Re: MINA3.0 recommended

Re: Detecting non-idle but non-active either sessions

Are you referring to TCP sockets or some kind of protocol over TCP? In MINA idle and non-active are same thing. Either data is received on the socket or not. If data isn’t received and the idle timer is configured, then idle events are dispatched and the IoHandler can use that event to take the

It’s not a port it’s a File Descriptor. The socket events are handled by a selector which uses 1 File Descriptor. There is usually one per processor. You can manually set the number of socket processors. On Fri, Mar 16, 2018 at 11:49 AM Simo Chiegang, Boris Arthur < boris.s...@heidelberg.com>

Mina is a queue and flush framework. All writes are queued up and scheduled later using the poll/kqueue system. The ExecutorFilter uses threading to process incoming messages using a pool of threads instead of the reactor/processor thread. This frees the processor thread to do IO. Have you

Looking at the code for your existing filter it appears like you’re just trying to create the SSLEngine so it can be reused for subsequent connections by passing in the IP address and Port? This is already a feature in the new filter.
