Why does Oracle’s applications needs xscreensaver in order to run ?

Working with some of Oracle’s products, made me wonder about their installation requirements as appears in the documentation.

Let start with Oracle® Database 10g Release 2. The installation guide for linux x86 says under “Checking the Software Requirements” it needs the following RPMs for RHEL 4.0:

  • binutils
  • compat-db
  • compat-libstdc++-296
  • control-center
  • gcc
  • gcc-c++
  • glibc
  • glibc-common
  • gnome-libs
  • libstdc++
  • libstdc++-devel
  • make
  • pdksh
  • sysstat
  • xscreensaver
  • setarch

Most of them are valid requirements when needing to compile C/C++ code (as it may be done inside the database). But why do I need to install gnome’s libraries, gnome’s control-center and xscreensaver?

I fail to see how are these 3 are related to running a database. It is reasonable to require these packages for running a graphical installation, but that’s not a runtime requirement! I even tested that with checking the database opened files while it’s been running.

I really don’t want to have these packages installed on servers unless I must, as I believe server should contain the minimal software required on top of the distribution default installation.

Another funny (and weird) fact is that for SELS 9.0 there isn’t any requirement for gnome’s control-center. For RHEL 3.0 there aren’t any requirements for the 3 packages…

Mentioning optional requirements are probably the best why to solve this, unless there’s some real requirement that eludes me. John Smiley’s “Installing Oracle Database 10g Release 2 on Linux x86″ has this for openmotif21 which is mentioned as needed only for Oracle demos.

The same happens for Oracle® Enterprise Manager in installation guide for linux x86 10g Release 2 (10.2), but this time the package requirements for RHEL 3.0 and SELS 9.0 don’t mention any of the 3 packages, whilst they are required for RHEL 4.0. Very weird.

The status for Oracle Application Server 10g Release 3 is similar.

I would be happy if someone could shed some light on the issue.
