First question that comes to mind: what has happened between yesterday and today?

  • The PATH variable has been modified?
  • mc has disappeared from the PATH?
  • The libraries libglib-2.0 and libgmodule-2.0 have changed?

A system update / upgrade?
.profile modification?

Hi RudiC,
ours developers compile external library for oracle. They may be installed some software with yum.

4

I am more worried by the fact developers have root passed or access to it (sudo?)
How can a sysadmin guarantee a system's integrity if others can modify it binaries, libs without him or his team know?

The most common case is when a new version of an installed product or new product needs a more recent lib than installed, the nightmare case being mixing open source product from 2 different worlds like IBM and the other I forgot the name...

vbe you are more then right. This LPAR is test env in this moment. After successed test will be reinstall and import oracle db which will be prod system.
