tomcat没访问几次就歇菜了~

没有连接池
tomcat也没有设置任何东西，应该我的程序有问题··谁能帮忙看看，顺便解决下，谢谢~~
··还有数据库如果用oracle，当V$session这张表 达到150左右就会报错··是什么原因呢
[解决办法]
session有个disconnect方法吧
[解决办法]
报的是数据库连接池达到最大数了吧。你应该加一个数据库连接池。分区进行设置。
<property name="idleConnectionTestPeriod" value="15" />
<property name="idleMaxAge" value="10" />
<property name="maxConnectionsPerPartition" value="10" />
<property name="minConnectionsPerPartition" value="5" />
<property name="partitionCount" value="3" />
<property name="acquireIncrement" value="5" />
