Command Core Dumped

Q

为什么INFA的服务都运行地好好的，而执行命令时，却报错了。此时，内心是崩溃的:sob: :sob: :sob:

[pwc961@rhinfa961 ~]$ pmcmd

这种问题一般出在了环境变量的设置上。

这里以Linux为例，Library的环境变量：LD_LIBRARY_PATH

而profile一般为当前用户下的.bashrc 或者.bash_profile，个人比较喜欢使用.bash_profile。请看下面错误的profile中LD_LIBRARY_PATH的配置

[pwc961@rhinfa961 ~]$ cat .bash_profile 
### Oracle
export LD_LIBRARY_PATH=$LD_LIBARY_PATH:/lib:/usr/lib:/lib64:/usr/lib64:$ORACLE_HOME/lib
### PowerCenter
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$INFA_HOME/ODBC7.1/lib:$INFA_HOME/server/bin:$INFA_HOME/services/shared/bin:$INFA_HOME/services/shared/bin
### PWX 
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWX_HOME

正确的应该是:

[pwc961@rhinfa961 ~]$ cat .bash_profile 
### Oracle
export LD_LIBRARY_PATH=/lib:/usr/lib:/lib64:/usr/lib64:$ORACLE_HOME/lib:$LD_LIBARY_PATH
### PowerCenter
export LD_LIBRARY_PATH=$INFA_HOME/ODBC7.1/lib:$INFA_HOME/server/bin:$INFA_HOME/services/shared/bin:$INFA_HOME/services/shared/bin:$LD_LIBARY_PATH
### PWX 
export LD_LIBRARY_PATH=$PWX_HOME:$LD_LIBARY_PATH

这里并不是环境变量少了什么或者写错了什么，只是环境变量内部的顺序十分重要，因为它去搜索Library时是从左往右的顺序。所以写在前面的会优先搜索。再来测试一下：

strace命令

如果上面的方式并没有解决你的问题，请使用终极大招：strace命令,然后仔细查看错误信息，就可以定位了。
