tcp连接过多导致监听TNS-12532 TNS-12560 TNS-00502错误

数据库监听启动报TNS-12532、TNS-12560、TNS-00502错误,无法正常启动

尝试重建监听提示端口占用,对于这种情况,第一反应可能是数据库服务器的一些tcp链接异常.通过netstat -nao查看发现8080端口的应用占用TCP链接太多

820
通过分析发现该tcp链接已经达到7w多个,怀疑是该问题导致监听异常,重启应用释放这些连接之后,数据库监听恢复正常.

监听报TNS-12541 TNS-12560 TNS-00511错误

发表于 2024 年 9 月 5 日 由 惜分飞

有客户运行在win平台上的oracle 11.2.0.1,监听无法正常工作,使用status查看,卡很长时间然后出现如下TNS-12541 TNS-12560 TNS-00511 64-bit Windows Error: 2: No such file or directory错误

LSNRCTL> status

根据以往经验,监听服务本身启动成功,运行status hang很久,有可能和监听日志有关系,通过查看确认监听日志达到4G,关闭服务,重命名监听日志,再次启动监听,状态正常
listener

关于win平台监听超过4G,引起监听hang住的文章:windows平台listener.log超过4G导致监听异常

TNS-12518: TNS:listener could not hand off client connection

发表于 2024 年 3 月 12 日 由 惜分飞

客户反馈业务经常性出现数据库连接异常,通过工具访问ORACLE进程报ORA-12170
ORA-12170

通过分析发现lsnrctl status几乎hang住，tnsping延迟特别大
tnsping-slow
进一步分析监听日志发现TNS-12518: TNS:listener could not hand off client connection错误

12-MAR-2024 15:34:50 * (CONNECT_DATA=(CID=(PROGRAM=JDBC Thin Client)
(HOST=__jdbc__)(USER=Administrator))(SERVICE_NAME=ilas)) * (ADDRESS=(PROTOCOL=tcp)
(HOST=ip)(PORT=52854)) * establish * ilas * 12518
TNS-12518: TNS:listener could not hand off client connection
 TNS-12547: TNS:lost contact
  TNS-12560: TNS:protocol adapter error
   TNS-00517: Lost contact
    Linux Error: 32: Broken pipe

根据经验和Troubleshooting Guide for TNS-12518 TNS listener could not hand off client connection描述,检查监听文件配置

[oracle@xff admin]$ cat listener.ora
# listener.ora Network Configuration File:/home/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = /home/u01/app/oracle/product/11.2.0/dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:/home/u01/app/oracle/product/11.2.0/dbhome_1/bin/oraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = IP)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /home/u01/app/oracle

根据经验和客户的业务进行分析,确认他们不会使用 external procedures方式访问数据库,直接修改监听配置

[oracle@xff admin]$ cat listener.ora
# listener.ora Network Configuration File:/home/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = xff)
      (ORACLE_HOME = /home/u01/app/oracle/product/11.2.0/dbhome_1)
      (GLOBAL_DBNAME = xff)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = IP)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /home/u01/app/oracle

然后reload配置,再使用lsnrctl status查看结果秒出,tnsping也非常快

让客户测试应用也恢复正常,一切ok,问题在最小修改的情况下解决,和最初供应商建议的重装系统,双机,数据库等解决方案大大简化
