1、amoeba配置文件

1.1 dbservers.xml

<?xml version="1.0" encoding="gbk"?>

        <!-- 
            Each dbServer needs to be configured into a Pool,
            If you need to configure multiple dbServer with load balancing that can be simplified by the following configuration:
             add attribute with name virtual = "true" in dbServer, but the configuration does not allow the element with name factoryConfig
             such as \'multiPool\' dbServer

1.3配置JVM

找到JVM.properties,并找到下面的参数

JVM_OPTIONS="-server -Xms256m -Xmx1024m -Xss256k -XX:PermSize=16m -XX:MaxPermSize=96m"
-Xms256m  :jvm初始化内存大小
-Xmx1024m  :jvm最大的内存空间
-Xss    :单个线程大小,在amoeba中最小为217
