oprocd进程fatal与non fatal模式切换

下面来源与MOS文档：

Troubleshooting 10g and 11.1 Clusterware Reboots (Doc ID 265769.1)

下面是sun的案例

Edit the init.cssd file from the location in step 1, change the OPROCD startup line to a non-fatal startup:

Sun Example:

# in fatal mode we always will start OPROCD FATAL

if [ $OPROCD_EXISTS ]; then

$OPROCD start -t $OPROCD_DEFAULT_TIMEOUT -m $OPROCD_DEFAULT_MARGIN

$OPROCD check -t $OPROCD_CHECK_TIMEOUT 2>$NULL

fi

Change this to:

# in fatal mode we always will start OPROCD FATAL

if [ $OPROCD_EXISTS ]; then

$OPROCD startInstall -t $OPROCD_DEFAULT_TIMEOUT -m $OPROCD_DEFAULT_MARGIN

$OPROCD check -t $OPROCD_CHECK_TIMEOUT 2>$NULL

fi

You could also combine this method with the ‘tracing system calls’ method for more debugging.

下面是在我的linux上面测试

[root@cisser1 oprocd]# oprocd help

run [ -t | -m | -g | -f | -e] foreground startup

-t <timeout> timeout in ms

-m <margin> timout margin in ms

-e <epsilon> clock skew epsilon in ms

-g <groupName> group name to enable fatal

-f fatal startup

start [-t | -m | -e] starts the daemon

-t <timeout> timeout in ms

-m <margin> timout margin in ms

-e <epsilon> clock skew epsilon in ms

startInstall [ -t | -m | -g | – e] start process in install mode

-t <timeout> timeout in ms

-m <margin> timout margin in ms

-e <epsilon> clock skew epsilon in ms

-g <groupName> group name to enable fatal

enableFatal [ -t ] force install mode process to fatal

-t <timeout> timeout for response in ms

stop [ -t ] stops running daemon

-t <timeout> timeout for response in ms

check [ -t ] checks status of daemon

-t <timeout> timeout for response in ms

help this help information

-? same as help above

下面看看init.cssd日志

使用startInstall模式启动

# Backup the oprocd last gasp files

if [ -f $OPROCDLGL ] ; then

FILENAME=$OPROCDLGL.$UNIQUEDATE

$MVF $OPROCDLGL "$FILENAME"

fi

# Run oprocd synchronously and look for its status code

cd $OPROCDIR

# startup the some diagnostic collection scripts if any

StartDiagCollect;

$OPROCD startInstall -t $OPROCD_DEFAULT_TIMEOUT -m $OPROCD_DEFAULT_MARGIN \

$OPROCD_DEFAULT_HISTOGRAM $FATALARG

RC=$?

# shutdown diagnostic collection

StopDiagCollect;

看看日志显示

[root@cisser1 oprocd]# /etc/init.d/init.crs stop

Shutting down Oracle Cluster Ready Services (CRS):

Mar 27 09:33:33.060 | ERR | failed to connect to daemon, errno(111)

Stopping resources. This could take several minutes.

Error while stopping resources. Possible cause: CRSD is down.

Shutdown has begun. The daemons should exit soon.

[root@cisser1 oprocd]# /etc/init.d/init.crs start

Startup will be queued to init within 30 seconds.

没有生产任何的日志。

[root@cisser1 oprocd]# ps -ef|grep init

root 1 0 0 09:36 ? 00:00:01 init [5]

root 3242 1 0 09:37 ? 00:00:00 /bin/sh /etc/init.d/init.evmd run

root 3243 1 0 09:37 ? 00:00:00 /bin/sh /etc/init.d/init.cssd fatal

root 3252 1 0 09:37 ? 00:00:00 /bin/sh /etc/init.d/init.crsd run

root 4136 3243 0 09:37 ? 00:00:00 /bin/sh /etc/init.d/init.cssd daemon

root 22547 21136 0 09:39 pts/0 00:00:00 grep init

[root@cisser1 oprocd]# ps -ef|grep oproc

root 23775 21136 0 09:39 pts/0 00:00:00 grep oproc

这里没有看到oprocd进程，也没有看到生成任何的日志。

取消-f选项

# startup the some diagnostic collection scripts if any

StartDiagCollect;

$OPROCD startInstall -t $OPROCD_DEFAULT_TIMEOUT -m $OPROCD_DEFAULT_MARGIN \

$OPROCD_DEFAULT_HISTOGRAM

#$OPROCD_DEFAULT_HISTOGRAM $FATALARG

RC=$?

这里直接重启的主机

[root@cisser1 oprocd]# ls -lrt

这里看到生成了日志文件，并且日志文件里面也有内容，但是日志里面没有fatal与noe fatal的标示符。

下面是默认情况

# startup the some diagnostic collection scripts if any

StartDiagCollect;

$OPROCD run -t $OPROCD_DEFAULT_TIMEOUT -m $OPROCD_DEFAULT_MARGIN \

$OPROCD_DEFAULT_HISTOGRAM $FATALARG

RC=$?
