Export/Import/SQL Loader :: Changing Object Names During Expdp Or Impdp?
Mar 11, 2013
I'm curious to know if expdp or impdp is able to change object names during the process. What I mean by this is... can I export out procedures:
procedure1
procedure2
procedure3
Then import them like this:
test_procedure1
test_procedure2
test_procedure3
I'm not sure the expdp or impdp has that ability, but I could have missed it. I know how to remap a schema, but that only changes the schema name.

I have a process to export a schema using expdp and import using impdp. Everything creates successfully except for a trigger. The trigger gives and error that the table or view does not exist. The account that I use to import the schema is different than the schema user but is a highly privileged account. I notice that the schema in the create or replace trigger line of code is remapped (I am using remapping in the impdp syntax) and the rest of the syntax of the trigger (which is just a sequence trigger for a primary key column) does not have the schema. In order to fix the issue, I have my bash script log into oracle as the schema user after the import of the schema and execute the trigger code. why do I have to do this for trigger code but not for other objects like views that create just fine.

I am using expdp command to export the table by specifying Query parameter. But i am unable to export the table based on the condition.
Ex:EXPDP username/password dumpfile=employee.dmp logfile=emp.log directory=DATADIR_EXP TABLES=EMPLOYEE query=EMPLOYEE:"UPDATED_TIME >= '04-JUN-13' AND UPDATED_TIME >= '05-AUG-13'" Estimate in progress using BLOCKS method...Processing object type TABLE_ EXPORT/ TABLE/ TABLE_ DATATotal estimation using BLOCKS method: 3 GBORA-31693: Table data object "<username>"."EMPLOYEE" failed to load/unload and is being skipped due to error:ORA-00933: SQL command not properly endedMaster table "<username>"."EMPLOYEE" successfully loaded/unloaded...Dump file set for <username>.SYS_EXPORT_TABLE_01 is: E:IMPDPemployee.dmpJob "<username>"."SYS_EXPORT_TABLE_01" completed with 1 error(s) at 12:34:45 Oracle 11g,

I have a question related to Oracle Data Pump.
So, I want to export two schemas from database with condition:
1. I want to export scheme_1 with all metadata objects + data.
2. I want to export scheme_2 with only metadata objects.
Oracle version is Oracle EE 10.2.0.4.0, OS - Microsoft Server 2003R2.
As far as I know I can not use parameter EXCLUDE like:
EXCLUDE =TABLES:" IN ('SCHEMA_NAME.TABLE')"
(-but this parameter will give me no tables at all) or I can not use CONTENT=SCHEMA_NAME.METADATA_ONLY, maybe I can use QUERY=where table in (select tablename where schema is .... - but I have tables with same name in both schemas).

My database size is around 2900 GB in AIX 6.1, database version is 10.2.0.3. Everyday I need to take expdp dump backup of a single table which is only 57 MB in size. It takes around 55 minutes to complete the dump backup.
I have noticed that when backup starts , in first phase it does table scan ( we have 330000 tables) , next purely backup begin. My query is ,
1. how to make first my dump backup?
2. is there any way to skip table scan ?

I am asked to migration from oracle 10.2 to 11.2 on Red hat.In 10g,the db has around 50 users including default users like Scott,xdb etc. 1,Should i skip those users when i import? The schema MAHM05 has the tables, None has directly access privilege this schema.
All the users access by synonym.
2,which schema should i import first?
3,What are things i need to check?

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.

I am using EXPDP to export a schema (Oracle 11g R2), and I need to exclude all the tablespaces that the schema is using. I have seen exluding Oracle objects like functions, tables, packages, indexes...etc. But I have not seen excluding tablespaces.Iis it possible to exclude tablespaces while creating the export dump?

I have imported schemas (impdp) from production database (10gR2, RHEL 64bit). One of the schemas has a db_link. The db_link points to a database that exists on the same server - both in production server and also on the new server where I imported the schemas. When I run a simple query in production using this db_link, it works but when I run the same query on the test server (where I imported the schemas), it gives me following error: ORA-02019: connection description for remote database not found I run this in prod database: Select count(1) from SOME_TABLE@my_link; when I run it in new database, it gives the above ORA error - even if I qualify the table and db_link with the schema owner like this: Select count(1) from the_owner.some_table@the_owner.my_link; NOTE: I am not running these queries as schema owner - I do not know the password. I am able to connect to both databases like this from the command prompt: $ sqlplus user@/password@db1$ sqlplus user@/password@db2 Does this mean that I need to recreate the db_link - perhaps every time I import?

I am using the following command for importing data in to oracle database 11g in linux box.
impdp system/test-123 directory=test_dir dumpfile=test.dmp logfile=test.log full=yes remap_schema=test1:test
Here test_dir = /u01/app/oracle/product/11.2.0/db_1/DATABASE/test/dmp
By default the test.log file is getting created in the above said dir (test_dir) but my requirement is I want to have it in a separate dir.

We are importing data from one DB to other.Schema contains 200 tables and each table contains 1million rows. We are using query option to subset the data using different conditions instead of loading full table data .
We want to subset from different tables. But query option in expdp only taking 1800 characters only. why it is taking upto 1800 characters only. Any restriction imposed on query option.how to increase query clause length?
below is the example of export command.
otispa/********@otisua1 schemas=tbaadm directory=PA_OTIS_DIR dumpfile=tbaadm

I have a dumpfile from a database with hundreds of tablespaces. Do I need to remap all of them on impdp or is there a way to point all tables to a default tablespace? I mean, the source database has 200 tablespaces. The target database just 1.

I've got a schema that I've truncated all tables. I have a full schema export I took awhile back, and I'm wanting to import this into the schema to basically 'reset' it.
First time run, I got the :
ORA-39151: Table "xyz.tablename" exists. All dependent metadata and data will be skipped due to table_exists_action of skip
I've been reading through, and see suggestions to add to the par file:
CONTENT=DATA_ONLY TABLE_EXISTS_ACTION=APPEND
And I've seen others use the option for:
table_exists_action=replace
I basically want to put the data back into the tables, and have the indexes rebuilt.....

Should I be able to use network_link and remap_data together?I am trying to do three things at once:- copy data from one db to an other (prod to test)- change schema- mask sensitive dataI would like to avoid using dump files, import from network link would be nice. My initial testing is suggesting the answer is no.
When I use impdp with the following parameter file, sourcetable.column_to_remap is transferred without modifications, no data remapping is
done.userid=importinguser/XX@orcltables=sourceuser.sourcetabletable_exists_action=REPLACEremap_data=sourceuser.sourcetable.column_to_remap:remappgk.remapfnnetwork_link=source_linkremap_schema=sourceuser:importinguserdirectory=dumpdirlogfile=log_of_imp If i dump the data into file first and then import from file, data remapping is done as expected so I believe my remappkg is correct.
t there is something wrong with my parameter file and network_link&remap_data work together!
Edit: Testing is done with 11.2.0.1.0 at Windows Server 2008 R2
Edit2: More testing: 11.1.0.7@linux - Success!,
Edit3: When writing "Edit2" I thought it worked at 11.2.0.1@linux but I was wrong (source data was already remapped). ==> So the answer is yes, they work together at version 11.1.0.7 and they don't seem to work at 11.2.0.1.

I've been using datapump for a long time now but I have not come across this problem before.
Importing just two tables: Table1 data=100Mb=11 million rows
Table2 data=4.2Gb =19.6 million rows
Table1 ran for approx. 5 hours
Table2 ran for approx. 15 hours
If I run the impdp importing both tables in the same par file the default tablespace of the users the import is running as runs out of space due to ORA-01691: unable to extend lob segment <owner>.SYS_LOG0001175799C00045$$ by 512 in tablespace USERS. I do not understand why it is creating objects in order to import tables into someone elses schema.
The environment is Red Hat LINUX 4.1.2-51 running Oracle 11.2.0.1 of Oracle11gR2. This is a 9 node RAC using ASM.

We have troubles with import of transportable tablespace, when i try to import it with system the import is done currectly, when i try to use another user we receive this message :
impdp bmcese/***** directory=TTS_DIR dumpfile=RMCCO_RMC_ANA_STS_ABB_CO121001.dmp TRANSPORT_DATAFILES=/data/TTS/RMCCO_RMC_ANA_STS_ABB_CO121001.dbf logfile=tts_imp_proc.log
ORA-31626: il job non esiste

ORA-06512: a "SYS.KUPV$FT", line 1020
ORA-00959: tablespace 'RMCCO_RMC_UTZ_PP080531' inesistente
this happens only on development server and it work into test server, so i don't think that the problem is in grants(i controlled that are the same and i have tried with DBA grant too and we received the error).Another strange thing is that tablespace 'RMCCO_RMC_UTZ_PP080531' is not included into the dump that i try to import and it doesn't exist in the database.

i'm writing a job to export data on a weekly basis and archive those data in-case needed to be re-imported in future, its important that we able to import successfully if ever needed.
can impdp perform checks to see if dumps are valid ?how about old imp?if not, will it be safe enough to rely on the export log file? in another word is it safe to assume its all safe if there is no error or warning in the exp log?

I'm going to import a single database using FS to a RAC on ASM both are in same server running oracle 11.2.0.3. So I was wondering if can I use network link mode of impdp without setting up a listener using 10gb Ethernet interface ?
I don’t want to incur the overhead of the tcp network layer because both DB single and Rac are on the same server.

Env: RHEL 5.8 RAC 11.2.0.2
I'm currently moving an IOT from one database to another using expdp/imdp. The IOT is non-partitioned and about 100GB in size containing ~1,1 billion rows.
The dumpfile contains nothing else but the IOT. I'm importing with no special parameters, no pre-created IOT, just ordinary dumpfile import. (impdp username/password dumpfile=impdp:iot.dmp nologfile=y )
During import I got unable to extend TEMP errors from impdp.
ORA-39171: Job is experiencing a resumable wait.
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
ORA-39171: Job is experiencing a resumable wait.
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
I had to add 2 additional files to my Temp tablespace (total 96GB of temp) before the import could finish off.
Is this temp usage to be expected when importing IOT's ?

export a subset of the data only from one database to another. Both on AIX.
Source/testdatabase 11.2.0.3 (non-partitioned tables)
Target productiion database 11.2.0.3 (partioned tables)
Tables same column names but diffrenet index structures and traget one to be partitioned hence only want to import the content Each table on source datbaase hascolumn seq number and only want to extract the last few months of data.
TABLES:table1,table2...
DUMPFILE=dump_dir
CONTENT=data_only
QUERY= table1:"WHERE seq_num >100 "want to use expdp but not sure about how to ensure all tables have the WHERE seq_num >100 condition, if leave table1: out and just have
QUERY= "WHERE seq_num >100 " will this condition be applied to all tables which is what we want.
I'm assuming also can use impdp CONTENT=data_only?

I am trying to import on table which i have the export dump file which i take using expdp previously when i load that table on the same host
by using below command:
expdp scott/tiger@db10g tables=EMP,DEPT directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=expdpEMP_DEPT.log
after that i zip that dump and move it to external usb and now i need that table i copy that table and unzip that that dump
Command i am using to do the import is :
impdp scott/tiger@db10g tables=EMP,DEPT directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=impdpEMP_DEPT.log
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:

2. Created a user in the Target database.
3. Created a public link as sys user in the target database.
