OGG-01022 Unknown N bytes message received & OGG-01223 Connection reset by peer

最近查看OGG (12.2)的ggserr.log里出现了下面的信息,但是OGG进程还能正常工作, 相同时间段好几台DB ogg出现了相同的日志。

TIPs:

可以确认未信息包是从111.96.90.2 主机3615端口发送过来的,请求本地的7841端口,为本地OGG的replicate进程。 这样的错误通常是有网络端口扫描工具引起的,后期确认了该主机当时确是有安全扫描。 在tcperrs文件中检查了TCP错误行为,如果未在tcperr文件中定义错误,则默认行为是异常终止。Oracle 在MOS中描述了该错误。

[oracle@anbob1:/interface/ogg> rmsock f1000e007cd263b8 tcpcb
The socket 0xf1000e007cd26008 is being held by proccess 19661906 (replicat).

[oracle@anbob1:/interface/ogg> ps -ef|grep 19661906|grep -v grep
  oracle 19661906 24380914   0   Sep 09      -  5:52 /interface/ogg/replicat PARAMFILE /interface/ogg/dirprm/raccta01.prm REPORTFILE /interface/ogg/dirrpt/RACCTA01.rpt PROCESSID RACCTA01 USESUBDIRS
  oracle 21562930 19661906   0   Sep 09      -  0:13 oracleanbob1 (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))

Solution:

ORACLE还是非常的傲慢,当前的解决方法是安全扫描不应该扫描OGG的端口。从11.2.1.0.6开始只会写入ogg-1223的warning,但还是可以继续工作。但在之前的版本可能需要重启MGR进程。
