How to use DBMS_DATAPUMP to write to a dba directory to your local client?

h1 NUMBER;

h1 := dbms_datapump.open(operation => 'EXPORT', job_mode => 'SCHEMA', job_name => 'SCHEMA_IMP_JOB');

dbms_datapump.add_file(handle => h1, filename => 'schema_x.dmp', directory => 'LOCAL_DB_DIR');

dbms_datapump.metadata_filter(handle => h1, name => 'SCHEMA_EXPR', value
