SQL & PL/SQL :: Trigger Fired - Final Update To Base Table Not Happening
Jul 1, 2011In my DB,We have a table rqst_list
Create table rqst_list(id Number, --(PK)
pkg_name varchar2(100),
status varchar2(100))
When a record is inserted into this table(rqst_list), a trigger is fired which calls the package which is there in pkg_name.The function does some function.If there are no exceptions while executing the package, then SUCCESS needs to be updated in the table for the id for which the trigger got fired.I have used AFTER INSERT ROW level trigger.
But,the final UPDATE (UPDATE the rqst_list table to SUCCES/FAILURE)to the base table inside the package is not happening.

Backup & Recovery :: Tape Streaming Not Happening While Performing RMAN Backup
Oct 29, 2011Tape streaming is not happening while performing RMAN tape backup. On investigation, you find that it is not because of the incremental backup or the empty file backup and that RMAN is sending data blocks to the tape drive fast enough.What could be a solution to make tape streaming happen during the backup?
A.Configure backup optimization
B.Configure the channel to increase MAXOPENFILES
C.Configure the channel to increase the capacity with the RATE parameter
D.Configure the channel to adjust the tape buffer size with the BLKSIZE option

Security :: Oracle Password Encryption
Oct 10, 2011While 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.

Server Administration :: Set-up Network Encryption
Sep 9, 2010I am trying to set-up network encryption.I have added following parameters to my server side sqlnet.ora file:
SQLNET.ENCRYPTION_SERVER = REQUIRED
SQLNET.ENCRYPTION_CLIENT = REQUIRED
SQLNET.ENCRYPTION_TYPES_SERVER =RC4_256
SQLNET.ENCRYPTION_TYPES_CLIENT =RC4_256
SQLNET.CRYPTO_CHECKSUM_SERVER = REQUIRED
SQLNET.CRYPTO_CHECKSUM_CLIENT = REQUIRED
SQLNET.CRYPTO_CHECKSUM_TYPES_SERVER = (MD5)
SQLNET.CRYPTO_CHECKSUM_TYPES_CLIENT = (MD5)
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.

Security :: Data Encryption From Transaction To Backup Level?
Apr 26, 2013Our 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.
Wallet - While Creating A Table Says Master Encryption Key Is Not Present?
Jan 22, 2013I 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.

2) DB Encryption (But if we encrypt ALL columns Serious performance issue expected, File level will not restrict DB level access)

RMAN :: Encryption / Decryption When Using RMAN To Duplicate / Clone?
May 8, 2013Given facts:
rman is used to backup database A to disk
rman is used to put those disk backups to tape
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?

Application Express :: Hyperlink Column With Link Parameters As Region Column Values
Apr 10, 2013On my APEX page i have region which has sql query as source and it displays as HTML table the query result to the user.
I want to display addinonal column with a hyperlink inside, and that hyperlink would have CGI/URL-parameters which contains the other values of the HTML row.
So, let's say my APEX region queryes columns as "select c1, c2, c3, c4 ..." and displays out values "V1, V2, V3, V4" then i want to have addional output column with such hyperlink:
a href="f?p=100:7:13467554876288::NO::c1,c2,c3,c4:v1,v2,v3,v4">My link column with CGI-parameters</aHow can i create such hyperlink?
The overall idea is that the link would forward to a page which loads those values "v1,v2,v3,v4" into form fields and user can proceed from there.

Reports & Discoverer :: Value In Table Column Based On Some Existing Column Value Automatically Without User Intervention
May 15, 2011i have two questions.
(1) how can i fill some value in a table column based on some existing column value automatically without user intervention. my actual problem is i have 'expiry date' column and 'status'. the 'status' column should get filled automatically based on the current system date. ex: if expiry date is '25-Apr-2011' and current date is '14-May-2011', then status should be filled as 'EXPIRED'
(2)hOw can i build 'select' query in a report (report 6i) so that it will show me list of items 'EXPIRED' or 'NOT EXPIRED' or both expired and not expired separately in a single report based on user choice. 'EXPIRED' & 'NOT EXPIRED' can be taken from the above question no. 1.

value n
Since the column is small it can fit in a page more then one time. I know how to make it print more then once: i switch the repeating frame to print down and across and i modify the frame that contains it so the horizontal elasticity is variable.
After these changes my report looks like this:
