Question

用例：客户将在dmp文件中发送其数据库备份。这就是他们发送的一切。

我正在构建一个脚本，该脚本将使用DBMS_DATAPUMP将该dmp文件导入Oracle。但是，因为我不知道原始的表空间名称，所以我收到以下错误： ORA-39083：对象类型USER：＆＃34; XXXXX＆＃34;无法创建错误： ORA-00959：tablespace＆＃39; XXXXXXX＆＃39;不存在

这是我的PL / SQL程序：

    PROCEDURE IMPORTING 
(
  DMPFILES IN VARCHAR2,
  FROMSCHEMA IN VARCHAR2,
  TOSCHEMA IN VARCHAR2
) AS
  ind NUMBER;              -- Loop index
  h1 NUMBER;               -- Data Pump job handle
  percent_done NUMBER;     -- Percentage of job complete
  job_state VARCHAR2(30);  -- To keep track of job state
  le ku$_LogEntry;         -- For WIP and error messages
  js ku$_JobStatus;        -- The job status from get_status
  jd ku$_JobDesc;          -- The job description from get_status
  sts ku$_Status;          -- The status object returned by get_status
  array apex_application_global.vc_arr2;
BEGIN
  h1 := DBMS_DATAPUMP.open('IMPORT','FULL',NULL,'EXAMPLE1'); 
  dbms_datapump.add_file(handle => h1, filename => 'IMPORT.LOG', directory => 'DATA_PUMP_DIR', filetype => 3);
  -- usign this function to split the files passed as a String to an array
  array  := apex_util.string_to_table(DMPFILES, ',');

  for i in 1 .. array.count loop
    DBMS_DATAPUMP.ADD_FILE(h1,array(i),'DATA_PUMP_DIR');
  end loop;

  DBMS_DATAPUMP.METADATA_REMAP(h1,'REMAP_SCHEMA',FROMSCHEMA,TOSCHEMA);

dbms_datapump.set_parameter(handle => h1, name =>
'INCLUDE_METADATA', value => 1);
 dbms_datapump.set_parameter(handle => h1, name =>
'DATA_ACCESS_METHOD', value => 'AUTOMATIC');
 dbms_datapump.set_parameter(handle => h1, name =>
'REUSE_DATAFILES', value => 0);
 dbms_datapump.set_parameter(handle => h1, name =>
'SKIP_UNUSABLE_INDEXES', value => 0);

  DBMS_DATAPUMP.START_JOB(h1);

-- The import job should now be running. In the following loop, the job is 
-- monitored until it completes. In the meantime, progress information is 
-- displayed. Note: this is identical to the export example.

 percent_done := 0;
  job_state := 'UNDEFINED';
  while (job_state != 'COMPLETED') and (job_state != 'STOPPED') loop
    dbms_datapump.get_status(h1,
           dbms_datapump.ku$_status_job_error +
           dbms_datapump.ku$_status_job_status +
           dbms_datapump.ku$_status_wip,-1,job_state,sts);
    js := sts.job_status;

-- If the percentage done changed, display the new value.

     if js.percent_done != percent_done
    then
      dbms_output.put_line('*** Job percent done = ' ||
                           to_char(js.percent_done));
      percent_done := js.percent_done;
    end if;

-- If any work-in-progress (WIP) or Error messages were received for the job,
-- display them.

       if (bitand(sts.mask,dbms_datapump.ku$_status_wip) != 0)
    then
      le := sts.wip;
    else
      if (bitand(sts.mask,dbms_datapump.ku$_status_job_error) != 0)
      then
        le := sts.error;
      else
        le := null;
      end if;
    end if;
    if le is not null
    then
      ind := le.FIRST;
      while ind is not null loop
        dbms_output.put_line(le(ind).LogText);
        ind := le.NEXT(ind);
      end loop;
    end if;
  end loop;

-- Indicate that the job finished and gracefully detach from it. 

  dbms_output.put_line('Job has completed');
  dbms_output.put_line('Final job state = ' || job_state);
  dbms_datapump.detach(h1);
END IMPORTING;

基本上我的问题是：有没有办法在不知道原始表空间的情况下将dmp文件导入Oracle？

提前感谢您的帮助。

更新：我发现在使用这个脚本时，我还需要知道模式名称。这样就会对脚本进行以下更改：

     PROCEDURE IMPORTING 
(
  DMPFILES IN VARCHAR2,
  FROMSCHEMA IN VARCHAR2,
  TOSCHEMA IN VARCHAR2,
  FROMTABLESPACE IN VARCHAR2,
  TOTABLESPACE IN VARCHAR2
) AS
  ind NUMBER;              -- Loop index
  h1 NUMBER;               -- Data Pump job handle
  percent_done NUMBER;     -- Percentage of job complete
  job_state VARCHAR2(30);  -- To keep track of job state
  le ku$_LogEntry;         -- For WIP and error messages
  js ku$_JobStatus;        -- The job status from get_status
  jd ku$_JobDesc;          -- The job description from get_status
  sts ku$_Status;          -- The status object returned by get_status
  array apex_application_global.vc_arr2;
BEGIN
  h1 := DBMS_DATAPUMP.open('IMPORT','FULL',NULL,'EXAMPLE1'); 
  dbms_datapump.add_file(handle => h1, filename => 'IMPORT.LOG', directory => 'DATA_PUMP_DIR', filetype => 3);
  -- usign this function to split the files passed as a String to an array
  array  := apex_util.string_to_table(DMPFILES, ',');

  for i in 1 .. array.count loop
    DBMS_DATAPUMP.ADD_FILE(h1,array(i),'DATA_PUMP_DIR');
  end loop;

  DBMS_DATAPUMP.METADATA_REMAP(h1,'REMAP_TABLESPACE',FROMTABLESPACE,TOTABLESPACE);
  DBMS_DATAPUMP.METADATA_REMAP(h1,'REMAP_SCHEMA',FROMSCHEMA,TOSCHEMA);

dbms_datapump.set_parameter(handle => h1, name =>
'INCLUDE_METADATA', value => 1);
 dbms_datapump.set_parameter(handle => h1, name =>
'DATA_ACCESS_METHOD', value => 'AUTOMATIC');
 dbms_datapump.set_parameter(handle => h1, name =>
'REUSE_DATAFILES', value => 0);
 dbms_datapump.set_parameter(handle => h1, name =>
'SKIP_UNUSABLE_INDEXES', value => 0);

  DBMS_DATAPUMP.START_JOB(h1);

-- The import job should now be running. In the following loop, the job is

 percent_done := 0;
  job_state := 'UNDEFINED';
  while (job_state != 'COMPLETED') and (job_state != 'STOPPED') loop
    dbms_datapump.get_status(h1,
           dbms_datapump.ku$_status_job_error +
           dbms_datapump.ku$_status_job_status +
           dbms_datapump.ku$_status_wip,-1,job_state,sts);
    js := sts.job_status;

-- If the percentage done changed, display the new value.

     if js.percent_done != percent_done
    then
      dbms_output.put_line('*** Job percent done = ' ||
                           to_char(js.percent_done));
      percent_done := js.percent_done;
    end if;

-- If any work-in-progress (WIP) or Error messages were received for the job,
-- display them.

       if (bitand(sts.mask,dbms_datapump.ku$_status_wip) != 0)
    then
      le := sts.wip;
    else
      if (bitand(sts.mask,dbms_datapump.ku$_status_job_error) != 0)
      then
        le := sts.error;
      else
        le := null;
      end if;
    end if;
    if le is not null
    then
      ind := le.FIRST;
      while ind is not null loop
        dbms_output.put_line(le(ind).LogText);
        ind := le.NEXT(ind);
      end loop;
    end if;
  end loop;

-- Indicate that the job finished and gracefully detach from it. 

  dbms_output.put_line('Job has completed');
  dbms_output.put_line('Final job state = ' || job_state);
  dbms_datapump.detach(h1);
END IMPORTING;

我测试了我导出的dmp，所以我知道了TableSpace和Schema名称。

总结：然后可以从dmp文件中知道表空间名称和模式名称吗？

感谢。

简答：没有

答案很长：是如果您生成ddl文件，那么您实际上可以grep fille并搜索表空间和用户。请参阅脚本以生成DDL文件：

create or replace

    end if;

      ind := le.FIRST;
      while ind is not null loop
        dbms_output.put_line(le(ind).LogText);
        ind := le.NEXT(ind);
      end loop;
    end if;
  end loop;

-- Indicate that the job finished and gracefully detach from it. 

  dbms_output.put_line('Job has completed');
  dbms_output.put_line('Final job state = ' || job_state);
  dbms_datapump.detach(h1);
END GENERATE_SQL;
