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.
