2009.3.20，DB的instance被人停了，我先上去运行lsnrctl status，发现某个instance被停，于是再把lsnrctl stop掉，再startup instance，再用lsnrctl start时出错：

Applies to:
Oracle Net Services - Version: 10.1.0.0 to 10.2.0.2
This problem can occur on any platform.
Symptoms
Unable to start an Oracle10g R1 (or R2) TNS Listener on Unix:
For example:
$ lsnrctl start
LSNRCTL for HPUX: Version 10.1.0.4.0 - Production on 01-JUL-2005 10:16:59
Copyright (c) 1991, 2004, Oracle. All rights reserved.
Starting /db02/product/10.1/bin/tnslsnr: please wait...
TNS-12537: TNS:connection closed
TNS-12560: TNS:proto adapter error
TNS-00507: Connection closed
HPUX Error: 29: Illegal seek
Changes
Verify the user attempting to start the TNS Listener process has read permissions on the /etc/hosts file, and that this file contains the localhost entry:
127.0.0.1 localhost.localdomain localhost
192.168.2.20 prfinders.us.oracle.com prfinders .
Cause
TNS Listener fails while attempting to initiate subscription to ONS node down event.
Level 16 TNS Listener trace shows the last action:
...
[01-JUL-2005 10:16:59:727] nsglonsinit: Initiated subscription for node down event
...
Same symptoms and corrective action found in Bug 4227455 OCS_MAIN_SOLARIS_050304 - UNABLE TO START THE SECOND LISTENER of if OS User is unable to read the /etc/hosts file.
Solution
To implement the solution, please execute the following steps:
1. Explicitly disable the 10g TNS Listener's subscrition to ONS by editing the listener.ora file and add the parameter below:
SUBSCRIBE_FOR_NODE_DOWN_EVENT_<listener_name>=OFF
where <listener_name> 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
- Save the listener.ora file
2. Start the TNS Listener from a new LSNRCTL prompt:
lsnrctl <return>
LSNRCTL> start
