linux oracle10.2.0.1 lsnrctl无法启动

故障现象：lsnrctl stat后即无任何反应,而SQLPLUS正常：

[oracle@wlserver3 ~]$ lsnrctl stat

尝试ps -ef|grep lsnrctl后kill -9 杀进程,但杀后重启时也碰到同样问题

尝试ps -ef|grep lsnr（注意和上述命令的区别少了ctl）后kill -9 杀进程,后重启成功

[root@wlserver3 admin]# ps -ef|grep lsnr

补充:处理过程中看到过一个10.2.0.1环境下的BUG,也一并修复掉了

10g Listener: High CPU Utilization - Listener May Hang [ID 284602.1]

Symptoms 拥有帝国一切，皆有可能。欢迎访问phome.net
1) If the listener is hanging, a sqlnet trace (level 16) will show that the last operation was a fork.

[000068 28-SEP-2004 14:16:17:398] sntpcall: entry
[000068 28-SEP-2004 14:16:17:401] sntpcall: detaching from parent with additional fork 68 bytes to NS buffer

2) netstat -na reports numerous (maybe thousands) of sockets associated with port 6100 in a TIME_WAIT status

3) "sdtprocess" (Solaris), or "top" show that the listener process (tnslsnr) is using a large amount of cpu.
