Issue/Introduction

I received a mail from our network team that our IXP servers are generating high number of queries and causing huge traffic on the DNS servers.

From ixpDaemon.log, I could see there are many UnknownHostException message in the log.

Is there a way to suppress this messages or skip checking of IP address please?

Environment

Release : 11.3

Component : CA WORKLOAD AUTOMATION AE IXP

Resolution

When report-down or report-pingable options is enabled (which it is by default) you might notice an error like below. 

db-ACE:unable to determine IP address:1433;databaseName=AEDB_ACE;user=autosys;password=autosys;:java.net.UnknownHostException:1433;databaseName=ACE;user=autosys;password=autosys;

Recommendation:

Disable DB pingable check: Set following variable on iXp server startup line (same place installation has you add -Xmx1500m entry):
-Dixp.server.db.report.host.reachable=false

Restart ixp
