[B]网络不稳定的时候,会出现会话中断引起的锁无法释放问题。因为UNIX缺省的TCP/IDLE参数是4个小时,由于网络问题引起的中断会话要4个小时后才会被PMON清理、释放锁。 [/B]
Where do you get the information that the default TCP "idle" time is 4 hours? What parameter are you talking about? Not sure what OS you have access to. In Solaris, type ndd /dev/tcp \? to get a list of the parameters and ndd /dev/tcp [the_parameter] to get its value. If you're talking about tcp_close_wait_interval, the default is 240,000 ms or 4 minutes, not 4 hours.
PMON takes 4 hours to clean up dead sessions? How do you know it takes that long?
