xavier roques commented on SEQUOIA-918: --------------------------------------- Warning, very often the routers block the broad casted network packet. > Driver pinger may break in configuration with multiple interfaces > ----------------------------------------------------------------- > > Key: SEQUOIA-918 > URL: https://forge.continuent.org/jira/browse/SEQUOIA-918 > Project: Sequoia > Type: Bug > Components: JDBC Driver > Versions: Sequoia 2.10.4, Sequoia 3.0 beta3, Sequoia 2.10.5, Sequoia > 2.10.6, Sequoia 2.10.3 > Reporter: Marc Herbert > Assignee: Gilles Rayrat > > > The driver pinger currently identifies answering controllers by looking at > the source address of the pong answer packet. If the controller has multiple > network interfaces, it may return the "Pong" packet using an address unknown > to the driver, breaking the ping scheme. > One fix would be to use UDP on _connected_ sockets. But connected sockets is > probably overkill and a resource waste. > This seems to be a simpler fix: the driver sends a controller ID to the > controller, and the controller just returns it. (this controller ID can be > private to the driver) > It should be possible to implement this in a backward compatible way. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://forge.continuent.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira _______________________________________________ Sequoia mailing list [email protected] https://forge.continuent.org/mailman/listinfo/sequoia
