Oracle 10g 應用補丁PSU 10.2.0.5.180717
最近測試了一下在 Oracle 10g 下面(單例項下面)升級、應用補丁 PSU 10.2.0.5.180717 ，打這個補丁的主要原因是 Oracle 將於 2019 年 6 月啟用新的 SCN 相容性，並且由於 BigSCN 的作用， 96K 每秒的 SCN 增速，都可能會使得通過 DB Link 的訪問產生 SCN 過度拉昇，所以新的補丁需要被應用。最近（ 2018 年 8 月份） Oracle 提供了針對 Oracle 10g 最終版本 10.2.0.5 的修正補丁，為低版本使用者提供了一個解決方案。更多這方面的相關知識，可以參考這篇文章 ofollow,noindex">升級更新:Oracle關於DB Link在2019年升級的10g版本相容性 。 下面按照官方文件從 Patch Pre-Installation Instructions,Patch Installation Instructions,Post Installation Instructions這三個方面來測試、驗證一下 。
Patch Pre-Installation Instructions
安裝這個補丁對 OPatch Utility 的版本有要求，要求 OPatch 10.2 version 10.2.0.5.0 或之後的版本，否則在應用補丁的過程就會遇到一些錯誤，後面例子會介紹這個具體錯誤，以及如何升級 OPatch Utility （此處不展開，後面展開）
檢查 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.
注意事項：
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 上下載 Patch 26493118 也就是 Oracle Database Patch Set Update 10.2.0.5.171017 。當然下載這個補丁是需要口令。 不過我們下載的是補丁程式 26493118: DATABASE PATCH SET UPDATE 10.2.0.5.171017 ， 因為我去下載的時候，這個補丁程式集已經被取代（ Patch 26925212 is a super set of patch 26493118 ）。
關閉監聽、 ORACLE 例項等 。
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服務是執行狀態，就必須關閉 $ emctl stop dbconsole
$ unzip p26925212_10205_Linux-x86-64.zip
解壓後，我們最好檢查一下當前環境是否存在補丁衝突
Determine whether any currently installed one-off patches conflict with the PSU patch as follows:
opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir ./26925212

如上所示，這個是因為 OPatch 的版本低於 10.2.0.5.0 ，所以必須必須先升級 OPatch 的版本，可以下載 p6880880_1020000_Linux-x86-64.zip 安裝包，具體步驟如下：
[oracle@mylnx01 tmp]$ unzip p6880880_1020000_Linux-x86-64.zip [oracle@mylnx01 tmp]$ cd OPatch/ [oracle@mylnx01 OPatch]$ cd $ORACLE_HOME [oracle@mylnx01 db_1]$ mv OPatch OPatch.bak [oracle@mylnx01 db_1]$ [oracle@mylnx01 db_1]$ cp -rf /tmp/OPatch/ ./ [oracle@mylnx01 db_1]$ ls -lrt ./OPatch total 80 -rw-r--r-- 1 oracle oinstall 2417 Nov 1 23:09 README.txt drwxr-xr-x 4 oracle oinstall 4096 Nov 1 23:09 opatchprereqs -rw-r--r-- 1 oracle oinstall 2576 Nov 1 23:09 opatch.pl -rw-r--r-- 1 oracle oinstall 49 Nov 1 23:09 opatch.ini -rwxr-xr-x 1 oracle oinstall 8085 Nov 1 23:09 opatch.bat -r-x--x--- 1 oracle oinstall 13252 Nov 1 23:09 opatch drwxr-xr-x 4 oracle oinstall 4096 Nov 1 23:09 ocm drwxr-xr-x 2 oracle oinstall 4096 Nov 1 23:09 jlib -rw-r--r-- 1 oracle oinstall 23695 Nov 1 23:09 emdpatch.pl drwxr-xr-x 2 oracle oinstall 4096 Nov 1 23:09 docs drwxr-xr-x 3 oracle oinstall 4096 Nov 1 23:09 crs [oracle@mylnx01 db_1]$ $ORACLE_HOME/OPatch/opatch version Invoking OPatch 10.2.0.5.1 OPatch Version: 10.2.0.5.1 OPatch succeeded.

打完補丁後，啟動 Oracle 例項，然後執行一些指令碼，如下所示，也可以參考補丁裡面的相關檔案 README.html
