I would like to know the reason why the database is on unencrypted format by default,there must be some reason behind this, i hear from someone that encrypted data degrade performance thats the reasons its on unencrypted format by default.
I installed Oracle 11g and created a test database in that the default count should be 4196... but it is 4143.. some packages are missing.. even when i'm creating materialized view it is showing some error that packages are missing. what can i do for that? Is my oracle s/w corrupted ? even when i downloaded from oracle site it also shows the same count.
I have created a form. Some of the elements are hidden such as updated_by and update_date. I have provided the default values for these attributes as pl/sql expression in the "default section" (Application->page->edit page item). I am using the Process Row process that is automatically created when a form is created.
The problem is when I click the update button, the updated_by and update_date is passed as null values which throws an error from the database.
I encrypted the column but when i check through strings command the data is still not encrypted,i created the wallet etc etc,set proper path in sqlnet.ora

SQL> ALTER SYSTEM SET ENCRYPTION KEY AUTHENTICATED BY "XXX"; ALTER SYSTEM SET ENCRYPTION KEY AUTHENTICATED BY "XXX" * ERROR at line 1: ORA-28368: cannot auto-create wallet
As you can see the directory is not created.
ls -ld /oracle/10.2.0.1.0/network/admin/encryption_wallet ls: 0653-341 The file /oracle/10.2.0.1.0/network/admin/encryption_wallet does not exist.
The directory above where I want to create my wallet is owned by oracle, which is the user I am running sqlplus as (see below)
While searching for password encryption I came across these statements.
1.Password Encryption While Connecting. This protection is always in force, by default. Passwords are always automatically and transparently encrypted during network (client/server and server/server) connections, using a modified DES (Data Encryption Standard) or 3DES algorithm, before sending them across the network.
Confirm whether by default oracle encrypts the password before sending it to the database across the network even when the clear text password is used for connecting from a jdbc client.
I am trying to have an encryption logic written in Pl/SQL that could decrypt the value which is encrypted in Dot Net, using AES128 algorithm. Everytime when i try to have the decryption done, i lands up in one or the other error message. Below is the code snippet which i use. create or replace
FUNCTION decryptAES (EncryptedText IN VARCHAR2,EncKey IN VARCHAR2) RETURN VARCHAR2 DETERMINISTIC IS key_bytes_raw RAW (2048); l_ decrypted_raw RAW (2048); encryption_type PLS_INTEGER := DBMS_CRYPTO.ENCRYPT_AES128; BEGIN key_bytes_ raw:= UTL_RAW. CAST_TO_ RAW (EncKey); l_decrypted_raw := dbms_crypto.decrypt (src =>utl_raw.cast_to_raw(EncryptedText), typ => encryption_type, key => key_bytes_raw ); RETURN (UTL_RAW.CAST_TO_VARCHAR2 (l_decrypted_raw)); END decryptAES.
As per my understanding connections should start to fail from client side after addition of these parameter on server side sqlnet.ora (no changes to client side sqlnet.ora).I am still able to connect to this server without connections getting failed.
I already checked aso is installed on this database.Just to add it is a RAC database with 2 nodes.
Can i get some documents on oracle RAC database encryption.?what are the pros and cons of encryption?Does this comes with oracle Database or something we need to buy from oracle sales persons?
We are attempting to configure/use OEM (Oracle 10.2.0.4) on Solaris, and when logging in to OEM we are directed to the Database Down page, stating Enterprise Manager is unable to connect to the database instance, but showing all the components as up/open. After checking the log, I found the following error:
IO exception: Unknown Encryption or Data Integrity algorithm
I checked the settings in emoms.properties and compared the encryption parameters to those in our SQLNet file, and all match up. We are NOT using Grid Control, just db control connecting to 1 instance.

Our Audit Company has given us a recommendation:"Old DB Link encrypted Passwords: The password of the Oracle databases links are encrypted using DES (password starts with 05). This encryption methord is known and users can decrypt the passwords using a simple SQL query. Please recreate the database links to use the new encryption method (password starts with 06)."What does it mean and how can we perform this recommendation?
Recently the Oracle10g database has been migrated to UTF8 character set and the following have failed.
1. The password applied is not getting encrypted and the password contains a spanish characters.
Getting the below error.
"10057:ERROR WHILE ENCRYPTING GIVEN STRING:String:Uñomasuño5.::ORA-28232: invalid input length for obfuscation toolkit:-28232:ORA-28232: invalid input length for obfuscation toolkit"
The algorithm used for encryption DES. I tried with DESENCRYPT , DES3ENCRPYT and MD5 and it failing.
Our client is having requirements that data should be encrypted through-out the process (from transaction level to backup level).
Requirements are as below -
1) Data should be encrypted and can be access only through application (through front end). 2) Even if pl/sql, sql installed, developer user cannot able to fetch data from database. 3) Even DBA, should not have access to fetch the data from the database. 4) Only assigned DBA, should fetch details from database (provided he/she should have details of database as well as application's user / password). 5) It should be restricted by ip and user details (such as ip of application server with user/password of user). 6) Changes should be purely done from database level only.
I have created a wallet (11g R2 OEL 5.5) using the OWM.Tried opening the wallet (encryption_wallet_location set in sqlnet.ora). then while creating a table it said the master encryption key is not present. Have created the master key using the following command.
alter system set encryption key identified by "Password";
Here the strange thing i observed is that when we create a wallet using the OWM, it asks for the password and when i open the same wallet the master key is not created and it allows the master key to be generated with the same password that i have created the wallet in the first place with the OWM, with any other passwords it says that the wallet is not open.
After creating the wallet and creating the master key... I have the following questions, and its becoming quite hard to find the solutions as well.
1. Can we have multiple encryption keys... say i want to encrypt a table or column with one key and other with an another key. 2. How many keys can we have for objects in the table? or can we have only one key and many certificates. 3. wallet created, and encrypted tables present, the wallet is not in auto open mode, but somehow the database open after it is shutdown, here no encrypted tablespaces are present. 4. while creating an encrypted tablespace the default storage (encrypt ) has to be added to the add tablespace clause.
We have got a new requirement wherein, The customer wanted the DBA Vendor (US) NOT to access the confidential information (ALL Columns) in the DB tables of PRODUCTION database. This is for few applications to comply with with export control rules. The thin support by Customer DBA will be allowed to access the Data, if required .
1) Web Based Interface ?. 2) DB Encryption (But if we encrypt ALL columns Serious performance issue expected, File level will not restrict DB level access) 3) Special setting on DB (DBA to do only backup and restoration related work only - But cannot access data) 4) Standard Tools / Utilities / Others ??.
We have an application that fetches and writes data into oracle database through pro c. oracle datyabase is on another server.
We are storing some secure information into oracle database so we want to encrypt the data sent by our aplication into oracle database.We do not want to use SSL(i.e certificates) and also do not want to make use of Advance Security Option available in oracle and also do not want to make any changes in sqlnet.ora file on server side.
achieve encryption of traffic between our application and Oracle database?
rman is used to duplicate database A to database B on another host
the duplicate process worked fine before we started testing encryption
the duplicate process worked fine with database A having an encrypted column in one table in a non-encrypted tablespace
Now, database A has an encrypted tablespace with nothing currently in it. The duplicate process now ultimately fails with ORA-19913, unable to decrypt backup.
I am not using encrypted backups, not specifying encrypt or decrypt anywhere in the duplication process. The only thing that is encrypted is the one tablespace in database A. I have the same wallet files on Host A (database A) and Host B (database B). Wallets are open. So why does the duplication process fail because the backup cannot be decrypted?
I wanted to know the consequences of adding a DEFAULT value to an existing column in a table.I understand that when you add a DEFAULT value to a column which is Nullable, Oracle updates all the null values for the column to the DEFAULT value, generating a lot of undo/redo data.
Is adding a DEFAULT value to a NOT NULL column a problem? As the column is NOT NULL, an update would not be done, so no undo/redo data will be generated.But will this cause a whole table scan? Is this advisable?
I am working on forms 6i. I have set where condition in pre-query of a trigger, my requirement is, in post-query, i want to delete the where condition.
pre-query:
set_block_property('HEADER_S',default_where,'STATUS IN (select meaning from XXSMCQSS_LOOKUP_VALUES where lookup_type=''CONCESSION STATUS CODES'' and primary_flag=''N'' )');
post_query: I want to delete this where condition, i just want make execute query normal by removing the where condition.
