cakephp is not able to connect to database

[Kpod]

I am a cakephp newbie and I tried to setup my connection to mysql. I had it worked before but after I changed my mysql database name, it won't connect anymore even thought I changed the database name in database.php inside the config folder. Do I have to run the cakephp console again?? \[code\]Your tmp directory is writable.The FileEngine is being used for caching. To change the config edit APP/config/core.phpYour database configuration file is present.Cake is NOT able to connect to the databa\[/code\]Above is the message shown. Any ideas what I have to do? Thanks a lot!
