源数据库置于readonly状态
1 SQL> conn sys/oracle_4U@windb as sysdba 2 已连接到空闲例程。 3 SQL> startup mount 4 ORACLE 例程已经启动。 5 6 Total System Global Area 1728053248 bytes 7 Fixed Size 3046512 bytes 8 Variable Size 1023411088 bytes 9 Database Buffers 687865856 bytes 10 Redo Buffers 13729792 bytes 11 数据库装载完毕。 12 SQL> alter database open read only; 13 14 数据库已更改。
确定ENDIAN序列

使用RMAN工具进行CONVERT DATABASE

文件迁移及处理
编辑参数文件（initorcl2）及创建控制文件脚本（createctl.sql）
db_recovery_file_dest = ‘/u01/app/oracle/fast_recovery_area‘ db_recovery_file_dest_size= 6731857920 audit_file_dest = ‘/u01/app/oracle/admin/orcl2/adump‘ db_name = ‘windb‘ memory_target = 2G undo_tablespace = ‘UNDOTBS1‘ control_files =‘/u01/app/oracle/oradata/orcl2/control01.ctl‘,‘/u01/app/oracle/oradata/orcl2/control02.ctl‘,‘/u01/app/oracle/oradata/orcl2/control03.ctl‘ processes = 300 db_block_size = 8192 compatible = ‘12.1.0.2.0‘ open_cursors = 300

启动实例到nomount状态
1 SQL> startup nomount 2 ORACLE instance started. 3 4 Total System Global Area 2147483648 bytes 5 Fixed Size 2926472 bytes 6 Variable Size 1358956664 bytes 7 Database Buffers 771751936 bytes 8 Redo Buffers 13848576 bytes
使用创建控制文件脚本创建控制文件，控制文件创建成功后，实例进入到mount状态
1 SQL> @/u01/app/oracle/oradata/orcl2/createctl.sql
开启数据库
1 SQL> alter database open resetlogs
重新编译数据库对象
1 SQL> shutdown immediate 2 SQL> startup upgrade 3 SQL> @@ ?/rdbms/admin/utlirp.sql 4 SQL> shutdown immediate 5 SQL> startup 6 SQL> @@ ?/rdbms/admin/utlrp.sql
