Unable to view log or output for any concurrent request

We get the following error message (both for log and output):

<< An error occurred while attempting to establish an Applications File Server connection with the node FNDFS_hostname01. There may be a network configuration problem, or the TNS listener on node FNDFS_hostname01 may not be running. Please contact your system administrator.>>

Solution:

This is because of hostname02 entry which was missing in sqlnet.ora of hostname01 .    Looks like autoconfig was not executed on first node after second node configuration.

tcp.invited_nodes = (EXT_HOSTNAME01, DB_HOSTNAME.domain_name, HHOSTNAME01.domain_name, HOSTNAME02, EXT_HOOSTNAME02)

HOSTNAME02> this entry was missing ,added it and it went.
