Listener not working in one of the servers of the Standby site

Hello,

The system is a RAC with two servers working as Primary site, and two servers working as Standby site.

Both servers of the Primary site are sending redo logs to one of the servers of the Standby site. The other server of the Standby site is not receiving any redo log.
I have checked the listener.ora and the tnsnames.ora files of the server that is not receiving and it is well configured comparing it with the server that is receiving the redo logs.

If I check the status of the listener: lsnrctl status listener_
Both of the Standby servers look fine.

But if I connect directly to the database...

In the 1st server of the Standby, the IP appears:

SQL> show parameter listener

NAME TYPE VALUE
-------------------------------------------------------------------------
local_listener string (ADDRESS = (PROTOCOL = TCP)(HOST = xxx.xxx.xxx.xxx)(PORT = xxxx))
remote_listener string LISTENERS_VSDB

Nevertheless, in the second server of the Standby site, the one that is not receiving the redo logs, the IP does not appear:

SQL> show parameter listener

NAME TYPE VALUE
----------------------------------------------------------------------
local_listener string (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = xxxx))
remote_listener string LISTENERS_VSDB


I have found the following to reload the listener:

Oracle# lsnrctl reload listener_`hostname`
Oracle# lsnrctl reload listener_standby

Has anyone tried this? Did it work? It can be run without affecting the sytem, Dataguard, replication..., right?

If you have another idea to fix this, let me know please.

Thank you ;)

What do you see when doing... lsnrctl status listener_standby ?

In the first server of the Standby site:

#lsnrctl status listener_standby

Seems listener are up and running on both nodes of standby,check the alert log on 2nd server of standby for any errors and make sure the password for sys is same as that of the primary and you have a passwordfile on 2nd node of the standby and make sure you have proper tns entries on primary for the standby .

can you connect to both the standby server through sqlplus?

Thanks Rayyah.

There are no errors in the alert log of the second server of the Standby site. It only does not receive redo logs from the Primary.

The sys passwords are the same and I can connect from any server to every server of the Primary and Standby.

How can I check the passwordfile in the 2nd node of the Standby?

How can I check that the Primary server would send redo logs to the 2nd node of the Standby if the 1st node fails?

Thanks

I've just checked that when I connect from the Primary site to the 2nd server by SQL I can see in the log the conexion is right:

29-OCT-2009 19:12:25 * (CONNECT_DATA=(SERVER=DEDICATED)(SID=DB2)(CID=(PROGRAM=sqlplus@server1b)(HOST=server1b)(USER=root))) * (ADDRESS=(PROTOCOL=tcp)(HOST=IP_2nd_server_Primary)(PORT=xxxx)) * establish * DB2 * 0

How can I check that if the 1st server of the Standby fails, then the Primary servers will send the redo logs to the 2nd Standby server?
