hacmp oracle monitor

这2天研究hacmp对oracle的监控，吃尽苦头了。。。

google遍网上每个旮旯头，没见到一个热心提供监控脚本的老大，我虽然自己能写，但是实在不知道hacmp的口味到底如何，IBM的文档里连个范例或者脚本的规范都没有，甚至连日志中都不说到底哪里出错了，导致监控失灵。。。唉，郁闷得我心火窜了三尺高

现在终于苦尽甘来，把这个折磨我许久的问题搞定了。

首先，为了避免oracle的listener和主进程出问题时互相干扰，造成不必要的重启。将对Listener和oracle主进程的监控分开，分别是ListenerMonitor和OraMonitor

Listener的monitor就偷懒不写脚本了，直接用hacmp的application process monitor的功能，采用进程来监控。具体的配置如下：

                                                        [Entry Fields]
* Monitor Name                                        ListenerMonitor
  Application Server(s) to Monitor                    oracle                                                                     +
* Monitor Mode                                       [Long-running monitoring]                                                   +
* Processes to Monitor                               [tnslsnr]
* Process Owner                                      [oracle]
  Instance Count                                     [1]                                                                          #
* Stabilization Interval                             [60]                                                                         #
* Restart Count                                      [3]                                                                          #
  Restart Interval                                   [198]                                                                        #
* Action on Application Failure                      [fallover]                                                                  +
  Notify Method                                      []
  Cleanup Method                                     [/home/script/oracle/ListenerClear.sh]
  Restart Method                                     [/home/script/oracle/ListernerRestart.sh]

clearup和restart的脚本很简单了，就是关闭和启动listener的2条命令而已。在此不赘述了。

由于对Oracle的监控，不单只是oracle进程是否活着这么简单了，还需要对oracle是否能响应请求进行监控，因此需要用Custom Monitor的方式来做。 HACMP恼人的一点就是，根本没有对通用软件的监控agent可以利用，所有的东东都必须自己写。所以费老劲儿了。。。

配置还是很简单的，主要如下：

                                                        [Entry Fields]
* Monitor Name                                        oraMonitor
  Application Server(s) to Monitor                    oracle                                                                     +
* Monitor Mode                                       [Long-running monitoring]                                                   +
* Monitor Method                                     [/home/script/oracle/SqlTest.sh]
  Monitor Interval                                   [30]                                                                         #
  Hung Monitor Signal                                [9]                                                                          #
* Stabilization Interval                             [180]                                                                        #
  Restart Count                                      [3]                                                                          #
  Restart Interval                                   [693]                                                                        #
* Action on Application Failure                      [fallover]                                                                  +
  Notify Method                                      []
  Cleanup Method                                     [/home/script/oracle/oraclear.sh]
  Restart Method                                     [/home/script/oracle/orarestart.sh]

SqlTest.sh的内容如下：

#!/bin/sh
ORACLE_HOME=/oracle/product/9.2.0.4
LOGFILE=/tmp/oracle.log

SU=/bin/su
OWNER=oracle

to_log()
{
        echo $1 >> $LOGFILE
}

show_time()
{      
        echo "[`date '+%Y-%m-%d %H:%M:%S'`]"
}

export ORACLE_HOME OWNER SU

#1.0 check the ORACLE_HOME
if [ ! -d $ORACLE_HOME ]
then
        to_log "`show_time` Oracle home directory $ORACLE_HOME does not exist"
        exit 99
fi

#2.0 check the SQLPLUS execute program
if [ ! -f $ORACLE_HOME/bin/sqlplus ]
then
        to_Log "`show_time` sqlplus does not exist"
        exit 99
fi

#3.0 check the ORAClE version
SQLRESULT=`$SU - $OWNER -c "$ORACLE_HOME/bin/sqlplus /nolog'" <connect / as sysdba
selecｔ version,status,logins from v\\\$instance;
exit;
EOF`

if [ `echo $SQLRESULT | awk -F"SQL>" '{print $3}' | awk '/.*ORA-/' | wc -l` -ne 0 ]
then
        to_log "`show_time` Monitoring returned the output :\n$SQLRESULT"
        exit 99
fi
to_log "`show_time` the Oracle Process is normal!"
exit 0

基本上就是这些东西了。希望能给后来者一点儿启发，细细
