Dear Wiki user, You have subscribed to a wiki page or wiki category on "Tomcat Wiki" for change notification.
The "TomcatGridDiscussion" page has been changed by theimpaler: https://wiki.apache.org/tomcat/TomcatGridDiscussion?action=diff&rev1=15&rev2=16 1. It's assumed that a port will be accessible from each Grid Manager to each machine where the Grid Agents are serving. The firewall, if present must allow active server-type sockets on that port. * ''__markt__: Another architectural question. Which end opens the connection, does it stay open and which protocol is used? For example, agents connect to Manager via WebSocket.'' - * ''__vlad__: I always considered the Grid Agent would would open a server NIO socket, to avoid using ephemereal ports. The Grid Agent is always listening, and the Managers connect when needed.'' + * ''__vlad__: I always considered the Grid Agent would would open a server NIO socket, to avoid using ephemereal ports. The Grid Agent is always listening, and the Managers connect when needed. In terms of protocol, it could be a ad-hoc one, specially developed for this tool, or use a well-known standard. I have ad-hoc one that I can use, but I'm open to suggestions.'' 1. Multiple Grids (and Grid Agents) can be running on the same set (or subset) of machines. If that's the case, Tomcat instances, and Grid Agents run on different ports for each grid. When multiple grids use the same machines they don't interfere with each other and can be operated simultaneously. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
