最近接手一个windows 下的oracle ，发现监听日志已经到了1.5G。
以前都是在aix，linux上干活 ，突然倒了windows反而不太习惯。
下面记录一下清理过程：
D:\oracle\product\102\NETWORK\log>echo >listener.log
The process cannot access the file because it is being used by another process.
D:\oracle\product\102\NETWORK\log>copy /y sqlnet.log listener.log
1 file(s) copied.
D:\oracle\product\102\NETWORK\log>dir
Volume in drive C is System
Volume Serial Number is B8E0-1DBE
Directory of D:\oracle\product\102\NETWORK\log
09/20/2011 02:42 PM <DIR> .
09/20/2011 02:42 PM <DIR> ..
09/20/2011 03:10 PM 541 listener.log
09/20/2011 03:09 PM 13 sqlnet.log

D:\Liangwei>help copy
Copies one or more files to another location.
COPY [/D] [/V] [/N] [/Y | /-Y] [/Z] [/A | /B ] source [/A | /B]
[+ source [/A | /B] [+ ...]] [destination [/A | /B]]
source Specifies the file or files to be copied.
/A Indicates an ASCII text file.
/B Indicates a binary file.
/D Allow the destination file to be created decrypted
destination Specifies the directory and/or filename for the new file(s).
/V Verifies that new files are written correctly.
/N Uses short filename, if available, when copying a file with a
non-8dot3 name.
/Y Suppresses prompting to confirm you want to overwrite an
existing destination file. 覆盖文件不提示
/-Y Causes prompting to confirm you want to overwrite an
existing destination file. 覆盖文件提示
/Z Copies networked files in restartable mode.
The switch /Y may be preset in the COPYCMD environment variable.
This may be overridden with /-Y on the command line. Default is
to prompt on overwrites unless COPY command is being executed from
within a batch script.
To append files, specify a single file for destination, but multiple files
for source (using wildcards or file1+file2+file3 format).
