Encryption in EXPDP

Dear DBAs,
Is there a way to encrypt a backup dump using expdp in oracle10g ??
Actually the tables are not encrypted and i only want to encrypt the backup dump.
thanks in advance for your help

DataPump is not a backup. If you want a backup. And you want encryption. Use the correct tool: RMAN.
But just to answer your question a demo of export encryption can be found here:
http://www.psoug.org/reference/datapump.html
The fact that this demo exists should not be taken as an indication that encryption does not require additional licensing: It may. Check with your Oracle sales rep.

TDE (Encryption) and expdp (Datapump)

Hi,
I'm testing TDE's features on an Oracle 10g R2 database. I edit the sqlnet.ora then I created a wallet on database 1 (DEV1), a table, did inserts, pumped (expdp) data and tried re-import it in another database (DEV2) which I use with DataGuard for failover, but something went wrong. So I try re-create my wallet on the first database (DEV1) by alter system set wallet close and delete it from my hard drive and drop table purge. I went trought the whole process of creating the wallet and table but when I tried expdp I got the ORA-28362 master key not found.
How could I not be able to export my data ? What can I do to do a clean deletion of the wallet and recreate it ?
Thanks for you help
Francis

Thank you,
but I already read those pages and understand them. But as I said, even though I delete and recreate the wallet, I can't get datapump to extract data with the ENCRYPTION_PASSWORD parameter. If I don't put this parameter everything is ok! but the data is not encrypted.

Encryption - expdp

I am on 10.2.0.4 and want to encrypt the password while using expdp on a scheduled job. What is the best way?
Thanks.

Eg: expdp userid=user/pwd@db full=y etc.,
When you schedule a the above export as job, is there a way to encrypt the password?
Thanks!Use of Oracle Wallet Manager may be a solution for you.

Expdp error anyone have an idea on how to fix this?

I'm trying to get an export of a database that has encrypted columns. Exp really isn't a good option I'd have to unencrypt the columns first everytime.
First I create the directory D:\DPDUMP and give Everyone SERVICE and SYSTEM full rights to the directory. Oracle runs as the Local System account.
Created new user myuser that has the role DBA with EXP_FULL_DATABASE etc.
Made directory object.
CREATE DIRECTORY dpump_dir_01 AS 'D:\DPDUMP';
grant read, write on directory dpump_dir_01 to myuser;
Run expdp as myuser with following PARFILE entries just testing on the tables that are giving me problems.
DIRECTORY=dpump_dir_01
LOGFILE=Encryptest.log
DUMPFILE=Encryptest.dmp
FULL=N
encryption_password=********
TABLES=MYBANK.CARDAGREEMENT
CONTENT=ALL
get errors
ORA-39006: internal error
ORA-39213: Metadata processing is not available
I've added USERID="/ as sysdba" to the PARFILE.
I've tried it to the default DATA_PUMP_DIR after giving read write to that with the same error. expdp TABLES=MYBANK.CARDAGREEMENT.
No matter what I do I get this error. So far what I've seen is a Directory permissions issue normally causes it and granting access fixes it but I'm having no luck at all.

Here the error definition message, have you try the recommanded action ?
ORA-39213: Metadata processing is not available
Cause: The Data Pump could not use the Metadata API. Typically, this is caused by the XSL stylesheets not being set up properly.
Action: Connect AS SYSDBA and execute dbms_metadata_util.load_stylesheets to reload the stylesheets.

Encrypt datapump in oracle 10g

Hi, I have an Oracle RAC SE 10gR2 (10.2.03) with 3 nodes on SLES 10 on ibm ppc.
Every night I have some oracle exports (expdp) of some schemas. I want to encrypt one of various datadumps throught a shell bash script. I see that exists TDE for encrypt colums in a table, and I have to create a wallet for encrypt. However, I'm thinking that I preferred clear text (no encrypt in my tables and schemas) and only encrypt the datapumps files. For example, I have my database same as now, and I should specify one options in my expdp for encrypt.
It's possible?
Can I encrypt those datapumps without use TDE (in Oracle 10g)?
Thanks you very much!!

How to conduct Tablespace encryption in 11gR1

hi,
i recently completed 10g upgrade to 11gr1 (11.0.6). upgrade is completed and successful.
Now there is 1 read only tablespace which has HR data(ssn, credit card, birth date etc) which i need to encrypt.
I know high level steps is
1; use expdp table the tablespace export
2: drop the tablespace
3; recreate new encrypted tablespace
4:import into new encrypted tablepsace
i have not used expdp and encryption in past.
what syntax i need to use for expdp to conduct tabelspace export.

So following steps have valid syntax?
sqlplus " /as sysdba"
sql>drop tablespace lawtbs;
sql>ALTER SYSTEM SET ENCRYPTION KEY IDENTIFIED BY “lawtbs011”;
sql>CREATE TABLESPACE lawtbs
DATAFILE ‘/u01/app/oracle/oradata/lawtbs_data_01.dbf’ SIZE 2040m,

How to make a dmp file for a table contains encrypted column/s?

Hi All,
I've created a table with encrypted columns using TDE (Wallet). When I tried to make a dmp file by this command:
exp system/password file=<path>\ex.dmp owner=ex
the command pormpt gives this error: Feature (COLUMN ENCRYPTION) of column EMP_SSN in table EX.EMPLOYEES is not supported. the table will not be exported.
How to solve this problem?
I want to make a dmp file which export data of encrypted column in an encrypted format not clear format. How?
Note:
there is a parameter: ENCRYPTED_COLUMNS_ONLY: Encrypted columns are written to the dump file set in encrypted format

Data Pump Export with Column Encryption

Hi All-
I have the following two questions:
- Can I export encrypted column data to a file, preserving the data encrypted? (ie. I don't want clear text in resulting file)
- If yes, what would another person need to decrypt the generated file? (ie. I want to give the resulting file to a customer)
Thanks a lot for your help!
Juan

Hi,
expdp and impdp works only on oracle database. You you need to have oracle database on source and destination to use expdp/impdp. You can also use expdp with ENCRYPTION_PASSWORD option so that password can be passed to client for doing impdp at their end with given password.

How to make export with sensitive user data encrypted?

My organization need a backup dump of prod database sent to a customer, but want me to encrypt some user's password, and some data.
Which expdp parameter can do that?
Or any way I can do that ?
Thanks in advance.

Transparaent Data Encryption

Hi all,
Is Transparent data encryption method is available in oracle 10g release 1 ?
In release2 i can able to do TDE with wallet manager but it is not possible to do in oracle 10g release 1 and i can able to find dba_encrypted_columns in these release, kindly guide me is there any script or method to be used inorder to configure manually

Hi,
It's Purpose is to copy (Loading) source schema into a target schema.
Suppose that you execute the following Export and Import commands to remap the hr schema into the scott schema:
expdp SYSTEM/password SCHEMAS=hr DIRECTORY=dpump_dir1 DUMPFILE=hr.dmp
impdp SYSTEM/password DIRECTORY=dpump_dir1 DUMPFILE=hr.dmp REMAP_SCHEMA=hr:scott
In this example, if user scott already exists before the import, then the Import REMAP_SCHEMA command will add objects from the hr schema into the existing scott schema. You can connect to the scott schema after the import by using the existing password (without resetting it).
If user scott does not exist before you execute the import operation, Import automatically creates it with an unusable password. This is possible because the dump file, hr.dmp, was created by SYSTEM, which has the privileges necessary to create a dump file that contains the metadata needed to create a schema. However, you cannot connect to scott on completion of the import, unless you reset the password for scott on the target database after the import completes.
You can map different source schemas to the same target schema.
Thanks

Expdp from diff home

Hi
if i m having two oracle home 10g and 11g on same server and i want to do expdp of 11g database from 10g home is it possible ?
for exp it is possible but i m not able to do it using expdp
plz suggest

Carlovski wrote:
OK, yes, you could use the expdp utility to launch it from a different oracle home, but it's just a wrapper to make the appropriate calls to DBMS_DATAPUMP.
I'm not sure if doing so would automatically set the coorect 'VERSION' parameters for you.
I really don't see why you would want to do such a thing though.
CarlYou have a good point indeed, Oracle is not setting the correct version...

Unknown parameter name 'ENCRYPTION'

Hi All,
I've made a dmp file using expdp for a table containing encrypted coulums.
But when I tried to use ENCRYPTION parameter to enable encryption of data in dump file sets the command pormpt gives this error:
unknown parameter name 'ENCRYPTION'
My DB Version: 10.2.1.0.1

Dev. Musbah wrote:
It stills giving the same error: unknown parameter name 'ENCRYPTION'
Does this parameter can't be used in DB 10g Release 2?Please see the docs or the help with the command. There is no such parameter in data pump.

Incremental EXPDP !!!

Dear all,
I have a production database on windows 2003 server 64 bit with oracle 10.2.0.3 installed. This db has a schema which expdp file is of 33gb, every day I am taking the schema level export and importing the same to my test server.
Moreover, we also had configured flashback database.
Its taking a lot of time to import everyday despite there is little changes in the schema. Our intention is to refresh the test schema every day.
Is there a way to take the incremental expdp/flashback to record only the changes and then import it into the test server.
Thanks.
