I've been an Oracle DBA for quite a number of years, working
on HP-UX systems. 

Now I'm also running some Oracle Application Server on 
Linux machines and I could use some advice about Oracle
and Linux.

For SL, I'm assuming I can call my SL 5.3 installation equivalent
to Red Hat 5.3 for Oracle support purposes?

In the Linux world things seem to move so fast.  We
have gone years between OS upgrades with HP-UX, and
even then there's not a lot of difference as
far as Oracle is concerned.

I'm checking the Metalink site for a support matrix
for various pieces of Oracle Application Server and
SL(Redhat) 5.3.  Things are all working in this configuration,
but I'm nervous that maybe I'm outside the supported setup.

Is it safe to do regular yum updates on a dedicated
Oracle App Server/SL 5.3 box?  Maybe I should just 
let it run at the  current configuration and not
chance breaking something.

As you can tell, I'm a bit apprehensive about the
speed of changes in the Linux world.  If anyone
knows a good resource for Oracle on Linux, I would
be willing to hook up with a consultant for a few
moments of good advice.
