Export schema from tablespace

Hello Everyone,
I work with an enterprise application that uses oracle to store meta data and objects as well as BLOB's in the tablespace.
I have a question about exporting schema's from a table space.
I have Oracle 9.2.0.8 in Windows 2003.
I have a tablespace called TestData02, I created 2 users (orauser1 and orauser2) both with this table space as the default. From within my enterprise application I would use it's tool to initialize the tablespace and create a schema.
What I did was create 2 schema's under one tablespace, one schema owned by 'orauser1' and another by 'orauser2'.
Now I'd like to export everything owned by the user 'orauser2' and create a new tablespace called TestData03 and import this schema and all associated data and BLOBS into here.
I've been reading about the exp and imp tools, but just can't figure out how to export a schema ... I did figure out (i think) how to export the entire table space, but thats not what I want.
Can anyone help me ... I am quite new to oracle.

Hi Pavan,
Before 10g expdp and impdp (this is one of the reasons why versions are really important), any ''dependent' objects will not be 'remapped'.
Let's say you have T1 in TS1, and a primary key in IX_TS1.
Now you move the table to a different user with different tablespaces.
You can 'move' the table, using the default tablespace of the new owner, however, the index will be created in the old tablespace.
This is why you often need to precreate objects.
Without seeing the definition of the LOBsegment, there is no conclusive evidence, but you probably do have a LOBsegment in TS1, which isn't going to be 'remapped'
expdp and impdp will take care of this with the remap_tablespace clause.

Exporting schema from 11.1.0.7 to 10.2.0.4

I am working on Oracle Database version 11.1.0.7 on Solaris 10. I need to export a schema from this version and import into 10.2.0.4 version i Windows 2003.
So should I install 10.2.0.4 client on Solaris and run exp to create a 10.2.0.4 dump file.
Should I run any specific scripts before running 10.2.0.4 exp on 11.1.0.7 database?
IN case of datapump will using version parameter solve the issue like
expdp version=10.2.0.4
Let me know if I'm wrong and any other suggestions are welcome?

I the exp optons will take quite some time as I dont have 10g software installed on the machine and it is 40G export so by network it is going to take a while.
I think datapump verion=10.2.0.4 is something to consider here?
expdp system/..... schemas=hr directory=sample_dir dumpfile=hr.dmp logfile=hr.log version=10.2.0.4
is the previous command correct way of doing it ?
Once done while importing think so I dont need to do anything extra there
impdp system/.... directory=sample1_dir dumpfile=hr.dmp logfile=hr.log
Also should I run any scripts before doing expdp at source or impdp at target?

Export schema from one machine to other machine by datapump

can I export 10g schema from one machine other machine (10g) if how
thanks

In the same manner as You ould use expdp/impdp on the same machine.
expdp needed data on one server.
copy dmp file to another
impdp on another server

Export Schema from 24x7 OLTP

I have been asked to take a full export of a database schema from a 24x7 production instance.
This schema is heavily in use with lots of DML's and Selects, Can I use 'EXP' utility to take an online full export of this schema?
Please answer as it is very urgent. Thanks in advance.

Hello,
Though using datapump is a better choice but it needs to be run on server itself and it will be drain on system resources,so use it with caution. Where conventional exp can be run from client and if your client is connected over same LAN or in same physical location as your production server, you should go great using "exp".
Use "feedback" option to monitor the progress of export. you can also cherry pick options of constraints, indexes, .. to speed up "export" little faster.

Import/export schema with ODI

Hi all,
do you know if with ODI11g I can import a full schema from Oracle database to another Oracle database?
Thanks
Erika

why don't use imp/exp command to export schema from source db and import into target db.
1) export11g ODI repository schemas in DMP files
example : my 11g schemas are "ODI_MASTER" and "ODI_WORK"
exp userid=odi_master/*odi_master* file=c:\odi_master.dmp
exp userid=odi_work/*odi_work* file c:\odi_work.dmp
2) import the dump file into new schemas in the new database (or is it the same database ? in my case, it was a different one)
imp userid=SYSTEM/password touser=odi_master fromuser=odi_master file=c:\odi_master.dmp
imp userid= SYSTEM/password touser=odi_work fromuser=odi_work file=c:\odi_work.dmp

Can one export a schema from a 64 bit Oracle DB into a 32 bit Oracle DB?

Hello:
I need to copy a schema from one DB to another. The source DB runs 64 bit version of Oracle DB but the target DB runs 32 bit version of Oracle DB. Can the schema in 64 bit DB instance be exported and imported into a 32 bit DB instance with exp/imp or expdp/impdp command? Thanks.

Hello:
Thanks for your help. Please see part of the error message below. In the new db, I have created the same user with same password and also grant connect and resource privilege to that user. But I don't understand why some table could be recreated without any issue while all those with BLOB column cannot.

How to export a user and their schema from one 10g database to another?

Hi,
I would like to export a user and their entire schema from one 10g database to another one. How do I do this?
thx
adam

If you want to export a user and the schema owned to the user, and import to the same user in a different database, or a different user in the same database, you can use the exp and imp commands as described in the Utilities manual.
These commands are very versatile and have a lot of options - well worth learning properly. To give you a simplistic shortcut, see below - I create a user 'test_move', create some objects in the schema, export, create a new user in the database 'new_move' and import.

There are many variations on the theme ...
You can simplify this. You can select tables individually. You can use a parameter file. You can transport all the constraints and data. You can skip the data and only move the definitions. You can get some help (imp/exp help=yes).
And, if it's all 10g, there is a new and improved facility called expdp/impdp (dp = data pump) which has a lot more capability as well, including direct transfer (no intermediate file) together with suspend/restart. Also documented in the Utilities manual.

A small schema from 120 GB export could not be imported

Dear,
could you please be so kind and advice me what could be a problem for the following issue?
I have 8.1.7 database on W2K (it is a shame, bit it is not a topic of my question) and I have to import one schema from 120 GB export done successfully few days ago. How to say - very simple task. So, I created the different user (e.g. TARGET_USER) in database, granted connect, resource privileges, and let me go:
cmd> set ORACLE_SID=SID
cmd> imp userid=sys fromuser=SOURCE_USER touser=TARGET_USER file=120_GB_export.dmp log=imp.log
So, import takes some time, I observe in task manager number of data read by IMP.EXE program. When the value reaches about 80 GB at about all tables are imported and then import goes on. When the number of data read from disk (values in task manager) reaches about 95% of export size the process hangs.
Checking in database: a) session is INACTIVE, b) in V$SESSION_WAIT I could find the following event: SQL*NET message from client, SECONDS_IN_WAIT increasing to minutes, hours and does not finish.
Have you any idea?
Kind Regards, Piotr

Try importing just the data first and re-create the indexes later.
Monitor the import process using,
SELECT
SUBSTR(sql_text, INSTR(sql_text,'INTO "'),30) table_name
, rows_processed
, ROUND( (sysdate-TO_DATE(first_load_time,'yyyy-mm-dd hh24:mi:ss'))*24*60,1) minutes
, TRUNC(rows_processed/((sysdate-to_date(first_load_time,'yyyy-mm-dd hh24:mi:ss'))*24*60)) rows_per_minute
FROM
sys.v_$sqlarea
WHERE
sql_text like 'INSERT %INTO "%'
AND command_type = 2
AND open_versions > 0;
check the alert.log for any errors reported.
