'db'=>array(
'connectionString' => 'mysql:host=localhost;dbname=test',
'emulatePrepare' => true,
'username' => 'root',
'autoConnect'=>false,
'password' => '123',
'charset' => 'utf8',
),

'cache'=>array(
'class'=>'system.caching.CDbCache',
'connectionID'=>'db',
//'autoCreateCacheTable'=>false,
//'cacheTableName'=>'yiicache',
),

CDbCache had already produced table('yiicache') in my database!

But When my Web application run :

Yii::app()->cache->set("persons",$persons,60);

It will make a mistake:

CDbConnection is inactive and cannot perform any DB operations.

I don't know Why?

Since he had already produced the table, represents CDbCache is normal!

Is really my database question?

No wonder, you disabled auto connect:

Thank you for your reply!

But I had already tried!

It still could not the normal operation!

I thought that is not this reason!
