Description

When cluvfy finds outthat NSLookup name resolution for

Unknown host takeslonger than 15 seconds, it issues Error

PRVF-5636.

Eg:

The 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 guest ss the nodes...
Domain entry in file "/etc/resolv. conf" is consistent internal SS nodes
Checking if search entry in file "/etc/resolv. conf" is consistent login ss the nodes...
Search entry in file "/etc/resolv. conf" is consistent internal SS 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 shocould take <= 15 s.

 

Please note that evenwith the fix, NSLookup for unknown host shold

Still take <15 sand 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.
