How to use Offline Navigable Map in Netbeans IDE with Java Swing

SeyitDec 16 2021

I am developing a program that will run on linux using java swing in netbeans.

I tried using the jxmapviewer library with open street map but I was only able to view the map online.

Since the system will not be connected to the internet, I need to view the map offline, I need to show the information I get from the gps on the map and I need to keep a record of this information.

How can I do it? Thank you for your help.

You want to use MySQL Router as the load balancer for the cluster.  If you are running a load balancer to get to the application that is fine but bot for InnoDb Cluster traffic.

Hello,

Putting MySQL Router on a dedicated server (or more) is OK, but I really don't understand the benetifs to put it on cluster nodes !

Maybe your loadbalancer doesn't close connections ? Like that it's difficult to answer. Check the connectio status and variables in MySQL and check the connections in the router.

Regards,

Place Router on the application nodes not on the InnoDB cluster nodes.  See https://dev.mysql.com/doc/mysql-router/8.0/en/

Hello,

I agree with all the answers. I still don't understand this statement:

"You want to use MySQL Router as the load balancer for the cluster."

Is MySQL Router a load balancer by itself? Then does the Router itself have HA capability?

Thanks,

MySQL Router will load balance the queries to innoDB Cluster or ReplciaSet.

In my test environment, I installed multiple mysqlrouter and start them. I'm testing if one of mysqlrouter process stop, can client connection be failed over to another mysqlrouter instance automatically. I tested with Keepalived. So far it wasn't successful. It looks like mysqlrouter is Single-Point-of-Failure.
