客戶的32位oracle數據庫系統磁盤出現損壞，慶幸的是oracle數據庫完好無損。客戶要求將數據庫遷移到新購的設備上，新設備內存為64G，系統REDHAT 6.2 64位，直接拷貝數據文件肯定是不行的，因為oracle 的存儲過程在32位和64位平台下的wordsize不同，雖然用戶的存儲過程可以在使用時自行完成重新編譯，但oracle的系統存儲過程確需要我們來手工轉換。
總結，遷移過程如下：
1：備份oracle數據庫
2：備份控制文件到trace（以備需要新建控制文件）
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: 查看當前的數據庫狀態
SQL> select count(*) from dba_objects where status ='INVALID'; COUNT(*) ---------- 0 SQL> select comp_name,status from dba_registry; COMP_NAME STATUS ---------------------------------------- ---------------------- Oracle Database Catalog Views VALID Oracle Database Packages and Types VALID Oracle Workspace Manager VALID JServer JAVA Virtual Machine VALID Oracle XDK VALID Oracle Database Java Packages VALID Oracle Expression Filter VALID Oracle Data Mining VALID Oracle Text VALID Oracle XML Database VALID Oracle Rules Manager VALID COMP_NAME STATUS ---------------------------------------- ---------------------- Oracle interMedia VALID OLAP Analytic Workspace VALID Oracle OLAP API VALID OLAP Catalog VALID Spatial VALID Oracle Enterprise Manager VALID 17 rows selected.
4：拷貝參數文件，控制文件，數據文件，日志文件到64位數據庫
5：在64位系統上創建相應目錄，如udmp adump等，要和32位系統一致
6：如果數據庫的數據文件目錄發生變化，則需要新建控制文件，（最好保持源庫和目標庫的一致，減少工作量和錯誤發生率）
7：將數據庫中的存儲過程等置為失效,UTLIRP腳本會將存儲過程等置為失效
<span style="white-space:pre"> </span>--如果遷移的是oracle9i的數據庫，執行如下命令： SQL> STARTUP MIGRATE --如果是Oracle10g或11g，執行如下命令： SQL> STARTUP UPGRADE SQL> SPOOL EASY.log; SQL> @$ORACLE_HOME/rdbms/admin/utlirp.sql SQL> SPOOL OFF;
8: 重新啟動數據庫，
9: 如果數據庫有OLAP組件，則刪除OLAP，以sys用戶執行如下腳本
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 ---只需要在11g中執行。在10g中，catnoamd.sql 腳本中已經包含了該腳本，所以不用執行 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：編譯失效對象
SQL> @?/rdbms/admin/utlrp.sql
此時會有錯誤，這是因為olap沒有安裝，下面安裝olap，然後重新編譯
11：添加OLAP
SQL> @?/olap/admin/olap.sql SYSAUX TEMP;
<pre name="code" class="sql">SQL> @?/rdbms/admin/utlrp.sql --這次會非常快
12. 驗證無效對象和組件狀態
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 ---------------------------------------- ---------------------- Oracle Database Catalog Views VALID Oracle Database Packages and Types VALID Oracle Workspace Manager VALID JServer JAVA Virtual Machine VALID Oracle XDK VALID Oracle Database Java Packages VALID Oracle Expression Filter VALID Oracle Data Mining VALID Oracle Text VALID Oracle XML Database VALID Oracle Rules Manager VALID COMP_NAME STATUS ---------------------------------------- ---------------------- Oracle interMedia VALID OLAP Analytic Workspace VALID Oracle OLAP API VALID OLAP Catalog VALID Spatial VALID Oracle Enterprise Manager VALID
11：重新編譯java對象
