Yes, these are vague problem descriptions.
The performance in some funtions are very slow,
no direct errors in the database log-file.

I spoke today to the programmers of the database application
to please trace/debug there code.

We will see.

Are you interested in linux queries with sysctl, ulimit, ipcs?
I tried to find some differences between openSUSE 12.2 and
openSUSE 13.1.

Best regards.

There is quite a lot of backports from 4.x mainline in Evergreen 13.1 
kernel (1802 patches at the moment). Some of those are memory management 
related or affect its code.

You might also try Leap 42.2 kernel (4.4, based on SLE12 SP2).

[Evergreen] Q: os13.1 with kernel 3.12

2016-08-24 Thread Achim Klausmann (V)

Hello,

is there back-ported Code from kernel 4.x in the evergreen kernel 3.12?
Is that memory related?

I'm running openSUSE 13.1 with an Oracle Database Express Edition 11 on 
several machines.

After updating from kernel 3.11 to kernel 3.12 via 'zypper up'
we got some problems in different database functions.

It's the same like having leap 42.1 with kernel 4.x
or Oracle Linux with UEK4 (kernel 4.x)

Unfortunately the older Oracle Linux version cannot installed
on Core-i-processors.

Best regards
