20 rows selected.

You want to export the entire database but want to exclude the SYSTEM and SCOTT only while using the DataPump API.

To perform this operation from the command line for the data pump export (expdp) looks like:


[code]expdp system/passwd directory=DATA_PUMP_DIR dumpfile=EXPDAT%U.DMP FULL=y exclude=schema:\"IN \(\'SCOTT\',\'SYSTEM\')\"

Solution

The equivalent operation using the Data Pump API PL/SQL code to perform the same operation would looks like:

connect system/passwd

declare

h1 number; -- Datapump handle

dir_name varchar2(30); -- Directory Name

begin

dir_name := 'DATA_PUMP_DIR';

h1 := dbms_datapump.open(operation =>'EXPORT',

job_mode =>'FULL',

job_name =>'FULL MINUS SCHEMAS',

version => 'COMPATIBLE');

dbms_datapump.set_parallel(handle => h1, degree => 1);

dbms_datapump.add_file(handle => h1,

filename => 'EXPDAT.LOG',

directory => dir_name,

filetype => 3);

dbms_datapump.set_parameter(handle => h1,

name => 'KEEP_MASTER',

value=> 0);

dbms_datapump.add_file(handle => h1,

filename => 'EXPDAT%U.DMP',

directory => dir_name,

filetype => 1);

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.metadata_filter(handle => h1,

name => 'NAME_EXPR',

value =>'NOT IN(''SCOTT'',''SYSTEM'')',

object_type => 'SCHEMA');

dbms_datapump.set_parameter(handle => h1,

name => 'ESTIMATE',

value =>'BLOCKS');

dbms_datapump.start_job(handle => h1,

skip_current => 0, abort_step =>0);

dbms_datapump.detach(handle => h1);

end;

/

Upon review of the export log file (EXPDAT.LOG), you will be able to see from that the export excluded the SYSTEM and SCOTT schemas from the full export.
