MySQL
● You are going to run the database in a remote server.
● How to connect:○ ssh -A -fNg -L <localport>:localhost:3306
○ mysql -h localhost -u<istid> --protocol=TCP -P <localport> -p<dbpass> <istid>_fenix -A
MySQL
● Edit fenix-framework.properties:○ dbAlias=//localhost:<localport>/<istid>_fenix?
useUnicode=true&characterEncoding=utf8&clobCha
racterEncoding=utf8&zeroDateTimeBehavior=convertToNull
○ dbUsername=<istid>○ dbPassword=<dbpass>
So, how do you change your marks?
