Oracle数据库异机升级

时间 2019-11-19

原文原文链接

环境：
A机：RHEL5.5 + Oracle 10.2.0.4
B机：RHEL5.5
需求：
A机10.2.0.4数据库，在B机升级到11.2.0.4，应用最新PSU补丁程序。
目录：
1、确认是否能够直接升级
2、 B机安装11g软件，打好PSU补丁
3、 B机环境变量检查
4、 B机建立须要的目录
5、 A机原库升级前检查html

6、 A机备份原库
7、 B机恢复数据库
8、 B机升级数据库sql

9、 B机升级后操做数据库

1、确认是否能够直接升级

本次需求：Oracle 10.2.0.4 -> 11.2.0.4.7
从下图中看到，能够直接升级。

网络

2、 B机安装11g软件，打好PSU补丁

安装11g软件(不须要建库)可参考： http://www.cnblogs.com/jyzhao/p/3891769.html
打PSU补丁(补丁随带的readme必须看)可参考： http://www.cnblogs.com/jyzhao/p/4145273.html

3、 B机环境变量检查

echo $ORACLE_BASE
echo $ORACLE_HOME
echo $ORACLE_SID
echo $PATH

4、 B机建立须要的目录

B机建议先建立如下目录，其中scripts不是必须的，对于bdump,udump在11g再也不须要了，这点从后面的升级前检查脚本的输出结果也可看到。oracle

mkdir -p $ORACLE_BASE/admin/$ORACLE_SID/adump
mkdir -p $ORACLE_BASE/admin/$ORACLE_SID/dpdump 
mkdir -p $ORACLE_BASE/admin/$ORACLE_SID/cdump 
mkdir -p $ORACLE_BASE/admin/$ORACLE_SID/pfile 
mkdir -p $ORACLE_BASE/admin/$ORACLE_SID/scripts

5、 A机原库升级前检查

将B机11.2.0.4的utlu112i.sql，scp到A机上，进行升级检查。
app

5.1 从B机上传utlu112i.sql脚本到A机

$ scp $ORACLE_HOME/rdbms/admin/utlu112i.sql 192.168.xx.xx:/home/oracle

5.2 A机执行utlu112i.sql进行升级前检查

Miscellaneous Warnings
**********************************************************************
WARNING: --> Database is using a timezone file older than version 14.
.... After the release migration, it is recommended that DBMS_DST package
.... be used to upgrade the 10.2.0.4.0 database timezone version
.... to the latest version which comes with the new release.
WARNING: --> Database contains INVALID objects prior to upgrade.
.... The list of invalid SYS/SYSTEM objects was written to
.... registry$sys_inv_objs.
.... The list of non-SYS/SYSTEM objects was written to
.... registry$nonsys_inv_objs.
.... Use utluiobj.sql after the upgrade to identify any new invalid
.... objects due to the upgrade.
.... USER CRNOPHQOA has 2 INVALID objects.
WARNING: --> EM Database Control Repository exists in the database.
.... Direct downgrade of EM Database Control is not supported. Refer to the
.... Upgrade Guide for instructions to save the EM data prior to upgrade.
WARNING: --> Your recycle bin is turned on and currently contains no objects.
.... Because it is REQUIRED that the recycle bin be empty prior to upgrading
.... and your recycle bin is turned on, you may need to execute the command:
        PURGE DBA_RECYCLEBIN
.... prior to executing your upgrade to confirm the recycle bin is empty.
WARNING: --> JOB_QUEUE_PROCESS value must be updated
.... Your current setting of "10" is too low.

.... Starting with Oracle Database 11g Release 2 (11.2), setting
.... JOB_QUEUE_PROCESSES to 0 causes both DBMS_SCHEDULER and
.... DBMS_JOB jobs to not run. Previously, setting JOB_QUEUE_PROCESSES
.... to 0 caused DBMS_JOB jobs to not run, but DBMS_SCHEDULER jobs were
.... unaffected and would still run. This parameter must be updated to
.... a value greater than 32  (default value is 1000) prior to upgrade.
.... Not doing so will affect the running of utlrp.sql after the upgrade
.
**********************************************************************
Recommendations
**********************************************************************
Oracle recommends gathering dictionary statistics prior to
upgrading the database.
To gather dictionary statistics execute the following command
while connected as SYSDBA:

    EXECUTE dbms_stats.gather_dictionary_stats;

5.3 根据检查结果调整A机数据库

5.3.1 表空间对比知足条件

select file_name,tablespace_name,maxbytes/1024/1024 from dba_data_files
where tablespace_name in('SYSTEM','UNDOTBS1','SYSAUX')
union all
select file_name,tablespace_name,maxbytes/1024/1024 from dba_temp_files;

5.3.2 A机建立pfile文件

SQL> create pfile='/home/oracle/orcl10.pfile' from spfile;

5.3.3 A机scp pfile文件到B机

$ scp /home/oracle/orcl10.pfile 192.168.xx.xx:/home/oracle

5.3.4 B机上编辑pfile文件

注意下sga和pga的设定是否符合目的机器的配置
*.sga_target=629145600
*.pga_aggregate_target=25165824
将*.background_dump_dest和*.user_dump_dest删除
加上 *.diagnostic_dest='$ORACLE_BASE'
注：参数文件的修改不用多说，但须要注意其余各参数的值是否符合需求。

修改后复制一份到$ORACLE_HOME/dbs/init$ORACLE_SID.oraide

$ cp /home/oracle/orcl10.pfile $ORACLE_HOME/dbs/init$ORACLE_SID.ora

5.3.5 A机运行utlrp.sql 脚本，从新编译无效对象

从新编译SYS 和SYSTEM 中的无效对象工具

记录无效对象：
col OWNER for a10;
col OBJECT_NAME for a30;
col OBJECT_TYPE for a10;
select * from registry$nonsys_inv_objs; //非sys/system的失效对象

select * from registry$sys_inv_objs;   //sys/system的失效对象
 
SQL> @?/rdbms/admin/utlrp.sql;
从新执行 @/home/oracle/utlu112i.sql，查看是否从新编译,

5.3.6 A机执行PURGE DBA_RECYCLEBIN

SQL> PURGE DBA_RECYCLEBIN;
DBA Recyclebin purged.

5.3.7 A机收集系统信息EXECUTE dbms_stats.gather_dictionary_stats;

在升级前收集字典统计信息，不然预升级工具( utlu102i.sql)会花费更长时间测试

SQL> EXECUTE dbms_stats.gather_dictionary_stats;
 
PL/SQL procedure successfully completed.

注意：升级以后执行utluiobj.sqlui

6、 A机备份原库

为了避免影响业务的网络带宽，可采用DCN网络进行NFS的搭建，同时没必要再传送备份文件。
NFS配置参考：http://www.cnblogs.com/jyzhao/p/3809078.html
A机备份原库可参考：http://www.cnblogs.com/jyzhao/p/4806434.html#1

7、 B机恢复数据库

B机恢复数据库可参考： http://www.cnblogs.com/jyzhao/p/4806434.html#2

注意：这里恢复完成不要直接尝试打开数据库。由于咱们是要升级！须要open resetlogs upgrade（在下一个步骤说明）。

8、 B机升级数据库

8.1 修改恢复后的数据库为非归档模式

为预防升级测试过程当中默认的归档空间不够，这里升级先把库开启为非归档模式。

SQL> select status from v$instance;

STATUS
------------
MOUNTED

SQL> alter database noarchivelog;

Database altered.

SQL> archive log list
Database log mode              No Archive Mode
Automatic archival             Disabled
Archive destination            USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     27
Current log sequence           29

8.2 alter database open resetlogs upgrade;

SQL> alter database open resetlogs upgrade;

8.3 执行升级脚本

SQL> spool upgrade.log
SQL> @?/rdbms/admin/catupgrd.sql

本次升级经验值：
测试库此步骤升级运行时间：37分钟。
生产库此步骤升级运行时间：61分钟。

9、 B机升级后操做

9.1 建立spfile文件

SQL> startup pfile='$ORACLE_HOME/dbs/init$ORACLE_SID.ora'
SQL> create spfile from pfile='$ORACLE_HOME/dbs/init$ORACLE_SID.ora';

9.2 执行EXECUTE dbms_stats.gather_dictionary_stats;

SQL> exec dbms_stats.gather_dictionary_stats;
PL/SQL procedure successfully completed.

9.3 从新编译

SQL> @?/rdbms/admin/utlrp.sql

9.4 查看失效对象

SQL> SELECT count(*) FROM dba_invalid_objects;

若是失效对象为升级以前的失效对象，升级过程当中没有使对象失效。

9.5 运行升级后检查脚本

SQL> @?/rdbms/admin/utlu112s.sql

9.6 数据库层面应用PSU

cd $ORACLE_HOME/rdbms/admin/
SQL> @catbundle.sql psu apply

检查opatch补丁相关信息：

./opatch lspatches
./opatch lsinventory

查询dba_registry_history:

SQL> select * from dba_registry_history;

到此，已完成数据库异机升级操做。
