Ora-12154 = "I can not find the entry in the TNSNAMES.ORA file that I am using (regardless of the one YOU THINK I am using)!"

>1. TNSPING for the standby database server gives the positive result
Above only means you can get to listener, but in this case you are not even getting to the listener.

listener records into listener.log every connection request along with the appropriate status code STATUS=0 means success.

thanks for the response

Not understanding where the issue is exactly
Listener is up and running on both the servers.
Listener log

Please note that latest error is different from one in original post.

12518, 00000, "TNS:listener could not hand off client connection"
// *Cause: The process of handing off a client connection to another process
// failed.
// *Action: Turn on listener tracing and re-execute the operation. Verify
// that the listener and database instance are properly configured for
// direct handoff.  If problem persists, call Oracle Support.
// *Comment: The problem can be worked around by configuring dispatcher(s)
// to specifically handle the desired presentation(s), and connecting
// directly to the dispatcher, bypassing the listener.

Networking configuration is WRONG!
127.0.0.1 is "localhost"; the s/w is talking to itself on originating host.
(HOST=<ip_standby>) is what is required

Indeed the server is on the same machine.
I was just creating a test setup to move into the production later.
But i am not understanding being on the same machine , why the primary is not able to connect to standby.
Kindly help ?

What are SID for all the instances running on this system?

Is any type of Operating System virtualization running on this system?

Is there one ORACLE_HOME tree or two?
How many oracle listener processes are running?

post results from following commands

SET
lsnrctl status

post content of listener.ora & tnsnames.ora

>PING[ARCi]: Heartbeat failed to connect to standby 'orclstand1'. Error is 12154.
Above is a problem involving Primary not able to connect to standby

Below is a problem involving Enterprise manager not connecting to primary
>28-NOV-2009 22:29:24 * (CONNECT_DATA=(SID=orcl)(CID=(PROGRAM=\oracle\product\10.2.0\db_2\bin\emagent.exe)(HOST=EQ-W00300109765)(USER=OraUser))) * (ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=2920)) * establish * orcl * 12518

Which problem is highest priority to be solved?

I'm ask again, is any type of Operating System virtualization involved.

I contend
ORACLE_SID=orclstand1
is not the same as
ORACLE_SID=ORCLSTAND1

Test for yourself & see how Oracle responds
It does not matter if I am right or I am wrong.
It matters what works for you & what does not work for you.

I agree with the statement above.
I thought we were discussing Oracle's behaviour not Windoze.
I am not going to argue.
