思路一：关闭监听日志，删除已有日志
1、检查监听日志状态
- C:\Users\Administrator>lsnrctl
- LSNRCTL> status
- ...
- LISTENER 的 STATUS
- ------------------------
- 别名 LISTENER
- 版本 TNSLSNR for 64-bit Windows: Version 11.2.0.3.0 - Produ
- ction
- 启动日期 26-10月-2017 13:03:25
- 正常运行时间 0 天 0 小时 2 分 19 秒
- 跟踪级别 off
- 安全性 ON: Local OS Authentication
- SNMP OFF
- 监听程序参数文件 D:\app\Administrator\product\11.2.0\dbhome_1\network\a
- dmin\listener.ora
- 监听程序日志文件 D:\app\Administrator\diag\tnslsnr\WIN-database\listener\alert\log.xml
- ...
- 实例 "orcl", 状态 READY, 包含此服务的 1 个处理程序...
- 服务 "orclXDB" 包含 1 个实例。
- 实例 "orcl", 状态 READY, 包含此服务的 1 个处理程序...
- 命令执行成功
2、修改listener.ora，增加下方标红行
- # listener.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\listener.ora
- # Generated by Oracle configuration tools.
- INBOUND_CONNECT_TIMEOUT_LISTENER = 0
- SID_LIST_LISTENER =
- (SID_LIST =
- (SID_DESC =
- (SID_NAME = CLRExtProc)
- (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
- (PROGRAM = extproc)
- (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
- )
- (SID_DESC =
- (SID_NAME = CLRExtProc)
- (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
- (PROGRAM = extproc)
- (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
- )
- )
- LISTENER =
- (DESCRIPTION_LIST =
- (DESCRIPTION =
- (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-database)(PORT = 1521))
- (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
- )
- )
- ADR_BASE_LISTENER = D:\app\Administrator
- Admin_Restrictions_LISTENER = OFF
3、设置log_status off
CMD中执行lsnrctl
- LSNRCTL> set log_status off
- 正在连接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=WIN-database)(PORT=1521)
- ))
- TNS-12508: TNS: 监听程序无法解析给定的 COMMAND
- LSNRCTL> reload
- 正在连接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=WIN-database)(PORT=1521)
- ))
- 命令执行成功
- LSNRCTL> set log_status off
- 正在连接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=WIN-database)(PORT=1521)
- ))
- LISTENER 参数 "log_status" 设为 OFF
- 命令执行成功
- LSNRCTL>
4、删除listener.log
删除 D:\app\Administrator\diag\tnslsnr\WIN-database\listener\trace\下日志释放空间
5、参考MOS文章
TNS-12508 When Issuing Any SET Command For The Listener (文档 ID 238312.1)
思路二：脚本定期删除
采用批处理清理脚本+系统任务调度定期检查清理监听日志文件，避免文件达到4G
脚本如下:
- @echo off
- ::该脚本实现当监听日志文件大小达到一定大小(400M)时自动备份，防止达到4G时引发监听异常问题
- ::注意指定listener.log文件路径
- set ListenerLogFile=F:\app\TheOne\diag\tnslsnr\WIN-database\listener\trace\listener.log
- ::指定日志文件达到多大时进行删除，默认400M
- set FileSize=419430400
- set CurDate=%date:~0,4%%date:~5,2%%date:~8,2%
- set CurTime=%time%
- set CurDateTime=%CurDate%_%CurTime:~0,2%%CurTime:~3,2%%CurTime:~6,2%
- ::停止监听写日志
- lsnrctl set log_status off
- FOR /f "delims=" %%i in ("%ListenerLogFile%") do (
- IF %%~zi gtr %FileSize% (ECHO 正在执行备份。。。 && ren %ListenerLogFile% listener.log.%CurDateTime%) else (IF %%~zi lss %FileSize% (ECHO 不执行清理 ) ))
- ::开启监听写日志
- lsnrctl set log_status on
- ::重载监听日志
- lsnrctl reload
- ping -n 8 127.0.0.1 >null
