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

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!
