查看oracle中path,查看oracle进程启动时的环境变量

当我们使用sqlplus本地登录oracle数据库时,设置的环境变量ORACLE_HOME和oracle启动时的环境变量ORACLE_HOME不一致时,会出现连接报错。

那么有什么办法可以看到oracle当时启动时的环境变量设置呢?总结一下:

Solaris:使用pargs –e

oracle@/proc/5032>uname -a

SunOS pcsweb-a 5.10 Generic_139556-08 i86pc i386 i86pc

oracle@/oracle>ps -ef|grep smon

AIX:使用ps eww

使用ps eww可以看到进程启动时的环境变量,不过都在一行显示,看起来很不方便。

可以使用如下命令查看:

oracle@ibmvs_a@/oracle $ ps eww 311336|tr -s " " "\n"|grep ORACLE_HOME

ORACLE_HOME=/oracle/product/10.2.0

LINUX:使用strings -a /proc//environ

oracle@mail@/oracle $ uname -a
