Exclude tables list kink option in exp/imp ????

Hi,
Is there any option to exclude tables while exp/imp, if so from which version?
Thanks.

Actually, in 10.1 and later, the Data Pump versions of export and import allow you to specify an EXClUDE parameter to exclude one or more tables.

How to exp/imp both diff character set tables between in DB1 and DB2?

In the Solaris 2.7 ,the oracle 8i DB1 has NLS_CHARACTERSET
ZHS16CGB231280 and NLS_NCHAR_CHARACTERSET ZHS16CGB231280
character set.
In other linux7.2 system ,the oracle 8i DB2 is install into the
NLS_NCHAR_CHARACTERSET US7ASCII and NLS_CHARACTERSET US7ASCII
character set.
The tables contents of DB1 have some chinese. I want to exp/imp
tables of DB1 into DB2 . But the chinese can't correct display
in the SQLWheet tools. How do the Exp/Imp operation ? ples help
me . thanks .

The supported way to store GB231280-encoded characters is using a ZHS16CGB231280 database or a database created using a superset of GB231280 ,such as UTF8 .Can you not upgrade your target database from US7ASCII to ZHS16CGB231280 ?
With US7ASCII and NLS_LANG set to US7ASCII , you are using the garbage in garbage out (GIGO) approach. This may seem to work but there are many hidden problems :-
1. Invalid SQL String Function behaviours - LENGTH ( ) , SUBSTR ( ) , INSTR ( )
2. Data can be corrupted when data is loaded into another database. e.g. EXP / IMP , Dblinks
3. Communication with other clients will generate incorrect results. e.g. other Oracle products - Oracle Text, Forms. , Java , HTML etc.
4. Linguistic sorts not available
5. Query using the standard WHERE clause may return incorrect results ..
6. Extra coding overhead in handling character conversions manually.
I recommend you to check out the FAQ and the DB Character set migration guide on the Globalization Support forum on OTN.

Using import (imp) you can list the content of your packages, procedures, functions, views, etc. and perhaps that will give you what you need.
Another choice would be to useSELECT * FROM user_source ORDER BY 2, 1, 3;to list the code.

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.

Migrating from 9i to 10g through exp/imp

Hi,
We need to migrate a database on 9i in HP-UNIX to 10g in IBM AIX. Can you please tell me whether i can export data in 9i with 9i export utility and import it into 10g using 10g data pump utility for faster import ?
We don't have the 10g software installed in the HP-UNIX platform.
And what other alternatives we have to reduce the amount of time for the migration process as it's a critical Production database ?
Thanks,
Jayanta

I believe that Justin is correct that if you use exp to unload the data you will need to use imp and not impdp to reload the data.
To speed up the cross-platform exp/imp process I suggest you consider running multiple concurrent exp/imp jobs. You can generate a table=list into a spool file using sql. You can give each large table its own exp job and bunch the small tables.
Depending on how your database objects are organized you might also be albe to export by owner or a combination of owner, tables= exports.
You can use a full=y with the rows=n option to grab the public synonyms, non-owning users, packages, etc.... not brought in by the prior exp/imp.

Exp/imp data pump

I exported tables in 10g using exp(normal export)command
Can I user impdp(datapump) while doing import

There is no exclude or include option in the traditional export/import (exp/imp) utility. This is only given in datapump (expdp/impdp) to exclude or include the database objects while exporting or importing.
All you can do as work around is, create the structure of the table in the target database/schema, then do import, while import if the table is found in the target schema, then that table will not imported. So, don’t use ignore=y, if you use, even if the table is found during the import, the rows will be imported in fact. Hope you got what I mean.

How to exclude tables while doing import in Traditional import/export

Hi OTN,
Please suggest me, while using Oracle Datapump we can exclude tables as below i mentioned.... if i will use Traditional export/import how can i exclude tables.
impdp tech_test10/[email protected] directory=EAMS04_DP_DIR dumpfile=EXP_DEV6_05092012.dmp logfile=IMP_TECH_TEST10_29MAY.log REMAP_SCHEMA=DEV6:TECH_TEST10 remap_tablespace=DEV6_DATA ATA_TECH_TEST10 remap_tablespace=DEV6_INDX:INDEX_TECH_TEST10 EXCLUDE=TABLE:\"IN $\'R5WSMESSAGES_ARCHIVE\',\'R5WSMESSAGES\',\'R5AUDVALUES\'$\"
Your suggestions will be helpful to me find the way.

you cannot exclude. But you can use tables parameter to list all the tables needs to be exported.
exp scott/tiger file=emp.dmp tables=(emp,dept)
similarly for import

Excluding table in impdp

Hi Friends,
I need to exclude two tables in impdp.. help me in this...
impdp system directory=exportdump tables=SYNC.cin_document query=SYNC.CIN_DOCUMENT:'"where rownum<10"' dumpfile=satexpdpdump.dmp logfile=1.log CONTENT=DATA_ONLY EXCLUDE=TABLE:"SYNC.CIN_DETAIL,SYNC.CIN_DOCUMENT_GTIN"

ORA-39071: Value for EXCLUDE is badly formed.
ORA-00920: invalid relational operator

Thanks friends ,,, I got the solution.
Solution:
instead of excluding i have mentioned only one table name in "tables=SYNC.cin_document" field. I have just removed the EXCLUDE option ..It is working fine..
The following query i have used.
impdp system directory=exportdump tables=SYNC.cin_document query=SYNC.CIN_DOCUMENT:'"where rownum<2570000"' dumpfile=satexpdpdump.dmp logfile=2570000d000gih.log CONTENT=DATA_ONLY
For your reference.:
The following scenario explains: 3 tables exported under scott. but we need to import only two tables. output follows

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

Any way to use filter to exclude tables in navagation pane?

Is there any way to use filter to exclude a set of tables from the table list in the navagation pane? I have a number of tables (15+) starting with the same prefix eg. AB123 that I would like eliminate from the list. They sort right to the top and I always have to scroll down, and go through the show more dialog to see the entire list.
I am sure I'm missing something, but not sure what. Help Center has nothing to offer.
Thanks
Glenn

This has been mentioned on the forum before - basically the need for more elaborate ways to filter (multiple conditions as well as 'not like'). It is on our list for future consideration, meaning post-production.

Exp/imp related problem

Hi all,
I have one problem in Oracle 9.2.0.8 onRHEL4. Iwant to use exp/imp to update one table from one server to another.
Suppose I have one table abc on A server and it is having around 1 million records and another B server is also having the same no. of records and some of the record have been changed to A server and i also want to imp the same record to another server B.Is there any paramneter in IMP.
Please suggest me.

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.
