azure云迁移后expdp报错ORA-01110: data file 201: '/home/oradata/powerdes/temp01.dbf'

1，expdp的时候报错：

在idc的oracle服务器上正常导入导出都ok的，但是到了azure云上就出故障了：

[oracle@pldb1 oracle]$ expdp  \‘powerdesk/testcrmfile\‘ directory=DIR_DUMP tables=bis_floor,bis_shop,bis_shop_conn,bis_store,bis_cont dumpfile=zhengyin.qu_bak_$(date +%Y%m%d)_02.dmp

[oracle@pldb1 oracle]$

查看temp01.dbf表空间，是online的，貌似没有坏：

SQL> select name,bytes/1024/1024,status from v$tempfile;


NAME
--------------------------------------------------------------------------------
BYTES/1024/1024 STATUS
--------------- -------
/home/oradata/powerdes/temp01.dbf
         68 ONLINE




SQL>

2，google说起是drop一个temp01.dbf

SQL> alter tablespace tempfile "/home/oradata/powerdes/temp01.dbf" drop;
alter tablespace tempfile "/home/oradata/powerdes/temp01.dbf" drop
                          *
ERROR at line 1:
ORA-00972: identifier is too long




SQL> 


SQL> ALTER TABLESPACE tempfile ‘/home/oradata/powerdes/temp01.dbf‘ drop;
ALTER TABLESPACE tempfile ‘/home/oradata/powerdes/temp01.dbf‘ drop
                          *
ERROR at line 1:
ORA-02142: missing or invalid ALTER TABLESPACE option




SQL> 

删除报错了，无效，google不出来比较有效的解决方案

3，尝试添加新的temp02.dbf，这样试试看。

SQL> 
SQL> 
SQL> alter tablespace temp add tempfile ‘/home/oradata/powerdes/temp02.dbf‘ size 60M reuse;


Tablespace altered.


SQL> 


[oracle@pldb1 oracle]$ expdp  \‘powerdesk/testcrmfile\‘ directory=DIR_DUMP tables=bis_floor,bis_shop,bis_shop_conn,bis_store,bis_cont dumpfile=zhengyin.qu_bak_$(date +%Y%m%d)_02.dmp

[oracle@pldb1 oracle]$ 

添加之后还是报错，所以这种方案没有生效。

4，尝试offline离线temp01.dbf，让expdp走temp02.dbf试试，结果成功了

设置离线状态：

SQL> alter database tempfile ‘/home/oradata/powerdes/temp01.dbf‘ offline;


Database altered.


SQL> 
SQL> select name,bytes/1024/1024,status from v$tempfile;


NAME
--------------------------------------------------------------------------------
BYTES/1024/1024 STATUS
--------------- -------
/home/oradata/powerdes/temp01.dbf
          0 OFFLINE


/home/oradata/powerdes/temp02.dbf
         60 ONLINE




SQL> 

再执行expdp成功导出备份结果集：

[oracle@pldb1 oracle]$ expdp  \‘powerdesk/testcrmfile\‘ directory=DIR_DUMP tables=bis_floor,bis_shop,bis_shop_conn,bis_store,bis_cont dumpfile=zhengyin.qu_bak_$(date +%Y%m%d)_02.dmp

[oracle@pldb1 oracle]$ 

OK，最终导入成功了。
