EXP & IMP only restores to same tablespace(s)

Hi All...
I created new user with new tablespace and import dmp to new user
but the import utility imported same tablepspace (increase old datafile size).
even I dropped new user but the old tablespace (datafile) size not reduced?
Sudhir

Normal behavior.
Using conventional exp/imp the correct method to 'relocate' an user is
- make sure the target user doesn't have unlimited tablespace privilege by revoking it
- make sure the user doesn't have quota on the old tablespace and does have quota on the new tablespace
alter user <target user> default tablespace <new tablespace> quota unlimited on <new tablespace> quota 0 on <old tablespace>
- Now import with indexes=n
- run a second import using the parameter indexfile=<any filename>
- Edit the resulting file, changing all tablespaces
- now run the file in sqlplus
- this should be it
Using expdp and impdp, remap_tablespaces on impdp is sufficient

Exp/imp not going to default tablespace

Hi all..
i m using 8i
and i m taking export of one schema by using these command.
exp TEST/TEST file=TEST.dmp log=TEST.log buffer=10240000
and importing
imp TEST/TEST file=TEST.dmp log=imp_test.log full=y buffer=1024000
i have created seprate tablespace for test user and test user's default tablespace is also test.
but when i m importing test schema its going to other tablespace..
how can i take export of one schema and import into other schema and all objects during import should go into defalut tablespace. ???
can i do it using sys... ???

how can i take export of one schema and import into other schema and all objects during import should go into defalut tablespace.Only way is prior to import CREATE empty objects in desired (new) tablespace; then use IGNORE=Y

Exp/Imp with tablespace autocreate?

Hello dear community,
I've got a question about backup with exp/imp. It's not about RMAN, but nevertheless I hope it's the right board.
Is there a command to tell imp to automatically create a specified tablespace from a dumpfile?
For exp I use:
exp.exe user/pass tablespaces=test file=FILE.DMP
For imp I use:
imp.exe user/pass tablespaces=test file=FILE.DMP
Now, if I drop the tablespace between exp and imp, so imp can't restore it. There I manually have to create the specified tablespace first. It would be nice, if there is a way that imp creates the tablespace if it is not present.
Are there maybe some parameter like "autocreate" and "use datafile=..." and so on?
Thanks for help,
best regards,
Ronny

Transportable Tablespaces is a seperate feature whereby you take a physical
copy of tablespace datafiles and "plug" them into the target database.
That is different from taking a logical export dump.
With export dumps, the only way to get the tablespace created is in a FULL
export and import. The CREATE TABLESPACE commands are written into
the dmp file only when a FULL export is done. At import time, you can choose
to import a specific schema in which case, the CREATE TABLESPACE
commands are not executed by import (they must be precreated). So,
CREATE TABLESPACE is executed only when you do a FULL import as well.
Note that this {obviously} creates the same datafile names (including physical
paths) and sizes as existant in the source database. That may or may not
meet your requirements on occassion (eg different filesystem structure,
different sizes planned in the target database).

Exp/imp of tablespace

hi all
could we use exp/imp of tablespace on same database
say we have list of objects in a tablespace and we want to shrink the tablespace size. ( as there are not many transactions ) then can we take export of this tablespace onyly , drop the tablespace , create a new tablesapce with same name but of less size and import objects back from the export dump file into this tablespace
thanks
kedar

So basically you want to shrink the tablespace but you've got objects scattered around in there and it won't coalesce.
There are several ways to do this, not least the one you've mentioned.
An alternative would be to rebuild the objects into a new (smaller) tablespace. If you haven't got the disk space to accomodate a new tablespace and the existing one then, yes, export/import will do the job.

Tablespace exp imp 11G

I have problem,
I want to imp file.dmp to schemauser
schemauser have tablespace default USERS
then I exp schmeauser from my pc. I named file.dmp
then when
I imp from other pc,
I have prepare for schmeausernew with tablespace default tbspace.
when I imp the data I suprise with my default tablespace tbspace not using.
But my imp it take a place in USERS.
Sow my question is, How to imp automaticly to my default tablespace tbspace ???
I don't want to alter table tablespace when I must one by one and also my index.
Thanks.
for Supporting.

Full database exp/imp between RAC and single database

Hi Experts,
we have a RAC database oracle 10GR2 with 4 node in linux. i try to duplicate rac database into single instance window database.
there are same version both database. during importing, I need to create 4 undo tablespace to keep imp processing.
How to keep one undo tablespace in single instance database?
any experience of exp/imp RAC database into single instance database to share with me?
Thanks

JIm,
I also want to know can we add the exclude=tablespace on the impdp command for full database exp/imp?You can't use exclude=tablespace on exp/imp. It is for datapump expdp/impdp only.
I am very insteresting in your recommadition.
But for a full database impdp, how to exclude a table during full database imp? May I have a example for this case?
I used a expdp for full database exp. but I got a exp error in expdp log as ORA-31679: Table data object "SALE"."TOAD_PLAN_TABLE" has long columns, and longs can not >be loaded/unloaded using a network linkHaving long columns in a table means that it can't be exported/imported over a network link. To exclude this, you can use the exclude expression:
expdp user/password exclude=TABLE:"= 'SALES'" ...
This will exclude all tables named sales. If you have that table in schema scott and then in schema blake, it will exclude both of them. The error that you are getting is not a fatal error, but that table will not be exported/imported.
the final message as
Master table "SYSTEM"."SYS_EXPORT_FULL_01" successfully loaded/unloaded
Dump file set for SYSTEM.SYS_EXPORT_FULL_01 is:
F:\ORACLEBACKUP\SALEFULL091113.DMP
Job "SYSTEM"."SYS_EXPORT_FULL_01" completed with 1 error(s) at 16:50:26Yes, the fact that it did not export one table does not make the job fail, it will continue on exporting all other objects.
. I drop database that gerenated a expdp dump file.
and recreate blank database and then impdp again.
But I got lots of error as
ORA-39151: Table "SYSMAN"."MGMT_ARU_OUI_COMPONENTS" exists. All dependent metadata and data will be skipped due to table_exists_action of skip
ORA-39151: Table "SYSMAN"."MGMT_BUG_ADVISORY" exists. All dependent metadata and data will be skipped due to table_exists_action of skip
......ORA-31684: Object type TYPE_BODY:"SYSMAN"."MGMT_THRESHOLD" already exists
ORA-39111: Dependent object type TRIGGER:"SYSMAN"."SEV_ANNOTATION_INSERT_TR" skipped, base object type VIEW:"SYSMAN"."MGMT_SEVERITY_ANNOTATION" >already exists
and last line as
Job "SYSTEM"."SYS_IMPORT_FULL_01" completed with 2581 error(s) at 11:54:57Yes, even though you think you have an empty database, if you have installed any apps or anything, it may create tables that could exist in your dumpfile. If you know that you want the tables from the dumpfile and not the existing ones in the database, then you can use this on the impdp command:
impdp user/password table_exists_action=replace ...
If a table that is being imported exists, DataPump will detect this, drop the table, then create the table. Then all of the dependent objects will be created. If you don't then the table and all of it's dependent objects will be skipped, (which is the default).
There are 4 options with table_exists_action
replace - I described above
skip - default, means skip the table and dependent objects like indexes, index statistics, table statistics, etc
append - keep the existing table and append the data to it, but skip dependent objects
truncate - truncate the existing table and add the data from the dumpfile, but skip dependent objects.
Hope this helps.

Need help for full db exp-imp

Hi,
My database is having undo segment corruption.I have considered and tried a lot of things to come out of the situation,but didn't get any +ve result. So I have decided to take a full database export,rename the database,create a new database on the same system and import the full database in the new database.Will you plz tell me the steps to do this(full db import)? Plz include a wise syntax for full db exp-imp.
Thanks a lot

If your only identified problem was sudden undo corruption to an online instance and you followed the steps referenced on the Burleson site (switch to manual undo management, create a new undo tablespace, drop the old undo tablespace, and switch back to automatic undo management) and then the very next day encountered undo corruption again, I would recommend two simultaneous courses of action:
1) Get the hardware analyzed, this could be a signal of hard drive or controller problems.
2) Scour metalink for any bug references that may be related (or just go ahead and open an iTar).
If you persist in importing to create the database back on this same system and if you must use the same storage, I would at least try to get the file system or volume that the corruption was on taken offline and recreated.
Just an alternate view of things ... good luck!

Refresh using exp/imp

Hi All,
I need to refresh one of my development database using exp/imp utility,i did refreshing using the copy datafiles but new to this ,i have gone thru this forum and did some search on google too but the part that am not getting is suppose my development db already created with same tablespaces name and size and containes every schema as that of source and has data in it which is refreshed earlier, so do i need to wipe out everything and do it right from scratch(create db,tablespace,users) or just wipe out tables and import with (ignore=Y) .Any feedback would be apperciated.
Thanks

Hi,
 
>> do i need to wipe out everything and do it right from

Well you have choices, and you can do whatever you want,
but there are some “best practices”. I’m assuming that you are copying your
PROD database into DEV (a great practice to have a full-sized production system
the TEST and DEV):
 
- You can restore PROD into TEST using RMAN.
 
- You can use the

Oracle Universal Installer</a> to clone a database.
 
- You can “<a style="color: blue; text-decoration: underline; text-underline: single" href="oracle_tips_db_copy.htm">clone
the whole database</a>”, moving the current datafiles and recreating the
instance
 
- You can export from PROD, truncate the tables in DEV
(after a backup) and import IGNORE=Y. This can be very slow, especially for a
large database. However, there are some

Exp/Imp alternatives for large amounts of data (30GB)

Hi,
I've come into a new role where various test database are to be 'refreshed' each night with cleansed copies of production data. They have been using the Imp/Exp utilities with 10g R2. The export process is ok, but what's killing us is the time it takes to transfer..unzip...and import 32GB .dmp files. I'm looking for suggestions on what we can do to reduce these times. Currently the import takes 4 to 5 hours.
I haven't used datapump, but I've heard it doesn't offer much benefit when it comes to saving time over the old imp/exp utilities. Are 'Transportable Tablespaces' the next logical solution? I've been reading up on them and could start prototyping/testing the process next week. What else is in Oracle's toolbox I should be considering?
Thanks
brian

Hi,
I haven't used datapump, but I've heard it doesn't offer much benefit when it comes to saving time over the old imp/exp utilitiesDatapump will be faster for a couple of reasons. It uses direct path to unload the data. DataPump also supports parallel processes, so while one process is exporting metadata, the other processes can be exporting the data. In 11, you can also compress the dumpfiles as you are exporting. (Both data and metadata compression is available in 11, I think metadata compression is available in 10.2). This will remove your zip step.
As far as transportable tablespace, yes, this is an option. There are some requirements, but if it works for you, all you will be exporting will be the metadata and no data. The data is copied from the source to the target by way of datafiles. One of the biggest requirements is that the tablespaces need to be read only while the export job is running. This is true for both exp/imp and expdp/impdp.

Exp/Imp In Oracle 10g client

Hi All,
I want to take one schema export from Oracle 10g Client. I am in new Oracle 10g.
In oracle 9i, we can using exp/imp command for Export and Import from Client itself.
I heard about in Oracle 10g, we can use Expdb/Impdb in Server only. Is there any possibility to take exp/imp in Client also.
Pls help me...
Cheers,

To add up to expdb from oracle client
NETWORK_LINK
Default: none
Purpose
Enables an export from a (source) database identified by a valid database link. The data from the source database instance is written to a dump file set on the connected database instance.
Syntax and Description
NETWORK_LINK=source_database_link
The NETWORK_LINK parameter initiates an export using a database link. This means that the system to which the expdp client is connected contacts the source database referenced by the source_database_link, retrieves data from it, and writes the data to a dump file set back on the connected system.
The source_database_link provided must be the name of a database link to an available database. If the database on that instance does not already have a database link, you or your DBA must create one. For more information about the CREATE DATABASE LINK statement, see Oracle Database SQL Reference.
If the source database is read-only, then the user on the source database must have a locally managed tablespace assigned as the default temporary tablespace. Otherwise, the job will fail. For further details about this, see the information about creating locally managed temporary tablespaces in the Oracle Database Administrator's Guide.
Restrictions
When the NETWORK_LINK parameter is used in conjunction with the TABLES parameter, only whole tables can be exported (not partitions of tables).
The only types of database links supported by Data Pump Export are: public, fixed-user, and connected-user. Current-user database links are not supported.
Example
The following is an example of using the NETWORK_LINK parameter. The source_database_link would be replaced with the name of a valid database link that must already exist.
expdp hr/hr DIRECTORY=dpump_dir1 NETWORK_LINK=source_database_linkDUMPFILE=network_export.dmp LOGFILE=network_export.log

Exp/Import database schema vs Ch 10 Exp/Imp Content

Hi I'm using Portal 10.1.2.02. I'm a DBA tasked with migrating a Dev portal into Test, then Production.
There seems to be a number of ways to achieve this and I was hoping to clarify which is best for me.
I've run through note: 330391.1(copying the Portal schema) which details running a perl script to export and import onto a newly installed server. This process worked will.
Chapter 10 of the Portal guide details a fairly complex process of creating transports sets and migrating these over and importing.
My question is: if I want the entire Portal copied is there any difference in these processes? ie. Do you end up with the same result?
thanks in advance of any advice :-)

The cloning model is not a rerunnable model, its not granular and conditional migraton is not possible.
You can do the cloning only if u want to take a copy of the entire setup and rewire to a new midtier.
Portal exp/imp model helps u to achieve granular, conditional and rerunnable method of moving portal objects.
Apart from that, it comes with the readily available prechecks to intimate what's going wrong during the process.

Migrate oracle 9207 DB 8 TB size frm Solaris to AIX?dont want Exp/Imp

Hi Guys,PLz help
I want migrate 8TB oracle database from Solaris 8 to AIX 5.
In my last post on the same topic I was told to refer Metalink notes
291024.1,Note:77523.1,Note:277650.1
acc to these notes 'EXPORT/IMPORT IS THE ONLY OPTION TO MIGRATE FROM SOLARIS TO AIX'.
I was not convinced as In http://dba.ipbhost.com/index.php?showtopic=9523
I read
"As both solaris and AIX are UNIX O/S, cloning the DB is also possible from source box to target box"
Also
whats the role of "If the endianness is the same"??????
Can you guys plz comment on this again.....as I'm really confused because exp/imp of 8TB
is going to take half of my life :)
PLz tell in any other option in 9.2.0.7?If we have
Thanx

You can do
SELECT PLATFORM_NAME, ENDIAN_FORMAT
FROM V$TRANSPORTABLE_PLATFORMto check endianness of different platform.
-- Note, the view is only on 10g and above.
datafiles from different endian format can't be directly copied over and use. On 10g you have option to use RMAN convert endianness.
with that said, since Solaris and AIX are all big engianness. That means you can directly copy datafiles over and clone database without using exp/imp.
this article has a list of how to clone

Exp/imp problems

Hi,
Kindly Help.
I plan to export full the database then I'll import it back to the same database, my purpose is to fix the fragmentation of the tables/tablespaces.
1. Before importing the export file should I do anything to the database( e.g. truncate the tables, delete the contents)?
2. Does the exp/imp utility depend on the SGA for it's performance or if not the SGA what parameter should I change to speep up the exp/imp?
Thank you

I plan to export full the database then I'll import
it back to the same database, my purpose is to fix
the fragmentation of the tables/tablespaces. Why you using export/import to de-fragmentation, there are other ways to do same like rebuild indexes, Use LMT etc

EXP/IMP with NCLOB/BLOB

Hello all,
I have to pass an schema from one database, to another recreated as the first one (same schema name, same rights, same tablespace, same all) Both are Oracle database 11.2.0.2 enterprise 64 bits on linux 64. Is there any consideration I have to take, as there's objects with NCLOB and BLOB types... I've tryed the export, and it has gone ok without any problem, buy there will be any issue when I import it on the second database?
All this is to change the database's server from the phisical one that it's now, to a virtual one (OVM).
Thanks for your help!!

It would probably be better if you used Data Pump (expdp/impdp) instead of original exp/imp. It has support for more objects and features that you may have used.

Why can't I restore the same version IOS that's on my phone?

My iPhone 4s has apps on it that are not iOS 6x or even 7x compatible. iTunes/Apple won't let me restore the same version of iOS 5 that is currently on my phone that won't boot up. I have no options anymore except to pay.
1. I can pay a developer to migrate the app I use for work to iOS7 and eventually run into the same problem later and pay AGAIN.
2. I can ditch Apple (because there is no logical reason for this) and pay to go over to a Google phone and pay to migrate my app over to android but have the peace of mind that I won't be forced to do what android wants me to do anymore.
I bought an iPhone, an iPhone 3G, an iPhone 3GS and an iPhone 4S. I don't like using the latest and greatest because I only really care about doing what *I* want to do with *MY* phone. I don't like being told I can't have what I've been using for the past 2 years because Apple has changed a policy or something.
Is Apple doing ANYTHING for people like me or are we just screwed? Can anyone explain why Apple would disallow reinstallation of an iOS i've been using for years now?

if you're saying the default function of 'restore' has always been update to latest for your device you'd all be correct.. but that's not what i'm talking about. shift+click restore and you'll be prompted to browse for your firmware. since the dawn of the iphone (ask anyone that's actually used this feature) you have always been able to use this feature to install same-version ios as to what version is on the device. in the past it was more open, allowing you to update to any version above the one you're on, but that was taken away back in IOS3.. for example.
i'm sure for the average user who has no idea what version ios they use or want this would be completely transparent so i don't really blame you for not knowing or using this feature. for others like me this is a big deal. hopefully someone else who is on the same page as i am will chime in..
i think it's a little crazy to force your users to only use the specific version ios you want them to. have you tried ios7 on an ipad2? hello lag. there are more reasons than mine to want to be able to control what software runs on YOUR hardware.. think about it.

EXP & IMP only restores to same tablespace(s)
