10.2.0.4升级到11.2.0.3(单机)

下面是应群ORACLE数据库超级群 里一位网友的要求,把10.2.0.4升级到11.2.0.3的笔记发出来,这里只写了升级与降级时跑脚本的步骤,更多相关文档请参考MOS文件。

如何从数据库 11.2 降级至之前的版本(包括 11.2.0.4-11.2.0.1) (Doc ID 1525777.1)
complete Checklist for Manual Upgrades to 11gR2 [ID 837570.1]

其实数据库的升级步骤是很简单的,只是在升级前的测试与升级后业务的支持比较复杂,比如:升级后面SQL性能的变化等等。

1,运行utlu112i脚本,用于检查10.2.0.4升级到11.2.0.3需要注意或者修改的地方

特别是需要注意的是在源旧的环境中执行需要升级到的版本下的utlu112i.sql脚本,并注意观察一些警告与错误信息

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 SCOTT has 1 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.
.
**********************************************************************
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;

**********************************************************************
Oracle recommends removing all hidden parameters prior to upgrading.

To view existing hidden parameters execute the following command
while connected AS SYSDBA:

    SELECT name,description from SYS.V$PARAMETER WHERE name
        LIKE '\_%' ESCAPE '\'

Changes will need to be made in the init.ora or spfile.

**********************************************************************
Oracle recommends reviewing any defined events prior to upgrading.

To view existing non-default events execute the following commands
while connected AS SYSDBA:
  Events:
    SELECT (translate(value,chr(13)||chr(10),' ')) FROM sys.v$parameter2
      WHERE  UPPER(name) ='EVENT' AND  isdefault='FALSE'

  Trace Events:
    SELECT (translate(value,chr(13)||chr(10),' ')) from sys.v$parameter2
      WHERE UPPER(name) = '_TRACE_EVENTS' AND isdefault='FALSE'

Changes will need to be made in the init.ora or spfile.

**********************************************************************
这里有一些警告的东西,有部分参数在11G环境也不受支持,所以更改一下。关闭数据库
www.htz.pw > shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
www.htz.pw > exit

2,切换环境到11.2.0.3

这里需要将参数文件,tnsnames.ora文件,listener.ora文件,密码文件复制到新环境中,如果两个环境的属主不一致的时候,我们需要注意权限

[oracle@www.htz.pw oradata]$cp orcl1024 /soft -R
[oracle@www.htz.pw oradata]$cp /oracle/app/oracle/product/10.2.0/db_1024/dbs/spfileorcl1024.ora /tmp
[oracle@www.htz.pw oradata]$source ~/.1123
[oracle@www.htz.pw oradata]$cp /tmp/spfileorcl1024.ora $ORACLE_HOME/dbs
[oracle@www.htz.pw oradata]$export ORACLE_SID=orcl1024

3,运行catupgrd脚本

这里需要注意的是catupgrd.sql脚本运行完后,会自动的关闭数据库。

oracle@www.htz.pw oradata]$sqlplus / as sysdba
