SuSe and Oracle11- why SLES9 is notsupportedwhile RHEL4 (and O 2007-08-13 - By Alexei_Roudnev
Back
Here comes another problem. It's why I argued with Novell on all 'version
1', explaining that they publish system of 'Open Beta' quality as 'Release'
and so shorten life time dramatically.
SLES9 - release was not usable (virtual memory problems, iSCSI problems,
stability problems) - only SLES9 SP1 became usable (and only SLES9 SP3
became rock solid, after upgrade 283). SLES10 release was not usable - only
SLES10 SP1 became partially usable.
If we look onto RHEL5, we will see that they had a very long (almost a year)
Open Beta period when everyone could download system, try it, write a
software, but system was not counted as a production so these 5 years was
not counting yet. As a result, their '-release' comes in time of 'SLES* SP1'
but have already good software and hardware vendors support and have a rock
solid quality of SLES* SP1. Just because ythey don't pretend that their
'Beta' is 'Release'.
If we look into the SLES life span - they release useless -release but start
counting 5 years from this time. And, worst, they abandon hardware support
for the old version since this very moment (purchase DELL. You can order
RHEL4, RHEL5, SLES10 but not SLES9. Why? Take ET64T server - SLES8 never was
modified to support this platform /RHEL3 was modified/.)
I (and many, MANY, users) DONT NEED SLES10 on a servers. I don't need all
these new changes - they all are weird and not stable. New ISCSI is
terrible. New YOU system is terrible. New installation system is very
flexible but extremely slow - I was 100% satisfied with SLES9 installation
system on servers /only on servers/. New libraries lost old thread support.
System is not Oracle9 compatible. Oracle have a strange errors with standby
logs when running on SLES10. I don't want to be a beta tester on production
systems. All I need is a system of SLES9 SP3 quality (not of SLES10 SP1
quality), with full support on new hardware (including new DELL servers, new
SUN servers, new HP servers - exceptions possible but they must be
exceptions), compatible with all 3 major Oracle versions, and having at
least some basic software updated (heartbeat2 - why it is not installed as
an option? It's pretty simple).
If we are talking about SLES10, I can count 5 years from this June - when
SP1 was released and system became usable. Not from SLES10 - release - it
was pretty useless system. I can understand if Novell stop migrating SLES9
onto new platforms when SLES10 is (counting from June) 2 years old. But
now... hmm, I don't want to be an experimental rabbit (to be honest, I like
to be - in the lab, so I wil test it all - but not in prod).
And I am software engineer (not just sysadmin) so I can bear _Beta in
production_... Many other sysadmins (esp who are not software engineers) do
not have enginering skills and have only one choice after all. And you can
guess, which one.
PS. OpenSuSe is a great system (I put it ahead of Ubuntu after few
experiments). SLED is a great system. Problem is that SLES is for _SERVERS_
and can't bear 'SLED' or 'OpenSUSe' quality and variability. SO it should
not be so volative as SLED or OpenSUSe.
PPS. Strange, but FreeBSD life span is much better, too. They support 2
systems at once all the time (FreeBSD 5 and FreeBSD 6 for now), and switch
from the old system on approximately 10-th - 15-th release of the new
system.
