JStorm Worker程序启动连不上Oracle

时间：2021-01-31 07:47:00
  最近遇到jstorm的worker程序在启动时报包不到oracle的.so包的错误。
  初步是环境变量LD_LIBRARY_PATH的设置问题导致的,经过比较后发现本机上的LD_LIBRARY_PATH上设置了的,但是依然报错提示找不到.so的包。
  于是考虑jstorm的work进程是通过supervise拉起来的，通过查看supervise的日志发现，用的是nimbus主机的上环境变量$LD_LIBRARY_PATH,而本机的.so包所在目录与nimbus又不一样，所以找不到相应的.so包。
 
supervise日志如下: 
[INFO 2018-06-13 19:58:59 c.a.j.d.s.SyncProcessEvent:842 EventManagerImp] Environment:{Lupervisor.log_LIBRARY_PATH=/usr/local/lib:/usr/lib:/opthb/release/JStorm/lib/dcclib:/oracle/app/oracle/product/db11gr2/lib:/timesten/TimesTen/tt112280/lib, REDIRECT=true}

worker程序报错日志:

结论:storm集群所有主机的安装环境，目录这些必须要一样才能保障不报错。
