Hi,
Before I install the Oracle database 11.2.0.1 in Linux server 2.6.39-400.209.1.el6uek.x86_64, I created the following groups oinstall, dba, oper, and asmadmin.
groupadd oinstall # required from training
groupadd dba # required from training
groupadd oper # and group asmdba, asmoper from training
groupadd asmadmin # optional from training
I made a mistake when I created Oracle user account. I created it with dba as initial group“ useradd -g dba -G oinstall,oper,asmadmin oracle”, instead of “useradd -g oinstall -G dba,oper,asmadmin oracle”
After all I installed Oracle database, now I have concerns and questions. Should I use usermod to update the Oracle user account to oinstall as initial group or just leave it alone?
If I now do “usermod –g oinstall –G dba,oper,asmadmin oracle”, will it break anything, any impact to the database?
