Export/Import/SQL Loader :: Expdp To Export Multiple Schemas
Aug 2, 2012
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).

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,

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?

DB version : 11.2.0.2 Enterprise Edition
Platform : RHEL 5.6
I have an expdp dump of a schema (HRTB_AP_PROD). I wanted to create 3 schemas from this dump in one go. So i tried this
## The parfile I used
DIRECTORY=DPUMP_DIR
DUMPFILE=HRTB_AP_PROD%u.dmp
LOGFILE=TheThreeSchemas-imp.log
remap_schema=HRTB_AP_PROD:HRTB_AP_DEV1
remap_schema=HRTB_AP_PROD:HRTB_AP_DEV2
remap_schema=HRTB_AP_PROD:HRTB_AP_DEV3
exclude=statistics
parallel=2
nohup impdp '/ as sysdba' parfile=impdp-aug23.par &But i encountered
ORA-39046: Metadata remap REMAP_SCHEMA has already been specified.When I googled it found the following link in which Dean Says , it is not possible.
Re: one dump file inport into multiple schema
So, I had to run 3 separate imports (impdp) to do this.
This is a bit wierd. I am surprized that Oracle guys haven't done anything about this . This is like DB2 !

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?

We are getting the below errors while migrating partitioned tables using expdp.
The source and target databases are both running on 10.2.0.5 and the main thing is source database doesn't have any active sessions. This is a clone of a Prod Database and no one is accessing it.

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
data.dmp CONTENT=all tableexists_action=replace query='tbaadm.ACCOUNT_LIEN_HISTORY_TABLE:"where ACID in(select FINACLE_INT_BNK_ACC

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 3 dump files: A.dmp, B.dmp, C.dmp . Can I use multiple REMAP_TABLESPACE entries in a par file to remap the table spaces for the above dump file?
Parfile would look something like this:
DIRECTORY=dpump
DUMPFILE=A.dmp,B.dmp,C.dmp
JOB_NAME=import_3_schemas
REMAP_TABLESPACE=A1:D1
REMAP_TABLESPACE=B1:E1
REMAP_TABLESPACE=C1:F1
The first remap entry is only relevant to A.dmp file
The second remap entry is only relevant to B.dmp file
etc.

I am using Oracle 10g Data Pump Export utility expdp. What I am trying to do is to export a single schema, except for a certain partition P in table T.
I have tried:
expdp user/pass@db dumpfile=... logfile=... exclude=table:" = 'T:P' "
It doesn't work. The whole table T gets exported.
Is there a way to exclude partitions from schema mode export?
If not, is there a way I can achieve the same with DBMS_DATAPUMP API?

When we set Consistent parameter as yes during export, we get a consistent dump of the database/ schema from the point it was taken by setting the transaction Read only.
So let say we are exporting a table TAB_1 and at the same time a different user updates one of the row of this table and then another user updated this row again so and so forth. So from where do export gets the image of this row which was present at the point in time when the export was initiated in the first place. Is it the Undo?

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.

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 ??
