Hello Erel!
I'm using two Databases: one MySQL 4.0 Instance and one MariaDB 10.0 Instance, installed on different server machines.
The MariaDB Instance is the Web Server Database and MySQL 4.0 is my old VB6 application's RDBMS.
Testing whole system, I decided to connect web socket server to the old database in order to have faster response time rather than my previous case that I was sending messages from the web server to socket server which was forwarding the messages to my old VB6 application for executing several Database Jobs.
I've already built the connection pooling and I think I have much better response than my previous approach.
Great B4X tools!!!
