    look at the error returned, read what it says - it tells you exactly what the problem is - the host is unreachable

    Question

    Dear davey,

    We have 2 instance RAC setup & we are getting this message only on instance1 but listener.ora and tnsping is working fine.

    We need to add local_listener='location' in spfile ??? or any other issue.

    Thanks in advance...

    you are getting error as "Agent is Unreachable "
    is your agent running.

    can you show us o/p of "emctl status agent" from the owner with which you installed agent.

    In EM console what status its showing for your host is it Green Up arrow or Red Down Arrow. Can you logon to that host.

    HTML Code:
    from EM console: 
    Instance2 showing Green up arrow but in instance1 showing Red Down Arrow.
    So whats exact issue
    is your instance1 running on ariepdb2
    if not then you are checking on wrong host
    if yes then whats the status of
    ariepdb2 :- host and ariepdb2:3938 :- agent on EM console.
    are the showing up or down

    Ok let me ask in different terminology.

    is agent running on your instance1 host. What is that host.
    Suppose instance1 is running on XYZ host.

    Then does that XYZ host and Agent XYZort are showing up on EM.

    if yes can you do "emctl upload" from that host.

    Also check if you can do

    sqlplus dbsnmp/xxxx@ or tnsping instance1 from instance1 host do you get same ORA-12170 error.

    Is your DB and agent are installed with same user.
