Use this command-line option to enable and disable network queries from being used to determine the host name and IP address for RAS (reliability, availability, and serviceability) troubleshooting purposes.
OpenJ9 captures the host name and IP address by default, for use in diagnosing problems. But if a nameserver cannot be contacted when a network query is made, the program will wait until the resolver times out.
You can avoid this situation by using the
-XX:-ReadIPInfoForRAS command-line option to prevent the query from being performed.
