properti sumber data mysql terbaik untuk grails Tomcat jndi

AFAIK, Tomcat tidak ada hubungannya dengan mengelola koneksi database. Sejak Grails 2.3.6 , ini adalah properti sumber data default yang disarankan:

properties {
  //see http://grails.org/doc/latest/guide/conf.html#dataSource for documentation
   jmxEnabled = true
   initialSize = 5
   maxActive = 50
   minIdle = 5
   maxIdle = 25
   maxWait = 10000
   maxAge = 10 * 60000
   timeBetweenEvictionRunsMillis = 5000
   minEvictableIdleTimeMillis = 60000
   validationQuery = "SELECT 1"
   validationQueryTimeout = 3
   validationInterval = 15000
   testOnBorrow = true
   testWhileIdle = true
   testOnReturn = false
   jdbcInterceptors = "ConnectionState;StatementCache(max=200)"
   defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED
}
