitioning, Real Application Clusters, Oracle Label Security, Data Mining
- and Real Application Testing options
- SQL> set pages 100 lines 120
- SQL> col action format a6
- SQL> col namespace format a10
- SQL> col version format a10
- SQL> col comments format a15
- SQL> col action_time format a30
- SQL> col bundle_series format a15
- SQL> alter session set nls_timestamp_format = 'yyyy-mm-dd hh24:mi:ss.ff';
- Session altered.
- SQL> select * from dba_registry_history;
- ACTION_TIME ACTION NAMESPACE VERSION ID BUNDLE_SERIES COMMENTS
- --------------------------- ------ ---------- ---------- ---- -------------- ---------------
- 2011-06-02 16:54:21.301023 APPLY SERVER 10.2.0.4 4 PSU PSU 10.2.0.4.4
- 2011-06-02 16:54:42.711877 APPLY SERVER 10.2.0.4 1 OPSU PSU 10.2.0.4.5
另一种方式是通过opatch lsinventory方式：
- MODDB2:[/home/oracle]$opatch lsinventory
- Invoking OPatch 10.2.0.5.0
- Oracle Interim Patch Installer version 10.2.0.5.0
- Copyright (c) 2010, Oracle Corporation. All rights reserved.
- Oracle Home : /oracle/db
- Central Inventory : /oracle/oraInventory
- from : /var/opt/oracle/oraInst.loc
- OPatch version : 10.2.0.5.0
- OUI version : 10.2.0.4.0
- OUI location : /oracle/db/oui
- Log file location : /oracle/db/cfgtoollogs/opatch/opatch2011-08-18_11-18-30AM.log
- Patch history file: /oracle/db/cfgtoollogs/opatch/opatch_history.txt
- Lsinventory Output file location : /oracle/db/cfgtoollogs/opatch/lsinv/lsinventory2011-08-18_11-18-30AM.txt
- --------------------------------------------------------------------------------
- Installed Top-level Products (2):

- OPatch succeeded.
注意，CPU和PSU补丁分为两部分，首先通过opatch命令，随后还需要运行cat_bundle.sql。如果没有运行这个SQL，则补丁不算安装成功，这时通过OPATCH命令检查可以看到补丁的安装信息，但是在数据库的DBA_REGISTRY_HISTORY中是找不到对应的信息的。
