oracle 10g 10.2.0.4 32位升级到64位
32位升到64位有以下几种方法：
1.copy datafile后运行脚本升级
2.rman restore后运行脚本升级
3.通过exp/imp,expdp/impdp的transfer tablespace表空间传输
https://blog.csdn.net/jolly10/article/details/82491614
下面的测试是通过rman restore进行升级的过程。
准备将以前安装的所有32位的oracle服务器都升级到64位。
1.当前环境：
[root@qht115 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.6 (Tikanga)
[oracle@qht115 Disk1]$ uname -a
Linux qht115 2.6.18-238.el5 #1 SMP Sun Dec 19 14:22:44 EST 2010 x86_64 x86_64 x86_64 GNU/Linux
[oracle@qht115 ~]$ sqlplus / as sysdba
SQL*Plus: Release 10.2.0.4.0 - Production on Fri Jul 6 12:22:20 2018

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options操作是redhat 5.6 64位的，数据库是10.2.0.4 32位的，目标是只升级数据库到64位，oracle版本号暂不改变。
2. 获取数据库完整的文件，方法可以是冷备份的一致性copy，或者rman完整恢复。
我是通过rman恢复的一个全备份。
[oracle@qht115 orcl]$ pwd
/u01/oradata/orcl
[oracle@qht115 orcl]$ ls
clt_stats01.dbf CSPSPACE_003.dbf redo01.log sysaux01.dbf
control01.ctl l5mspace01.dbf redo02.log system01.dbf
control02.ctl magspace01.dbf redo03.log temp01.dbf
control03.ctl mtrxspace01.dbf redo04.log undotbs01.dbf
CSPSPACE_001.dbf mtrxspace02.dbf redo05.log users01.dbf
CSPSPACE_002.dbf qhtdata01.dbf redo06.log先备份一下，防止升级出现 问题：
[oracle@qht115 orcl]$ cp /u01/oradata/orcl/* /u01/oradata/orcl_bak将32位的oracle软件改名，接着安装64位的oracle：
[oracle@qht115 u01]$ mv /u01/app /u01/app_32bit
[oracle@qht115 u01]$ echo $ORACLE_HOME
/u01/app/oracle/product/10201
[oracle@qht115 u01]$ mkdir -p /u01/app/oracle/product/10201
3.下载64位的oracle 软件，包括 10.2.0.1的基本包以及10.2.0.4的升级包。

sqlplus或rman时如果出现error while loading shared libraries: libaio.so.1，解决办法：
https://blog.csdn.net/jolly10/article/details/82219603
ORACLE_HOME不改变，继续是/u01/app/oracle/product/10201,安装好后：
[oracle@qht115 u01]$ sqlplus / as sysdba
SQL*Plus: Release 10.2.0.4.0 - Production on Fri Jul 6 05:15:02 2018
Copyright (c) 1982, 2007, Oracle. All Rights Reserved.
Connected to an idle instance.
5.准备spfile，先建立spfile中需要的目录
[oracle@qht115 oracle]$ mkdir -p /u01/app/oracle/admin/orcl/adump
[oracle@qht115 oracle]$ mkdir -p /u01/app/oracle/admin/orcl/bdump
[oracle@qht115 oracle]$ mkdir -p /u01/app/oracle/admin/orcl/cdump
[oracle@qht115 oracle]$ mkdir -p /u01/app/oracle/admin/orcl/udump
[oracle@qht115 oracle]$ mkdir -p /u01/app/oracle/admin/orcl/dpdump
[oracle@qht115 oracle]$ mkdir -p /u01/app/oracle/admin/orcl/archive[oracle@qht115 dbs]$ mkdir -p /u01/app/oracle/admin/orcl/flash_recovery_area从其它库中找一个pfile复制到新库
SQL> create pfile='$ORACLE_HOME/dbs/initorcl.ora' from spfile;
File created.
[oracle@qht106 dbs]$ scp initorcl.ora 172.17.61.115:/u01/app/oracle/product/10201/dbs注销掉pfile.ora的#*.use_indirect_data_buffers=TRUE,这个参数是32位能需要用到的，扩展SGA到超过1.7G的。
并新增加参数 _SYSTEM_TRIG_ENABLED = false，关闭DDL审核触发器。
SQL> startup nomount pfile='/u01/app/oracle/product/10201/dbs/initorcl.ora';
ORACLE instance started.6.建立spfile,通过spfile启动来升级数据库。
SQL> create spfile from pfile;
SQL> shutdown immediate;
SQL> startup upgrade;
7.编译对象
SQL> @?/rdbms/admin/utlirp.sql由于是32bit升级到64bit，这个脚本必须执行，从utlirp.sql的说明有这么一段：
@$ORACLE_HOME/rdbms/admin/catupgrd.sql --这个脚本跨版本必须使用，由于我没有跨版本就可以不执行。
重新启动数据库后用utlrp编译失效对象
SQL> shutdown immediate;
SQL> startup@?/rdbms/admin/utlrp.sql
第一次居然执行失败，执行的过程中被异常中止了，查一下无效对象：
SQL> SELECT COUNT(*) FROM obj$ WHERE status IN (4, 5, 6);
COUNT(*)
----------
553
utlrp.sql执行过程中出现问题，无效的对象太多，通过依次执行下列语句
$ cd /u01/app/oracle/product/102/db_1/olap/admin/
SQL> @?/olap/admin/catnoamd.sql
SQL> @?/olap/admin/catnoaps.sql
SQL> @?/olap/admin/catnoxoq.sql
SQL> @?/olap/admin/olapidrp.plb
SQL>@?/olap/admin/olap.sql SYSAUX TEMP;
然后再次执行
SQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql
再次查询
SQL> SELECT COUNT(*) FROM obj$ WHERE status IN (4, 5, 6);
COUNT(*)
----------
47
SQL> select OWNER#,NAME,TYPE# FROM obj$ WHERE status IN (4, 5, 6);

这47个对象都不是系统文件，大多是recyclebin的文件，可以忽略。
