Export/Import/SQL Loader :: Import To New Table That Has Additional Fields
Dec 22, 2012
I am trying to migrate a table to a new table that has the field sequence changed and also has a new field added. My main question is if it is possible to have datapump add values to the new field in the target table.For example:
-original table has fields a, b, d, c
-new table has fields b, c, d, a, e
I want to load the new table and also include adding values for field e. In this case, field e is a year field, so it should be loaded with '2012'..Does datapump have the ability to do this? Is reorganizing the fields going to cause me any problems? We are on oracle version 11.2.0.3
But the query of import is still runing even not showing any amount of rows to be imported.
i already make the tablespace in which the table was previosuly before dropping but when i check the sapce of tablespace that is also not consuming one error i got preiviously while performing this task is:
Connected to: Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production With the Partitioning, OLAP and Data Mining options Master table "CDR"."SYS_IMPORT_TABLE_03" successfully loaded/unloaded Starting "CDR"."SYS_IMPORT_TABLE_03": cdr/********@tsiindia directory=TEST_DIR dumpfile=CAT_IN_DATA_042012.DMP tables=CAT_IN_DATA_042012 logfile=impdpCAT_IN_DATA_042012.log
[code]....
i check streams_pool_size it will show zero and then i make it to 48M and after that
SQL> show parameter streams_pool_size; NAME TYPE VALUE ----------- streams_pool_size big integer 48M
we have table with 4 clob fields in it.to load text file of 4GB into the table it is taking around 2 hours. volumetric of that file is 40 Million. we are using direct=Y in sqlldr. but because of this clob fields we didn't got any performance improvement.
Why do export-import require temporary tablespace? Since export-import do behave like DMLs, when does temporary tablespace be needed by datapump utility?

Windows 7 64bit I have schema(scott) export with schema level option and imported with different name as (scott1).At regular period of time i need to import the scott to scott1 without affecting existing records.such as *1. Need to append new created records.* *2. Need to append updated records.*
for the above requirement I did in the following way expdp xxxx/******** schemas=SCOTT directory=dumpdir dumpfile=SCOTT_28-SEP-2012.dmp logfile=exp_SCOTT_28-SEP-2012.log imported in the following way impdp xxxx/******** AS SYSDBA REMAP_SCHEMA=SCOTT:SCOTT1 directory=DUMPDIR dumpfile=SCOTT_28-SEP-2012.dmp logfile=imp_SCOTT2_28-09-2012.log TRANSFORM=SEGMENT_ATTRIBUTES:n TABLE_EXISTS_ACTION=APPEND.
The problem is i couldn'table to append the records to existing tables the log error show such ways.

aix 6.111.2.0.3 I have an expdp dump from prod to be imported to our test database.I have imported it using impdp, but to my surprise the tables were imported but lots of indexes were not created? even If I have used TRANSFORM=SEGMENT_ATTRIBUTES:N just to use the default USERS tablespace. How do I import the indexes separately, skipping the tables and other objects?
I try to transfer data from one database to another one through data pump via SQL Developer (data amount is quite important) exporting several tables. Tables export is doing fine, but I encounter the following error when I import the file (I try data only and data + DDL).
"Exception: ORA-39001: argument value invalid dbms_datapump.get_status(64...= ORA-39001: argument value invalid ORA-39000: .... ORA-31619: ...
The file is in the right place, data pump folder of the new database. User is the same on both base, database version are similar.
When I do the import the of succeeding dump, I drop the existing schema "SQL> drop user username cascade;" and import dump by " impdp system .... ". I would like to import a dump to an existing instance but only data import and will leave the current packages and other metadata untouched and unchanged on the said existing instance.
1. Do i need to drop user before the import if my requirements are the above?
2. If i need to drop user, what should be script.
3. For the import itself, what parameter should i use?
4. What are the necessaries I need to consider before doing the import.
Imagine you have 100 schemas backed up (expdp) in a dumpfile and you want to import just one schema from that dumpfile in a DB. You can specify just that one schema you want using SCHEMAS parameter in the impdp. But things are not straightforward when you want use REMAP_SCHEMA.
Here is my scenario: ===================
I took the expdp dump of schemas A and B in one go. So, dumpfile has objects from both A and B.The dumpfile name is : schemas_AandB.dmpNow , I want to create schema C from A using REMAP_SCHEMA parameter
-- Putting each parameter in a separate line for readability impdp PSTREF/PSTREF_123 DIRECTORY=ADET_EFX_DIR DUMPFILE=schemas_AandB.dmp LOGFILE=CreatingCfromA-Impdp.log REMAP_SCHEMA=A:CEverything goes fine. Schema C is created from Schema A in the dumpfile.
But impdp is trying to create schema B as well because schema B was present in the dumpfile. Since the schema B and its objects are already in the DB , I get the following errors.
ORA-31684: Object type USER:"B" already exists ORA-31684: Object type PROCEDURE:"B"."SP_CLEAREXPIREDSESSIONDATA" already exists ORA-31684: Object type PROCEDURE:"B"."SP_DELETESESSIONDATA" already exists ORA-31684: Object type PROCEDURE:"B"."SP_DELETESTATECONTEXTINFO" already exists
[code]...
Trying to avoid schema B in the dumpfile from being imported by specifying SCHEMASBut I got the following error ORA-39065: unexpected master process exception in MAIN ORA-12801: error signaled in parallel query server PZ99, instance oracth214:HEWRAC1 (1) ORA-01460: unimplemented or unreasonable conversion requestedMaybe REMAP_SCHEMA and SCHEMAS parameters won't work together.
Is there any way to prevent the impdp from importing user B and its objects ?
I have taken expdp dump from 11g database running in Development env.Now i want to import this dump into 10g database running in QA env.
while taking export from 11g database i used this script and backup was sucesssful
expdp system TABLES=sss_exp_test.EXP_SB_HEADER_TMP VERSION=10.2 DIRECTORY=RMSDEV_IMP_DIR DUMPFILE=EXP_SB_HEADER_TMP.dmp LOGFILE=EXP_SB_HEADER_TMP_expdp.log
When i trying to import this dump in 10g getting error.
impdp system TABLES=sss_exp.EXP_SB_HEADER_TMP DIRECTORY=RMS_DATA_PUMP DUMPFILE=EXP_SB_HEADER_TMP.dmp LOGFILE=EXP_SB_HEADER_TMP_impdp.log

Export and import of data in oracle forms...i have created 02 boutons one for export his trigger like this:
eclare alrt number; v_directory varchar2(200) := 'c:ackup'; --- that if the C Drive not the Drive that the windows had installed in it. path varchar2(100):='back_up' ||to_char(sysdate,'dd_mm_yyyy-hh24_mi_ss'); v_exp varchar2(200) := 'exp hamada/hamada2013@orcl file = ' ||v_directory ||'' ||path ||'.dmp'; [code]....
this code is correct he expot not only the data but also the creation of the table ....for exemple i do export and everything is good until now and i find the .dmp in the folder backup .. but when i deleted all data from my app and try to import this .dmp iit show me error it tell me thet the table phone is already created...just export the data of phone not the creation of table and data ???? or how can i import just the data from this .dmp ??
I want to export a table ( using exp or expdp ) from client machine. Dump file should be created to client machine. Is this possible ? How to do this ?
When we are doing impdp , with remap_table=a:b, does it create / import indexes also on the new table b. f indexes get imported / created on table b , what will be their names ? ( different from names of table a indexes?)
we have 2 table same structure one of them is empty and the pther one is contain data the vendor do the insert as select but i found he is wrong due to there duplicated ,now i want to use export and then rename the table and then import but i need with export do a condition
exp user/pass tables=MTR_EPPC_CALLED_DATA file=MTR_EPPC_CALLED_DATA.dmp query="where callstarttime >=to_date('01122012','ddmmyyyy') and callstarttime <=to_date('31122012','ddmmyyyy')"
but it's seem the query take one condition how can i use this above condition in export ???also my friend say there is way to insert with rowid is this possible ??
to export a table aprtition we do table=(T1:P1,T1:P2) but what if I have to export, say 50 partitions do I have to write tables=(T1:P1,T1:P2 .......................................,T1:P50) Or is there a simple way to have it in a single go.
While exporting on 11g xe on windows 32, i got messageORA-31626: job does not existORA-31633: unable to create master table

I have a query regarding importing data in a partitioned table. let me make myself more clear with an example:
I have 1 month table that contains 30 partitions single partition for a single day on one machine say machine A. on another machine say machine B i create the same table with the same script which is on machine A for the same table. i loaded data till 1-15th of a month in Machine A table and rest of 15 -30 Days data into table on machine B at the end i want to import the data on partitioned table on machine B that is from 15th -30th to machine A table. I just want to know whether data is properly imported or not not or i need to specify something
I take export partition wise (15 -30th) 15 partitions dumps and imported into Machine A table. Is it possible that i can import day wise partition from 15th to 30th into a partitioned table which already contains data from 1st -15th partition.
