Oracle Data Pump Export script help

Question

Hi, I'm trying to do a data pump export for metadata on a tablespace (COURSE). Am I on the right track? My data pump directory was created as:

CREATE DIRECTORY dpump_dir AS '/mydata/data';

Please keep in mind that I'm a beginner. This may or may not be the best way to go about this, but I'd like to try to get this working. Thanks very much.

declare
      dp_handle       number;
  begin
      dp_handle := dbms_datapump.open(
      operation   => 'EXPORT',
      job_mode    => 'TABLESPACE');

    dbms_datapump.add_file(
      handle    =>  dp_handle,
      filename  => 'courses.dmp',
      directory => 'dpump_dir');

    dbms_datapump.add_file(
      handle    => dp_handle,
      filename  => 'courses.log',
      directory => 'dpump_dir',
      filetype  => DBMS_DATAPUMP.KU$_FILE_TYPE_LOG_FILE);

    dbms_datapump.metadata_filter(      
      handle => dp_handle,
      name   => 'TABLESPACE_EXPR',
      value  => '''COURSE''');

    dbms_datapump.start_job(dp_handle);

    dbms_datapump.detach(dp_handle);
  end;
  /

Answer 1

Try this:

dbms_datapump.metadata_filter(      
      handle => dp_handle,
      name   => 'TABLESPACE_EXPR',
      value  => '=''COURSE''');

"I still get the same error messages though"

Hmmm.... Remote debugging of other people's code is one of the least fun aspects of SO. Anyway, let's give it another guess.

Do you have an OS directory called /mydata/data which Oracle has read and write privileges on? The CREATE DIRECTORY statement only creates a pointer, it doesn't create the underlying OS directory.

Answer 2

It appears your error is occurring on the first ADDFILE call.

Try making your directory references upper case: directory => 'DPUMP_DIR'
