    • PRVF-5636

    Description

    When cluvfy finds outthat nslookup name resolution for an

    unknown host takeslonger than 15 seconds, it issues error

    PRVF-5636.

    eg:

     PRVF-5636 : The DNS response time for anunreachable node exceeded

                 "15000" ms on followingnodes...


    Checking the file "/etc/resolv.conf" to make sure only one of domain and search entries is defined
    File "/etc/resolv.conf" does not have both domain and search entries defined
    Checking if domain entry in file "/etc/resolv.conf" is consistent across the nodes...
    domain entry in file "/etc/resolv.conf" is consistent across nodes
    Checking if search entry in file "/etc/resolv.conf" is consistent across the nodes...
    search entry in file "/etc/resolv.conf" is consistent across nodes
    Checking file "/etc/resolv.conf" to make sure that only one search entry is defined
    All nodes have one search entry defined in file "/etc/resolv.conf"
    Checking all nodes to make sure that search entry is "oracle.com" as found on node "rac2"
    All nodes of the cluster have same value for 'search'
    Checking DNS response time for an unreachable node
      Node Name                             Status                  
      ------------------------------------  ------------------------
      rac2                                  failed                  
      rac1                                  passed                  
    PRVF-5636 : The DNS response time for an unreachable node exceeded "15000" ms on following nodes: rac2
     




    The expectation isthat the user fixes the DNS so that name resolution

    for unknown hosttakes less than 15 seconds.  The aboveerror message

    printed by cluvfy didnot make this expectation clear. 

     

    With the fix for thisbug, the error message makes it clear that

    name resolution forunknown host should take <= 15s.

     

    Please note that evenwith the fix, nslookup for unknown host should

    still take <15sand cluvfy will still fail if it does not. With the fix,

    the difference isthat the error message will be clearer.

     

    Workaround

     There is no workaround to change the errormessage.

     To stop getting the error, engageSystem/Network Administrator to find

     out why nslookup for unknown host takes solong and fix it.

     

    Please note: The above is a summary description only. Actual symptoms can vary. Matching to any symptoms here does not confirm that you are encountering this problem. For questions about this bug please consult Oracle Support.
