为你的Listener加个password

原创 Linux操作系统 作者:oracle_ace 时间:2007-12-17 10:09:24 0 删除 编辑

一般我们都是可以给所属的listener加一个密码以防止远程tns connect来关掉我们的listener
步骤是这样的:
$ lsnrctl

LSNRCTL for IBM/AIX RISC System/6000: Version 9.2.0.6.0 - Production on 26-SEP-2007 19:49:08

Copyright (c) 1991, 2002, Oracle Corporation.  All rights reserved.

Welcome to LSNRCTL, type "help" for information.

LSNRCTL> set current_listener listener
Current Listener is listener
LSNRCTL> change_password
Old password:
New password:
Reenter new password:
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC)))
Password changed for listener
The command completed successfully
LSNRCTL> set password
Password:
The command completed successfully
LSNRCTL> save_config
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC)))
Saved LISTENER configuration parameters.
Listener Parameter File   /opt/oracle/product/9.2.0.1/network/admin/listener.ora
Old Parameter File   /opt/oracle/product/9.2.0.1/network/admin/listener.bak
The command completed successfully
LSNRCTL> quit

这个时候我们采用普通的暂停Listener stop的命令会发现,已经停不掉Listener了
$ lsnrctl stop

LSNRCTL for IBM/AIX RISC System/6000: Version 9.2.0.6.0 - Production on 26-SEP-2007 19:50:56

Copyright (c) 1991, 2002, Oracle Corporation.  All rights reserved.

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC)))
TNS-01169: The listener has not recognized the password

这个时候我们再来观察一下我们的Listener.ora文件:
多出了这么一行:
#----ADDED BY TNSLSNR 26-SEP-2007 19:49:41---
PASSWORDS_LISTENER = 300200BB8EFECB93
#---------------------------------------------------------------------


此时如果我们想停止/启动Listener就得通过在本地运行:
$ lsnrctl

Welcome to LSNRCTL, type "help" for information.
