tomcat启动时报错,非常紧急,在线等待
在AIX系统下启动tomcat,结果总是报错,是用数据源连接db2数据库
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory ([IBM][CLI Driver] SQL30081N A communication error has been detected. Communication protocol being used: "TCP/IP". Communication API being used: "SOCKETS". Location where the error was detected: "". Communication function detecting the error: "connect". Protocol specific error code(s): "78", "*", "*". SQLSTATE=08001
)
请问这是什么原因造成的?
