Oracle 10g 应用补丁PSU 10.2.0.5.180717

Posted 2021-01-17

 

最近测试了一下在Oracle 10g下面(单实例下面)升级、应用补丁PSU 10.2.0.5.180717，打这个补丁的主要原因是 Oracle 将于 2019年6月启用新的SCN兼容性，并且由于BigSCN的作用，96K每秒的SCN增速，都可能会使得通过DB Link的访问产生SCN过度拉升，所以新的补丁需要被应用。最近（2018年8月份）Oracle 提供了针对 Oracle 10g 最终版本 10.2.0.5 的修正补丁，为低版本用户提供了一个解决方案。更多这方面的相关知识，可以参考这篇文章升级更新:Oracle关于DB Link在2019年升级的10g版本兼容性。下面按照官方文档从Patch Pre-Installation Instructions,Patch Installation Instructions,Post Installation Instructions这三个方面来测试、验证一下。

 

 

 

Patch Pre-Installation Instructions

 

 

安装这个补丁对OPatch Utility的版本有要求，要求OPatch 10.2 version 10.2.0.5.0 或之后的版本，否则在应用补丁的过程就会遇到一些错误，后面例子会介绍这个具体错误，以及如何升级OPatch Utility（此处不展开，后面展开）

 

 

 

检查opatch版本

 

 

不符合要求的版本的例子：

 

#$ORACLE_HOME/OPatch/opatch version

Invoking OPatch 10.2.0.4.9

OPatch Version: 10.2.0.4.9

OPatch succeeded.

 

 

符合要求的版本的例子：

 

#$ORACLE_HOME/OPatch/opatch version

Invoking OPatch 10.2.0.5.1

OPatch Version: 10.2.0.5.1

OPatch succeeded.

 

 

 

注意事项：

 

To install the PSU 10.2.0.5.180717 patch, the Oracle home must have the 10.2.0.5.0 Database installed. Subsequent PSU patches can be installed on Oracle Database 10.2.0.5.0 or any PSU with a lower 5th numeral version than the one being installed.

 

 

 

首先要去meatalink上下载Patch 26493118 也就是 Oracle Database Patch Set Update 10.2.0.5.171017。当然下载这个补丁是需要口令。不过我们下载的是补丁程序26493118: DATABASE PATCH SET UPDATE 10.2.0.5.171017， 因为我去下载的时候，这个补丁程序集已经被取代（Patch 26925212 is a super set of patch 26493118）。

 

 

关闭监听、ORACLE实例等。

 

如下所示：

 

$ lsnrctl stop

SQL> shutdown immediate

$ emctl status dbconsole

TZ set to PRC

OC4J Configuration issue. /u01/app/oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_getlnx14uat.esquel.com_SCM2 not found. 

如果EM服务是运行状态，就必须关闭

$ emctl stop dbconsole

 

 

$ unzip p26925212_10205_Linux-x86-64.zip

 

解压后，我们最好检查一下当前环境是否存在补丁冲突

 

   Determine whether any currently installed one-off patches conflict with the PSU patch as follows:

 

opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir ./26925212

 

 

正常情况：

 

[oracle@mylnx01 klb]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir ./26925212/
