转： 清理监听日志处理的方法 以及监听安装设定

 1：首先停止监听服务进程（tnslsnr）记录日志。 lsnrctl  set log_status off; 
2：将监听日志文件（listener.log）复制一份，以listener.log.yyyymmdd格式命名 cp listener.log listener.log.20150622
3、将监听日志文件（listener.log）清空。清空文件的方法有很多 cat /dev/null > listener.log
4：开启监听服务进程（tnslsnr）记录日志 lsnrctl set log_status on;

对于这种listener.log增长非常迅速的系统，可以关闭监听日志lsnrctl  set log_status off，不让监听写日志到文件。也可以写个job定期清理。

监听安全设定：


SECURE_REGISTER_dtaruat= (IPC)
SECURE_CONTROL_listener=(TCPS,IPC)
ADMIN_RESTRICTIONS_listener= ON
DIAG_ADR_ENABLED_listener= OFF

方案2：

2. 查看监听日志大小

不管在Windows环境下，或者Linux环境下均可根据上文中日志位置或者根据日志文件名查找监听日志文件大小。

3. 日志文件的备份和重命名

Oracle监听器在运行时不允许对日志文件做删除，重命名操作，可以设置日志状态为ON或OFF来实现启用或关闭日志。

在日志文件过大的情况下，可使用不停止监听的情况下对日志文件重命名以实现备份。

a) Windows环境下

C:> cd D:oracleproduct10.2.0db_1NETWORKlog --切换到监听器日志文件所在目录

D:oracleproduct10.2.0db_1NETWORKlog> lsnrctl set log_status off --暂停或脱机记录日志文件

D:oracleproduct10.2.0db_1NETWORKlog> rename listener.log listener.old150424 --重命名日志文件，一般加上日期

D:oracleproduct10.2.0db_1NETWORKlog> lsnrctl set log_status on --联机监听器日志文件，会自动重新创建一个新的日志文件

b) Unix/Linux环境下

LSNRCTL>
LSNRCTL>set current_listener db
LSNRCTL>set log_status off

#mv listener.log listener.old150424

$lsnrctl set log_status on

###ref:

1.bash for linux
ksh for unix

2.bash == and =
ksh =

3.function:

bash:

function :
bash函数有三种写法：
[plain] view plain copy
function func1 () { 
echo "This is an example of bash function 1" 
} 

function func2 { 
echo "This is an example of bash function 2" 
} 


func3 () { 
echo "This is an example of bash function 3" 
}

但是，第一种写法在有的 bash版本下会报错。

ksh:
http://blog.csdn.net/shangboerds/article/details/48711561

#!/bin/ksh 
################### 函数必须先定义后使用 

# 定义函数方式 1: ksh 语法 
function fun_test1 { 
print "This is function fun_test1."; 
} 

# 定义函数方式 2: POSIX 语法 
fun_test2 (){ 
print "This is function fun_test2."; 
} 

# 参数 
function fun_test3 { 
print "Enter function $0"; # $0 表示函数名 
print "The first parameter is $1"; # $1 引用第一个参数 
print "The second parameter is $2"; # $2 引用第二个参数 
print "This function has $# parameters"; # $# 表示参数的个数 
print "You are calling $0 $*"; # $* 是个数组，存储所有的参数 
print "You are calling $0 $@"; # $@ 是个数组，存储所有的参数 
}

4.bash ksh function 必须在最开头定义，不然function 找不到sqlplus 执行路径：

ORACLE_HOME=/datalv03/10205/10g
PATH=$ORACLE_HOME/bin:$PATH

5.测试环境，创建0_ksh.sh， 按照步骤从上往下测试，注意回退（##复现问题）和前进，因此需要2倍的代码量。
0_ksh.sh

6  test 语法 :

准确来说是适用对象不同：
-eq 和 = 都可以用来条件测试进行判断两个操作对象是否相同，但是有如下区别：
-eq 适用于整数数字，不能进行字符串的条件测试
= 既适用于数字，又适用于字符串。
我做了下测试：

$ [ 1 -eq 1 ] && echo "ok"
ok
$ [ 1 = 1 ] && echo "ok"
ok
$ [ "a" -eq "a" ] && echo "ok"
sh: [: a: 需要整数表达式
$ [ "a" = "a" ] && echo "ok"
ok
楼主想进一步了解的话可以搜索下"shell 条件测试"

-c FILE
FILE exists and is character special
-d FILE
FILE exists and is a directory
-e FILE
FILE exists
-f FILE
FILE exists and is a regular file
-g FILE
FILE exists and is set-group-ID
-G FILE
FILE exists and is owned by the effective group ID
-h FILE
FILE exists and is a symbolic link (same as -L)
-k FILE
FILE exists and has its sticky bit set
-L FILE
FILE exists and is a symbolic link (same as -h)
-O FILE
FILE exists and is owned by the effective user ID
-p FILE
FILE exists and is a named pipe
-r FILE
FILE exists and read permission is granted
-s FILE
FILE exists and has a size greater than zero
-S FILE

-t FD file descriptor FD is opened on a terminal
-u FILE
FILE exists and its set-user-ID bit is set
-w FILE
FILE exists and write permission is granted
-x FILE
