Oracle Database Discussions

I installed Oracle11gR2 GRID and RAC on two nodes(windows2008R2): I did some modification for supporting TAF failover.

when I do "tnsping" I got an error like:

C:\Users\administrator.QAPF2>tnsping NLQA

TNS Ping Utility for 64-bit Windows: Version 11.2.0.3.0 - Production on 16-APR-2

Used parameter files:
C:\app\11.2.0\grid\NETWORK\ADMIN\sqlnet.ora


Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION =
TNS-12533: TNS:illegal ADDRESS parameters

From oracle forum, there were many discussions on this error: due to some bad characters in tnsnames.ora file.
They suggest to use NetCA to create it, I tried as follow but I got another(maybe same) error:

Connecting...ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
The test did not succeed.

Current node1 status:

My TNSNAME.ora file:

)

listener.ora file:

I can not connect to the OracleRAC server from client. Please help me.

Thanks
