将ORACLE 10g 32bit数据库还原到测试机ORACLE 10g 64bit的数据库实例上， 还原、恢复数据库后，使用open resetlogs打开数据库后，发现警告日志里面有ORA-12012以及ORA-06553错误：

出现这个错误，是因为32bit和64bit数据库的wordsize不同，需要执行以下步骤完成wordsize的转换。具体可以参考How to Convert a 32-bit Database to 64-bit Database on Linux? (文档 ID 341880.1)

在执行脚本时，会报下面错误，官方解释为Note:If you are changing wordsize for Oracle release10.1.x/10.2.x/11.1/11.2 32-Bit to 64-bit with OLAP enabled for DB then you may likely to see the error
