利用脚本，获取堆栈信息，方法如下：

sh ./core_stack /opt/gnode/server/bin/gbased opt/gnode/userdata/gbase/core.xxx  > file

文件名请记录节点信息，对应的core文件pid，时间等信息，以方便对照，例如bt_node17_pid_20160531.txt。

core_stack.sh
#!/bin/sh
gdb –quiet -nx $1 $2 <<EOF 2>&1
set width 0
set height 0
set pagination no
thread apply all bt
EOF

可以perl执行ssh命令，连接远程后执行bash脚本启动加载。

gbase命令行工具中支持通过system关键字的方式调用操作系统命令，用于更改当前路径、查看系统变量、查看文本内容。
命令格式为：system linux_os_cmd

例如：

gbase> system gcadmin

为了防止sh脚本执行进程丢失，可以编写sh脚本判断进程是否还存在。

#!/bin/sh
StartLoader(){
processnum=`ps -ef|grep Loader.sh|grep -v 'grep'|wc -l`
#echo "processnum=" $processnum
if [ $processnum -eq 0 ]
then
sh /home/gbase/gbloader/Loader.sh 
fi
}

main(){
StartLoader
}

processnum=`ps -ef|grep gbased|grep -v 'grep'|wc -l`
if [ $processnum -eq 1 ]
then
main
fi

为了周期性的自动执行操作某个shell，可以编写调度。
例如：每隔5分钟执行一次runloader.sh脚本

*/5 * * * * su - gbase -c "sh /home/gbase/runloader.sh"
