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

　　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
　　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
　　127.0.0.1.6100 127.0.0.1.55228 49152 0 49152 0 TIME_WAIT
　　127.0.0.1.6100 127.0.0.1.55229 49152 0 49152 0 TIME_WAIT
　　127.0.0.1.6100 127.0.0.1.55230 49152 0 49152 0 TIME_WAIT
　　127.0.0.1.6100 127.0.0.1.55231 49152 0 49152 0 TIME_WAIT
　　127.0.0.1.6100 127.0.0.1.55232 49152 0 49152 0 TIME_WAIT
　　3) "sdtprocess" (Solaris), or "top" show that the listener process (tnslsnr) is using a large amount of cpu.

　　4) The 10g(iAS) $ORACLE_HOME/opmn/log on the same system shows the following repeating error in the ons logs:
　　04/10/01 13:30:43 [4] Local connection 0,127.0.0.1,6100 missing form factor
　　04/10/01 13:30:43 [4] Local connection 0,127.0.0.1,6100 missing form factor
　　04/10/01 13:30:43 [4] Local connection 0,127.0.0.1,6100 missing form factor
　　04/10/01 13:30:43 [4] Local connection 0,127.0.0.1,6100 missing form factor
　　04/10/01 13:30:43 [4] Local connection 0,127.0.0.1,6100 missing form factor
　　Changes
　　- Both 10g(iAS) and Oracle 10g(rdbms) are installed on the same system.
　　- Oracle 10g (non-RAC) is installed on a system with or without other Oracle installations.
　　Cause

　　The Oracle Notification Server (ONS) running in the 10g(iAS) home uses the ports defined in $ORACLE_HOME/opmn/conf/ons.config. The database listener, which is an ONS client, also utilizes the ONS ports>　　In non-RAC environments where Oracle 10g is the only Oracle product on the system, the existence of the ons.config may still cause a hang condition in the listener.
　　Solution
　　This issue is corrected in versions 10.2.0.3 and higher.
　　(or apply backport patch )
　　You may also use either of the following 2 workarounds to address this problem:
　　1)  In the 10g(rdbms) home, rename the $ORACLE_HOME/opmn/conf/ons.config file (so that the listener does not find or use it).
　　For example:
　　cd $ORACLE_HOME/opmn/conf
　　mv ons.config ons.config.orig
　　(then restart the listener)
　　- or -
　　2)  Explicitly disable the 10g TNS Listener from subscribing to the ONS.
　　Edit the active 10g  listener.ora file and add the parameter below:
　　SUBSCRIBE_FOR_NODE_DOWN_EVENT_=OFF
　　where  would be replaced with the actual listener name configured in the listener.ora file.
　　For example, if the listener name is LISTENER (default), the parameter would be:
　　SUBSCRIBE_FOR_NODE_DOWN_EVENT_LISTENER=OFF
　　(then restart the listener)
