Yup, saw that one.  Not an issue:

% cat $ORA_ASM_HOME/network/admin/sqlnet.ora:

# sqlnet.ora.NODE1 Network Configuration File: 
/u01/app/oracle/product/10.2.0/asm/network/admin/sqlnet.ora.NODE1
# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

NAMES.DEFAULT_DOMAIN = corp.acxiom.net

Subject: 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)

Folks,

I'm trying to create a database on my RAC cluster with ASM.  This is on 
10.2.0.3 and RHEL4 64bit.  ASM is up and running on both nodes (only 2-node 
cluster) and I've got valid diskgroups in each.  Checking crsstat it shows all 
services are up, as in ASM, LISTENER, gsd, ons, vip on both nodes. 

Now for creating a database.  I thought dbca would be the way.  But in the 
process, I believe step 7, I'm asked for the storage to use.  I pick ASM, then 
"next".  At this point I get the message: "DBCA could not startup the ASM 
instance configured on this node.  To proceed with database creation using ASM 
you ...". 

I can't figure out why dbca can't see my ASM instance.  I've tried setting 
ORACLE_SID=, ORACLE_SID=+ASM, ORACLE_SID=+ASM1 (local instance on this server 
of ASM), all run out of $ORACLE_HOME/bin, not $ORA_ASM_HOME/bin.  Each try 
gives me the same error. 

Any clue how to get dbca see your existing ASM instances?  Is there any way to 
find out what exactly is failing behind the scenes?  I've set tracing for dbca 
(-DTRACING.ENABLED=true -DTRACING.LEVEL=2 in the last line of dbca), but that 
doesn't output anything after first starting up. 

Any help would be GREATLY appreciated.  Thanks.

Dave
