Dear All,
i am testing Transparent Data Encryption in Oracle 10g by using the following link
http://oracle-base.com/articles/10g/TransparentDataEncryption_10gR2.php
Before Implementing the TDE listener was running fine but after implementation of TDE the listener was unable to start
Please check the steps which i follow
Step1-
specify the ENCRYPTION_WALLET_LOCATION parameter in the sqlnet.ora file, now SQLNET.ora file looks like the following
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
ENCRYPTION_WALLET_LOCATION=
(SOURCE=(METHOD=FILE)(METHOD_DATA=
(DIRECTORY=D:\oracle\product\10.2.0\wallet\)))
please check the contents of listener.ora file,i didn't make any configuration changes for listener before or after implementation of TDE
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = shakeel-pc.lhr.inov8.com.pk)(PORT = 1521))
)
)
Step2-
CONN sys/password AS SYSDBA
ALTER SYSTEM SET ENCRYPTION KEY AUTHENTICATED BY "myPassword";
TDE implemented successfuly implemented.
But when i try to stop/start listener

TNS-12560: TNS:protocol adapter error
TNS-00583: Valid node checking: unable to parse configuration parameters
Listener failed to start. See the error message(s) above...
To start the listener i have to close wallet as
1- SQL>conn sys as sysdba
[B][B]ALTER SYSTEM SET WALLET CLOSE;[/B][/B]
2- Replace the SQLNET.ora file as previous ,now SQLNET.ora contains
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
Now after making the changes revert back to previous config before TDE if i start the listener then the listener was started succesfuly
Please suggest!
