Hi,
I am trying to use Openfire with MySql 8.0. I have started the configuration on http://localhost:9090/setup/setup-datasource-standard.jsp and came up to database settings. here I am giving the database connection settings.
jdbc:mysql://localhost:3306/chatdb?rewriteBatchedStatements=true
user name, password, min/max connections and timeout.
But when clicked on continue, it throws an error. The error is captured in the logs.
Some search on internet says that the property ‘query_cache_size’ is removed in 8.0 verions of mysql. But is there any way around it?
The exception is as below:
