DB2 server 在链接数增多的情况下 就会报错 如下：
04:47:24 com.mchange.v2.c3p0.impl.NewPooledConnection@5850b563 invalidated by Exception.
com.ibm.db2.jcc.am.DisconnectNonTransientConnectionException: [jcc][t4][2030][11211][3.61.86] A communication error occurred during operations on the connection's underlying socket, socket input stream,

但是 ： dbm 的配置信息中的设置是没有限制的：
Max number of coordinating agents (MAX_COORDAGENTS) = AUTOMATIC(250)
Max number of client connections (MAX_CONNECTIONS) = AUTOMATIC(1000)
查看其他报错帖子 有可能是：TCP/IP服务名称和 /etc/services中定义的db2服务名称不一致,导致连接不上
check 本地tcp/ip 设置和 /etc/services 文件的配置 ：
TCP/IP Service name (SVCENAME) = db2c_db2inst1
db2c_db2inst1 50000/tcp
DB2_HADR_1 55001/tcp
DB2_HADR_2 55002/tcp
DB2_db2inst1 60000/tcp
DB2_db2inst1_1 60001/tcp
DB2_db2inst1_2 60002/tcp
DB2_db2inst1_END 60003/tcp
并没有不一致的情况
那位高手遇到过这类情况 请指点下哦
