--更新opatch

https://updates.oracle.com/download/6880880.html Opatch下载地址

$ORACLE_HOME/OPatch/opatch version

$ORACLE_HOME/OPatch/opatch lspatches

chmod -R 777 /oracle/soft/p6880880_122010_Linux-x86-64.zip

--------------------------------oracle opatch

su - oracle

ls -ld $ORACLE_HOME/OPatch*

mv $ORACLE_HOME/OPatch $ORACLE_HOME/OPatch`date +\%Y\%m\%d`bak && cd /oracle/soft && unzip p6880880_122010_Linux-x86-64.zip -d $ORACLE_HOME

$ORACLE_HOME/OPatch/opatch version

RAC环境下无法在grid用户下直接执行，会报权限不足，需要root用户mv opatch

--------------------------------grid opatch

su - grid

ls -ld $ORACLE_HOME/OPatch*

cd $ORACLE_HOME/OPatch

pwd

su -

mv /oracle/app/12.2.0/grid/OPatch /oracle/app/12.2.0/grid/OPatch`date +\%Y\%m\%d`

unzip /oracle/soft/p6880880_122010_Linux-x86-64.zip -d /oracle/app/12.2.0/grid

chown -R grid:oinstall /oracle/app/12.2.0/grid/OPatch

su - grid

$ORACLE_HOME/OPatch/opatch version

3、备份程序

【备份软件】

su - root

mkdir -p /oracle/backup_soft

nohup tar -cvf /oracle/backup_soft/`date +\%Y\%m\%d`_oracle.tar            /oracle/app/oracle            >/oracle/backup_soft/`date +\%Y\%m\%d`_oracle.tar.log &

nohup tar -cvf /oracle/backup_soft/`date +\%Y\%m\%d`_12.2.0.tar            /oracle/app/12.2.0            >/oracle/backup_soft/`date +\%Y\%m\%d`_12.2.0.tar.log &

nohup tar -cvf /oracle/backup_soft/`date +\%Y\%m\%d`_grid.tar              /oracle/app/grid              >/oracle/backup_soft/`date +\%Y\%m\%d`_grid.tar.log &

nohup tar -cvf /oracle/backup_soft/`date +\%Y\%m\%d`_oraInventory.tar      /oracle/app/oraInventory      >/oracle/backup_soft/`date +\%Y\%m\%d`_oraInventory.tar.log &

nohup tar -cvf /oracle/backup_soft/`date +\%Y\%m\%d`_etc.tar               /etc                          >/oracle/backup_soft/`date +\%Y\%m\%d`_etc.tar.log &

4、使用opatchauto工具进行数据库升级

su – root

mkdir -p /oracle/soft/12c_patch

cd /oracle/soft/12c_patch

unzip /oracle/soft/p28980109_122010_Linux-x86-64.zip -d /oracle/soft/12c_patch

chmod -R 777 /oracle/soft/12c_patch

方法1：GI和DB分开打

【To patch only the GI home】

su - root

export UNZIPPED_PATCH_LOCATION=/oracle/soft/12c_patch/28980109

export GI_HOME=/oracle/app/12.2.0/grid

export PATH=$PATH:$GI_HOME/OPatch

opatchauto apply $UNZIPPED_PATCH_LOCATION/28828733 -oh $GI_HOME -analyze

opatchauto apply $UNZIPPED_PATCH_LOCATION/28828733 -oh $GI_HOME

【To patch only the DB home】

su - root

export UNZIPPED_PATCH_LOCATION=/oracle/soft/12c_patch/28980109

export ORACLE_HOME=/oracle/app/oracle/product/12.2.0/db_1

export PATH=$PATH:$ORACLE_HOME/OPatch

opatchauto apply $UNZIPPED_PATCH_LOCATION/28828733 -oh $ORACLE_HOME -analyze

opatchauto apply $UNZIPPED_PATCH_LOCATION/28828733 -oh $ORACLE_HOME

方法2：GI+DB一起打

su - root

export UNZIPPED_PATCH_LOCATION=/oracle/soft/12c_patch/28980109

export GI_HOME=/oracle/app/12.2.0/grid

export PATH=$PATH:$GI_HOME/OPatch

opatchauto apply $UNZIPPED_PATCH_LOCATION/28828733 -analyze

opatchauto apply $UNZIPPED_PATCH_LOCATION/28828733

--12C补丁列表信息

$ORACLE_HOME/OPatch/opatch version

$ORACLE_HOME/OPatch/opatch lspatches

$ORACLE_HOME/OPatch/opatch lsinventory

--检查数据字典中补丁信息

set lines 500 pages 500

col description for a80

col action_time for a35

col action for a10

col comments for a50

col VERSION for a20

col NAMESPACE for a20

col BUNDLE_SERIES for a20

select * from registry$history;

select patch_id,version,action,status,action_time,description from dba_registry_sqlpatch;

5、打OJVM补丁

【OJVM】

1、ojvm补丁检查

su - oracle

export PATCH_TOP_DIR=/oracle/soft/12c_patch/28980109

export PATH=$PATH:$ORACLE_HOME/OPatch

opatch prereq CheckConflictAgainstOHWithDetail -ph $PATCH_TOP_DIR/28790651

2、关闭所有服务（shut down all the services (database, ASM, listeners, nodeapps, and CRS daemons)

For an Oracle RAC environment, shut down all the services (database, ASM, listeners, nodeapps, and CRS daemons) running from the Oracle home on all the nodes you want to patch. su – root

/oracle/app/12.2.0/grid/bin/crsctl stop cluster -all -----停止所有节点集群服务

3、打OJVM补丁,所有节点都要打（OPatch is used on only one node at a time.）

su - oracle

export PATCH_TOP_DIR=/oracle/soft/12c_patch/28980109

export PATH=$PATH:$ORACLE_HOME/OPatch

cd $PATCH_TOP_DIR/28790651

$ORACLE_HOME/OPatch/opatch apply

$ORACLE_HOME/OPatch/opatch lspatches

$ORACLE_HOME/OPatch/opatch lsinventory

4、启服务 (After all nodes are patched, start all services. )

su – root

/oracle/app/12.2.0/grid/bin/crsctl start cluster -all -----启动所有节点集群服务

5、Loading Modified SQL Files Into the Database

1)Starting the Database for Post Installation Steps in an Oracle RAC Environment

On only one node, perform the following steps to start an Oracle RAC database in startup upgrade mode. 

sqlplus / as sysdba

SQL> startup 启动所有服务的时候数据库资源以及启动了

SQL> alter system set cluster_database=false scope=spfile;

$ORACLE_HOME/bin/srvctl stop database -d ndscdb

sqlplus / as sysdba

SQL> startup upgrade

2)

cd $ORACLE_HOME/OPatch

./datapatch -verbose  过程见下面

sqlplus / as sysdba

SQL> shutdown immediate;

3)Restarting the Database after Running the Post Installation Steps in an Oracle RAC Environment

To start the database back in normal mode

sqlplus / as sysdba

SQL> startup

SQL> alter system set cluster_database=true scope=spfile;

SQL> shutdown immediate;

$ORACLE_HOME/bin/srvctl start database -d ndscdb

6、失效对象

cd $ORACLE_HOME/rdbms/admin

sqlplus / as sysdba

SQL> @utlrp.sql

set lin 300 pages 5000

col object_name for a40

col owner for a20

select count(*) from dba_objects where status='INVALID';

select count(*) from dba_objects where status='INVALID' and owner='SYS';

select owner,object_name,object_type,status from dba_objects where status='INVALID';

7、检查数据字典中补丁信息

set lines 500 pages 500

col description for a75

col action_time for a35

col action for a10

col comments for a50

col VERSION for a25

col NAMESPACE for a20

col BUNDLE_SERIES for a20

select * from registry$history;

select patch_id,version,action,status,action_time,description from dba_registry_sqlpatch;
