AIX 6 Oracle RAC 11.2.0.4版本 PSU升級步驟
1.檢查/更新OPatch版本
官方要求OPatch版本需在11.2.0.3.6或以上，如果檢查OPatch版本低於11.2.0.3.6，需從官網下載最新OPatch實用程式，並在各個節點的database home和GI home均打上最新補丁。
| 在節點1和節點2檢查OPatch版本 [[email protected]:/home/grid]$ /app/11.2.0/grid/OPatch/opatch version [[email protected]:/home/oracle]$/app/oracle/product/11.2.0/db_1/OPatch/opatch version 分別替換節點1和節點2的OPatch Oracle使用者 # unzip p6880880_112000_AIX64-5L.zip # chown -R oracle:dba OPatch [[email protected]:/home/oracle]$ cd $ORACLE_HOME [[email protected]:/app/11.2.0/grid]$ mv OPatch OPatch_bak [[email protected]:/app/11.2.0/grid]$ mv /OPatch/OPatch $ORACLE_HOME [[email protected]:/app/11.2.0/grid Grid 使用者 # unzip p6880880_112000_AIX64-5L.zip # mv /app/11.2.0/grid/OPatch /app/11.2.0/grid/OPatch_bak #mv /OPatch/OPatch /app/11.2.0/grid/ # chown -R grid:install /oragrid/11.2.0/grid/OPatch [[email protected]:/home/grid]$/oragrid/11.2.0/grid/OPatch/opatch lsinventory |
2.生成OCM響應檔案
| 登陸grid使用者，在所有節點生成OCM響應檔案 $ORACLE_HOME/OPatch/ocm/bin/emocmrsp -no_banner -output /home/grid/ocm.rsp Provide your email address to be informed of security issues, install and initiate Oracle Configuration Manager. Easier for you if you use your My Oracle Support Email address/User Name. Visit http://www.oracle.com/support/policies.html for details. Email address/User Name:
You have not provided an email address for notification of security issues. Do you wish to remain uninformed of security issues ([Y]es, [N]o) [N]: y The OCM configuration response file (/home/grid/ocm.rsp) was successfully created. |
3.驗證Oracle補丁一致性
| 在所有節點的Grid和Oracle使用者執行： [[email protected]:/home/grid]$$ORACLE_HOME/OPatch/opatch lsinventory -detail -oh $ORACLE_HOME [[email protected]:/home/oracle]$ $ORACLE_HOME/OPatch/opatch lsinventory -detail -oh $ORACLE_HOME |
4.解壓Patch檔案
| # chown -R grid:dba /softwares/PSU [[email protected]:/softwares/PSU]$unzip p25476126_112040_AIX64-5L.zip |
5.停止EM
| As the Oracle RAC database home owner execute: [[email protected]:/home/oracle]$ $ORACLE_HOME/bin/emctl stop dbconsole |
6.安裝GI補丁
| 本環境由於GI Home和Database Home都沒使用共享，也沒有建立使用ACFS檔案，採用下面這種方式打補丁： 在所有節點root使用者下執行 # cd /softwares/PSU/25476126 # /oragrid/11.2.0/grid/OPatch/opatch auto /softwares/PSU/25476126 -ocmrf /home/grid/ocm.rsp 檢視日誌是由於無法建立$ORACLE_HOME/.patch_storage 許可權問題造成的無法建立 # chown grid:dba /oragrid/11.2.0/grid 重新執行# /oragrid/11.2.0/grid/OPatch/opatch auto /softwares/PSU/25476126 -ocmrf /home/grid/ocm.rsp
|
7.執行資料庫SQL補丁
| 這步在需在一個節點執行 Oracle 使用者 [[email protected]:/home/oracle]$ cd $ORACLE_HOME/rdbms/admin [[email protected]:/oraapp/app/oracle/rdbms/11g/rdbms/admin]$sqlplus /nolog SQL> CONNECT / AS SYSDBA SQL> @catbundle.sql psu apply SQL> QUIT [[email protected]:/home/oracle]$ cd $ORACLE_HOME/rdbms/admin [[email protected]:/oraapp/app/oracle/rdbms/11g/rdbms/admin]$sqlplus /nolog SQL> CONNECT / AS SYSDBA SQL> @utlrp.sql
Check the following log files in $ORACLE_BASE/cfgtoollogs/catbundle for any errors: catbundle_PSU_<database SID>_APPLY_<TIMESTAMP>.log catbundle_PSU_<database SID>_GENERATE_<TIMESTAMP>.log |
8.驗證補丁安裝情況
| 在grid和oracle使用者檢視 [[email protected]:/home/grid]$$ORACLE_HOME/OPatch/opatch lsinventory [[email protected]:/home/oracle]$$ORACLE_HOME/OPatch/opatch lsinventory 資料庫中執行： set linesize 200 set pagesize 200 col ACTION_TIME format a30 col ACTION format a10 col BUNDLE_SERIES format a15 col COMMENTS format a30 |
9.檢查叢集環境是否正常
| [[email protected]:/home/grid]$crsctl stat res -t |
10、回退方案
如升級過程出現重大問題導致升級無法正常進行，啟動緊急回退流程，執行回退方案，需嚴格按照如下步驟執行回退操作：
| 如果補丁安裝之後出現故障，則需回滾操作。 opatch auto <UNZIPPED_PATCH_LOCATION>/25476126 -rollback -ocmrf <ocm response file> 資料庫SQL回滾： cd $ORACLE_HOME/rdbms/admin sqlplus /nolog SQL> CONNECT / AS SYSDBA SQL> STARTUP SQL> @catbundle_PSU_<database SID PREFIX>_ROLLBACK.sql SQL> QUIT
cd $ORACLE_HOME/rdbms/admin sqlplus /nolog SQL> CONNECT / AS SYSDBA SQL> @utlrp.sql
在節點中檢查補丁是否回滾 [[email protected]:/home/grid]$$ORACLE_HOME/OPatch/opatch lsinventory [[email protected]:/home/oracle]$$ORACLE_HOME/OPatch/opatch lsinventory
