We are using zones here, we have only problems.

- unability to patch zones (we are using u3)

U3 is fairly old now.

- performance problems (thanks to processes block in kernel mode).


Can you elaborate on this please? Is there a bugid?

- and now the servers reboot itself in u5

bugid?


Solaris 10 is the most crappy release from Sun. You are taking Sun's blueprints/site like a reliable source. But it's only some ads from Sun, in fact the reality is by far different.

Can you point out which Blueprints are incorrect so
we can get them fixed please. It's also interesting
that you use this argument as a retort - did you
read the article linked by the OP? What would you call
that?


On the other side AIX and LPAR are working like a charm...


charm
• noun
1 the power or quality of delighting or fascinating others.
2 a small ornament worn on a necklace or bracelet.
3 an object, act, or saying believed to have magic power.

Seems somehow appropriate given the nature of your
post.

Yes and we paid to be early adopters of solaris zones.

Performance problem is mainly due to the fact that each zones share the same kernel. Thus when a software goes in kernel mode, the CPU time is not controlled anymore and the zone. So if there is a software bug during kernel mode, the zone will eat all the CPUs despite ressource control set.

Its no bug, it's the way zone are working.

you can find the bug ID (6696124) in the thread but Sun removed it for security reason ....

Can you give a concrete example of how to reproduce this problem so it triggers the said kernel bug?

Are you hitting these issues or just making hypothetical claims based on the design?

The same could be said for WPARs too. That's why Sun offers different virtualization technologies as does IBM.

The thread says a patch was delivered. The OP didn't post again so presumably it worked for them. Since they kept posting that they were unhappy, silence implies they are happy now.

I fail to see your point there. Are you saying AIX doesn't have bugs? I am sure a little searching will provide me with enough bugs where AIX boxes crash and reboot too.

Ignoring the sarcastic tone in the above post (as we do not use sarcasm here in the Middle East) the meaning is given here: http://idioms.thefreedictionary.com/work+like+a+charm:
work like a charm
if a plan or method works like a charm, it has exactly the effect that you want it to.

or
to operate perfectly.
