Module jdk.naming.dns
Environment Properties
The following JNDI environment properties may be used when creating the initial context.
- com.sun.jndi.dns.timeout.initial
- com.sun.jndi.dns.timeout.retries
These properties are used to alter the timeout-related defaults that the DNS provider uses when submitting queries. The DNS provider submits queries using the following exponential backoff algorithm. The provider submits a query to a DNS server and waits for a response to arrive within a timeout period (1 second by default). If it receives no response within the timeout period, it queries the next server, and so on. If the provider receives no response from any server, it doubles the timeout period and repeats the process of submitting the query to each server, up to a maximum number of retries (4 by default).
The com.sun.jndi.dns.timeout.initial property, if set, specifies
the number of milliseconds to use as the initial timeout period (i.e., before
any doubling). If this property has not been set, the default initial timeout
is 1000 milliseconds.
The com.sun.jndi.dns.timeout.retries property, if set, specifies
the number of times to retry each server using the exponential backoff
algorithm described previously. If this property has not been set, the
default number of retries is 4.
