ORA-31633: unable to create master table.
SELECT owner_name, job_name, operation, job_mode, state, attached_sessions
You can see the master table.
SELECT o.status, o.object_id, o.object_type, o.owner||'.'||object_name "OWNER.OBJECT"
FROM dba_objects o, dba_datapump_jobs j WHERE o.owner=j.owner_name
AND o.object_name=j.job_name AND j.job_name NOT LIKE 'BIN$%' ORDER BY 4,2;
You can check the running Job:
drop table SYS.EXPDP_JOB;

Create or change a directory for the expdp
CREATE OR REPLACE DIRECTORY DATA_PUMP_DIR AS '/fast_recovery_area/${ORACLE_SID}/dpump';

At the end you may need to execute following command

degree => 8, cascade => true);
SQL> alter system flush shared_pool;
export import NO DATA just Schema Structure.

dumpfile=kardbtes_description_$YYYYMMDD.dmp \ logfile=kardbtes_description_$YYYYMMDD.log
date
Import Schema as follow.
You may need to create table and index before you import
Example:
Tablespace:
CREATE TABLESPACE DATA
DATAFILE '+DATA01' SIZE 1G AUTOEXTEND ON NEXT 1G MAXSIZE UNLIMITED
LOGGING
DEFAULT
NO INMEMORY
ONLINE
EXTENT MANAGEMENT LOCAL AUTOALLOCATE
BLOCKSIZE 16K
SEGMENT SPACE MANAGEMENT AUTO
FLASHBACK ON;
Index
CREATE TABLESPACE INDX
DATAFILE '+DATA01' SIZE 1G AUTOEXTEND ON NEXT 1G MAXSIZE UNLIMITED
LOGGING
DEFAULT
NO INMEMORY
ONLINE
EXTENT MANAGEMENT LOCAL AUTOALLOCATE
BLOCKSIZE 16K
SEGMENT SPACE MANAGEMENT AUTO
FLASHBACK ON;
#!/bin/bash
. /users/oracle/set_home_env KARDBTES
echo $ORACLE_SID
