Re: dbca and ASM

Did you review metalink note 365428.1 ?

The Problem lies with Oracle Net configuration. If either of the following parameters are set to anything other
than the default of "accepted" ,DBCA cannot communicate with the ASM instance.

SQLNET.ENCRYPTION_SERVER = accepted
SQLNET.ENCRYPTION_CLIENT = accepted

The problem was with encryption type of "DES40". After removing "DES40" from both SQLNET.ENCRYPTION_TYPES_CLIENT and SQLNET.ENCRYPTION_TYPES_SERVER communication between DBCA and ASM was re-established.

The problem is that DES40 was specified as one of the encryption algorithms and it doesn't play well with the jdbc
drivers. Per sections 5.1.2 of the 10.2 ASO guide, DES40 is not supported for jdbc clients
 Pasted below* *is the solution that it suggests..

Remove DES40 from Encryption Types

Old settings:

SQLNET.ENCRYPTION_TYPES_CLIENT= (DES40, RC4_40, RC4_56, 3DES112, 3DES168, AES256)
SQLNET.ENCRYPTION_TYPES_SERVER= (DES40, RC4_40, RC4_56, 3DES112, 3DES168, AES256) New settings that work:
SQLNET.ENCRYPTION_TYPES_CLIENT= (RC4_40, RC4_56, 3DES112, 3DES168, AES256) SQLNET.ENCRYPTION_TYPES_SERVER= (RC4_40, RC4_56, 3DES112, 3DES168, AES256)
