BindException when starting Tangosol

Question

Hi,
Our admin move the application using Tangosol to a new box and suddenly we start getting a BindException. The new machine has a new IP address, however the IP address below in the exception stack trace still references the old machine. And I don't even know where port 8088 is being set.
This cache is running in a distributed mode but there is no out of process cache running on the previous machine.
can someone tell what this error might indicate ?
nested exception is (Wrapped:
UnicastUdpSocket{State=STATE_INITIAL, address:port=10.58.33.162:8088})
java.net.BindException: Cannot assign requested address

Hi,
the IP address can explicitly be set by the Java property -Dtangosol.coherence.localhost=..., where ... is the explicit address.
This has probably been set somewhere (Java property, override file), if your stacktrace refers to an IP address which is not present in the box.
The 8088 port is the default unicast listener port, and can be set by setting the -Dtangosol.coherence.localport=... Java property, but by default automatic increment of the port is enabled so if it is bound then it is automatically incremented. Note that this is not recommended for production mode (probably due to the problems which can be caused by firewalls filtering out unexpected traffic which comes to/from a port which is different from the expected due to autoincrementing).
See more about this in the following URLs:

Override file:

Best regards,
Robert
