Estimate size for export file.
==============================
See detailed Explanation Here:
ESTIMATE=BLOCKS
ESTIMATE_ONLY
A parameter that tells expdp process to skip actual export, and only to estimate the size.
Values: Y/N
Default=N
ESTIMATE
Method to estimate the size of a segment.
Values: BLOCKS/STATISTICS
Default: BLOCKS. Number of segment blocks * block size.
The output:

Troubleshooting
==============================
Running expdp.
Where is the generated dmp file?
The output says that there are no errors, and that log file and dmp file were generated.
However when checking the file system, there are no such files.
Permissions are OK, both on Oracle and on UNIX.
Permissions are OK, both on Oracle and on UNIX.
No issue with disk space.
What is going on? Why has the file disappeared.??!!
The issue is, that expdb was run on a client, but dmp files are generated on server side.
In Linux cluster environments, this might be quite confusing...
Running impdp.
OS user running the impdp command has full permissions on the file
What might be wrong?

Additional information: 3
First of all - ORA-39001, ORA-39000,ORA-31640 are general wrapper errors.
The real error is ORA-27037
Stuff to check:
1. userA would need to have permission IMP_FULL_DATABASE permission.
To check on existing permissions:
SELECT user, table_name, privilege
FROM USER_TAB_PRIVS
WHERE privilege IN ('WRITE', 'READ') ORDER BY 1,2
GRANT WRITE ON DIRECTORY EXP_DIR TO my_user
2. Consider cluster environment mount.
In a cluster environment, use CLUSTER=NO to force the job use only the instance where it has been started.
This might be needed because the EXP_DIR directory might be mounted only on the active node, i.e. on a local directory.

==============================
PARALLEL
==============================
To use PARALLEL:
1. check the number of CPUs
less /proc/cpuinfo | grep processor
2. Per Oracle Documantation: "Set the degree of parallelism to two times the number of CPUs, then tune from there"
When using the substitution variable %U, during execution Data Pump Export will determine the optimal degree of parallelism for the export job and create enough dump files for the parallel export processes. Therefore the parameter PARALLEL should be seen as an upper limit value, rather than the actual value for the number of parallel processes.
When using parallel=N - N files would be generated
When importing, simply use the file name template
expdp my_user/my_pass@orainst directory=MY_EXP_DIR parallel=4 dumpfile=EXP_TEMPLATE_%U_${RUN_DATE}.dmp logfile=exp.logRUN_DATE=`date +"%Y%m%d"
RUN_DATE=`date +"%Y%m%d"

Instead, use exp and imp commands
Example:
To Export
exp old_user/old_pass@orainst FILE=exp_old_user.dmp LOG=exp_log.log COMRESS=N
To Import:
imp system/syspass@orainst FILE=exp_old_user.dmp LOG=imp_log.log FROMUSER=old_user TOUSER=new_user STATISTICS=RECALCULATE

Error:

Solution:

In case table has data - imp fill fail with PK violation
There is no way to workaround that!
The solution is to manually truncate tables about to be imported.

Sample Errors
==============================
UDI-00014: invalid value for parameter, 'attach'
impdp MY_USER/MY_PASS@orainst DUMPFILE=Exp_schema.dmp LOGFILE=imp_schema.log DIRECTORY-IG_EXP_DIR
The issue:
There is a "-" instead of "="
Should be:
impdp MY_USER/MY_PASS@orainst DUMPFILE=Exp_schema.dmp LOGFILE=imp_schema.log DIRECTORY=IG_EXP_DIR
==============================
Example: Migrate USER_A from server_a to server_b minus few tables
==============================
The issue: task to migrate user from server to server but without some large tables.
Step A - create user on server B
CREATE USER user_a IDENTIFIED BY user_a DEFAULT TABLESPACE IGT_TABLE PROFILE DEFAULT ACCOUNT UNLOCK;GRANT CONNECT, RESOURCE TO user_a;
GRANT CREATE PROCEDURE, EXECUTE ANY PROCEDURE TO user_a;
GRANT CREATE SNAPSHOT, CREATE TRIGGER, CREATE ANY INDEX TO user_a;
GRANT CREATE SYNONYM TO user_a;
GRANT UNLIMITED TABLESPACE TO user_a;
GRANT QUERY REWRITE TO user_a;
GRANT CREATE ANY DIRECTORY TO user_a;
GRANT EXECUTE ON DBMS_LOCK TO user_a;
GRANT SELECT_CATALOG_ROLE TO user_a;
GRANT CHANGE NOTIFICATION TO user_a;
Step B - export metadata only
exp_metadata.sh:expdp USER_A/USER_A@igt parfile=exp_metadata.prm
exp_metadata.prm:
DIRECTORY=DP_DIR
DUMPFILE=exp_metadata.dmp
LOGFILE=exp_metadata.log
CONTENT=metadata_only
SCHEMAS=user_a
Step C - export data only
exp_data_only.sh:DIRECTORY=DP_DIR
DUMPFILE=exp_data_only.dmp
LOGFILE=exp_data_only.log
CONTENT=data_only
SCHEMAS=USER_A
EXCLUDE=TABLE:"IN ('TABLE_A','TABLE_B','TABLE_B')"
Step D - import metadata only
imp_metadata.sh:impdp system/Xen86Pga@igt parfile=imp_metadata.prm
imp_metadata.prm:
DIRECTORY=DP_DIR
DUMPFILE=exp_metadata.dmp
LOGFILE=imp_metadata.log
CONTENT=metadata_only
SCHEMAS=USER_A
Step D - import data only
TABLE_EXISTS_ACTION=TRUNCATE

==============================
GRANT BECOME USER
==============================
In Oracle 12 there is change in permissions of IMP_FULL_DATABASE.
GRANT BECOME USER is revoked from IMP_FULL_DATABASE system privilege.
It is needed during impdp to import objects in the schemas of other users.
To fix this issue:
GRANT BECOME USER TO IMP_FULL_DATABASE;
Without this Grant, this is the error:
Starting "SYSTEM"."SYS_IMPORT_FULL_01": system/********@igt directory=IG_EXP_DIR dumpfile=Exp_databse.dmp logfile=Imp_database.log_20200514_171126 remap_schema=USER_A:USER_B content=METADATA_ONLY
Processing object type SCHEMA_EXPORT/USER
ORA-39083: Object type USER failed to create with error:
ORA-31625: Schema SYSTEM is needed to import this object,
but is unaccessible
ORA-01031: insufficient privileges
==============================
RAC considerations. impdp
==============================
There are some dedicated parameters for datapump in RAC
===========
CLUSTER
===========
impdp on RAC can run in 2 modes:
Option A - Have a directory which is common for both RAC nodes, and run impdp on both nodes in parallel.
Option B - Run the impdp form a directory which is accessible only by one node.
CLUSTER values
CLUSTER=N This will cause impdp worker process to run only on current node.
It is the mode for pre Oracle 11.2 versions.
CLUSTER=Y This will cause impdp worker process to run only on all RAC nodes.
Y is the default value
===========
SERVICE_NAME
===========
SERVICE_NAME should be used together with CLUSTER=Y
Use SERVICE_NAME specify a specific, existing service and constrain worker processes to run only on instances defined for that service.
The SERVICE_NAME parameter is ignored if CLUSTER=N is also specified.
Performance issues:
Use of the CLUSTER parameter may affect performance because there is some additional overhead in distributing the import job across Oracle RAC instances.
For small jobs, it may be better to specify CLUSTER=N to constrain the job to run on the instance where it is started.
For jobs involving large amounts of data, better to use the CLUSTER parameter.
===========
PARALLEL
===========
Up to 3 parallel processes can be used.
Example:
impdp hr/hr@orainst DIRECTORY=DPUMP_DIR DUMPFILE=hr.dmp LOGFILE=dpump_hr_log CLUSTER=N PARALLEL=2
==============================
Code Example: Script to exclude big tables from expdp

Some unexpected tables exist under application user schema:

SYS_EXPORT_SCHEMA_02
SYS_EXPORT_SCHEMA_03
etc
COL owner_name FOR A30
COL job_name FOR A30
COL operation FOR A10
COL job_mode FOR A10
COL state FOR A20
COL state FOR A20
SET LINESIZE 140
SELECT owner_name, job_name, operation, job_mode, state, attached_sessions
FROM DBA_DATAPUMP_JOBS
ORDER BY job_name;

0
VR2_GROUP_SHARE SYS_EXPORT_SCHEMA_73 EXPORT SCHEMA NOT RUNNING
0
VR2_GROUP_SHARE_V80 SYS_EXPORT_SCHEMA_73 EXPORT SCHEMA NOT RUNNING
0
VR2_GROUP_SHARE SYS_EXPORT_SCHEMA_74 EXPORT SCHEMA NOT RUNNING
0
And the tables in question are the job_name.
Generate DROP TABLE statement, and execute them
Generate DROP TABLE statement, and execute them
SELECT 'DROP TABLE '||owner_name||'.'||job_name||';'
FROM DBA_DATAPUMP_JOBS
WHERE state = 'NOT RUNNING';
-- AND owner_name = 'LAB_QANFV_ALLQQ';
Execute the generated SQLs
To cleanup Recycle bin, run
PURGE DBA_RECYCLEBIN;
