将oracle从数据库32位平台迁移到64位置
客户32位置oracle数据库系统的磁盘损坏,幸运的是,oracle数据库完美无损。客户数据库迁移到新购设备。新设备的内存64G,制REDHAT 6.2 64位置,直接拷贝数据文件肯定是不。由于oracle 的存储过程在32位和64位平台下的wordsize不同。尽管用户的存储过程能够在使用时自行完毕又一次编译,但oracle的系统存储过程确须要我们来手工转换。
总结,迁移步骤例如以下:
1:备份oracle数据库
2:备份控制文件到trace(以备须要新建控制文件)
SQL> alter database backup controlfile to trace; Database altered. SQL> oradebug setmypid
Statement processed.
SQL> oradebug tracefile_name
/u01/app/admin/easy/udump/easy_ora_18830.trc
SQL> host cat /u01/app/admin/easy/udump/easy_ora_18830.trc

3: 查看当前的数据库状态

4:拷贝參数文件。控制文件,数据文件。日志文件到64位数据库
5:在64位系统上创建对应文件夹,如udmp adump等,要和32位系统一致
6:假设数据库的数据文件文件夹发生变化。则须要新建控制文件,(最好保持源库和目标库的一致。降低工作量和发生错误率)
7:将数据库中的存储过程等置为失效,UTLIRP脚本会将存储过程等置为失效
<span style="white-space:pre"> </span>--假设迁移的是oracle9i的数据库。运行例如以下命令:
SQL> STARTUP MIGRATE --假设是Oracle10g或11g,运行例如以下命令:
SQL> STARTUP UPGRADE SQL> SPOOL EASY.log;
SQL> @$ORACLE_HOME/rdbms/admin/utlirp.sql
SQL> SPOOL OFF;
8: 又一次启动数据库,
9: 假设数据库有OLAP组件,则删除OLAP,以sys用户运行例如以下脚本
SQL> conn / as sysdba ----> Remove OLAP Catalog
SQL> @?/olap/admin/catnoamd.sql ----> Remove OLAP API
SQL> @?/olap/admin/olapidrp.plb
SQL> @?/olap/admin/catnoxoq.sql ----> Deinstall APS - OLAP AW component
SQL> @?/olap/admin/catnoaps.sql
SQL> @? /olap/admin/cwm2drop.sql ---仅仅须要在11g中运行。在10g中。catnoamd.sql 脚本中已经包括了该脚本,所以不用运行 You could getsome invalid objects under SYS and PUBLIC owner, and they are the old duplicate OLAPSYS objects copied under these schemas when Olap has been installedpreviously.
Generally, theOlap objects are named with context like %OLAP%, %AWM%, or other Olap word keys intheir "object_name" field, however, if it needs a help to recognizethem, then please contact Oracle Support and create a Service Request toget assistance for this question. Note that catnoadm.sql could fail from 10.1.0.5 to 11.1.0.7release. Due to the factthat it refers to three scripts which don't get shipped until 11.2 this scriptwill fail.
Besides that itwill error on 7 non-existing synonyms to drop. Prior 11.2, execute these three dropsynonym statements: SQL> drop public synonym OlapFactView;
SQL> drop public synonym OlapDimView;
SQL> drop public synonym DBMS_ODM;
10:编译失效对象
SQL> @?/rdbms/admin/utlrp.sql
此时会有错误,这是由于olap没有安装,以下安装olap,然后又一次编译
11:加入OLAP
SQL> @?/olap/admin/olap.sql SYSAUX TEMP;
<pre name="code" class="sql">SQL> @?/rdbms/admin/utlrp.sql --这次会很快
12. 验证无效对象和组件状态
SQL> l
1* select count(*) from dba_objects where status<>'VALID'
SQL> col comp_name for a40
SQL> select comp_name,status from dba_registry; COMP_NAME STATUS
