oprocd进程fatal与non fatal模式切换

RAC huangtingzhong 发布于 2015-03-26 23:22 抢沙发

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

usage:  oprocd [start | startInstall | stop | check | enableFatal| 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     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

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 $FATALARG
    RC=$?

这里明确的给出了是在fatal模式。
