系统环境硬件平台 & 操作

IBM 570

操作系统版本 AIX 5.3

物理内存 32G

Oracle 产品及版本 10.2.0.5 RAC

业务类型 OLTP

背景概述

交易系统在xx月xx 日，节点二VIP异常下线导致节点二数据库服务失

效。接到请求后，第一时间进行连线处理。故障发生在凌晨 3点，而且

AIX（errpt）、Oracle DB（alert.log ）、CRS （crsd.log 、ocssd.log、vip.log、

coredump ）等均没有留下太多有效信息，情况非常复杂。

问题详细诊断及分析

一、检查errpt日志：

节点二VIP异常下线时，节点二上无报错产生。

二、检查CRS日志：

节点一：

— 说明：节点一上仅有一行信息反映出故障期间节点一上CRS曾经执行过命令。

节点二：

— 说明：节点二是故障节点，上面信息反映出，由于VIP检测异常导致节点二上VIP被强

制OFFLINE，同时CRS将基于VIP 资源的监听和数据库服务也进行了OFFLINE操作。

三、分析CRS状态：

由于故障期间客户很好的保留了现场环境，因此我们得以现场分析到CRS

状态。

Name Type Target State Host

------------------------------------------------------------

ora.xxxxdb.db application ONLINE ONLINE xxdb01np5

ora....sdb1.cs application ONLINE OFFLINE

ora....db1.srv application ONLINE ONLINE xxdb01np5

ora....db2.srv application ONLINE ONLINE xxxxdb02

ora....b1.inst application ONLINE ONLINE xxdb01np5

ora....b2.inst application ONLINE ONLINE xxxxdb02

ora....P5.lsnr application ONLINE OFFLINE

ora....np5.gsd application ONLINE ONLINE xxxxdb02

ora....np5.ons application ONLINE ONLINE xxxxdb02

ora....np5.vip application ONLINE ONLINE xxdb01np5

— 说明：故障期间，节点二上的数据库（实例）资源仍然在运行，Nodeapp资源正常，

唯一被OFFLINE的是一个Service和listener 资源。但是我们注意到节点二上VIP 资源

已经被节点一接管过去。这说明，节点二的VIP（xxx.xxx.xxx.4 ）在排查问题的时候是

没问题的。

四、分析数据库告警日志

— 说明：故障期间，节点二上数据库的Service被OFFLINE，这一点正常。但随后CRS

将连接到节点二上的所有客户端连接都强行Kill掉了。该问题和Oracle Bug 6955040有

关。

五、分析RACGVIP

由于问题原因定位到 VIP资源异常上，而VIP切换到节点一上是正常的，

因此极有可能是由于VIP检查的时候出现异常导致CRS 将VIP OFFLINE。由于

Oracle CRS在进行VIP检测的时候是通过RACGVIP这个 SHELL脚本实现功能

的，因此我们分析和测试了RACGVIP脚本。

我们注意到其中一段脚本，如下：

#Check the status of the interface thro' pinging gateway

if[ -n "$DEFAULTGW" ]

then

_RET=1

#get base IP address of the interface

tmpIP=`$LSATTR -El ${_IF} -a netaddr | $AWK '{print $2}'`

#get RX packets numbers

_O1=`$NETSTAT -n -I $_IF | $AWK "{ if (/^$_IF/) {print \\$5;exit}}"`

x=$CHECK_TIMES

while [ $x -gt 0 ]

if [ -n "$tmpIP" ]

then

$PING -S $tmpIP $PING_TIMEOUT $DEFAULTGW > /dev/null 2>&1

else

$PING $PING_TIMEOUT $DEFAULTGW > /dev/null 2>&1

_O2=`$NETSTAT -n -I $_IF | $AWK "{ if (/^$_IF/) {print \\$5;exit}}"`

if [ "$_O1" != "$_O2" ]

then

# RX packets numbers changed

_RET=0

break

$SLEEP 1

x=`$EXPR $x - 1`

done

if [ $_RET -ne 0 ]

then

logx "checkIf: RX packets checked if=$_IF failed"

else

logx "checkIf: RX packets checked if=$_IF OK"

else

logx "checkIf: Default gateway is not defined(host=$HOSTNAME)"

if [ $FAIL_WHEN_DEFAULTGW_NO_FOUND -eq 1 ]

then

_RET=1

else

_RET=0

— 说明：这段脚本说明，CRS在做VIP check的时候机制如下，定期向缺省网关（Default

Gateway）发包，如果发包前后检测到网卡上有包流量（output值前后不一样）则说

明检测网络正常，VIP check通过。发包的操作通过AIX 命令执行，还原所有变量后的

命令如下

— ping –S xxx.xxx.xxx.2 –c 1–w 1 xxx.xxx.xxx.254

— 参数含义如下：

-S hostname/IP addr

Uses the IP address as the source addressin outgoing ping packets.

-c Count

Specifies the number of echo requests, asindicated by the Count

variable, to be sent (and received).

-w timeout

This option works only with the -c option.It causes ping to wait

for a maximum of 'timeout' seconds for areply (after sending the

last packet).

— PING_TIMEOUT参数控制了-c 和-w的值，RACGVIP 脚本中设置如下：

# timeout of ping in number of loops

PING_TIMEOUT=" -c 1 -w 1"

— 我们检查了10.2.0.3版本下的设置，发现在10.2.0.3版本下，PING_TIMEOUT参数设置

为如下值：

# timeout of ping in number of loops

PING_TIMEOUT=" -c 1 -w 3"

— 当前PING_TIMEOUT的设置意味着如果在pingdefault gateway 的1秒内没有成功向

外发送出一个包，那么CRS会经过一次SLEEP后再次尝试ping操作，如果还是没有成

功，CRS即宣布网络异常，VIP OFFLINE。

结论

Oracle 10.2.0.5在RACGVIP脚本上的细微改变说明，Oracle认为10.2.0.5版本

下对网络性能及稳定性更高了。但是将PING_TIMEOUT 由1秒更改为3秒，会大

大增加CRS 的敏感度，使得细微的网络异常即会造成CRS 中的 VIP检测失败。

根据上述分析，我们认为节点二故障原因如下：

1、升级到10.2.0.5后，CRS 对网络延时更加敏感

2、在4月29 日凌晨3点故障期间，网络出现了及其短暂的延时导致VIP检测

失败，CRS 将VIP以及依赖于VIP的资源OFFLINE。

3、 CRS 在OFFLINE数据库服务的时候命中Bug6955040造成客户端连接被

全部杀光。

故障重现

我方在生产环境模拟了这一段异常情况：

步骤流程

1 打开CRS VIPdebug

节点二上找出VIP（xxx.xxx.xxx.4 ）使用的网络设备（en10）

以及对应的ServiceIP（xxx.xxx.xxx.2 ）

3 交换机上找出对应的端口

4 Block该端口一小段时间

5 观察CRS 和数据库日志

我方我们观察到其中 CRS 日志和数据库日志信息和故障期间完全一致，这

充分证明了前面的判断。

同时，VIP的debug 信息显示如下内容，我们可以从中清晰的看到，由于

网络问题导致发包失败后，CRS 立即将VIP置于 OFFLINE状态：
