数据库在运行了5-6个小时之后,会出现连接异常,用netmgr测试出现ora-12560 错误,增大了process 和sessions之后运行时间会延长到8个小时,之后继续出现12560错误
请教高手,这个问题应该怎么解决?

ORA-12560: TNS:protocol adapter error
Cause: A generic protocol adapter error occurred.
Action: Check addresses used for proper protocol specification. Before reporting this error, look at the error stack and check for lower level transport errors. For further details, turn on tracing and reexecute the operation. Turn off tracing when the operation is complete.
和processes、session好像没关系
