Hi!

Im having some extra data on each user that i'd like to save when the server restarts. The problem is that the I can't find any place to save the data at.

First i hoped that the internal event "userLost" would be fired when the server stopped but that didnt happen.

Then I tried destoy() in my zone extension like this.

Code: Select all

	public void destroy() {
		
		System.out.println("Kicking all users in zone");
		@SuppressWarnings("unchecked")
		LinkedList<User> allUsers = this.zone.getAllUsersInZone();
		
		//try to logout all users
		for(User u:allUsers){
			System.out.println("Kicking user " + u.getName());
			this.server.logoutUser(u, false, true);
		}
		
		System.out.println("Zone destoyed");
	}

it only traces

2009-jan-26 17:59:34 it.gotoandplay.smartfoxserver.extensions.AdminExtension sendHaltSignal
INFO: Server Halt was requested by administrator.

Halting Server ...

Kicking all users in zone
Zone destoyed

Is there any other place that I can handle a logut nice and save all my data to a mysql-database.

This is a problem right now since all users online will lose their stats if we restart the database.

There are sone exceptions thrown after "Zone destoyed" but i think thats a trailproblem from users not being kicked and then our Ping-module tries to kick it again since it havn't been cleaned up correctly.
Anyway it looks like this. Might be to any help:

Thanks in advance

b.t.w we are using SFS Pro 1.6.3

just writing to get the notify when anyone writes something

This would be useful for me as well. If anyone is willing to share a solution or workaround for this it would be greatly appreciated!

Right now I have the server periodically save certain information to XML files. The data isn't important enough to constantly save to the DB, but it's important enough that I would like to recover it if the server suddenly crashes.

It would be great if right before the server kicks the bucket or if I need to manually restart it, it could save certain information to XML files.

right now I have solved it with a costy workaround.

First I lock the server so that no-one can log in. Then I kick all users that are not in a game and save all their data.
Then I kick all users that leave a game under a period of 15 minutes.
Then after 15 minutes I kick all the users that haven't left the games.

Now the server is empty and i can save all other info and then restart the server manually.
