Oracle RAC 应用PSU

一、备份数据库
采用RMAN或expdp均可以。
二、备份软件目录（node1/2）

tar -czvf /u01/grid.tar.gz  /u01/app/11.2.0/grid  --exclude=/u01/app/11.2.0/grid/rdbms/audit/*
tar -czvf /u01/database.tar.gz /u01/app/oracle/  --exclude=/u01/app/oracle/admin/orcl/adump/*

三、备份OCR（node1/2）

[grid@vastdata01 ~]$ cd $ORACLE_HOME/bin
[grid@vastdata01 bin]$ pwd
/u01/app/11.2.0/grid/bin
./crsctl query css votedisk
./ocrcheck
./ocrconfig -manualbackup
./ocrconfig -export ocr.bak

四、备份OLR（node1/2）

[grid@vastdata01 ~]$tar -cf /home/oracle/backup/ocr/olr.tar /u01/app/11.2.0/grid/cdata

五、升级前数据库对象检查

检查失效对象
    select object_name,object_type from dba_objects where status='INVALID';
检查正在运行的job
    select job,this_date,last_date,instance from dba_jobs_running;
中止关于数据库的crontab任务
    crontab –l
    crontab -e
检查计划job
    col job_name for a10;
    col owner for a10;
    col start_date for a20;
    col end_date for a20;
    col repeat_interval for a10;
    set linesize 2000
    set pagesize 2000
    select job_name,owner,start_date,end_date,repeat_interval from dba_scheduler_jobs;
查看计划dba 计划job
    col interval for a20
    col what for a30
    set linesize 2000 pagesize 2000
    select schema_user,job,interval,what from dba_jobs;
    show parameter job_queue
查看自动执行任务
    select client_name,job_name,task_name from dba_autotask_client_job;

六、关闭数据库与集群

中止监听 lsnrctl stop
        中止数据库 shutdown immediate;
        中止集群 crsclt stop crs

七、关闭 EM 代理进程（oracle，每一个节点）

cd $ORACLE_HOME/bin
./emctl stop dbconsole

八、建立OCM文件（node1/2）

[grid@vastdata01 ~]$  cd /u01/app/11.2.0/grid/OPatch/ocm/bin/
[grid@vastdata01 bin]$ ./emocmrsp

九、创建补丁存放目录

十、备份与替换OPatch

十一、补丁更改权限

chown -R grid:oinstall psu
ps -ef|grep zjprd1|grep LOCAL=NO|grep -v grep|awk '{print $2}'| xargs kill -9
/usr/sbin/slibclean-----AIX须要手动清理
注意：/tmp和/目录至少有10G的空间

十二、应用补丁

root
/oracle/grid/crs/install/rootcrs.pl -unlock

GI
/oracle/grid/OPatch/opatch napply -oh /oracle/grid/  -local  /quest/psu/17592127   
/oracle/grid/OPatch/opatch apply -oh /oracle/grid/  -local  /quest/psu/20760997

DB
su - oracle
/quest/psu/17592127/custom/server/17592127/custom/scripts/prepatch.sh -dbhome  /oracle/app/oracle/product/11.2.0/db_1/
/oracle/app/oracle/product/11.2.0/db_1/OPatch/opatch napply -oh $ORACLE_HOME  -local  /quest/psu/17592127/custom/server/17592127
/oracle/app/oracle/product/11.2.0/db_1/OPatch/opatch apply -oh $ORACLE_HOME  -local  /quest/psu/20760997
/quest/psu/17592127/custom/server/17592127/custom/scripts/postpatch.sh -dbhome  /oracle/app/oracle/product/11.2.0/db_1/

root
/oracle/grid/rdbms/install/rootadd_rdbms.sh
/oracle/grid/crs/install/rootcrs.pl -patch
chown oracle:asmadmin $ORACLE_HOME/bin/oracle
chmod 6751 $ORACLE_HOME/bin/oracle

1三、检查

su - grid
$ORACLE_HOME/OPatch/opatch lspatches
exit
su - oracle
cd $ORACLE_HOME/rdbms/admin
sqlplus / as sysdba
@catbundle.sql psu apply
select * from registry$history;
